Enjoy your LokSound equipped engines even more by adding or changing sounds and fine-tuning performance using this unit with your home computer. Easy to use with no prior knowledge of programming needed, the unit can be used with any PC with an audio card and a Windows operating system. Just connect the programmer to your PC using the serial port or the USB adapter (included). Start the software then place a loco with a LokSound decoder on your programming track.
