Note

National Instruments recommends using insulated wire ferrules to prevent 

shorting and add strain relief.

Step 6: Configure the P7000 Drive with the Serial Port 
(Optional)

Note

This step is required only if you are using the P7000 Tools configuration 

software and configuring the drive with the RS-232 port. If you are using an NI 
stepper motor, you can configure the drive with the DIP switches only and proceed 
to 

Step 3: Install Software on and Configure the NI RT Controller

 in the 

Software 

Configuration and Installation

 section to configure the RT target.

1.

Connect the RS-232 serial communication cable between the drive and an available COM 
port on the computer.
You must set the COM port to the following settings:
•

Baud Rate:

19,200

•

Data  Bits:

8

•

Parity:

Even

•

Stop Bits:

1

•

Flow Control:

None
