order. That is, 1,2,3,4.
You may not skip a
priority (e.g. 1,3,4).
Skipping a priority will
cause the round robin
search to stop at the blank
priority number.
Priority sequence is round
robin and will progress in
circular order until a sync
is achieved. Time
between steps may be as
long as minutes since
achieving sync with any
one master source is not
instantaneous.
If 1PPS the TOD clock
will set the
YY,DDD,HH,MM,SS or it
may be overridden by
command. If using 1PPS
as a transfer reference in
PTP Master Clock mode
set UTC time, if an IRIG
reference is applied that
does not include the year,
the YYYY value will be
that read from the TOD
until overridden by
command.
