Remote Control Status Unit (RCSU)

The Selex ES® Model 2238 Remote Control Status Unit (RCSU) has the ability to monitor and control all ground navigation equipment, such as ILS, VOR, DME, TACAN, as well as other airport systems. The 2238 RCSU combines a fully functional Air Traffic Control tower cab-mounted display system with the most advanced remote maintenance capability, including remote adjustment of NAVAID parameters not previously available in the industry.

  • Available in a range of COTS and customized COTS configurations targeting 19” rackmount, desktop installation, or deployment via Virtual Machine container
  • TCP/IP LAN Connectivity, Single Point RMM Connectivity, security password protection, and map-based graphical user interface

As an alternative, the Selex Model 2240 RCSU is designed for installations consisting of up to three NAVAID stations. It incorporates LED status indicators. An external battery unit provides battery backup operation in the event of an AC power failure. The 2240 RCSU is designed for installation in a standard 1U equipment rack panel space in a control tower equipment room.

Remote Status Display Unit (RSDU)

RSDU-tablet-1The RSDU is the preferred interface for ATC situations requiring monitoring of multiple runways and approaches. RSDUs are typically installed at ATC locations, as well as at other points around the airfield requiring at-a-glance status of the associated navigation equipment. Any practical number of RSDUs can be connected to the 2238 RCSU over a TCP/IP network connection. Several form factors are available, including large touchscreen LCDs, compact panel mount systems, and notebook PC-based systems.
