Linea Lite GigE Series Camera Troubleshooting • 169
Cabling and Communication Issues
With only two cables connected to Linea Lite GigE possible cabling issues are limited.
Power supply problems:
• If the Linea Lite GigE status LED is off, the DC supply power is not connected or faulty. Verify
the power supply voltage.
Communication Problems:
• Use a shielded cable where the connector shell electrically connects the Linea Lite GigE chassis
to the power supply earth ground. This can eliminate trigger issues in a high EMI environment.
• Check that the Ethernet cable is clipped both to the camera and the NIC or switch on the other
end.
• Verify the Ethernet cabling. Poor cables will cause connections to auto-configure at lower
speeds.
• Use a secured Ethernet cable when the Linea Lite GigE is in a high vibration environment. Refer
to Ruggedized RJ45 Ethernet Cables
section.
• Check the Ethernet status LEDs on the Linea Lite GigE RJ45 connector. The Link Status
indicator should be on and the activity LED should flash with network messages.
• Verify the Ethernet cable is CAT5e or CAT6. This is very important with long cables.
• When using long cables up to the maximum specified length of 100 m for gigabit Ethernet,
different NIC hardware and EMI conditions can affect the quality of transmission.
• Minimum recommended Ethernet cable length is 3 feet (1 meter).
• Use the Log Viewer tool (see point below) to check on packet resend conditions.
• Run the Sapera Log Viewer: Start•Programs•Teledyne DALSA•Sapera LT•Tools•Log
Viewer. Start the camera acquisition program, such as CamExpert. There should not be any
"packet resend" messages, else this indicates a control or video transmission problem due to
poor connections or extremely high EMI environments.
