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 112 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 123.
•
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•All Programs•Teledyne 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.
