Re: How close can the wires be ? - Advice needed.

How long have the Rev7's been out? I have 3 320's that I purchased
in Nov of 2002. I took the connectors off, but could not see any
marking to indicate the rev, so I assume that I have an older rev.

I have the encoder wire in a seperate shielded cable that is
grounded at the box end only. I will be running the motor wires in a
seperately shielded cable, but want to run them together in a
plastic conduit to the servos. Do you think I will have any issues
with this?
