irm-2733a Everlight Electronics Co., Ltd., irm-2733a Datasheet - Page 6

• Manufacturer Part Number: irm-2733a
• Description: Infrared Remote-control Receiver Module
• Manufacturer: Everlight Electronics Co., Ltd.

The Notice of Application:
Transmission o remote control signal consist of four parts: Encode Part, IR Transmitter Source,
IRM device, Decode Part
1. When IRM-27xxA code select frequency, it need to well understand the center system of encode
2. Strong or weak light of IR Transmitter can affect distance of transmission.
3. When using IRM-27xxA device, it requires the composition of code pattern to reach the demand
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.
