ASCII
ASCII characters packed 2 per register in high, low order and without any termination characters.
SINT32 / UINT32
FLOAT
32-bit signed / unsigned integer spanning 2 registers. The lower-addressed register is the high order half.
SINT16 / UINT16
16-bit signed / unsigned integer.
End of Map
32-bit IEEE floating point number spanning 2 registers. The lower-addressed register is the high order half (i.e., contains the exponent).
All registers not explicitly listed in the table read as 0. Writes to these registers will be accepted but won't actually change the register (since it doesn't exist).
Meter Data Section items read as 0 until first readings are available or if the meter is not in operating mode. Writes to these registers will be accepted but won't actually change the register.
Register valid only in programmable settings update mode. In other modes these registers read as 0 and return an illegal data address exception if a write is attempted.
Meter command registers always read as 0. They may be written only when the meter is in a suitable mode. The registers return an illegal data address exception if a write is attempted in an incorrect
mode.
If the password is incorrect, a valid response is returned but the command is not executed. Use 5555 for the password if passwords are disabled in the programmable settings.

CT = numerator * multiplier / denominator
