AD-131GE
38
9.3.2 Video data rate (network bandwidth)
The video bit rate for the AD-131GE in Continuous mode is:
In the case of using Jumbo Frames (16K), the packet data will be improved by 2%.
Note for setting packet size
The packet size is set to 1476 as the factory default. Packet size can be modified in the GigE
Vision Transport Layer Control section of the camera control tool (see below). For AD-131GE,
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 the user.
Caution: do not set the packet size larger than the maximum setting available in the NIC or
switch to which the camera is connected. Doing so will cause output to be blocked.
The following table shows possible packet size on each pixel format.
Pixel format

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
