GPIB-SPRC-B / SB-GPIB

National Instruments GPIB-SPRC-B / SB-GPIB/TNT High Performance IEEE 488 Interface
Features

• GPIB interface for Sun SPARCstations
• SBus DVMA data transfers for maximum performance
• Transfer rates - 1.4 Mbytes/s using 1EEE 488.1; 3.6 Mbytes/s with HS488
• Completely IEEE 488.2 compatible

The National Instruments GPIB-SPRC-B is a low-cost, high-performance IEEE 488 interface kit for Sun SPARCstation Series workstations equipped with SBus slots. The NI TNT4882C ASIC makes the SB-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 IEEE 488.2 standard. With the TNT4882C and the SBus Direct Virtual Memory Access (DVMA) transfers, data transfers can reach 1.4 Mbytes/s using the IEEE 488.1 3-wire handshake. The TNT4882C can significantly increase the throughput of the associated multitasking Solaris driver software. The SB-GPIB/TNT also implements a high-speed GPIB protocol (HS488), so you can have data transfers of more than 3.6 Mbytes/s.
