Overview
Introduction
The SP373HS Industrial 10/100Base TX to 100BaseFX Media
Converter 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 30 kilometers for
single-mode fiber (SC connector).
Fast Fiber Converters Module
The Industrial 10/100Base TX to 100BaseFX Media Converter 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 loss forwarding function.
Dual Power Input
To reduce the risk of power failure, the Industrial 10/100Base TX to
100BaseFX Media Converter provides +12 ~ 48 VDC dual power inputs.
If there is power failure, Industrial 10/100Base TX to 100BaseFX Media
Converter will automatically switch to the secondary power input.
Flexible Mounting
Industrial 10/100Base TX to 100BaseFX Media Converter is extremely
compact and can be mounted on a DIN-rail or a panel, so it is suitable
for any space-constrained environment.
Advanced Protection
The power line of Industrial 10/100Base TX to 100BaseFX Media
Converter supports up to 3,000 VDC EFT protection, which secure
equipment against unregulated voltage and make systems safer and
more reliable. Meanwhile, 6,000 VDC ESD protections for Ethernet ports
make Industrial 10/100Base TX to 100BaseFX Media Converter more
suitable for harsh environments.

Converter is equipped one terminal block connector of two DC power
inputs.
Top Panel of SP373HS 10/100Base TX to 100BaseFX Industrial Media Converter
Wiring the Power Inputs
Please follow the steps below to insert the power wire.
Insert the positive and negative wires into the V+ and V- contacts on the
terminal block connector.
Tighten the wire-clamp screws for preventing the wires from loosing.
6

Wiring the Fault Alarm Contact
The fault alarm contact is in the middle of terminal block connector as the
picture shows below. Inserting the wires, it will detect the fault status
including power failure/port link failure and form an open circuit.
Insert the wires into the fault alarm contact.
Note The wire gauge for the terminal block should be in the range
between 12~ 24 AWG.
LED Indicators
There are few LEDs, which display the power status and network status,
located on the front panel of the Industrial 10/100Base TX to
100BaseFX Media Converter, each of them has its own specific
meaning as below table.
LED Color Description
On Power input 1 is active
P1 Green
Off Power input 1 is inactive
On Power input 2 is active
P2 Green
Off Power input 2 is inactive
On Power input 1 or 2 has failed

DIP-Switch
The DIP-Switch is used to configure operation mode for LLF (Link Lose
Forwarding) and operation mode for UTP/Fiber port. The default value
of DIP-switch is OFF.
S/W No Status Description
ON Enables Port/Power Alarm
1 OFF Disable Port/Power Alarm
ON Enables LLF
2 OFF Disables LLF
ON 100Base-FX Half-mode
3 OFF 100Base-FX Full-mode
ON Media mode (100TX to 100FX)
4 OFF Switching mode
Link Lose Forwarding (DIP-Switch 2): When LLF 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, a link fault
pass-through feature is provided in both UTP and Fiber side.
Media mode (DIP-Switch 4): When media 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
8

immediately after the data being received. And TP port should be forced
at 100M in this application. When DIP-Switch is in switching mode
(OFF), the converter function is the same as a Switch Hub.
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.
Ports
RJ-45 ports (Auto MDI/MDIX): The RJ-45 ports are auto-sensing for
10Base-T or 100Base-TX devices connections. Auto MDI/MDIX means
that you can connect to another switch or workstation without changing
straight through or crossover cabling. See figures as below for straight
through and crossover cable schematic.
RJ-45 Pin Assignments
Pin Number Assignment
1 Tx+
2 Tx-
3 Rx+
6 Rx-
Note “+” and “-” signs represent the polarity of the wires that make up
each wire pair.
All ports on this unit support automatic MDI/MDI-X operation, you can
use straight-through cables (See Figure below) for all network
connections to PCs or servers, or to other switches or hubs. In
straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are
connected straight through to pins 1, 2, 3 and 6 at the other end of the
cable. The table below shows the 10BASE-T/ 100BASE-TX MDI and
MDI-X port pin outs.

Fiber Port
The fiber port of SC type connector can work in single mode (30Km).
When you connect the fiber port to another one, please follow the figure
below to connect accordingly. Wrong connection will cause the port
cannot work normally.

ATTENTION This is a Class 1 Laser/LED product. Don’t stare into
the Laser/LED Beam.
Cabling
Twisted-pair segment can be connected with unshielded twisted pair (UTP)
or shielded twisted pair (STP) cable. The cable must comply with the IEEE
802.3u 100Base TX standard for Category 5. The cable between the
converter and the link partner (converter, switch, hub, workstation, etc.)
must be less than 100 meters (328 ft.) long.
Fiber segment using single-mode connector type must use 9/125µm
single-mode fiber cable. User can connect two devices in the distance up
to 30 Kilometers.

and another side of category 5 cables to the network devices’ Ethernet
port (RJ-45 port), ex: switch, PC, or Server. The UTP port (RJ-45) LED on
the unit will light up when the cable connected with the network device.
Please refer to the LED Indicators section for LED light meaning.
7. Connect one end of the fiber cable to the SC single-mode connector on
this converter and the other end of the fiber cable to the SC single-mode
connector on the other 100 Base-FX devices.
