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

instructions and replies. Relays permit switching of modest currents. IR ports can send infrared signals which emulate typical remote control devices that control (for instance) televisions and video recorders. Input/output ports detect contact closures.
AMX supplies an IDE known as NetLinx Studio which allows a proprietary language to be edited, compiled and sent to the NetLinx controller. NetLinx also contains an interface which allows it to utilize Java based modules.
Earlier models of AMX controller were named Axcent.
