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
