User's Manual
Setting Termination Resistance
In order to prevent signal reduction, the termination resistance of the 2 end
units, which are the distant paths for camera and controller to be connected
on the RS485 interface, should be connected.
As the termination resistance is built in the camera, whether to make the
termination resistance valid or invalid is selected with the DIP switch.
See the connection diagram below for determining to which device the
termination resistance will be connected to.
Set up the termination resistance in the dark products.
The installation distance of the product for the termination resistance setting
should be less than 1.2 Km. (Maximum cable length is 1.2 Km according to
the RS-485 standards.)
