Serial Port Splitter: Connect Multiple Devices to One COM Port
Have you ever tried to connect two devices to one serial port? Usually, Windows will block you. It gives you an error because only one program can use a COM port at a time.
A serial port splitter fixes this problem. It lets multiple apps or devices share a single COM port at the same time. How a Serial Port Splitter Works
A serial port splitter is a special software tool. It takes one physical COM port and creates many virtual copies of it.
The Main Port: Your real device plugs into the physical COM port.
The Virtual Ports: The software creates exact digital clones of that port. The Connection: Your apps connect to the virtual ports.
The software passes data back and forth between the real port and the virtual clones. Every connected app thinks it has exclusive access to the real device. Common Ways to Use a Splitter
People use serial splitters in many industries to save money and space.
GPS Data: Send one GPS signal to both a map app and a tracking app.
Weather Stations: Share weather data with multiple display screens.
Factory Machines: Allow monitoring tools and control tools to read the same machine.
Laboratory Gear: Let multiple computers log data from one science tool. Key Features to Look For
