Power Failure During A Firmware Update-Now What; Cabling And Communication Issues - Dalsa Genie Nano Series User Manual

Power Failure During a Firmware Update–Now What?
Don't panic! There is far greater chance that the host computer OS is damaged during a power
failure than any permanent problems with the Nano. When electrical power returns and the host
computer system has started, follow this procedure.
Connect power to the Nano. The Nano processor knows that the firmware update failed.
•
• The Genie Nano will boot with the previous version of firmware and will operate normally.
• Perform the firmware update procedure (see File Access Control Category) again.

Cabling and Communication Issues

With only two cables connected to Nano, possible cabling issues are limited.
Power supply problems:
If the Nano 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 Nano 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 Nano 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 Nano is in a high vibration environment.
See Ruggedized RJ45 Ethernet Cables.
• Check the Ethernet status LEDs on the NIC used with the camera. 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•Programs•Teledyne DALSA•Sapera LT•Tools•Log
•
Viewer. Start the Nano 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.
