Field Communication Wiring
Depending on the dispenser type and whether or not it has factory-installed conduit, there are different
specifications in the current loop wiring for generic or MOC configurations.
Considerations
• P300 is the current loop input for both the pump and the CRIND.
• P303 is the current loop output to the pump. It must be used even in the Generic CRIND mode.
• J3 ON enables the high-speed connection. If the high-speed connection is being transmitted on the
current loop, it only connects through the red/yellow wires. If it is on, the J304A and J304B are
disabled.
• J4 ON configures the board for Passport®, OFF for Generic CRIND mode.
Wiring Requirements
For Passport
• CRIND two-wire must be on the red/yellow wires. This is significantly different than previous CRINDs
for ensuring high-speed connection.
• J4 must be ON.
• If high-speed connectivity is used, J3 must be ON.
• The pump two-wire input must be connected to P303.
If you are using two-wire connection, refer to

Note: Do not use BRCM in passthrough mode with a Fuel Controller. Use D-Box instead.
