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

Economy Mode
,
which determines whether or not the projector shuts itself
off in the absence of an input signal.
When installing the C45XU,
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:

the SmartPanel’s hidden functions, or the Sharp’s remote
control.
