INSTALLATION GUIDE

CB-100 I/O CONNECTOR BLOCK

This installation guide describes how to connect the CB-100 I/ O connector

block to your data acquisition (DAQ) board.

Introduction

With the CB-100 I/O connector block, you can easily connect external

signals to the National Instruments DAQ boards. When used with a ribbon

cable, the CB-100 is a low-cost, ribbon-cable alternative to a shielded

connection scheme. The CB-100 I/O connector block is available with an

R1005050 or NB5 ribbon cable.

With an R1005050 ribbon cable, the CB-100 can connect to devices that

use a 100-pin female 50-mil D-type connector. These devices include the

PCI-DIO-96 and PXI-6508 digital I/O boards, the PCI-6025E and

PCI-6071E multifunction I/O boards, and most other 100-pin DAQ boards

from National Instruments.

With an NB5 ribbon cable, the CB-100 can connect to the PC-DIO-96

digital I/O board.

The CB-100 kit consists of a 1.0 m R1005050 or NB5 ribbon cable

assembly and two connector blocks with 50 screw terminals each. The

cable assembly has two 50-pin cables and three connectors. The cables are

joined to a single 100-pin connector on one end and two 50-pin connectors

on the free ends. Each cable connects to 50 pins of the 100-pin connector

and has a label identifying those pins. For connector pinout information,

see your DAQ board user manual. The 50-pin connectors have a centered

tab that you must align with the slot on the mating header on the connector

block.
