USB Virtual COM Relay Controller with 8-Channels of
Analog to Digital Conversion and the ProXR Command Set
Our New Serial ProXR Lite Series Relay Controllers make computer controlled switching more reliable than ever to meet your most demanding computer control applications. Simply connect to your computer and this controller mounts as a COM Port on your PC, allowing easy programming from any language that supports serial communications.
This ProXR Lite series controller connects to the Serial port of your computer (or a USB Port if used with a Serial to USB Adapter) and requires a 12VDC Power Supply. Once powered up, the relay controller waits for a command. A command consists of a few bytes of data. Usually between 2 and 6 bytes. Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command.
