All devices on an Ethernet network are assigned a unique physical address—the Ethernet address—so they can communicate with each other.
National Instruments GPIB-ENET/1000 GPIB Instrument Control Device
Turn on the front-panel power switch. This is especially important for large systems featuring many instruments. You may need to run software configuration and verification utilities at this time. The best way to achieve this is by using instrument drivers. In addition to manually configuring the network parameters, you can use the Ethernet Device Configuration utility for any of the following purposes:.
It is important to choose an alias that you can immediately identify with the intended instrument. You have just confirmed communication with your instrument.

When VISAIC initially runs, it automatically finds all of the available resources in the system and lists the instrument descriptors for each resource under the appropriate resource type.
The unit is now ready to operate. The basic functions and concepts described above may seem simple; however, they can be invaluable in troubleshooting and getting your GPIB system up and running.
If you are setting up your own network, you probably do not have a gateway or DNS server, so you should set these values to 0. To communicate with your instrument at Address 4, follow these instructions:.

This verification process automatically occurs when you either run the utility or refresh the list of devices. The current hostname is displayed. Alternatively, system power may be disrupted for a variety of reasons or the actual instrument may begin to malfunction. Using your computer, you can take advantage of this powerful development and debugging tool to interactively communicate read, write, serial poll, and so on with your GPIB instruments.
Install Instrument Drivers Next. If there is a problem, you no longer see your device. Exit when you are finished using the Ethernet Device Configuration utility. Connect the other end of the Ethernet cable to your Ethernet network. Then select your GPIB controller.
Refresh the list of devices, after the device reboots, to verify that the hostname is now valid.

The utility displays four options for resolving the verification error. Connect the other end to your GPIB instrument. Also have the network administrator assign the proper subnet mask, gateway, and DNS server addresses. If your network uses DHCP, the network configuration is performed automatically at startup. If your network uses DHCP, the network configuration is performed automatically at startup, and you do not need to run this utility unless you want to change the hostname.
Now from the viRead tab, select a count ofthe length of your expected response, and then click Execute to return an identification string. ID querying is discussed in the next section. If your subnet mask is Once you have determined the GPIB address of your instruments, it is easy to establish communications to verify that you can send and receive data to and from the instrument. If you are assembling your own small Ethernet network, you can choose your own IP addresses.
