To operate the CMI, a 12 V supply from either the CAN bus or a 12 V power supply unit (not available with CMI-S) is required. Power is not supplied via DL bus.
Power consumption: typically 1.5 W
If there is only one controller (UVR1611, UVR16x2, RSM610) in the network, it is essential to use a 12 V power supply unit to ensure power to other CAN bus subscribers that do not have their own supply.
Data retention is also ensured without power supply.
