a
Display control (Display RS-232/IR) port (-5 VDC to +5 VDC) —
From this port, commands from a projector driver or user-defined command
strings entered via Global Configurator can be sent to the display device.
Connect a cable between the projector or display and the left three poles
(TX, RX, Ground) of this 3.5 mm direct insertion captive screw connector for
bidirectional RS-232 control. The IR Out and Ground pins (the right two
poles
) can be used for one-way infrared signal output to control the display/
projector or some other device, such as a VCR or DVD player. Use the
following illustrations as a wiring guide.
