prevent personal injury, ensure power is removed by turning off the circuit breaker for the Master FMU
and each connected dispenser.

circuit breaker panel.
3. Unlock and open the Master FMU upper cabinet and pedestal access doors.
4. Remove both electrical access covers in the pedestal.
NOTE
There are several variations of the I/O Silver Board. If an I/O Silver Board was previously installed for
another application, verify compatibility for Satellite communications: an unused receptacle and connector
in any position JP1 through JP8 for RS-422, and a ribbon cable receptacle in corresponding positions JP9
and/or JP10 are needed for Master FMU/EIU communications.
5. An I/O Silver Board must be installed in the Master FMU, and contain the appropriate number of
connectors JP1 through JP8, and 5-pin terminal plugs, to make the required Master FMU-EIU RS-422
cable connections. Perform the following to install an I/O Silver Board, or remove and replace an
existing I/O Silver Board:
a. If an existing I/O Silver Board is installed and is not compatible with the EIU interface, perform the
following to remove the I/O Silver Board:
1) Note the locations and disconnect all ribbon cables and plugs from the existing I/O Silver
Board.
2) Remove the existing I/O Silver Board mounted over the Pedestal I/O Board on six
standoffs.
b. If an existing I/O Silver Board is not installed, remove six screws from the Pedestal I/O Board
(above and below TB1, TB2, and TB3, see Figure 4-6) and install six aluminum standoffs.
c. Position the new I/O Silver Board over the Pedestal I/O Board, and attach to the standoffs with six
screws.
d. Reconnect any ribbon cables and plugs removed from a previously installed I/O Silver Board.
6. Select an unused receptacle, JP1 through JP8, to receive the Master FMU/EIU communications cable
connection.
7. As required, attach one end of the 20-pin ribbon cable to the applicable I/O Silver Board receptacle
JP9 or JP10:
a. If a receptacle in position JP1 through JP4 is to be used, the ribbon cable connector should be
plugged into JP9.
b. If a receptacle in position JP5 through JP8 is to be used, the ribbon cable connector should be
plugged into JP10.
8. If applicable, route the other end of the Satellite Ribbon Cable up through the Cabinet bulkhead thru-
hole and connect the 20-pin connector to J5 or J6 on the Satellite - I/O Control Board:
a. If the ribbon cable is connected to JP9 on the I/O Silver Board, connect the other end to J6 on
the Satellite - I/O Control Board.
b. If the ribbon cable is connected to JP10 on the I/O Silver Board, connect the other end to J5 on
the Satellite - I/O Control Board.
