If you have a Teensy and Soarer's firmware it should work easily. If you have one of Orihalcon's converter cables, the XT uses a 180 degree DIN while a 122 uses a 240 degree DIN and they are not interchangeable.

Hi, my F122 uses a 180 degree DIN, strangely. However, In another project I tried to make an additional cable in order to convert an old teensy / soarer's by Orihalcon 240° to 180° without success.

In practice: usb cable from pc >teensy 2 with 240° female plug soldered > additional short cable to convert 240° to 180° (male-female), according to pin coupling > keyboard male connector. It doesn't work. Perhaps an impedance problem I have never solved. Who knows why?

Yes, I suggest you to buy with confidence from Orihalcon. His converter cables are very fancy.
