Please note that due to big vs.- little endian bytes are swapped,
should be read as:
00: 67ff 00ca 5da2 03c8 0650 8000 7f81 ff00
08: 0000 0000  

corresponding sensor values are about (not read at same time):
in0:           1.99 V  
in1:          23.97 V  
power1:        6.10 W  
curr1:       248.00 mA 

in0 should be read as mV
