The handy QUANCOM USB IEEE-488 / GPIB module converts any computer with a USB interface into a GPIB Bus Controller. The Module can be connected to the computer with up to 15 peripheral devices having IEEE488 interfaces.

The board is supported by the QLIB ( QUANCOM Driver Library ) and therefore programmable with most modern compilers and interpreters.

You need no knowledge in the driver development.

We implemented an command set which is the same for all operating systems. An application that uses our USB GPIB Module, which is generated for Windows 95 can be used directly on a Windows XP PC.

GPIB Test Application
This project shows how to program the card in Microsoft Visual-Basic

We implemented an command set which is the same for all operating systems. An application that uses our GPIB Card, which is generated for Windows 98 can be used directly on a Windows XP PC.

With the QLIB it is easy to create applications with Visual-Basic, Visual-C, Borland Delphi or other modern compilers. Even an interface to MS Excel, MS Access, HP VEE ( 3.1,4.0 and 5.0 ) or NI LabVIEW 4.0 thru LabVIEW 6.i is available. We included the VB GPIB Sample which shows how to program and test the card and it also includes the source code. This is a good starting point for your own applications.

The QLIB is an API which provides it's functions through a Windows DLL, so it is possible to use QLIB with all applications that allow access to external DLL Functions.


The following functions are available for the control of GPIB devices:

• Reading devices
• Writing devices
• Reading the status of the SRQ line ( The SRQ line is used by HPIB devices to interrupt the Active Controller, which then performs a Serial Poll or Parallel Poll to determine which device requested service, and why. The poll clears the SRQ. )
• Controlling Remote / Local Mode
• Polling the status byte ( In a serial poll, the Active Controller asks each device in turn to send back a status byte that indicates whether the device has asserted the SRQ. )
• Supported commands ( GTL = Goto Local, SDC = Selected Device Clear, GET = Group Execute Trigger, LLO = Local Lockout, DCL = Device Clear, Serial Poll Enable, Serial Poll Disable, UNL = Unlisten, UNT = Untalk )

Optional: GPIB Cable
