DiagRA® Flash Station is the flashing tool which lets you flash up to 10 control units on separate CAN or CAN FD vehicle buses. In the case of DoIP, the control devices can be operated together in a subnet or each control device in its own subnet. In a shared subnet, the control units are uniquely identified due to their Entity Identification EID. When using one subnet per control unit, unique identification is guaranteed via the EID or via the control unit’s IP address. You decide which of the connected control units should be flashed.
