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. This
restriction does not apply to Matrix Plus 3 systems where interfaces
can be mixed in this 'daisy-chained' scheme.
The maximum combined length of all the RJ-45 cables should not
exceed 20 feet (6 meters). Figure 2-1 shows an example of
“daisy-chain” wiring.

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
2-2 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 1-3
are available on that connector. The connector labeled CH.A I/O has
