Pump Programming
Configuring the 9800 Series
Electronic Totalizers
(JP7 on M06333KXXXX CPU and SW1-7 on Previous CPU)
This jumper/switch should be open for normal operation (electronic totals protected). When
jumpered (closed), this allows the electronic totals to be reset.

Pump Disable Detection
(JP8 on M06333KXXXX CPU. SW1-8 on Previous CPU)
This jumper/switch allows the pump/dispenser to detect or ignore a pump disable (RS-485
protocol break character). When detection is enabled, the pump/dispenser will monitor the RS-
485 communications for a protocol break character. When received, any transition in progress
will be halted and then completed. This setting should only be used when the pump/dispenser
is communicating to a Gasboy CFN system. When communicating to a Gasboy TopKAT
™
system, or when in Standalone mode including Pulse-out I/F configurations, the setting should
be disabled (see below).

JP9
(Only on M06333KXXXX CPU)
JP9 is a spare jump jack and is not used.
The M06333KXXXX CPU board can also be configured for various operating conditions
using the switch positions SW2-1 through SW2-10. The previous CPU only uses SW2-1
through SW2-4. Check these switches and change if necessary. Switch settings must be
changed with the power to the pump/dispenser “Off”. The 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
(Identical for M06333KXXXX CPU and Previous CPU)
These four switches serve a dual purpose: as an address setting when communicating via RS-
485 I/F (for example, Online mode with CFN systems, TopKAT Electronic System or Islander
II System), or as a pulser output rate selector when in Pulse-out I/F configuration (for
example, Gasboy Series 1000 Fuel Management System).
Address Switches (if JP2 on M06333KXXXX CPU or SW1-2 on Previous CPU is Open)
A unique address identifier must be set when the pump/dispenser is communicating via the
RS-485 interface. The unique address must correspond to the address of a unique PCU of a
Gasboy CFN, Islander II, or TopKAT Electronic system. There are 16 possible address
combinations; up to 16 pumps (single or twin) can be connected via the RS-485 interface.
Addressing should 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.
