Application Examples
-
Automatic Playback on Power-up
1. Repeat continuously on power-up.
Intended Operation
- Play file #001 on power-up if switch #1 is turned on.
- Play file #002 on power-up if switch #2 is turned on.
.........
- Play file #008 on power-up if switch #8 is turned on.
- If more than one switch is turned on, play all corresponding
files sequentially
- Repeat the file(s) until power is turned off.
Required Text in MODE.TXT
RN
Notes
- A direct short can be used if there is only one sound file.
- If priority is required, use DN instead of RN. In this case
switch #1 has the highest priority, switch #2 has the sec-
ond highest priority, and switch #8 has the lowest priority.
If more than one switch is turned on, only the file for the
switch of the highest priority will be played.
2. Repeat at intervals on power-up.
Intended Operation
- Same as the example above but play files at intervals.
Required Text in MODE.TXT
RS
N001=F001,W06000
N002=F002,W06000
.....
N008=F008,W06000
END
Notes
- W06000 is a delay loop of 6000 x 0.1 second = 10 minutes,
so the file(s) will be played at an interval of 10 minutes, one
file at a time.
Application Examples
-
Using Normally Closed Switches & Sensors
Normally closed switches and sensors are often used in security
systems.
1. Play when the switch/sensor opens, with no priorities.
Intended Operation
- Play file #001 when sensor #1 opens.
- Play file #002 when sensor #2 opens.
- Repeat the sound for as long as the sensor is open.
- If multiple sensors are open at the same time, play all
corresponding files sequentially.
Required Text in MODE.TXT
RN+
Notes
- Unused inputs must be connected to the ground, as shown
in the wiring diagram.
2. Play when the switch/sensor opens, with priorities.
Intended Operation
- Same as the example above, but if multiple sensors are
open at the same time, the sensor of the highest priority
prevails.
Required Text in MODE.TXT
DN+
Notes
- The sensor connected to T1 has the highest priority, and
the sensor connected to T8 has the lowest priority.
3. Play when the switch/sensor opens, but don’t repeat.
Intended Operation
- Play file #001 when sensor #1 opens.
- Play file #002 when sensor #2 opens.
- Do not repeat the sound.
Required Text in MODE.TXT
DS+
N001=F001,J999
N002=F002,J999
H999=J999
END
Notes
- The system will stay in the “H999=J999” endless loop for as
long as the sensor is open. The system will not respond to
other sensors until this one is closed.
