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.
