6.1.2  CPT6020 Commands and Queries

Commands with complex outputs are explained In tables following the command set.

The following convention is used for the following command set tables:

n – 1 placeholder for digits and decimal point

C – 1 character placeholder for alpha character A-Z

<cr> - carriage return – ASCII 13

<lf> - line feed – ASCII 10

± - 1 place holder for a + or – sign, or blank which i

¬<sp> - 1 place holder for a space

X – address placeholder or ‘*’ for universal queries to be sent to all instruments

Y(1,2,3…) – strings as defined in description

<yy,mm,dd> -  Last two digits of year, month, day. 

All commands, queries, and responses will be terminated with a <cr><lf>.

All commands that are password protected are designated with “(Password Protected)” in the Query column below.
