  • Extenders: NI GPIB extenders are designed to remove the restrictions on cable length and device loading imposed by the IEEE 488 (GPIB) standard. NI GPIB extenders can extend the maximum GPIB cable length up to 2 km.
  • Expanders/Isolators: NI GPIB expanders expand the number of GPIB devices that you can connect on the bus from 14 to 28 and provide an electrically isolated interface to one or more devices.
  • Mechanical Switches: NI GPIB mechanical switches can switch two or four GPIB sources into one common GPIB port.
