The following table specifies the factory-preset input mapping for this Driver. The Configuration Utility

can be used to customize these settings your installation.

Selection 1: VIDEO

Selection 2: S-VIDEO

Selection 3: RGB 1

Selection 4: RGB 2

Input choices available with this Driver are

VIDEO, S-VIDEO, COMPOSITE VIDEO, RGB 1,

RGB 2, and DIGITIAL (DVI).

C. Hidden Function Mapping

The following table specifies the factory preset hidden function mapping for this Driver. The

Volume Up: ADJ UP

Volume Down: ADJ DOWN

Hidden functions names are based on the ViewSonic remote control and projector-top controls.

Menu both summons and dismisses on screen menus. ADJUST controls navigate through onscreen

menus. BLANK, MUTE, and FREEZE are toggles. AUTO IMAGE only works when one of the RGB

inputs is selected.

Hidden functions are accessed by pressing the indicated key while the holding the On key down.

This section specifies how RS-232 and Infrared should be

wired to the ViewSonic projector.

A. RS-232 should be connected to the female DB9

terminal labeled CONTROL. 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 connector to the projector port

labeled CONTROL.

B. The IR Emitter should be connected to the one of the

ViewSonic 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.

III. TROUBLESHOOTING

Additional tips can be found in the SmartPanel Configuration and Installation Guide.

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 verification indicates that the projector is off. Check to make

sure the RS-232 connection is correctly wired. If a third party power current sensor is being used,

make sure correctly wired and calibrated. The most common cause for power polling failure when

other control works, is that the RX line is incorrectly wired or soldered.

The projector keeps turning itself off, though the Panel is on (then the Panel then shuts itself off).

The ViewSonic may be configured through the OPTIONS (OPT.) menu to shut itself off in the

absence of a valid input signal. Refer to the ViewSonic manual for more information. Also, ensure

that Panel is not configured with an unexpected value for Inactivity Shutdown.

When I try to turn the projector on, the warming indicator (red LED) blink.

The projector is in lockout mode, 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 ViewSonic power off, the Panel will usually detect this condition and

power off within thirty seconds. Should the ViewSonic power on, the Panel will usually detecting this

condition and power on within fifteen seconds.

2. This ViewSonic is currently controlled via a combination of Infrared and RS-232 only. Wired Remote

is not an option as the ViewSonic does not have a Wired Remote port.

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

ViewSonic will not allow power to be restored before a minimum delay has expired. Therefore,

disabling the lockout delay will cause potentially confusing Panel behavior.
