Notes:
1. Maximum Wiegand cable length is 150 meters and requires a high quality shielded
cable with minimum AWG18 dimension (=0.8231 mm
2
) in an environment free from
electrical noise. A cable with smaller dimension or an installation environment with
electrical disturbances will reduce the maximum cable length.
2. Wiegand requires dedicated wires for external control of Green LED, Red LED, Buzzer
and Keypad backlight.
3. When utilizing the GPI/O’s, each respective GPI/O1 or GPI/O2 must be connected
to each respective pin and also to GND. The general purpose input/output will only be
activated if so applied in the reader configuration.
4. RS485/OSDP requires twisted pair cable.
