Network Considerations

Newt Networking Software

Ethernet Components and Wiring The NetDAQ instruments and host computer should be connected to the network as shown in Chapter 2 of this manual.

Instrument Preparation Each NetDAQ instrument should be connected to an ac outlet or dc source with a proper ground. The instrument’s line frequency and network parameters should be set properly (see “Instrument Preparation” in Chapter 2 of this manual).

General Network Parameters Before you begin software installation, obtain the parameters needed to complete the items listed below. These parameters are available from your network administrator, network software vendor, or Ethernet adapter documentation. The default gateway parameters are only needed if your network contains router or gateway devices. The Ethernet adapter parameters are needed only if this hardware is not in the list of devices supported by the Newt installation program. The socket port number is needed only if the default socket port number (4369) is currently in use on your network.

If your host computer is already running network software in the Windows 3.1 or

3.11environment using a separate adapter and isolated network wiring, make sure that the two Ethernet adapters do not interfere with each other. Consult the documentation that came with your Ethernet adapter and see and see “Running Two Network Cards in a PC” in this appendix for information on installing two network adapters on one host computer.

Newt TCP/IP vs. Novell NetWare

If you have the Novell TCP/IP package (LAN Workplace for DOS/Windows) with WINSOCK already installed on your PC, you do not need to install the Newt package. You do, however, need to get the winsock.dll associated with the LAN Workplace product from Novell. This is available by down-load from CompuServe or from the Novell BBS.

If you don’t have the Novell TCP/IP package, use the Newt package with the basic NetWare client software on your PC. First, boot your PC with your Novell NetWare Client software active. Make sure that the version of NetWare you have uses an ODI driver.

Next, use the basic Newt installation procedure in this appendix. Newt Setup will detect the presence of the Novell NetWare software and automatically modify the NetWare net.cfg file. If Newt Setup cannot find the active net.cfg file, it will prompt you for its location.

Novell NetWare uses an ODI driver, loaded during your Novell client code setup. The Newt TCP/IP stack will be loaded to operate over this driver.

On completion of Newt installation, you will see that the net.cfg file in the Novell NetWare directory has had something like the following lines added (example for the Intel EtherExpress 16C adapter).

Fluke 2640A, 2645A user manual Newt TCP/IP vs. Novell NetWare

2645A, 2640A specifications

The Fluke 2640A and 2645A are advanced bench multimeters that represent a significant leap in measurement technology, designed primarily for electrical engineers and technicians who require precision and reliability in their readings. These multimeters are built to cater to complex applications in manufacturing, research, and development.

One of the standout features of the Fluke 2640A and 2645A is their high accuracy. With specifications that can reach up to 0.0035% DC Voltage accuracy, users can trust that their measurements will be consistent and precise. This is especially critical in fields like automated test equipment (ATE) where exact measurements can be crucial for product quality and safety.

Both models incorporate a large, easy-to-read display, making it convenient for users to view measurement results clearly from a distance. They also feature a wide measurement range, capable of handling a variety of tasks, from basic voltage and current measurements to more complex tasks such as resistance and temperature measurements with appropriate sensors.

The multimeters also stand out with their advanced data logging capabilities. The Fluke 2645A, for instance, can store up to 10,000 readings, allowing for extensive data collection and analysis without the need for constant monitoring. This is beneficial for long-term studies or processes that require continual oversight.

Connectivity is another key characteristic. Both the 2640A and 2645A support USB and RS-232 interfaces, which enable easy integration with computers and other devices for seamless data transfer. This feature is important for engineers who rely on software for data analysis and visualization.

Another notable technology included in these models is the Fluke Connect app compatibility, which allows users to remotely monitor measurements from their smartphones or tablets. This capability provides added flexibility, enabling technicians to work hands-free while still keeping an eye on process measurements.

Additionally, the Fluke 2645A comes with a graphical display option, allowing users to visualize measurement trends over time. This graphical representation can be invaluable for diagnosing issues or observing patterns in data.

In conclusion, the Fluke 2640A and 2645A multimeters offer exceptional performance with their high accuracy, extensive data logging, connectivity options, and advanced visualization capabilities. These features make them indispensable tools for professionals in a variety of fields, ensuring that they can achieve reliable results in their measurement endeavors.
