17EnglishBefore connecting● Before connecting cables, carefully read the operatinginstructions for the external device to be connected.● Turn off the power of all devices before connectingcables.● Take note of the following points before connectingthe cables. Failure to do so may result inmalfunctions.• When connecting a cable to the unit or a deviceconnected to the unit itself, touch any nearbymetallic objects to eliminate static electricity fromyour body before performing work.• Do not use unnecessarily long cables to connecta device to the unit or to the unit body. Thelonger the cable, the more susceptible to noise itbecomes. Since using a cable while it is woundmakes it act like an antenna, it is more susceptibleto noise.• When connecting cables, connect GND first, theninsert the connecting terminal of the connectingdevice in a straight manner.● Acquire any connection cable necessary to connectthe external device to the system that is neithersupplied with the device nor available as an option.● If the outer shape of the plug of a connection cableis large, it may come in contact with the plug of anadjacent connection cable. Use a connection cablewith the suitable plug size for the terminal alignment.● If video signals from video equipment contain toomuch jitter, the images on the screen may wobble.In this case, a time base corrector (TBC) must beconnected.● When the sync signals output form PC or videoequipment are disturbed, for example, when changingsettings of video output, the colour of the video maybe disturbed temporarily.● The unit accepts Composite video signals, YC B C R /YPBPR signals, analogue RGB signals and digitalsignals.● Some PC models are not compatible with the unit.● Use cable compensator when you connect devices tothe unit using long cables. Otherwise the image maynot display properly.● Refer to “Preset Signals” (see page 93) for the typesof video signals that can be displayed with the unit.11 IR IN, IR OUT: Infrared Signal Input / OutputTerminalUse this when operating morethan one display with one remotecontrol.It is possible to receive signalfrom the remote control byconnecting the supplied externalIR receiver to the IR IN terminal.(see page 25)12 SERIAL IN,SERIAL OUT:SERIAL Input / Output TerminalControl the Display by connectingto PC.(see page 22)
