czy nowe oprogramowanie należy instalować przez port instalować poprzez port USB2 czy RS485 ?. W instrukcji obsługi połaczenie z laptopem powinno być portem USB2, natomiast port RS485 służy do komunikacji z BMS batrii. Otrzymałem od państwa oprogramowanie + narzędzię do instalacji pod port RS4685 i podczas próby instalacji zgłasza blokadę transferu pliku, zatem mogę tego oprogramowania użyć przez port USB2 ?
