ECU INITIALIZATION SEQUENCE
Once power is supplied to the ECU it automatically steps through a series
of initialization screens on its LED display.
ECU INITIALIZATION
1. Loading the software rmware.
2. Searching for the inverters.
A word about network communication protocols. The ECU needs to have
access to the router via an IP address. The ECU will only search for and
obtain a DHCP IP address during its powering up sequence.
For example, the LED screen on the front of the ECU displays an
IP address such as “192.168.2.101” if the connection to the router is
successful (the IP address will vary based on router supplier, so check
with the user manual for specics). If, however, the LED displays
“60.190.131.228”, the ECU-router connection has not been successful, in
which case you’ll need to check all of the cabling connections and reboot
the ECU by removing the power cable for a few seconds and reconnecting.
