NI PXI-6528简单多点配置此配置显示如何连接单个隔离中继器/转换器进行信号转换或更大距离，在复杂网络中使用中继器/转换器的规则当设计包括PLC和RS-422中继器/转换器（砖）的复杂多点网络时，以下规则适用：规则1：当使用砖作为中继器时，端口J2应始终指向主机设备NI PXI-6528，端口J应始终远离主机设备。位于砖块侧面的开关应始终处于中间位置（on）。端口J指向主机的唯一情况是当砖用作从机上的转换器（RS-232）时。开关处于正确位置（CTS）。NI PXI-6528
Simple Multidrop Configuration This configuration shows how to connect a single Isolated Repeater/Converter for signal conversion or greater distance.Complex Multidrop Configuration This configuration shows how to connect multiple Isolated Repeater/ConvertersNI PXI-6528 for signal conversion,NI PXI-6528 greater distance, and more drops.Rules for Using Repeater/Converters in Complex Networks When designing a complex multidrop network including PLCs and RS-422 repeater/converters (bricks), the following rules apply: Rule 1: When using a brick as a repeater, port J2 should always be directed toward the host device, and Port J should always be directed away from the host device. The switch located on the side of the brick should always be in the center position (ON). The only case in which Port J is directed toward the host is when the brick is used as a converter (RS-232) at the slave. The switch is in the right position (CTS).NI PXI-6528
