Bc2000 (for the BCF2000 & BCR2000)

Hi Kip,
I've 10 bcf2000 connect to 2 midi merger, then I've 80/100mt cable  to
connect their to my digital mixer. I don't want use any type pc/mac
during my work, bad experience in the past. I'd use the pc just for
setting the bcr's.My idea is: i use some adapter to convert
midi-to-lan lan-to-midi, but i've find just kissbox and nothing else.
Some one have other idea? I'm making some schematic about one
standalone midi adapter midi-to-rs485/422   rs485/422-to-midi and even
make the circuit myself but I've not so much time now. 
Thats all 

best regards
Alessandro
