The Host may enable the option to enforce acknowledgement of every serial message transacted with the Module, specifically by issuing the /wiki/spaces/RZ3/pages/77037599Serial ACK Config Write command to the Module. The serial acknowledgment option is disabled by default. If this option is disabled when the Host sends a command, a /wiki/spaces/RZ3/pages/77037599Status Response will only be issued upon an error; i.e., a Status Response of “Success” will not be issued by the Module upon successful completion of the command. This model has been designed to minimize serial traffic.
...
- A specific response is returned, e.g., a Read Response to a Read Request, with a matching Frame Sequence Number as the request.
- A general /wiki/spaces/RZ3/pages/77037599Status Response is returned with success or error information, with a matching Frame Sequence Number as the frame that is being acknowledged.
...
The Module queues all outgoing serial messages to the Host. If the Host has enabled the Serial Acknowledgment option, the Module will retransmit any message up to (3) times until that message is acknowledged. The acknowledgement must be of the /wiki/spaces/RZ3/pages/77037599Status Response type, with a Frame Sequence Number that matches the frame being acknowledged.
