THEORY OF OPERATION

 


In order to understand and properly communicate with a FASFAX Technician by telephone, it is extremely important to know the following diagrams, and Theory of Operation used by FASFAX for this product.

1. The FASFAX Mark 4 Systems are designed with one central processor, called a MASTER ENCLOSURE, which is located in the bottom of the MASTER TERMINAL. In a restaurant with only one register, that terminal is always a master terminal. If there are more than one terminal, the master is usually located at one end of the front counter.

2. In a restaurant where more than one register is being used, all additional units are known as SATELLITE or SLAVE TERMINALS. All terminals contain a switch, called an address switch, with a numerical setting called the address. By setting the switch in each terminal to a different address, and with the help of a sophisticated DATA cable called a TWINAX or BLUE WIRE, the memory can transmit data to or from any address. ( See diagrams on next pages).

3. REMOTE PRINTERS are usually installed at a pickup counter, or in the kitchen, and provide employees with a numbered copy of the receipt, which helps in the preparation and delivery of each order.

4. A CRT MONITOR is installed at each kitchen workstation. It provides visual communication between the register terminals on he front counter and the kitchen employees, to aid in product preparation.

5. A MULTICHANNEL CRT INTERFACE is installed in the kitchen area, and provides the CRT's with information form the memory necessary to prepare an item. EXAMPLE: Hamburger, no ketchup, no pickle, etc. (See next pages).

6. A BUMP BAR is also installed at each kitchen workstation , and is used to remove items form the CRT Monitors as they are prepared. The Bump Bar, like the CRT Monitor, is also wired to the Multichannel Interface. (Bump Bar not shown)

THEORY OF OPERATION COMPONENT IDENTIFICATION

 


The MASTER ENCLOSURE or CPU, (Central Processing Unit), is the unit that is located in the bottom of the Master Terminal. Its primary function is to collect and store all information the user programs into it either by hand or with a LOADER.

There are two types of information to load into the system. The first is the factory PROGRAM. This factory tape or disk can only be load with the use of a tape or disk loader, and cannot be altered in the field. The factory program's function is to provide the CPU with a list of operating instructions that allow the user to manually type in needed information such as menu items, prices, recipes, labor, etc. This is the second type of information, known as the DATA. Once the data has been manually entered for the first time, it can be stored on a tape or disk for future use, much like the factory program. (See next page for diagram of theory.)

The Master Enclosure has four LED light indicators, A, B, RUN, and DC (see example #1, page 6). These A, RUN, and DC lights must be on at all times in order for the system to function. The B light is not required. The A and RUN LEDs tell us that the CPU has a working Program and Data. DC tells us that it is receiving the proper DC voltage to operate. If any of these LEDs are not lit, there is a problem, and the troubleshooting guide in this manual should be consulted.

Next to the LED indicators there are two small plugs or PORTS where the blue communication cable (Twinax) is connected (See example #2, page 6). The female end of the short blue twinax cable should be connected into the port closest to the A light (see example #3, page 6). The male end will be connected into TERMINAL INTERFACE CONTROLLER or T.I.C., which will be discussed on page 10.

Located next to the LED marked DC , is a small, nine pin receptacle (example #4, page 6), where the power cable from the POWER SUPPLY (example #5, page 6), for the CPU is connected. If this cable is removed from either end, ALL DATA AND PROGRAM WILL BE LOST. Take special care when working in this area.

There is also a larger, 25 pin receptacle that is labels EIA LOADER (example #8, page 6). This receptacle is used as an access port to the memory when loading or retrieving information with a LOADER.

THEORY OF OPERATION COMPONENT IDENTIFICATION MARK IV POWER SUPPLY

 


The MARK IV POWER SUPPLY performs several function, and also aids the user in troubleshooting unexpected problems. The following is a list of features of the Power Supply:

1. Receives incoming AC voltage and converts it to useable DC voltages to serve all internal register components.

2. In the front right corner of the power supply there is a black button called the POWER INTERRUPT SWITCH, which allows the AC power for the register to be momentarily cut off. (See example #3 on next page. This switch should be HELD IN whenever the register is plugged in and components are installed, or fuses are replaced.)

3. During a power outage situation, the power supply automatically converts to a six-volt backup battery to retain the CPU memory until AC power can be restored. (See example #2, next page.)

4. During normal operations, it supplies the backup up battery with a constant seven volt DC charge to insure the battery is fully charged at all times.

5. The power supply has a INTERNAL FAN which supplies cool air to all internal components to prevent overheating. (See example B, next page.)

NOTE: DURING NORMAL OPERATIONS THE FAN MUST ALWAYS BE TURNING

6. The power supply has several fuses. These protect the internal components of that register from damage caused by power surges or shorts. (See example #1, next page.)

NOTE: BAD FUSES MUST BE REPLACED ONLY WITH THE SAME SIZE FUSE AND WHILE THE POWER INTERRUPT BUTTON IS HELD IN.

7. There are several LEDs on the top of the power supply that help to indicate where a problem might be in the unlikely event of a failure. (See example #6, next page.)

NOTE: DURING NORMAL OPERATION ALL LEDs ON THE POWER SUPPLY MUST BE ON.

8. In the master register, the power supply also provides power for the tape/disk loader. With an adapter (example #5, next page) attached to the TIC power cable, the loader can be plugged in and operated from that register. (See example on page 13.)

9. It is suggested that preventative maintenance be performed at least once every six months to insure good operating conditions for longer component life.

