BIS Key assistance help please

In the USA thread I've been given BISS keys that look a bit strange.
How would I format it to work in oscam-emu r11442?
And would any other file edits be needed? Powervu is working very very well.

I'm not quite sure how to jumble the text around to give it a try.
First attempt at BISS.

Key is for 127W, tp 4070 H, SR 3257-3/4, DVB-S2.
