The following settings are editable:
Format Group: Determines the time code message format category (see
also "Time Code Data Formats" on page277.) Choices are:
Auto
Spectracom
NMEA
ICD-153
EndRun
Format: Once a Format Group has been selected, one or more Format
fields may appear, allowing you to select one or more time code Formats. For
detailed specifications and limitations on the supported time code formats,
see "Time Code Data Formats" on page277.
Note: If Auto is chosen as the format group, the format will
automatically be Auto- detect. VersaSync will attempt to
identify the format of the incoming ASCII message.
Offset: Provides the ability to account for ASCII input cable delays or other
latencies in the ASCII input. The Offset value is entered and displayed in nano-
seconds (ns). The available Offset range is –500 to +500 ms.
Timescale: Used to select the time base for the incoming ASCII time code
data. The entered Timescale is used by the system to convert the time in the
incoming ASCII 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 5-
August-2019, this is 18 seconds ahead of UTC time)
A local clock set up through the Time Management Page: This option
will appear under the name of the local clock you have set up. Refer to
"The Time Management Screen" on page136 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 correction.
The incoming input time information may be provided as local time, but
System Time may be configured as UTC time, so internal computations
