USB ProXR Enhanced with UXP:

USB Virtual COM Relay Controller with
UXP Expansion Port and XR Expansion Port

About USB:

Our New USB ProXR Series Relay Controllers make it easier than ever to add computer controlled switching to your most demanding computer control applications.  Simply connect to your computer and this controller mounts as a Virtual COM Port on your PC, allowing easy programming from any language that supports serial communications.

This ProXR series controller connects to the USB port of your computer 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.
