Arguments
for Command
(Note that all arguments are ASCII numeric codes from 48 to 57)
or Query
3 bytes Command or Query.
Sets or returns CnC Re-acquisition time in the form xxx, where:
xxx = value from 10 to 999.
Note: This is the time wherein CnC will start searching for the delay
and frequency offset if a long duration of unlock occurs.
Example : <0001/CRA=010{CR}
4 bytes Query only.
When CnC is enabled and locked, returns the ratio, in 1 dB steps,
between the interferer and the desired signal power. Reporting format
varies as follows:
Example 1: >0001/CRM=+02{CR}{LF} (interferer > desired)
(form = sdd, where: s = sign (+/–), dd = value in 1 db steps)
Example 2: >0001/CRM=LT10{CR}{LF} (less than –10 dB)
Example 3: >0001/CRM=GT10{CR}{LF} (greater than +10 dB)
Example 4: >0001/CRM=99.9{CR}{LF} (not locked or CnC not
enabled)
6 bytes Command or Query.
Sets or returns CnC min/max delay value in milliseconds, in the form
xxxyyy, where:
xxx = min delay value from 0 to 300 ms
yyy = max delay value from 0 to 300 ms
Example: <0001/CSD=010300{CR}
6 bytes Command or Query.
Sets or returns the date in the form ddmmyy, where:
dd = day of the month (01 to 31),
mm = month (01 to 12)
yy = year (00 to 99)
Example: <0001/DAY=240457{CR} (April 24, 2057)
