NI GPIB-140A 总线扩展器 1千米GPIB总线扩展器——GPI b-140 a可以将GPIB系统的电缆长度扩展到1千米,而不会影响GPIB的完整性,也不需要修改软件。该配件使用缓冲传输技术,以高达1.1 Mb/s (IEEE 488.1)或2.8 Mb/s (HS488)的速率传输数据。GPIB-140A还将GPIB系统中GPIB设备的最大数量从15个扩展到26个。
GPIB-140A(零件号:777997-01,777997-02,777997-03,777997-04,777997-05,以及777997-06)是一个GPB总线扩展器。这种设备很容易消除IEEE 488标准强制要求的电缆长度和设备负载相关的限制。这GPIB-140A完全兼容IEEE 488.1和lEEE488.2标准,根据IEEE 488标准,任何GPIB系统的总长度都不能超过20米GPIB扩展器可以达到1公里的总距离,而无需任何修改,也不会影响用户的GPIB系统的完整性
这GPIB扩展器可支持长达1公里的光缆。这镍GPIB-140A附带一个缓冲传输技术,使这个模型成为最快的GPIB总线扩展器可用。利用这一模型,用户在HS488协议下工作时可以实现2.8兆字节以上的速度。这GPIB扩展器可以轻松部署,不需要额外的硬件。在典型情况下,计算机设备的一端连接到电缆扩展器。在远端,GPIB仪器连接到一个类似的电缆延长线上。然后,两个电缆延伸器通过光缆互连。
每个镍GPIB-140A持续监控GPIB活动,并将GPIB信号转换为并行或串行信号,以传输到接收扩展器。接收扩展器从发送扩展器接收串行或并行信号,并将其转换为IEEE 488信号。这镍GPIB-140A不需要修改现有的软件应用程序,因为它是软件透明的。

NI GPIB-140A bus expander 1 km GPIB bus expander-GPIB-140a can extend the cable length of GPIB system to 1 km without affecting the integrity of GPIB and without modifying the software. The accessory uses buffered transmission technology to transmit data at a rate as high as 1.1 Mb/s (IEEE 488.1) or 2.8 Mb/s (HS488). GPIB-140A also extends the maximum number of GPIB devices in GPIB system from 15 to 26.
GPIB-140A (part numbers: 777997-01, 777997-02, 777997-03, 777997-04, 777997-05, and 777997-06) is a GPB bus expander. This kind of equipment can easily eliminate the cable length and equipment load-related restrictions imposed by IEEE 488 standard. This GPIB-140A is fully compatible with IEEE 488.1 and lEEE488.2 standards. According to IEEE 488 standard, the total length of any GPIB system cannot exceed 20m, and the GPIB extender can reach a total distance of 1km, without any modification and without affecting the integrity of the user's GPIB system.
This GPIB extender can support optical cables up to 1 km long. This nickel GPIB-140A comes with a buffer transmission technology, which makes this model the fastest GPIB bus expander available. Using this model, users can achieve a speed of more than 2.8 megabytes when working under the HS488 protocol. This GPIB extender can be easily deployed without additional hardware. Typically, one end of a computer device is connected to a cable expander. At the far end, GPIB instruments are connected to a similar cable extension line. Then, the two cable extenders are interconnected by optical cables.
Each nickel GPIB-140A continuously monitors GPIB activities and converts GPIB signals into parallel or serial signals for transmission to the receiving expander. The receiving expander receives serial or parallel signals from the transmitting expander and converts them into IEEE 488 signals. This nickel GPIB-140A does not need to modify the existing software application, because it is software transparent.
