AD-081GE
26
Regarding data transfer rate, a larger packet size produces a slightly lower data transfer
rate. AD-081GE can support a maximum of 16020 byte packets provided the NIC being used
has a Jumbo Frames function with a setting of a 16020 bytes or larger.

Fixed value
Item Unit value
Data Leader Packet Size [Bytes] 90
Data Trailer Packet Size [Bytes] 62
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
The following table shows Bits per Pixel which depends on the pixel format.

G=ROUNDUP {(1024 x 768 x 8 / 8 / (1428-36)) + 2 = 565+ 2 = 567
J={90+62+(1428+18)x(567-2)} x 8 x 30.12 / 1000000 = 196 Mbit/s
