LUCID Vision Labs recommends enabling jumbo frames on your Ethernet adapter. A jumbo frame is an Ethernet frame that is larger than 1500 bytes. Most Ethernet adapters support jumbo frames, however it is usually turned off by default.
Enabling jumbo frames on the Ethernet adapter allows a packet size of up to 9000 bytes to be set on the Atlas. The larger packet size will enable optimal performance on high-bandwidth cameras, and it usually reduces CPU load on the host system. Please note in order to set a 9000 byte packet size on the camera, the Ethernet adapter must support a jumbo frame size of 9000 bytes or higher.
The following table are some of the Ethernet adapters that LUCID Vision Labs has tested:
Product Name | Maximum Jumbo Frame Size |
---|---|
ADLINK PCIe-GIE64+ | 9000 |
Neousys PCIe-PoE354at | 9500 |
Intel EXPI9301CT (non-POE) | 9000 |
ioi GE10P-PCIE4XG301 | 16000 |
ioi DGEAP2X-PCIE8XG302 | 16000 |
If you still experience issues such as lost packets or dropped frames, you can also try:
- Updating the Ethernet adapter driver (you may need to enable jumbo frames again after updating).
- Increasing the receive buffer size in your Ethernet adapter properties.
- Reducing the DeviceLinkThroughputLimit value (this may reduce maximum frame rate).
