wM-Bus radio transceiver, compatible with Maddalena radio modules and meters, as well as other wM-Bus devices. The transceiver has a USB-A connector and is used to send and receive data from PCs, smartphones or tablets.
The USB wM-Bus 868/169 radio device is an ISM band (868 or 169 MHz) transceiver designed to communicate with Maddalena ElecTo communication modules and meters using the wM-Bus communication protocol. It features a USB-A connector, which serves both as a power source and as a data interface for connection to a PC or tablet.
The compact 868 MHz version, equipped with an integrated antenna, is optimized for walk-by submetering applications, where compactness and portability are essential. Versions with an RF SMA connector, available in both 868 and 169 MHz, are designed for use with external antennas and are ideal for drive-by operations in the utility metering sector.
Communication is managed through a proprietary USB protocol and is compatible with Maddalena reading and configuration software on Windows and Android operating systems.
