1. Introduction
System Overview
The MP3-WS is a simple MP3 playback device with a status output suitable for driving an LED or other low
voltage device. The MP3-WS requires a low voltage power supply (12vdc –24vdc). The player has a
sturdy aluminum case with mounting tabs. An internal 40W class D amp is available as an option.
Document Overview
The following terminology appears throughout this manual.
Ground, negative, or (-) may be used interchangeably when referring to the power supply connections.

3. Hardware
Power Supply
The MP3-WS will operate on 12 to 24 volts DC.
Connect the power supply to the terminals in the PWR
section marked: +& -
If the optional amplifier is installed, A 24-volt 2.5-amp
power supply is required to produce the full 40 watts
of power. If you intend to use the same supply for
powering output devices (valves, relays, etc)
additional amperage is required.
There are two extra +terminals for convenience on
the output connector. The +terminals are internally
connected. This provides extra terminals to attach
other items requiring power.
Warning: The +terminal in the Triggers section of
the connector is not the same as the +terminals in
the PWR section.
The +terminal in the Triggers section is a 12vdc output from the MP3-WS’s internal 12v regulator. This
can be used to supply triggers that require power.
Output
The output is driven by a 1amp solid state driver.
The +terminal carries the same voltage found at the PWR +
terminals.
This output is on any time an audio file is playing
The MP3-WS output switches the negative side of the voltage
Note: Flyback Diodes should be installed across inductive loads
like solenoid valves.

Trigger Input
The trigger input on the MP3-WS can accept a variety of trigger
devices; voltage sourcing or contact closure. A normally open
contact is required.
Every time a trigger pulse is received, a random audio track will play.
All of the tracks in the play list will play once before the list is shuffled.
Warning: the + terminal in the Trig section is a special 12v out
terminal to provide voltage to trigger devices requiring 12 volts.
Do Not apply external voltage to this terminal.
Speakers
The MP3-WS has an optional mono 40-Watt amplifier. This amp is
connected to the left channel of the MP3 player. If installed, connect
speaker(s) to the + & - terminals with a minimum of 4 ohms total.
LCD Display
The integrated color LCD display shows the number of audio
clips loaded and the last clip played.

4. Software Operation
The computer interface provides tools that enable you to create an audio library for the MP3-WS. It is not
possible to retrieve audio clips back out of the MP3-WS.
Software Installation
The installation package consists of a single file
•Interface Utility Setup.exe
Double Click setup.exe to begin the installation.
When the Welcome screen appears, click the
Next > button.
7
Click Install.
When the setup completes, click Finish
The Interface Utility will appear on your start menu in the
HauntBots folder
8
Driver Installation
When you initially plug the MP3-WS into your computer, Windows will attempt to load an appropriate driver.
If an MP3-WS or other HauntBots controller has not previously been installed, you will need to manually
load the driver.
The exact screens will vary a bit
between different versions of
Windows. The MP3-WS will be
recognized by Windows as CCS
USB to UART rather than
HauntBots MP3-WS. These
instructions cover an install on
Windows 7.
After the computer reports
that the driver was not
successfully installed, go
to device manager to
install it manually.
Click the Windows Start Button, right click on Computer then
scroll down and click Properties.
Click Device Manager in the top left column.
9
In device manager look in Other Devices for the CCS
USB to UART device with the yellow exclamation point.
Right click on CCS USB to UART and choose Properties
Click the Update Driver button
10
Click Browse my computer for driver
software.
In the Browse for Folder window go to
C:\Program Files(x86)\HauntBots. Select
the USB Driver folder then click the OK button
Click the Next button.
