JP1 Remotes

[supertommy]

after about ten years I decided it was time to start playing again with a jp1.x remote control but I remember absolutely nothing.
I found my old rtl2832u usb-serial interface but I have absolutely no idea about the pin - color association.
And I have no idea even the pinout of this remote control, can anyone help me? Thank you

in this image found online (waiting for mine to arrive) you can see the connector at the bottom

edit:

I probably asked the question wrong, I meant to ask how to identify pin1 in the jp1.x connector since there are no printed indications. Looking at the other remote controls I have I noticed (I remembered) that the hole in the jp1 connector has a battery shape and this allows you to identify pin1 and consequently the other pins. Luckily everything went well (years ago I killed a remote control by connecting the evil pin 5)
