APPENDIX
Timescale : 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:
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."
Baud Rate : The speed that the output port will operate at.
Data Bits : The number of Data Bits for the output port.
Parity : The parity checking of the output port.
Stop Bits : The number of Stop Bits for the output.

Broadcast —Event Messages are automatically broadcast when they are created
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 mes
sage has finished, the next message out of the queue will be broadcast.
Request —Event Messages are only broadcast in response to a Request Character.
New messages will be queued in a "First-in, First-out" manner.
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—This option will appear
under the name of the local clock you have set up. Refer to "The Time Man
agement Screen" on page 140 for more information on configuring and reading
the System Time. 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 time source) must be set cor
rectly, especially if other input references are enabled. Failure to configure the
Timescale of the ASCII 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.
