Figure 1.  

Block Diagram

Getting Started

You will need the following items to get started with your NI ISM-7413:

24 VDC to 70 VDC power supply. NI PS-12 (NI part number 748906-01) or NI PS-13 

(NI part number 748907-01) recommended.

Tool for inserting wires into the connector

A PC running Microsoft Windows 8.1/8/7/Vista/XP, with an available Ethernet port

A CAT5 Ethernet cable (not included)

NI Stepper Configuration Utility, available from 

ni.com/downloads

Refer to 

Choosing a Power Supply
