Cypress Suprex® RF Series - Accessory I/O - AUX I/O
The SPX-5631 / SPX-5641 has an auxiliary I/O signal going from the reader side to the panel side. The SPX-5631 /
SPX-5641 is able to transmit this signal to the panel with the AUX Input and AUX Output pins. The AUX In pin is a digital
input and the AUX Out pin is a digital output. The AUX In pin has two states, 5V (high or normal) and 0Volts (low or active).
The AUX Out pin will mirror the state of the AUX In pin.
The AUX I/O Signal Diagram below shows how this signal is passed through the SPX-5631 / SPX-5641.
