ACT_TIMER to Set messages - E1.20 RDM (Remote Device Management) Protocol Forums

Nic,

The examples were all done using GET_COMMAND message transactions but from Table 6-7 you'll see that ACK_TIMER is valid for SET_COMMAND_RESPONSE messages as well.

The Command Class Response should always be a mirror of what it received. i.e. SET_COMMAND will always be a SET_COMMAND_RESPONSE, GET_COMMAND will have GET_COMMAND_RESPONSE and DISCOVERY_COMMAND a DISCOVERY_COMMAND_RESPONSE.

I can't think of any case where we break that symmetry.

my question is about TIMER ACK. For case when my device need time to save DMX START ADDRESS to eeprom:

1)controller: SET_COMMAND DMX_START_ADDRESS
1)responder: SET_COMMAND_RESPONSE TIMER_ACK 2
wait 200ms
2)controller: GET_COMMAND QUEUED
2)responder: SET_COMMAND_RESPONSE ACK or GET_COMMAND_RESPONSE ACK?
SET if answer for transaction 1 or GET for transaction 2 what is correct?
and number of transactions for this case is 1 (for all this chart with same transaction number) or 2 (split it into 2 steps)? transaction it is send/receive or full done target operation?
