MM
The MM command reads the menu number of the
display (j in the above table). The MM command
is a read only command.
ML
The ML command reads the menu line of the
display (k in the above table). The ML command
is a read only command.
INTERFACE
CL
The CL command resets the unit to its default
state. The default front panel settings are listed in
the Instrument Setups section. Parameters in the
SETUP and COM menus are not changed. In
addition, the SRQ mask is cleared, and the RS-232
terminating sequence is reset to the proper
defaults.
The command and output buffers are cleared by
the CL command. Therefore, it is bad practice to
use the CL command before all previous
commands have been processed and all responses
have been received. There should never be any
other commands on the same line as a CL
command.
SS { j }
The SS command reads the status byte. (See the
following section for a definition of the status
byte). j designates one bit, 0-7, of the status byte.
If j is included, the designated bit of the status byte
is returned ("0" or "1"). The bit which is read is
then reset. If j is absent, the value of the entire
byte is returned (0-255) and all status bits are then
reset.
SI { j }
The SI command reads the secondary status byte.
(See the following section for a definition of the
secondary status byte). j designates one bit, 0-2, of
the byte. If j is included, the designated bit of the
secondary status byte is returned ("0" or "1"). The
bit which is read is then reset. If j is absent, the
value of the entire byte is returned (0-7) and all
secondary status bits are then reset.
SV { m }
If m is included, the SV command sets the GPIB
SRQ (service request) mask to the value m (0-
255). If m is absent, the value of the SRQ mask is
returned. The SV command may only be sent via
the GPIB interface.
SW { m }
The SW command sets and reads the RS-232
character wait interval. If m is included, the SR400
will wait m times 3.3 ms between characters sent
over the RS-232 interface. This allows slow
computer interfaces to keep up. m can range from
0 to 25. If m is absent, the wait value is returned.
The SW command may only be sent via the RS-
232 interface.
SE { j,k,l,m }
The SE command sets the RS-232 end-of-record
characters sent by the SR400 to those specified by
