National Instruments (NI) recently introduced a new GPIB bus extender, Model GPIB-140A 186135G-01, designed to improve the performance of General Instrument Bus (GPIB) systems. The bus extender utilizes high-speed serial fiber transmission technology to achieve transfer rates in excess of 1.1 Mbytes/s (IEEE 488.1 standard) or 2.8 Mbytes/s (HS488 standard), significantly improving data transfer efficiency.
A notable feature of the GPIB-140A 186135G-01 bus extender is its scalability, which increases the number of devices that can be connected in a GPIB system from the standard 15 to a maximum of 26, greatly enhancing the system’s multi-device connectivity capabilities. In addition, the device uses buffered transmission technology, which is able to effectively increase the number of bus connections while maintaining high speed and efficiency, while keeping cabling costs to a minimum.
The bus extender has a wide range of applications, including but not limited to industrial automation, communication, computer network, etc., and can meet the needs of GPIB system expansion in a variety of application scenarios. In addition, the GPIB-140A 186135G-01 also supports a pair of bus extenders to extend the cable length up to 2 km without compromising the integrity of the GPIB or requiring any application modifications, which provides great convenience for applications that require long-distance communication.
The introduction of the GPIB-140A 186135G-01 bus extender further enrichis NI’s product line in the field of test and measurement, providing engineers and researchers with a powerful tool to implement more efficient and reliable data acquisition and control systems. With this device, users can easily overcome the limitations of the standard GPIB cable length and connect instruments further away from the controller, while maintaining high-speed data transfer and communication between devices.
In summary, the GPIB-140A 186135G-01 bus extender, with its high performance, high reliability and ease of installation, provides an ideal solution for a variety of applications requiring an increased number of bus connections.
