Chapter 1 Overview
1.1 Introduction
The EKI-2741 is designed to convert Gigabit Ethernet networks to Gigabit fiber
networks by transparently converting Ethernet signals to optic signals. The advantages
of fiber optics are wide bandwidth, EMI immunity and long-distance transmission
capability. Therefore, EKI-2741 is an ideal solution for “fiber to building” applications at
central offices or local sites. EKI-2741 supports MDI/MDIX auto detection, so you don’t
need to use crossover wires. Furthermore, the EKI-2741 can work normally from -10 ~
60o C and accepts a wide voltage range from +12 ~ 48 VDC. Besides, it also provides
3,000 VDC surge (EFT) protection against over-voltage, so it is suitable for harsh
operating environments.
1.1.1
Fast Fiber Converters Module
The EKI-2741F/SX/LX provides you with one Fiber connector for your fiber optic cable
and one Ethernet RJ-45 port (Auto MDI/MDIX) for your 1000Base-TX copper cable
connection. There are two DIP-switches to set the operation mode for UTP, Fiber ports
and link loss forwarding function.
1.1.2
Dual Power Input
To reduce the risk of power failure, the EKI-2741F/SX/LX provide +12 ~ 48 VDC dual
power inputs. If there is power failure, EKI-2741F/SX/LX will automatically switch to the
secondary power input.
1.1.3
Flexible Mounting
EKI-2741F/SX/LX are extremely compact 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
The power line of EKI-2741F/SX/LX supports up to 3,000 VDC EFT protection, which
secure equipment against unregulated voltage and make systems safer and more
reliable. Meanwhile, 4,000 VDC ESD protections for Ethernet ports make EKI-
2741F/SX/LX more suitable for harsh environments.
1.1.5
Wide Operating Temperature
The operating temperature of the EKI-2741F/SX/LX is between -40 ~ 75 ℃ (wide
operating temperature model) or -10 ~ 60 ℃ (standard model). With such a wide range,
you can use the EKI-2741F/SX/LX in some of the harshest industrial environments that
exist.
1.1.6
Easy Troubleshooting
LED indicators make troubleshooting quick and easy. The 10/100/1000 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.

Fiber side.
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

2.5 Network Connection
•
Twisted-pair segment can use unshielded twisted pair (UTP) or shielded twisted pair
(STP) cabling. The cable between the link partner (switch, hub, workstation, etc.)
and the converter, must be less than 100 meters (328 ft.) long and comply with the
IEEE 802.3ab 1000Base-T standard for Category 5e or above.
•
•
•
Fiber segment using single-mode connector type must use 9/125 µm single-mode
fiber cable. You can connect two devices in the distance of 10 km.
Fiber segment using multi-mode connector type must use 50/125 or 62.5/125 um
multi-mode fiber cable. You can connect two devices up to 550m distances.
The small form-factor pluggable (SFP) is a compact optical transceiver used in
optical communications for both telecommunication and data communication
applications.
To connect the transceiver and LC cable, please follow the steps shown below:
First, insert the transceiver into the SFP module. Notice that the triangle mark is the bottom of
the module.

Chapter2
Second, insert the fiber cable of LC connector into the transceiver.
Figure 2.10: LC connector to the transceiver
To remove the LC connector from the transceiver, please follow the steps shown below:
First, press the upper side of the LC connector from the transceiver and pull it out to release.

2.6 Power Connection
The EKI-2741F/SX/LX support dual +12 ~ 48 VDC power inputs and power-fail relay
output.
Figure 2.13: Pin Assignment of the Power Connector
You can connect an alarm indicator, buzzer or other signaling equipment through the
relay output. The relay opens if power input 1 or 2 fails ( “Open” means if you connect
relay output with an LED, the light would be off).

Troubleshooting
Chapter 3 Troubleshooting
1.
Power Input
Verify that is using the right power cord/adapter (+12~48 VDC), please don’t use the
power adaptor with DC output voltage higher than 48V, or it will burn this converter
down.
2.
Cable
Select the proper UTP/Fiber cable to construct your network. The single-mode
converter must use single-mode fiber cable. Please check that you are using the right
cable.
3.
DIP Switch
Check the configuration DIP-switch. It must be setting in the same operation mode with
the link partner.
4.
Diagnosing LED Indicators
The switch can be easily monitored through panel indicators, which describes common
problems user may encounter and where user can find possible solutions, to assist in
identifying.
If the power indicator does not light up when the power cord is plugged in, user may
have a problem with power cord. Then check for loose power connections, power
losses or surges at power outlet. If user still cannot resolve the problem, contact the
local dealer for assistance.
If the Industrial switch LED indicators are normal and the connected cables are correct
but the packets still cannot transmit, please check your system’s Ethernet devices
configuration or status.
