Tim still has not told anyone what kind of cable he is using, what
kind of connectors and what kind of board. He talks about what happened and
it sounds to me, an older RF Electrical Engineer like a transmission line
problem. Jonathan not withstanding, is a great programer but may not know
much about transmission lines.

In anycase no-one has offered Tim any help that I have seen except Mike who
said if your using this do that...

So Tim why not tell us what your using? I have no experiance with
100 MHz data systems but I have had experiance with ethernet both coax and
twisted pair transmission lines.
