I am working on a series of CANOpen cable adapters.  For example, here is a model of a DB9 to dual RJ45  adapter:

CANOpen DB9/dual RJ45 adapter

I made sure it will work well with AMC DX15C08 Digiflex drives to convert the DX15C’s DB9M to two RJ45s.  The Phoenix header (in green) is for supplying power to the DX15C’s isolators.  Since I will probably make some more changes (for one, I don’t think there is room to screw the adapter’s DB9F to a DB9M), I am not posting the design files yet.

I have trac page up on connecting CANOpen devices with DB9M connectors to a RJ45 network.

I have a page up on my trac site about connecting CANOpen devices with RJ45 connectors, including RJ45 terminators and breakouts.
