Caution
Circuit devices are sensitive to static electricity, which can damage their delicate
electronics. Dry weather conditions or walking across a carpeted floor may cause you to
acquire a static electrical charge.
To protect your device, always:
• Touch the metal chassis of your computer to ground the static electrical charge before
you pick up the circuit device.
• Pick up the device by holding it on the left and right edges only.
European Community (CE) Electromagnetic Compatibility Directive
This equipment has been tested and found to comply with the protection requirements
of European Emission Standard EN55022/EN61000-3 and the Generic European Immunity
Standard EN55024.

1. Overview
IEEE802.3u 100Mbps Fast Ethernet supports two types of media, 10/100BaseTX and 100Base-FX, for network connection. The media converter has commercial
and industrial different operating temperature optional specification. This media
converter also supports POF (Plastic Optical Fiber) optional networking solution. It
is suitable for in-door and out-door industrial Ethernet with fiber optical cable. The
POF cable can use PROFINET compatible SC-RJ connector, it has special design
for easy fiber cable assembling, the POF cable could be easily assembled on-site
with simple tools. LFP (Link Fault Pass Through) feature enhances the TP-Fiber
Link integrity and conformity.

3. Checklist
Before you start installi ng the Converter, verify that the package contains the
following:
— The TP-Fiber Converter
— AC-DC P ower Adapter or Self Powering Cable(USB) (upon the model user
purchases)
— This User's Manual
Please notify your sales represent ative immediately if any of the aforementioned
items is missing or damaged.
4. Installing the Converter
Wear a grounding device for electrostatic discharge
4.1 TP-Fiber Converter with AC-DC Power Adapter
Note: Please ensure that the power select button is on the left
side of slide switch (See Fig. 6-1).
Verify that the AC-DC adapter conform s to your country AC power requirement
and then insert the power plug
Install the media cable for network connection
4.2 TP-Fiber Converter with Self Powering Cable (USB)
Note: Please ensure that the power select button is on the
right side of slide switch (See Fig. 6-2).
Install USB cable. Plug type A connector in PC's USB port(jack) and type B
connector in the converter's USB port (See Fi g. 2)
Install the media cable for network connection
Warning:
Please make sure that the power of PC/US B Hub is turned
on, or else the converter will not work
TP Port
Default: AUTO
AUTO or FORCE setting, see Fig. 13 S1—Bit 1
Attach TP Cat. 5 cable to TP port, and the distance can
be up to 100m.
Use the straight-through cable to connect t he switch or
workstation, the 10/100 TP port can support AUTO MDI-
"100FDX"/"100HDX" setting, see Fig. 13 S1—Bit 5

5. Link Fault Pass Through
Note: Link fault pass thr ough (LFP) function only takes effect as S1-Bit4 (see Fig.
13) is enabled. Disabled S1-Bit4 will turn this media converter into a general
one.

This media converter supports link fault pass through (LFP) in TX/FX
converter application. Link status on one port is propagated to the other port to
notice the remote nodes. If TP port is unplugged, this converter stops
transmission on fiber port. T his causes the remote fiber node link to fail. LED
shows the link failure on both T P and fiber ports. If fiber link fails, this converter
restarts auto-negotiation on TP port but always stays in the link failure state. This
causes the remote TP node link to fail. LED also shows the link failure on both TP
and fiber ports. Refer to Fig. 9 shown below for the normal status when the link
succeeds. Also refer to Fig. 10 and Fig. 11 for the erroneous status when TP
Cable A , Fiber Cable B or Fiber Cable C fails to connect.
Note : ●

Warning:
The LFP (Link Fault Pass Through) function works only when both two converters own this
capability in pairs. Furthermore, both LFP converters should be supplied only by the same
manufacturer/vender. The connection coming from LFP c onverters with odd models or nonLFP converters will cease the LFP function.

8. Connecting to TP, Fiber Device
AUTO, FORCE selectable: Bit 1, 2, 3 of S1
a. AUTO: 10/100 NWay Auto-negotiation
b. FORCE: 100 or 10, FDX or HDX
100Mbps duplex selectable: Bit 5 of S1
a. FDX for 100FDX fiber link partner, default
b. HDX for 100HDX fiber link partner
S1-1 TP port mode : AUTO (default) or FORCE
S1-2 TP port speed : 100 or 10 when TP at Force
S1-3 TP port duplex : FDX or HDX when TP at Force
S1-4 LFP : LFP enabled (default) or disabled
S1-5 Fiber port duplex : 100FDX (default) or 100HDX
Note:
1. S1-2 and S1-3 will take effect only when S1-1 is set at TP-FORCE.
Warning:
When TP NWay port is connected to TP 100FDX(force mode) instead of NWay
partner, it will result in 100HDX mode with invalid collision signal
Ensure that all network nodes are configured at an identical operation mode.
Improper operation and flow control mode between TP and Fiber port
connections will render the LAN to work poorly

9. Cable Connection Parameter
100Base-X network allows 512-bit time delay between any two node-stations in a
collision domain. Switch-based Media Converter breaks up TP and Fiber segments’
collision domain to extend the cabling distance.
