CNR-Monitor joins the family in CNR 4.2

Calytrix Technologies has released a new version 4.2 of its Comm Net Radio (CNR) for training of military, homeland security, first responder and other radio users. CNR encapsulates all of the products in the CNR family of simulation and training related communication products.

Calytrix's CNR-Sim is software for either Windows or Linux that simulates a multichannel radio. Training with CNR-Sim provides PC users the comm functionality of a real radio. However, voice communications through the simulated radio are processed over a computer network and not broadcast over the air, thus limiting the radio traffic to the confines of the training environment. CNR-Sim is compliant with IEEE standards for simulated radio communications (specifically, DIS and HLA network protocols). Calytrix's CNR family of products also includes CNR-Log to record and replay simulated radio traffic, CNR-Monitor for remote management of a CNR network and CNR-Touch for touchscreen control of multiple independent simulated radios.

CNR-Sim in Base and Pro versions supports an unlimited number of simulated channels (frequencies), Voice Operated Keying (VOX) capability, and user control of signal clarity and noise. In addition, Calytrix offers a free version of CNR-Sim that supports just two simulated radio channels.

CNR 4.2 improves on the previous 4.1 release:

  • CNR-Sim has been improved with a collection of bugfixes.
  • CNR-Touch
    • This now includes a fullscreen toggle button on the interface.
    • CNR-Touch is now supported with a customised driver for use on the Mimo 720S. Which means other applications can be run, and the user can interact with the CNR on the device without affecting the program on the primary display.
    • Other devices using the Touch-Base family can also be used, however Calytrix has primarily targeted testing on this device.
  • CNR-Monitor is now provided free of charge.
    • CNR-Monitor allows you to view the status of all DIS radios on the network.
    • CNR-Monitor provides the ability to control remote instances of CNR-Sim (Pro license required for each CNR-Sim instance that you wish to control).
  • White Noise Demo
    • This is a demonstration of applying white noise to CNR-Sim instances (with Pro license) using the provided API.
    • This is provided in executable and source formats which can then be extended by the user.
  • VBS-Plugin.
    • This is a demonstration of the capability to communicate with CNR-Sim on a specified port to gather information about the currently running radio.
    • This plugin does not require a Pro license, and will operate with both Standard and Free versions.
