UMI-7764 and NI ISM-74xx Configuration and
Installation
This section covers the hardware setup for the NI UMI-7764 and NI ISM-74xx integrated
steppers.
Step 1: Connect and Configure the NI UMI-7764
Complete the following steps to connect and configure your UMI-7764.
Tip For more information about connecting external power, encoders, and other
motion I/O signals, refer to the
Universal Motion Interface (UMI)-7764 User Guide
and Specifications
.
1. Connect the SH68-C68-S 68-pin shielded cable between the Motion I/O connector on the
NI 73xx motion controller and the Motion I/O connector on the UMI-7764.
2. Configure the UMI-7764 DIP switches. You must set the DIP switches to the following
settings to match the polarity configuration for the integrated steppers:
• Inhibit Input (S2)—Active Low
• Inhibit Output (S1)—Active Low
The UMI-7764 DIP switch configuration is shown in Figure 12.

3. Connect an ex5 V power supply to the UMI-7764 Power Input Terminal Block. This
connection is required to power the encoder circuitry that converts differential encoder
signals to single-ended signals for the motion controller, as well as to power the UMI-7764
Inhibit Output signals.
