The decimal points shown above are not actually transmitted in the data stream, but their
position is implied. The displays are configured to show the decimal point in this position.
*Time Deviation is output in two formats in the same data stream: 33±s.ss and 34±sss.sss.
Output for the 33±s.ss format will be +9.bb when the measured value exceeds +9.99 (b =
blank). It will be -9.bb when the measured value is less than -9.99.
Output for the 34±sss.sss format will observe the following conventions for out-of-range values
and leading blanks. Decimal points are implicit and do not appear in the data stream.
Time Deviation Range Format (b=blank)

-99.99 to -10.00 -bss.sss
-9.99 to -0.01 -bbs.sss
+0.00 to +9.99 +bbs.sss
+10.00 to +99.99 +bss.sss

Table C.6: Option 28 B2 Broadcast, Time Deviation Values
Start Broadcast Mode–ASCII
Command: B7, O7
B7 configures the Standard RS-232 broadcast mode to send Time, Frequency, and Phase De-
viation, once per second, in ASCII format. O7 configures the Option RS-232 broadcast mode to
send 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
C
broadcast mode, Local:
mm/dd/yyyy hh:mm:ssL ss +f.fff +t.tttt ppp.ppp vvv.vv
