Up to 10 boundary clocks
and/or PTP terminal
devices may be
synchronized by the JTE.

PRIORITY A
source
^YPAx
x=1,2,3,4, where
1 = IRIG
2 = GPS (if present)
3 = PTP/NTP (factory default)
4 = 1PPS
Priority A is always the
DESIRED MASTER, if
available.
NTP w1ll not be available
without a server address.
GPS will not be available
without the option
installed.
Priority selections must
always be in sequential
^YPA?
Query current value
Return =(19h)PA(32h)value<CR> as
ASCII
Value=NONE, IRIG, GPS, PTP/NTP or
1PPS
