3. Setup of the Baud Rate of Communication. As shown in Figure

2,3 SW2 is used to set the protocol of communication and the baud

rate used by the dome camera. DIP-6 and DIP-5 of SW2 are used to

select the baud rate of communication and 4 different baud rates can

be selected in maximum. If the controller adopts non-standard baud

rate, you can adjust it to be identical with that of the main machine as

per the following table.

Setup of Baud Rate

4. Selection of the Terminal Resistor of the Dome Camera..As

shown in Figure 2、3, JP1 is the select switch of the 120 Ω terminal

resistor on the bus RS485, on which only one terminal resistor of the

dome camera at the farthest end can be connected, while the terminal

resistors of other devices should be opened.
