In order to use the Balloon Competition Logger you must install a driver.

• Please download the latest Prolific driver from Flytec.
• Install the driver
• Connect the device
• The driver allocates a COM port for the logger. Use your system tools (e.g. Device Manager) to find the port number that was chosen.

Please note that some privately owned loggers may not work with Windows 8.1 and need an upgrade from Flytec. Read this post for more details.
