scale (5 characters) = Attenuated_SCALE parameter, %, 0 ... 99999. 100% is default

res (2 characters) = Backscatter profile resolution in metres.

n (4 characters) = Profile length 2048

energy (3 characters) = Laser pulse energy, %.

lt (3 characters including leading +/-) = Laser temperature, degrees C

ti (2 characters) = Total tilt angle, degrees

bl (4 characters) = Background light, millivolts at internal ADC input (0 ... 2500)

pulse (4 characters) = Pulse quantity x 1000 (0000-9999)

rate (2 characters) =
