For example, a sound file associated with optional contact input #1 would be named “01.WAV,” a sound
file for input #10 would be named “0A.WAV,” a file for input #16 would be “10.WAV” and a file for input
#36 would be “24.WAV”.
There is no input #0 and so “00.WAV” is reserved and should not be used.
There is a maximum of 254 sounds so “FF.WAV” is reserved and should not be used.
The two digit hex input number must be the first two characters in the filename.
Additional letter tokens are appended to the input # in the filename to determine
when
and
how
the audio
sound is played. The
Compact FLASH IV Digital Audio System
provides two inputs in its standard
configuration and, by adding optional boards, can be expanded to 10, 18, 26 or 50 total inputs. The inputs
can be wired to switches or other such devices, either normally opened or normally closed.
You can also connect the RS-232 port of the
Compact FLASH IV Digital Audio System
to the RS-232
port of your computer or PLC to control up to 254 sounds using serial commands.
The filename letter tokens are described as follows:
If a “
C
” appears after the hex number in the filename, the sound file will be played on a
C
losure
of the
corresponding optional contact input module input or serial command. The sound will start playing when the
associated contact input goes from an open to closed state.
If an “
O
” appears after the hex number in the filename, the file is played on an
Opening
of the
corresponding optional contact input module input or serial command. The sound will start when the
associated contact input goes from a closed to an open state.
If a “
P
” after the hex number in the filename, the file will play only while the “
C
” or “
O
” state is true. If
“
C
”
, it will play while the associated contact input is closed and it will stop playing the sound when the input
is opened. If
“
O
”
, it will play while the associated contact input is open and it will stop playing the sound
when the input is closed.
If an “
R
” appears in the filename after the hex number, the sound is
repeated,
that is to say that the same
sound file plays over and over. If used in conjunction with the “
P
” command, the sound file will repeat the
entire time the “
C
” or “
O
” input condition is true. If
“
C
”
, the entire time the input is closed, if
“
O
”
, the
entire time the input is open. If triggered without a
“
P
”
attribute, the file will play indefinitely or until
another sound is played.
If an “
S
” is used in the filename after the hex number, the on-board Push-To-Talk (PTT) relay and
contact closure corresponding to the input number on an optional plug-in board will be activated when the file
is played.
If a “
B
” is used in the filename after the hex number, the sound is considered to be a
background
sound.
Background sounds play when no other sound is playing, and multiple background sounds are played in the
numerical sequence of the two digit input number. Sounds that are marked as Background may not be marked
for contact closure or opening, play while or repeat. Such markings will be ignored.
If an “
N
” is used in the filename after the hex number, the sound is considered to be a
non-interruptible
sound. Sounds that are marked as non-interruptible will play to completion before any other sounds are
played. Contact events that occur while non-interruptible sounds are playing are discarded unless the
SaveNIContacts entry in the optional CFSOUND.INI file [Contacts] section is set to TRUE. Sounds that are
marked as non-interruptible may not be marked for Repeat or as a Background sound. Such markings will be
ignored.
If an
“
F
”
is used in the filename after the hex number, the sound is considered to be associated with a
DMX channel Fade. Sounds that are marked for fade will ramp up the associated DMX channel value
between the
BeginFadeValue
and
EndFadeValue
entries at the
FadeDuration
rate in the CFSOUND.INI
file [DMX] section when the sound plays and ramp down when the sound ends or another sound is started.
