If the attached motorized camera is not on the support driver list, choose the proper UART interface and
pull down the driver list to select Custom Camera type and click on 
for further configuration.
Setup the serial "Port Settings" according to the instruction manual of the custom camera. The "Baud Rate (bps)" of the serial port is up to 115200 bps. Then enter the specific command related to PTZ in the respective field. The custom command for "Control Setting" should be edited in ASCII format. VisualServer will interpret the ASCII format command to binary string. For instance, “012000ABCD” will be sent out of the COM port as five hexadecimal bytes of 01, 20, 00, AB and CD. If the command string is composed of two or more commands, a comma ‘,’ should be inserted to separate each command. Each comma represents 200 milliseconds. For instance, a command to pan left may be “01000305” and a command to stop panning may be “01000300”. The user may edit the applicable command as “01000305,01000300” in the Move Left field. This means the camera will pan left for 200 milliseconds.
