MAJOR COMPONENTS OF THE MOD BOX
Figures 1-5 and 1-6 show the major components of the MoD BoX Jukebox. Take a
minute to familiarize yourself with these components.
Core Computer
The Core Computer is the heart of the system and has a removable hard drive and a single
board computer. The hard drive is the only storage in the system and retains: Windows XP
Embedded Operating System software, all Application software, all music, and all setup and
audit data. The single board computer converts music selections stored on the hard drive
into a stereo signal for the systems audio components. It also connects to the Internet, the
SVGA touch screen monitor, and to the other peripherals through the Communication Con-
troller.
Touch Screen 15" LCD Monitor
All viewing, displaying, selecting, or entering is done through the Touch Screen Monitor. Some
of the things it is used for are: viewing and making selections, displaying the selection play-
ing, displaying pricing and credits, viewing and changing setup and audit data, and down-
loading “Music On Demand” selections.
System Power Supply
The system power supply produces +9 VDC, +12 VDC, +24 VDC, and has a relay to turn on/
off the jukebox lights, touch screen monitor, and bill acceptor. It has an IEC 320 power inlet,
two 6A circuit breakers, two 4A fuses, and a power switch for service/repair of the jukeboxes
parts. The power switch removes power from all components except the Core Computer and
the Router.
Transformer Assembly
Supplies power for the 250 Watt Digital Audio Amplifier and preamplifier, plus the system’s
DC power supply voltages +9 VDC, +12 VDC, and + 24 VDC.
Communication Controller
Connects the Core Computer serial RS-232 COM1 port to the serial RS-485 modules. This
also includes the coin switch interface. Provides push buttons for service mode, touch screen
calibration, and rejecting a song.
Router
This device provides the interface between the Core Computer and the broadband modem or
satellite receiver. There is a one time configuration process to set this device for your
particular Internet Service Provider (ISP). In addition to the port required for the Core
Computer, there are three other ports provided for other devices.
Switch and Volume Control
This unit controls the main power to the jukebox. It contains the Selection Reject Switch, the
Volume Control Switch, the core computer’s reset switch, the router reset switch and the ON-
OFF switch. This switch controls the power to the lights and touch screen. The amplifier,
router and core computer are unaffected.
