2.1. It's necessary to address the readers to distinguish between doors and the status (entry or exit)
in the access controllers AccessPRO2 and AccessPRO4
2 2.2. The Dip Switch is located on the backside of the reader, it has 6 switches that are explained below:
1. The first four switches are used to establish the RS485 address in the reader through the binary code.
2. Switch 5 is not used.
3. Switch 6 is the end of line resistance. It's activated on the last reader of the RS485 serial connection
enabling a 120 Ohm resistance.
4. Activate switch 6 in case the cabling exceeds 100 meters.
5. Use UTP Cat5 cable for RS485 communication.
