BNC-2110

Desktop and DIN Rail-Mountable BNC Adapter for Multifunction DAQ Devices

This installation guide describes how to install and configure your BNC-2110 accessory with an E Series, S Series, or NI 671X/673X waveform generation Multifunction DAQ device.

The BNC-2110 is a desktop and DIN rail-mountable BNC adapter you can connect to data acquisition (DAQ) devices. The BNC-2110 includes 15 BNC connectors, a terminal block with 30 pins for signal connections, and a 68-pin I/O connector that connects to the E Series, S Series, and waveform generation Multifunction DAQ devices. The BNC-2110 is ideal for simplifying connections between your measurement apparatus and your DAQ device in laboratory, test, and production environments.

What You Need to Get Started

To set up and use your BNC-2110 accessory, you need the following:

❑ BNC-2110 BNC Adapter

❑ BNC-2110 Installation Guide

❑ Multifunction DAQ device and the appropriate cable

❑ Small flathead screwdriver (supplied)

For detailed specifications for the BNC-2110, refer to the Specifications section.

Installing Your BNC-2110

To connect your BNC-2110 to your DAQ device, refer to Figure 1 as you complete the following steps. Consult your computer user manual or technical reference manual for specific instructions and warnings.

Note If you have not already installed your DAQ device, refer to the DAQ Quick Start

Guide for instructions.

1. Place the BNC-2110 near the host computer or use the optional DIN rail-mounting kit, which you can order from National Instruments. For more information about the DIN rail-mounting kit, refer to the National Instruments Web site at

ni.com or call the office nearest you.

2. With the DAQ device powered off, connect the BNC-2110 to your DAQ device using the appropriate cable. Refer to Table 1 to make sure that you have the proper cable for the DAQ device that you are using.

3. Make sure the floating source (FS)/ground-referenced source (GS) switches under BNC connectors AI <0..7> are set correctly for your application. Refer to the Connecting Analog Inputs (E Series and

S Series Devices Only) section for more information.

4. Connect the field signals to the BNC connectors and/or digital spring terminal plugs. Refer to the Configuring the BNC-2110 section for more information.

5. Refer to the DAQ Quick Start Guide to launch Measurement & Automation Explorer (MAX), confirm that your DAQ device is recognized, and configure your device settings. National Instruments recommends that you use your DAQ device in differential mode when using the BNC-2110.

6. Test specific device functionality, such as the ability to send and receive data. Refer to the DAQ Quick Start Guide for more detailed information about running test panels in MAX.

When you have finished using the BNC-2110, power off any external signals connected to the BNC-2110 before you power off your computer.

Caution The BNC-2110 is not designed for input voltages greater than 42 V, even if a

user-installed voltage divider reduces the voltage to within the input range of the DAQ device. Input voltages greater than 42 V can damage the BNC-2110, any device connected to it, and the host computer. Overvoltage also can cause an electric shock hazard for the operator. National Instruments is not liable for damage or injury resulting from misuse.

Connecting the Cables

Caution Do not connect the BNC-2110 to any device other than National Instruments

E Series, S Series, or waveform generation Multifunction DAQ devices. Doing so can damage the BNC-2110, the DAQ device, or the host computer. National Instruments is not liable for damage resulting from these connections.

The BNC-2110 has one 68-pin connector on the rear panel to connect to your DAQ device. Refer to Table 1 to make this connection.
