Hi
I assume you want to setup "BandData".
the wire to setup needs some resitors as pull-up and software configuration into the BandManager.
Some info here :
blog.pauls.li/?p=429 - this is for 2K-FA, but It is probably same on 1K3
It exists also some providers (it is about €€...)
Note : it is better to consider to use COMport (assitance by CAT), but BandData doesnot need to setup PC (Serial port, RadioSync....)
P@t
