The following are the different acceptable formats of the ST command:
<STX>ST<address><control command><ETX><BCC>
OR
<STX>ST<address><control command><CR>
OR
<STX>ST<address><SP><control command><CR>
OR
<STX>ST<address><SP><control command><ETX><BCC>
The <address> is optional, which means it can be left out completely. The
<address> if present must match the Instrument Address. Additional space
can be present after the <address>.
If the received command does not satisfy the above formats or if the
<address> does not match the Instrument Address the command is ignored.
This is a sample command to switch the instrument to zero mode,
instrument id 5:
<STX>ST005<SP>N<CR>
Data Sampling/Data Query
Command (DA)
This command DA initiates a data transfer from the instrument. The
instrument responds with measurement data, which depends on the range
mode and is listed in
“Measurements Reported in Response to DA
Command for 49i and 49i PS” on page D-7 .
The command structure for a data query command is as follows:
<STX>DA<address><ETX><BCC>
The <address> is optional, which means it can be left out completely. The
<address> if present must match the Instrument Address. Additional space
can be present after the <address>.
If the <address> is left out then no space is allowed in the query string.
A command with no address is also a valid command.
