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 NCCtrl (Camera control software). (See “8 NCCtrl”.) 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

operation accordingly.

Transmission ends when the camera returns the analyzed results of 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.)

4.1.2 Command Format (PC to Camera Transmission)

Format 1 CMD CR

Format 2 CMD

VAL CR

CMD: Control text (1 Byte) Use 1 lowercase letters only. No numerals allowed.

CR:

Carriage Return (0x0D)

VAL: Setting value (decimal, 1 Byte x maximum 7 digits)

l CR

g70 CR

4.1.3 Reply Format (Camera to PC Transmission)
