Troubleshooting

Linea GigE Series Camera

•

There is no image but the frame rate is as expected.

See "Camera is functional, line rate is as expected, but image is black" on page 128.

Other problems

•

Buffer Incomplete message. See Buffer Incomplete Error Message.

Verifying Network Parameters

Teledyne DALSA provides the Network Configuration tool to verify and configure network devices

and the Linea GigE network parameters. See section Network Configuration Tool of the Teledyne

DALSA Network Imaging manual, if there were any problems with the automatic Linea GigE

software installation.

Before Contacting Technical Support

Carefully review the issues described in this Troubleshooting section. To aid Teledyne DALSA

personnel when support is required, the following should be included with the request for support.

•

From the Start menu, go to Programs • Dalsa • Sapera LT • Tools and run the Log Viewer

program. From its File menu click on Save Messages to generate a log text file.

•

Report the version of GigE Vision software and Sapera version used.

Installation Issues and Functional Problems

This section covers issues that are apparent after installation or are indicated by the GigE server

tray icon showing a warning symbol.

Device Available with Operational Issues

This section considers issues with cabling, Ethernet switches, multiple cameras, and camera

exposure. All information concerning the Teledyne DALSA Network Configuration Tool and other

networking considerations, is available in the Teledyne DALSA Network Imaging manual.

Firmware Updates

As a general rule any Linea GigE installation must include the firmware update procedure (see "File

Access Control Category" on page 92). Linea GigE camera firmware that does not match a newer

version of installed GigE Vision software is likely to have unpredictable behavior. Problems might

be:

•

Linea GigE is not found by the device discovery process.

•

Linea GigE is found by the Sapera GigE Server but an application such as CamExpert does not

see the camera.

•

A Linea GigE that had a fault with a firmware update will automatically recover by booting with

the previous firmware version.

Important: New cameras installed in previously deployed systems are fully backward compatible

with the older vision application.
