What is a "shield drain" and how do you know this? It is just off the top of your head, or is there some more authoritative source for this info? (anyway, it sounds like there is nothing to prevent you from tying all grounds together, unless the power comes from a source with a separate ground from what the data ground is tied to, which could give bad ground loops. In that case I would assume that you would tie the shield ground to the power ground. > _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
