13.7.4 Two-wire and control connection to radio system
The two-wire connection uses a TW-47 radio interface. Because this has no power supply,
you must use an Encore Main Station to supply power. You can also use an alternative source
of power, such as a PK-7, PS-702 or PS-704.
The diagram in Figure 13-12 shows a system using an Encore Main Station.
To connect the HelixNet Partyline to a radio system using two-wire:
1) Connect the HelixNet Partyline to the Encore Main Station. For details, see 13.1
Connecting HelixNet Partyline to Encore®.
2) In the Modules Settings menu, select Slot n/Port A/B 2W > Channel Assign >
Channel # to assign the 2W port to a Channel, for example Channel A.
3) Connect the Encore Main Station to the TW-47 radio interface.
4) Connect the TW-47 radio interface to the radio basestation.
