Cabling and Communication Issues
With only two cables connected, the Linea SWIR GigE camera cabling issues are limited.
Power supply problems:
If the camera's 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 camera chassis to a
•
power supply's earth ground. This will eliminate trigger issues in a high EMI environment.
Check the Ethernet cable is clipped 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 camera is in a high vibration environment. See
•
Ruggedized RJ45 Ethernet
Check the Ethernet status LEDs on the camera's 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 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 • Programs • Teledyne DALSA • Sapera LT • Tools •
•
Log Viewer. Start the camera acquisition program such as CamExpert. There should not be
"packet resend" messages. This indicates a control or video transmission problem due to poor
connections or extremely high EMI environments.
