2.3 Configuring the Relay Serial Data Communication

2.3 Configuring the Relay Serial Data Communication
You can configure the 7SR45 Argus relay by using the keys on the relay fascia. Scroll down from the SETTING
MODE and navigate to the COMMUNICATION menu and change the settings for the communication port if
needed.
Reydisp Evolution uses the IEC 60870-5-103 protocol to communicate.
When connecting the relay to a PC using the front USB port, the Reydisp Evolution automatically detects the
relay. If the USB-Protocol selected is IEC60870-5-103, then setting changes are not required.
