a stop input and AUX08.WAV will not play in manual mode.
AUX01.WAV
Corresponds to manual input on IN1
AUX08.WAV
Corresponds to manual input on IN8 (when EN option is off)
AP-16+ Audio Files - Serial Control Mode
When using an external controller like the Prop-1, Prop-2, or Prop-SX, the AP-16+ can play any number of
files that are stored on the SD card. The only requirement is that the files are named using DOS 8.3 naming
convention, that is, the name of the file is eight characters or less, followed the the “.WAV” extension.
File naming examples:
BELL.WAV
Good file name
TELEPHONE.WAV
Bad file name – too many characters in name (9)
WOLF.MP3
Bad file name – extension is incorrect; format probably incorrect as well
Manual Control
An SFXnn.WAV file can be started by:
✔
Using a normally-open push-button/switch across the SWITCH INPUT terminals (E)
✔
Applying a 12- to 24-volt DC voltage to the 12-24V INPUT terminals (F)
✔
Connecting a PIR or compatible sensor to the PIR input header (G)
✔
Pressing the START button (H)
Manual control of an SFXnn.WAV file has two modes: 1) standard, and 2) random. The mode is controlled by
the position of the Random (?) option switch. When the random option switch is set to OFF the file to be
played is set by the AUDIO SELECT switch.
When the the Random (?) option switch is set to ON the AP-16+ will randomly select a file between
SFX00.WAV and the file set by the AUDIO SELECT switch. For example, if the Random option switch is set
to ON and the AUDIO SELECT switch is set to 7, the AP-16+ will play one of the files in the range
SFX00.WAV through SFX07.WAV. Note that the Random option uses internal logic so that all files within the
selected range are played before any is repeated, and the same file will not play back-to-back.
An SFXnn.WAV file will play until finished, even it another trigger input (dry contract, DC, sensor, or START
button) is detected. To stop an SFXnn.WAV file in progress:
✔
With the EN (autio stop enable) option switch on, press a button connected between 3V3 and IN8
✔
Send an “X” command through the TTL serial link
✔
Start an AUXnn.WAV file using one of the INx inputs
An AUXnn.WAV file can be started by connecting a normally-open push-button/switch between the 3V3
terminal and an INx (IN1..IN8) terminal. Note that the auxiliary inputs will override the current file if the
selection differs from the file presently playing, and are not subject to pre- and post-play delays (see below).
For example, if AUX01.WAV is playing and a button connected to IN2 is pressed, the AP-16+ will immediately
stop AUX01.WAV and start AUX02.WAV. If, while AUX02.WAV is playing, another input on IN2 is detected,
this input will be ignored. When the audio stop enable (EN) option switch is ON, IN8 serves as an audio stop;
AUX08.WAV – even if present – will not play under manual control
Pre-Play and Post-Play Delays
For stand-alone projects the AP-16+ includes potentiometers for setting pre- and post-play delays applied to
