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.
