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):

Direct Trigger
Non-Interruptible Playback
Closed 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 Direct trigger mode and Non-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)

Trigger Modes (first letter in MODE.TXT)
(D) Direct Trigger (most popular)

In this mode each input directly triggers a corresponding
file: T1 =File 001, T2 = File 002, ... T8 = File 008.
A trigger is valid when the input is shorted to the ground
for at least 50 ms.

(B) Binary Trigger

To trigger a particular file, the first step is to signal the file
number on T1 (LSB) ~ T7 (MSB). and T8 being the data
latch.

(S) Sequential Trigger

Use the Sequential Trigger to sequentially trigger up to 99
different files per input, as defined below:
T1 triggers File 001 ~ 099……….
T8 triggers File 801 ~ 899
Each trigger on the same input activates a different file in
the sequence.

( R) Round-Robin Trigger

This mode is very similar to the Direct Trigger mode
except that the inputs are not prioritized - if multiple
inputs are tied to ground then their files will be played one
after another, instead of just the highest priority one.

Playback Modes (second letter in MODE.TXT)

The Playback Mode defines how the playback is to
proceed. The Playback Mode does not apply when the
system is controlled via the Serial Interface.

(N) Non-interruptible Playback

The file is played once per trigger. The playback is not
interruptible except by the system reset. Looping is
possible by applying a constant trigger on the input.

(I) Interruptible Playback

The file is played once per trigger if not interrupted (can
not interrupt itself unless in DIM mode). The playback
does not start until the trigger is removed (input returns to
+5V.

(H) Holdable Playback
The file is played for as long as the input is triggered,
looping if necessary. It is not interruptible except by the
system reset.

(S) Script Playback

These are the script commands:
Fnnn - play File #nnn
Wnnnnn - wait nnnnn units of 0.1 second
Jnnn - jump to trigger #nnn
BF - turn off the Busy output
BN - turn on the Busy output
XNn - turn on relay #n
XNN - turn on all relays
XFn - turn off relay #n
XFF - turn off all relays
END
More detailed information can be found in the Full User
Manual.

Trigger Type (third letter in MODE.TXT)
( C) Closed ..Keep triggering when contact closed

(O) Open..Trigger when contact opened
(M) Make..Trigger once when closed
(B) Break..Trigger once when opened

RS232 Serial Control

For serial control (RS-232/RS-485), replace the two-letter
word with a two-digit address ranging from “00” to “32”.
This number is used by your PC(or controller) to
communicate with specific TecMP3s.

RS232 Commands

A## (address ##) – send before every command if the
player ID is not 00.

F### (play file ### )
L### (loop file ###)
S (Stop file)
P (Pause file)
R (Resume file)
B (busy enquiry), “b” is busy and “s” is not
XN# (turn on relay #)
XNN (turn on all relays)
XF# (turn off relay #)
XFF (turn off all relays)
