5.7 Send Data Command (aD0!)

This command is used to get groups of data from the Levelogger. An aD0! command is issued by the data logger after a M, MC, C, CC, or V command. The Levelogger responds by sending the data. For a Solinst Levelogger, this is currently two data items: temperature and level measurements, and possibly a third measurement depending on the type of Levelogger. A typical command/reply is:

0D0!0+24.2981+0.35212<CR><LF> where the temperature is “+24.2981” in Degrees Celsius and the level is “+0.35212” in meters.

In response to a checksum request i.e. MC, CC; a typical command/reply is: 0D0!0+24.2981+0.35212MQ_<CR><LF> where the temperature and level are as before, and the final “MQ_” is the checksum. The aD1 to aD9 commands are reserved for future use.
