Range XL-GL Drops Frames or Fails to Receive Complete Data During Acquisition
Symptom
When acquiring data with Range XL-GL, you may frequently lose frames or fail to receive all the data.
Possible Causes
-
The network link does not provide Gigabit Ethernet.
-
Jumbo frames are not enabled on the computer’s network port.
-
The computer’s network adapter does not provide sufficient receive performance.
Solution
| The procedures in this section that require operations on the computer apply only to Windows. If you use Ubuntu, contact Technical Support. |
Follow these steps to troubleshoot the issue:
-
Check whether the network link between Range XL-GL and the computer provides Gigabit Ethernet.
-
If not, replace the switch, router, network adapter, or cable with one that supports Gigabit Ethernet. Connect Range XL-GL directly to the computer if possible. Then check whether the issue persists.

If the issue is resolved, troubleshooting is complete.
-
If the issue persists, go to Step 2.

-
If it does, go to Step 2.
-
-
Check whether jumbo frames are enabled on the computer’s network port connected to Range XL-GL. For details, see Enable Jumbo Frames.
-
If not, enable jumbo frames and check whether the issue persists.
-
If the issue is resolved, troubleshooting is complete.
-
If the issue persists, go to Step 3.
-
-
If they are enabled, go to Step 3.
-
-
Check whether the computer’s network adapter can receive data at the required rate and has sufficient bandwidth.
-
If it does not, replace the network adapter. If you need to add a network port, use a native PCIe network adapter where possible. Then check whether the issue persists.
-
If the issue is resolved, troubleshooting is complete.
-
If the issue persists, go to Step 4.

If a longer acquisition time is acceptable, increase the packet delay parameter
GevSCPDthrough the Mech-Eye API. Start at 10 μs and adjust it gradually based on acquisition stability and time. Then check whether the issue persists.scanner.currentUserSet().setIntValue("GevSCPD", 10000); // 10000 ns = 10 μsGevSCPDcan currently be set only through the API. Set it before starting acquisition. If the longer acquisition time affects the production cycle, improve the network environment first, for example by replacing the network adapter or optimizing the network connection.-
If the issue is resolved, troubleshooting is complete.
