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 transaction in progress will be
halted and then completed. This setting must be used only when the pump/dispenser is
communicating to a Gasboy Fuel Controller using RS-485 Communications. This setting must
be disabled (jumper installed) for all other configurations.
