NCR Customer Display NCR 5972 - Manual (Page 36)

4-6 Chapter 4: Programming Set Up
Set Display State On
Format: 1B 05
Description: This state is used for normal run‐time conditions.
This operation instructs the firmware to leave one of the other
states and begin performing normal refresh operations. There may
be a slight delay before the Vacuum Fluorescent Display (VFD)
reaches the specified brightness setting when exiting the Low
Power State. This delay should not exceed 1 second from the time
the command is received until the time the VFD reaches the
specified brightness.
The Screen Save feature may be in force during the Display On
state. This means that after about five minutes of no new display
activity, the Screen Save feature could take over and cause the
display to go blank or begin walking from right to left.
Set Low Power State On
Format: 1B 06
Description: This state is used to reduce Retail Display power
consumption and extend the life of the Retail Display VFD. Power
is removed from the display, but the Retail Display controller is still
fully operational and continues to accept commands. This
command causes the firmware to blank or turn off the Retail
Display. Display data can be processed while the display is in the
Low Power State, but it does not appear until the Low Power State
is changed. The displayed characters are preserved so that upon
leaving the Low Power State, the display is restored. To leave the
Low Power State, one of the other state commands must be
received. This is the default state for the Retail Display after power‐
up.
