Chapter 5 Appendix
The camera could be controlled through RS232/RS485 interface; RS232C serial parameter are as follows:
Baud rate: 2400/4800/9600/115200 bits / sec; Start bit: 1; data bits: 8; Stop bit: 1; Parity: None.
After power on, the camera first goes left, then back to the middle position. Self-test is finished after the zoom
moved to the farthest and then back to the nearest position. If the camera saved 0 preset before, it will be back
to that position after initialization. At this point, the user can control the camera by the serial commands.
