Product manual
n values
0 = 1.00 m
Selects the resolution of each reading taken.
1 = 0.50 m
2 = 0.25 m
For the value 0 the result is a single byte, for all other values it is two bytes.
3 = 0.12 m
For values of 0 to 5 the result is provided as a snapshot.
4 = 0.06 m
5 = 0.03 m
For a value of 6, the "Time series filter" changes the results to a recursive Kalman
filter output.
10 ... 3052
Sets the rate at which new results are output from the serial port.
10 ... 1526
The actual value may be lower than the entered value depending on the setting
10 ... 763
"#Rx:" resolution.
10 ... 95
Only whole number fractions of 3052 will give an exact match between the entered
and actual values.
10 ... 95
10 ... 3052
Sets the rate at which the analog port and the alarm signal are updated with
distance readings.
10 ... 1526
The actual value may be lower than the entered value depending on the setting
10 ... 763
"#Rx:" resolution.
10 ... 95
Only whole number fractions of 3052 will give an exact match between the entered
and actual values.
10 ... 95
0 = 128 m
1 = 64 m
Selects the maximum distance that produces 2.56 V on the analog port. This value
2 = 32 m
changes the scale of the analog output.
3 = 16 m
4 = 8
m
Sets the distance below which the alarm signal will change to a low state. There is
hysteresis on this setting equal to the "#Rx:" resolution setting or 0.06m 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.
