Chapter 2 Getting Started — ConnectingENGLISH - 29ConnectingBefore connectingf 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 staticelectricity 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, themore 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 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 either not supplied with the device or notavailable 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 basecorrector (TBC) must be connected.f The projector accepts video 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 130) for the types of video signals that can be used with the projector. terminal pin assignments and signal namesOutside view Pin No. Signal name Pin No. Signal name(10)(6)(11) (15)(1) (5)(1) R/P R (9) ―(2) G/Y (10) GND(3) B/P B (11) GND(4) ― (12) DDC data(5) GND (13) SYNC/HD(6) GND (14) VD(7) GND (15) DDC clock(8) GND-I IN> terminal pin assignments and signal namesOutside view Pin No. Signal name Pin No. Signal name(9)(17)(24)(1)(8)(16)C4C1C3C2C5(1) T.M.D.S data 2- (16) Hot plug detection(2) T.M.D.S data 2+ (17) T.M.D.S data 0-(3) T.M.D.S data 2/4 shield (18) T.M.D.S data 0+(4) ― (19) T.M.D.S data 0/5 shield(5) ― (20) ―(6) DDC clock (21) ―(7) DDC data (22) T.M.D.S clock shield(8) Analog VD (23) T.M.D.S clock+(9) T.M.D.S data 1 - (24) T.M.D.S clock-(10) T.M.D.S data 1+ C1 Analog R/P R(11) T.M.D.S data 1/3 shield C2 Analog G/G SYNC/Y(12) ― C3 Analog B/P B(13) ― C4 Analog HD/SYNC(14) +5 V C5 Analog GND(15) GND
