Command (DA)
D-4 Model 5028i Instruction Manual
This is a sample command to switch the instrument to initiate a filter
change, instrument address 14:
<STX>ST014<SP>N<CR>
This command initiates a data transfer from the instrument. The
instrument responds with measurement data, which depends on the
range mode and is listed in
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 14:
<STX>DA<CR>
<STX>DA014<CR>
<STX>DA<SP><14<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>.
