followed by unsigned 16-bit integers as binary byte pairs, big-endian (most significant byte first), the
number of byte pairs determined by the current
WLR
i.e number of byte pairs = [endWL] – [startWL] + 1

if the data is being transferred
to
the RS-7, the RS-7 will respond with “Ok”<CR><LF> after the final data
byte has been received.
In order to pack the spectral data into 16-bit integers, the data are first normalized such that the peak value is
set to maximum (0xFFFF), thus one is required to multiply each integer by the scale factor once the transfer is
complete in order to re-establish the proper absolute magnitude of the data.
