Description
The National Instruments GPIB-140A/2 GPIB Extender is a crucial component of the National Instruments GPIB-140A Series, designed to overcome the IEEE 488 standard’s limitation which restricts cable length to 20 meters without an extender. By enabling an extension of up to 2 kilometers, this device significantly expands the operational range of GPIB systems.
With the capacity to support up to 28 devices per system, the GPIB-140A/2 facilitates larger and more complex system configurations beyond the typical 15 devices allowed by the IEEE 488 standard. Users can choose between buffered and unbuffered modes for data transmission, depending on their requirements for speed and data integrity.
By default, the device is set to operate in unbuffered mode, ensuring accurate data exchanges, but it can be easily reconfigured using the DIP switches provided on the GPIB-140A/2 unit. This flexibility in configuration, combined with the use of a fiber-optic cable communication protocol, makes the NI GPIB-140A/2 a versatile solution for extending GPIB networks.
The extender’s part numbers include 777998-01, 777998-02, 777998-03, 777998-04, 777998-05, and 777998-06, ensuring compatibility with a range of setups and user needs.
