USB–UART Communication Cable

USB–UART Communication Cable

Using Battery Management System (Tiny BMS) UART commands it is possible:

• setup all settings
• read back and monitor live data, events, statistics,
• UART communication interface is the main Battery Management System (Tiny BMS) communication, enabled by default
• USB-UART cable to Tiny BMS communication connector and Battery Insider automatically connects to BMS
• wakeup BMS from sleep mode and all other tasks that BMS are intended to do for PC and custom systems.

USB–UART Communication Cable for Battery Management System (Tiny BMS) includes a single multi-purpose UART interface. In combination with various converters, the interface is compatible with USB, Bluetooth and CAN communication interfaces. Various proprietary commands are available for quick and straightforward connection to a PC Battery Insider application when configuration, diagnostics, or maintenance is needed. Also the main MODBUS protocol commands are supported for rapid integration to existing industrial systems. For more information about communication protocols refer to Battery Management System (Tiny BMS) communication protocols documentation.

UART communication interface is the main Battery Management System (Tiny BMS) communication, enabled by default. Using Tiny BMS UART commands it is possible to setup all settings, read back and monitor live data, events, statistics, wakeup Battery Management System (Tiny BMS) from sleep mode and all other tasks that BMS are intended to do for PC and custom systems. If USB-UART cable is used for Battery Management System (Tiny BMS) connection to a Windows Battery Insider application, it is no need any external steps of configuration, just plug USB-UART cable to Battery Management System (Tiny BMS) communication connector and Battery Insider automatically connects to Battery Management System (Tiny BMS), even if BMS is in deep sleep mode. Tiny BMS USB-UART converter is based on genuine Silicon Labs CP2102 chipset.

All recent Windows operating systems already include the drivers and cable will work straight away. If there is a problem, it is possible to download a driver version that is confirmed as compatible with Battery Management System (Tiny BMS) from Enepaq web store. Alternatively, driver can be downloaded directly from Silicon Labs support website, just make sure to get v6.7.3 or newer if you are running Windows 7 or later OS. When cable is connected, it will appear as a virtual COM port and Battery Insider application will connect to it automatically. When USB- UART communication is not necessary, any other communication module or SOC-BAR LED indicator can be connected to BMS communication interface connector. Only one Battery Management System (Tiny BMS) communication extension module can be connected to Tiny BMS at the same moment.

Note: The USB-UART cable is not galvanically isolated. Take spacial care and give your full attention to avoid ground loops and potential damage to equipment. Alternatively, use USB isolator.
