IEEE 488 GPIB data transfer line for use with the GPIB interface (IEEE 488). It is widely used in scientific research, testing, manufacturing and productionline testing, and is favored by many universities, research institutions and some production enterprises. 24pin copper insert (GPIB 24pin interface): 24pin copper insert provides durable contact life and reliable data transfer. Metal bus interface: Supports bitparallel and byteserial bidirectional transmission. Connection mode is bus mode with no intermediate unit; devices connect directly in parallel to the bus. Metal construction provides longer service life. Transmission distance and performance: Transmission distance up to 20 meters. Signal transmission speed generally 500 kb/s, transmission speed 1 m/s. The bus can connect up to 15 devices. Use scenarios: In university laboratories or research institutes to interconnect multiple instruments for coordinated experiments and data collection. On testing and production lines to transfer data between test instruments and data acquisition systems. In scientific research environments requiring reliable, longdistance GPIB data transfer across several devices without intermediate controllers.
