8.7.3 Fault 2: Lost Packet at the End of the Data Stream
In case of a fault at the end of the data stream, the application will wait for incoming
packets for a predened time. When this time has elapsed, the resend request is trig-
gered and the "lost" packets will be resent.
In our example, packets from no. 3 to no. 5 are lost. This fault is detected after the
predened time has elapsed and the resend request (A) is triggered. The camera then
resends packets no. 3 to no. 5 (B) to complete the image transfer.
8.7.4 Termination Conditions
The resend mechanism will continue until:
▪ all packets have reached the pc
▪ the maximum of resend repetitions is reached
▪ the resend timeout has occured or
▪ the camera returns an error.
