I am making a custom connector that will carry several signals to a test board including RS-422 RX+/RX- and TX+/TX-. The strange thing is that I didn't find a standard pinout for the DB9 connector used for the RS-422! So I checked the manufacturer of the RS-422 PCI card in my PC and found their own pinout which means that my test board can only be interfaced to this RS-422 from this ...

Meets Screw-type industrial wireing standards Signal Ground over Terminal blocks supported Supports four wire RS422, RS485, and two wire RS485 modes Supports 3.5mm 5 pin terminal blocks Converts a DB9 male RS422/485 port to a 5 pin terminal block
该博客主要介绍串口RS232、RS422、RS485的DB9接法。先说明了DB9管脚芯点定义，针对RS232和RS422/485有所不同。还对比了三者在工作 ...
Power for the CONV485/DB9 operation is drawn from the RS-232 port DTR and RTS lines and can be used where the communi-cation cable is short. Optional external power of between 5.5VDC and 16VDC at 40mA is all that is required when commu-nicating with multiple devices or long distances. External power is connected via pin eight for voltage and pin five of ground of the RS-422 DB9 connector.
关于DB9接头上RS422的引脚定义，我在网上看到过至少6个版本。但是目前我手里的很多设备是按照同一个版本做的，现在我把常见版本的RS422在DB9上的接法推荐一下： UTEK宇泰的绝大多数产品采用这个标准。典型产品，UT…
