This section specifies how RS-232 and Wired Remote
should be wired to the Sharp projector.
A. RS-232 should be connected to the Sharp control port
labeled RS-232C IN. Connection should be as follows:
1. Wire the Panel to a female DB9 as follows:
RX to 2
TX to 3
GND to 5
JUMPER across 7 and 8
2. Connect this female DB9 to the projector port labeled
RS-232C IN
B. The Wired Remote should be connected to the Sharp
port labeled Wired Remote.
NOTE: If the Panel is wired to the Projector’s Wired
Remote port, the Wired Remote port must be
manually switched to IR on the projector.
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 male
1/8” is not recommended as it makes removal of the
Panel for service more difficult.
2. Attach to the projector port labeled Wired Remote
using a male 1/8” mini to male 1/8” mini (not included).
3. Alternately, replace the male to male cable with the
included the IR Emitter and attach it to one of the IR
windows on the projector. The emitter glows red when
IR is emitted so wiring can be verified.
