Enable
This property must be set to YES for the system to make self-timed transmissions. This property
is sent to the Satlink to configure it and uses the field to control its own scheduling.
Time
Time is the transmission time assigned to the station. Each station will have a unique
transmission time, rate and channel assigned by NESDIS, EUMETSAT or other authorized agency.
The transmission time is entered in UTC.
Interval
The Rate, along with the transmission time determines when transmissions are made. The units
for the rate are HH:MM:SS. Typical rates are 01:00:00 for hourly transmissions and 04:00:00 for
transmissions every 4 hours.
Channel
This property defines the channel that Satlink will use to make the self-timed transmission.
Center in Window
This box instructs Satlink to center each timed transmission in the transmission window.
Normally, a transmitter has a transmission window that is larger than the length of the
transmission it must make. When “Center in Window” is selected, Satlink will delay each
transmission so it is centered in the window. The Window size is entered in the Window
Property on this dialog.
WindowLength
This property defines the size of the window, in HH:MM:SS, that is given for the transmission.
