RS-232 Serial Communication
The RS-232 serial port (color-coded blue) near the center of the camera's back panel provides another
means of controlling the camera.

9600 baud is preferred. Use 38400 baud only if the connected device does not have a 9600 baud setting.
The camera's response time is the limiting factor for control speed. RS-232 control is less likely to flood the
camera with commands at 9600 baud.
