GPI-6 interface module in an IMF-3 interface frame
To connect the GPI-6 interface module to the matrix:
1. Connect the RJ-45 cable (eight wires with no reversal) to the
GPI/RLY INTERFACE connector on the back of the matrix.
2. Connect the other end of the RJ-45 cable 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 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, the inputs in the first interface are numbered 1 to 6 for GPI
1; in the second interface 1 to 6 for GPI 2, etc. GPI interface 0 is the internal matrix GPI
interface.
Note:
If both GPI-6 and RLY-6 interface modules are used, you must place the GPI-6 interface
modules first in the daisy chain (see Figure 11: RLY-6/GPI-6Daisy Chain Connection). The
maximum combined length of all the RJ-45 cables should not exceed 20 ft. (6 m).
Connecting external devices to the GPI-6 interface
To connect external devices to the GPI-6 interface, use the two DB-9M connectors on the rear
cable assembly panel for the interface.
If a DB-9F is plugged into the connector labeled CH. A I/O, inputs 1 through 3 are available on
that connector. The connector labeled CH. B I/O has inputs 4 through 6.
In Figure 13: GPI-6 interface DB-9M connector pinout, the labels on the pins apply to either
connector.
