The National Instruments GPIB-ENET/100 is an Ethernet-to-GPIB controller that bridges networked computers to IEEE 488 instruments over TCP/IP networks. This device enables remote instrument control and multi-user access to GPIB systems without requiring physical proximity to test equipment. It automatically detects 10Base-T or 100Base-TX network speed and delivers sustained throughput up to 1450 kB/s—comparable to traditional plug-in GPIB boards.
