Product Warranty (5 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for five years from the date of pur-
chase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defec-
tive, it will be repaired or replaced at no charge during the warranty period. For out of-
warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any on screen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandize
authorization) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completedRepair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales receipt)
in a shippable container. A product returned without proof of the purchase date
is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package and ship it prepaid
to your dealer.

Safety Instructions
Read these safety instructions carefully.
Keep this User Manual for later reference.
Disconnect this equipment from any DC outlet before cleaning. Use a damp
cloth. Do not use liquid or spray detergents for cleaning.
For plug-in equipment, the power outlet socket must be located near the equip-
ment and must be easily accessible.
Keep this equipment away from humidity.
Put this equipment on a reliable surface during installation. Dropping it or letting
it fall may cause damage.
The openings on the enclosure are for air convection. Protect the equipment
from overheating. DO NOT COVER THE OPENINGS.
Make sure the voltage of the power source is correct before connecting the
equipment to the power outlet.
Position the power cord so that people cannot step on it. Do not place anything
over the power cord.
All cautions and warnings on the equipment should be noted.
If the equipment is not used for a long time, disconnect it from the power source
to avoid damage by transient overvoltage.
Never pour any liquid into an opening. This may cause fire or electrical shock.
Never open the equipment. For safety reasons, the equipment should be
opened only by qualified service personnel.
If one of the following situations arises, get the equipment checked by service
personnel:
–The power cord or plug is damaged.
–Liquid has penetrated into the equipment.
–The equipment has been exposed to moisture.
–The equipment does not work well, or you cannot get it to work according to
the user's manual.
–The equipment has been dropped and damaged.
–The equipment has obvious signs of breakage.
DO NOT LEAVE THIS EQUIPMENT IN AN ENVIRONMENT WHERE THE
STORAGE TEMPERATURE MAY GO -40°C (-40°F) ~ 85°C (185°F). THIS
COULD DAMAGE THE EQUIPMENT. THE EQUIPMENT SHOULD BE IN A
CONTROLLED ENVIRONMENT.
The sound pressure level at the operator's position according to IEC 704-1:1982
is no more than 70 dB (A).

Safety Precaution - Static Electricity
Static electricity can cause bodily harm or damage electronic devices. To avoid dam-
age, keep static-sensitive devices in the static-protective packaging until the installa-
tion period. The following guidelines are also recommended:
Wear a grounded wrist or ankle strap and use gloves to prevent direct contact to
the device before servicing the device. Avoid nylon gloves or work clothes,
which tend to build up a charge.
Always disconnect the power from the device before servicing it.
Before plugging a cable into any port, discharge the voltage stored on the cable
by touching the electrical contacts to the ground surface.

EKI-1500 Series User Manual 2
1.1 Overview
The EKI-1500 Series are network-based serial device servers that connect RS-232/
422/485 serial devices, such as PLC, meters, sensors, and barcode readers, directly
to a TCP/IP network.
Once connected through a EKI-1500 Series serial server, devices are able to send
and receive data through a network. This extends the traditional COM ports of a PC,
with access over a TCP/IP network. Through networking, you can control and moni-
tor remote serial devices over either a LAN or WAN. Since the EKI-1500 Series is
connected through a TCP/IP network, you may need to know some basic facts about
networking in order to connect the server correctly.
The EKI-1500 Series features two independent Ethernet ports and MAC addresses
to provide a redundant network mechanism to avoid data loss. The EKI-1500 Series
provides various operations: COM port redirection mode (Virtual COM Port mode),
TCP Server/ Client mode, UDP mode, Control mode and RFC2217 mode. Detailed
descriptions of each operation are provided in a later chapter.
1.2 Device Features
Provides 2 x 10/100 Mbps Ethernet ports for LAN redundancy
Provides COM port redirection (Virtual COM), TCP and UDP operation modes
Supports up to 921.6 kbps, and any baud rate setting
Allows a max. of 5 hosts to access one serial port
Allows a max. of 16 hosts to be accessed as TCP client mode
Built-in 15 KV ESD protection for all serial signals
Provides rich configuration access, including: Windows utility, Telnet console,
and Web Browser
Supports 32-bit/64-bit Windows 2000/XP/Vista/7/8/8.1/10, Windows Server
2003/2008/2012, and Linux
Automatic RS-485 data flow control
Supports surge protection for D.C. power ports with line to line 2 KV, and line to
earth 4 KV; for signal ports with 4 KV.
Supports a wide operating temperature (I models only)
Supports isolation and wide operating temperature (CI models only)
