Notes:
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.
2. Wiegand requires dedicated wires for external control of green LED,
red LED, buzzer and keypad backlight LED.
3. When utilizing the GPI/O’s, each respective GPO1 or GPO2 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.
