8.2.2 Video data rate (network bandwidth)
The video bit rate for BM-141GE and BB-141GE at the continuous mode is:
Model
Pixel Type
Packet data volume
(In case the Packet size is 1428)
BM-141GE
MONO8
362 Mbit/s
MONO10_PACKED
MONO12_PACKED
544 Mbit/s
MONO10/MONO12
725 Mbit/s

BAYRG8,BAYGB8
362 Mbit/s
BAYRG10,BAYBG10
BAYRG12,BAYGB12
725 Mbit/s
In the case of using Jumbo Frames, the packet data will be improved by 2 %.
For BM-141GE and BB-141GE, the jumbo frame size can be a maximum 16384 Bytes (factory
setting is 1428 Bytes). The NIC must also be set to support Jumbo Frames(see chapter 8.2.4).
Based on the Pixel Type, the packet size may be automatically adjusted inside the camera to
its most suitable value .
8.3.3 Note for setting packet size
The packet size is set to 1428 as the factory default. 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. The packet size can be modified in the GigE
Vision Transport Layer Control section of the camera control tool.
Regarding data transfer rate, a larger packet size produces a slightly lower data
transfer rate. The BM-500GE and BB-500GE series can support a maximum of 4040 byte
packets provided the NIC being used has a Jumbo Frames function with a setting of a
4040 bytes or larger.
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.
