Chapter 2 Getting Started — Connecting46 - ENGLISHConnectingBefore 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 a device to the projector or to the projector body. The longer the cable, the moresusceptible 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 availableas 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 If synchronization signals output from computers or video equipment are disrupted due to changes in the video output setting or otherreasons, colors of projected images may be temporarily disrupted.f The projector accepts video signals, Y/C signals, YCBCR /YPBPR signals, analog RGB signals (synchronization signals are TTL level), anddigital 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 176) 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 terminal pin assignments and signal namesOutside view Pin No. Signal name Pin No. Signal nameEven-numbered pins of (2) to (18)(1) (19)(2) (18)Odd-numbered pins of (1) to (19)(1) T.M.D.S data 2+ (11) T.M.D.S clock shield(2) T.M.D.S data 2 shield (12) T.M.D.S clock-(3) T.M.D.S data 2- (13) CEC(4) T.M.D.S data 1+ (14) —(5) T.M.D.S data 1 shield (15) SCL(6) T.M.D.S data 1- (16) SDA(7) T.M.D.S data 0+ (17) DDC/CECGND(8) T.M.D.S data 0 shield (18) +5 V(9) T.M.D.S data 0- (19) Hot plug detection(10) T.M.D.S clock+
