ANALOG MATRIX FRAME TO PANEL WIRING
The analog audio RS-422 data communications module (COM-10)
uses a 4-pair wiring scheme between the frame and panels. This
module requires an MVX-A16 card in the frame.
Although some Matrix Panels have a DB-15M (male) connector for
connection to the Matrix frame, most have a built-in RJ-45 connector.
For those panels with a DB-15 male connector, Vitec Group
Communications provides a properly wired DB-15F (female) to RJ-45
adapter for direct connection with RJ-45 terminated cables.
Additionally, panels configured for digital communication are equipped
with a BNC.
Four-pair analog wiring is typically 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.
