STANAG Output: Edit Window

To configure a STANAG output, go to its Edit window. For instructions, see: Configuring Option Card Inputs/Outputs.

The Web UI list entries for these cards are: STANAG Out and STANAG Out, Isolated.

The outputs are named: Stanag HQ Output [number].

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:

Under General Settings:

  • Level of Single-ended Signals: 10 V or 5V can be selected for the TOD 1 and 1PPS Output.
  • Generate Time Fault Discrete (TFD):
    • Enabled: The TFD signal uses the “Threshold to activate” value to provide the level of TFD.
    • Disabled: The TFD signal is always valid.
  • Threshold to activate TFD: If the TFD is activated, the user can select the TFOM value threshold. Below this value, the TFD is high, otherwise the TFD is low.
  • Generate Bit Synchronization (BS):
    • Enabled: The second STANAG signal (TOD 2) is used to send the BS (Bit Stream) signal used with STANAG 4430-STM. When BS is active, the configuration of TOD 2 is superseded and only used for BS.
    • Disabled: The second STANAG signal (TOD 2) can be used to send an independent TOD.
  • Timescale: Used to select the time base for the incoming time code data. The entered Timescale is used by the system to convert the time in the incoming data stream to UTC time for use by the System Time. The available choices are:
    • UTC—Coordinated Universal Time ("temps universel coordonné"), also referred to as ZULU time
    • TAI—Temps Atomique International
    • GPS—The raw GPS time as transmitted by the GNSS satellites (as of July, 2015, this is 17 seconds ahead of UTC time)
    • A local clock set up through the Time Management Page—Refer to The Time Management Screen for more information on how to configure and read the System Time. Local timescale allows a Local Clock to apply a time offset for Time Zone and DST correction.

The incoming input time information may be provided as local time, but System Time may be configured as UTC time, so internal computations need to be performed. With the Timescale field set to “Local”, select the name of a previously created Local Clock. The Time Zone and DST rules, as configured in the Local Clock will be applied to the front panel time display. Refer to for more information on Local Clocks.

Configurable settings for each Time of Day are:

  • Signature Control: Used to control when the signal will be present. This function allows the modulation to stop under certain conditions, see also Signature Control.
  • TOD Format: The user-selectable format to be used. Available formats include:
    • STANAG 4246 HQI
    • STANAG 4246 HQII
    • STANAG 4372 HQIIA
    • STANAG 4430 STM
    • STANAG 4430 XHQ
    • ICD-GPS-060A BCD
    • ICD-GPS-060A HQ
    • DOD-STD-1399 BCD
  • Electrical Format: Selects signaling on either RS-485 or TTL (supporting up to 10 V levels) signal lines.
  • Time Scale: Used to set the desired time scale (UTC, TAI, GPS, or Local). See above.
  • Offset (ns): Provides the ability to account for STANAG Line (TOD1 and TOD2 independently) cable delays or other latencies in the STANAG output. Available Offset range is –500 to +500 ms in 5ns steps.

Configurable settings under 1PPS Output are:

  • PPS Signature Control: Used to control when the signal will be present. This function allows the modulation to stop under certain conditions, see also Signature Control.
  • PPS Offset (ns): Used to account for 1PPS cable delays or other latencies in the 1PPS output. Available Offset range is –500 to +500 ms in 5ns steps.
  • PPS Edge: The operator can select if the output signal is a rising or falling edge pulse.
  • PPS Pulse Width: Configures the Pulse Width of the 1PPS output. The Pulse Width is entered and displayed in nanoseconds (the default Pulse Width is 200 ms).
  • PPS Electrical Format: Selects signaling on either RS-485 or TTL (supporting up to 10 V levels) signal lines.

STANAG Output: Status Window

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

The Web UI list entries for these cards are: STANAG Out and STANAG Out, Isolated.

The outputs are named: Stanag HQ Output [number].

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:

Under General Status:

  • Level of Single-ended Signals: 10 V or 5V will be indicated for the TOD 1 and 1PPS Output.
  • Generate Time Fault Discrete (TFD):
    • Enabled: The TFD signal uses the “Threshold to activate” value to provide the level of TFD.
    • Disabled: The TFD signal is always valid.
  • Threshold to activate TFD: If the TFD is activated, indicates the TFOM value threshold. Below this value, the TFD is high, otherwise the TFD is low.
  • Generate Bit Synchronization (BS):
    • Enabled: The second STANAG signal (TOD 2) is used to send the BS (Bit Stream) signal used with STANAG 4430-STM. When BS is active, the configuration of TOD 2 is superseded and only used for BS.
    • Disabled: The second STANAG signal (TOD 2) can be used to send an independent TOD.

    • A local clock set up through the Time Management Page—Refer to The Time Management Screen for more information on how to configure and read the System Time. Local timescale allows a Local Clock to apply a time offset for Time Zone and DST correction.
