64 1-Wire Terminal Block for the NI PXI-2533

This document describes how to install and connect signals to the 
National Instruments TB-2633 terminal block. Refer to the 

NI Switches 

Getting Started Guide

 to determine when to install the NI TB-2633.

Introduction 

The NI TB-2633 terminal block installs in front of the NI PXI-2533 switch 
module and has screw terminals that provide access to the rows and 
columns of the matrix. 

1. Unpack the Terminal Block

The terminal block is shipped in an antistatic package to prevent 
electrostatic discharge (ESD) that can damage several components on the 
terminal block. To avoid such damage when you handle the terminal block, 
take the following precautions:

Caution

Never 

touch the exposed pins of connectors. 

Ground yourself using a grounding strap or by touching a grounded 
object.

Touch the antistatic package to a metal part of the chassis before you 
remove the terminal block from the package.

Remove the terminal block from the package and inspect the terminal block 
for loose components or any sign of damage. Notify NI if the terminal 
block appears damaged in any way. Do 

not

 install a damaged terminal 

block on a switch module.

Store the terminal block in the antistatic package when not in use.
