Once selected, the Format Group may offer a choice of Formats. For more
information on supported Formats , see "Time Code Data Formats" on
page277.
Format 1: Selects either the first of up to three, or the only format mes-
sage to be output.
Format 2: Selects the second consecutive format message to be out-
putted. Select “None” if only one output format is desired. “None” will
be the only choice available if Format 1 is “None.”
Format 3: Selects the third consecutive format message to be out-
putted. Select “None” if only one output format is desired. “None” will
be the only choice available if Format 2 is “None.”
Signature Control: Signature Control controls when the selected ASCII data
output format will be present;see "Signature Control" on page60.
Output Mode: This field determines when the output data will be provided.
The available Mode selections are as follows:
Broadcast: The format messages are automatically sent out on author-
ized condition (Signature control), every second a message is gen-
erated in sync with the 1PPS.
Request (On-time): A format message is generated in sync with 1PPS
after the configured request character has been received.
Request (Immediate): A format message is generated as soon as the
request character is received. As this selection does not correlate the
output data to the on-time point for the message, in Data Formats that
do not provide sub-second information (such as Formats 0 and 1
whereas Format 2 provides sub- second information), it should be
noted that the output data can be provided immediately, but a time
error could occur when using the on-time point of the message in addi-
tion to the data for timing applications.
Note: The choices available in this field are determined
by the choices of Format Group and Format.
Timescale: Used to select the time base for the incoming 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:
