IPRC cmd is a command-line utility for Windows and Linux that controls the outputs of all I/O Controller and IP Relay product variants. By invoking the program from the command line (or a .bat file), a defined (relay) output can be set or reset.
IPRC cmd is intended for applications and scripts that need a simple way of controlling digital outputs. You can modify the utility to suit your needs – it is included in the HWg SDK.
