Switches Postpay-Prepay Console II
The following switches apply only to the postpay-prepay console II. The version of software on
the CPU PCB determines if the console is a P-P I or a P-P II.
SW1 - Reset Switch P-P II
The Reset switch starts a hardware and software reset of
the CPU PCB. The SW2 and SW3 switch settings are
read when a reset occurs (and at power up). This switch
should be pressed whenever switch settings are
changed.
SW2 - Address Switches P-P II
An address must be set to identify the console when it
is connected to the GASBOY CFN Series Fuel
Management System. This address is a unique
identifier if two postpay-prepay consoles are connected
on the same RS-422 line. The physical wiring order
does not have to correspond with the address order,
that is, the first console on the RS-422 line does not
have to be address 1.
