This section specifies how RS-232 and Infrared should be
wired to the Viewsonic projector.
PROJECTOR CONTROL
Female HD15
TX to pin 13
RX to pin 14
GND to pin 10
A. RS-232 should be connected to the female HD15
terminal labeled CONTROL. Connection should be as
follows:
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
GND

1.
Wire the Panel to a female HD 15 as follows:
TX to 13
RX to 14
GND to 10
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.
