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 displ ay can be
enabl ed / disabl ed
from the remote interface only.
• When the displ ay is turned off, outputs are not sent to the display and all
annunciators are disabl ed except the
ERROR
annunciator. Front-panel
operation is otherwise unaffected by turning off the display.
• The display state is stored in vola tile 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 fro nt panel; any additional characters are truncated.
Commas, periods, and semicolons share a display spa ce with the prec eding
character, and are not considered individual characte rs. Whe n 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
(
Local
) 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
