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.
