AM-1600GE / AB-1600GE
23
Note for setting packet size
The packet size is set to 1476 as factory default. Packet size can be modified in the GigE
Vision Transport layer Control section of the camera control tool. For AM-1600GE and AB-
1600GE, users may enter any value for the packet size and the value will be internally
adjusted to an appropriate, legal value that complies with the GenICam standard. Thus,
the actual packet size may be different than the value entered by user.
Regarding the data transfer rate, a larger packet size produces a slightly lower data
transfer rate. The AM-1600GE and AB-1600GE can support a maximum packet size of 16020
bytes if the used NIC has a Jumbo Frames function with setting of 16020 bytes or higher.
The following table shows the list for packet size setting step.

Formula to calculate Data Transfer Rate
J=
{
90+62+(E+18)*(G-2)}*8*D/1000000
Where,
G=ROUNDUP{A*B*C/8/(E-36)}+2
