Output Mode: This field determines when the output data will be provided. Avail-
able Mode selections are as follows:
Broadcast—Event Messages are automatically broadcast when they are cre-
ated by an event. If a new event happens while an older message is being
broadcast, the new message will be queued in a “First-in, First-out” manner.
When the message has finished, the next message out of the queue will be
broadcast.
Request—Event Messages are only broadcast in response to a Request Char-
acter. New messages will be queued in a “First-in, First-out” manner.
Request character: This field defines the character that SecureSync needs to
receive in order for a message to be provided when in “Request” mode. This field
will only appear if the Output Mode is set as “Request Broadcast.”
Timescale—Used to select the time base for the incoming ASCII time code
data. The entered Timescale is used by the system to convert the time in the
incoming ASCII 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 15-
February-2021, this is 18 seconds ahead of UTC time)
A local clock set up through the Time Management Page—This option will
appear under the name of the local clock you have set up. Refer to "The Time
Management Screen" on page166for more information on configuring and
reading the System Clock. Local timescale allows a Local Clock to apply a time
offset for Time Zone and DST correction.
Note: The Timescale of the input (as configured in the ASCII time source)
must be set correctly, especially if other input references are enabled. Fail-
ure to configure the Timescale of the input correctly could result in time
jumps occurring in the System Time when input reference changes occur.
These time jumps could affect NTP and normal operation of the system.
Baud Rate: Determines the speed that the output port will operate at.
Data Bits: Defines the number of Data Bits for the output port.
