National Instruments AT-GPIB-TNT card. See photos below for actual item. Overview: The National Instruments AT-GPIB/TNT is a high-performance IEEE 488 interface for PCs with ISA slots. The NI TNT4882C ASIC makes the AT-GPIB/TNT a maximum-performance IEEE 488.2 interface board. The TNT4882C chip performs the basic IEEE 488 Talker, Listener, and Controller functions required by the most recent GPIB specification, IEEE 488.2. The AT-GPIB/TNT can sustain data transfer rates greater than 1.5 Mbytes/s using the IEEE 488.1 3-wire handshake. The AT-GPIB/TNT also implements the high-speed GPIB protocol (HS488). Features: • TNT 4882C ASIC • Maximum transfer rates (Windows) • 8-bit slot compatible with DMA disabled • Jumper-selectable hardware features • Choice of three 16-bit DMA channels ISA/AT • High-performance GPIB controllers for ISA • Plug and Play or manual resource configuration options • TNT4882C ASIC provides maximum IEEE 488.2 performance • Single-board GPIB controller/analyzer option • Low-cost GPIB-PCII/IIA on a half-size ISA board • NI-488.2 for Windows 2000/NT/Me/9x/3.1, DOS, OS/2 There are two versions of the National Instruments AT-GPIB/TNT -- the AT-GPIB/TNT (Plug and Play), and the Legacy AT-GPIB/TNT. Both are low-cost, high-performance IEEE 488 interfaces for computers with 16-bit ISA slots. The NI TNT4882C ASIC makes the AT-GPIB/TNT a maximum-performance IEEE 488.2 interface board. The TNT4882C chip performs the basic IEEE 488 Talker, Listener, and Controller functions required by the most recent GPIB standard, IEEE 488.2. The AT-GPIB/TNT can sustain data transfer rates of more than 1.5 Mbytes/s using the IEEE 488.1 3-wire handshake. The AT-GPIB/TNT implements the high-speed GPIB protocol (HS488), with data transfer rates of more than 1.6 Mbytes/s, or 2.9 Mbytes/s in an EISA computer. The AT-GPIB/TNT+ combines a GPIB controller and a GPIB analyzer on a single board. The GPIB-PCII/IIA is a low-cost interface on a half-size ISA board.
