GPS7 GPS Synchronization and Timecode module
If an SDI7 modul
e is installed, the SDI embedded timecode (when enabled) also
includes the SMPTE309 date, time-zone offset, and DST enabled/disabled fields.
The content of these fields depends on the current SMPTE309 mode setting on the
GPS7 module (Ignore, Use As Input, or Use As Input/Output).
The Status display for the module now includes the received ST309 time zone and
DST data (if present).
