Search again, I found the digrams last night.
Requires some transistors
Someone said the cable for the R5 works, possibly also the cable for
the Yaesu 120

Anyone got the pin outs for the ERW-4C programming cable for the Alinco
rigs, looks like it fits most, but i do have a DJ-X3/E (not bad for the
price i paid, a little slow for the scan speed but tolerable for my
needs).
Searched for hours and haven't found it posted anywhere, none the less i
just can't force myself to give anyone $40+shipping for a silly cable
that cannot coinsist of more than $3 of parts. Namely a DB9, 3.5mm plug,
serial cable/wire, and maybe some shielding, if i were to purchase it
instead of looking in my junk bins.
