4.2.10 Analog matrix to panel wiring
The analog audio RS-422 data communications module uses a 4-pair wiring
scheme between the matrix and panels. This module requires an MVX-A16 card
in the matrix.
Four-pair analog wiring is wired with shielded CAT5 RJ-45 cable:
Pair 1 transmits analog audio from the matrix port to the panel.
Pair 2 transmits RS-422 data from the panel back to the matrix card
port.
Pair 3 transmits analog audio from the panel to the matrix card port.
Pair 4 transmits RS-422 data from the matrix port back to the panel.
