High-Speed, Multi-Input Serial-Interfacing System for a Computer with Simultaneous Back-Up Recording on Magnetic Tape. Report No. M52

摘要

A system has been developed that interfaces nuclear-instrument data modules and a multichannel analyzer into a computer. The interface converts 4-bit binary-coded decimal (BCD) data into 8-bit packed BCD data, and converts the parallel data into serial data. The data are transmitted up to a distance of 500 m at a transfer rate of 153,6 kbaud via an RS422 transmission link to a central computer system. One or more multichannel analyzer systems can be connected to the system via a routing device. The routing device serves these analyzers on a first-come-first-served mode. The data transmitted to the computer system are recorded simultaneously on a digital magnetic-tape drive to provide a back-up facility. (ERA citation 08:032365)
