Name
Description
Answer
PRT
Change data
format
After entering this command,
the sensor will give an ASCII
answer then change its data
format to binary.
OK
V
Device
Identification
Sensor will report information
about itself
- device type
(Ex. 603)
- firmware version
(Ex. 40)
- serial number
(Ex. 19999)
- base distance
(Ex. 125)
- measurement range
(Ex. 500)
Note:
603 is an internal designation for the
AR100
The following codes all return “OK” when entered except Rx,
which will just change
the units of the output measurements upon being entered.

Description
x values
Wx
Save and recovery
0 - save current parameters to non-volatile memory
1 - recover default parameters (
Note:
this will not change the
communication protocol)
Rx
Measurement units

– 16384)
1 - millimeters
2 - inches
Ox
Sensor ON/OFF
0 - laser OFF
1 - laser ON (default)
