Wiring the GPI-6 to the IMF-3 interface frame
To connect the GPI-6 to the matrix frame:
1. Connect one end of an RJ-45 cable (eight wires with no reversal) into the
GPI/RLY INTERFACE connector on the back of the frame.
2. Connect the other end into the top RJ-45 (CH. A MATRIX) connector for the GPI-6.
To connect an additional GPI-6 Interface module:
1. Connect one end of a short RJ-45 cable into the lower RJ-45 (CH. B MATRIX) for
the first GPI-6.
2. Connect the other end of the cable into the top RJ-45 (CH. A MATRIX) connector for
the additional GPI-6.
Additional GPI-6 Interface modules are added in the same way, using daisy-chain wiring. If
there are multiple GPI-6 modules used, the inputs in the first will be numbered 1 to 6, second
will be 7 to 12, etc.
RLY-6 modules can be mixed in this daisy-chained scheme. The maximum combined length
of all the RJ-45 cables should not exceed 20 ft. (6 m).
Wiring the GPI-6 to external devices
To connect external devices to the GPI-6 interface, use the two DB-9M connectors on the
rear cable assembly panel for the interface.
Figure 24: GPI-6 interface DB-9M connector pinout shows the pin assignment of these
connectors as viewed from the frame side of the connector.
Note:
If a DB-9F is plugged into the connector labeled CH. A I/O, inputs 1 to 3 are available on that
connector.
The connector labeled CH. B I/O has inputs 4 to 6. In
Figure 27: GPI-6 interface DB-9M connector pinout , the labels on the pins apply to either
connector.
