12.5 = Transducer id 1 data (Supply voltage)
V = Transducer id 1 units (V, Supply voltage)
1 = Transducer id for Supply voltage
U = Transducer id 2 type (voltage)
3.460 = Transducer id 2 data (3.5V reference voltage)
V = Transducer id 2 units (V, 3.5V reference voltage)
2 = Transducer id for 3.5V reference voltage
G = Transducer id 4 type (generic)
HEL/___ = Transducer id 4 data (info field)
Transducer id 4 units (none, null)
4 = Transducer id for generic field
* Checksum delimiter
2D = Two-character CRC for the response.
<cr><lf> = Response terminator
