But thats if your using 'balanced' transmission like RS422, here its
RS232C which is unbalanced, ie 1-wire for TX and 1-wire for RX.
Thats my 0.02 Euro worth.

I always thought that if you are using CAT-5, and you use one pair for
TX
and a pair for RX, and common the grounds, then you can get a bit of
benefit
>from
as the ground line and the signal line are exposed to (basically) the
same
induced noise along the cable path, hence leaving the original signal
"untouched" (or less touched at any rate)

Remember that CAT5 isn't (normally) shielded!
It's _balanced_, but you need a lot more than a cheapy convertor to take
advantage of that!
