The SCU-300 series of System Control Units was a state-of-the-art antenna and receiver controller and is still in use today across the country, but it has been replaced by the more advanced SCU-400 series of controllers.
The SCU-420 Series is the replacement for the SCU-320 Series, incorporating the same field proven latching relays, digital inputs and outputs, analog inputs and outputs, serial COM ports and advanced regenerative control for the positioner of steerable antennas. In addition, the SCU-420 Series features improvements such as:
- A built in Ethernet port for remote control over IP
- An additional serial COM port
- Three USB ports
- System control unit software and configuration changes are now possible via USB memory stick.
- New CPU running embedded Linux
- Extended temperature range for rugged environments
