This document explains how to install, configure, and set up the NI PXIe-4302 and
NI PXIe-4303 (NI PXIe-4302/4303) simultaneous filtered modules with the TB-4302 and
TB-4302C terminal blocks. Driver support for the NI PXIe-4302/4303 was first available in
NI-DAQmx 15.1. For the list of devices supported by a specific release, refer to the NI-DAQmx
Readme, available on the version-specific download page or installation media.
Note The keying of these terminal blocks prevents them from connecting to other
modules that could be damaged by the voltage present on the terminal block.
However, you should only use these terminal blocks with their supported modules.

Installation
Install the Software
Note You must be an administrator to install NI software and devices on your
computer.
Ensure that the following software is installed before installing the NI PXIe-4302/4303 and
TB-4302/4302C hardware:
1. Your application software, such as LabVIEW, LabWindows
2. NI-DAQmx—NI PXIe-4302/4303 modules were first supported in NI-DAQmx 15.1.
Note For detailed NI software version support, refer to the NI-DAQmx Readme.
Back up any applications before upgrading software or modifying the application.

Unpack and Install the Module
Remove the packaging and inspect the module. Contact NI if the module is damaged. Do not
install a damaged module.
Caution The module is static sensitive. Always properly ground yourself and the
equipment when handling or connecting to the module.
Complete the following steps to install the NI PXIe-4302/4303 module while referring to
Figures 1 and 2:
Note To maintain forced air cooling in the PXIe system, refer to the Maintain
Forced-Air Cooling Note to Users.
1. Plug in your chassis before installing the NI PXIe-4302/4303. The power cord grounds the
chassis and protects it from electrical damage while you install the module.
2. Make sure the chassis is powered off.
Caution To protect yourself, the chassis, and the NI PXIe-4302/4303 from
electrical hazards, leave the chassis powered off until you finish installing the
NI PXIe-4302/4303 module.
3. Touch a metal part on the chassis to discharge any accumulated static electricity.
4. Identify a supported PXI Express slot in the chassis. NI PXIe-4302/4303 modules can be
placed only in PXI Express Peripheral slots, PXI Express Hybrid Peripheral slots, and PXI
Express System Timing slots. Refer to the chassis documentation for details.

4 PXI Express System Timing Slot
5. Remove the filler panel, and touch any metal part of the chassis to discharge static
electricity.
6. Place the module edges into the module guides at the top and bottom of the slot.
Caution When installing the module, make sure both edges are positioned inside
the guides and that the module components do not come into contact with adjacent
modules.

7. Slide the module along the guides until it reaches the rear connector then seat the module
by pushing the front panel until it is flush with the front panel of the chassis.
8. Secure the module to the chassis using the front-panel captive screws, shown in Figure 2.
Tighten the screws to 0.31 N · m (2.7 lb · in.).

Connect the Signals
Caution For EMC compliance, operate this product with shielded cables and
accessories.
To connect signals to the terminal block, refer to Figures 3 and, 4 or 5 while completing the
following steps:
Note You can find the pinout names and locations in Measurement & Automation
Explorer (MAX) at any time by right-clicking the device name under Devices and
Interfaces and selecting Device Pinouts.
1. Loosen the captive top cover screws and remove the top cover.
2. Loosen the strain-relief screws and remove the strain-relief bar.
3. Prepare the shielded signal wire by stripping the insulation no more than 7 mm (0.28 in.).

5. Insert the stripped end of the shielded signal wires fully into the appropriate terminal. Refer
to the label next to each screw terminal to determine the function of the terminal. The
NI PXIe-4302/4303 User Manual provides more detailed wiring information. Make sure no
exposed wire extends past the screw terminal. Exposed wire increases the risk of a short
circuit that can cause circuit failure.