THEORY OF OPERATION COMPONENT IDENTIFICATION MARK IV TIC

1. THE TERMINAL INTERFACE CONTROLLER or TIC, is located just below the printer and acts as an interface, or dispatcher, in each register. Its functions are as follows:

A. To receive DC voltage form the power supply and send the proper DC voltage to each component in that register (printer, keyboard, displays).

WARNING: DO NOT UNPLUG OR PLUG IN THE TIC POWER CABLE FROM THE POWER SUPPLY WITHOUT FIRST HOLDING IN THE BLACK POWER INTERRUPT BUTTON ON THE FRONT OF THE POWER SUPPLY. COMPONENT DAMAGE WILL OCCUR IF THIS IS NOT OBSERVED.

B. Information is relayed to and from the memory and routed to the proper components within that register, i.e., printer, displays, keyboard. During normal operating circumstances there are two LEDs on the top of every TIC that flash when communication is taking place with the CPU. They are POLL and ANSWER. If these LEDs are not flashing there is a potential problem, and the Troubleshooting Guide in this manual should be consulted.

C. The TIC provides us with a diagnostics system called SELF TEST. By using the Self Test switch (example #1, page11) in conjunction with the address switch (example #2, page 11) and several LEDs (example #3, page 11), the TIC helps the user determine the operating condition of each individual component in that register. In this manual you will find a Self Test guide with instructions for activating this function and performing each test.

D. The Mark IV TIC also contains a special feature known as STAND-ALONE. Each Mark IV TIC is equipped with 16k of RAM MEMORY. In the unlikely event of a CPU failure or a total system TIME OUT, the TIC memory can take over. This feature can be used at each individual register to take customer orders, and a limited amount of reports needed to operate the restaurant, until the failure can be corrected.

In order to properly enter STANDALONE, a list of instructions and keystrokes have been supplied in this manual.

THEORY OF OPERATION COMPONENT IDENTIFICATION MARK IV DOT MATRIX PRINTER MARK IV KEYBOARD MARK IV DISPLAYS

 


THE DOT MATRIX PRINTER receives signals from the TIC which are then transmitted to seven small pins located in the Printer Head. These pins fire outward into an ink ribbon and create an image on paper. Unlike the drum printers, Dot Matrix is much faster and allows full alphanumerics, which gives the user a more legible printout.

In order to properly maintain this Printer a few rules should be followed:

1. DO NOT PULL ON THE PAPER WHILE THE PRINTER IS PRINTING, OR DAMAGE TO THE PRINT PINS MAY OCCUR

2. YOU MUST DEPRESS THE BLACK POWER INTERRUPT SWITCH LOCATED ON THE FRONT OF THE POWER SUPPLY BEFORE REMOVING OR INSTALLING A PRINTER POWER CABLE. INTERNAL DAMAGE WILL OCCUR IF THIS IS NOT OBSERVED.

3. BEFORE INSERTING THE PRINTER POWER CABLE, MATCH THE PAINTED MARK ON THE CABLE WITH THE PAINTED MARK ON THE PRINTER TO INSURE PROPER CONNECTION.

THE MARK IV DISPLAY is a one piece unit that supplies visual information to both the customer and the operator. It connects directly to the display port at the rear of the TIC.

Some care should be taken when installing this display.

1. The painted mark on the display cable should match the painted mark on the back of the TIC before inserting the plug.

2. The display cables must be free of folds or twists.

3. The display tubes are made of glass. Use proper handling so as not to break the tubes.

THE MARK IV FLAT KEYBOARD is used by the operator to send commands to the memory through the TIC. The keyboard cable connects to the rear of the TIC., adjacent to the display cable. Some care should be exercised when installing this keyboard.

1. Match the painted mark on the keyboard cable connector with the painted mark on the rear of the TIC before inserting, to insure proper connection.

2. The keyboard cable should be neatly clipped to the inside of the register lid, so damage will not occur while opening and closing the lid.

3. When installing the keyboard, do not over-tighten the retainer nuts; snugly tightened should be sufficient.

TROUBLESHOOTING PROBLEM IDENTIFICATION & REFERENCE GUIDE

 


POWER FAILURES in the restaurant or on the FASFAX line will cause the displays on each register to go blank and the system will not respond to any keystrokes.

1. TOTAL RESTAURANT POWER FAILURES:

1A. Disconnect all machines AC power cord to avoid a possible damaging surge when power is restored.

1B. Open the Master Register, the two LEDs on the power supply marked BATT CPU and BATT TIC should both be on. This shows that the battery is supplying power to the CPU to hold the memory, and will support the memory for up to four hours depending on the battery condition.

1C. If a power failure is expected to last longer than four hours the master register can be moved to a location that has power. This may avoid the loss of valuable data that has accumulated that day. NOTE: THE ALTERNATE LOCATION MAY NOT HAVE A TWISTLOCK OUTLET. A STANDARD LINE CORD WILL BE NEEDED. (PART #YCR-50C)

1D. Once the power has been COMPLETELY restored, depress the POWER INTERRUPT switch while re-connecting each register. Approximately thirty seconds after plugging in the master register all units should print; "RESTART SYSTEM IN". NOTE: TO AIDE IN THE RESTART PROCEDURE PUSH ANY KEY ON EACH REGISTER.

1E. If after five minutes the registers do not restart refer to page 32 in this manual for DATA Recovery Procedures.


2. POWER FAILURE ON FASFAX LINE ONLY:

2A. Displays will be dark, all internal LEDs will be OFF, and keyboards will not respond.

