Power Failure During A Firmware Update; Cabling And Communication Issues - Dalsa Z-Trak2 2K Series User Manual

Power Failure During a Firmware Update

As a rule, any Z-Trak2/Z-Trak LP2C installation must include the firmware update procedure (see Updating
Firmware via File Access Dialog).
If a power failure occurs during a firmware update, it is unlikely to result in any permanent problems with the 3D
sensor. When electrical power returns and the host computer system has rebooted, follow this procedure.
1. Connect power to the 3D sensor.
The profiler knows that the firmware update failed. The profiler will boot with the previous version of firmware
and operate normally. The Self Status feature (deviceBISTStatus) will report that the last firmware update
failed.
2. Restart the firmware update procedure.

Cabling and Communication Issues

With only two cables connected the 3D sensor, 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 3D sensor 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.
