The built-in relays in the IP Heavy Duty telephone is controlled by the RCO command in the event handler.

To map the relays of the IP Station to logical RCO's, select Exchange & System -> RCO. Pick a free RCO, select Change and set the RCO Type = Station, enter the physical number of the IP Station, and set pin number = 7 (8 for the second relay).

The relay of IP Station 144 is mapped to RCO 10.

In Users & Stations, select the IP Heavy Duty telephone from the list box, then press Events, and Insert a new event with the following properties. This will cause the relay to operate during the ringing of an incoming call.

When station 144 receives a call in private ringing mode, RCO 10 will be operated. This will again operate the relay and the rotary light.

Note: The internal ringer device is not in use. The reason is that the housing of the IP telephones are also used in analog versions of the telephone, connected to regular 2-wire telephones lines. Then the ringer is operated by the ringing voltage from the telephone exchange. Although the ringer device is not in use in the IP Heavy Duty station, it has not been removed as it would jeopardize the IP rating of the station.
