The Frequency Out option cards each have 3 outputs, distributing a 1MHz signal, 5MHz or 10 MHz signal (depending on the card model). All 3 outputs are configured as a single output and will appear as such in the SecureSync Web UI, numbered sequentially by card instance, starting with 0 (except the 10 MHz option card, which starts with no.1 because of the built-in 10 MHz output.)

Frequency Output: Edit Window

To configure the settings of a Frequency Output, go to its Edit window. For instructions, see: Configuring Option Card Inputs/Outputs.

The list entry for this card is named: 1/5/10 MHz BNC (or: TNC)

The connector numbers are: J1…J3.

Note: SecureSync starts numbering I/O ports with 0 (only 1PPS and 10 MHz outputs start at 1, because of the built-in outputs).

The Edit window allows the configuration of the following settings:

  • Signature Control: Controls when the output will be present; see Signature Control.

Frequency Output: Status Window

To view the settings of a Frequency output, go to its Status window. For instructions, see: Viewing Input/Output Configuration Settings.

The Web UI list entry for this card is named: 1/5/10 MHz BNC (or: TNC).

The connector numbers are: J1…J3.

Note: SecureSync starts numbering I/O ports with 0 (only 1PPS and 10 MHz outputs start at 1, because of the built-in outputs).

The Status window displays the following settings:

  • Signature Control: Controls when the output will be present. See also: Signature Control.
  • Frequency: The frequency of the output: 1MHz, 5MHz or 10 MHz, depending on the card model.
