NetClock/NTP Network Time Provider Instruction Manual

NOTE:
Data Format 1 has an available modification that may be made to the data stream
structure. 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, the following procedure
will change the Data Format 1 structure to provide this.
Connect to the Serial Setup Interface port with a PC running HyperTerminal OR telnet into the
NetClock using the IP address of the unit.
To change Data Format 1 output on a Serial port to a leading 0, type:
ser mod ser[1/2] 1 zero
<enter>
(Where 1 or 2 is the desired Serial port number)
To change Data Format 1 output on a Remote RS-485 port to a leading 0, type:
rem mod rem[1/2] 1 zero
<enter>
(Where 1 or 2 is the desired Remote port number).
To change Data Format 1 output on a Serial port back to a leading space, type:
Ser mod ser[1/2] none
<enter>
(Where 1 or 2 is the desired Remote port number).
To change Data Format 1 output on a Remote RS-485 back to a leading space, type:
rem mod rem[1/2] none
<enter>
(Where 1 or 2 is the desired Remote port number).

Format 2
This format provides a time data stream with millisecond resolution. The Format 2 data stream
consists of indicators for time synchronization status, time quality, leap second and Daylight
Saving Time. Time data reflects UTC time and is in the 24-hour format. Format 2 data structure
is shown below:
NOTE:
Format 2 cannot be configured for a Time Zone Offset or with automatic Daylight
Saving Time adjustment. Attempting to configure a Local clock using Data Format 2
with either a Time Zone Offset or automatic DST rule will result in an error message.
CR LF IQYY ^ DDD ^ HH:MM:SS.SSS ^ LD
where:
CR = Carriage Return
LF = Line Feed
I = Time Sync Status (space, ?, *)
Q = Quality Indicator (space, A, B, C, D)
