4.2.2 Connection to multiple inverters
When EzLogger Pro is connected to multiple inverters, “hand-in-hand” connection method can be
used; each inverter has two multiplexed RS485 communication
ports
, and one RS485
port
of
the inverter is connected to one RS485
port
of the next inverter. Note that
port
A shall
correspond to
Port
A, and
Port
B shall correspond to
Port
B, and the number of inverters
connected to a single COM port shall not exceed 20.
4.3 Connection to the Environmental Monitor
and
Meter
When EzLogger Pro is connected to the environment monitor ,
meter
and other devices, COM4 port
shall be used.
Schematic diagram of COM4 port is as follows:
