1.3 Specifications 1.3.1 GPIB Bus Properties X Up to 14 instruments can be connected to one controller X Maximum 1.5 MB/s data transfer rate X Cable length Z 2 meters between each instrument (suggested) Z 20 meters total cable length X Data transfer mode: 8 bits parallel X Handshake: 3 wire handshake, reception of each data byte is acknowledged 1.3.
1.3.
1.4 Software Support The ADLINK LPCI-3488A and PXI-3488A GPIB interface cards provide a device driver package: ADL-GPIB for Windows 98/2000/ XP/Vista. The ADGPIB driver package also provides a diagnostic utility to test GPIB interface cards, as well as programming samples and source code examples for Microsoft Visual C++. The ADL-GPIB driver package can be found in the included All-in-one CD. Please refer to the Software Installation section (2.6), on page 16 for detailed software installation instructions.
2 Installation This chapter outlines the contents of package, describes unpacking information, and describes how to install the hardware and software. 2.1 Contents of Package 2.1.1 LPCI-3488A The LPCI-3488A includes the following items: X LPCI-3488A X An additional low-profile bracket X ADLINK All-in-One CD X This User’s Manual 2.1.
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.
2.3 Mechanical Drawing 2.3.
2.3.2 PXI-3488A Figure 2-2: PCB Layout of the PXI-3488A The ADLINK PXI-3488A is packaged in a Eurocard form factor compliant with the PXI Specification and measuring 160 mm in length and 100 mm in height (not including connectors). The IEEE488 standard 24-pin connector is located at the front panel and the J1 IEC connectors in the rear are used to link the chassis backplane.
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 information and on known 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.
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.
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.

2.6 Software Installation ADLINK GPIB interface cards are delivered with an ADL-GPIB driver package for Windows 98/2000/XP/Vista. The ADL-GPIB is designed to be fully compatible with your current applications and includes APIs and a binary-compatible gpib-32.dll for users using LabVIEW1, LabWindow/CVI2, VC++, VB, and Delphi. ADLINK GPIB interface cards also adequately support VISA to work with most available instrument drivers. Please visit the ADLINK website (www.adlinktech.

2.6.2 Using the ADLINK GPIB Utility The ADL-GPIB driver package also provides an “ADLINK GPIB Utility” utility program to diagnose and verify GPIB connections. It is located on the All-in-one CD: x:\ADLINK\ADL-GPIB\Utility\GPIB Utility.exe. 1. Launch GPIB Utility.exe. A window appears to show all installed GPIB interfaces and instruments 2. Click on a GPIB interface (GPIB0, GPIB1, etc.) and select “Setting” > “GPIB Preference”.

3. Double click on a connected GPIB instrument. A ‘”GPIB Interactive control” dialog appears to allow write command strings to be inputted into the GPIB instrument and read the result.
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.
GPIB BUS Type Function Pin No.
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.
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.
