Spectracom Format 1
Format 1 converts the received day of year data (001-366) to a date consisting of day of week, month, and day of the month. Format 1 also contains a time synchronization status character, year, and time reflecting time zone offset and DST correction when enabled.
Available Formats 1 and 1S are very similar to each other. Most external systems utilizing Data Format 1 will look for a single-digit day of the month for day 1 through day 9, with a space in front of each digit ( ^1, ^2, ^3 … 10, 11… ), whereas other systems need to see a two digit day of the month for all days 1 through 9 with a leading 0 instead of a space (01, 02, 03… 10, 11…).
- If your device requires the two digit day of the month for days 1 through 9 (i.e. 01, 02 etc.), select Format 1.
- If your device requires the single digit day of the month for days 1 through 9 (i.e. ^1, ^2, etc.), select Format 1S instead. Refer to Spectracom Format 1S for information on Format 1S.
Format 1 data structure:
CR LF I ^ WWW ^ DDMMMYY ^ HH:MM:SS CR LF
|I||Time Sync Status (space, ?, *)|
|WWW||Day of Week (SUN, MON, TUE, WED, THU, FRI, SAT)|
|DD||Numerical Day of Month (01-31)|
|MMM||Month (JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC)|
|YY||Year without century (99, 00, 01, etc.)|
The leading edge of the first character (
CR) marks the on-time point of the data stream.
The time synchronization status character (
I) is defined as described below:
|?||When the receiver is unable to track any satellites and the time synchronization lamp is red.|
|*||When the receiver time is derived from the battery backed clock or set manually through the Setup Port Interface.|
FRI 20APR01 12:45:36
The example data stream provides the following information:
|Sync Status||The clock is not time synchronized to GNSS. Time is derived from the battery backed clock or set manually|
