INTERFACE COMMANDS
*RST
*IDN?
LOCL (?) {i}
OVRM (?) {i}
TRIG
The *RST command resets the SR810 to its default configurations. The
communications setup is not changed. All other modes and settings are
set to their default conditions and values. This command takes some
time to complete. This command resets any data scan in progress. Data
stored in the buffers will be lost.
The *IDN? query returns the SR810's device identification string. This
string is in the format
"Stanford_Research_Systems,SR810,s/n00111,ver1.000".
In this example, the serial number is 00111 and the firmware version is
1.000.
The LOCL command sets the local/remote function. If i=0 the SR810 is
LOCAL, if i=1 the SR810 will go REMOTE, and if i=2 the SR810 will go
into LOCAL LOCKOUT state. The states duplicate the GPIB local/remote
states. In the LOCAL state both command execution and keyboard input
are allowed. In the REMOTE state command execution is allowed but
the keyboard and knob are locked out except for the [LOCAL] key which
returns the SR810 to the LOCAL state. In the LOCAL LOCKOUT state all
front panel operation is locked out, including the [LOCAL] key.
The REMOTE indicator is directly above the [LOCAL] key.
The Overide Remote mode must be set to No in order for the front panel
to be locked out. If Overide Remote is Yes, then the front panel is active
even in the REMOTE state.
The OVRM command sets or queries the GPIB Overide Remote Yes/No
condition. The parameter i selects No (i=0) or Yes (i=1). When Overide
Remote is set to Yes, then the front panel is not locked out when the unit
is in the REMOTE state. The REMOTE indicator will still be on and the
[LOCAL] key will still return the unit to the Local state.
The default mode is Overide Remote Yes. To lock-out the front panel,
use the OVRM0 command before local lock-out.
The TRIG command is the software trigger command. This command
has the same effect as a trigger at the rear panel trigger input.
