SAR aircraft
 

Operation

 
After clicking the "Start" button the AIS simulation will start, and the messages will be sent to the selected output port of the PC, until the "Stop" button is pressed. Note that only those messages will be sent that are checked.
 
All messages are shown in the I/O Port Monitor as they are output. When logging is ON (toolbar option), the sentences will also be written to the user selected log file.
 
Clicking the "Stop" button will suspend the operation, until "Start" is clicked again.
 
When the Transmit Interval is set to 0.0 the sentences are output as "single shot" each time you click the "Start" button.
 
Clicking the little X top-right will exit the object and save optionally all current values, so that next time the target is opened it can continue where it stopped. Note: saving is an optional setting in the General Settings.
