Genie Nano-CL Series™ Troubleshooting • 111Power Failure during a Firmware Update–Now What?Don’t panic! There is far greater chance that the host computer OS is damaged during a powerfailure than any permanent problems with the Nano. When electrical power returns and the hostcomputer 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.• The Nano Self Status (deviceBISTStatus) will return that the last firmware update failed.• Perform the firmware update procedure (see File Access Control Category) again.Cabling and Communication IssuesWith only camera link cables and possibly an external power supply connected to Nano-CL, possiblecabling issues are limited.Power supply problems:• If the Nano status LED is off, the DC supply power is not connected or faulty. Verify the powersupply 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 thepower 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•LogViewer. Start the Nano-CL acquisition program, such as CamExpert. Review the log output forerror messages.Recommended HardwareThe Nano-CL has a Camera Link Pixel Clock of 85MHz. Teledyne DALSA Xtium series framegrabbers 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 cablequality, cable length and Frame Grabber used.• Teledyne DALSA has qualified the Xtium frame grabber with 10 meter cables at 85MHz (10-tapconfiguration). Camera Link cables (end to end standard solutions of various lengths) arerecommended from Components Express and Alysium, who also offer I/O signal solutions asdescribed in this manual. See Cable Manufactures Contact Information for contact information.• The Teledyne DALSA Xcelera frame grabber (10-tap configuration) has been qualified using upto 4 meter cables with the Nano-CL.• Use of third party frame grabbers and other cables requires thorough testing by the user.
