2 System Design
IMPORTANT NOTE: Whist the M3-310 does make it easy to build a media
player based system it is intended for use by qualified system builders and
integrators; the manufacturer accepts no liability for damage or injury caused
by the use of this product. It is the responsibility of the system builder or
integrator using the M3-310 and related parts to:
Ensure that all necessary and appropriate safety measures are taken.
Obtain relevant regulatory approvals.
Check power settings to all component parts before connection.
DISCLAIMER: There is no implied or expressed warranty regarding this
material.
2.1 Familiarization
The M3-310 media player board has a number of accessories, internal
connectors headers, external type connectors and indicator lamps. Before any
system design commences it is important to understand the purpose of all
these and the system options they enable –please review the board itself
together with the notes and relevant tables as detailed throughout this user

3 Connection Overview
CAUTION: Never connect or disconnect parts of the system when the system
is powered up as this may cause serious damage.
3.1 Prepare for connection
Connection and usage are straightforward. However, during assembly, care
needs to be taken regarding the following:
Ensure parts, especially power and signal cables, match the system. If
you are making your own cables & connectors refer carefully to the
video monitor specifications and the “Connectors, Pin outs & Jumpers”
section in this user guide to ensure the correct pin-to-pin wiring.
Ensure cables have been correctly connected and that connections are
secure.
Screws and fasteners need to be secure, consider using locking glue if
appropriate.
Switches and jumpers are set correctly.
The output signal is compatible with display equipment.
Legal & safety requirements have been met with particular attention to
the likely operating environment. Although the M3-310 is designed to
be fanless in normal conditions some installations and environments
may require additional cooling.
3.2 Basic connection for M3-310
The following summarizes a simple connection:
Connect the inverter (if it is not built-in the panel) to the CCFT lead
connector(s) on the panel.
Plug the inverter cable to CNB1 and CNA1.(if necessary) on the M3-310.
Plug another end to the connector on the inverter.
Note: Different inverter models require different cables and different pin
assignment. Make sure correct cable pin out to match inverter. Using wrong
cable pin out may damage the inverter.
Plug the panel signal cable direct to CN2 (if TTL panel is used) or J3 (if
LVDS panel is used) on the M3-310. Plug the other end of cables on the
LCD panel connector.

Page 8 of 36
CAUTION: Before connecting power ensure all parts are suitably
insulated and there is no risk of short circuit or electrocution. Connect
the power supply (DC 12V @ 1.2A minimum. - ensure correct polarity)
to the M3-310 power input (PP1).
Plug the OSD switch mount cable (p/n:420680260-3) to CNC1 on the
M3-310 and another to the OSD switch mount. (P/N:416100520-3)
For “Auto play with Power On”, short the pin1-2 on JP6
Ensure there is a CF card installed with compatible media loaded.
If the optional buttons are being used connect them to CN6 and CN3

4 System Notes
The following outlines various issues related to the M3-310 and making a
complete system:
LED1/LED2 - The power/status LED indicator shows the following
status of Panel:
Controller LED status (LED1): Backlight LED status (LED2):
RS-232 port –This port supports RS-232 communications for control.
The baud rate must be set to (9600, n,8,1) and record suffix is set to
CR (0DH).
USB –Plug an USB extension cable (P/N:426894600-3). Use a USB
flash drive for content update without removing the CF card. The M3-
310 will reset the power when a USB flash drive is inserted or removed
from the USB connector. (For the details of USB content update, please
refer to the Application note.)
Audio output –This provides speaker out and line out connection.
Master volume is controlled through OSD with buttons connecting to
CN6. For connection, plug a stereo speaker (P/N 230800301) with
stereo cable (P/N 426680900-3) to the connector CN1. If for line out
connection, connect an audio line out cable (P/N 426450300-3) to CN9.
Volume control –To control the loudness of internal speaker, a 47K
Volume Rotary (VR) can be used. Plug the VR extension cable
(P/N:426890510-3) on to the jumper VR1.
Jumpers & Inverter & Panel voltage –pay special attention to the
settings of JA3, JB2 & JB3. The JB2 & JB3 are used for inverter control
(read inverter specification and information on the jumper table to
define the correct settings). The JA3 is used for panel voltage input
(read panel specification and information on the jumper table to define
the correct settings).

Power supply - Plug the DC 12V power (ensure correct + & -
orientation) in to the connector PP1. The Digital View mating power
cable is (P/N 426013800-3), 160mm. Please read the jumper table in
Section 5 to define the correct settings. Otherwise it may break down
the panel. (Note: Maximum current output to panel: 2A)
Power on - Switch on the M3-310 board and panel by using the OSD
switch mount (P/N 416100520-3) or short Pin1-2 at JP6 for “Auto power
On”.
Infra-red (IR) - Supports IR control with DV remote control handset
(P/N:559000104-3). The IR sensor and cable kit (P/N:446010401-3)
are required. The IR control functions are shown as below.

Buttons and Touch screen (segment type) –A number of related
accessories are available providing enhanced functionality such as user
buttons and touch screen.
A) Mechanical buttons
Standard MV-switchmount (P/N:416101300-3) for 1-8 buttons
when connected to the button connector CN6 via the standard
switchmount cable (P/N:426451100-3).

Page 11 of 36
Custom made switchmount for 1-16 buttons when connected to
the buttons connector CN6 and CN3 via the standard
switchmount cable (P/N:426451100-3)
B) Touch screen segments
The M3-310 when connected with a LCD interface controller can
output videos on to LCD screen. Button control can be
performed via touch screen for panel sizes of 6.4”, 7”, 8”, 10”,
12”, 15”, 17” and 20”
There is one type of button pattern layouts on the touch screen
available: 8 buttons
(For any special button layout, please contact local sales office.)
Fig. 1 8-buttons for LCD touch screen
C) Button function settings
Whether the buttons are of the mechanical type (on the
standard switchmount or custom made) or the touch screen
segment type, each button function can be programmed with
the DV Studio Software program to perform a VCD player
mode function or specific track select function. (See DV Studio
Software user manual).
The DV Studio Software program is available for free download
from the Digital View website.
Service & Warranty Forfeit: The warranty will be invalid if rework is
performed on the M3-310. The M3-310 is not user serviceable or
repairable.
