Hi

I use quite a few of  mss100 devices connected to my serial devices...these
then connect to my lan network......

I also use a serial device from B+B Electronics which i have connected to
my
spare Homevision unit..This currently controls my RGBLED Garden lighting
and
my Vegie Garden irrigation system...
