5. Press the

Local, Remote and
Local Lockout
Local mode
6-2 Programming
In this mode the RMT LED is off, the front panel is used to operate
the instrument and programming messages are ignored.
You can select local mode in the following ways:
•
Switching the HP 8 1 12A on.
•
Pressing the
key, if Local Lockout is inactive.
•
Sending an HP-IB Local command to the instrument from the
system controller (use the LOCAL statement in BASIC 5.0/5.1).
LOCAL 712
The output signal and
all
instrument settings remain unchanged
following a change from remote to local mode.
Remote mode
In
this mode the RMT LED is illuminated and programming
messages received via the HP-IB are interpreted (parsed) and used to
control the instrument . The front panel controls are disabled apart
from:
•
The
switch.
•
The trigger LEVEL adjust knob.
•
The
key, if Local Lockout is inactive.
You can select remote mode by sending an HP-IB Remote Enable
command from the system controller (use the REMOTE statement in
BASIC 5.0/5.1).
REMOTE 712
The output signal and all instrument settings remain unchanged
following a change from local to remote mode.
Local Lockout
The
key can be disabled by sending an HP-IB Local Lockout
command from the system controller (use the LOCAL LOCKOUT
statement in BASIC 5.0/5.1).
LOCAL LOCKOUT 712
This ensures that only the system controller can return the
instrument to Local mode, except when the instrument is switched
off and on again.
It is recommended that all programming applications use this facility,
because if a programming message is interrupted by pressing the
key during data transmission from the system controller, the
HP 81 12A may be left in an unknown state.
