Example 2: When reading data after making measurement three times in the
Manual Trigger mode, send “MTG ; MTG ; MTG.” Then read data
three times or repeat data readout.
[Notes]
1. Caution for output queue readout
When reading data from the output queue, the DSM-8104 adds a delimiter to each data
group.
All the data which was taken in one readout to the output queue by the reading of taking
can be read.
For this reason, the MAV bit is used to check data presence.
2. Caution when continually executing commands
When executing commands that have response data, send the commands in one line by
separating them by “;” as shown earlier.
3. Necessity for detection of end of command processing
The DSM-8104 cannot receive a next command while processing a command that has
been received earlier. If a command is received while reception is disabled, handshake
is temporarily performed and NRFD is locked in a receive disable state till reception is
enabled, to let the talker wait. This means that a bus is exclusively owned till
processing of the DSM-8104 ends and the system speed becomes slow. For these
reasons, detection of end of processing is necessary.
