Glossary
A
acknowledge.
A serial port command or a dry contact input which will cause a message file of priority level 4 or 5 that is
continuously activated to stop repeating after having played at least once.
activation.
An input that causes a file to be selected and processed.
C
channel.
An audio output path through which the digital voice module transmits message files to the audio system. Each digital
voice module can have up to four channels.
D
DX-100.
Playback only digital voice module described in this manual.
DX-200.
Record/playback digital voice module described in this manual.
DV-EM.
Digital Voice Expansion Module, 32 file input selections per module.
E
EPROM
. Erasable Programmable Read Only Memory. Non-volatile semiconductor memory used to store messages in the DX-100
and the program in the DX-100 and DX-200.
F
file.
Digital voice module files are created either by storing audio directly into a selected file number or by storing the numbers of
other files that contain audio into the selected file number. Every file is assigned an output channel and a priority level. Up to 999
files can be created in the digital voice module. A file becomes a message file if it is selected to be played by a contact closure or by
a command through the serial port. Some files are never intended to become message files; they merely contain words or phrases
that can be strung together to create new files that will become message files. The new files will be assigned channel and priority
designations that supersede previous channel and priority designations for the individual files in the new string.
M
message.
An audio output generated and played through an assigned channel when a file number is selected by a contact closure
or command on the serial port.
P
priority.
The order by which files are designated to be played. All files are assigned a priority from 1 to 5, with 1 as the highest
priority.
PSRAM.
Pseudo Static Random Access Memory. Volatile semiconductor memory used to store DV-200 messages.
Q
queue.
A sequence of message files that have been selected to be played through a particular channel. Each file is positioned
according to its pre-assigned priority. Equal priority files are positioned in the order they were selected. A file cannot be included in
this queue more than once. However, after a file has completed playing, it can be re-added to the queue.
R
reset.
A serial port command or a dry contact input which will cause the file presently playing to stop immediately and remove all
files from the queue.
S
string.
A combination of file numbers (with optional delay or repeat commands) stored in a file and arranged to form a desired
message.
