Description
The National Instruments GPIB-140A GPIB Extender is a high-performance hardware accessory designed to extend GPIB systems over long distances. The part number for this device is 182783B-01, and it is known by alternate part numbers including 777997-01, 777997-02, 777997-03, 777997-04, 777997-05, and 777997-06, making it a versatile component for various setups.
Falling under the GPIB category, this extender is compatible with both the IEEE 488.1 and IEEE 488.2 standards, ensuring it can be integrated into a wide range of GPIB systems. It is specifically designed to facilitate the extension of GPIB systems to a maximum system length of 1 km when using two extenders, which is particularly useful for setups requiring long-distance connections.
The GPIB-140A supports the use of up to 1 km of fiber-optic cable for maximum cable length, providing a secure and reliable means of extending the reach of GPIB networks. This capability is enhanced by the extender’s use of buffered transfer technique, which not only ensures the integrity of data over long distances but also allows for a maximum transfer rate that is faster than 2.8 Mbytes, adhering to the HS488 protocol.
An important feature of the GPIB-140A is its software transparency, meaning that the extension process does not require any changes to the existing software configurations, making it an incredibly convenient solution for expanding the reach of GPIB systems without the need for extensive modifications or programming.
