RX480E-4C: The LED Blinks, but Why Do D0-D3 Show No Output?

Hello!


My remote works and the LED is blinking when remote button is pressed. But no matter which mode I’m in, no power I being emitted through D0-D3?

I keep seeing the same comment: the remote works and the receiver LED blinks, but D0-D3 seem to have no output.

Are you also experiencing the same problem?

D0-D3 are signal outputs, not power rails. The manual gives a maximum output current of 10 mA, so don’t connect a relay coil, lamp, or motor directly.

To check the signal, re-pair at DC 3V-5V, choose a mode, and disconnect the load. Measure D0 to GND before, during, and after a button press.

Which signal result do you get: no change, a change only while pressed, or a change that stays after release?
