After "getting" the Analog channels, send the following commands to return the data
from the CBL 2 to the host:
Command Syntax:
{12,41,6}
{12,41,0}
{12,41,.1,Start,Stop}
Additional Notes on Command 12
A few additional things to be aware of when using Command 12:
When Command 12 is used, the power generally stays on all during sampling. (This
is because the processor must look for the data at all times during the sample
interval and not just at the sample times.) As a result, this mode tends to deplete
the batteries very quickly.
The number of data samples taken is limited only by the available memory after
memory is reserved for the Command 1 channels that are set up. The CBL 2 has about
12,000 available memory locations. If X channels are setup and Y samples are selected
using Command 3, the number of samples on CH 41 is limited to (12,000 – X...Y)/3.
You absolutely must have at least one analog channel activated before sending the
Command 3 to start sampling. You must do a GET of the analog data (to force the
calculator to wait for the end of sampling) before retrieving the Command 12
CH 41 data.
Command 102
Syntax: {102, pwrctl }
Power Control
.1 = Always ON; will automatically power down (APD) if running on batteries.
0 = Normal mode
1-1000 = Powers up this many seconds before data taken

collect data in rotary motion mode; send before
Command 3
