Pump/Remote Dispenser Operation
SW2
This four-position switch pack serves a dual purpose: as an address setting when
communicating on the Gasboy RS-485 loop or TopKAT, or as a pulser output rate selector
when pulser data is sent to a Fuel Management System other than a Gasboy CFN or TopKAT.
Address Switches
A unique address identifier must be set when the 9800Q is connected to the Gasboy RS-485
pump loop via the 9800Q RS-485 I/F PCB. Because there are 16 possible address
combinations, up to 16 units (single or twin) may be connected to the pump loop. 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 unit on the RS-485 loop does not have to
be address 1. The chart at right gives the switch settings and address selections. With the
TopKAT option, the address must be set to 1.

Pulser Output Rate Switches
When the 9800Q is connected to external control equipment other than a Gasboy CFN system
(standalone), the pulser signals are sent out via the 9800Q Pump I/F PCB. The pulse rate
required by the monitoring equipment can be configured by setting the switches as shown in
the chart below. The pulse rate represents pulses per gallon (PPG, US Gallons and Imperial
Gallons) or pulses per liter (PPL, international). For US Gallons or Imperial Gallons
configurations, the pulse rate can be up to 100 PPG for the 9850Q and 500 PPG for all other
models. For Liters configurations, the pulse rate can be up to 10 PPL for the 9850Q and 100
PPL for all other models. This switch may need to be sealed by a Weights and Measures paper
seal if the 9800Q is used for the resale of product.
