NI PXIe-7962R端口隔离器可在单点或多点模式下运行，由模块顶部的滑动开关选择。端口隔离器提供以下功能：•四个光隔离信号通道：SD、RD、RTS和CTS•与RS-485的电气兼容性•单点或多点操作•符合串行通道标准的输入端接•用于电源隔离的5V DC/DC转换器•支持热插入连接器隔离器提供两个连接器，一个15针公D型（PL1）和一个15引脚母D型（PLL2）。如果端口隔离器用于端口对端口模式或多点配置的末端，则使用端接电阻器。要终止RD平衡线，请在针脚9和针脚10之间放置一根跨接导线。a表示–，B表示+。NI PXIe-7962RA和B表示输出，A’和B’表示输入。安装隔离器封装在轮廓塑料外壳中，该外壳设计用于直接连接到串行端口，或通过12“延长电缆用于面板安装应用NI PXIe-7962R
The Port Isolator can operate in either single- or multi-drop mode, which is selected by a slide switch on the top of the module. The Port Isolator provides the following features: • Four opto-isolated signal channels: SD, RD, RTS, and CTSNI PXIe-7962R• Electrical compatibility with RS-485 • Single- or multi-drop operation • Input termination consistent with standard for serial channels • A 5V DC/DC converter for power isolationNI PXIe-7962R• Hot insertion is supported Connectors The Isolator provides two connectors, one 15 pin male D-type (PL1) and one 15 pin female D-type (PL2).Use the terminating resistor if the Port Isolator is used in port-to-port mode or at the end of a multi-drop configuration. To terminate the RD balanced line, place a jumper wire from pin 9 to pin 10.A denotes – and B denotes +. A and B denote outputs and A' and B' denote inputs.Installation The Isolator is packaged in a contoured plastic enclosure designed for either direct attachment to a serial port or through a 12” extender cable for panel mounted applicationsNI PXIe-7962R
