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 address 5:
<STX>ST005<SP>N<CR>
This command nitiates 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
” below.
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.
The following are the different acceptable formats of the DA command
with Instrument Address 5:
<STX>DA<CR>
<STX>DA005<CR>
<STX>DA<SP><SP>5<ETX><BCC>
<STX>DA<ETX><BCC>
The data query string is valid and will be answered with data transmission
only if the command starts with <STX>, which is followed by the
characters DA, and the <address> (if present) matches the Instrument
Address, and the command is terminated with either <CR> with no
checksum or <ETX>, followed by the correct checksum <BCC>.
