IRM-37xx SERIES
The Notice of Application: (IRM-37xx SERIES)
Transmission remote control signal consist of four parts: Encode Part, IR Transmitter Source, IRM
device, Decode Part
1. When IRM-37xx 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. Minimum Burst Length T
burst
(number of pulses per burst) : 6 or 10 cycles
4. It needs to ensure the translation range of decode part if it is applied to the pulse-width range.
5. IRM-37xx SERIES can be applied to the high data codes, but against disturbance slightly
weak.
If the above items hardly assure of its application, it’ll cause NG(no good) message from the edge of
signal.
