120 120  On the device board there is a P2 connector for connecting an expansion communication module: BMS Wi-Fi, BMS GSM or BMS LANmodule. With these modules, user can configure device parameters using the ElectricDeviceMonitor software and transfer accumulated log files with the state of the battery system to a remote server.
