To reduce the chance of stress and vibration on the cables, we recommend that you use
cable clamps, placed close to the camera, when setting up your imaging system. Stress or
vibration of the heavy CLHS AOC cables may damage the camera’s connectors.
Establishing Camera Communications
When you power up the camera, observe the LED status indication on the back. The LED will
indicate one of the following status conditions:
LED State
Description
Off
Camera not pow er up or w aiting for the softw are to start
Constant Red
The camera BIST status is not good. See BIST status for diagnosis.
Blinking Red
The camera has stopped output and has shut dow n some components due to an over temperature
condition.
Blinking Orange
Pow ering Up. The microprocessor is loading code.
Blinking Green
Hardw are is good, but the CLHS connection has not been established or has been broken.
Constant Green
The CLHS Link has been established and data transfer may begin
When the camera’s LED state is steady green open CamExpert.
1.
CamExpert will search for installed Sapera devices.
2.
In the Devices list area on the left side of the window, the connected frame grabber will be
shown.
3.
Select the frame grabber device by clicking on the name.
In a change from previous versions of the Sapera GUI, only one instance of CamExpert is required
to send commands to the camera and view images.
Selecting the Data Format
The camera can output data in the following formats:
Mono8
Mono12
Please refer to the frame grabber user’s documentation for further details on selection input and
output pixel formats.
Establishing Data Integrity
1.
Use the camera’s internal triggering. This allows for initial imaging with a static object and
no encoder input is required.
2.
Enable the camera to output a test pattern.
