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
to return to the local state from the remote interface.
