What is GPIB USB?

Product Overview The GPIB-USB-HS is an IEEE 488 controller device for computers with USB slots. The GPIB-USB-HS achieves maximum IEEE 488.2 performance. With no GPIB cable required for instrument connection, you can use the Hi-Speed USB port to control up to 14 programmable GPIB instruments.

What is the difference between GPIB-USB-HS and GPIB-USB-HS+?

The primary differences between the GPIB-USB-B and the GPIB-USB-HS are listed in the table above and are otherwise interchangeable. The GPIB-USB-HS is considered a mature product. NI recommends customers migrate to the GPIB-USB-HS+ to take advantage of newer technologies, lower prices, and longer-term availability.

How do I use GPIB HS USB?

The GPIB-USB-HS does not require a GPIB cable for connecting to your instruments. You can attach it directly to the GPIB port on your instrument and then connect the USB cable to the USB port on your computer.

What is GPIB interface?

The GPIB interface, sometimes called the General Purpose Interface Bus (GPIB), is a general purpose digital interface system that can be used to transfer data between two or more devices. It is particularly wellsuited for interconnecting computers and instruments.

How do I connect to GPIB?

The fastest and easiest way to connect instruments to a PC is to use a USB/ GPIB converter — a simple cable with a GPIB plug on one end and a USB plug on the other — that provides a direct connection from the USB port on your PC to GPIB instruments.

How does a GPIB work?

GPIB Devices can be Talkers, Listeners, and/or Controllers. A Talker sends data messages to one or more Listeners, which receive the data. The Controller manages the flow of information on the GPIB by sending commands to all devices. A digital voltmeter, for example, is a Talker and is also a Listener.

How do I connect my GPIB to my laptop?

Why is GPIB still used?

GPIB is still popular among test engineers in the aerospace and military industries because their products have long life cycles; 20 years is not uncommon. Test equipment manufacturers are trending toward making GPIB an option to minimize the cost of the basic instrument.

Is GPIB hot swappable?

With the 82357B USB/GPIB interface and its convenient plug-and-play feature, you just plug and go. It is also hot pluggable, making it easy to connect and disconnect without having to shut down the computer.

What is a GPIB address?

A GPIB address is made up of two parts: a primary address and an optional secondary address. Most devices just use primary addressing. The GPIB Controller manages the communication across the GPIB by using the addresses to designate which devices should be listening or talking at any given moment.

How can I change my GPIB address?

Setting the GPIB

Press System key.
Press Misc Setup > GPIB Setup> Talker/Listener Address.
Enter the address using the ENTRY block keys on the front panel.

What is the GPIB interface?

How many devices can be configured in GPIB?

For example, the Interface Clear (IFC) line, when asserted, sends the Interface Clear command to every bus device, causing each to reset its IEEE-488 bus interface. The GPIB standard normally permits up to 15 devices to be configured within one system.

How do I change the GPIB bus address of my Device?

Newer GPIB devices like ICS’s Minibox interfaces use SCPI commands to change and set their GPIB bus address. Use the ‘SYST:COMM:GPIB:ADDR aa’ command where aa is the new GPIB address to change the address setting. The address change is immediate. Use the ‘*SAV 0’ command to save the new setting.

What is the maximum length of a GPIB cable?

However, the GPIB specification limits the total length of all cabling used to interconnect devices on a common bus to 20 m, or 2 m times the number of interconnected devices (up to 20 m). Cable lengths between devices may vary, as long as total cable length does not exceed these restrictions.
