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.

P2 - Analog input 2

The slave address and the baud rate are defined via analog input 2. You can find further details in chapter Setting slave address and baud rate.

To use the factory settings, set the potentiometer to 0 (turn counterclockwise as far as it will go). The factory settings are:


Configuration	Object	Factory settings
Slave address	2028_h	5
Baud rate	202A_h	19200
Parity	202D_h	0x04 (Even)

The number of data bits is always "8" here. The number of stop bits is dependent on the parity setting:

No parity: 2 stop bits
"Even" or "Odd" parity: 1 stop bit
