The National Instruments GPIB-140A is a high-performance GPIB (General Purpose Interface Bus) Extender designed to overcome the distance and loading limitations imposed by the IEEE 488 standard. This device ensures full compliance with both IEEE 488.1 and IEEE 488.2 standards, allowing GPIB network configurations to extend beyond the typical 20-meter limit by supporting up to 1 kilometer effortlessly through fiber-optic cabling. Utilizing an advanced buffered transfer technique, the GPIB-140A achieves data transfer rates exceeding 2.8 Mbytes/s when operating in HS488 protocol, making it one of the fastest extenders available. The implementation is straightforward, requiring no additional hardware or modifications to existing software applications, ensuring seamless integration into your current system. Each GPIB-140A continually monitors GPIB activity, converting GPIB signals into parallel or serial signals for efficient transmission. The compact design features dimensions of 3.5 × 5.65 × 1.62 inches and a weight of 0.55 lb. It can support up to 13 additional GPIB devices and is backed by a 2-3 year warranty. The product manual is readily available for download for user guidance and maintenance. For pricing and further information, please contact a sales representative.
