Error handling
Whenever the host detects any transmission error, it has
to re-transmit the previous message keeping the same
sequence counter as before.
Whenever the instrument detects any transmission error,
it expects the host to re-transmit the previous message,
keeping the same sequence counter as before. If you
want to skip this retransmission, send a synchronization
request to the instrument, then resume the normal
communication.
Possible transmission errors:
• Incorrect block check sum, i.e. a corrupted message
was received
• Parity error was detected
• General error message (block 99) was received
• Time-out occurred
