You can calculate the frame readout time by using this formula:
Frame Readout Time = ( (AOI Height + 1) x C
1
) + C
2
Where the values for the constants C
1
and C
2
are from the table in Section 9.12 on page 144 for all
camera models.
For more information about the AOI height, see Section 11.6 on page 185.
You can calculate an approximate frame transmission time by using this formula:
Note that this is an approximate frame transmission time. Due to the nature of the Ethernet network,
the transmission time could vary. Also note that the frame transmission cannot be less than the
frame readout time. So if the frame transmission time formula returns a value that is less than the
readout time, the approximate frame transmission time will be equal to the readout time.
Due to the nature of the Ethernet network, the transmission start delay can vary from frame to
frame. The transmission start delay, however, is of very low significance when compared to the
transmission time.
For more information about the Payload Size and Device Current Throughput parameters, see
Section 5.1 on page 39.
