After entering the required network information, I configured a remote instrument over the company LAN.įigure 3. Windows’ winipcfg.exe program shows you a PC’s network settings.įigure 2. If your office PC isn’t on the same hub as your test equipment, your network administrator can connect a PC to the network drop where you want to connect your instrument to find that hub’s IP address.įigure 1.
(In many companies, all the PCs in a department may connect to the same network hub, but check with your network administrator.) Because the unused office and my office were connected to the same network hub, I could use my PC to find the hub’s IP address. I first needed to find the IP address of the network hub that served the empty office. I wanted to use the WebDAQ box in a spare T&MW office, and doing so required me to obtain an unused IP address. Most LANs use Internet protocol (IP), so my test equipment needed an IP address. With help from Bob Pollard, support engineer at Cahners Business Information ( T&MW ’s parent company), and from the folks at CEC, I was able to connect the WebDAQ to the network and begin operating it in about 30 minutes.Įvery computer or instrument connected to a network needs an address. So, I solicited help from our information technology department. Then, I would have had to write my own application software to “serve” information from the DMM to the network.Īt T&MW, we know instruments and measurements, but computer networks fall outside our expertise. I could have used a traditional instrument, such as a DMM, but that would have involved configuring the instrument using an IEEE 488 port on a spare PC and setting up the PC as a Web server. I chose the WebDAQ because it has a built-in Web server that creates and sends HTML documents over a network. (CEC, Billerica, MA, to the company LAN at Test & Measurement World. To learn some of the steps involved, I decided to connect a WebDAQ/100 from Capital Equipment Corp. The method for connecting a piece of equipment to a LAN depends both on the network configuration and on the instrument itself. Many Web-enabled test applications simply require instrument access from within a LAN-behind a firewall. Learn to control your instruments without a Web server connect equipment to the Internet for public use.connect equipment to the company LAN with private, remote access from outside the firewall or.connect the test equipment to your company LAN for use behind the company firewall.Your choice will depend on the type of access you need: There are three ways to provide access to a Web-enabled instrument or test system. You can use these “Web-enabled” test products on a LAN or on the Internet without needing to write software and without needing a PC to host the Web server. Some instrument makers have gone a step further by embedding Web servers into their instruments (see “ Manufacturers of Web-Enabled Test Products,”).
