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 R430PL_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.
