Wavecard-Waveport User Manual Coronis Systems
For synchronization reasons, even if a remote module responds before the
end of the POLLING_TIME time-out, the next request is sent only after the
time-out.
Low-level commands are used to gather RECEIVED_FRAME_POLLING responses. An index is incremented
upon reception of each polling response. When the WaveCard that initiated the polling exchange is not
longer expecting new responses, it sends its host a first RECEIVED_FRAME_POLLING command, and will
then wait for low-level acknowledgement to decrease its index and send the next
RECEIVED_FRAME_POLLING command.
The following diagram shows the operations carried out by a Wavecard board following reception of a
REQ_SEND_POLLING command:
