Troubleshooting

6.1 Check Simple Things First

When troubleshooting, you want to start the process with the obvious components contained within your system:

•Computer system: hardware & software

•Is the frame grabber plugged into the correct slot on the mother board?

•Are all electrical connections secure?

•Check to make sure that your light source is fully functional

•Make sure that the pin configurations for all of your cables are correct

•Make sure you have selected the correct lense for your camera

6.2 Use the Camera Control Interface to Perform Checks

In the Camera Control GUI, to verify that the camera returns preset data. Typical Gain Values are ≈ 400 while typical offset values are ≈64. Values such as 2047 indicate the camera is not communicating properly and the I/O cable connections (or wiring) is suspect.

6.3 Other Areas You Should Check

Contact Customer Support

Before you call for support, be sure to make a note of the camera settings and the frame grabber settings you are using. You should also have saved captured live images. Customer Support will frequently request that you e-mail copies of these captured images. See Section 7.

Connections

Double check the pin outs of your cable. Make sure that the connections to the back of the camera and to your PC are secure.

Power Supply Voltage

Make sure and measure that you have 12.0 volts at the camera connector.

Noisy Power Supply

Check your power supply voltage output(s). Check also the noise and ripple specification of your power supply and measure both at the power supply output.
