NI 9503 C Series Stepper Drive Modules and SoftMotion Module 

Step 3: Connect the NI 9503 to the NI PS-16 
Power Supply

Tip

Refer to the 

NI PS-16 Power Supply User Manual and Specifications 

for more 

information about connecting and using the NI PS-16 power supply.

Complete the following steps to connect the NI 9503 module to the NI PS-16 power supply.

Tip

Refer to the 

NI 9503 Operating Instructions and Specifications

 for more 

information about module power supply requirements.

1.

Connect the NI 9503 Vsup (pin 8) to one of the two (+) terminals on the NI PS-16. 

2.

Connect the NI 9503 COM (pin 7) to one of the two (-) terminals on the NI PS-16.

3.

Connect the power supply to AC power.

Step 4: Connect the System to AC Power

Complete the following steps to power on the system.
1.

Connect the controller power supply (such as the NI PS-15) to AC power.

Step 5: Install Software on and Configure the 
NI RT Controller

This step covers installing and configuring the software for the NI 9503 stepper drive module. 
It assumes that all required software from the 

What You Need to Get Started

 section is installed 

on the host machine.

Complete the following steps to configure the controller and install software on it.

Note

The NI Measurement & Automation Explorer (MAX) user interface may not 

match these steps exactly depending on which version of MAX you are using. 

1.

Launch Measurement & Automation Explorer (MAX) on the development computer by 
clicking the MAX icon on the desktop, or by selecting 

Start»All Programs»

National Instruments»NI MAX

.

2.

Select the controller under 

Remote Systems

 in the 

Configuration

 pane. If you do not see 

the controller, you may need to disable the firewall on the development computer.

3.

Verify that the 

Serial Number

 in the 

Identification

 section matches the serial number on 

the device.

4.

Expand the controller item in the tree, right-click 

Software

, and select 

Add/Remove 

Software

.

5.

Highlight your device.
