PELCO_D1
If the controlling device could only support the preset position numbers below 128, please use PELCO_D1 controlling
protocol.
6.2 Configure Baud Rate
DIP-3 and DIP-4 of the 4-button switch on the PCB board is used to configure Baudrate of communication, the
default configuration is 4800BPS. Following table shows states of coding switches and cosrresponding Baudrate.

Remark:
If the IR Low-speed Dome Camera is used at the farthest terminal, there should be a parallel connection of a
120Ω terminal matching resistor between A, B lines of RS485.
6.3 Configure Address
Before actual operating of the unit, the address of the IR Low-speed dome camera should be configured. The buttons
from DIP-1 to DIP-8 of the 10-button Switch are used to set address of the IR Low-speed Dome Camera from 1 to 255.
The coding switches from DIP-1 to DIP-8 are equivalent to a 8-bit binary figure. The state “ON” of each bit means “1”
while ”OFF” means ”0”. Corresponding state of coding switches and address is shown in the table below:.
