Description of commands
/Debounce =50;
This command configures the time that the trip inputs have to be valid and stable before the DSU500
will respond. A value of 50 means the trip has to be valid for 50mS. You may set any value from 10mS
up to 5000mS. (5 seconds)
This can normally be left at 50 but if a particularly electrically noisy environment is causing false
triggers, then raise this value to fix the problem.
/Invert =0000;
This command allows you to invert the operation of any or all of the trip inputs so that the trip is active
when the trip line is open circuit or high.
For example:
/Invert =1000;
Trip 1 is inverted. Message 1 plays when Trip 1 is open circuit.
The above example could be used when the DSU500 is connected to a standard PIR sensor which has a
normally closed contact output that opens when the PIR detects movement.
The numbers following the ‘=’sign can only be ‘1’ or ‘0’
Trip 1 is the first digit, Trip 2 is the second digit etc
So for example, to invert trips 3 & 4, set the command as follows:
/Invert = 0011;
Trips 3 & 4 inverted
/Oneshot = 0000;
This command configures the trip inputs individually to allow one shot triggering.
One shot triggering is used to prevent a track playing continuously even if the Trip remains active at the
end of the sound track.
To re-trigger the track, the Trip must be released and then re-applied after the sound track has finished
playing.
This would normally be used when triggering from a contact that remains closed for longer than the
sound track such as certain PIR sensors and timer switches.
For example:
/Oneshot
=1000; Trip 1 is one shot enabled.
The numbers following the ‘=’sign can only be ‘1’ or ‘0’
Trip 1 is the first digit, Trip 2 is the second digit etc
So for example, to one shot trips 1 & 4, set the command as follows:
/Oneshot = 1001; Trips 1 & 4 one shot enabled
/Interrupt = 0;
This command configures how the DSU500 responds when another trip comes in while playing.
The four options are:
/Interrupt = 0; No interrupt - While a track is playing, all trips are ignored.
/Interrupt = 1;
Priority interrupt - While a track is playing, trips of a lower value will be
accepted and the current track will be cancelled.
/Interrupt = 2;
Any other interrupt - While a track is playing, any other trip will be accepted and
the current track will be cancelled.If two trips are active at the same time, the
lowest one will take priority.
/Interrupt = 3;
Any and self interrupt - While a track is playing, any other trip will be accepted
and the current track will be cancelled.If the same trip is released and then
re-applied, the track will be restarted from the beginning.If two trips are active at
the same time, the lowest one will take priority.
