experiments with SB9600 on the XTL series
You'll need a RIB of some flavor. Either genuine or aftermarket. RIBless cables are probably doable but I'll figure that out later.
RIB DB25 Pin XTL J2 Pin
--------------------------
BUS+ (15/24) BUS+ (2)
BUS- (11/13) BUS- (3)
/BUSY (6) BUSY (9)
This is what I used to connect my RIB to the XTL. Seems to work fine. Not sure if the SB9600 RESET line is necessary. The DSM says it's only used for collision mitigation.
You'll need a python 3 installation and pyserial installed via pip.
The listener.py script will print out any SB9600 or SBEP messages, and decode them if they're recognized. Simply change the COM port in the script and run it. Exit with Ctrl+C
