Accelerated rangefinder Product manual
A summary of the settings available through the USB port is given in the table below:
Setting Values Description
1: Active data port Serial <-> USB Selects the serial or USB port to output distance data.
2: Snapshot resolution /
Time series filter
1.00 m ... 0.03 m <->
filter active
Selects the resolution of each reading taken. When selected, the
“Time series filter” changes the result from a single snapshot to
a recursive Kalman filter output.
3: Serial port
update rate
@ 1.00 m 1 ... 36633 / sec Sets the rate at which new results are output from the serial
port when it is selected using “1. Active data port”.
The actual value may be lower than the entered value depending
on the setting “2: Snapshot resolution”.
Only whole number fractions of 36633 will give an exact match
between the entered and actual values.
@ 0.50 m 1 ... 18316 / sec
@ 0.25 m 1 ... 9158 / sec
@ 0.03 m 1 ... 1144 / sec
@ Filter 1 ... 1144 / sec
4: Serial port baud rate 9600 ... 921600
Selects the baud rate for the serial port. If the “3. Serial port
update rate” setting is too high for the selected baud rate then a
warning notice will be displayed.
5. Analog port
update rate
@ 1.00 m 1 ... 36633 / sec Sets the rate at which the analog port and the alarm signal are
updated with distance readings.
The actual value may be lower than the entered value depending
on the setting “2: Snapshot resolution”.
Only whole number fractions of 36633 will give an exact match
between the entered and actual values.
@ 0.50 m 1 ... 18316 / sec
@ 0.25 m 1 ... 9158 / sec
@ 0.03 m 1 ... 1144 / sec
@Filter 1 ... 1144 / sec
6: Analog maximum range
256 m <-> 128 m <->
64 m <-> 32 <->
16 m <-> 8 m
Selects the maximum distance that produces 2.56 V on the
analog port. This value changes the scale of the analog output.
7: Alarm activation distance 0.5 m ... 254 m
Sets the distance below which the alarm signal will change to a
low state. There is hysteresis on this setting equal to the “2:
Snapshot resolution” setting or 0.06 m whichever is the greater
value.
8: Alarm latch Off <-> Active
Enables the alarm signal latch. This keeps the alarm in the active
low state after an alarm event until it is cleared by sending the
“#X” command to the serial port, or by pressing <X> on the
keyboard.
9: USB port update rate 1 ... 1144 / sec
Sets the rate at which new results are output from the USB port
when it is selected using “1. Active data port”.
The maximum value is limited to 1144 readings per second.
Only whole number fractions of 36633 will give an exact match
between the entered and actual values.
