IP Heavy Duty Connections

The IP Heavy Duty Stations

Main connectors

To access these connectors the frontplate must be removed.

LAN	10/100 Mbps RJ-45 port for LAN (uplink) connection. Supports PoE (802.3af). Draws power from either spare line or signal line.
AUX	10/100 Mbps RJ-45 ports for auxiliary equipment such as PC and IP camera.
Input/Output	Pluggable screw terminal
Local Power	Plugable screw terminal, 19-27 VDC Idle 4W, max. 8W

Power Supply

The IP Heavy Duty Station supports Power over Ethernet (PoE, IEEE 802.3 a-f) where power can be drawn from either the spare line or signal line.

If PoE is not available, the IP Substation can be connected to a 24 VDC local power supply.

Network Connection

There are two RJ45 ports on the IP Heavy Duty stations:

• LAN port (P1): for connecting to the network and the AlphaCom XE Audio Server.
• AUX port (P2): for connecting to auxiliary equipment such as a PC or IP Camera.

Input/Output Connections

There are I/O connection options for all IP Substations. These I/O connections include:

• 3 digital inputs (P4):

Input 1 = PTT from headset, and for restoring factory default

Input 2 = Call button no.2 or logical input (optional)

Input 3 = Hookswitch

• 1 relay output (P3)
• 1 logical output (TP9)
• 1 Line out (TP1/2): Audio output to handset speaker (0dBm 600ohm balanced)

Connections

There are four connectors on the IP heavy Duty station PCB: P1-P4.

• P1 RJ45 LAN port is for connecting to the data network

• P2: RJ45 AUX port is for connecting to auxiliary equipment such as a PC

• P3: 6-pin plug-on screw terminal for external connections.
  • Pin 1/2: Connection of external 8 ohm loudspeaker (optional).
  • Pin 3/4: Internal NO relay contact for additional call indication, etc.
  • Pin 5/6: Connect 24VDC power supply if PoE is not used

• P4: 6-pin plug-on screw terminal for internal connections.
  • Pin 1/4: Input for PTT from headset and restoring Factory Default Setting.
  • Pin 2/4: Call button no. 2 or logical input (optional).
  • Pin 3/4: Connected to hook-switch (reed-switch)
  • Pin 5/6: Station LED for call and message info. (Pin 6 is positive.)

• TP1/2: Audio output to handset speaker (0 dB, 600 ohm balanced).
