1. Overview
Thank you for purchasing PLANET FT-80X family 10/100Mbps
Ethernet Twisted pair to 100Base-FX Fiber-optic Bridge
Converter. This converter is used to convert one type media signal
to other type equivalent that allows two type segments connect
easily, efficiently and inexpensively. This converter can be used as
a standalone unit or as a slide-in module to the 19” media chassis
(up to 10 units) for a TP and Fiber combined networks at a central
wiring closet. Please contact with your sales representative for
more about the 19” media chassis.
2. Model List
Your Fast Ethernet Converter comes with one of the following
models.
ðFT-801 : on board ST fiber connector
ðFT-802/S : on board SC fiber connector
Models with last character “S” indicate the fiber-port is with
“Single-Mode” optic fiber connector.
In the following sections, the term “FT-80X” indicates the product
family above.
3. Checklist
Your FT-80X carton should contain the following items:
ðThe Fast Ethernet Bridge Converter
ðAC-DC Power Adapter (Output: 5VDC, 2 A max.)
ðThis user’s guide
If any item is missing or damaged, please consult the dealer from
whom you purchased your Fast Ethernet Converter.

5. Installing the Converter
Please follow these steps to install the converter:

3
•Turn off the power of the device/station in a network to which
the FT-80X will be attached
•Ensure that there is no activity in the network
•Attach fiber cable from the FT-80X to the fiber network. TX,
RX must be paired at both ends
•Attach a Cat. 5 UTP cable from the 10/100Base-TX network
to the RJ-45 port on the FT-80X.
•Connect the 5VDC power adapter to the FT-80X and verify
that the Power LED lights up.
•Turn on the power of the device/station, the TX Link and FX
Link LEDs should light when all cables are attached

6. Duplex Mode setting
The TP port of FT-80X support duplex mode detection by
auto-negotiation (A-N). The following is the duplex mode
parameters:
Fast Ethernet Device FT-80X Duplex
Mode support
Ethernet / Fast Ethernet Hub Half-Duplex
Ethernet / Fast Ethernet Switch (without A-N)
Half-Duplex
Fast Ethernet Devices *
Support Auto-Negotiation Full-Duplex /
Half-Duplex
Note: Normally, an A-N switch will detect and set to
full-duplex, where a dual-speed hub will detects Half.
There is a DIP-switch as in the left view above. Please check
and follow the duplex mode of the fiber device and have the
duplex selection to your FT-80X.
