Sign bit
†
When a negative number is stored in a numeric variable, the sign bit 1 is set in the MSB to indicate the negative value. The value is
stored in a numeric variable in a 2's complement format.
(8) Response message for input of waveform data using binary data
The waveform binary data is two-byte 65536 integer data from –32768 to 32767, as
shown below; and sent in the sequence of upper byte and lower byte.
