Block Reception Processing
Continuous request sequence
This sequence uses only commands to periodically request measurement
data.
The DRD command follows this pattern.
The sound level meter periodically sends out blocks.
To stop the process, the stop request command <
SUB
> is sent from the com-
puter. Any other command is disregarded by the sound level meter.
The block sending process continues indefi nitely as long as the <
SUB
> com-
mand is not received.
