GPIB-130

National Instruments GPIB-130 Bus Extender
Features

• High-Speed Parallel Transmission
• Extends Maximum GPIB Cable Length to 300 m
• Transfers More than 900 KB/s
• Buffered or Unbuffered Transfers

The National Instruments GPIB-130 Bus Extender removes the restrictions on cable length and device loading imposed by the IEEE 488 standard while requiring virtually no desktop space. The IEEE 488 standard specifies that the total cable length for a GPIB system cannot exceed 20 m and the maximum number of devices is 15. The NI GPIB-130 can extend the distance up to 300 m with a high-speed parallel transmission.

These GPIB extenders use a buffered transfer technique to transfer data at the fastest rates in the industry, while keeping the cabling cost at a minimum. Each extender has an error-checking scheme to ensure an error-free link. The GPIB-130 extenders can achieve rates of more than 900 kbytes/s.
