The National Instruments part number 776836-01 designates the AT-GPIB/TNT AT Series IEEE 488.2 Interface Board, which is engineered to convert any ISA or EISA bus computer into a comprehensive GPIB Talker/Listener/Controller. This robust module is equipped with the TNT4882C ASIC, enabling compatibility with the NI-488.2M software and adherence to the Plug and Play ISA Standard, ensuring a seamless user experience. The board supports the HS488 high-speed protocol, allowing a maximum data transfer rate of up to 2.2 Mbytes/s in an ISA bus configuration, while also facilitating 1.5 Mbytes/s via the 3-Wire (IEEE 488) standard. Users can connect up to 14 instruments using standard GPIB cables, with the option to extend this capacity through additional bus extenders. The device operates on a +5 VDC power from the PC AT I/O channel, typically consuming 120 mA, with a peak requirement of 200 mA. Physically, the 776836-01 measures 4.2 inches by 6.5 inches and utilizes an IEEE 488 Standard 24-pin connector for I/O functions. Designed for reliable operation in environments ranging from 0° to 55° C and 10% to 90% relative humidity, the module is also capable of being stored in more extreme conditions, from -20° to 70° C and 5% to 90% relative humidity. It is supported across major operating systems, including Windows NT, Windows 95, and DOS, with the NI-488.2M software package providing a kernel device driver, diagnostic tests, configuration utilities, and comprehensive software development support.
