Laxton Advanced relay I/O controller is an input/output board used for connecting external sensors and switches to computers. This controller accepts user inputs from switches, relays, coin collectors and sends a corresponding keyboards command to the PC. It has 3 general purpose relay outputs controlled from the CAPS/NUM/SCROLL lock keys from the PC.
