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.

Connections at port A

If the interface is used for communication with the device, the data connection is to be checked.

When using the port as input for one or two RTD boxes, you should check the interconnection according to one

of the connection examples A.3.
