2.產(chǎn) 品 詳 情 資 料：
NI PXIe-5450矢量調(diào)制器連接器上的信號可用，但RS-422規(guī)范中不包括這些信號。SD（發(fā)送數(shù)據(jù)）和RD（接收數(shù)據(jù)）與TXD和RXD（用于六系列PLC）相同。（A） 和（B）與-和+相同。A和B表示輸出，A’和B’表示輸入。接收數(shù)據(jù)（RD）信號的終端電阻只需連接在線路末端的單元上。NI PXIe-5450通過在5引腳D外殼內(nèi)的引腳9和0之間連接跳線，可在90系列PLC產(chǎn)品上實現(xiàn)此端接，但以下情況除外：對于目錄號為IC697CPU73 J和IC697CPU77 G的90-70系列PLC以及更早版本，PLC上的RD端接通過引腳9和之間的跳線實現(xiàn)。Workmaster串行端口Workmaster II工業(yè)計算機，RS-232串行端口是25針D型公連接器，早期型號Workmaster是9針公連接器。圖A-2顯示了兩個com的串行端口連接器布局NI PXIe-5450
Signals available at the Connector but are not included in the RS-422 specification. SD (Send Data) and RD (Receive Data) are the same as TXD and RXD (used in the Series Six PLC). (A) and (B) are the same as - and +. A and B denote outputs, and A’ and B’ denote inputs.Termination resistance for the Receive Data (RD) signal needs to be connected only on units at the end of the lines. This termination is made on the Series 90 PLC products by connecting a jumper between pins 9 and NI PXIe-5450 inside the NI PXIe-5450-pin D-shell with the following exception For Series 90-70 PLCs with Catalog Numbers IC697CPU73NI PXIe-5450 and IC697CPU77NI PXIe-5450 and earlier the termination for RD at the PLC is implemented by a jumper between pins 9 and NI PXIe-5450.Workmaster Serial Port The Workmaster II industrial computer, RS-232 serial port is a 25-pin D-type male connector, and the early model Workmaster is a 9-pin male connector. Figure A-2 shows the serial port connector layout for both com
