Description
The National Instruments NB-GPIB/TNT IEEE 488 Interface Board is a specialized solution designed by National Instruments for Macintosh NuBus Computers, providing essential functions such as control, talking, and listening. It is equipped with a TNT4882C main chip, enabling impressive data transfer rates of up to 1.3 MB/sec under standard conditions and further acceleration up to 2.3 MB/sec when utilizing the HS488 high-speed protocol, supported by a 3-wire handshake protocol.
This interface board is distinguished by its FCC Class A EMI certification, ensuring compliance with electromagnetic interference standards. It shares similarities with the NB-GPIB-P/TNT model, which incorporates both NAT4882 and Turbo488 ASIC chips—the latter boosts the transfer speed up to 850 kB/sec. Additionally, the board supports DMA transfers, facilitated by an RTSI connector, and can manage connections with up to 14 devices simultaneously. The required driver software for optimal functioning is NI-488.2, tailored for the Macintosh operating system.
