Re: Re: RS485 - XPL on the wire

Hi All,

http://www.hth.com/easytap/default.htm

May be of interest.......

I've alsways thought that RS485 was mainly about the "hardware"
layer.

SNAP,  http://www.hth.com/snap/
which I know many are aware of,  is one
protocol that can sit on RS485, as indeed is DMX512
http://www.dmx512-online.com/physl.html
, if I've got this wrong feel free
to take me into a dark corner and tell me so.

Regards

Stuart
