1 Introduction

1.1 Overview

ADLINK’s LPCI-3488A and PXI-3488A GPIB controller interface cards are fully compatible with the IEEE488.2 instrumen tation co ntrol and communication standard and are capable of controlling up to 14 stand-alone instruments via IEEE488 cables. The LPCI3488A and PXI-3488A are designed to meet the requirements for high performance and maximum programming portability. They were developed using ADLINK’s intellectual property in FPGAs which incorporates the GPIB controller , provides reliable GPIB bus control capability , and support s a transfer rate up to 1.5 MB/s. With

APIs that are compatible with National Instruments VISA support, the LPCI-3488A and PXI-3488A offer the be st compatibility with your existing applications and instrument drivers.

1.1.1 Performance

ADLINK’s expertise in PCI and PXI interface cards was leveraged when developing these newly designed GPIB interface card. The LPCI-3488A, which is the low-profile PCI form factor, supports both 3.3 V and 5 V PCI buses and can be adapted to most industrial and desktop computers. The PXI-3488A is compliant with PXI specification Rev. 2.0 and can be used with most PXI and CompactPCI system. A 2 KB FIFO is placed between the GPIB bus and PCI controller to buffer GPIB read/write operations. This FIFO eliminates the gap between the slow GPIB bus (~1.5 MB/s) and the fast PCI bus (132 MB/s), and dramatically increases overall system performance.

2.2 Unpacking

Both the LPCI-3488A and PXI-3488A contain electrostatic sensitive components that can be easily be damaged by static electricity.

Therefore, these modules should be handled on a grounded antistatic mat. The operator should be wearing an anti-static wristband, grounded at the same point as the anti-static mat.

Inspect the module for obvious damage. Shipping and handling may cause damage to the module. Be sure there is no shipping and handling damage on the module before continuing.

Note: DO NOT APPLY POWER TO THE CARD IF IT HAS BEEN

DAMAGED.

2.4 PCI Configuration

2.4.1 Plug and Play

As a plug-and-play component, the card requests an interrupt number via its PCI controller. The system BIOS responds with an interrupt assignment based on the card in format ion and on know n system parameters. These system parameters are determined by the installed drivers and the hardware is acknowledged by the system.

2.4.2 Configuration

Board configuration is accomplished on a board-by-board basis for all PCI/PXI boards in the chassis. Because configuration is controlled by the system and software, there is no jumper setting required for base-address, DMA, and interrupt IRQ.

The configuration is subject to change with every boot of the system as new boards are added or removed.

2.4.3 Troubleshooting

If the system doesn’t boot or you experience erratic operation with the PCI/PXI board in place, it’s likely caused by an interrupt conflict (perhaps the BIOS settings are incorrectly configured). In general, the solution, once you determine it is not a simple oversight, is to consult the BIOS documentation that comes with your system.

2.5 Hardware Installation

2.5.1 LPCI-3488A Installation Procedures

Please follow the instructions to install LPCI-3488A in your system.

1. Turn off the computer

2. Turn off all accessories (printer, modem, monitor, etc.)

connected to the computer.

3. Open the computer case.

4. Select a 32-bit PCI slot. PCI slots are shorter than ISA or

EISA slots, and are usually white or ivory.

5. Before handling the PCI cards, discharge any static

buildup on your body by touching the metal case of the

computer. Hold the edge of the board and do not touch

the components.

6. Position the board into the selected PCI slot.

7. Secure the card in place at the rear panel of the system.

8. Replace the computer case cover.

Turn on the computer, and install the software according to the instructions in the Software Installation section (2.6), on page 16.

2.5.2 PXI-3488A Installation Procedures

Please follow the instructions to install the PXI-3488 into your PXI chassis.

1. Turn off the system.

2. 2.Align the module’s edge with the card guide in the PXI chassis.

3. 3.Slide the module into the chassis, until resistance is felt from the PXI connector

4. 4.Push the ejector upwards and fully insert the module into the chassis.

5. 5.Once inserted, a “click” can be heard from the ejector latch.

6. 6.Tighten the screw on the front panel.

Turn on the computer, and install the software according to the instructions in the Software Installation section (2.6), on page 16.

2.5.3 Cabling

The following connection configuration can ensure that the GPIB throughput achieves optimal performance. These configurations include the number of instruments and cable distances:

X Cable lengths should be no longer than 4 meters (2 meter

lengths maximum is suggested).

X The total GPIB BUS distance should be less than 20 meter. X The total number of devices must less than 15 (including

computer itself), and at least two-thrids (2/3) of the devices are powered on.

Devices can be connected in a linear configuration, star configur ation, or combination the two. The following figures show both linear and star connections.

Note: For a star connection, the total current load will be less if

there are less than three cable connections on an individual instrument.

3 Operation Theory

This chapter describes the operation theory of GPIB bus and the basic architecture of ADLINK’s GPIB interface cards.

3.1 Connection Configuration

The GPIB bus has 24 lines which are divided into 16 signal lines and 8 ground return or shield drain lines. The 16 signal lines can be divided into 8-bit parallel data transfer bus and 8 control lines. The 8 control lines contain 5 system management lines and 3 handshake lines.

3.1.1 Data Lines

DIO1 to DIO8 carry both data and command messages. All commands and most data use 7-bit ASCII codes, the 8th bit, DIO8, is either unused or used as a parity check.

3.1.2 Handshake Lines

Three handshake lines control the transfer of data/messages between devices.

X DAV (Data Valid): Indicates the condition (availability and

validity) of information on the DIO signal lines

X NRFD (Not Ready For Data): Indicates the condition of

readiness of the device(s) to accept data

X NDAC (Not Data Accepted): Indicates the condition of

acceptance of the data by the device

3.1.3 System management lines

Five system management lines manage the flow of control and data bytes across the interface.

X EOI (End or Identify): Used (by a talker) to indicate the end

of a multi-byte transfer sequence or used in conjunctio n with ATN (by a controller) to execute a polling sequence

X IFC (Interface Clear): Used (by a controller) to place the

interface system, portions of which are contained in all interconnected devices, in a known quiescent state

X SRQ (Service Request): Used by a device to indicate the

need for attention and to request an interruption of the current sequence of events

X ATN (Attention): Used (by a controller) to specify how data

on the DIO signal lines are to be interpreted and which devices must respond to the data

X REN (Remote Enable): Used (by a controller) in conjunction

with other messages to enable or disable one or more local controls that have corresponding remote controls.

3.2 ADLINK GPIB Interface Cards Block Diagram

ADLINK’s LPCI-3488A and PXI-3488A GPIB interface cards include a 2 KB FIFIO inside the FPGA IP to maximize data transfer rates. Its state-of-the-art state machine in the the CPLD coordinates the data flow between the PCI controller, FIFO and GPIB bus.

The FIFO can buffer data from the master (either from the PCI controller or external device) when the target is busy. Efficiency is thus significantly improved when transferring large blocks of data.
