"GPIB for QNX 4" is an IEEE488 driver completely written from scratch and provides the whole functionality to drive any kind of GPIB-Device connected to the bus, regardless of the specialities of these devices. Even devices, that are not completely compatible to the IEEE488.2-standard can be controlled with some custom changes.

Nearly 15 years of experience in the marketplace of measurement-control, GPIB and automation and more than 10 years of experience with QNX, make it possible to offer a very stable product which is used in a great number of custom and even mission critical applications.

The driver itself was continuously developed and used in our own installations over a period of more than eight years. To meet our customer requirements we have now released a version, that can be purchased as a single product.

We have bundled the driver with good documentation, a help-system which plugs into the Photon-microGUI^®, an API-Interface which makes it possible to write your own applications, a shell-program to control the GPIB from the command-line and a photon program to do the same under control of the microGUI^®.

Support of the complete set of National Instruments' GPIB-controllers (including PCMCIA-Cards), a small memory-footprint, reliability and the option to drive more than one GPIB-Interface per computer makes the package an ideal choice for embedded solutions.

To meet the requirements of additional customer add-ons such as device-simulators and GPIB-analyzer-tools, we continuously develop such tools to make this top-selling product the first choice in GPIB-control with QNX.

Ask us for a completely free demo of our package to make your own evaluation or ask for a list of the ever growing number of companies and government-departments that use our GPIB-driver.

Our customers have free access to new updates and minor-release-changes. Only a small amount of money must be paid for major release changes. As a customer you also have free access to all the beta-versions of additional addons you get an additional discount for new tools if you have been a beta tester before.

Driver-Capabilities

According to the IEEE488.2-Standard, the driver provides the following capabilities if used with a new National Instruments' GPIB/TNT^® Interface:

^* Some functions are provided by the Interface, but are currently only supported by the software if the low-level-interface is used. Addons to the driver to make it possible to become a complete GPIB-device using the high-level-Interface are included until mid 1998.
Using the high-level interface, currently only a complete set of functions to provide the controller-capability are included.

General and Device-dependent capabilities:

Supported GPIB-Cards:
INES-IEEE488, GPIB-PC2A-1, AT-GPIB.2, AT-GPIB/TNT, NI-488.2 and PCMCIA-GPIB and GPIB+

Number of supported Cards:
As many as the computer is able to hold

Number of supported devices:
30 Devices per driver/card. Each device can be configured individually (device-speed. End of Stream Termination and method).
Complete secondary addressing

Memory Requirements:
1 MB of disk-space for the complete set of programs, sample code and online help (may be tailored to meet an embedded system)
70 KB of memory per supported card

Driver capabilities and software:
