7. The analog voltage interface
The analog interface on the main connector produces a linear voltage of between 0.00 V and 2.56 V that is proportional to the
measured distance. A distance reading of zero meters always produces a 0 V output.

6: Analog maximum range
The "5: Analog port update rate" setting allows the output rate of the analog port to be set to any value within the limits imposed by
the snapshot resolution. Values will be rounded in order to give whole number divisors of 36633 and limited automatically if they are
too high for the resolution selected.
The "6: Analog maximum range" selection changes the value in meters that equates to 2.56 V. This can be either: 256 m, 128 m,
64 m, 32 m, 16 m or 8m depending upon the requirements of the application.

Values
1 ... 36633 / sec
Sets the rate at which the analog port and the alarm signal are
updated with distance readings.
1 ... 18316 / sec
The actual value may be lower than the entered value depending
1 ... 9158 / sec
on the setting "2: Snapshot resolution".
1 ... 1144 / sec
Only whole number fractions of 36633 will give an exact match
between the entered and actual values.
1 ... 1144 / sec
256 m <-> 128 m <->
Selects the maximum distance that produces 2.56 V on the analog
64 m <-> 32 <->
port. This value changes the scale of the analog output.
16 m <-> 8 m
