Connect this female DB9 to the included Sharp intermediate cable (labeled RS-232C) and connect
the mini-DIN end of the adapter to the projector port labeled RS-232C IOIOI.
2. Infrared Emitter:
Wire the Panel IR/Serial port to a female 1/8" Mini as follows:
IR/SER to tip
GND to ring
Connect to the included IR Emitter and attach the emitter bud to any projector IR window.
III. Additional Projector Information
The A20X can be configured with an Economy Mode, which determines whether or not the projector
shuts itself off in the absence of an input signal.
When installing the A20X, you should set the Economy Mode to OFF. This disables the Sharp’s
Automatic Power Shutoff feature.
Economy Mode is set via on screen menus, Options: Economy Mode. Access the onscreen menus with
either the SmartPanel’s hidden functions, or the Sharp’s remote control.

This section specifies how RS-232 and the Infrared Emitter
should be wired to the Sharp projector.
A. RS-232 should be connected to the Sharp control port
labeled RS-232C. Connection should be as follows:
1. Wire the Panel to a female DB9 as follows:
TX to 2
RX to 3
GND to 5
2. Connect this female DB9 to the Sharp’s custom DB9 to
mini-DIN adapter cable. This cable is included with the
Sharp and is labeled RS-232C.
3. Connect the Sharp custom cable to the projector port
labeled RS-232C IOIOI.
B. Infrared should be wired to any Sharp infrared port.
Connection should be as follows:
1. Wire the Panel to a female 1/8" Mini as shown; wire
IR/SER to tip and GND to ring. Direct wiring to the IR
Emitter is not recommended as it makes removal of the
Panel for service more difficult.
2. Attach to any projector IR port using the Panel’s IR
Emitter (included with the Panel).
Note that the emitter glows red when IR is emitted so wiring
can be verified.
SPECIAL CONTROL NOTE
Read before attempting to control the projector
The A20X can be configured with an Economy Mode,
which determines whether or not the projector shuts itself
off in the absence of an input signal.
When installing the A20X, you should set the Economy
Mode to OFF. This disables the Sharp’s Automatic
Power Shutoff feature.
Economy Mode is set via on screen menus, Options:
Economy Mode. Access the onscreen menus with either
the SmartPanel’s hidden functions, or the Sharp’s remote
control.
Questions should be directed to SP Controls technical
SmartPanel Projector Driver Application Note Sharp PG-A20X
III. TROUBLESHOOTING
Additional tips can be found in the SmartPanel Configuration and Installation Guide.
The Projector keeps turning itself off!
Verify that the A20X’s Economy Mode is set to OFF as explained in the Special Note in the Control
Wiring section of this document. If the Economy Mode is on, the projector will shut itself off after
fifteen minutes. If power polling or a third party power current sensor is being used (e.g., AMX-PCS),
the Panel will automatically shut itself off also. If not, the Panel will remain on and you will have to
power the Panel off with the Off button and wait until the lockout timer expires before you can re-
power the projector.
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 status feedback indicates that the projector is off. If a third
party power current sensor is being used, check to make sure that it is correctly wired, and that it is
correctly calibrated according to the manufacturer’s instructions. If not, make sure that the Panel is
configured with None or Power Polling under power status feedback in the Configuration Utility’s
Wiring Options tab.
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 RS-232 and Infrared/Wired Remote with this Driver. A discussion of the
advantages of Wired Remote versus IR can be found in the SmartPanel Configuration and
Installation Guide.
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.
