◆
When connecting, make sure the polarity of RS485 controlling cable is correct: A: RS485 positive, B: RS485
negative.
◆
If wrongly connected, the IR Low-speed Dome Camera will be out of control.
5.4.3 Switch on Power
a Make sure the polarity of plugs, sockets and the connection of cables is correct, then switch on power
b The IR Low-speed Dome Camera begins to do the self-check: it moves pan 360°, tilt 90°, then moves to its original
position, then zooms in and zooms out once. Through the self-check, the unit checks the mechanical moving performance
of the pan/tilt, the electrical performance of the controlling system, the controlling of the camera module. After the IR
Low-speed Dome Camera finishes self-check, it stays at the original position and is ready to receive controlling
instructions.
c Use controlling device to control the IR Low-speed Dome Camera, checking whether it can perform the functions of the
pan/tilt and the lens of the camera module. If not, please check the configuration of communication protocol, Baud rate
and address, and the connection of 485 controlling cable.
VI. Configure the system of the IR Low-speed Dome Camera
Before the installation of the IR Low-speed Dome Camera, you must confirm if the protocol, the Baud rate of the
controlling system and the address code of the IR Low-speed dome camera is right (the factory default is: Pelco_D for
protocol, 4800bps for baudrate, 001 for address code). You must make sure that the configuration of them must be
identical to that of the controlling device. The corresponding switches for configuration is shown in the following figure:
6.1 Configure Protocol
The DIP-1 and DIP-2 of the 4-button switch on the PCB board is for communication protocol configuration. Please
