【英文介绍】

National Instruments GPIB-SPRC-B IEEE 488 interface board

Features:

GPIB interface of Sun SPARCstation

S-bus DVMA data transfer for optimal performance

Transfer rate - 1.4MB /s using 1EEE 488.1; HS488 is 3.6 MB/s

Fully compatible with IEEE 488.2

The National Instruments GPIB-SPRC-B is a low-cost, high-performance IEEE 488 interface kit for the Sun SPARCstation family of workstations equipped with an S-bus slot. The NI TNT4882C ASIC makes SB-GPIB/ TNT the most high-performance IEEE 488.2 interface board. The TNT4882C chip performs the basic IEEE 488 speaker, listener, and controller functions required by the IEEE 488.2 standard. With TNT4882C and S-bus direct Virtual Memory access (DVMA) transmission, data transfer speeds can reach 1.4 MB/s using IEEE 488.1 3-wire handshake. TNT4882C can significantly improve the throughput of associated multi-tasking Solaris driver software. SB-GPIB/TNT also implements the high-speed GPIB protocol (HS488), so data transfer speeds can exceed 3.6 MB/s.

Gpib-sprc-b is a high-performance GPIB interface board. The GPIB-SPRC-B interface board is assembled by National Instruments. The NI GPIB-SPRC-B is available for order with part number 776789-01. The GPIB-SPRC-B board belongs to the GPIB family of boards from National Instruments. The NI GPIB-SPRC-B board runs with the NI-488.2 driver software. The interface board can be used with LabVIEW and LabWindows/CVI for recommended software.

NI GPIB-SPRC-B is compatible with the Solaris operating system. The GPIB-SPRC-B interface board consists of the SB-GPIB/TNT board and NI-488.2 for Solaris. SB-GPIB/TNT can be inserted into a single wide main S-bus slot. Regular IEEE 488 cables can connect a circuit board to up to 14 devices. Multiple SB-GPIB/TNT boards can be inserted into a single computer to control multiple devices.

The interface board is designed to meet IEEE 488.2 standard compatibility. The GPIB-SPRC-B interface board provides the maximum GPIB data transfer rate. The GPIB-SPRC-B board can perform high-speed (HS-488) transfer rates in excess of 3.6 MB/s. The board supports an IEEE 488.1 data rate of over 1.4 MB/s. National Instruments GPIB-SPRC-B has software-controlled configuration options. NI GPIB-SPRC-B does not require any jumpers.

This IEEE 488 interface board was developed specifically to provide S-bus DVMA data transmission. The board is constructed with TNT4882C ASIC chip. Gpib-sprc-b can control the signal, which is used to render fast GPIB events. The NI GPIB-SPRC-B interface board is fully software compatible with all older versions of the SB-GPIB interface board at the time of manufacture.
