Cascading Connection
•
You are advised to connect fewer than 30 devices to each RS485 route.
•
The baud rate, communications protocol, and parity mode of all devices on the RS485
cascading link must be the same as those of the COM ports on the SmartLogger.
Connecting the MBUS Cable
4.4
•
Ensure that both the
solar inverter and
SmartLogger support
MBUS
communication.
•
If the SmartLogger is
connected to the
solar inverter
through an AC power
cable, no RS485
communications
cable needs to be
connected.
•
If the SmartLogger
communicates
through MBUS, a
miniature circuit
breaker (MCB) and a
knife fuse switch
need to be installed
to prevent device
damage in the case
of short circuits.
