only. The user may restore local control only by issuing
a

KLOCK OFF

command. The display then returns to

the state that it was in when the 1256 entered lockout
mode. Manual control is also restored if the user cycles
the power to the 1256.

•

Manual lockout:

When the 1256 receives the

command

SYST:KLOCK ON

(local lockout) via the RS-

232 or GPIB interface, it displays the following
message:

*REMOTE OPERATION*

(RS-232 is active)
Local Mode Lockout

In this case, all front-panel controls are disabled. The only way to
restore local (front-panel) control is to send the command

SYST:KLOCK OFF

via the remote (RS-232 or GPIB) interface. For

details on sending the commands

SYST:KLOCK ON

and

SYST:KLOCK OFF

, refer to

Chapter 4: GPIB AND RS-232

INTERFACES

.

The automatic lockout may be enabled or disabled via the front-
panel controls (if local mode is currently active). When lockout is
enabled, the automatic lockout mode is activated when the 1256
receives any command via a remote interface. When lockout is
disabled, the front-panel controls remain active even after the 1256
receives a command (other than

SYST:KLOCK ON

) via the remote

interface. However, the secure lockout mode becomes active if the
1256 receives a

SYST:KLOCK ON

command, regardless of

whether the automatic lockout is enabled or disabled.

To enable or disable the automatic local lockout, proceed as
follows:

1. Press the top key next to the display. Rotate the knob until

the top line reads:

>-----SETTINGS-----<

2. Select line 2 (next to the top line) by pressing the second

key. Rotate the knob until the display reads:

-----SETTINGS-----
> Type: Remote <
Option: Source
Status: GPIB

3.

Select line 3 by pressing the third key. Rotate the knob until
line 3 reads as shown below:

-----SETTINGS-----
Type: Remote
