n3 CPU

Top - CroppedClearbox Systems is proud to present n3, its next generation in innovative monitoring and control solutions. The n3 provides the next generation of miniaturised remote site management hardware that has been developed to meet mil-spec standards for dust, water, temperature, vibration and EM radiation. The unique camouflage case design has interlocking properties as well as improved heat dissipation. The n3 CPU is the brain of the remote site management solution. It features an 800MHz CPU, with 2 ethernet, 2 USB, 2 serial Temperature, 6 digital inputs and 2 digital outputs. It is designed to run Compass or TacNMS and provide local and remote equipment management for your remote site.

In a deployed network of satellite terminals, the n3-CPU provides remote visibility and control of the deployed terminals. Central operators can check and modify configuration, re-engineer links and reduce interference through inadvertent emissions. When operating with a centralised Compass or Foresight NMS the n3-CPU provides an integrated view of the deployed network for M&C and management purposes. This reduces the burden on remote terminal operators. When used in deployed satellite terminals the n3-CPU is designed to enhance and complement the terminal M&C capability and provide a terminal agnostic view of the network to the remote and central operators.

The n3-CPU can be deployed with the n3-DIG, Digitiser for spectrum analysis, and n3-SIG, Signal generation module.
