1. Maximum wiegand cable length is 150 meters and requires a high
quality shielded cable with minimum AWG18 dimension (=0.8231mm2) 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 & Clock/Data 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. RS 485/OSDP requires twisted pair cable.
