Descriptions of the connectors
Parallel Interface Terminals: T1 - T8
Audio files can be TRIGGERED by grounding these
using a button or motion sensor.
System Reset Terminal: RS
Short terminal RS to the ground to reset the board.
Minimum reset duration is 100 ms.
Busy Output Terminal: BY
This output is taken from a transistor’s collector and
internally pulled up to +5V through a 10K resistor (R11).
Power Input Terminals: G and V+
Connect the power supply’s GROUND to terminal G, and
the POSITIVE output to terminal V+.
Line Output (LINE): 1/8” Stereo Phone Jack
This jack provides single ended line output for external
amplification (TIP-L, RING-R, SLEEVE-GROUND).
Speaker Output Terminals: LF (left channel) & RT
(right channel).
The speaker outputs are single ended (unbalanced).
Serial Interface Connector: DB9 Female
RS232 is 9600,8,N,1 with pin 3 as the RS232 INPUT to
the TecMP3. Pin2 is the transmit and 5 is the GROUND.
Setup of the CompactFlash card.
The Compact Flash card should have nothing on it
except for the MP3 files and the MODE.TXT file.
Typically, each MB of memory should hold a
minute of audio. DO NOT USE LEXAR CARDS
File Number Assignment
The filename must always start with a 3 numbers ranging
from 001 to 999. For example “start.mp3” has to be
renamed “001start.mp3”. This will be file 1 on the system.
The typical contents of the CF card would be:
001_file1.mp3
002_sample2.mp3
003_audio3.mp3
004_playback.mp3
MODE.TXT
The Configuration mode File (MODE.TXT)
By default, the system works in the following mode
(DNC):
D
irect Trigger
N
on-Interruptible Playback
C
losed trigger activation.
To operate the system in other modes, you need to create
an ASCII text file named
“MODE”
with one of the
following two-letter words on the first line: (where the
first character is the trigger mode and the second character
is the playback mode. A option third letter is the trigger
type – C,O,M or B.
For example:
DN is
D
irect trigger mode and
N
on-interruptible. Other
commands are:
DI (Direct, Interruptible)
DH (Direct, Holdable)
DS (Direct, Script)
BN (Binary, Non-interruptible)
BI (Binary, Interruptible)
BH (Binary, Holdable)
BS (Binary, Script)
SN (Sequential, Non-interruptible)
SI (Sequential, Interruptible)
SH (Sequential, Holdable)
RN (Round-Robin, Non-interruptible)
RS (Round-Robin, Script)
