4.6. Advanced Features
For some users enough is never enough. The DSATX has the ability to fine tune many of the parameters
that control its behavior. By using Set and Get commands (‘S’ and ‘G’) it is possible to read and write these
parameters to the DSATX. To use the Set command, type at the prompt, an ‘S’ followed by 2 numbers for the
index, followed by either 4 numbers or 1 number for the value.
Ex:
>S011130 ß Set parameter 1 (LOWVOLTS) to 11.30V
To use the Get command type ‘G’ at the prompt followed by the 2 number index.
Ex:
>G90 ß Get parameter 90 (Program Memory Version)
0108 ß Returns this result (1.08)
4.7. Advanced Feature Tables
The following tables show the available Parameter settings and Queries. Parameters will respond to the
Set and Get command. Queries will only respond to the Get command.
