Thanks Sascha, I will order a couple :o)

Erik, I use RS 422 for DMX 512, and am very aware of termination, although some EE's I have worked with seem to think it is not needed (waiting for a major show to "wig out" on them ;o))

I have most of the nat semi and TI apnotes printed out for designs now :o)


Regards,

Kat. (who one day will write a book on RS 485)
