User-Interface
Lockout
The syntax for this command is shown below:
:SYSTem
:KLOCK ON | OFF
:KLOCK?
The SYSTEM:KLOCK command and SYSTEM:KLOCK? query are
used to both control and determine the present state of the user-
interface. In certain applications or environments where the 1257
is under automatic control, it may be desired or required that
access to the 1257 be prohibited through the front panel user-
interface.
For example, the command:
SYST:KLOCK ON
will cause the 1257 to display a remote operation screen on the
display with a message indicating that local mode is in a lockout
condition.
The command:
SYST:KLOCK OFF
will also display a remote operation screen, however, the fourth
line will indicate a local option the user can activate by pressing
the fourth line soft key.
To query the present lockout state:
SYST:KLOCK?
will reply with either ON or OFF depending on the present state of
the 1257.
The 1257 operates in either automatic or manual user-interface