2B. Disconnect AC power cables for all machines, go to the circuit breaker for the FASFAX POS SYSTEM and reset it.

2C. Depress the black POWER INTERRUPT switch on ONE register, insert the power cable, release the switch and allow time for the register to power up. A ZERO, or the word TIMEOUT should appear in the display. If so, continue to re-connect all other units. If the display remains blank, that register should be unplugged.

TROUBLESHOOTING PROBLEM IDENTIFICATION & REFERENCE GUIDE

COMPLETE SYSTEM FAILURE is defined as ALL REGISTERS DOWN. Each register must be inspected. If one is found to be in good working order you must refer to the page in this manual that covers multiple registers down. A complete system failure can be caused by one of the following:
            1. A power failure longer in duration than the life of the backup battery.
            2. The FASFAX circuit breaker being turned off overnight, exceeding the life of the battery.
            3. A power surge that exceeds the Power Supply's ability to properly filter it.
            4. Component failure. In the unlikely event the CPU or Power Supply in the Master Register were to fail, this
            could result in a possible loss of memory.
The following procedures are steps that must be taken to repair the problems listed above. It is suggested that a FASFAX technician provide you with telephone assistance while performing these procedures.
(NOTE: IN ORDER TO ACHIEVE THE BEST RESULTS THE FOLLOWING STEPS MUST BE FOLLOWED IN THE ORDER THEY ARE LISTED.)

1. Open the master register. On the bottom right- hand side there are three LEDs that should be on; A, RUN and DC. If all LEDs are ON, proceed to STEP #2. If any one of the three are OUT, go to STEP #5 - A & B.

2. NOTE: IF THERE IS ONLY ONE REGISTER IN THE RESTAURANT TURN TO THE PAGE IN THIS MANUAL THAT COVERS SINGLE REGISTER FAILURE. DO NOT CONTINUE IN THIS SECTION.
If you have more than one register and all LEDs are on, perform the following: Inside the master register, unplug the LONG, blue twinax cable that connects the TIC to the next register. Check to see if the Master Register now works. If so see the page in this manual that covers MULTIPLE REGISTERS DOWN for instructions

3. If the master register does not become operational, remove the SHORT blue twinax cable form the TIC, and join it to the LONG cable you removed in STEP #2. This will bypass the master register. If the other registers begin operating, see page 14 of this manual for troubleshooting a single register.

COMPLETE SYSTEM FAILURE; CONT.

 


4. If none of the registers downline become operational, unplug the two twinax cables you joined together, remove the SHORT twinax cable from the master and insert the LONG cable into the A port on the CPU. This will bypass the short twinax. Now check all registers downline, if they are operating, the SHORT twinax must be replaced. NOTE: AT THIS POINT, IF NONE OF THE REGISTERS ARE OPERATIONAL, RETURN ALL BLUE TWINAX CABLES TO THEIR ORIGINAL POSITIONS AND CONTINUE TO STEP #5.

5. IF ALL LEDs ARE ON and you have completed STEPS 3 and 4, or you only have ONE REGISTER, use the instructions in this manual to connect the tape/disk loader and perform a GO START. This should cause all the registers to RESTART. If so, check to see that each unit is operational, disconnect the loader, set the date and time, and resume normal operation. If the registers DO NOT restart, proceed to STEP #6.

5A. IF THE A OR RUN LEDs, OR BOTH, ARE OFF, use the instructions in this manual to connect the tape/disk loader and perform a GO START. This should cause all the registers to RESTART. If so, check to see that each unit is operational, disconnect the loader, set the date and time, and resume normal operation. If the registers DO NOT restart, proceed to STEP #6.

5B. IF THE DC LED IS OFF, this is an indication that the CPU is not receiving power. This problem does not occur often, but if it does check the following:

1. Make sure that the master register is plugged into the power supply AND the wall outlet.

2. Make sure the CPU power cable is securely connected at both ends. (Blue, ribbon cable from the power supply to the CPU ((next to the DC LED)).)

NOTE: DO NOT disconnect the CPU power cable or program and data will be lost.

3. Make sure the LEDs marked MASTER, +5 MASTER and -12 MASTER on the top of the Power Supply are illuminated.

4. Make sure the fuse marked MASTER 2amp F/B is good. (If the fuse is bad, the LED on the left should be out. When you replace a fuse remember to depress the Power Interrupt Switch. NEVER use a metal object (like a screwdriver) to remove the fuse.

5. If the DC light is still off after you have taken the above steps, there is a strong possibility that a power supply or CPU failure has occurred.

NOTE: IF THE DC LIGHT IS NOT ON AFTER THE ABOVE STEP, DO NOT PROCEED FURTHER WITH THIS GUIDE. CALL A FASFAX TECHNICIAN.

6. If you are unable to generate a GO START. or if you were successful, but the system has locked-up again, you must now perform the following steps:

NOTE: EACH OF THE FOLLOWING STEPS REQUIRE INSTRUCTIONS WHICH MAY VARY DEPENDING ON YOUR TYPE OF LOADER. PLEASE USE THE TAPE LOADER OR DISK LOADER INSTRUCTIONS IN YOUR FASFAX MANUAL TO COMPLETE EACH STEP.

A. CONNECT the loader to the master register.

B. DUMP DATA, you are trying to copy any sales or information that may have accumulated for that day.

C. "CLEAN BLIP" PROGRAM & DATA - You are completely clearing the registers memory, to eradicate the potentially damaged program that could interfere with the successful reload of program & data

D. LOAD FACTORY PROGRAM - Input all CPU operating instructions.

E. LOAD DATA DUMP - Input sales information which you attempted to save in step B.

F. GO START - You are telling the CPU that you have completed the load, and you are ready to restart the system. With some programs "CLEAR ALL must be pressed on EACH register in order to restart the system. If you are successful in generating a restart, proceed to step G.

