1. Insert the NI-Motion CD into the CD-ROM drive to display the NI-Motion installation

screen, or download the latest version from ni.com/downloads.

2. If you have autorun enabled, autorun.exe runs automatically. Otherwise, double-click

autorun.exe.

3. Follow the onscreen instructions.

Note You must update the firmware on your NI motion controller(s) before you can

use them with the corresponding version of NI-Motion. Refer to Step 1: Update

Firmware on the Motion Controller in the Software Installation and Configuration

section for detailed instructions.

Step 2: Install the NI 73xx Motion Controller

The following sections explain how to install PXI and PCI motion controllers.

PXI Controllers

1. Power off and unplug the chassis.

Caution To protect yourself and the computer from electrical hazards, the

computer must remain unplugged until the installation is complete.

2. Choose an unused peripheral slot and remove the filler panel.

3. Touch a metal part on the chassis to discharge any static electricity that might be on your

clothes or body. Static electricity can damage the controller.

4. Insert the PXI controller into the chosen slot. Use the injector/ejector handle to fully secure

the device into place.

5. Attach the front panel of the PXI controller to the front panel mounting rails of the chassis

with the slot screws on the chassis.

Caution Always power on the computer containing the motion controller and

initialize the controller before you power on the rest of the motion system. Power off

the motion system in the reverse order.

6. Plug in and power on the chassis.

PCI Controllers

1. Power off and unplug the computer.

Caution To protect yourself and the computer from electrical hazards, the

computer must remain unplugged until the installation is complete.

2. Open the computer case to expose access to the PCI expansion slots.

3. Touch a metal part on the chassis to discharge any static electricity that might be on your

clothes or body. Static electricity can damage the controller.

Getting Started with NI SMD-7610 and NI 73xx |© National Instruments |5

4. Choose an unused +3.3 V or +5 V PCI slot, and remove the corresponding expansion slot

cover on the back panel of the computer.

5. Gently rock the controller into the slot. The connection may be tight, but do not force the

controller into place.

Note Check that the bracket of the device aligns with the hole in the back panel rail

of the computer chassis.

6. Secure the mounting bracket of the controller to the back panel rail of the computer.

7. Replace the cover.

Caution Always power on the computer containing the motion controller, and then

initialize the controller before you power on the rest of the motion system. Power off

the motion system in the reverse order.

8. Plug in and power on the computer.

Step 3: Install Software on and Configure the RT PXI

Controller (PXI Motion Controllers Only)

Note This step is only required if you are using a PXI-7330/7340/7350 motion

controller and an RT PXI controller. If you are not using an RT PXI controller, skip

to the Step 4: Connect and Configure the NI UMI-7764 section.

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

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

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

1. Boot the NI PXI embedded controller into the real-time operating system. The PXI

controller automatically boots into LabVIEW RT Safe Mode when no software is installed.

LabVIEW RT Safe Mode loads with the basic real-time operating system and automatically

attempts to connect to the network using DHCP. If DHCP is not available, the controller

connects to the network with a link-local IP address.

Tip You can connect a monitor to the PXI to display startup messages such as the

IP address and MAC address.

2. 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»Measurement & Automation.

3. Expand the Remote Systems branch. MAX lists the PXI controller as the model name of

the controller followed by the MAC address (for example, NI-PXI-8104 00802f108562).

6|ni.com |Getting Started with NI SMD-7610 and NI 73xx

Tip Record the PXI controller MAC address, located on the side of the controller,

for use in identifying the controller. The label also can be removed and placed on the

front of the controller for easier access. If you have connected the PXI controller to a

monitor, the MAC address also appears when the PXI system boots up.

4. Select the System Settings tab and type a descriptive name for the system in the Name

field.

5. (Optional) Complete this step only if the target has an empty IP address (0.0.0.0). Select the

Network Settings tab and select DHCP or Link Local from the Configure IPv4 Address

list to assign an IP address or select Static to specify a static IP address in the IPv4 Address

section.

6. Click Save on the toolbar and let MAX reboot the system.

7. When the new system name appears under Remote Systems, expand the controller item in

the tree, right-click Software, and select Add/Remove Software.

8. Install the LabVIEW Real-Time software and NI-Motion on the RT target. Go to

ni.com/info and enter etspc for the latest information about supported software.

9. Click Next to install the selected software on the controller. Click Help if you need

information about installing recommended software sets.

10. Wait for installation to complete, then click Finish.

11. Expand the Devices and Interfaces item under the PXI system.

12. Right-click the remote motion controller icon and select Map to Local Machine. This

assigns a local board ID to the remote motion controller in the host system.

Mapping the remote controller into the local system allows you to configure the controller

through MAX exactly as you would a controller that is in the host system. You can initialize

the controller, download firmware, and use the interactive and configuration panels exactly

as you would on a controller installed in the host machine. You also can write VIs using the

remote motion controller through the local board ID assigned to it.

This allows you to write and debug your VIs on the host, and then download them to the

remote system when you are ready. All you need to change is the board ID in your VI from

the locally assigned Board ID to the ID assigned by the remote system.

13. Browse to Devices and Interfaces under My System, where there is a shortcut icon next

to a new controller name.

For example, if the motion controller on the remote system is a PXI-7354, and the remote

system has an IP address of 123.45.678.9, then the shortcut device would show a name

like PXI-7354 (X) on 123.45.678.9 (Y).

Xis the board ID assigned to the board by the remote system. Use this board ID for VIs that

are downloaded to the remote system through LabVIEW RT.

Yis the board ID assigned to the remote motion controller by the local system. Use this

board ID for any VIs that run on the host and use the remote motion controller.

14. Close MAX.

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 SMD-7610 stepper drive:

• Inhibit Input (S2)—Active Low

• Inhibit Output (S1)—Active Low

The UMI-7764 DIP switch configuration is shown in Figure 2.

Figure 2. UMI-7764 Inhibit Input and Inhibit Output DIP Switch Settings

3. Connect an external +5 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.

Caution Do not plug in or turn on any power to the system until after all hardware

connections are complete.
