RS232 Splitter
Split RS232 ports among several apps

RS232 Splitter is a tool that allows simultaneous access to a serial port by several applications. Based on a single hardware port it creates multiple virtual serial ports thus enabling all applications connected to the port receive the same data at the same time. Virtual serial ports are no different from the real port. Also, with RS232 port splitter you can join several ports into a single one, combine them in bundles of any complexity and divert data flow from one port to another.

The newest release of RS232 data splitter offers switcher functionality, i.e. the software can automatically detect which of the specified ports is free and assign it to an application. It is also capable of recording events in logs, this enables you to track the usage of ports by various applications.

Functionality offered by RS232 Splitter

  • Split a single port into many

    RS232 Splitter creates multiple virtual serial ports linked to a single hardware port, thus a single RS232 port can be divided into a virtual port 1, 2, 3…, N. Virtual ports are created with parameters identical to those of a hardware port, so the system does not see any difference between them.

    Serial RS232 port splitters allow providing simultaneous access to a serial device inserted in a real port to several applications. The hardware port does not need to be split into multiple virtual ports.
  • Join multiple ports into one

    RS232 Splitter is capable of connecting any number of ports into one. It means that data sent by multiple devices will be directed to a single port, i.e. the port at the OUT end of the bundle.
  • Create a bundle of ports

    RS232 Splitter provides charts that help you create bundles of RS232 ports. It is possible to connect real and virtual serial ports in any direction – incoming, as well as outgoing. Each of the sides – IN and OUT – can have the Main port for managing control lines of the serial ports.
  • Switch ports

    RS232 Splitter has switcher functionality, i.e. it is capable of automatically detecting a free port in the list of specified serial ports and assigning it to an application that requires it. This is especially handy for applications that can interact with a limited number of ports. Multiple ports can be given the same name, so it appears as if you are working with the same port all the time.
