Description
Product details:
The National Instruments GPIB-140A a Fiber Optic GPIB expander eliminates the limitations of the IEEE 488 standard on cable length and device load while requiring little to no desktop space. The IEEE 488 standard states that the total cable length of a GPIB system cannot exceed 20 meters, and the maximum number of devices is 15. A pair of NI GPIB-140A/2 bus extenders can extend cable lengths up to 2 km without compromising the integrity of GPIB or requiring any application modifications. The GPIB-140A can use up to 1km of cable.
Features:
High-speed serial fiber optic transmission
Transfer rate over 1.1 MB/SEC (IEEE 488.1) or 2.8 MB/SEC (HS488)
Expand the number of GPIB devices to 26
Buffered or unbuffered transmission
These GPIB extenders use buffered transfer technology to transfer data at the fastest speeds in the industry while keeping wiring costs to a minimum. Each extender has an error-checking scheme to ensure error-free linking. Using the HS488 protocol, the GPIB-140A expander has a maximum data transfer rate of over 2.8 megabytes per second.
