Description Type of the measurement message sent
Notes 0: No message
1:
<+|-> SSS <SP>(km/h|mph)<CR><LF>
<+|- > is the character ‘+’ (approaching traffic) or ‘-‘ (receding traffic) in ASCII,
SSS (3 decimal digits in ASCII) is the measured speed in the current speed unit.
<SP>
is the space character in ASCII
(km/h|mph) (4 chars) is the current speed unit
<CR> is the carriage return character in ASCII and
<LF> is the line feed character in ASCII.
2:
SSS <K|M><I|O><CR><LF>
SSS (3 decimal digits in ASCII) is the measured speed in the current speed unit.
<K|M> is the current speed unit: ‘K’ for km/h or ‘M’ for mph.
<I|O>
is the character ‘I’ (approaching traffic) or ‘O’ (receding traffic) in ASCII,
<CR> is the carriage return character in ASCII and
<LF> is the line feed character in ASCII.

<+|- > is the character ‘+’ (approaching traffic) or ‘-‘ (receding traffic) in ASCII,
SSS (3 decimal digits in ASCII) is the measured speed in the current speed unit.
<CR> is the carriage return character in ASCII and
<LF> is the line feed character in ASCII.
4:
*S SSS <CR><LF>
*S (two fixed chars),
SSS (3 decimal digits in ASCII) is the measured speed in the current speed unit.
<CR>
is the carriage return character in ASCII and

SSS (3 decimal digits in ASCII) is the measured speed in the current speed unit.
<SP>
is the space character in ASCII
(km/h|mph) (4 chars) is the current speed unit
DDD (3 decimal digits in ASCII) is the measured range in the current range unit.
<SP>m is the space character in ASCII followed by the current range unit (meter)
<CR> is the carriage return character in ASCII and
<LF> is the line feed character in ASCII.
9 : TTTTTTTTTT <SP> ms <SP><+|-> SSS <SP>(km/h|mph)<SP> DDD <SP>m<CR><LF>
TTTTTTTTTT (10 decimal digits in ASCII) Time elapsed in milliseconds since radar start.
