CNR-Sim Calytrix CNR-Sim

 

Calytrix Comm Net Radio Simulator (CNR-Sim) is an affordable, easy to use, software only, multi-channel radio simulator for Windows and Linux.

CNR-Sim simulates communications via a multi-channel, Push To Talk (PTT) radio or Voice Operated (VOX) radio. CNR-Sim digitizes its user's voice into data packets that are sent across a standard computer network to other CNR-Sims (and compatible DIS radios) where the data packets are converted back to audio. Data packets comply to the Distributed Interactive Simulation (DIS) networking protocol standard; the optional CNR-Bridge permits use in HLA environments.

 

The Different CNR-Sim Licenses

 

CNR-Sim operates in 1 of 3 runtime modes:

  • CNR-Sim Free: zero-cost radio simulation, but limited to two fixed channels. (no license required)
  • CNR-Sim Base: unlimited, user-configurable radio channels and teams, and other features. ("Base" license required)
  • CNR-Sim Pro: adds signal degradations (simulated signal loss, noise, and jamming), application programmer's interface, & support for advanced CNR modules. ("Pro" license required)

CNR-Sim's basic features include:

  • Multi-Platform, and Software Only: No need to buy expensive hardware. Use any Windows or Linux computer with any compatible headset with microphone.
  • Unlimited Number of Channels: Define and use as many simulated radio channels (frequencies) as you like. {Note: CNR-Sim Free has only 2 fixed channels.}
  • Unlimited Number of Teams: Define and use as many Teams as you like. Each Team can be assigned a unique Team Color for ease of use.
  • User Configurable Hot Keys: Users may assign any keyboard entry sequence to any radio Channel. Pressing that key (or key sequence) at runtime mimics a radio's Push To Talk (PTT) feature, even when CNR-Sim is minimized and not in focus.
  • Usable with Hardware Push To Talk (PTT) Devices: Users can interface Push To Talk hardware products, such as an XKeys foot pedal.
  • Text Chat: permits instant text messages between CNR-Sim users tuned to the same simulated radio Channel
  • External Sound Transmission: transmits an audio file across the simulated radio network, upon user command (manually through the GUI) or by programmer’s instruction (through the API).
  • Shared Configurations: Configure Teams and Channels once, then share that configuration with other CNR-Sim users.
  • Configurable Audio & Networking: User controls for speech sampling rates & playback fidelity, Multicast/Broadcast, Full-Duplex and Half-Duplex communications, and audio data compression for efficient use of network bandwidth.
  • DIS Compliant: Configurable settings for DIS Radio PDUs. CNR-Sim can communicate with other DIS radios. CNR-Sim does not block third-party DIS applications from running on the same computer.

 

CNR-Sim API

A Software Development Kit (SDK) for C++ and Java is available for CNR-Sim, enabling programmers to develop applications to interact with and control CNR-Sim Pro radios. Only the Pro configuration of CNR-Sim responds to API commands. Through CNR-Sim's API, external applications can:

  • Discover CNR-Sim radios on the network
  • Connect to a remote radio
  • Power On and Off remote radios
  • Change Channels on remote radios
  • Adjust radio volume, signal degradation, and other parameters

 

CNR-Sim can be operated in various ways:

  • built-in GUI (all versions)
  • multi-radio GUI (Pro mode)
  • programmer's instructions (API control in Pro mode)
  • realistic radio faceplates (optional CNR-Skins add-on module)

CNR-Sim is generally used with CNR-Log recording simulated radio communications for later replay, such as during After Action Reviews (AARs). VBS2's AAR function uses CNR-Log in this way.

 

CNR-HUD

A plug-in for VBS2 that displays CNR-Sim's basic radio channel info onto VBS2's main screen. CNR-HUD is distributed with the standalone version of CNR and as part of VBS2 from version 1.50.

CNR-Sim's usefulness is further extended with specialty electronic products, including CNR-Live, CNR-Sidetone and CNR-Intercom.
