HLI-2W2

With the HelixNet Firmware Release 4.2, the HelixNet Plug-and-Go IP Intercom System now has the elastic capacity to add stations dynamically without system interruption, hardware, or software pre-configuration. This update also enhances talker identification, allowing visual indication of active talkers on channels and selective tagging of important talkers with an automatic call signal, in addition to additional user station administrative functionality.

The HelixNet HLI-2W2 is a dual 2-wire partyline interface module for the HMS-4X main station.

The HelixNet IP networking guide provides specifications, best practices and guidance for the integration of HelixNet into an existing or new IP network.
