Connections18 - ENGLISHBefore connectingz Before connecting, carefully read the operating instructions of the devices to be connected.z Turn off the power of all devices before connecting cables.z Connect the cables by paying enough attention to the following points. If not, troubles may be led.• Before start connecting a cable to the interface box or to a device connected to the interface box, touch ametal to release the charge from the operator’s body.• Do not use unnecessarily long cables when connecting the interface box and the projector. Longer the cableis, easier to be influenced by a noise. If the cable is used in a wrapped condition, it becomes an antenna,which more easily gets influenced by a noise.• When connecting the cable, insert to the connecting terminals of the interface box perpendicularly,connecting to GND first.z If connecting cables necessary for the system connection are not supplied with the devices as accessories ornot available as an option, prepare cables that are compatible to the connecting devices.z Video signals containing too much jitter may cause the images on the screen to randomly wobble or wafture. Inthis case, a time base corrector (TBC) must be connected.z The interface box accepts video signals, S-video signals, analog RGB signals (synchronous signals are TTLlevel), and digital signals.z Some computer models are not compatible with the interface box.z Refer to “List of compatible signals” ( page 48) for the input image signals that can be used for the interfacebox.▶■ terminal pin assignments and signal namesOutside view Pin No. Signal name(1) (2)(3) (4)(1) GND (luminance signal)(2) GND (color signal)(3) Luminance signal(4) Color signal▶■ / terminal pin assignments andsignal namesOutside view Pin No. Signal name(4) and (9) are not used.(5) - (8), (10), and (11) are GNDterminals.(10) (6)(11)(15)(1)(5)(1) R/P R(2) G/G, SYNC/Y(3) B/PB(12) DDC data(13) HD/SYNC(14) VD(15) DDC clock▶■ / terminal pin assignments and signal namesOutside view Pin No. Signal name Pin No. Signal name(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 -Odd-numbered pins (1) to (19) (3) T.M.D.S data 2 - (13) CEC(1)(19)(2)(18)(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/CECGNDEven-numbered pins (2) to (18) (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 +Connections
