INSTALLATION GUIDE

BNC-2142 DESKTOP AND DIN RAIL-MOUNTABLE

BNC ADAPTER

This installation guide describes how to install and configure your

BNC-2142 accessory.

Introduction

The BNC-2142 is a desktop and DIN rail-mountable BNC adapter you

can connect directly to dynamic signal acquisition (DSA) devices. It

includes six BNC connectors for signal connections, and a 68-pin

I/O connector for connection to the PCI-445xand NI 455xDSA devices.

The BNC-2142 is ideal for simplifying connections between your

measurement apparatus and your DSA device in laboratory, test, and

production environments.

What You Need to Get Started

To set up and use your BNC-2142 accessory, you will need the following:

❑BNC-2142 BNC Adapter

❑BNC-2142 Desktop and DIN Rail-Mountable BNC Adapter

Installation Guide

❑PCI-445x or NI 455xdevice

❑SHC68-C68-A1 analog cable

Detailed specifications for the BNC-2142 are in the Specifications section

later in this guide.

Connecting Signals to Your BNC-2142

This section describes how to connect field signals to your BNC-2142

accessory.

Table 1 describes the BNC connectors available on the front panel of your

BNC-2142.

Note All BNC connectors on the BNC-2142 are single-ended only. The outer shells of the

BNC connectors are in direct contact with the metal enclosure of the BNC-2142, which is

grounded via the SHC68-C68 analog cable shield to the chassis ground of your computer.

Caution Connecting ground-referenced sources to the analog inputs or ground-referenced

loads to the analog outputs may cause ground noise to be picked up from other electrical

equipment also referenced to the source or load ground. Additionally, if the source or load

ground is at a different electrical potential than the ground of the BNC-2142 and DSA

device, ground-loops may occur that can result in incorrect readings, and may damage the

BNC-2142, the DSA device, or the host computer. National Instruments is not liable for

damage resulting from these connections.

To avoid encountering these conditions, electrically isolate orfloat the source or load from

its reference ground to create single-ended connection with a single ground reference on

the BNC-2142.

Connecting Analog Inputs

You can use the BNC-2142 to measure floating analog input signals. The

BNC-2142 connects to the analog input channels on the PCI-445xand

NI 455xDSA devices via the ACH<0..3> BNC connectors.

Connecting Analog Outputs

The BNC-2142 connects to the analog output channels on the PCI-445x

and NI 455xDSA devices via the DAC0OUT and DAC1OUT BNC

connectors.

Cabling

The BNC-2142 has one 68-position 0.8 mm VHDCI connector on the rear

panel to connect to your DSA device.

Caution Do not connect the BNC-2142 to any device other than the National Instruments

PCI-445xand NI 455xDSA devices. Doing so can damage the BNC-2142, the DSA

device, or host computer. National Instruments is not liable for damages resulting from

these connections.

Installing Your BNC-2142

Perform the following steps to connect your BNC-2142 to your DSA

device. Consult your computer user manual or technical reference manual

for specific instructions and warnings.

Note You can either place the BNC-2142 on a workbench near the host computer or use

the available DIN rail-mount kit.

1. Connect the BNC-2142 to your DSA device.

2. Connect the field signals to the BNC connectors. Refer to the

Connecting Signals to Your BNC-2142 section earlier in this guide for

more information.

When you have finished using your BNC-2142, turn off any powered

external signals connected to your BNC-2142 before you turn off your

computer.

Figure 1. Connecting the BNC-2142 to Your DSA Device

Warning The BNC-2142 is not designed for input voltages greater than ±42.4 V, even if a

user-installed voltage divider reduces the voltage to within the input range of the DSA

device. Input voltages greater than ±42.4 V can damage the BNC-2142, any device

connected to it, and the host computer. Overvoltage can also cause an electric shock hazard

for the operator. National Instruments is notliable for damage or injury resulting from such

misuse.
