SERIAL COMMUNICATION CONTROL
In default working mode, the camera can be controlled via RS232 or RS485
(half-duplex mode). The parameters are as follows:
Baud rate: 2400/4800/9600 bit/s.
Start bit: 1 bit.
Data bit: 8 bits.
Stop bit: 1bit.
Parity bit: none.
When the camera initializes, Pan-Tilt rotates to the maximum position of top
right, then it returns to the center, and the process of initialization is finished.
(Note: If the position preset 0 has been stored, the position preset 0 is called up
after initialization.) Then the users can control the camera with commands in
the command list.
