On firmware versions before R020816, XDS packets were NOT retained after a
power loss to the 8084 even though the internal clock is battery backed up. On
these earlier firmware versions, in order to guarantee that the packets will be sent
continually you must either provide uninterruptable power to the 8084 or re-
enable the packets using MetaCast 2 after a power failure. The preferred solution
however is to update the firmware in the 8084 to R020816 or later where the XDS
packers are retained after power loss.
B.5.9 Monitoring the Time of Day and Time Zone Packets in MetaCast 2
The current time and date being read from the encoder is shown on the top text box of the Clocks
page. The Current time is also shown on the Status window at the bottom of the screen.
The encoder Status window shows the XDS packets that are currently being transmitted by the
8084AD. You should see an entry for the Time of Day
