This section specifies how IR-Emitter should be wired to
the Sharp projector.
A. The IR Emitter should be connected to the one of the
Sharp IR windows as follows:
1. Wire the Panel to a female 1/8” Mini as show; wire
IR/SER to tip and GND to ring. Splicing and direct
wiring to the IR Emitter is not recommended as it
makes removal of the Panel for service more difficult.
2. Connect the included IR Emitter to the female mini.
3. Affix the IR Emitter to one of the IR windows on the
projector.
Note that the emitter glows red when IR is emitted so wiring
can be verified.
Additional Projector Settings:
There are settings on the Sharp PG-M20x projector that will
affect how the SmartPanel will work. In order to receive the
best performance, set the following options to OFF in the
projectors menu screens.
Press the MENU button either using the SmartPanel hidden
functions or the Sharp remote control. Then change the
following settings.
1. In the Options menu screen turn Auto Power Off to OFF
2. In the Options menu screen turn the Power Save to OFF
3. In the Options menu screen turn the Auto Search to OFF

III. TROUBLESHOOTING
Addition tips can be found in the SmartPanel Configuration and Installation Manual.
The Panel does not do anything at all.
When power is applied to the Panel it should run through a brief power on self-test, during which all of
the Panel lights will turn on and off in sequence. If you do not see this self test, make sure power is
connected correctly and that polarity is correct.
The Panel keeps turning itself off even though the projector is on.
The Panel turns itself off when power polling indicates that the projector is off. Check to make sure
the RS-232 connection is correctly wired (it is extremely unlikely other control would work, and power
polling not).
When I try to turn the projector on, the warming indicator (red LED) blink.
The projector is in the default configured lockout state, and the Panel is waiting for its internal lockout
timer to expire. This feature protects the projector’s bulb. Be sure to let your client know about this
behavior.
IV. TECHNICAL NOTES
1. By default, projector power is verified by polling every few seconds via the RS-232 port. Power
polling can be suspended by depressing and holding the On key; polling will be restored when the
key is released. Should the Sharp power off, the Panel will usually detect this condition and power
off within twenty seconds. Should the Sharp power on, the Panel will usually detecting this condition
and power on within ten seconds.
2. The Sharp is controlled via both IR/Wired Remote and RS-232. We recommend Wired Remote
control as it is generally more robust. However, use of the Wired Remote will prevent use of the
Sharp’s remote control. A complete discussion of the relative advantages of IR vs. Wired Remote
can be found in the SmartPanel Configuration and Installation Manual.
3. The lockout timer specifies the amount of time allowed between sending POWER OFF and POWER
ON to the projector (the delay allows the projector bulb to cool before re-powering). This delay can
be configured using the Configuration Utility; however, adjusting the lockout timer delay is
strongly discouraged as rapid re-powering causes undue wear on the projector’s bulb. Also, the
Sharp will not allow power to be restored before a minimum delay has expired. Therefore,
disabling the lockout delay will cause potentially confusing Panel behavior.
