Introduction
Thank you for choosing the LEC-7950. The LEC-7950 is a
compact embedded system featuring Intel i3 or Celeron
processors. The system equips with three video output
interfaces: DVI-D, HDMI and VGA. In addition, it also
supports dual RCA ports for both line-in and line-out left
and right connection.
The LEC-7950 answers the demand for versatile I/O
interfaces by offering the following functions:
Supporting the latest memory technology with 2 DDR3 •
SO-DIMM sockets for a maximum capacity of 16GB
Audio and video displays powered by Realtek ALC886- •
GR and Intel HD Graphics Engine respectively
Two 10/100/1000 Mbps LAN •
USB x 6 (2 by internal pin header) and COM x 2 •
1 hard disk bay for 2.5" SATA/SSD installation •
Totally 4 serial ports: Two of them are DB9 connector •
type and support hardware auto flow control with
jumper settings to switch among RS232/422/485; the
other two are provided via pin headers and support
only RS-232
Dual Mini-PCIe Socket (One of them comes with a SIM •
card reader for 3G wireless Internet connection.) to
extend the capability for Wi-Fi or Bluetooth
Supporting distant power-on switch through terminal •

The controller contains two modes of operation—a
legacy mode using I/O space, and an AHCI mode using
memory space. Software that uses legacy mode will not
have AHCI capabilities.
The AHCI ( Advanced Host Controller Interface) is a
programming interface which defines transactions
between the SATA controller and software and enables
advanced performance and usability with SATA. Platforms
supporting AHCI may take advantage of performance
features such as no master/slave designation for SATA
devices—each device is treated as a master—and
hardware assisted native command queuing. AHCI also
provides usability enhancements such as Hot-Plug.

then move the cap back to pins 1-2.
Use the BIOS menu to configure your hard disk
to be AHCI compatible.

Chapter 4: Hardware Setup
Preparing the Hardware Installation
To access some components and perform certain service
procedures, you must perform the following procedures
first.
WARNING: To reduce the risk of personal injury,
electric shock, or damage to the equipment,
remove the power cord to remove power from the
server. The front panel Power On/Standby button
does not completely shut off system power.
Portions of the power supply and some internal
circuitry remain active until AC power is removed.
Unpower the LEC-7950 and remove the power cord.1.
Unscrew the 4 rubber feet from the bottom cover of 2.
the LEC-7950 System.
Open the cover.3.
Note:
The motherboards can support up to 16 GB 1.
memory capacity in maximum.
The system supports DDR3 2.
1066/1333/1600MHz SO-DIMM. Do not install
memory module with different specifications.

Note: In order to take off the bottom cover, you will
also need to take off the CF/SIM card protection
cover first.
Installing the System Memory
The motherboard supports DDR3 memory to meet the
higher bandwidth requirement of the latest operating
system and Internet applications. It comes with two
double data rate type three (DDR3) small outline dual inline memory module (SO-DIMM) sockets.

Hardware Setup
Installing the Hard Disk
The system can accommodate one Serial-ATA disks. Follow
these steps to install a hard disk into the LEC-7950:
Take off the HDD tray from the chassis cover.1.
Secure the hard disk with 4 mounting screws on the 2.
HDD tray.
Place hard disk back on the system and align the holes 3.
of the hard disk with the mounting holes of the chassis
cover.
Connect the Serial-ATA power and data cables to the 4.
hard disk’s connectors.
Plug the Serial-ATA cables (power and data) to the 5.
Serial-ATA Connectors on the main board.

Installing the CompactFlash Card
LEC-7950 provides one CompactFlash slot and it can be
accessed by taking off the front CF/SIM cover. Follow the
procedures bellow for installing a CompactFlash card.
Align CompactFlash card and the card slot with the 1.
arrow pointing toward the connector.
Push the card to insert into the connector.2.

Wall Mounting
The product ships with wall mounting kit. To mount your
product on the wall, follow the instructions below:
First make a hole for the anchor in the surface on the 1.
wall.
Then press the anchor into the hole until it is flush with 2.
the surface. You may need a hammer to tap the wall
anchor.
Use a screwdriver to screw the threaded screw into the 3.
plastic anchor.
Attach the wall mounting bracket to the back of the 4.
device, securing it in place with four of the flat-head
screws provided.
Hang the device on the wall.5.

Appendix A
Programming Watchdog Timer
Appendix A: Programming Watchdog Timer
A watchdog timer is a piece of hardware that can be
used to automatically detect system anomalies and reset
the processor in case there are any problems. Generally
speaking, a watchdog timer is based on a counter that
counts down from an initial value to zero. The software
selects the counter’s initial value and periodically restarts
it. Should the counter reach zero before the software
restarts it, the software is presumed to be malfunctioning
and the processor’s reset signal is asserted. Thus, the
processor will be restarted as if a human operator had
cycled the power.
For sample watchdog code, see Watch dog and DIO folder
in the Driver and Manual CD
Click the Setup program.1.
The welcome screen appears. Click Next to proceed.2.
Driver Installation
Before you could access or control the operation of the
watchdog and Digital I/O functions, install the the L_IO
driver which is the library and driver needed for Lanner
General Purpose Input/Output interface or functions.
To install the L_IO driver:
Restart the computer, and then log on with 1.
Administrator privilege.
Insert the Drivers and User’s Manual CD to the USB-2.
optical drive.
Browse the contents of the support CD to locate the 3.
file LannerIO v101.rar under the \WD_DIO\ folder and
unzip the file.
Click the Setup program in the unzipped folder.4.
The installation process proceeds. Click Close when the 3.
process completes.
