28 NEDXCM2085DLCT3 UME-0063-024 Camera ControlThe camera can be controlled through serial communication. Two methods can beused to change the camera’s parameters. The first approach is to change parametersusing CLISBeeCtrl (Camera control software). (See “8 CLISBeeCtrl”.) Or you can alsochange the parameters directly from your application by using serial communicationcommands to set values in the camera register.Once the camera has been set up according to your requirements, the camera canbe used to read data without need of controlling it via the serial interface.4.1 Flow of Camera Control4.1.1 Command OverviewThe serial interface uses a simple ASCII-based command. Communication begins when the computer sends control commands to thecamera. The camera receives and interprets the computer commands and then executescontrol operations accordingly. Transmission ends when the camera returns the analyzed results of the controlcommands to the computer. Always allow the previous transmission to end before starting the nexttransmission. (Only one command can be sent per transmission.)4.1.2 Camera Receiving Message (PC Sending Command) Format 1 CMD CR Format 2 CMD□VAL 1 CR Format 3 CMD□VAL 1□VAL2 CR Format 4 CMD□VAL 1□VAL2□VAL3 CRCMD: Control text (3 Bytes) Use 3 lowercase letters only.
