APPENDIX B. EXAMPLE OF REMOTE CONTROL TRANSMISSION FORMAT

(In the case of NEC transmission format in command one-shot transmission mode)

Caution When using the NEC transmission format, please apply for a custom code at NEC Electronics.

(1) REM output waveform (from <2> on, the output is made only when the key is kept pressed)

REM output

58.5 to 76.5 ms

< 2 >

< 1 >

108 ms

Remark If the key is repeatedly pressed, the power consumption of the infrared light-emitting diode (LED) can

be reduced by sending the reader code and the stop bit from the second time.

(2) Enlarged waveform of <1>
