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 to a device connected to the projector or to the projector body. The longer the cable, the
more it is susceptible to noise. 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 rst, 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 Video signals containing too much jitter may cause the images on the screen to randomly wobble or wafture. In this case, a time base
corrector (TBC) must be connected.
f The projector accepts video signals (including Y/C signals), analog RGB signals (synchronous signals are TTL level), and digital signals.
f Some computer models 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 175) for the types of video signals that can be used with the projector.
