Connecting
Before connecting
f
Before connecting, carefully read the operating instructions for the external device to be connected.
f
Turn off the power of all devices before connecting cables.
f
Take note of the following points before connecting the cables. Failure to do so may result in malfunctions.
g
When connecting a cable to a device connected to the projector or the projector itself, touch any nearby
metallic objects to eliminate static electricity from your body before performing work.
g
Do not use unnecessarily long cables to connect a device to the projector or to the projector body. The longer
the cable, the more susceptible to noise it becomes. Since using a cable while it is wound makes it act like an
antenna, it is more susceptible to noise.
g
When connecting cables, connect GND first, then insert the connecting terminal of the connecting device in a
straight manner.
f
Acquire any connection cable necessary to connect the external device to the system that is neither supplied
with the device nor available as an option.
f
If video signals from video equipment contain too much jitter, the images on the screen may wobble. In this
case, a time base corrector (TBC) must be connected.
f
The projector accepts video signals, Y/C signals, YC

signals, analog RGB signals (synchronization
signals are TTL level), and digital signals.
f
Some computer models or graphics cards are not compatible with the projector.
f
Use a cable compensator when you connect devices to the projector using long cables. Otherwise the image
may not display properly.
f
Refer to “List of compatible signals” (
x
page 149) for the types of video signals that can be used with the
projector.
