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 onscreen 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

Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from damage.
1. To avoid electrical shock, always disconnect the power from your PC chassis before you
work on it. Don't touch any components on the CPU card or other cards while the PC is
on.
2. Disconnect power before making any configuration changes. The sudden rush of power
as you connect a jumper or install a card may damage sensitive electronic components.

Chapter 1 Overview
1.1 Introduction
The EKI-2541M/2541S is a cost-effective solution for the converting between
10/100Base-TX and 100Base-FX cabling, it allows you to extend the cabling distance
of your 100Base-FX network up to 2 kilometers for multi-mode fiber or 30 kilometers
for single-mode fiber. The Fast Fiber Converter module gives you the option to choose
from the most popular fiber cabling connectors: SC multi-mode and single-mode
connector.
1.1.1 Fast Fiber Converters Module
The EKI-2541M/2541S provides you with one Fiber connector for your fiber optic cable
and one Ethernet RJ-45 port (Auto MDI/MDIX) for your 100Base-TX copper cable
connection. There are four DIP-switches to set the operation mode for UTP, Fiber ports
and Link Fault Pass-Through function.
1.1.2 Dual Power Input
EKI-2541M/2541S redundant power input design is with power reserve protection to
prevent the switch device broken by wrong power wiring. When one of power input is
fail, P-Fail LED will turn on and send an alarm through a relay output for notifying user.
1.1.3 Flexible Mounting
EKI-2541M/2541S is extremely compact (30x 140 x 95 mm) and can be mounted on a
DIN-rail or a panel, so it is suitable for any space-constrained environment.
1.1.4 Advanced Protection
EKI-2541M/2541S supports up to 3,000 VDC surge protection for power line, and also
supports 4000V ESD for Ethernet ports. With these 2 strong protections, it can secure
equipment against unregulated voltage and make systems safer and more reliable.
Further, EKI-2541M/2541S provides currency overload protection with a resettable
fuse to ensure that the device component won’t be damaged by overload current.
1.1.5 Wide Operating Temperature
The operating temperature of the EKI-2541M/2541S is between -40 ~ 75 ℃(wide
operating temperature model) or -10 ~ 60 ℃(standard model). With such a wide range,
you can use the EKI-2541M/2541S in some of the harshest industrial environments
that exist.
1.1.6 Easy Troubleshooting
LED indicators make troubleshooting quick and easy. The 10/100 Base-TX port has 2
LEDs that display the link status, transmission speed and collision status. Also the
three power indicators P1, P2 and P-Fail help you diagnose immediately.

2.2 DIP-Switch
The DIP-Switch is used to configure operation mode for LFP (Link Fault Pass-
Through) and operation mode for UTP/Fiber port. The default value of DIP-switch is
OFF.
Table 2.2: EKI-2541M/S DIP-Switch Definition
S/W No Status Description
ON Enables Port/Power Alarm
1
OFF Disable Port/Power Alarm
ON Enables LFP
2
OFF Disables LFP
ON 100Base-FX Half-mode
3
OFF 100Base-FX Full-mode
ON Pure Converter mode (100TX to 100FX)
4
OFF Switch Converter mode
LFP (Link Fault Pass-Through): When LFP is enabled, it allows UTP link failures to
be reported to the fiber side and also allows Fiber link failures to be reported to the
UTP side. Therefore, an LFP feature is provided in both UTP and Fiber side.
Pure Converter mode (DIP-Switch 4): When pure converter mode is enabled (on), it
operates with the minimum latency. The transmission flow does not wait until entire
frame is ready, but instead it forwards the received data immediately after the data
being received. And UTP port should be forced at 100M in this application. When DIP-
Switch is in Switch Converter mode (off), the converter function is same as Switch
Note Please don’t change the DIP-switch setting when UTP or fiber port is
transmitting or receiving data. It may cause some data error. Besides, if you
change the DIP-switch setting, please power off the converter and power on
again to make the setting effective.
