I have a Lyra 3 adapter in Amiga 1200, and I decided to try the mode for the Amiga keyboard. I cleaned the surface of the jumper contacts above the .de inscription with isopropyl alcohol and made a jumper by connecting them with a small piece of aluminum foil, secured with insulating tape. Unfortunately, only the caps light is on during the startup of the Amiga keyboard, and the keys do not work. However, the PC keyboard after shorting the jumper behaves the same as before shorting, it has the same key mapping and the shift+pause options work. I repeated the whole procedure 3 times. After clicking F7 on the PC keyboard, the tab changes to LAmiga-pause toggles jumper pin, but I press these combinations and nothing happens, I still have the same key mapping. Should I risk soldering? Did I mix up the jumper? Or is there something wrong with the firmware?
this is the picture of jumper:
