ND GPIB-SYSTEM¶

Introduction¶

The GPIB system is an IEEE 488 and IEC 625 standard multiuser interface system for programmable instrumentation. It is intended for applications like laboratory instrumentation in hospitals and research institutions, and for automatic test systems. However, it can also be used to interface peripherals like plotters or printers, if these are IEEE or IEC compatible.

The interface system can be used for:

Measurements requiring high reproducibility and accuracy
Measurements requiring simultaneous testing of input and output characteristics
Measurements requiring immediate further processing of the measured data to allow decision-making
Measurement procedures which are extremely diversified or constantly recurring
Procedures measuring many parameters
Measurements with only a few interesting results

The GPIB system is delivered with a GPIB software packet based on FORTRAN callable routines for the different functions of the module.

There are routines to:

Read data from device
Write data to device(s)
Transfer data between devices
Trig and clear device(s)
Set device(s) in local mode
Parallel configuration of device(s)
Pass control to device
Configure the parallel or serial poll status for GPIB module
Reserve device(s) for a user
Release device(s) for a user
List system device(s)
List device(s) reserved for a user

ND GPIB-SYSTEM¶

Product Description¶

The GPIB system on ND-100 is a multiuser system with a maximum of 16 users. The microprocessor on the GPIB module takes care of creating new users, deleting old users, reserving devices for a user, enabling for a new device that has been connected to the bus, deleting old devices, etc.

The standard version (ND 108550) allows for: - Maximum 15 devices on one bus - Maximum 20 meters total cable length - Maximum 500,000 bytes/s data rate

The remote option (ND 108560) avoids these limitations in the IEEE-488 or IEC-625 standards. On the ND-100 GPIB card, the 16 signals in the GPIB are translated into 20 pairs of signals in a differential bus. In a memory box containing one card, these 20 pairs of signals are translated back to the 16 GPIB signals.

This differential bus can be a maximum of 100 meters long. In this way, 13 devices may be connected to the ND-100 and another 14 connected to the remote box. This makes 28 devices connected to each other, using only one interface card.

Software¶

The GPIB module is an input/output unit – with or without direct memory access (DMA).

The contact between the programmer and the GPIB module connected to the devices is through:

Sending device dependent data with or without DMA
Receiving device dependent data with or without DMA
Receiving interface status like parallel poll, serial poll and error status through the microprocessor
Sending special messages to the module, like word counter, memory address and control word
Sending commands to the microprocessor on the module
Receiving status from the module, like interrupt status, state status, memory address
