With a time sync module, the console's internal clock can be synchronized
to an external time reference unit, such as a DCF77 or GPS receiver, or a
Mobatime clock providing a serial output signal. The current software of
the module supports AFNOR and Seiko protocols as well as SMPTE bi-
phase timecode (Leitch).
For either of these time reference units (except AFNOR and SMPTE) the
connector labeled RS232 is used. For ANOR and SMPTE signals, a trans-
former-balanced input is available on the RS422 connector. Please note the
configuration
(chapter 16.10), depending on the type of reference unit being used.
Note: The Time Sync Module software version is completely independent of the
console software; this means that a Time Sync Module with the most re-
cent software version supports all time sources available, even if installed
in a console with the earliest software version.
