4.4 Control Protocol and Baud Rate
Control protocol and baud rate must be set correctly in the dome camera in order to
establish proper control communication between the camera and control device.
Be sure that the same protocol and baud rate must be implemented in control
device, too.
3 types of protocol and 3 levels of baud rate are provided by this speed dome,
through an 8-bit DIP switch labeled DS1.
