Serial Interface: How to Control the Camera

Serial Interface: How to Control

the Camera

All camera features can be controlled through the serial interface, which is part of the Camera Link

interface standard. The camera can also be used without the serial interface after it has been set up

correctly. The serial interface uses a simple ASCII-based protocol and the camera does not require any

custom software.

Functions available include:

•

Controlling basic camera functions such as gain and sync signal source

•

Data readout control

•

Generating a test pattern for debugging

Note:

If you have installed the DALSA Sapera LT vision software package, you can use the CamExpert

application to communicate with the camera. CamExpert provides a user-friendly graphical interface that

allows you to directly adjust the camera parameters with typical window elements, such as drop-down lists,

without using explicit serial commands.

Serial Protocol Defaults
