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 restarted follow this procedure.
•
Connect power to the Nano-CL. The Nano processor knows that the firmware update failed.
•
The Nano-CL will boot with the previous version of firmware and will operate normally.
•
(deviceBISTStatus) will return that the last firmware update failed.
•
Perform the firmware update procedure (see File Access Control Category) again.
Cabling and Communication Issues
With only camera link cables and possibly an external power supply connected to Nano-CL, 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.
•
If using PoCL power, verify that the frame grabber used has activated its PoCL source.
Communication Problems:
•
Use shielded cables 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.
Purchase camera link cables from quality certified sources.
•
Use the Log Viewer tool (see point below) for error conditions.
•
Run the Sapera Log Viewer: Start•Programs•Teledyne DALSA•Sapera LT•Tools•Log
Viewer. Start the Nano-CL acquisition program, such as CamExpert. Review the log output for
error messages.
Recommended Hardware
The Nano-CL has a Camera Link Pixel Clock of 85MHz. Teledyne DALSA Xtium series frame
grabbers are recommended for error free acquisitions (contact sales for additional information).
Cable Length Considerations
•
The camera outputs data at 85MHz on the Camera Link cable.
•
The high data rate on the Camera Link cable can cause compatibility issues based on cable
quality, cable length and Frame Grabber used.
•
Teledyne DALSA has qualified the Xtium frame grabber with 10 meter cables at 85MHz (10-tap
configuration). Camera Link cables (end to end standard solutions of various lengths) are
recommended from Components Express and Alysium, who also offer I/O signal solutions as
Cable Manufactures Contact Information
•
The Teledyne DALSA Xcelera frame grabber (10-tap configuration) has been qualified using up
to 4 meter cables with the Nano-CL.
•
Use of third party frame grabbers and other cables requires thorough testing by the user.
