Auto-Tracking Camera
79068-Auto10 User Manual
4.3 Serial Communication Control
Under common working conditions, the camera can be controlled through the RS-232/RS-485
interface (VISCA). RS-232C serial parameters are as follows:
Baud rate:
2400/4800/9600/115200 bits / sec
Start bit:
1
Data bits:
8
Stop bit:
1
Parity:
None
After powering on, the camera will first go left, then back to the middle position. Self-test is finished
after the zoom has moved to the farthest, and then back to the nearest, position. If Preset 0 has been
saved before, it will move to that position after initialization. At this point, the user can control the
camera using the serial commands.
