Feedback and Control Cable Assemblies
The Ocarina Evaluation Board features easy-to-use D-sub type connections for all Control and
Feedback cables. Below are instructions and diagrams describing how to assemble those
cables.
Use 24, 26 or 28 AWG twisted-pair shielded cables (24 AWG cable is recommended).
For best results, the shield should have aluminum foil covered by copper braid.
Use only a D-sub connector with a metal housing.
Attach the braid shield tightly to the metal housing of the D-type connector.
On the motor side connections, ground the shield to the motor chassis.
On controller side connections, follow the controller manufacturer’s
recommendations concerning the shield.

Note: All D-sub connectors, used with the Evaluation Board, should be assembled in this way.
Metal Housing
Make sure that the braid shield is in
tight contact with the metal housing
