The other option available in this menu is ‘polarity’ – where you can set each pin to
output either active Hi-Z (high impedance) or active low (i.e. connected to 0v).
The Events and Triggers port pinouts are:
Next is the list of the 8 available events, each of which can perform a variety of actions
when triggered.
Please highlight and select one of the events.
To set up an event:
1. For now, leave the ‘active’ setting ‘off’.
2. Select from the list what you want to ‘trigger’ the event; the choices are tuner
signal strengths, tuner audio levels, analog and digital inputs and outputs, unit
temperature and the status of the GPI pins.
3. Then select what ‘condition’ should cause the trigger – more than, less than
or in some cases equal to or not equal to.
4. Next, set the ‘value’ – the range here varies according to the trigger type.
5. Next is the time to wait after triggering before the event is activated (for
example, wait for 15 seconds of silence before activating the event).
6. ‘revert’ determines what happens when the trigger condition ends – does the
unit go back to its previous condition, and if it does, is it immediate or delayed?
7. Next you can set this revert delay.
The next parameters set what actions the event causes. You can set it to do any or all of
the following:
load a different preset;
change tuner frequencies;
change various output sources;
switch one of the GPO pins;
send an email;
send an snmp trap message.
Note that if you select ‘load preset’ as an action, the ‘revert’ function is greyed out and
not available. This is because a change of preset can involve a change of frequency of
