11.4 Format and Commands of Output Data (before
the IEEE488.2 Standard)
Output Format
The format of output data is the same as the GP-IB interface. Refer to section 10.4 for
more details.
Commands
The commands used in serial communications on the WT210/WT230 are common with
GP-IB commands. However, the following commands are different.
DL/DL?<terminator>
Sets or inquires about output data terminator.
Syntax DLm <terminator>
“m” indicates terminator
m=0: CR + LF
1: LF
2: CR
Query DL?<terminator>
Example DL1
In the serial communications on the WT210/WT230, the GP-IB interface message
functions are assigned to the following commands.
<ESC>S<terminator>
Equivalent to GP-IB’s serial poll function. Status byte is output when the S command
is received following reception of the <ESC> code (1BH).
For a description of the status byte format, see section 10.3. However, in the serial
communications of the WT210/WT230, SRQ (DI07) is always 1.
<ESC>R<terminator>
Equivalent to GP-IB’s remote/local control function. The instrument is placed in
remote status and panel keys become invalid when the R command is received
following reception of the <ESC> code (1BH). Press the LOCAL key to exit from the
remote status.
<ESC>L<terminator>
Equivalent to GP-IB’s remote/local control function. When the instrument is in remote
status, the instrument will be placed in local status when the L command is received
following reception of the <ESC> code (1BH).
<ESC>C<terminator>
Equivalent to GP-IB’s device clear function. The communication devices of this
instrument are initialized when the C command is received following reception of the
<ESC> code (1BH).
