GPIB-140A | Bus extender
Model: GPIB-140A
Description: Bus extender
Description: Bus extender
1 km, GPIB Bus extender – The GPIB-140A extends the cable of the GPIB system by one kilometer without compromising the integrity of the GPIB and without software modification. The accessory uses buffered transmission technology with data transfer rates up to 1.1 Mb/s (IEEE 488.1) or 2.8 Mb/s (HS488). The GPIB-140A can also increase the maximum number of GPIB devices in a GPIB system from 15 to 26.

Buffered or unbuffered transmission
The National Instruments GPIB-140 / GPIB-140A Fiber optic GPIB extender removes restrictions on the IEEE 488 standard for cable length and device load while requiring little desktop space. The IEEE 488 standard specifies that the total cable length of a GPIB system cannot exceed 20 m and the maximum number of devices is 15. A pair of NI GPIB-140A/2 bus extenders can extend the cable length up to 2 km without compromising GPIB integrity or requiring any application modifications. The GPIB-140A can use fiber optic cables up to 1 km in length.
These GPIB-140A GPIB extenders use buffered transfer technology to transfer data at the fastest rates in the industry while keeping cabling costs to a minimum. Each extender has an error checking scheme to ensure an error-free link. Using the HS488 protocol, the maximum data transfer rate for extensions using the GPIB-140A extender exceeds 2.8 MB/s.
