David Clark C91-20RD Radio Interface Cable for 9100 Intercom System - 6-Pin - 20ft - 40892G-19

The David Clark C91-20RD Radio Cable (40892G-19) is a Series 9100 Digital Intercom System radio interface cable designed to connect a marine or mobile radio to the U9100 Master Station based intercom network. In aviation ground support, this cable is used when teams want to integrate a radio channel into the digital intercom system for ramp operations, airport ops coordination, maintenance support, or deicing communications. Because radio interfaces vary by manufacturer and model, the radio end of the cable is intentionally left unprepared so installers can terminate it to the correct radio connector, making it a flexible solution for radio integration planning across different fleets and sites. It can also be used as a remote push-to-talk cable with a U9111 headset station in certain installations.

• Interfaces a marine or mobile radio to the Series 9100 Digital Intercom System through the U9100 Master Station.
• 20 foot radio interface cable format supports practical installation routes in vehicles, hangars, and equipment enclosures.
• Radio end is left unprepared so installers can apply the correct radio-specific interface.
• Can also serve as a remote push-to-talk cable with a U9111 headset station in applicable configurations.

Key Features

• Designed for radio integration workflows where different radio models require different terminations.
• Supports mission-critical communications planning for aviation ground support and other high-tempo environments.
• Pairs well with Series 9100 modular expansion where radio access and routing are configured through the system architecture.

When you need to integrate a mobile or marine radio into a Series 9100 digital intercom network for aviation ground operations or industrial teams, the David Clark 40892G-19 provides a flexible, installer-ready cable solution designed for rugged, real-world installations.
