Issue No: DMO-0000371 Rev 3 www.everlight.com DATASHEET Infrared Remote-control receiver module V三 RACH IRM-36XXT series The Notice of Application: Transmission of remote control signal consist of four parts: Encode Part, IR Transmitter Source, IRM device, Decode 1. When IRM-36XXT 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-36xXT device, it requires the composition of code pattern to reach the demand as follows creburst urst gap Command No. 1 Command h。.2 Minimum burst Minimum tourst_gap number of pulses number of pulses per burst) Minimum pause between two burst) 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'l cause ng(no good message from the edge of signal Copyright o 2010, Everlight All Rights Reserved.
