4 Camera Control
The camera can be controlled through serial communication. Two methods
can be used to change the camera
’s parameters. The first approach is to
change parameters using CLISBeeCtrl (Camera control software). (See
“8
CLISBeeCtrl
”.) Or you can also change the parameters directly from your
application by using binary read/write commands to set values in the camera
register.
The camera can be used without the serial interface after it has been set up
correctly.
4.1 Flow of Camera Control
4.1.1 Command Overview
The serial interface uses a simple ASCII-based command.
Communication begins when the computer sends control commands to the camera.
The camera receives and interprets the computer commands and then executes
control operations accordingly.
Transmission ends when the camera returns the analyzed results of the control
commands to the computer.
Always allow the previous transmission to end before starting the next
transmission. (Only one command can be sent per transmission.)
