USB Interface
The USB interface can be used to establish a connection between the protection device and your PC. For the
communication, the Microsoft Windows USB driver is used which is installed together with DIGSI (as of version
V4.82). The interface is installed as a virtual serial COM port. We recommend the use of standard USB cables
with a maximum length of 5 m/16 ft.
