NetLinx is both a range of controllers manufactured by AMX and the name of the proprietary programming language (loosely based on C) used to program the devices. The NetLinx controllers are rack mountable devices which run a version of VxWorks and integrate both a processor and device controllers and are typically utilized for audio-visual control systems. An example is the mid-range NetLinx Integrated NI-2100 controller which has 3 RS-232/RS-485 serial ports, 4 relays, 4 infrared/serial ports and 4 input/outputs. Read more on Wikipedia...
