We collected this question from a customer: Can D2 be Toggle while D3 stays Momentary?
No. RX480E-4 does not provide a separate mode setting for each output pin. You select one working mode for the receiver, and some modes mix output behaviors.
The manual includes Two Toggle + Two Momentary channels. That is one complete mode, not a setting you can change pin by pin.
If that behavior fits your project, use it. If you need a different mode for every pin, RX480E-4 cannot do that.
Do you need one output to stay on only while its button is held, while another toggles on and off?
See the complete mode list in the RX480E-4 manual.
