Good evening everyone!
The following is a bit of a headscratcher for me:
I intend to use the serial data extracted from the GPS- header for hook- up the downconverter to a separate uController & LCD, which shall display the current status of the V3d, next to other parameters of my station.
After connecting a serial converter to pin 4 of the GPS- interface and firing up the teminal, I expected to see data according Kurt`s description here: https://www.dj0abr.de/german/t…msat_down_v3_diagnose.htm
However, although I see various diagnostic messages from the converter, the format is way different to the OLD_XX_YY_text- format that I was looking for.
Here is an excerpt of what Putty shows:

Could anybody advise me of what I'm doing wrong?
