n values
Selects the resolution of each reading taken.
0 = 0.25 m
1 = 0.12 m
For the value 0 to 3 the result is provided as a two byte snapshot.
2 = 0.06 m
3 = 0.03 m
For a value of 4, the "Smoothing filter" changes the results to a recursive digital
filter output.
1 ... 18316
Sets the rate at which new results are output from the serial port.
1 ... 9158
The actual value may be lower than the entered value depending on the setting
1 ... 4579 "#Rn:" resolution.
1 ... 2289
Only whole number fractions of 18316 will give an exact match between the
entered and actual values.
1 ... 2289
1 ... 18316
Sets the rate at which the analog port and the alarm signal are updated with
distance readings.
1 ... 9158
The actual value may be lower than the entered value depending on the setting
1 ... 4579
"#Rn:" resolution.
1 ... 2289
Only whole number fractions of 18316 will give an exact match between the
entered and actual values.
1 ... 2289
0 = 256 m
1 = 128 m
2 = 64 m Selects the maximum distance that produces 2.56 V on the analog port. This value
3 = 32 m changes the scale of the analog output.
4 = 16 m
5 = 8 m
Sets the distance below which the alarm signal will change to a low state. There is
0.5 ... 254 hysteresis on this setting equal to the "#Rn:" resolution setting or 0.06 m
whichever is the greater value.
0 = Off Enables the alarm signal latch. This keeps the alarm in the active low state after
1 = Active an alarm event until it is cleared by sending the "#X" command to the serial port.
Clears the alarm latch if it is enabled using the "#L1:" command.
Stops the laser from firing.
Starts the laser firing.
0 = Serial
Selects between the measuring distance or measuring speed.
