Demodulator Integrator Comparator Vcc GND GP1U58X Series s Performance Using the transmitter shown in Fig. 1, the output signal of the light detecting unit is good enough to meet the following items in the standard optical system in Fig. 2. ( 1 ) Linear reception distance characteristics When L= 0.2 to 8m, Ee< 10 lx and = 0 in Fig. 2, the output signal shall meet the electrical characteristcs in the attached list. ( 2 ) Sensitivity angle reception distance characteristics When L= 0.2 to 6m, Ee< 10 lx and <= 30 in Fig. 2, the output signal shall meet the electrical characteristics in the attached list. ( 3 ) Anti outer peripheral light reception distance characteristics When L= 0.2 to 4m, Ee<= 300 lx and = 0 in Fig. 2, the output signal shall meet the electrical characteristics in the attached list. 20cm PD49PI 10k + 5V 10 F Transmitter (GL521 used ) Duty 50 % Center frequency (fo ) depends on the attached model list. 10k Vout Oscilloscope Fig. 1. Transmitter In the above figure, the transmitter should be set so that the output Vout can be 40mVPP . However, the PD49PI to be used here should be of the short-circuit current I SC = 2.6 A at E V = 100 lx. (E V is an illuminance by CIE standard light source A( tungsten lamp ) . ) Light detector face illuminance : Ee Vout Reception distance : L Transmitter ( indicates horizontal and vertical directions. ) Fig. 2. Standard optical system GP1U58X Series s Precautions for Use ( 1 ) Use the light emitting unit ( remote control transmitter ) , in consideration of performance, characteristics and operating condition of light emitting device and the characteristics of the light detecting unit. ( 2 ) Pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse. Care must be taken not to touch the light detector surface. If it should be dirty, wipe off with soft cloth so as to prevent scratch. In case some solvents are required, use metyl alcohol, ethyl alcohol or isoprophyl alcohol. Also, protect the light detecting unit against flux and others. ( 3 ) The shield case chall be grounded on PWB pattern. ( 4 ) Do not apply unnecessary force to the terminals and case form outside. ( 5 ) Do not push the light detector surface ( photodiode ) from outside. ( 6 ) To avoid the electorstatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc. ( 7 ) In case of adopting the infrared light detecting unit for the wireless remote control, use it in accordance with the transmission scheme and the signal format recommended in "Countermeasures for malfunction prevention of home appliances with infrared remote control" issued form Japan Association of Electrical Home Appliances ( AEHA ) in July 1987. ( 8 ) As for other general cautions, refer to the chapter" Precautions for Use" |
