I was trying to get a IR signal from a remote controller.

I hooked the IR receiver to the oscilloscope and I got nothing. Then iI brought the remote controller very close (~1mm far of~1 mm from the receiver) and I started getting a signal, but it was random (with another controller that I have, if I hold one button, it first sendsends the button code and then a constant value; this doesn't happen with the other controller).

I disassembled the controller,controller; this is all the information I got:

  • XWDB-1106
  • LXZK-TX1021-v1.0
  • (cristal oscillator) NDR4208 [I(I think it ends with "i1", I'm not sure]sure)

The receiver I'm using it'sis the VS1838B.

Schematic

Maybe the controllercontroller's frequency it'sis not the same as the receiverreceiver's?

Edit: The remote controller was RF, not IR.
