114 • Troubleshooting Genie Color Series-GigE Vision Camera
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 Genie. When electrical power returns and the host computer system has started, the
Genie firmware reprogramming sequence is as follows.
• Connect power to the Genie. The Genie processor knows that the operating firmware is corrupt.
• The Genie status LED is slow flashing red. This will continue for about 2 minutes (pre-2007 Genie cameras
may take up to 5 minutes and has no led status).
• During this period, the Genie is loading embedded write-protected firmware. When the status LED goes blue
the Genie is initialized with a minimal safe boot firmware.
• The Genie is now operating normally as a network device but will not function as a camera.
• Perform the firmware update procedure (see "
Updating Genie Firmware" on page 27) again. The Genie is now
be ready for use.
Cabling and Communication Issues
With only two cables connected to Genie, possible cabling issues are limited.
Power supply problems:
• If the Genie status LED is off, the DC supply power is not connected or faulty. Verify the power supply voltage
at the Hirose connector. See "
12-Pin Hirose Connector Signal Details" on page 93 for pinout information.
Communication problems:
• Use a shielded cable where the Hirose connector shell electrically connects the Genie 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 Genie 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 the Genie Ethernet status LED to confirm a gigabit connection. Note that a gigabit connection may still
have many packet resends, rendering the connection useless. This condition has been seen with different NIC
products.
• Use a secured Ethernet cable when the Genie is in a high vibration environment. See "
Ruggedized RJ45
Ethernet Cables" on page 102.
• Check the Ethernet status LEDs on the Genie RJ45 connector. The network speed indicator should show the
expect connection speed 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•DALSA•Sapera LT•Tools•Log Viewer. Start the Genie
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.
