Installing Atlas 9800 CPU Board (M06333KXXXX)
JP7 - Electronic Totalizers
This jumper must be open for normal operation (electronic totals protected). When jumpered,
this allows the electronic totals to be reset.

JP8 - Pump Disable Detection
This jumper allows the pump/dispenser to detect or ignore a pump disable (RS-485 break
character). When detection is enabled, the pump/dispenser will monitor the RS-485
communications for a pump disable signal. When received, any transition in progress will be
halted and then completed. This setting must only be used when the pump/dispenser is
communicating to a Gasboy Cash Flow Network (CFN) System. This setting must be disabled
(jumpered) for all other configurations (for example, Gasboy TopKAT or Standalone).

JP9
This jumper is spare and not in use.
9 CPU Board (M06333KXXXX) can also be configured for various operating conditions using
the switch positions SW2-1 through SW2-10. Check these switches and change, if required.
Switch settings must be changed with the power to the pump/dispenser “Off”. CPU Board
only reads new switch settings during power up.
Note: A switch in the Closed position indicates that the switch is “On” (towards the center of
the CPU Board).
SW2-1 through SW2-4
These four switches serve a dual purpose: as an address setting when communicating through
RS-485 I/F (for example, Gasboy CFN systems), or as a pulser output rate selector when in
Pulse-out I/F configuration (for example, Gasboy Series 1000 FMS).
Address Switches (if JP2 is Open)
A unique address identifier must be set when the pump/dispenser is communicating through
RS-485 I/F. The unique address must correspond to the address of a unique Pump Control Unit
(PCU) configured in a Gasboy CFN or TopKAT system. There are 16 possible address
combinations and up to 16 pumps (single or twin) can be connected through the RS-485 I/F.
Addressing must start at 1 and continue sequentially through 16. The physical wiring order
does not have to correspond with the address order; that is, the first pump/dispenser on the

RS-485 does not have to be address 1.
