(EDIT: this Picture is only right if the Cable is soldered on the Top side - which nobody does — see 2 posts below this one for the correct picture from the backside)
(PS the PCB is shown from TOP aka Component-Side)
AND its a 1:1 Cable,
Si is only otherwise Labeled > for example:
the DOUT Pin “So” on the Core Module - is labeld “Si” on the Controllsourface
the DIN Pin “Si” on the Core Module - is labeled “So” on the Controllsourface
thats the logic behind most all Modules - for example the SD-Card-PCB has the same OUT<<>>IN Mirroring - but thats all only Labeling, the wiring is 1:1.
>>> wilba had done drawn his Board that Si is Si and So goes to So
So you just have to know how to crimp a Wire 1:1, and you are good.
(PS2: your picture off the cable is so small i cant identify anything there…)
that the “Si” to “So” part is just what I needed. I guess it is time for glasses finally
So if solder this J8/9 “Pfostenbuchse” on the underside of the PCB the direction is reversed meaning the nose looks to the left? (Instead of to the right as in your picture).
