HLI-2W2 Interface Module
HLI-2W2
The HLI-2W2 Interface Module enables two channels
of Clear-Com or RTS intercom to interface with
HelixNet intercom channels.
Key Features And Benefits
• 2-wire interface module
Description
The HLI-2W2 is a 2-wire interface module that fits within one of the three rear
panel interface slots of a HelixNet Main Station (HMS-4X). The HLI-2W2 connects
two 1-channel 2-wire analog audio circuits to HelixNet intercom channels. Two
3-pin XLR-F connectors on the module connect intercom lines, such as Clear-Com
or RTS, and can be assigned via the main station menu.
• Two 3-pin XLR-F connectors per module
