Baudrate Settings
The number 7 and 8 DIP switches are used for setting the baudrate of the speed dome. The
baudrate can be 2400bps, 4800bps and 9600bps. The baudrate will be set as 2400bps by default if it
is out of this range. Refer to the following table:

Power Cable Requirement
When the speed dome uses standard AC power supply, the power cable should meet the demand.
The formula of the cross-section S (mm²) and the maximum transmission distance L (m) of the bare
wire is L=50*S.
