SVC420/820GPS-L
There are three ways of wiring. The first way is by connecting the 485 control wire to the
wire 485A and 485B on host. Connect the video cable to the host video input and then
provide power to PTZ. This kind of wiring will need to set the SVC420GPS/SVC820GPS-L
host data by corresponding to PTZ data and then use the remote controller or platform to
remotely control PTZ.
The second way is to connect the head of the 485 control wire directly to the
three-dimensional control keyboard. There is no need to connect the
SVC420GPS/SVC820GPS-L host as the video cable connects to the host video input.
Separate power supply to the PTZ and three-dimensional keyboard and then set the
keyboard parameters to correspond with the PTZ. This wiring way is the most practical one
because it uses three-dimensional keyboard to control PTZ, which is faster, easier and more
practical. It is recommended to use this way to install the PTZ.
The third way is to connect to both car host and three-dimensional control keyboard, so that
both can be controlled and platform remote can also be controlled.
