6. TROUBLESHOOTING GUIDE
Many problems that appear to be the result of a defective computer are really caused by contami-
nation of the computer memory. Prior to replacing the computer for a first occurrence of a
particular problem, a RAM clear should be initiated and the computer retested. If the computer
functions, it should not be replaced unless a second occurrence of the same problem results.
To clear the RAM on the Duplex II computer use the following procedure:
•
Record all totals and all option programming.
•
Remove power from the computer by disconnecting the J3 connector.
•
Short pins 3 and 5 on the J6 connector while replacing the J3 connector on the computer.
(Pin 1, on the J6 connector, is closest to the center of the printed circuit board.)
•
Remove the short from the J6 connector.
•
Enter option 97, the money display will show XXXAB. (XXXAB represents a number up to
5 digits.)
•
Enter AB as BA. For instance, if 91 is shown in the two least significant digits of the money
display enter 19. (AB represents the two least significant digits in the money display.)
•
Press and hold the price jog switch until zeros appear in the money and unit price displays;
this indicates that the RAM has been cleared.
•
Reset the fueling point if applicable, all option programming, and unit prices. J6 pins 3 and 5
must be jumpered and the power cycled before options 2, 4, or 97 may be changed.
•
Record all totals a second time and give them to the dealer/manager for his/her records.
Warning:
The above and following actions require that the electrical power to the equip-
ment be on. Remember that electrical power is dangerous and proper precau-
tions to protect oneself from contact with the electrical power are necessary.
