IRM-36xxT 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-36xxT 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-36xxT SERIES device, it requires the composition of code pattern to reach the
demand as follows:
Minimum t
burst
( number of pulses per burst)
Minimum t
burst_gap
( number of pulses
between two burst)
Minimum t
pause
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.
