f. Please insert terminal board into terminal block, then will be clamped automatically.
c. Insert the cable through the cap nut for each port. COM2(RS485 IN) COM3(RS485 OUT).
d. Pull down the terminal block on user interface board(See Figure 4.5).
e. Firstly insert cable into terminal board, then tighten the screws (dotted area) clockwise
with slotted screwdriver; if user need to pull out cable, screws rotates anticlockwise with
slotted screwdriver(See Figure 4.5).

Use the RJ45 connectors to perform the Ethernet communication which supports the
Canadian Solar Monitoring Platform and Modbus TCP protocol(Both By Default).
NOTE:
When creating daisy chain for Ethernet communication,
all inverters' slave
address must be set to 01.
CAT 5E outdoor rated (cable outer diameter<9mm, internal resistance≤1.5Ω/10m) and
shielded RJ45 connectors are recommended.
If the product is connected to a local network through a router, the product will be assigned
an IP address automatically, by the DHCP server.
Daisy chain is required for multiple inverter communication through ethernet as shown below.
Address: 01
Address: 01
Address: 01
NOTE:
Laptop is required for onsite Ethernet communication commissioning.
If the router doesn't support automatic IP address, use an Ethernet cable to
connect the module and your laptop.
Change the Laptop's IP address as
10.10.100.253 and then Use the web browser to enter 10.10.100.254 and
define your own IP address as in Figure 4.8.
Recommended web browser: Internet Explorer or Chrome.