NOTE: IF YOU ARE UNSUCCESSFUL, PROCEED TO STEP H.

G. If you are successful in generating a restart, you should attempt to run several reports, check sales, and ring a test sale. If these are successful, enter the time & date: [MGR SAYS]-[INTERLOCK[(TIME)]-[OPERATOR A]-[(DATE)]-[NO SALE]. After completing the above keystrokes you may disconnect the loader and resume normal operations.

H. If you CANNOT successfully generate a restart, the problem may be in the Data Dump. You must now load the original program disk or tape made for your restaurant when your FASFAX system was installed. Follow the loader instructions for LOAD DATA to complete these steps. Once you have completed the load, you must repeat step F and complete step G.

NOTE: BECAUSE THIS DATA WAS MADE AT AN EARLIER DATE, PRICES MAY NEED TO BE UPDATED. CASH DRAWERS WILL NEED TO BE RE-ASSIGNED, AND IF SALES FROM AN EARLIER DATE ARE PRESENT, A "DSR" MUST BE RUN.

TROUBLESHOOTING PROBLEM IDENTIFICATION & REFERENCE GUIDE SINGLE REGISTER FAILURE

 


SINGLE REGISTER FAILURE is defined as; all units are in working order except one. That register may be COMPLETELY DOWN, or may function but have MINOR COMPONENT PROBLEMS that prevent the register from functioning properly; i.e.., display cable out, keyboard not responding, printer not functioning. This section attempts to solve these minor problems, or directs you to call for help when needed. You must go to each register and check to see if ti is operational. If any other registers are COMPLETELY DOWN, refer to the section in this manual that covers MULTIPLE REGISTERS DOWN. If all other units are operating, but have MINOR COMPONENT PROBLEMS, you may remain in this section and complete one problem at a time.

NOTE: IF YOU ONLY HAVE ONE REGISTER IN THE RESTAURANT, THAT REGISTER IS OBVIOUSLY THE MASTER REGISTER, AND YOU SHOULD TURN TO THE PAGE IN THIS MANUAL THAT COVERS "COMPLETE SYSTEM FAILURE". FOLLOW THOSE INSTRUCTIONS FIRST BEFORE CONTINUING IN THIS SECTION. IF YOU HAVE ALREADY DONE SO, PLEASE GO TO STEP #2 IN THIS SECTION.

NOTE: AS EACH STEP IN THIS SECTION IS COMPLETED, AND A PROBLEM IS FOUND, AND CORRECTED, THE REGISTER OPERATION SHOULD BE TESTED. OF THE PROBLEM HAS BEEN SOLVED, RESUME NORMAL OPERATION AND DO NOT CONTINUE FURTHER IN THIS MANUAL.

1. ONE UNIT COMPLETELY DOWN - Go to a register that is in good working order and press "CLEAR ALL" - 41838 - "DELETE". This will cause all units to restart, and possibly restart the register that is down. If this register restarts check to see if it is operational, if so resume normal operations. 1A. If the register DOES NOT restart, continue to step #2. 1B. If the register restarts, but STILL DOES NOT FUNCTION, go to step #5 for instructions. 2. Open that register and check the lights(LED's) on the TOP of the power supply. ALL LED's should be on. If so, continue to step #3. If not complete steps 2A through 2C.

2A. If all but two LED's on the power supply are OUT, check the POWER CORD for a proper connection at the register AND at the wall outlet.

2B. If only ONE or TWO LED's on the LEFT side are out, depress the black POWER INTERRUPT SWITCH and replace the fuse corresponding to the LED that is out. 2C. If an LED is out on the RIGHT side, there is possibly damage to the power supply.
 
 






PAGE 23




TROUBLESHOOTING PROBLEM IDENTIFICATION & REFERENCE GUIDE SINGLE REGISTER FAILURE; CONT.

 


3. Check all LED's on the TIC. The POLL and ANSWER LED's should be blinking and no others should be on (ROLL PRINTER JAM may be lit but in very common). If so skip to step #4. If POLL and ANSWER ARE NOT blinking, see steps 3A & 3b for instructions. If POLL ERROR is lit also see 3A & 3B. If the SELF TEST LED is lit, see step 3C.

3A. Check the BLUE TWINAX cable in this register, and all other registers and printers. Make sure that all are firmly plugged in, so that this unit is properly communicating with the memory. Also check the ribbon cable that runs from the power supply to the TIC. This cable must be securely connected.

NOTE: IF THIS CABLE HAS BECOME LOOSE, YOU MUST DEPRESS THE "POWER INTERRUPT SWITCH" BEFORE INSERTING THE CABLE!

3B. On the front of the TIC, there is a rotary ADDRESS SWITCH with a small window that displays a number. This switch must be set between 0 and 9 (0 and 7 for 512K programs). The number identifies the address of the register, and must be different from all other registers and printers. If the register address is set the same as another unit, neither will function properly. Register and peripheral addresses are determined by the program being used. Consult program documentation.
 



 



3C. If the LED marked SELF TEST on the TIC is ON, a small silver toggle switch on the right side of the TIC must be pushed to its forward most position. This returns the register to its normal, operating mode. Reset the address switch to its' proper number, and continue normal operation.

