Two RJ-45 Ethernet terminals on the IP filter board are used for IP LAN and WAN communication

Analogue Intercom Stations

The two-pair star wired intercom cables are connected to connection boards on the cabinet DIN rail or in a separate distribution field

Program Input

6 program distribution sources can be connected to the APC board via an optional program connection board. Up to 64 extra programs may be added using AGA boards with 16 programs per board

Serial Ports

The serial ports with RS232 and RS422/RS485 interfaces are used for connecting to equipment using these protocols


Serial Port 0

RJ45 (RS232 Only)

No additional settings necessary

Serial Port 1

RJ45 (RS232/422/485)

Additional settings:
  • Switch 8 on S601 on the AMC-IP board must be set to ON.
  • Use the two jumpers on the AMC-IP Filterboard to select between RS422 and RS485.

Remote Control Inputs (RCI)


The optional program connection board has input for 6 Remote Control Inputs (RCI) which can initiate programmed actions

RCI inputs in an AlphaCom XE20 and XE26


In AlphaPro there is an RCI table, where the physical address of the input is entered, along with the desired actions. The physical address is given as device + pin-number.

The RCI table supports up to 140 inputs.

  • For internal RCIs in the AlphaCom XE1, the device address is 68, and the pin number is 1-6.
  • Internal pin number 8 is the temperature alarm
  • Mappings for the internal RCI's are autoloaded. Mappings for external RCI's (Slave modules, RIO's or IPARIO) must be manually programmed.

Cold start procedure

Cold start to load default factory settings
  • Press the reset button on the APC board briefly while keeping the cold start button pressed.
  • Keep the cold start button pressed at least 2 sec. after power on. The AMC status LED will blink green when the boot is ready.

Cold-start of AMC application only, keep IP setting

Modify Factory Default Settings

After cold start the system is set up with a default program and is working without any further programming. To change or add to the default settings, the AlphaPro programming tool must be used.

Other methods of factory default

A factory default can also be achieved in other ways:

  • From AlphaWeb: System Maintenance -> System Recovery -> Load Factory Defaults
  • From AlphaPro: Upload a default AlphaPro database to the exchange
