1.4 Safety
SECO104-CX700M module uses only extremely-low voltages.
While handling the board, it is necessary to be careful in order to avoid any kind of risk or damages
to electronic components. Always switch the power off, and unplug the power supply unit, before
handling the board and/or connecting cables or other boards.
Don’t use metallic components, like paper clips, screws and similar, near the board, when this is
supplied, to avoid short circuits due to unwanted contacts with other components of the board.
Never connect the board to an external power supply unit or battery, if the board has become wet.
Make sure that all cables are correctly connected and are not damaged.
1.5 Electrostatic Discharges
SECO104-CX700M, like any other electronic product, is an electrostatic sensitive device and some
components on-board could be damaged by high voltages caused by static electricity.
So whenever handling a SECO104-CX700M board, take care to ground yourself through an anti-
static wrist strap. Placement of the board on an anti-static surface is also highly recommended.
1.6 RoHS compliance
SECO104-CX700M board is designed using RoHS compliant components and is manufactured on
a lead-free production line. It is therefore fully RoHS compliant.

2.3 Electrical specifications
2.3.1 Power Connector
SECO104-CX700M is powered through the dedicated connector CN15, which is a 5-pin 2.54mm
pitch male connector, type PHOENIX CONTACT MC0.5/5G-2.5. Refer to the following table for the
pin assignment.

It’s strictly recommended, if external –12VDC is not needed, to use pin 2 for a second
connection to +5VDC power supply.
Furthermore, it’s better to use cables of minimal length (the minimum required for intended
applications, possibly not more than 20-25 cm), using separate wires for each GND and
+5VDC voltages.
It’s also recommended the use of wires with a cross section of 0.5mm2(AWG20, maximum
section allowed by the connector).
SECO104-CX700M requires only an external +5VDC and generates all the other voltages internally,
through a supply module mounted vertically on the two dedicated connectors.
+12VDC is internally used only to produce a switched supply voltage for inverter units for flat panels’
lamps; this is switched by a MOSFET driven by the graphic controller, allowing to turn on and off
the inverter unit.
If SECO104-CX700M board has to be used with PC/104+ expansion boards, is recommended
to power the board via PC/104+ pins, because these pins are capable of supplying greater
currents. Since using expansion boards increases sensibly power consumptions, this
solution has to be preferred, is possible.
2.3.2 RTC Battery
A 3.3V Rechargeable Lithium Battery supplies the Real Time Clock (RTC), which is built-in in the
VIA CX700MTM Chipset
The battery used is a Panasonic ML1220/F1A Battery, with a capacity of 17mAh. This battery can
grant the charge duration for a period of 2 months in total lack of power supply.
These new batteries are factory charged for first time during functional tests, and are sent to
customers already charged.
However, exactly like for all handheld devices provided with rechargeable batteries, we
recommend that all customers, during first installation of SECO104-CX700M boards, keep the
boards supplied for at least 12 hours, in order to restore battery’s optimal conditions”.
In case the internal battery is not working, or you think its characteristics are not suited for your
applications, you can use pin 1 of UTIL connector (CN9) to connect an external 3V backup battery.
Remember the board does not provide recharge circuitry for this external battery.

Batteries supplied with SECO104-CX700M board are compliant to requirements of European
Directive 2006/66/EC regarding batteries and accumulators. When putting out of order SECO104-
CX700M board, remove the batteries from the board in order to collect and dispose them
according to the requirement of the same European Directive above mentioned. Even when
replacing the batteries, the disposal has to be made according to these requirements.
2.4 Mechanical specifications
According to PC/104-Plus Standard specifications, board dimensions are 90 x 96 mm (3.6” x 3.8”).
The printed circuit of the board is made of ten layers; some of them are ground planes, for
disturbance rejection.

3.3.2 LVDS Channels Connectors
CN2 and CN3 connectors report each four LVDS differential couples from the two internal
channels of the CX700MTM graphic interface. CN2 makes also available the supply voltage for the
LCD panel (VCCLCD) and for the backlight inverter module (VBACKLIGHT), driven both by the graphic
controller. First channel, available on CN2 connector, has to be used for connection of standard 18
or 24 bit TFT displays. VCCLCD voltage can be set at the value of +5VDC or +3.3VDC, using jumper
JP1 (see paragraph 3.3.17). VBACKLIGHT is fixed at +12VDC.
Second channel has to be used only for connection of 18 or 24 bit dual pixel/clock displays (in this
case it is necessary to use both connectors).
CN2 is a single row, 15 pin, male, straight, P1.25 connector, type MOLEX 53047-1510 or
equivalent.
CN3 is a single row, 12 pin, male, straight, P1.25 connector, type MOLEX 53047-0310 or