4. On the left side of the TIC there is a short, wide cable that connects the TIC to the printer. See the diagram of the MARK 4 Printer in this manual.

4A. If the printer cable has become disconnected or seems loose, depress the POWER INTERRUPT switch on the power supply, and push in the plug on both ends.

4B. Also make sure the painted mark on the printer cable is on the same side as the painted mark on the printer.

NOTE: REMEMBER, THE POWER INTERRUPT SWITCH MUST BE HELD IN WHENEVER A TIC OR PRINTER IS PLUGGED IN.

5. Inspect the LED marked KEYBOARD on the TIC. This LED should blink as you press any key. IF so, continue to step #6. If not, see step #5A.

5A. Open the lid and locate the gray, flat 1" cable that connects the TIC to the keyboard. Check to see that it is securely connected to the keyboard. Make sure that the painted mark on the cable is on the same side as the painted mark by the hand screw that holds the TIC in place. Slide the TIC forward. Trace the keyboard cable path to the back of the TIC, and push IN on the plug.

6. The MARK IV Display should always display something. It may be a zero, a number or a TIMEOUT. If the register display is completely blank or blinks off and on, and you have completed all of the previous steps in this section, then check the following:

NOTE: DO NOT REPLACE THE FUSE UNLESS THE LED IS OUT.

TROUBLE SHOOTING
MULTIPLE REGISTERS DOWN

1. MULTIPLE REGISTERS DOWN is defined as TWO OR MORE units not operating, but not the entire system. This usually means that the same problem is effecting each.

NOTE: IF ALL REGISTERS ARE DOWN, SEE THE SECTION IN THIS MANUAL FOR "COMPLETE SYSTEM DOWN".

PAGE 26



TROUBLESHOOTING
SUBJECT: CRT MONITORS

1. ALL CRTs FAIL TO DISPLAY; In this situation the same problem is usually affecting all CRTs. The majority of
these problems can be corrected by completing the following steps in order. Proceed to step 1A after verifying that
CRTs are all turned on and brightness control is not turned completely down.

            1A. Go to a working register and press [Clear-all, 41383 DELETE]. This will restart all registers and CRTs.

            1B. If CRTs still do not operate, disconnect the blue, twinax cable from the CRT Interface, then unplug the
            CRT Interface POWER CORD (black square plug) from the interface. Wait ten seconds then watch the monitors
            while you do this, reconnect the POWER CORD and blue twinax. A test pattern should appear for a few
            seconds then disappear. This will tell you that the Interface is sending a signal to the monitors.
            After the test pattern disappears, go to one of the bump bars and press any button. The CRT should now
            show the channel marker on the bottom right of each CRT and you can resume normal operation. If the channel
            marker does not appear on any monitor then repeat this procedure a second time.

            1C. If the channel markers do not appear after two tries of 1B then check the blue wire at the interface then at
            all other Fasfax equipment to ensure proper connections. Located next to the blue wire(s) on the interface is small
            white or black rocker switch. Be sure the switch is in the "ON" position.

            1D. Located on the left side of the interface are three LEDs (lights) and two fuses. These LEDs should all be on
            and the middle one should pulsate. The fuses must be good or some LEDs may not be lit. Replace any blown
            fuses with the proper amperage replacement. If no Leds are on, or only the middle one is pulsating, it is a good
            possibility that the unit is not receiving power. Check both ends of the power cord, and check to see if a
            breaker has tripped.
           NOTE: USUALLY IF THE BREAKER HAS TRIPPED THAN THE ENTIRE SYSTEM IS DOWN
           UNLESS THE UNIT IS ON A SEPARATE CIRCUIT.

            1E. After completing step 1D above, disconnect the blue twinax cable(s) and the interface power cord
            again. Wait ten seconds and plug the power cord back in. If the CRTs do not shown a test pattern after
            several attempts, the interface may be defective. If  a test pattern does appear, replace blue cable(s) and
            press any button on a bump bar. The channel marker should appear in the bottom right corner. If you get
            a test pattern but no channel marker proceed to the next step.

            1F. Using your program manual, enter the keystrokes to reassign each channel. If you are using option
            numbers reassign the desired option. Also make sure that the menu items you are trying to display are
            assigned to a channel and/or option. After completing these steps enter [CLEAR-ALL, 41831 DELETE]
            and restart the system.
 
 





PAGE 27




 


            1G. If the program or interface have just been changed make sure that the address switch (located inside
            the unit) is set to the correct setting as list in your program documentation.

            1H. If you have completed all of the above steps and the CRTs still do not function, follow the instructions
            in this manual for reloading the ORIGINAL PROGRAM disk or tape.

            1I. If none of the above correct the problem, call you service technician.

TROUBLESHOOTING
SUBJECT: SINGLE CRT FAILURE


1. SINGLE CRT FAILURE

            1A. Make sure the CRT is receiving power. This can be accomplished two ways. Next to the CRT ON/OFF
            switch there is a small red LED. This should be ON whenever the switch is in the ON position, and power is
            present. An alternate way to check the CRT for power is to increase the brightness and contrast controls to
            the highest setting. This should brighten the monitor. If these signs of power are not present check the CRT
            power cable at the outlet.

            1B. If you have power but no information is being displayed, check the black coax cable connected at the
            back of the monitor AND at the interface. If the malfunctioning monitor is channel #1 the cable will be
            connected to the FIRST video module (most left) at the interface. Channel #2 is the second card and so on.

