To Matrix
To connect the RLY-6 interface 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 RLY-6.
To connect an additional RLY-6 interface, plug one end of a short
RJ-45 cable into the lower RJ-45 (CH. B MATRIX) for the first RLY-6.
Then, plug the other end into the top RJ-45 (CH. A MATRIX) connector
for the additional RLY-6.
Additional RLY-6 interfaces are added in the same way, using
"daisy-chain" wiring. If there are multiple RLY-6 interfaces, the inputs
in the first interface are numbered 1 to 6 for RLY 1; in the second
interface 1 to 6 for RLY 2, etc. RLY interface 0 is the internal Matrix
RLY 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 below).
The maximum combined length of all the RJ-45 cables should not
exceed 20 ft. (6 m).
