Spectracom Format 1S

Format 1S (Space) is very similar to Format 1, with the exception of a space being the first character of Days 1 through 9 of each month (instead of the leading “0” which is present in Format 1).

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 single digit day of the month for days 1 through 9 (i.e. 1, 2, etc.), select Format 1S.
  • If your device requires the two digit day of the month for days 1 through 9 (i.e. 01, 02, etc.), select Format 1 instead. Refer to Spectracom Format 1 for information on Format 1.

Example message:

CR LF I ^ WWW ^ DDMMMYY ^ HH:MM:SS CR LF

Where:

CR Carriage Return
LF Line Feed
I Time Sync Status (space, ?, *)
^ Space separator
WWW Day of Week (SUN, MON, TUE, WED, THU, FRI, SAT)
DD Numerical Day of Month (1-31)
MMM Month (JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC)
YY Year without century (99, 00, 01, etc.)
HH Hours (00-23)
: Colon separator
MM Minutes (00-59)
SS Seconds (00-60)

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.

Example:

FRI 20APR15 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.
