   That looks like the same contact I started with. I'll start by asking   
   about remote control using a computer. Kinda doubt it'll go anywhere,   
   but at this stage there's little to lose. If it ends up looping back   
   to the same support rep at least the question is new.   
      
   Thanks for the good luck wish, I'll need it.

   There has been considerable interest and effort to understand communications   
   protocols for other devices, but it may be hard to find. Sourceforge, github   
   and sigrok are good places to look. The most useful program I found to   
   communicate with a multimeter was in German, which fortunately I studied in   
   college and practiced when I was stationed there. Instead of numerical   
   values the meter transmits the 7-segment LCD driver output which a Select   
   Case can easily decode back to digits.   
      
   For example:   
   https://sigrok.org/wiki/RDTech_UM_series   
      
   Those USB power meters are quite handy to show how (or if) devices charge. I   
   added external wires and PP45 connectors to one that measures up to 30V and   
   5A, making it a USB power to everything else adapter for solar charging and   
   cable resistance and load testing.
