GPIB-130 总线 扩展 器 高速并联传输

【产品详情】

特征：

高速并联传输

将最大GPIB电缆长度延长至300 m

传输速度超过 900 KB/s

缓冲或无缓冲传输

NI GPIB-130 总线 扩展 器 消除了 IEEE 488 标准对电缆长度和设备负载的限制，同时几乎不需要桌面空间。IEEE 488 标准规定，GPIB 系统的电缆总长度不能超过 20 m，最大设备数为 15 个。NI GPIB-130 可通过 高速 并行 传输 将 距离 延长 至 300 m。

这些GPIB扩展器使用缓冲传输技术，以业界最快的速率传输数据，同时将布线成本保持在最低水平。每个扩展器都有一个错误检查方案，用于 确保链接无误。GPIB-130扩展器可以达到超过900 KB/s的速率。

NI GPIB-130（部件号：776526-01、776526-02、776526-03、776526-04、776526-05和776526-06）是一款GPIB总线扩展器。 该器件用于更改 IEEE 488 标准中定义的电缆长度和器件负载限制。在该标准中，用户在部署GPIB系统时不能超过20米。此外，在单个GPIB系统上可以使用的器件不超过15个。GPIB扩展器将GPIB消息转换为并行或串行信号，以连接到部署在接收器端的类似扩展器。因此，用户将需要两个类似的扩展器来构建扩展的GPIB网络。

使用 NI GPIB-130， 用户 可以 将 最大 电缆 距离 增加到 300 米， 而 GPIB 设备 的 数量 可以 扩展 到 28 个。该设备的典型应用包括（但不限于）远程控制打印机或绘图仪、隔离部署在危险或嘈杂环境中的设备，以及从远程位置控制测试。

NI GPIB-130 完全 兼容 IEEE 488.1 和 488.2 标准。该设备对系统是软件透明的。因此，用户无需修改其现有程序和硬件基础设施。GPIB 130可与三根传输电缆一起使用。对于 50 米到 300 米的距离，可以使用 CL2 级 T2 电缆。对于 50 米的距离，用户可以使用 T5 电缆，这是 T2 电缆的更便宜、更小、更轻的替代品。该型号采用专门设计的传输技术，使其能够以每秒超过 900 KB 的传输速率运行。

【英文介绍】

Features:

High-speed parallel transmission

Extend the maximum GPIB cable length to 300 m

Transfer speed over 900 KB/s

Buffered or unbuffered transmission

The NI GPIB-130 bus extender eliminates the limitations of the IEEE 488 standard on cable length and device load, while requiring almost no desktop space. According to the IEEE 488 standard, the total cable length of the GPIB system cannot exceed 20 m, and the maximum number of devices is 15. The NI GPIB-130 can extend the distance up to 300 m through high-speed parallel transmission.

These GPIB extenders use buffered transfer technology to transfer data at the industry's fastest rates while keeping cabling costs to a minimum. Each extender has an error checking scheme to ensure that links are correct. The GPIB-130 extender can reach speeds in excess of 900 KB/s.

The NI GPIB-130 (part number: 776526-01, 776526-02, 776526-03, 776526-04, 776526-05, and 776526-06) is a GPIB bus extender. This device is used to change the cable length and device load limits defined in the IEEE 488 standard. In this standard, users cannot exceed 20 meters when deploying GPIB systems. In addition, no more than 15 devices can be used on a single GPIB system. The GPIB extender converts GPIB messages into parallel or serial signals to connect to a similar extender deployed on the receiver side. As a result, users will need two similar extenders to build an extended GPIB network.

With the NI GPIB-130, users can increase the maximum cable distance to 300 meters, while the number of GPIB devices can be expanded to 28. Typical applications for this device include (but are not limited to) remotely controlling printers or plotters, isolating devices deployed in hazardous or noisy environments, and controlling tests from remote locations.

The NI GPIB-130 is fully compatible with IEEE 488.1 and 488.2 standards. The device is software transparent to the system. As a result, users do not need to modify their existing programs and hardware infrastructure. The GPIB 130 can be used with three transmission cables. For distances from 50 meters to 300 meters, CL2 class T2 cable can be used. For a distance of 50 meters, users can use the T5 cable, which is a cheaper, smaller and lighter alternative to the T2 cable. This model features a specially designed transmission technology that enables it to operate at a transfer rate of more than 900 kilobits per second.
