Aethalometer
Model AE33
$AE33:Xn
Command: $AE33:D1[CR] will return one data line (i.e. 1 byte -> value = 13 so all together
there should be 9 bytes) Please note these are all capital letters.
Important: the command needs to be sent as a string, not as separate characters. In Hyper
Terminal this can be achieved by sending a file with a command. We recommend using FREE
software Real term which has extended functionality regarding send options.
Note: Hyper Terminal may experience problems when sending the string more than two
consecutive identical numbers (111, for example).
Example 1: $AE33:D120[CR] => 11 bytes; Output will be 120 lines of data.
Example 2: $AE33:T20120110120000[CR] will synchronize the time on the Aethalometer to
10 Jan 2012, noon. In case of measuring, stability, clean air or auto clean air test the command
stops the instrument and returns it to the operating state before change. In all the other
instrument states it only changes the time.
