NI GPIB-140A 186135F-311 NI现场总线扩展器

这镍GPIB-140A(零件号:777997-01,777997-02,777997-03,777997-04,777997-05，以及777997-06)是一个GPIB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IEEE488.2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信号转换为并行或电行信号，以传输到接收扩展器。接收扩展器从发送扩展器接收电行或并行信号，并将其转换为IEEE 488信号。

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 IEEE 488 standard. The GPIB-140A is fully compatible with IEEE 488.1 and IEEE488.2 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 buffered 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 telegraphic signals for transmission to the receive expander. The receiving extender receives an electrical or parallel signal from the sending extender and converts it into an IEEE 488 signal.
