AR100 Operation Manual

Binary Parameters:
0Ah
–
Low byte for maximum integration time.
0Bh
–
High byte for maximum integration time.
ASCII Command:
Exxxx
–
Where
xxxx
is the maximum integration time.
Value ranges:
2 to 3200. This value specifies the limiting integration time for the CMOS array
in increments of 1
μ
s.
The measurement frequency depends on the integration time of the receiving
array. Maximum frequency (9.
4 kHz) is achieved for the integration time ≤106
μs (minimum possible integration time is 0
.
1 μs). As the integration time
exceeds 106
μs, the resulting update time increases proportionally.
Increasing this parameter
may improve the sensor’s ability to measure to low
-
reflecting targets at the cost of decreased speed and possible increased effects
of ambient light on measurement accuracy. Decreasing
the parameter’s value
increases measurement frequency, but may decrease measurement accuracy.
8.8
Results Lock (Binary: 10h; ASCII: Dxxx)
Default Value:
1
–
5ms
If the sensor does not
“see” the target surface or if a new measurement cannot
be received, a zero value is transferred. The Results Lock parameter sets a
time limit during which the sensor transfers the last valid result instead of a
zero value. The factory default value is 5 ms.
The binary parameter (
10h
) and the ASCII command (
Dxxxx
) both use a
value range of 0 to 255 . It specifies the time interval in increments of 5 ms.
8.9
Results Averaging Mode (Binary: 02h bit A; ASCII: TMx)
Default Value:
0
–
Averaging over a Number of Results
This parameter defines one of the two methods of averaging of measurement
results implemented directly in the sensor: Averaging over a Number of
Results or Time Averaging. The factory default setting is for Averaging over a
Number of Results.
The binary parameter (
02h bit A
) and the ASCII command (
TMx
) both use
two values, 0 or 1, representing one of two modes:
Averaging over a Number of Results
–
Value: 0
–
When selected, a
sliding average is calculated and transmitted to the sensor’s outputs
Time averaging
–
Value: 1
–
When selected, the measurement results
are averaged over a time interval
