4.8 Serial Communication Control
RS232 Communication Control
The camera is controlled via RS232. The
RS232 serial port parameters are as follows:
Baud rate: 2400/4800/9600/38400 bit/s;
Starting Position: 1 bit
Data bit: 8 bits
Stop bit: 1 bit
Check digit: None
RS485 Communication Control
Control camera via RS485, half duplex mode:
Baud rate: 2400/4800/9600/38400 bit/s;
Starting position: 1 bit
Data bit: 8 bits
Stop bit: 1 bit
Check digit: None
After power on, the camera goes to the upper
right limit and then back to the middle position.
The zoom lens is pulled to the farthest position,
auto focus, and the aperture is adjusted to the
default value. If the camera has preset 0 saved,
the camera will be set to position 0 after the
initialization is completed. At this point, the
user can use the serial port command to
control the camera.
List of protocols (omitted)
The serial port of the camera follows the
VISCA/Pelco-D/Pelco-P standard protocol. If
secondary development is required, the
camera can be controlled according to the
standard protocol.
For a detailed list of VISCA/Pelco-D/Pelco-P
protocols, contact the manufacturer.
