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
> 1 hour except for the MP3 files and the MODE.TXT file.
Typically, each MB of memory should hold a
10 ~ 32 VDC
150 mA minute of audio. DO NOT USE LEXAR CARDS
RS-232 / RS-485

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)
