I have been
tracking your progress on the EC2. One thing about using shielded
cables. Both ends need to be grounded and do not use the shield as a
conductor for any function. Data running in adjacent cables can be
corrupted by currents in cables next to
them. If the shields are not grounded at both ends you have created an
antenna. Good luck.
Hi
Joe,
I think what
you just recommended goes against standard practice (as I understand
it). You want your ground for a device to be a dedicated ground, but when
you start connecting shields between devices, you give each device multiple
little grounds as well. This actually sets up the potential for
"ground loops", where you are actually allowing current to
flow through the shields between devices.
I would only
ground one end, and it would be the end that has the main component, with the
best ground (EC-2 box in this case).
Cheers,
