User's Manual

“.ddd”: Programmable number of digits (0-3) after decimal point
“\r”: Carriage Return character, optional line ending
“\n”: Line Feed character, optional line ending
At least one or both of the line endings must be selected with ASCII format. No line
ending is not an option. Please see serial port configuration section for details on how to
select the above format.
Setting variables from an ASCII Terminal program via ASCII commands:
All the radar variables can be set and queried via a simple ASCII command set over the
serial port. ASCII commands may be issued via an ASCII terminal program like
Hyperterminal or Teraterm Pro. Alternatively, you may issue these commands from an
attached microcontroller.
All settings 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.
The ASCII commands are:
get (get a config variable)
set (set a config variable to a supplied value)
reset (resets the radar. Required after changing variables MO, MD and RS).
info (print out some info about the radar. Info is in the format of <tag>=<value>). New
tags may be added in the future. Order of tags may be moved around.
e.g.
To set a variable (variables are documented in the user manual):
set: <case sensitive var name> <value>[Enter]
e.g.
set:LO 5
alt format:
set:LO=5
sets the low speed cutoff to 5 etc.
Variables are case sensitive. Commands are not.
Success is indicated by an "OK".
Failure is indicated by either:
"ERROR" - Command was recognized but some other error occurred (variable not
present, format not correct, etc.)
<nothing returned> - Command was not recognized. Entire line was silently discarded.
This ensures that spurious things like enters or other ASCII chars do not generate
