Serialport-bridge Software

Serialport-bridge Software

Serialport-bridge is a computer program which gives javascript applications running in your web browser the ability to access and control USB/Serial devices connected to your computer. This software was developed by IO Rodeo in order to enable the distribution of application software as simple web pages. Before you can run one of IO Rodeo's web pages based programs you will need to download and install the Serialport-bridge program.

Downloading and installing pre-compiled binaries

The easiest way to get the serialport-bridge software is to download and install a pre-compiled binary for your OS.

MS Windows

There are two binary versions of serialport-bridge available for MS Windows - an NSIS installer and a stand alone binary. The NSIS installer is a typical windows installation program which will place the serialport-bridge application in your computer's "Programs Menu", add (optional) short cuts on your computer's Desktop, etc. The stand-alone binary version, on the other hand, requires no installation. In this case you download a single .exe file which you simply double click to run the application.

The serialport-bridge NSIS installer for windows can be downloaded from here:

  • After downloading, double click on the installer application to begin the installation process.
  • Depending on your computer's settings, after starting the installer, you may see a screen saying "Publisher could not be verified. Are you sure you want to run this software?" If you wish to continue select the"Run" option to continue with the installation.
  • When the installer is running you should see a screen like the one shown in the image below. Answer the questions and follow the instructions given by the installer to complete the installation process.

Using the Serialport-bridge Program

The Serialport-bridge program primarily runs in the backgroud and provides a "bridge" so that javascript applications running in your web browser can access and control the USB/Serial port on your computer. In general there isn't much more to do once the Serialport-bridge program has been started. Leave it running in the background as long as you want to enable web page application to access your computer's USB/Serial ports. It does however provide useful information on several tabs which can be helpful for setup and diagnostics.

The Bridge Server Tab

The Bridge Server tab (shown below) provides information about the serialport bridge server.

  • Version: the version number of the Serialport-bridge program
  • Clients: a list of all the clients connected to the Serialport-bridge server. A client is just an external program which is making use of the Serialport-bridge to access the USB/Serial. This list will always contain at least one client - the Serialport-bridge program itself.
