The SPX-1400 from Cypress enables installers to connect door I/O over the same OSDP 2-wire data connection when installing an OSDP reader, enabling fewer conductors needed to connect the controller and physical I/O hardware (typically door strike, door position sensor, and REX switch).
The access controller and OSDP reader communicate transparently over the OSDP data connection between the SPX-1400 central and remote units. Physical I/O is handled only between the SPX-1400 units. Includes central unit (aluminum enclosure) and remote unit (outdoor-rated enclosure).
