Connecting the NP5 controller via the Discovery Board

The NP5 Discover Board helps you during tests and during the evaluation of the NP5 controller.

The connectors necessary for the boards are supplied already installed.

Jumper X13 must be set if CANopen (NP5-08) is used; otherwise, you must remove it.