            1C. Remove the coax cable from the interface that goes to the CRT you are working on. Connect the cable
            to another video module that is working properly. If the malfunctioning CRT still does not have information
            displayed then the problem is the cable itself or the CRT monitor and a technician should be called. If it
            DOES display information then the problem is with either the video module or the interface's ability to
            to send information to that video module. (See next step).

            1D. Using your program manual, enter the keystrokes to reactivate that channel. If you are using option
            numbers reassign the desired option. Also make sure that the menu items you are trying to display are
            assigned to this channel and/or option. After completing these steps enter [CLEAR-ALL, 41831 DELETE]
            and restart the system.


2. BUMP BAR FAILURE

            2A. Check the bump bar cable for loose connections, both at the bump bar and at the interface unit.

            2B. Check for a defective Bump Bar switch. This usually can be done by pressing each switch. A
            defective switch will usually feel loose or won't press at all.

SYSTEM PROBLEMS

 



                 Normally there are three types of problems which can be encountered during
            normal operation of the system. Each should be looked at in a different light.

            1. SYSTEM RESTART - Suddenly the entire system stops working for several
            seconds, and then every machine prints the message "RESTART SYSTEM IN"
            on the printers. No action on the part of the Manager is usually needed, and
            nothing is "lost"' except any orders in process, which were not yet totaled, and
            any orders on the CRTs and at the Expediter Printer(s). The most common
            cause of this action is an incoming power fluctuation which the power supplies
            "see" and go onto battery momentarily to try to protect the system. Sometimes
            they are unsuccessful, and parts of the program are lost due to the surge.
            Sometimes the memory just loses command of the system and a GO command
            by using the Disk Loader, or recycling power on the master as a last resort, will
            cause it to finish the restart and print "RESTART SYSTEM IN". (Recycling power
            is a last resort, because if your battery has gone bad, you will lose everything in
            the machine.)

            2. SYSTEM ERROR - Suddenly the entire system stops working for several
            seconds, and then one of the registers prints "SYSTEM ERROR" and a series of
            numbers in this format:
               XXXXX
                  XX
               XXXXX
               XXXXX
            and then the entire system prints "RESTART SYSTEM IN". Usually, the system
            is back to normal at this point, except for what was lost due to the restart. This
            action is usually due to the software being asked to perform a task which is
            illogical to it. It may be illogical because of a software bug, or because parts of
            the program have been corrupted by a power surge. In rare instances it may be
            due to memory going bad. There are variations on this. It may be that the system
            error displays on one of the kitchen CRTs or all of them, and the system locks
            up. If one of the registers has not yet locked up, a 41838 - DELETE may allow
            the system to finish the restart, and operation will resume. If not, a GO
            command, or as a last resort, recycling power in the master, may allow the
            system to finish the restart. (Recycling power is a last resort because if the
            battery has gone bad, you will lose everything in the machine.)
                 Getting to the root of a System Error can be tricky, and we need all the
            information we can get. The first thing we need are the System Error numbers.
            These often tell the programmer where to look for the problem. We also need to
            know as much about the store situation during the error as possible. Busy or
            slow? Anything on the CRTs? Which CRTs? How big a backlog? Who had just
            totaled an order? What was on the order? Anything unusual? Anything else
            going on? Report being run? Someone just clock in/out? Did they try to use an
            illegal employee number? In some cases it may become necessary for the store
            to get a PROGRAM & DATA DUMP while the error and lockup have taken place.
            Our Technicians can then "look into" the software as it processes to try to find
            the problem.
 
 

PAGE 30


            3. BAD NUMBERS - You might find a conflict in numbers on a report, or a
            jumbled report. This may be due to circumstances in the store, or a software
            problem. Getting to the root of this type of problem is usually easier. What was
            the situation? What time was it? etc. Taking similar reports on two different
            registers can cause a problem on one or both of the reports. It is possible to take
            a report such as a 3 report and a 31 report and not have figures cross match,
            because of what was taking place on another register while the report was
            running. Example: take a 3 report which will have drawers 1-5 on it. Just as it
            prints the figures for drawer 1, the cashier on 1 totals an order. That order might
            be in the totals at the end of the report, but not in the drawer report because it
            had already been printed. The only safe way to cross check figures is when
            there are absolutely no sales or other activities being performed. Remember,
            any register can be the "master" for taking reports, but only one master at a time.
            Don't take reports on more than one register at a time.

            SUMMARY
                 In any problem situation, we need as much information about the situation as
            possible to be able to solve the problem. We also need to be notified as soon as
            possible about the problem, via your normal company procedures.
 


PAGE 31




DATA RECOVERY PROCEDURE

 



            If you have a problem with your system which requires you to reload the
            program, it is usually possible to retain the data which is already in the system.
            There are however, some rules which must be followed to avoid some potential
            problems.

            1. Hook up the Disk Loader (DL) to the master register. Small (power) plug first,
            and then the large plug (EIA Loader Port). Insert a spare ("scratch") disk in the
            loader. If this disk has never been used before it must be formatted (MODE 7).
            Follow the instructions to perform MODE 3 (dump data to disk). When through,
            remove the disk, mark it, and set aside for now.

            2. Perform a MODE 10 (clear memory program & data) . This will erase
            everything in the memory.

            3. Insert the factory program disk into loader and perform a MODE 2 (load data
            from disk) of file #1. When finished, press the GO key (the system will not react
            to this "GO"; nothing will print on the registers). Remove the disk from DL.

            4. Perform the Keystrokes on the register which wake up the machine (just as
            you would first thing in the morning,) and enter the correct date and current time,
            plus 5 minutes.

