Question:  I have recently purchased a Helixnet system with two HLI-2W2 Modules. I am trying to get analog clear com format out of the 2 wire
Into a Telex BTR 800 unit. Do you have any advice on this topic?
Answer:  The HelixNet 2W module and BTR-800 2W interface both require a Clear-Com party-line power supply (PS-702 or PS-704) or main station connection (MS-702 or MS-704) to provide the 30 Vdc for the HelixNet and BTR interfaces and to provide the 200 ohm termination for the PL channel.  This information also applies to the Clear-Com WBS-670 and WBS-680 wireless intercom base stations.  Attached below is a picture of a typical setup between the HelixNet base with a 2W module to a WBS-680 / BTR-800 wireless base station.
