Setting the RS-485 communication
RS-485 is the interface that connects the dome camera to the control device.
Consequently the RS-485 setup of the dome camera and the control device must be
identical.
Locate the communication DIP switch block (see B, Figure 3 on page 9). See Figure 4
below for an explanation of the communication DIP switches of the dome camera.

6. Not used
The RS-485 default setting is half-duplex (see Figure 4 above). This setting should only
be changed by a qualified CCTV specialist. DIP switches SW3 and SW4 are used for
termination and Line Lock adjustment respectively. The SW5 DIP switch is used to
restore the dome camera to the factory default status.

Setting the dome camera site ID
Before turning on the dome camera, you must set the dome camera site ID. Each
dome camera connected to the same network must have a unique ID. Use the 10-bit
DIP switch to set the dome camera’s site ID setting.
To set a dome camera site’s ID
1. Locate the dome camera site ID DIP switch block (E, Figure 3 on page 9).
2. Using Table 5 on page 13, determine which DIP switches when turned on will add
up to the site ID number for that dome camera. See Figure 6 on page 14
for an
example.
