GPI-6 INTERFACE WIRING
The GPI-6 input interface module provides connection of six
programmable inputs to the matrix so that each input can control a
predefined matrix function. Multiple GPI-6 interfaces can be
daisy-chained to provide connection of up to 60 inputs to the matrix.
RLY-6 and GPI-6 modules can be mixed together up to the total limit of
60 items. Five RLY-6 and five GPI-6 modules would provide 30 relays
and 30 inputs for a total of 60 inputs and outputs.
Note: For Eclipse systems if both GPI-6 and RLY-6 interfaces are
used the GPI-6 interfaces must be placed first in the daisy
chain.
This restriction does not apply to Matrix Plus 3 systems where
interfaces can be mixed in this 'daisy-chained' scheme.
IMF-3 Interface Module Frame Wiring
To Matrix Frame
To connect the GPI-6 to the matrix frame, plug one end of an RJ-45
cable (eight wires with no reversal) into the GPI/RLY INTERFACE
connector on the back of the frame. 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-6s 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). Refer to Figure 4-19 on page 1-27.
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
4-21 shows the pin assignment of these connectors as viewed from
the frame side of the connector.
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 4-21, the labels on the pins apply to either
connector.
