Setting Detection Sensitivity via the ASCII Interface:
In addition through the supplied PC program interface, the radar also allows ASCII
programmatic sensitivity setting.
Over the serial interface, send in ASCII the following commands:
Sensitivity:nn\n and
Sensitivity?\n
The fiirst command will set the detection sensitivity to "nn" where nn is from 10 to 99
and is a percentage of the maximum detection range.
If sensitivity was set correctly, the unit replies with
OK\n
The second command will report sensitivity.
Note 1: All settings, including sensitivity, are written to FLASH memory and are non-
volatile. DO NOT update settings on a periodic basis, e.g. every second or every minute.
Only change settings when the user needs it. The FLASH memory has a limited number
of write cycles and will wear out with excessive (>10,000) number of writes. On the
other hand, setting the variable to the
same value
repeatedly is OK because the radar
recognizes that the variable has not changed and does not update it in FLASH.
Note 2: Other configuration parameters may also be set via ASCII interface. These are
described in greater detail in our ASCII interface application note. Please contact
Houston Radar for this document.
