Soluzione Solare SunMeter ProWind and Smartlogger – Connection and Setting Manual
The SunMeter is a high technology electronic device primary designed to accurately measure the solar
radiation and make it available to the user in the best suitable way for its applications. It can be connected to the Huawei Smart Logger as well.
Prerequisites
- You have logged in to the WebUI as advanced user.
Procedure
- Connect the weather station communication bus in one of the RS485 empty communication port: COM(1-3) and power supply to DC IN 24V input
NOTE:
If Smartlogger connects to the power supply through the 12V input power port, this port can be used as the 12V output power port. If DC IN 24V input is used, you need to use external power supply to supply the weather station).
Balanced differential bus RS485 needs to be terminated , at the extremities of the bus, by a 100-120 Ω resistor (0,25 W) between RS485+/RS485- lines in order to avoid signal’s reflections. If Smart Logger is the device at one extremity, place the resistor into the supplied female connector. - Log in to the WebUI as admin (Smartlogger3000) or advanced user (Smartlogger1000A) > choose Settings tab > select Comm.
