AT-GPIB/TNT (NATIONAL INSTRUMENTS)

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). There are three versions of the AT-GPIB/TNT - the AT-GPIB/TNT (Plug and Play), which features a jumperless configuration; the legacy AT-GPIB/TNT, which uses DIP switches and jumpers to configure the interface; and the AT-GPIB/TNT+, which is a combination of an AT-GPIB/TNT (Plug and Play) and a GPIB analyzer in one board. All three interfaces contain identical GPIB interface functionality.
