This camera is set to communicate with a jumbo packet (jumbo frame) size of 8192 bytes.
Please use a network card that supports jumbo packets (jumbo frame support).
If the network card does not support communication with 8192 bytes of jumbo packets, sufficient communication
performance may not be exhibited and the received frame rate may be lower than the set frame rate.
Jumbo packets for PC can be set in "Network Adapter" of Device Manager.
Select Jumbo Packet and set its value to a value greater than or equal to 8192 (9014 bytes or 9k).
If there is no jumbo packet setting item, by downloading and installing the driver for the network adapter from the
manufacturer's website, the jumbo packet function may be available.
・How to check the communication packet size on Sphinx GEV Viewer
Launch Sphinx GEV Viewer and select "Transport Layer Control"-> "Stream Channel Selector"-> "Packet
Size" in the "Parameter" field. Value is the packet size.
If this Value is 8192, communication is possible with a sufficient packet size. If this Value is less than 8192
(such as 1500), review the jumbo packet settings.
