Valcom Master Clock
Inputs - Sync-Wire Inputs Installation
This system can accommodate both a primary and secondary (for backup) auxiliary time synchronization input.
The following protocols cannot be used simultaneously: 59 minute sync, 58 minute 1-4 sync, National Time/
Rauland, Dukane Digital, Rauland Digital and once a day Pulse. An example of a configuration would be
SNTP being the primary input and 58 minute correction being a secondary input. Setting the primary source
to 59 minute sync and the secondary source to Dukane digital would be an incorrect configuration.
