Connections

IP Substation Main Board 1.PNG

LAN port P1 & AUX port P2

P1:

RJ45 LAN connector for 10/100 Mbit Ethernet connection. The station can be powered from this connection if the line supports Power over Ethernet (PoE).

P2:

RJ45 connector for auxiliary equipment like IP camera, PC or a second IP station. This port does not have an individual IP address. It does not carry power for auxiliary equipment.

P1/P2


P3 - External Loudspeaker, Relay Output and External Power Input

P3


6-pin plug-on screw terminal for external connections.

  • Pin 1/2: Connected to station loudspeaker. May also be used for 8-20 ohm / 2W external loudspeaker in parallel.
  • Pin 3/4: Internal NO (Normally Open) relay contact for door lock control, etc. Contact rating: Current: max 1A. Voltage: max 60 VDC. Power: max 30 W DC.
  • Pin 5/6: Connected to 24 VDC for station power when power is not distributed via LAN. Pin 6 is positive.

About the relay: The relay actually has a change-over contact. On the screw terminal you have NO (Normal Open) contact only, but NC (Normal Closed) contact is also available between connector P3 - pin 4 and the soldering pad TP7.

P4 - Inputs and Station LED

6-pin plug-on screw terminal for internal connections.

P4


  • Pin 1/4: Call button no. 1
  • Pin 2/4: Call button no. 2 or logical input
  • Pin 3/4: Call button no. 3 or logical input
  • Pin 5/6: Station LED for call and message information

TP1/TP2 - Line Output

0 dB, 600 ohm balanced audio output for connection to a power amplifier.

Note:

The amplifier input MUST BE AN AC COUPLED INPUT (transformer, capacitors, etc.).


TP9 - Output

Logical output for a spare relay driver, max. 30 mA.

Additional DAK-keys, M- and C-key

The IP substation board supports input for digits 0 - 9, 10 DAK-keys, as well as M-key and C-key. The inputs are available on soldering pads on the substation PCB.

DAK 7:  N105 + N113
DAK 8:  N105 + N114
DAK 9:  N105 + N115
DAK 10: N106 + N110
-------------------
M-key:  N115 + N111
C-key:  N115 + N110


Inputs for digit keys

If more than 10 DAK keys are needed, it is possible to use the digit keys as DAK keys. The function needs to be enabled by the flag "Digit Key is DAK" in the Users & Stations > Station Type menu in AlphaPro. The regular DAK keys are then moved to DAK 11 - 20.

Digit 0:  N111 + N110
Digit 1:  N112 + N110
Digit 2:  N112 + N111
Digit 3:  N113 + N110
Digit 4:  N113 + N111
Digit 5:  N113 + N112
Digit 6:  N114 + N110
Digit 7:  N114 + N111
Digit 8:  N114 + N112
Digit 9:  N114 + N113
