Hello, > Can you explain what is exactly a plus-box ? The voyager 44 or 84 is a usb brailledisplay.. With tThe plus-box you can use the voyager under plain dos in combibraille-mode. If you use windows or linux you can switch to usb and voyager modus or to combibraille/ (multibraille for 84-modell) on an serialport.
