National Instruments GPIB-RS485 GPIB 仪器控制装置

NI GPIB-RS485（部件号：779733-11、779733-01、779733-04、779733-12和779733-02）是一款GPIB仪器控制设备。 该设备专为具有工作串行端口的计算机而设计：RS485 或 RS422。NI GPIB-RS485 能够 将 用户 的 计算机 转换 为 控制器 和 监听 器。此外，GPIB RS485 还可以将 RS422 和 RS485 外设和仪器与 GPIB（通用接口总线）对齐。

使用此模型，用户可以实现并满足 IEEE RS422、RS485 和 RS488 标准的电气和物理规范。此外，这款IEEE 488兼容器件还可以实现GPIB到串行和串行到GPIB的协议转换和高级命令执行。National Instruments GPIB-RS485 与 National Instruments NI-488.2 驱动程序配合使用。因此，用户在通过GPIB连接到第三方设备和仪器时可以享受最大的可靠性。

该控制器和转换器设备配有一个标准的 24 针 GPIB 连接器、一个 DB-9 公头 RS232 连接器和一个 DB-9 公头 RS485/RS422 连接器。为了接收直流电源以运行，设备背面还提供了一个同轴插头。对于 GPIB 通信， NI GPIB-RS485 使用 3 线 信号。但是，在 RS232 和 RS485 串行通信中，用户可以实现高达 115.2 kb/s 的波特率。

该 GPIB 仪器控制设备提供 12 VDC 电源，可在 100 至 240 VAC（47 至 63 Hz）的输入电压范围内工作，并输出 12 VDC，仪器最大 1.25 安培。在 12 VDC 时，National Instruments GPIB-RS485 消耗 300 mA。

【英文介绍】

National Instruments GPIB-RS485 GPIB instrument control unit

The NI GPIB-RS485 (Part number: 779733-11, 779733-01, 779733-04, 779733-12 and 779733-02) is a GPIB instrument control device. The device is designed for computers with working serial ports: RS485 or RS422. The NI GPIB-RS485 converts the user's computer into a controller and a listener. In addition, GPIB RS485 can also align RS422 and RS485 peripherals and instruments with GPIB (Universal Interface Bus).

Using this model, users can implement and meet the electrical and physical specifications of the IEEE RS422, RS485, and RS488 standards. In addition, this IEEE 488-compatible device enables GPIB to serial and serial to GPIB protocol conversion and advanced command execution. The National Instruments GPIB-RS485 works with the National Instruments NI-488.2 driver. As a result, users enjoy maximum reliability when connecting to third-party devices and instruments via GPIB.

The controller and converter unit comes with a standard 24-pin GPIB connector, a DB-9 male RS232 connector, and a DB-9 male RS485/RS422 connector. To receive DC power for operation, a coaxial plug is also provided on the back of the device. For GPIB communication, NI GPIB-RS485 uses a 3-wire signal. However, in RS232 and RS485 serial communication, users can achieve baud rates of up to 115.2 kb/s.

The GPIB instrument control unit provides 12 VDC power, operates in an input voltage range of 100 to 240 VAC (47 to 63 Hz), and outputs 12 VDC with an instrument maximum of 1.25 amps. At 12 VDC, National Instruments GPIB-RS485 consumes 300 mA.
