I bought the AXE027 Cable and this one seems not working.
I get some pages of mixed chars but I cannot read something.
I'm not able to break the output and go to console.
1. B series doesn`t need cable with built in ttl converter
2. miched chars can be because of wrong connection settings
3. you can`t break all and get to console, because your:
a) console is locked
b) firmware is restricted and here is not possible to unlock console, need to downgrade firmware first
c) tv is ci+, no possible to send ctrl +c , shell input is limited
d) all other reasons, first of all - non working cable, bad pinout and so on.
You gave poor info about your television hardware. Btw, i think for B series exlink here is a lot of information, no need to invent the wheel. Just check wiki.
