IRM-37xxT SERIES Test Method： The specified electro-optical characteristics is satisfied under the following Conditions at the controllable distance. cMeasurement place A place that is nothing of extreme light reflected in the room. dExternal light Project the light of ordinary white fluorescent lamps which are not high Frequency lamps and must be less then 10 Lux at the module surface. (Ee≦10Lux) eStandard transmitter A transmitter whose output is so adjusted as to Vo=400mVp-p and the output Wave form shown in Fig.-1.According to the measurement method shown in Fig.-2 the standard transmitter is specified. However , the infrared photodiode to be used for the transmitter should be λp=940nm,Δλ=50nm. Also, photodiode is used of PD438B(Vr=5V). (Standard light / Light source temperature 2856°K). fMeasuring system According to the measuring system shown in Fig.-3 Block Diagram： Vs IN Input Oscillator CGA & filter OUT Demodulator µC AGC/ATC & digital control Carrier frequency f0 Modulated IR signal min 10 pulses GND Everlight Electronics Co., Ltd. http:\\www.everlight.com Device No：SZDMO-037-031 Prepared date：31-August-2007 Rev 1 Page: 4 of 10 Prepared by： Liuyan EVERLIGHT ELECTRONICS CO.,LTD.

IRM-37xxT SERIES The Notice of Application: Transmission of remote control signal consist of four parts: Encode Part, IR Transmitter Source, IRM device, Decode Part 1. When IRM-37xxT SERIES code select frequency, it need to well understand the center system of encode part. 2. Strong or weak light of IR Transmitter can affect distance of transmission. 3. When using IRM-37xxT SERIES device, it requires the composition of code pattern to reach the demand as follows: Minimum tburst ( number of pulses per burst) Minimum tburst_gap ( number of pulses between two burst) Minimum tpause 10 pulses 14 pulses 25 msec 4. It needs to ensure the translation range of decode part if it is applied to the pulse-width range. If the above items hardly assure of its application, it’ll cause NG(no good) message from the edge of signal.
