If your load cell comes with stranded wire, connect it to 7 or 8 (GND connection terminals).
If you have subscribed to the option, connect your power supply to the terminal block as shown in the picture.

== Uplink data Frame format ==

The uplink payload contains multiple fields: <mask>: bit field on 1 byte indicating the presence of other fields. Bit 7 is always to 1 because the mask is never extended on next byte.

Some examples (in hexadecimal):

    “820119”: the frame indicates

== Downlink Frame format ==

The sensor configuration contains the following fields:

    <up_frame_mask>: the mask identifying the different fields present in uplink frames (possible values are described in “Uplink data Frame format” section)

The downlink frame has the following format:

<cmd>: 1 byte containing WRITE_CFG_CMD=0x02


== Power consumption ==


Power consumption calculator based on the number of measurements and transmissions.
