V. SPECIAL CONTROL NOTE

Read before attempting to control the projector

The XG-P20XU can be configured with two power saving settings as an Economy Mode. These settings

determine whether (a) the projector shuts itself off in the absence of an input signal; and (b) whether the

projector responds to RS-232 command when in standby (“off) mode.

When installing the P10XU:

• You must set the Economy Mode labeled “MNTR Out/RS232C” to OFF. If you leave this setting

on, the Sharp will not respond to RS-232 control when in standby mode.

• You should set Economy Mode labeled Auto Power Off feature to OFF. If you leave this setting

on, the Sharp will automatically shut itself off when no signal is detected for several minutes. If you

desire automatic shutdown, use the Panel’s Automatic Shutdown Timer.

Economy Mode settings are changed via onscreen menus, Options: Economy Mode. Make sure both

arrows point to the RIGHT, away from the “green leaves.” Access the onscreen menus with either the

SmartPanel’s hidden functions, or the Sharp’s remote control.

Baudrate: The RS-232 port of the XG-P20XU projector can be configured to different baud rates. The

codes used in the projector driver assume the projector is set to 9600 bps (which is the default projector

factory setting). This should be verified using the on-screen menus. In the pulldown menu labeled

“Options” scroll down the RS-232C and select 9600. Press ENTER to save the setting.

Source Selection Switching: Please be aware that because of the way that the XG-P20XU responds to

RS-232 commands to switch sources, there is an unusually long delay in switching between input

sources (approximately 2 seconds). IR control of source selection is not possible for the SmartPanel at

this time.
