However, it works fine with the Wi-Fi dongle.Can anyone help me?You have to use the supplied RJ-45 to RS-232 cable. If you somehow don't have it, the pinout is here. The RJ-45 connector is NOT an ethernet port.Most PCs will require a USB to RS-232 adapter. See for example the discussion in the firmware upload instructions,The serial ports operate at 2400 bps. The protocols are documented in various protocol manuals, e.g. this old one. But most people will want to use a program to automatically send and receive those commands, e.g. WatchPower, SolPipLog, etc.The above is all assuming that your EASun is an Axpert made by Voltronic. If it's an early EASun that was a clone, then all bets are off.
