Your communication software usually overrides the parameters set by Windows Device Manager. There is a set of parameters that needs to be configured for the communication – baud rate, parity, number of data bits, stop bits, flow control, etc. Read more information about RS-232 Troubleshooting Configure serial communication parameters The two major cable types are ‘modem cables’ and ‘null modem cables’, the difference between the two is that in the former the wires go straight through, while in the latter they are crossed. If you don’t have additional wires, you won’t be able to communicate with device. for ‘hardware handshaking’ ( RTS/CTS or DTR/DSR data flow). Some devices might require additional lines for controlling the data flow, e.g. A typical cable would have at least three wires – transmit and receive lines and signal ground. The cables you use to connect to the port also matter. If in doubt launch Device Manager and check ‘Ports (COM & LPT)’ section, it should display a list of ports installed in the system including virtual ports, if you’ve got any. If your computer is equipped with several COM ports, make sure to choose the correct one. Serial Debugger (aka Serial Port Monitor) is a high-quality COM port debug utility that can log, display and help you analyze serial port communication in the system. to detect and solve issues at an early stage, it is important to view the data stream, and this is possible with the help of special software – Serial Port Debug software by Electronic Team. To successfully debug serial interface, i.e. In this article, we will discuss in details the most important aspects of serial port debugging. You have to take into consideration a number of aspects such as hardware and cabling, communication settings and protocols – any mismatch here can cause a problem. They include most of the equipment used in laboratories, quality and process controllers, various sensors, measuring instruments such as scales and a lot more.ĭespite the standard being so popular, it is not easy to debug RS232 connections. Devices that require RS232 interface for serial port communication are plenty.
