NI PXIe-4340 and TB-4340
4 Ch, 24-bit, 25.6 kS/s Simultaneous AC LVDT Input Module
This document explains how to install, configure, and set up the NI PXIe-4340 LVDT and RVDT
module with the TB-4340 terminal block. Driver support for the PXIe-4340 was first available
in NI-DAQmx 15.5. 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 this terminal block prevents it 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.

Complete the following steps to install the PXIe-4340 module while referring to Figures 1 and 2:
Note To maintain forced air cooling in the PXI Express system, refer to the
Maintain Forced-Air Cooling Note to Users.
1. Plug in your chassis before installing the PXIe-4340. 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 PXIe-4340 from electrical
hazards, leave the chassis powered off until you finish installing the PXIe-4340
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. PXIe-4340 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.
Figure 1. Symbols for PXI Express/PXI Express Hybrid/PXI Slots
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.

Connect the Signals
Caution To ensure the specified EMC performance, operate this product only with
shielded cables and shielded accessories. Use only twisted, shielded pair cables for
channel connections. Refer to the NI PXIe-4340 User Manual for specific guidance
on terminating cable shields.
To connect signals to the terminal block, refer to Figures 3 and 4 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.).
4. Run the shielded signal wires through the strain-relief opening.

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-4340 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.

6. Tighten the terminal screws to a torque of 0.2 to 0.25 N · m (1.77 to 2.21 lb · in.).
Caution Any wires connected to the ground must be sufficiently insulated from
high voltage.
7. Use the ground lugs to attach a shield wire to the ground.
Note Refer to the NI PXIe-4340 User Manual for details about shielding the
signals.
8. Reinstall the strain-relief bar and tighten the strain-relief screws.
9. Use tie wraps to connect the shielded signal wires to the tie-wrap holes for additional strain
relief when necessary.

Install the Terminal Block
Refer to Figure 5 to install the terminal block on the module while completing the following
steps:
1. Move the TB-4340 into position in front of the PXIe-4340 and engage the alignment feature
with the guide on the associated module.
Figure 5. Installing the TB-4340 on the PXIe-4340 Module
2. Attach the TB-4340 to the PXIe-4340 module by pushing the terminal block straight into
the module. A spring mechanism will lock in the bottom of the terminal block.
3. Tighten the mounting screw at the top of the TB-4340 to attach it to the PXIe-4340 module.
Note For safety purposes and to prevent damage to equipment when high voltages
are present, all PXIe-4340 modules and TB-4340 terminal blocks are keyed to
prevent connection between incompatible terminal blocks, modules, and/or cables.

Confirm PXIe-4340 Module Recognition
To confirm module recognition, complete the following steps:
Note Software support for the PXIe-4340 is provided by NI-DAQmx. The Read
Me First: NI-DAQmx and DAQ Device Installation Guide, which you can download
at ni.com/manuals, offers step-by-step NI-DAQmx instructions for installing
software and hardware, configuring channels and tasks, and getting started
developing an application. For detailed NI software version support, refer to the
NI-DAQmx Readme.
1. Launch MAX.
2. Expand Devices and Interfaces, and expand the chassis in which the module is located to
confirm that MAX detects the module and terminal block. The terminal block should
appear beneath its associated module. If your module or terminal block is not listed, press
<F5> to refresh MAX. If the module is still not recognized, go to ni.com/support/
daqmx.