            5. Insert the disk with the data dump you just made (today's data) into the DL
            and perform a MODE 2 (load data from disk) with the correct file. When load is
            complete, press GO key, and remove disk from DL.

            6. Take some data reports and see if the data is correct, and isn't jumbled. If the
            data looks like garbage, go to step 9.

            7. If it looks OK, you need to do a few things.

                 a. Assign new cash drawer numbers to the drawers you have up front. The
             numbers you had previously assigned will not be available for the rest of the
             day, but their figures should be in the 3 report. You will be able to assign the
             "lost" numbers after the first DSR. If your system normally prevents a DSR if
             an insert is active, you must disable that function or the DSR will not run due
             to the "lost" inserts (MGR/SAYS - 17 - ENTER - OUT).
 


PAGE 32



            b. Reassign all of the buffers to activate your Expediter Printer(s).
                 c. Check that the CRTs are activated.
                 d. Check that the manager options are correct (MGR/SAYS - 506 - RPT.).
                 e. At this point the cashiers can resume normal operations.
                 f. Set the day counter to the correct day. (MGR/SAYS - 27 - ENTER)
                 g. Activate the RAIS option (if required) and perform a 41838 DELETE to
                 restart the system (don't forget to warn the cashiers about the restart).
                 h. Check the labor information for accuracy.

            8. Disconnect DL from the register. Unplug EIA plug first, and then the power
            plug. You should now be operational, with approximately the correct time in the
            system. If you need to adjust the time in the system, you must clock everyone
            out. Go to step 15.

            9. Perform a MODE 9 (clear memory, data only).

            10. Insert your original store data disk and perform a MODE 2 from the correct
            file. When finished, press GO, and remove the disk from the DL.

            11.
                 a. Prepare fresh drawers for up front, and assign their drawer numbers where
             appropriate, or do whatever is necessary to return to normal operations and
             retain cash integrity.
                 b. Reassign all of the buffers to activate your Expediter Printers.
                 c. Check that CRTs are activated.
                 d. Check that the manager options are correct (MGR - 506 - RPT.).
                 e. Check that all prices and menu items, in the data you just loaded, are up to
                 date and accurate.
                 f. At this point the cashiers can resume normal operations.
                 g. Set the day counter to the correct day. (MGR SAYS - 27 ENTER)
                 h. Activate the RAIS option (if necessary) and perform a 41838 DELETE to
                 complete a restart. (don't forget to warn the cashiers about the restart.)
                 i. Check the labor information for accuracy.

            12. Disconnect DL from the register. Unplug EIA plug first, and then the power
            plug. You should now be operational.

            13. Since you may have loaded a fairly old data dump, you should check the
            data in the system for correctness.

            14. You are finished.

STANDALONE OPERATIONAL KEYSTROKES
HOW TO GET IN AND OUT OF STAND-ALONE

            1. To enable stand-alone (which must be done at each register), press through
            the beeps: [MGR/SAYS]-[1232]-[ENTER]

NOTE: IF THERE WAS A DRAWER ASSIGNED BEFORE, THERE WILL BE A
DRAWER ASSIGNED NOW. THE SYSTEM WILL PRINT A CASH REPORT
FOR CASH RECEIVED PRIOR TO ENABLING STANDALONE.

            If no drawer was assigned the register will print STANDALONE IN, and you must
            assign a drawer using standalone keystrokes.

            2. To disable standalone (which must be done at each register, enter the
            following keystrokes: [MGR/SAYS] [1231] [ENTER] This should be done when
            the main CPU is reprogrammed and ready to operate.

NOTE: SYSTEM PRINTS CASH, DISCOUNTS AND A WORKSHEET FOR
CASH ACCRUED IN THE STANDALONE MODE. REGISTER PRINTS "S.A.
OUT".

IMPORTANT: DRAWERS ASSIGNED IN STANDALONE WILL NOT BE
RETAINED WHEN GOING BACK TO NORMAL CPU OPERATION.

            3. POLL TIC: (Terminal Interface Controller). [MGS/SAYS]-[1233]-[ENTER]

NOTE: WHEN YOU PRESS MGR/SAYS AT A REGISTER THAT WAS IN
STANDALONE IT WILL PRINT "STANDALONE ADDRESS "X" NOT POLLED.
ENTER THE FOLLOWING KEYSTROKES: [MGR /SAYS]-[1233]-[ENTER]

            The register will print POLL COMPLETE. The CPU now knows the amount of
            cash earned while in stand-alone, and reports it in the DSR.
 


OPERATIONAL KEYSTROKES

                 1. To assign a cash drawer [MGR/SAYS] [OPER A] [IN]
                 2. To de-assign a cash drawer [MGR/SAYS] [OPER A] [-OUT]
                 3. To obtain a product mix report (this is a very long report)
                  [MGR/SAYS] [REPORT] [1] [ENTER]
                 4. To enable a duplicate ticket (Duplicate prints in red after change)
                 [MGR/SAYS]-[OPER-A]-[ENTER]
                 5. To disable the duplicate feature [MGR/SAYS] [OPER A] [ENTER)
 


PAGE 34




WHAT IS STANDALONE?

 


            STANDALONE is a 16k backup memory available in each Mark IV register. The
            backup memory consistently updates the cash transactions at each register. In
            case of an unexpected loss of program, you will still have a register at your
            disposal until you get the main CPU reprogrammed. ALSO: The cash report
            while in standalone will show any cash accrued at the register prior to entering
            standalone.

