MODEL 2238
Remote Control and Status Unit

　　The Model 2238 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 Model 2238 RCSU com-bines a fully functional Air Traffic Control tower cab-mounted display system with the most advanced remote maintenance capability, including remote adjustment of ILS parameters not previously available in the industry. Combined with the Remote Status Monitoring System (RSMS) software, the user has the ability to manage an entire network of systems countrywide. Optional Digital Signal Processing (DSP) interface cards allow control and monitoring of legacy tone-based navaids and equip-ment provided by other manufacturers. The Model 2238 RCSU was designed to reduce operational costs by improving Air traf-fic Controller and maintenance technician efficiency.
The Model 2238 RCSU provides a touch screen display with a color, graphical layout of the airport, which can be either a sim-ple bitmap or one enriched with pertinent runways and taxiways. Superimposed on the display are color coded icons represent-ing navigation aids in their respective locations on the airport. An audible alarm is triggered in the event of an alarm or alert condition at any of the navigational aids. This advanced display reduces the controller workload by providing at-a-glance real time status of the associated equipment. Air Traffic Controllers can also control individual navaids by touch-ing the appropriate equipment icon on the touch panel screen to display a more detailed status and control panel for that equip-ment. The controller can easily and securely change the selected approach end of any of the runways.
The Model 2238 RCSU can either be desktop-mounted or installed in a standard 19” rack, occupying 5U of rack space.
REMOTE STATUS DISPLAY UNIT (RSDU)
　　The optional Model 2238 Remote Status Display Unit provides the same graphical map-based user interface to the associated navigation equipment as on the Model 2238 RCSU. The RSDU is the preferred interface for ATC situations requiring monitoring of multi-ple 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 prac-tical number of RSDUs can be connected to the Model 2238 RCSU over a TCP/IP network connection. Several form factors are available, including large touchscreen LCDs and more compact notebook PC-based systems, each configuration including bat-tery-backed operation.
REMOTE STATUS UNIT (RSU)
　　The Model 2138 Remote Status Unit displays the summary level status of the equipment being monitored on a small panel suitable for installation in a console in the Control Tower. The RSU is a cost-effective status display panel that can support one or two opposing approaches on a single runway. It is linked to the RCSU through an RS-422 serial communication link, and can optionally be supplied with a battery backup unit.
