the start-up process, wait approximately 20 s.
Red LED is permanently on
• Verify no short-circuit of the M-Bus bus by measuring the voltage
over the M-Bus master. The voltage should be between 24-30
VDC.
Red LED is flashing, the unit can not be accessed via LAN
• Is the CMe3100 configured with static IP or dynamic IP (dynamic
