Helixnet : HLI-2W2 2-wire interface module information / pin outs
The HLI-2W2 (2wire interface) module allows the user to interface into a analog 2-wire party-line system such as Clear-Com or RTS.
The 2wire interface module does not supply +30Vdc, this voltage must be fed from an analog Party-line main station or power supply.
The HLI-2W2 interface module does not supply a termination, this is supplied by the analog Party-line main station or power supply.
Note: If the user is interfacing an RTS 2-channel party-line system into the HLI-2W2 module the two channels are split up between the A and B connectors on the HLI-2W2 module.
