B7 configures COM1 to broadcast Time, Frequency, and Phase Deviation, once per second, in ASCII
format. O7 configures COM2 to broadcast Time, Frequency and Phase Deviation, once per second, in ASCII
format.
Response: broadcast mode, UTC:
mm/dd/yyyy hh:mm:ssU ss +f.fff +t.tttt ppp.ppp vvv.vv
< CR >< LF >
broadcast mode, Local:
mm/dd/yyyy hh:mm:ssL ss +f.fff +t.tttt ppp.ppp vvv.vv
< CR >< LF >
Where:
mm/dd/yyyy = Date
hh:mm:ssU = Time of Day, UTC
(or)
hh:mm:ssL
= Time of Day, Local
ss = Status
first character is Reference Status:
0 : Locked;
1 : Unlocked;
second character is clock status per IEEE C37.118.1
+f.fff signed Frequency Error in Hz.
+t.tttt signed Time Deviation in seconds.
ppp.pp Phase Angle, 0 to 360 degrees.
