All of Deuteron’s loggers and stimulation devices are controlled by the same program, called LoggerCommand3.EXE. The previous version was called LoggerDemo.EXE. When you purchase a Deuteron device, you will be given instructions on how to download and install this program. Presently, this program cannot be downloaded from the web site. If you want to update your version, please write to us and we will check if you also need to update embedded software before giving you further instructions.
