Archived: Connecting a GPIB-ENET/100 Directly to a Windows 2000/XP Machine

Hardware: GPIB>>External Controllers/Convertors>>GPIB-ENET/100

I have a GPIB-ENET/100 and I would like to connect it directly to the Ethernet port on my computer. I either get an error saying GPIB interface has been incorrectly configured or I cannot see the device in the NI Ethernet Device Configuration utility. What could be causing these issues?

There are a couple of issues that could be causing these problems. The first potential issue is that the computer is not hooked up to a network so it does not have an IP address. In order to configure a GPIB-ENET/100 box connected directly to your computer, you must first assign your computer a static IP address. Do this by following these steps*:

  1. Open Control Panel
  2. Select Network and Sharing Center
  3. Double-click on Local Area Connection to open the Local Area Connection Status window.
  4. Click Properties to view the Local Area Connection Properties window.
  5. Select Internet Protocol  Version (TCP/IP) and click Properties to open the Internet Protocol Version (TCP/IP) Properties window.
  6. Select the option Use the following IP address: and then enter an appropriate IP address (choose numbers between 0 and 255 for each section). If there is already an IP address given then you can leave it there.
  7. Hit to automatically fill in a Subnet Mask or enter it manually. One possibility is to make the first number 255 and all others 0. If there is already a Subnet Mask given then you do not need to change it.
  8. Verify that you have set the IP address correctly by going to Start, Run and typing cmd to open a command prompt. Then type ipconfig to view your IP settings.

*Note this is for for Windows XP only. Older Windows operating systems will be similar:

The other potential cause is the lack of a crossover cable between the computer and the GPIB-ENET/100. When directly connecting your GPIB-ENET/100 box to your computer you must use a crossover Ethernet cable. You can follow the link below for information on crossover cables.

Once you know that your computer has an IP address and you are using a crossover cable, follow the installation and configuration procedures detailed in the Product Manual: Getting Started with Your GPIB-ENET/100 and NI-488.2 for Windows 2000/NT. Also, see the related KnowledgeBases linked below for more information about troubleshooting your ENET/100 device.
