After clicking the "Start" button the simulation will start, and NMEA sentences will be sent to the selected output port of the PC, until the "Stop" button is pressed. Note that only those NMEA sentences will be sent that are checked in the "NMEA sentences" panel.
All sentences 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 instrument is used it can continue where it stopped. Note: saving is an optional setting in the General Settings.
A short description of each field follows.
Object tag
Optional, to give this instrument a name for easy identification.
To make the simulation a bit more realistic you can enter a Percentage of random depth variation. The depth will then vary randomly with this percentage.
