Introduction
Introduction
Thank you for choosing the LEC-6020. The LEC-6020
series is an industrial cyber security appliance featuring a
different number of serial communication ports as well
as Ethernet ports in a compact frame design (65mm(W)
x146mm(H) x127mm(D)).
The LEC-6020 has an innovative industrial and mechanical
design. It can be placed on desk or mounted on dinrails. This reduces maintenance effort when the device
is installed in an industrial setting where access is not
convenient.
The LEC-6020 also features a solid and sealed aluminum
extrusion framing.
Here is the summary of the key capabilities of LEC6020:
Onboard Intel Atom N2600 with Intel NM10 chipset •
4 serial ports (on model A only) and one serial port •
(on model C, D)
Two, five or seven gigabit Ethernet RJ-45 or optical •
fiber ports (all ports have magnetic isolation protection
of 1.5 KV). Moreover, these ports are capable of LAN
bypass, supporting dynamic disconnection/bypass
on a host system failure, power off or upon software
request.
Two or four USB ports depending on the model •
number
Power input via Phoenix contact with power failure •
relay (B, C, D only)
Please refer to the following chart for a detailed description
of the system's specifications.

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. Portions of the power supply and some
internal circuitry remain active until power is
removed.
Unpower the LEC-6020 and remove the power cord.1.
The top cover has an L shape. Unscrew the threaded 2.
screw one the back near the din-rail and the screws on
the two sides as show in the picture.
Slide the cover backwards to open the cover.3.
Installing the System Memory
The motherboard supports DDR3 memory that features
data transfer rates of 1066/1333 MHz to meet the higher
bandwidth requirements of the latest operating system
and Internet applications. It comes with one Double Data
Rate 3 (DDR3) Small Outline Dual In-line Memory Module
(SO-DIMM) socket.
Align the memory module’s key with the SO-DIMM 1.
socket’s key.
Install the SO-DIMM.2.
Note:
SO-DIMMs installed should meet the required 1.
speed which is 1066/1333 MHz. Do not install SODIMM supporting different speeds.
The motherboards can support up to 2 GB 2.
memory capacity in maximum.

Introduction
Installing a CompactFlash Card
LEC-6020 provides one CompactFlash slot. Follow the
procedures bellow to install a CompactFlash card.
Unscrew the screws on the side to take out the cover.1.
Align CompactFlash and the card slot with the arrow 2.
on the CompactFlash pointing toward the connector.
Insert the CompactFlash into the connector.3.
Close the cover and fasten it with the screws to the 4.
slot.
1
Connecting Power
Connect the LEC-6020 to a 12~36 VDC power source. The
power source comes from the AC/DC Adapter through a
Phoenix contact. This power socket is specially designed
to guard against fault in power contact, i.e., the reverse of
the electrical polarity will not damage the system.
-DC in +
- +
- +P-fail

Note: The device has an error proof design so that
the card will not be inserted if it is in the wrong
orientation. You should insert the CF card with the
arrow on the CompactFlash facing up and pointing
toward the connector.

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 WD folder under Driver
and Utility on the Driver and Manual CD
