C. Set up Modbus via RS-485
To set up Modbus communication, connect your
cable from the RS-485 network to a 4-pin Phoenix
pin plug. Check the "A" "B" marks on the back of
the device to make sure the cables are connected
in the right order, and fasten the screws on the
Phoenix pin plug to secure the cables.
Run the cables through the opening on the plate,
and plug the 4-pin Phoenix pin plug into the
corresponding terminals on the back of the
device.
The default Modbus address is set as 1, and can be
changed later via the Kaiterra Configuration Tool.
