The NI 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 and performs the basic IEEE 488 Talker, Listener, and Controller functions required by the most recent GPIB specification (488.2). The AT-GPIB/TNT can sustain data transfer rates greater than 1.5 Mb/s (488.1) and implements the high-speed GPIB protocol (HS488) for greater transfer rates.
There are two versions of the AT-GPIB/TNT: the AT-GPIB/TNT (Plug and Play), which features a jumperless configuration, and the legacy AT-GPIB/TNT, which uses DIP switches and jumpers to configure the interface. Both interfaces contain identical GPIB interface functionality.
