1. About the EMC-LAN-EX LAN Extender
1.1 Description
The LAN-EX transmits high-speed Ethernet over long distances on STP (Shielded
Twisted Pair) which is particularly relevant for elevator hoistways which are electrically
“noisy” (both electrostatic and electromagnetic) compared to standard LAN Extenders
requiring unshielded wiring which would be significantly more susceptible to noise.
The basic LAN-EX modem operates in pairs in bridge mode, each with one J45
Ethernet port and one J45 (2-wire) VDSL port transmitting up to 100Mbps of
symmetric data over copper wires. Symmetrical or asymmetrical transmission can be
selected with bandwidth up to 100/100 Mbps (line rate) within 1,000’ (~300m) or
10/10 Mbps for 3,000’ (~900m) connections. Gbps models are available wherever more
bandwidth is required.
One-way or even two-way video streaming and telephone voice can be multiplexed to
share the same pair of wires although, if available, separate pairs reduce
troubleshooting complications.
In summary the LAN-EX provides a reliable, cost-effective method to deliver Ethernet to
an elevator over standard traveling cable shielded twisted pairs.
1.2 Key Features
 Cost-effective long-distance Ethernet bridge
 Asymmetric mode provides the highest line rate with directional control via DIP
switch
 Symmetric mode provides up and down transmission as would be required for a
camera and a media player
 Supports “flow control” with Pause Frame or Back Pressure
 Selectable profiles are available for maximum data rate to suit different
requirements, for example less error checking and high or lower signal to noise
ratio (SN ).
 19-inch rack mountable (2U)
 Ease of setup and operation
 LEDs for diagnostics

2. Description of Operation:
Select the settings on the DIP switches to suit the operation required:
 Asynchronous for media player only (faster in one direction)
 Synchronous for media player and camera
 Select the profile (DSL mode) for the highest data rate or longest distance
 Select the SN (Signal:Noise) to suit the application
and turn on the power.
The modules will connect and LEDs illuminate according to the settings. The
LNK (link) LEDs will start slow on-off then begin to flicker fast to indicate data flow.

3. Circuit Board Layout & Connections
3.1 Front Panel
Front panel can be separated into five parts from left to right:
 DIP switch (head-end or field/profile/uni- or bi-directional/signal:noise)
 J45 connector for Ethernet (LAN)
 LEDs for LAN (left-hand column)
 LEDs for VDSL (Very high-speed Digital Subscriber Line)
 J45 connector for single pair VDSL
The DIP Switch selects:
Pin 1 Pin 2 Pin 3 Pin 4
Head/Field Profile Direction SNR
Off OT (Head) High throughput Symmetric 9dB
On T (Field) Long each Asymmetric 6dB
3.2 LED activity if operating correctly:

7. Precautions
Always follow basic safety precautions when using your communications equipment to reduce
the risk of fire, electrical shock and injury.
1. ead and understand all instructions in the User Guide.
2. ead all warnings and follow all instructions.
3. Do not use liquid or aerosol cleaners.
4. Do not use the devices if exposed to water or located in a wet environment.
5. Use only the type of power source supplied by the manufacturer or specified in these
instructions (must be current-limited to class 2). If you are not sure of the type of
substitute power supply, consult your dealer or the manufacturer.
6. Never spill liquid on the equipment.
7. Do not disassemble this product unless qualified to do so. Opening or removing covers
may expose you to dangerous voltages or other risks. Incorrect reassembly can cause
electrical shock.
8. Do not overload outlets and extension cords if connecting to AC power from an outlet.
Overloading the outlets can result in fire or electric shock.
9. Notify a building official if:
• Liquid has been spilled into the equipment
• The equipment has been exposed to rain or water
• The equipment exhibits a smell or distinct change in performance.
CAUTION – Always disconnect the power supply and communications connections
from the source before servicing this equipment
10. Save these instructions
