As the Tone Generator is connected to line 5 we click on the far left LED to indicate that

we want it in the “on” state. As we click on one or more LEDs the port value will change.

Once the LED for line 5 is illuminated we can enter the duration we want it to stay on for.

In the example shown we have chosen a 1000ms.

To enter the event into the schedule (or program) we click on “Append Row”. Note that the

status of each line is indicated by a 1 or 0, for on or off repectively. The decimal port value

along with the duration is also shown. The sequence begins at 1000ms after being started.

Here we can see that our first event begins at 1000ms and finishes at 2000ms. If we wish

to change the default 1000ms offset select Tools|Options from the menu bar.

Usually we define a sequence with a series of on and off events. So next we need to add

an off period to the sequence we are constructing. Ensure that all LEDs are off then add

an off duration of 5000ms.

Here we have added three “on” events, each of which will make the Tone Generator sound

for exactly 1000ms. Each event is separated by a 5000ms silent “off” period. We can see

that the total run time will be 19,000ms. We are also free to edit the sequence should the

need arise. Select the row you wish to edit from the lower sequence grid and click on the

appropriate “Event Controls” button.

Once we have saved the sequence and chosen a Real Time Log file we can click on the

“Run” button.
