Chapter 1 Introduction Unpacking Your RT Series DAQ device is shipped in an antistatic package to prevent electrostatic damage to the device. Electrostatic discharge can damage several components on the device. To avoid such damage in handling the device, take the following precautions: Ground yourself by using a grounding strap or by holding a grounded object. Touch the antistatic package to a metal part of your computer chassis before removing the device from the package. Remove the devi

2 Installation and Configuration This chapter explains how to install and configure your RT Series DAQ hardware. Installing the Hardware You can install the RT Series DAQ device in any available expansion slot in your computer or PXI chassis. To reduce noise, however, leave as much room as possible between the RT Series DAQ device and other devices and hardware. The following are general installation instructions. Refer to your computer user manual or technical reference manual for specific inst

Chapter 2 Installation and Configuration Figure 2-1. Measurement & Automation Explorer Notice that MAX assigns separate device numbers to the PCI/PXI-7030 device and the DAQ daughterboard, as shown in Figure 2-1. The DAQ daughterboard is shown as a separate device under the 7030 processor board. However, the daughterboard has a device number that is different from the 7030 processor board. You need the device numbers of your RT Series DAQ hardware to download and run LabVIEW RT VIs to your RT Se

Chapter 2 Installation and Configuration daughterboard directly, even though the DAQ daughterboard is configured as a separate device. Only LabVIEW RT applications targeted to the RT Series DAQ device can access the DAQ daughterboard. Tip If you want to test whether the DAQ daughterboard is working, run any DAQ example that ships with LabVIEW RT. To save the configuration information, select Tools»NI-DAQ Configuration»Save Configuration As. Then close MAX. RT Series DAQ Device User Manual 2-4 ni
