TX to 2

RX to 3

GND to 5

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

support at [email protected].

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.
