ARP protocol or have static routing tables, you don’t have to use these parameters. In the Proxy ARP protocol, the routing path between any two hosts is automatically established by the routers during the ARP process.

The NetDAQ PC software communicates with the NetDAQ instruments in a totally peer-to-peer manner. Operation of the instruments and software require no server support. As a result, as long as your network can carry and route TCP/IP packets, you should have no interaction between communication with the NetDAQ instruments and other traffic on the network.

The PC software runs in the MS Windows environment and is designed to operate over any winsock.dll that supports version 1.1 of the WINSOCK standard. A 16-bit WINSOCK and TCP/IP software package (Trumpet) is included with the PC software. However, if your PCs already have a winsock.dll and TCP/IP stack loaded, you should use that instead. Especially in Novell environments, you may want to use the “LAN Workplace for DOS & Windows” product from Novell instead of the WINSOCK and stack supplied with the NetDAQ Logger software.

Whichever winsock.dll that you use, make sure that there’s only one file with this name in any directory specified in your PATH. WINSOCK libraries are specifically matched to the underlying TCP/IP software and are not interchangeable between software vendors. If the wrong winsock.dll is found during NetDAQ Logger startup, it will be loaded and the network interface will not operate.

The NetDAQ instruments have both coaxial (10Base2) and unshielded twisted pair (10BaseT) connectors for network connection. Only one of these may be connected to a network at any one time because network activity on the connection is used to automatically select which is to be active.

If you are already using the TCP/IP protocol for client/server activities on your network, you may want to review the socket port assignment for the NetDAQ instruments and PC software. If you already have a service assigned to the socket port that is used as the default in the NetDAQ products, you may have to change the port used by NetDAQ. The list of supported services is usually in the “SERVICES” file in the directory that contains the TCP/IP stack software. Changing the socket port used by NetDAQ is easy to do (see Chapters 2 and 3 of this manual for details).

Again, if you are already using TCP/IP, you must assign IP addresses to the instruments (and PCs of course) in accordance with your established subnet scheme. If you install the NetDAQ Logger software for “general network” operation, you are free to select any IP address for the PC and instruments. With the isolated network operation, you are limited to using the 198.178.246.0 subnet (Class C subnet assigned to the Fluke Corporation) for both the PC and instruments.

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.
