4-Pair Analog
Four-pair analog wiring is done with shielded CAT5 RJ-45 cable.
• Pair 1 transmits analog audio from the matrix to the panel.
• Pair 2 transmits digital data from the panel back to the matrix.
• Pair 3 transmits audio from the panel to the matrix.
• Pair 4 transmits digital data from the matrix back to the panel
