6mmm/s does not need the fancy LCD and can be operated without it.
No matter if the display is attached or not, the unit always transmits the following data via its serial TX line, at 9600 bits/s, 8N1:

   ---
    v = <speed> m/s
    m = <mass> g
    E = <energy> J
		

Same with invisible codes included:

   <CR><LF>---<CR><LF>
    v = <speed> m/s<CR><LF>
    m = <mass> g<CR><LF>
    E = <energy> J<CR><LF>
		

with the known substitutions:

   <CR> = 0x0D (13 decimal)
   <LF> = 0x0A (10 decimal)
		

Data reception ("RX") is not (yet) built in (and probably never will be in there).
It's not required. The receiving equipment needs nothing else but the velocity and should calculate the energy by its own...
