Troubleshooting
Z-Trak2 3D Profiler Sensors
Cabling and communication issues
With only two cables connected the Z-Trak2, cabling issues are limited.
Power supply problems
•
If the profiler status LED is off, the DC supply power is not connected or faulty. Verify the
power supply voltage.
Communication Problems
•
If using the I/O cable to connect a power supply, use a shielded cable where the connector shell
electrically connects the Z-Trak2 to the power supply earth ground. This can eliminate trigger
issues in a high EMI environment.
•
Check that the Ethernet cable is clipped to the sensor on one end, and to the NIC or switch on
the other end.
•
Verify that all Ethernet cables are CAT6 and in good condition. This is very important with long
cable lengths. Poor cables will cause connections to auto-configure at lower speeds.
•
Check the Ethernet status LEDs on the NIC used with the device. The Link Status indicator is on
and the activity LED should flash with network messages.
•
When using very long cables, up to the maximum specified length of 100 m 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
Sapera Log Viewer
tool to check on packet resend conditions. There should be no
packet resend
messages, else this indicates a control or video transmission problem due to
poor connections or extremely high EMI environments. The Log Viewer tool can be found on the
Windows
Start
menu, under
Teledyne DALSA Sapera LT

Low connection speed after camera reset
with Intel X550 T2 NIC
When connected directly to the Intel X550 T2 NIC (not through a switch), following a camera reset
and subsequent link speed negotiation, the GigE link speed is set to 1 GigE instead of higher
speeds (5 GigE or 2.5 GigE).
To correct the problem, connect to the Intel X550 T2 through a 5G capable switch, or replace the
NIC with a different model, such as the ASUS XG-C100C, which does not exhibit this behavior.
