Biddle-TLS / ModBus-RTU
The module is mounted directly in the remote or BEMS module and allows access to various parameters.
Alternatively for configuration there is serial console interface.

factory-reset
With firmware version 260 and above it's possible to reset the modules settings to factory defaults (see above).
Once the reset-condition is met, all LEDs will light up once per second. After 5 seconds the defaults will be set and the module restarts with the default settings.
condition on hardware 2.x.x
There are 3 pads located at the left lower side of the PCB. The most left (input) and the right pad (GND) should be connected.
condition on hardware 3.x.x
Short circuit the two pins labeled ADDR_2 at the left top side of the PCB.
