Troubleshooting
Linea Lite GigE Series Camera
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. See
Ruggedized RJ45 Ethernet Cables.
•
Check the Ethernet status LEDs on the Linea Lite GigE RJ45 connector. The Link Status
indicator is on and the activity LED should flash with network messages.
•
Verify that the Ethernet cable is CAT5e or CAT6. This is very important with long cable lengths.
•
When using very long cables, up to the maximum specified length of 100m 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 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.
