Well, after more experimentation, it doesn't seem to be a problem with cable length at all. It turned out that the 6 foot cable I was using was just plain bad. We had never really thought to suspect the cable itself, since it was sent to us by a vendor (who shall, for the moment, remain nameless) as a "sample"! So, that little problem appears to be solved. I would still like to see any comments people might have about the DESTA in general, though. --Pat.
