Once selected, the Format Group may offer a choice of Formats. For more
information on supported Formats, see
page 560.
Format 1: Selects either the first of up to three, or the only format
message 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
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
authorized condition (Signature control), every second a message is
generated 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
addition to the data for timing applications.
