Display Control

For security reasons, you may want to turn off the front-panel display. From

the remote interface, you can display a 12-character message on the front

panel.

The display can be enabled / disabled from the remote interface only.

• When the display is turned off, outputs are not sent to the display and all

annunciators are disabled except the

ERROR

annunciator. Front-panel

operation is otherwise unaffected by turning off the display.

• The display state is stored in

volatile

memory; the display is always enabled

when power has been off, after a remote interface reset, or after returning to

local from remote.

• You can display a message on the front panel by sending a command from the

remote interface. The power supply can display up to 12 characters of the

message on the front panel; any additional characters are truncated. Commas,

periods, and semicolons share a display space with the preceding character,

and

are not

considered individual characters. When a message is displayed,

outputs are not sent to the display.

• Sending a message to the display from the remote interface overrides the

display state; this means that you can display a message even if the display is

turned off.
The display state is automatically turned on when you return to the local (front

panel) operation. Press

key to return to the local state from the remote

interface.

• Remote interface operation:

DISP {OFF|ON}

Disable / enable the display

DISP:TEXT <quoted string>

Display the string enclosed in quotes

DISP:TEXT:CLE

Clear the displayed message

The following statement shows how to display a message on the front panel

from a Agilent Technologies controller.

"DISP:TEXT ‘HELLO’ "
