IP Substation Board Connection

Station Board Connections There are four connectors on the IP substation board, P1-P4. P1: RJ45 connector for LAN connection. The station can be powered from this connection if the line supports Power over Ethernet. P2: RJ45 connector for auxiliary LAN equipment like TV camera, PC or a second IP station. This port has not an individual IP address or power for aux equipment. P3: 6-pin plug-on screw terminal for external connections. Pin 1/2: Connect 24 VDC for station power if power is not distributed via LAN. Pin 1 is positive. Pin 3/4: Internal NO relay contact for door lock control etc. Pin 5/6: Normally connected to station loudspeaker. May be used for 16-20 ohm/2 W external loudspeaker in parallel. P4: 6-pin plug-on screw terminal for internal connections. Pin 1/4: Call button no.1. Pin 2/4: Call button no.2 if included Pin 3/4: Call button no.3 if included Pin 5/6: Station LED for call and message info. TP1/2: Optional external audio output. This is a 0 dB, 600 ohm balanced output for connection to a power amplifier. Note that the amplifier input MUST HAVE AN INSULATED INPUT (trafo, capacitors, etc.).
