GPIB-140A IN 光纤GPIB延长器 扩展器

The GPIB-140A is a fiber optic GPIB extender that extends a GPIB system by 1 km without compromising the integrity of the GPIB or requiring any software modifications. The device uses buffered transmission technology, and the data transfer rate can reach 1.1 Mb/s (IEEE 488.1) or 2.8 Mb/s (HS488). The GPIB-140A also increases the maximum number of GPIB devices in the system from 15 to 26.

There is also a GPIB-140A/2 extender that can extend the GPIB cable length up to 2 km while still maintaining the integrity of the GPIB and requiring no software modifications. Similar to the GPIB-140A, the device also uses buffered transmission technology, with data transfer rates up to 1.1 Mb/s (IEEE 488.1) or 2.8 Mb/5 (HS488). In addition, the GPIB-140A/2 increases the maximum number of GPIB devices in the system from 15 to 26.

The GPIB-140A extender uses optical cable to extend the length of the GPIB system. To connect the system to a high-speed GPIB extender device, a fiber optic cable with a GPIB extender can be used to extend the cable length of the system without compromising the integrity of the GPIB device or altering any applications. The GPIB T7 model with GPIB 140A extenders can extend the system up to 1 km, while the GPIB type T8 with a pair of GPIB 140A/2 extenders can extend the system up to 2 km.

The NI GPIB-140A/2 extender can be used in various industries such as electronic test and instrumentation, desktop measurement and testing, distributed measurement and control, and systems engineering software.

1 km, GPIB Bus extender - The GPIB-140A extends the cable of the GPIB system by one kilometer without compromising the integrity of the GPIB and without software modification. The accessory uses buffered transmission technology with data transfer rates up to 1.1Mb/s (IEEE 488.1) or 2.8Mb/s (HS488). The GPIB-140A can also increase the maximum number of GPIB devices in a GPIB system from 15 to 26.

This nickel GPIB-140A(part number :777997-01,777997-02,777997-03,777997-04,777997-05, and 777997-06) is a GPIB bus extender. This device easily eliminates the limitations related to cable length and device load imposed by the IE488 standard. The GPIB-140A is fully compatible with IEE488.1 and EEE 488.2 standards. According to the IEEE 488 standard, the total length of any GPIB system cannot exceed 20 meters. The GPIB extender can reach a total distance of 1 kilometer without any modification and without affecting the integrity of the user's GPIB system.

The GPIB extender can support up to 1 km of cable. This nickel GPIB-140A comes with a slow-medium transfer technology that makes this model the fastest GPIB bus extender available. With this model, users can achieve speeds of more than 2.8 megabytes while working under the HS488 protocol. This GPIB extender can be easily deployed with no additional hardware required. In typical cases, one end of the computer device is connected to a cable expander. At the far end, the GPIB instrument is connected to a similar cable extension. The two cable extenders are then connected via optical cable.

Each nickel GPIB-140A continuously monitors GPIB activity and converts GPIB signals into parallel or serial signals for transmission to the receive extender. The receiving extender receives a serial or parallel signal from the sending extender and converts it into an IEEE488 signal. This nickel GPIB-140A does not require modification of existing software applications as it is software transparent.
