WIRING
i-Series intercom panels use a twisted 4-pair transmission scheme to
connect them to the matrix frame using the industry standard RJ-45
connector. Refer to Installing an Eclipse Matrix System: An Overview
for connector installation and use, and the type of cable needed for
connection between panels and frames.
Each pair of the twisted 4-pair wire has the following function:
• Pair 1 transmits analog audio from the matrix port to the panel.
• Pair 2 transmits digital data from the panel back to the matrix card
port.
• Pair 3 transmits audio from the panel to the matrix card port.
• Pair 4 transmits digital data from the matrix port back to the panel.
