RS-232-C Interface
12.4 Format and Commands of Output Data (before
the IEEE488.2-1987 Standard)
Output Format
The format of output data is the same as for the GP-IB interface. Refer to page 11-4 for more
details.
Commands
The commands used for the RS-232-C interface are identical to those used for the GP-IB
interface, except for the following commands.
DL/DL?
Sets or inquires about output data terminator.
SyntaxDLm <terminator>
“m” indicates terminator
m= 0 : CR + LF
1 : LF
2 : CR
Query DL?<terminator>
Example DL1
Note
If a value outside the setting range is set, an error code will appear.
The interface message function of the GP-IB interface is assigned to the following commands at
the RS-232-C interface.
<ESC>S
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).
<ESC>R
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
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
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).
