Spectracom SecureSync User Manual

Note: The choices available in this field are determined by the
choices of Format Group and Format.
Time Scale: Used to select the time base for the incoming data. The entered Timescale is
used by the system to convert the time in the incoming data stream to UTC time for use by
the System Time. The available choices are:
UTC: Coordinated Universal Time ("temps universel coordonné"), also referred to
as ZULU time
TAI: Temps Atomique International
GPS: The raw GPS time as transmitted by the GNSS satellites (as of July, 2015,
this is currently 17 seconds ahead of UTC time).
If GPS or TAI time is used, then the proper timescale offsets must be set on the
MANAGEMENT/OTHER/Time Management page. (See "The Time Management Screen"
on page146 for more information on how to configure and read the System Time).
Local timescale allows a Local Clock to apply a time offset for Time Zone and DST cor-
rection.
A Local Clock can be set up through the Time Management page: This option will
appear under the name of the local clock you have set up. See for more inform-
ation. Local timescale allows a Local Clock to apply a time offset for Time Zone
and DST correction.
The incoming input time information may be provided as local time, but System
Time may be configured as UTC time, so internal computations need to be per-
formed. With the Timescale field set to “Local”, select the name of a previously cre-
ated Local Clock. The Time Zone and DST rules, as configured in the Local Clock
will be applied to the front panel time display. See for more information on Local
Clocks.
Baud Rate: Determines the speed at which the output port will operate.
Data Bits: Defines the number of Data Bits for the output port.
Parity: Configures the parity checking of the output port.
Stop Bits: Defines the number of Stop Bits for the output.
ASCII Time Code Output: Status Window
To view the current settings of the ASCII Output, go to its Status window. For instructions, see:
"Viewing Input/Output Configuration Settings" on page347.
The Web UI list entries for this card are: ASCII TIMECODE RS-232 and ASCII TIMECODE RS-
485.
