Remote Wireless Relay Control
NCD wireless relay controllers allow remote operation of electrical equipment from your computer up to 3,000 feet away.  NCD wireless relay devices wait for you to transmit commands from the AirControlLR or the TranSendES device communicators, which connect to the RS-232 serial port of your computer.  NCD Wireless relay controllers are ideal for remote switching of communication signal, lighting, audio, video, and much more.  An unlimited number of remote relay controllers can be controlled individually or simultaneously using our EWC wireless networking standard.
