Chapter 2 Installation and Wiring

2.1 Wiring

Users must connect wires according to the circuit diagrams on the following pages. Do not plug a modem or telephone line to the RS-485 communication port or permanent damage may result. The pins 1 & 2 are the power supply for the optional copy keypad KPV-CE01 only and should not be used for RS-485 communication.
