Upgrading to BRCM2.x
Connecting Field Wiring
There are multiple 8-to-8 pin connectors supplied that connect the field wiring board to the
D-Box boards. Use of these connectors will vary if one D-Box board is used for
dispenser/pump and the other board is used for CRIND (see
on
To connect the field wiring board to the D-Box boards, proceed as follows:
1
If the box is part number PA04222000202/202B/002B (for being used with dedicated wiring),
proceed to step
. If the D-Box connects to a Passport POS, connect all supplied connectors
between the top of the M14881A001 Printed Circuit Assembly (PCA) Field Wiring Board and
the D-Box board(s).
~OR~
If the D-Box connects to a non-Passport POS and there are multiple D-Box boards, only
connect the top of the M14881A002 PCA Field Wiring Board to the D-Box board
communicating to the dispenser/pump current loop.
2
Connect the field wiring connectors to the M14881A002 PCA Field Wiring Board
(see
).
For non-Passport POS with dispenser/pump and CRIND connected communications in the
same D-Box, connect the dispenser/pump field wiring connections to the bottom of the field
wiring board and connect the CRIND communication wires to the D-Box board.
~OR~
Connect all field wiring connectors to the bottom of the field wiring board.
After this operation, all dispenser/pump communication are connected either directly to the
field wiring board or to a D-Box board via the M14881A002 PCA Field Wiring Board.
Note: All dispensers that have the DCM2.x board, have either the pump or CRIND connected
to the field wiring board to receive the high-speed signal. A generic CRIND or a Legacy
dispenser connects directly to the D-Box board because these configurations cannot
accept the high-speed signal.
3
Hold the lid assembly close to the D-Box [the lock plate has two tabs to allow the lid assembly
to rest on the tabs (see
)] and connect the lid cables to the P400 and P416 connectors
between the lid assembly and the M14881A002 PCA Field Wiring Board
(see
on
