Comrex Connect Modems

The Comrex Connect Modem is designed to support the unique needs of remote broadcasters. A high-powered, industrial strength 4G/LTE modem outfitted with a high-gain antenna, the Connect Modem is more powerful than most USB data modems available on the market, to handle the heavy data load of a broadcast over IP.

Please note: FW 4.5p6 or higher is required on ACCESS MultiRack to use the US Connect Modem.

Fleet Commander

Fleet Commander is a software application for controlling multiple Comrex IP audio codecs simultaneously. Rather than logging into each codec individually and juggling a desktop full of tabs, Fleet Commander puts you in control of your codec fleet through one unified interface. With the ability to manage all codecs from one simple window, this easy-to-use tool can save time and increase productivity for busy engineers.

Fleet Commander contains all of the functionality of the Web-based Interface, but also comes with a few more features like active metering and the ability to copy peers and profiles between codecs. A Windows application, Fleet Commander can be used to manage every Comrex IP Audio codec in your fleet (depending on CPU and network limitations).


  • Simple to use
  • Unified interface for multiple codec management
  • Compatible with Windows 7, 8, and 10
