GPIB Expansions and Extensions

GPIB Expansions and Extensions


Burst the limits of GPIB!

With these extenders and expanders you can pass the maximum distance of 20 m established by the GPIB standard, using fibre optics or copper cables. As an option you can also opto-isolate the bus sections from each other. And you can expand the maximum number of bus devices of 15 with these boxes.
