How To Monitor Multiple COM Ports Simultaneously Without Losing Data?
When you are working with an embedded system, industrial device or serial based networks, it is sure that you are not dealing with one COM port, there is involvement of different ports. There can be PLC and sensors to enable the control units and modems. So, when there are such multiple ports, it is a challenge for us as to how to manage these activities without missing any crucial data.
In such circumstances, there is a need for a reliable and feature-rich serial port monitor. If you want to know how these port monitoring tools can help you monitor your data efficiently, then you are at the right place. In this article, we will discuss how to monitor multiple COM ports with the help of a serial port monitor.
Why is Multi-Port Monitoring Important?
Let’s take a situation in which you are testing a new industrial system. In this testing, one port is connected to a temperature sensor, another to the fan controller and a third to the user interface. So, while these components are working simultaneously, if something is not behaving properly then it is tough to understand which device is the culprit.
Thus, in such cases, serial monitoring plays a significant role because you can view all the serial communication simultaneously in one place, so it will be easy for you to track the error.
What to Look for in a Multi-Port Monitoring Tool?
If you really want to monitor multiple ports at the same time, then your system should support the following features.
- The tool must be able to handle multiple active sessions at the same time. Each COM port should be able to monitor in real-time without any requirement for you toggle between the ports.
- There must be timestamp synchronization which is very critical while analyzing the cause and effect between different ports. For instance, if one device sends a command and the other device has to respond then the timestamp must be able to line up precisely to track the flow of the system.
- You must choose a tool that is optimized to handle any high-speed data across several streams without lagging and dropping packets. You must look for the features such as buffer control, background logging and minimal system resource use.
- In addition to this, you must look for a centralized view of the data. Some software provide a tabbed interface and some provide all the data consolidated in a single view. So, you must opt for the latter because it makes it easier for you to spot patterns, diagnose issues, and compare communication side by side.
- While you manage your data, there is a huge volume of such data and thus it can be very overwhelming to deal with it effectively. So, in this case, you need to have a portal that will have filters that will help you focus on specific commands, addresses, and keywords. In addition to this, there must be triggers that will alert you about the predefined events that occur during the system check.
Monitoring a COM portal is a complicated process and therefore, you should adopt for a software that will help you to ease this system check and provide all the relevant data effectively.
