Wiegand Data 0 / Magstripe Clock
Wiegand Data 1 / Magstripe Data
RS422 / RS485
The RS422 or RS485 communication can be used for communication with the Access Control System, configuration
settings and firmware update. Only the RS422 or the RS485 interface can be active (not both), this is determined by
SW1-2 (located near the USB port).
The maximum cable length for both interfaces is 65 meters / 213 feet. This distance can be increased by adding
termination resistors, using twisted cables and/or configuring a lower baud rate.
Wiegand / Magstripe
The Wiegand and Magstripe communication can be used for communication with to Access Control System only. The
Wiegand and Magstripe can operate with a maximum cable length of 150 meters / 500 feet.
