ADLINK USB/LPCI/LPCIe-3488A GPIB interface card

Overall positioning and introduction of the product

GPIB (IEEE-488) is the mainstream parallel communication bus for industrial testing instruments, and the 3488A series is a fully compatible GPIB controller launched by Linghua. It is divided into three hardware models, suitable for laptops, desktop industrial computers, and short half height chassis:

1. USB-3488A: USB 2.0 external, portable for laptop scenarios, comes with a 2m matching cable, no external power supply required;

2. LPCI-3488A: Low profile half height PCI bus card, compatible with 3.3V/5V PCI slots;

3. LPCIe-3488A: Low profile half height PCIe bus card, compatible with modern PCIe industrial control hosts.

The entire series follows the IEEE488.2 standard, with a maximum of 14 GPIB instruments controlled in series by a single controller, and supports wired, star, or hybrid topologies; Built in read/write FIFO cache improves transmission stability, providing API compatibility with NI-488.2 and industrial VISA standard library, perfectly compatible with existing testing programs and instrument drivers. At the same time, Linghua’s PXI/PXIe controller product line is also equipped with GPIB solutions of the same specifications.

General core functional characteristics

1. Standard compatibility: fully compliant with IEEE-488 and IEEE488.2 instrument communication specifications;

2. Transmission performance

-LPCI/LPCIe-3488A maximum transmission rate: 1.2 MB/s;

-8-bit parallel data bus, three wire handshake protocol, byte by byte response, reliable transmission;

3. Hardware cache: Built in FIFO buffer to alleviate the speed difference between the host and the instrument;

4. Software ecosystem

-The driver API is compatible with NI-488.2 and supports the standard VISA library;

-Supporting interactive diagnostic tools for equipment debugging and troubleshooting;

5. Compliance certification: CE, FCC Class A electromagnetic compatibility certification.
