For security reasons, or to speed up the rate at which the 81150A / 81160A
can execute commands from the remote interface, you may want to turn off
the front-panel display. From the remote interface, you can also display a 12-
character message on the front panel.
The display can be disabled from the front-panel. Press , then
System, and then the Display Off softkey. Pressing any key or turning
the Rotary Knob will turn the display on.
When disabled, the front-panel display is blanked.
Sending a message to the front-panel display from the remote
interface overrides the display state. This means that you can display
a message even if the display is currently disabled.
The display is automatically enabled when power is cycled.
You can display a text message on the front panel by sending a
command from the remote interface. You can use upper- or lower-
case letters (A-Z), numbers (0-9), and any other character on a
standard computer keyboard. Depending on the number of characters
that you specify, the 81150A / 81160A will choose one of two font
sizes to display the message. You can display approximately 12
characters in a large font and approximately 40 characters in a small
font.
When the display is blanked, then all the LEDs at the front-panel keys
are also turned off (except the power key).
