Notice: Please make sure the power is off before setting, and restart the speed dome to enable a new value after changing.

2.3.5. RS-485 Bus Terminator Resistance

For central controlling, the terminator resistance should be set for the device that is the furthest one away from the controller. The 8th bit on the SW2 is a switch to enable or disable the terminator resistance. When it is switched ON, the BUS terminator resistance is connected.
