Remarks
Convert the data
value into signed 2's
complement and
divide with 10, which
gives the setpoint.
Ex: Signed 2's
complement of the
0xFFFFFC7C is equal
to –900.
–900/10=–90. So the
CA setpoint is –90C.
To get BOM combine
570,574,578 data.
Ex. 155DR0A01R
All the remaining are
spaces.
All the remaining are
spaces.
123456 would be
encoded as
0x01E240.
