Caution: Electrostatic discharge can damage several components on your GPIB board. To avoid this when handling your board, touch the antistatic plastic package to a metal part of your computer chassis before removing the board from the package. Follow these steps to install your interface: 1. Make sure that your computer is powered off.

Keep the computer plugged in so that it remains grounded while you install the GPIB hardware. Remove the top cover (or other access panels) to gain access to the computer expansion slots. Find an unused expansion slot in your computer. You can plug your PCI board into either a 3.3 V or 5 V, 32- or 64-bit PCI slot. You can plug your PCI Express board into a x1, x4, x8, or x16 PCI Express slot. Remove the corresponding slot cover on the back panel of the computer.

Insert the GPIB board into the slot with the GPIB connector sticking out of the opening on the back panel, as shown in Figure 1. It might be a tight fit, but do not force the board into place. Your PCI Express board may be larger than the one shown in the figure. PCI/PCI Express Installation 6.

Screw the mounting bracket of the GPIB board to the back panel rail of the computer. Replace the top cover (or the access panel to the expansion slot). Power on your computer.

The GPIB hardware installation is now complete. GPIB Configuration Use the following video tutorials or the document below to assist you in completing this task: The Measurement & Automation Explorer (MAX) utility comes with the NI-488 driver for your GPIB controller. MAX makes GPIB instrument detection and control easy by providing tools to help you search for connecting instruments, and send and receive communication with your device. Open MAX by clicking on the icon on your desktop or by going to StartProgramsNational InstrumentsMeasurement & Automation. MAX Main Menu To confirm that your GPIB device is connected properly, expand the Devices and Interfaces subdirectory below My System. This tutorial uses a USB-GPIB-HS controller.

If you are using a PCI, serial, or Ethernet controller/converter, the name may be slightly different. Click on Scan for Instruments. Scanning for Instruments in MAX If your GPIB device is SCPI-compliant, the name and address appear in the lower main window once the instrument scan is complete. GPIB Device Found If your device did not appear, refer to. Also refer to.

MAX creates the necessary resources for VISA communication with your GPIB instrument. By double-clicking on the identified instrument (in the lower main window of Figure 4), you can access the instrument VISA Properties to change the VISA Resource Name of the device and communicate with it by clicking on Communicate with Instrument (SCPI commands), or Open VISA Test Panel (non-SCPI commands). Opening VISA Properties Tab For this example, you entered TDS2024 as our VISA Alias. It is important to choose an alias that you can immediately identify with the intended instrument.

This is especially important for large systems featuring many instruments. Using the VISA Interactive Control to Confirm Communication and More The VISA Interactive Control (VISAIC) is a standard software utility included with NI GPIB controller products. 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.

With the VISAIC utility, you can speed up application development by learning how to automate measurements with your instruments, uncover GPIB problems, and avoid headaches by identifying malfunctioning instruments. For Windows platforms, the VISAIC utility comes with online help that describes the applicable NI-488 functions and NI-488.2 routines, syntax, error codes, and status variables that offer the debugging information you need to solve problems. For a detailed discussion on how to use the VISAIC utility and the functions in the examples, refer to the VISA help file and NI-488.2 help file, respectively, that came with your GPIB controller. The following sections assume a basic knowledge of the VISAIC utility and GPIB. To launch VISAIC, click on Tools»NI-VISA»VISA Interactive Control (see Figure 6). Launch VISAIC Quickly Determining GPIB Addresses 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.

Figure 7 shows the VISAIC opening window. VISA Interactive Control Instruments must be powered on and connected to the GPIB controller to be recognized. If you have two or more instruments on the bus, you can disconnect all instruments except one to determine its address. By isolating each instrument on the bus and repeatedly refreshing (View»Refresh), you can quickly determine the address of each instrument. You also can use the Resource to Find field to query each instrument for an identification (ID) string. ID querying is discussed in the next section. Establishing Communication With Your Instruments Once you have determined the GPIB address of your instruments, you can easily establish communications to verify that you can send and receive data to and from the instrument.

Because most instruments are compliant with 488.2, you can query the instrument for its identification by sending it the.IDN? Instruments typically respond with the manufacturer's name, model name, and various alphanumeric characters that the manufacturer uses to track firmware revisions.

To communicate with your instrument at Address 4, follow these instructions: First, double-click the instrument in the VISAIC that you want to communicate with— in your case, GPIB0::4::INSTR. This opens a VISA Test Panel for your instrument.

With this test panel, you can set properties for your instrument communication as well as read and write to the instrument. VISA Test Panel (viWrite) From the viWrite tab, insert.IDN? N and then click Execute to send the 488.2 identification command.IDN?

To your instrument followed by a n termination character. Now from the viRead tab, select a count of 100, the length of your expected response, and then click Execute. Your instrument should return an identification string.

You have just confirmed communication with your instrument. You can repeat this process to confirm communication with all of your connected instruments.

VISA Test Panel (viRead) An Easy Way to Troubleshoot Instrument, Cable, and Power Problems Many times, systems are powered down and cables are disconnected from instruments for maintenance or to system configuration of the system changes. Unfortunately, engineers sometimes forget to reconnect all the cables and power up all the instruments. Alternatively, system power may be disrupted for a variety of reasons or the actual instrument may begin to malfunction. VISAIC is convenient for verifying that your instruments are still 'alive' on the bus.

Simply use refresh (View»Refresh) to check if a particular instrument is listening at its assigned GPIB address. If it is not, then you know to check cables, confirm power, and verify that the instrument is working properly. If there is a problem, you no longer see your device. This indicates that you should check for loose or disconnected cables, power disruption, or a malfunctioning instrument. 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. These productivity tools help you focus on developing your test applications instead of trying to track down obscure problems or establishing communications with your instruments. Once you have completed these steps, you need a fast way to progress from interactive mode to programming mode so you can immediately begin writing your tests without a tedious transition process.

The best way to achieve this is by using instrument drivers.

The compact NI GPIB-USB-HS transforms any computer with a USB port into a full-function, plug-and-play IEEE 488.2 controller for up to 14 programmable GPIB instruments. The GPIB-USB-HS takes advantage of Hi-Speed USB to provide superior performance of up to 1.8 MB/s with the standard IEEE 488 handshake and 7.7 MB/s with the high-speed IEEE 488 handshake (HS488). The small size and light weight of the GPIB-USB-HS make it ideal for portable applications using a laptop computer or other applications where the computer has no available internal I/O slots. The RoHS-compliant GPIB-USB-HS is shipped with NI-488.2 for Windows, Mac OS X, or Linux.
