   While Prologix GPIB-USB controller provides many of the same features as GPIB-USB controllers from other vendors, it is much easier to use. Prologix GPIB-USB controller provides a virtual serial interface to communicate with instruments, while handling all GPIB protocol details for you. As a result, you can communicate easily with instruments using any terminal program instead of having to write custom programs using vendor supplied library. Please see the Manual for a complete list of features.

4. Is Prologix GPIB-USB controller compatible with National Instruments LabVIEW, Agilent VEE, and other test frameworks?

   Yes. Prologix GPIB-USB controller provides a virtual serial interface to communicate with instruments, while handling all GPIB protocol details for you. Any test framework, or programming environment, that provides access to serial ports is compatible with Prologix GPIB-USB controller. For example, you may use NI LabVIEW Serial VIs or NI VISA VIs. Also, see LabVIEW samples on communicating with the controller using D2XX drivers.

5. How do I use Prologix GPIB-USB controller with LabVIEW?

   Prologix GPIB-USB controller provides a virtual serial interface to communicate with instruments. Therefore you may use LabVIEW serial port functions or VISA serial port functions to talk to Prologix controller and attached instruments. Please see LabVIEW sample program in the Resources section.

   The basic steps to communicate with an instrument in LabVIEW are as follows:

   1. Open USB Serial Port. Port settings, such as baud rate, do not matter.
   2. Send ++mode 1 terminated with Line Feed. See Manual for command details.
   3. Send ++auto 1 terminated with Line Feed. See Manual for command details.
   4. Send ++addr X terminated with Line Feed, where X is the GPIB address of the instrument. See Manual for command details.
   5. Send a valid instrument command terminated by Line Feed.
   6. Read USB Serial Port for instrument response.

18. Which commands do I use to control my instrument?

    Refer to the programming manual of your instrument for commands accepted by your instrument.

19. How do I create programs to control instruments, and acquire data, using Prologix GPIB-USB controller?

    Any programming language and environment that provides access to serial ports may be used to develop programs to control instruments using the Prologix GPIB-USB controller. Please see sample programs in the Resources section. Also, check out Ulrich Bangert's EZGPIB, an easy to use data acquisition tool for use with Prologix GPIB-USB controller.

20. Can Prologix GPIB-USB controller control multiple instruments?

    Yes. Specify the GPIB address of the instrument to control using the ++addr command. All subsequent instrument commands are sent to the specified address. When you want to control a different instrument, issue another ++addr command with the new address. See User Manual for complete details and samples.

21. Why is the instrument not responding to commands?

    Some common reasons are:
    • Wrong serial port is being used.
    • Prologix GPIB-USB controller is not in CONTROLLER mode.
    • Prologix GPIB-USB controller does not have the correct instrument GPIB address.
    • Read-after-write may not be enabled. See User Manual.
    • Instrument is not in TALK/LISTEN mode. Check instrument front panel menu, or back side DIP switch.
    • Prologix GPIB-USB controller is not securely connected to instrument. Try using a GPIB cable, if direct connection is not secure.
    • Other instruments on the GPIB bus may be interfering. Disconnect (not just power down) all instruments except the one being used.
    • Command is not recognized by the instrument. Check instrument programming manual.

22. Why is the instrument reporting QUERY UNTERMINATED or ERROR -420 error when using Prologix GPIB-USB controller?

    After sending a command to an attached instrument, Prologix GPIB-USB controller will address it to talk to read back the response. If the command does not generate a response (often called non-query commands), some instruments will generate the QUERY UNTERMINATED error when addressed to talk. In effect the instrument is saying, you have asked me to talk but I have nothing to say. The error is often benign and may be ignored.

    However, if you wish to avoid the error use the ++read command to read instrument responses. For example:

    ++auto 0	—	Turn off read-after-write
    SET VOLT 1.0	—	Non-query command
    *idn?	—	Query command
    ++read eoi	—	Read until EOI is asserted by instrument
    'HP54201A'	—	Response from instrument

    See User Manual for complete details.
