IMF-3 Interface Module Frame Wiring
To Matrix
To connect the GPI-6 to the matrix, plug one end of an RJ-45 cable
(eight wires with no reversal) into the GPI/RLY INTERFACE connector
on the back of the matrix. Plug the other end into the top RJ-45 (CH. A
MATRIX) connector for the GPI-6.
To connect an additional GPI-6 interface, plug one end of a short
RJ-45 cable into the lower RJ-45 (CH. B MATRIX) for the first GPI-6.
Then, plug the other end into the top RJ-45 (CH. A MATRIX) connector
for the additional GPI-6.
Additional GPI-6 interfaces are added in the same way, using
"daisy-chain" wiring. If there are multiple GPI-6 interfaces, 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.
For Eclipse systems if both GPI-6 and RLY-6 interfaces are used the
GPI-6 interfaces are required to be placed first in the daisy chain (see
Figure 4-9).
The maximum combined length of all the RJ-45 cables should not
exceed 20 ft. (6 m).
To External Device
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
10 shows the pin assignment of these connectors as viewed from the
matrix side of the connector.
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 4-11, the labels on the pins
apply to either connector.
