Product Details:

NATIONAL INSTRUMENTS AT-GPIB/TNT is a high-performance ISA AT bus GPIB interface card, built with TNT4882C ASIC chip, fully compliant with IEEE 488.1 and IEEE 488.2 standards. It supports HS488 high-speed transmission protocol, the transfer rate can reach 1.5 Mbytes/s under standard three-wire handshake, and up to 3.4 Mbytes/s when matched with EISA host. This board works as full-function GPIB talker, listener and system controller, supports DMA and interrupt transmission modes, has onboard FIFO buffer to reduce CPU occupation. There are multiple versions including jumper configuration version, PnP plug-and-play version and AT-GPIB/TNT+ integrated analyzer version. It adopts standard GPIB connector on front panel, powered by +5V from ISA slot, and supports resource configuration via jumper or NI PnP tool. This legacy ISA GPIB board is end-of-life, available stock are refurbished replacement spares for vintage test and measurement systems.

This GPIB controller card connects PC AT compatible industrial computer to GPIB instruments, realizing instrument communication, parameter reading and remote control. It supports NI-488.2 driver, compatible with LabVIEW, NI-488.2M and DOS, early Windows development environment. It can connect multiple GPIB test instruments such as power supply, oscilloscope, signal generator and multimeter on one bus, build automated measurement and calibration platforms. Optimized ASIC design ensures stable handshake and high reliability in long-time measurement tasks, and it maintains good compatibility with old industrial measurement software for ISA bus platform.

It adopts standard ISA AT full-length board mechanical specification, draws power from ISA slot. Front panel is equipped with standard GPIB connector, simple status indicator. Hot swap operation is not supported; computer power must be cut off before installation or removal. The PCB and soldering assembly meet industrial shock and vibration requirements for cabinet installation.

It is widely deployed in laboratory calibration stations, aerospace automatic test equipment, semiconductor test benches and legacy automated measurement systems requiring GPIB instrument control. Typical application scenarios include old GPIB test bench interface replacement, multi-instrument synchronous measurement system maintenance and vintage automation platform retrofit. Automation integrators select this NI AT-GPIB/TNT for its TNT4882C ASIC,HS488 high speed,IEEE488.2 controller,ISA AT bus interface.
