6.3.3 Basic Measurement Parameters
6.3.3.1 Enabling the Desired Data Outputs for Results
Command Reply Range
Meaning
ROn<Cr>
*ROn
0
≤
n
≤
255 Enabling the
output of measurement
results
for different outputs: The bits of the
value have the following meaning:
bit 0: Serial interface output
bit 3: ECP data output
Example: RO8 sets ECP output only, RO9
sets ECP + serial output
In scanning mode enable the ECP data output only, therefore set to RO8 !
Note that the command effects the
output of measurement results only
.
Therefore e.g. errors are still reported on the serial output, even when the
corresponding data output bit 0 in RO is cleared. Similarly the serial
programming mode is not effected by the setting for the serial data output in
RO.
6.3.3.2 Selective Measurement of Strong Reflector Targets (Setting an
Amplitude Window)
Command Reply Range
Meaning
ALn<Cr>
*ALn
0
≤
n
≤
255 Setting the minimum value of signal
amplitude values accepted
AHn<Cr>
*AHn
0
≤
n
≤
255 Setting the maximum value of signal
amplitude values accepted
These feature allows to set an signal amplitude window to measure targets with
a reflectivity in a certain range. E.g. to measure only targets equipped with
reflectors and to make it insensitive for diffusely reflecting targets, set AL to a
value of approx. 80 and AH to 255.
