When SMVRCV is connected to ULTVTR2 in the Application Configuration tool, ULTVTR2 is disconnected from the physical channel U_SYN and uses UL1 voltage from the received IEC 61850-9-2 LE sample value. All functions which have U_SYN input begin working with the IEC 61850-9-2 LE sample value.

Note: Only UL1 must be connected between SMVRCV and ULTVTR2 in the Application Configuration tool.
Note: The IEC 61850-9-2 LE stream always contains UL1, UL2, UL3 and Uo. When U_SYN as a single channel input is received from IEC 61850-9-2 LE, the setting VT connection in Configuration > Analog inputs > Voltage (3UB,VT)// must be “UL1”.