            IMPORTANT: In order to make standalone available in case of program loss
            YOU MUST PROGRAM THE STANDALONE MEMORY IN EACH REGISTER
            WHILE THE SYSTEM IS FULLY OPERATIONAL. This process is best done
            before opening on each day.

            TO PROGRAM STANDALONE for each register, go to EACH register and press:
            [MGR SAYS] - [1237] - [ENTER].

            This takes about twenty seconds, and will program your backup memory.

COMMENTS ON STANDALONE


 



            A. During standalone operations, all words appearing on the receipts will contain
            a maximum of six characters only.

            B. CRT monitors will not function in standalone. Call orders verbally.

            C. Extra ingredients will not price. Use the PLUS CENT key to charge the
            appropriate price.

            D. DINE, TOGO, CAR destinations are descriptors only. You MUST press
            "TOTAL" to complete each order.

            E. Change key is required. You may only make change once.

            F. To discount an order you must press the number value and the discount key.
            EXAMPLE: [Hamburg] [Diet] [TOGO] [50] [DISC] [TOTAL].

            G. There are no DSRs while in stand-alone.

            H. There is no Wake up routine while in standalone.

            I. Voids must be taken out manually.

            J. While in standalone, all cash totals per register are accumulative.

            K. Just because one register will not go into standalone does not mean that the
            others will not. TRY THEM ALL!!!

            L. REMEMBER, each unit is working independently.

THE FASFAX SELF-TEST PROCEDURE

 


            The FASFAX Mark IV has a "SELF-TEST" routine that is sometimes useful in
            troubleshooting. The "self-test" assumes that the TIC (Terminal Interface
            Controller) will be taken "Off line" while performing the tests. If not, all registers
            downline from the unit placed in "Self test" will be unable to communicate back
            to the Master (CPU) register. To take a satellite "Off line" simply disconnect the
            Blue line (TWINAX) connected to the TIC and plug them into each other.

            (1) The TIC Must be OFF-LINE while in the SELF-TEST MODE! Remove all
            TWINAX cables between the Male/Female TWINAX connectors and connect the
            two connectors together.

            Put the TIC in the SELF-TEST mode.

            Move the TEST/OPERATE TOGGLE SWITCH to the middle or forward position.
            (a) Insure the display reads SELF-TEST
            (b) that the SELF-TEST L.E.D. is on.

            (2) TEST SELECTING
            Rotate the ADDRESS/TEST SELECT rotary switch to the desired number
            corresponding to the desired test.

            ( 3 ) TEST STARTING
            Once you have set the ADDRESS/TEST SELECT rotary switch to the desired
            TEST number, push the START-STOP/FEED momentary contact Push button
            once and check the following:
            (a) the RUN LED on the TIC is on and
            (b) the TEST starts.

            NOTE: that on any given TEST, you must STOP before a new TEST can be started.3
 


PAGE 36



            (4) TEST STOPPING
            When you have completed the desired TEST, push the START-STOP/FEED
            momentary push button switch once again. Check the following:
            (a) the TEST did stop and
            (b) the RUN LED on the TIC is off.

            (5) NEXT TEST
            To START another TEST you must follow the instructions; set down in ( 2 )
            above.

            TEST ONE (1) Verifies that all LED's on the TIC are working.

            TEST TWO (2) This test verifies the functionality of the ADDRESS/TEST
            SELECT rotary switch to act not only as a TEST SELECT device but also as an
            ADDRESSING device in the OPERATE MODE.

            TEST THREE (3) This test verifies that all segments of the 10 digit display
            (BOTH CUSTOMER/OPERATOR), and the character generator chip are
            functioning properly.

            TEST FOUR (4) This tests the operation of a 110 key keyboard. Only used in
            110 keyboard.

            TEST FIVE (5) This test verifies a signal is getting to the left cash drawer if used
            by opening the left cash drawer.

            TEST SIX (6) This test verifies a signal is getting to the right cash drawer if used
            by opening the right cash drawer.

            TEST SEVEN (7) This test verifies the following dot matrix printer functions
            (a) Quality of printed characters
            (b) Ribbon advance
            (c ) Ribbon change from black to red ( if used )
            (d) Paper take up
            (e) Paper feed


PAGE 37



            Start this test and visually check, while printing the alphabet, all the above functions.

            TEST EIGHT (8) This test verifies the TAB Printer and is not used in a Burger King Operation

            TEST NINE (9) This test verifies that the piece of TWINAX (Blue line cable) is T.I.C. If the TWINAX
            is good, you   will get the RUN LED and SELF TEST only. If bad, the FAIL LED will also light.

            TEST TEN (10) This test shows the generation date or code of the EPROM. The date will be displayed in
            the with the  enhanced (162 key) keyboard.

            TEST ELEVEN (11) This test verifies that the paper out sensor is functioning. Removing the PAPER ROLL
            will cause the FAIL LED light to come on.

            TEST TWELVE (12) This test verifies the COIN CHANGER A .

            TEST THIRTEEN (13) This test verifies the COIN CHANGER B.

            TEST FOURTEEN (14) This test verifies the enhanced keyboard (162 keys). It causes the keyboard buzzer
            to sound a long audible tone. When used with the manager overlay (alpha-numeric), pressing the keys will
            cause the display to show the key number corresponding to the key pressed. This test is valuable in determining
            whether the Keyboard Membrane or the Logic Board attached is the defective part. The Keyboard LED on
            the TIC should light when ANY key on the keyboard is pressed.

            TEST FIFTEEN (15) Is currently not a FASFAX supported test.
