Simulcast (CTCSS/Data Clock) [1204-14]

The Simulcast CTCSS/Data Sync/Data Clock Option Card provides CTCSS, data
clock, and alarm outputs through relays for the SecureSync platform through one
DB-9 and one RJ-12 connector. The maximum number of cards installed is six (6).
a. Connector: DB-9
b. Connector: RJ-12

Period: Sets the period of the square wave (in ns or μs scale).
The wave's frequency will display at the top of the window once
you have configured the output. The frequency is calculated
based on the Period and Period Correction settings.
Period Correction: Period correction allows for the generation of
more precise frequencies at the expense of additional period jitter.
Over a length of time, the true square wave period comes to:
Period + [(numerator/denominator) * 5 ns]
Outputs:
