USB Relay

The USB interface module makes it easy to control relays using the USB port.  Simply plug into any available USB port and start controlling the relays and reading the AD Inputs using standard serial commands.  NCD USB Interface modules feature genuine FTDI USB to Serial Converter Chips, the very best in the industry!  With drivers available for Windows, Mac, Linux and much more, users may communicate to NCD devices using a virtual COM port, which greatly simplifies software integration.

The ProXR Command Set

The R420PL_USB operates by sending commands to the board to control the relays which allows you to program in almost any language.  The ProXR Command Set is the industry leading command set for controlling the relay and reading the inputs on the board.  Commands can be as simple as turning on/off the relay and as complex as adding delays and other features to the command such as flashers, duration timers, and reading the status of the relay.
