(2) when the receiver will be used as the wire-less remote controller, please use the signal method the signal format which refer to ?measures to prevent mulfunctioning of ir remote-controlled electric home appliances?. (published july 1987 by association of electric home appliances) if using other signal method, signal format, (ex: signal format which not including the leader signal) the receiver might have chances to miss-function. (3) please set up transmitter?s carrier frequency as same as the receiver?s f 0 frequency. otherwise error might be occurred.
rpm7100 series photo link module 5/6 (4) if transmission signal has non-continues carrier, error might be occurred. continuous carrier is necessary. t1 t2 t1 t2 (5) the receiver was designed to use as in-door use only. therefore, please understand that the receiver cannot cover all characteristics, in case of using it out-door. (6) noise environment (light noise from inverter lamp, and other kind of lamps, power ripple, electromagnetic noise from power circuit, and etc) may cause a reduced effective distance. (7) emitting unit (remote control transmitter) has to be considered about its emitting device function, characteristics and characteristics of the receiver. (8) please connect ?holder? on to the ?ground (gnd)? of pcb. if the holder is not connected to the gnd, there is a possibility of worsening the characteristics of product. (9) do not supply unnecessary stress to lead. (10) please pay careful attention to the lens. it might have a chance to miss-function when the lens get dust or dirty. and also please do not touch the lens. (11) in order to prevent ic from esd, human body and solder iron, etc. are required to be grounded. ! ! ! ! electrical and optical characteristics curves gain : (db) frequency : (khz) fig.6 bpf characteristic 34.00 36.00 38.00 40.00 42.00 ? 10.00 ? 8.00 ? 6.00 ? 4.00 ? 2.00 0.00 1.00 fo=36.0khz fo=40.0khz fo=37.9khz fo=36.7khz rerative sensitivity : (%) wave length : (nm) fig.7 optical bandwidth of the photo-diode encapsulation 700 750 800 850 900 950 1000 1050 1100 1150 1200 0 20 40 60 80 100 120
