Although the time zone must be entered as hours and minutes, the XDS Time Zone
packet will only transmit the time zone hours. This is a limitation of the definition of
the time zone packet in EIA-608-B.
SERIAL PROTOCOL
8083XDS-AD Analog and SD-SDI XDS Encoder
Example:
^Ac<sp>13:10:00<sp>5<sp>ON,<sp>DSO=ON<cr>
Set local time to 1:10 pm in EDT (Daylight Saving
Time in effect), Daylight Saving Time observed.
^Ac<sp>13:10:00<sp>5<sp>ON,<sp>DSO=OFF<cr>
Set local time to 1:10 pm in EST (Daylight Saving
Time in effect), Daylight Saving Time not observed.
(e.g. as in Indiana)
^Ac<sp>06:10:00<cr>
Set local time to 6:10 am. Time zone, DST and DSO
unchanged.
^Ac<sp>13:10:00<sp>4:30<sp>OFF<sp>DSO=ON<cr>
Set local time to 1:10 pm in Newfoundland Time
Zone with Daylight Saving Time not in effect, but
Daylight Saving time observed
The DST bit instructs the encoder whether Daylight Saving Time is
currently in effect. The DSO bit instructs the encoder whether Daylight
Saving Time is observed in this region. The encoder must know this
information when converting between local time and UTC time internally.
Most regions in North America observe Daylight Saving Time according to
the following rule: ON in the summer, starting on the first Sunday in April.
OFF in the winter, starting on the last Sunday in October. Other parts of the
world follow different rules for DST.
4.3.12 Set / Report Calendar Date
This command will return the current calendar date or will allow the internal
calendar date to be set. The encoder will maintain the correct date even
through power outages.
Command:
^Ad<cr>
Example results:
Local date is: Jan/09/2000 Mon.
Command:
^Ad<sp>U<cr>
Example results:
UTC date is: Jan/10/2000 Mon.
Command:
^Ad<sp>mm/dd/yyyy<sp>day of week<sp>U<cr>
