Installation
This section will guide you through the installation of your media converter. Please read
through the instructions carefully and complete each step in the order listed.
WARNING! Exposure to live fiber optic cable can potentially pose an irreversable threat
to your vision. Under no circumstances should you look directly into a fiber optic
cable. Before you begin make sure that all devices are turned off and disconnected and
keep fiber optic cables pointed away from your eyes and face at all times. The delicate
nature of fiber optic cabling also means it can be easily damaged or broken. Be sure to
handle fiber optic cables carefully.
1. Plug your Category 5 or above UTP straight-through cable into the RJ-45 LAN port.
2. If the other end of the cable is connected to a PC or adapter, make sure that the
To PC/To Hub button is in the To P C position. If the other end of the cable is attached
to a hub or switch, make sure the To PC/To Hub button is in the To Hub position.

3. Remove the rubber dust caps from the 100BaseFX ports. Plug your ST or SC fiber
optic transmission cable into the TX port. Plug your receiving cable into the RX port.
NOTE: Always re-install the dust caps when the unit is not in use.
4. Set the Full-Half Fiber switch to either Full (full-duplex, 200 Mbps) or Half (halfduplex, 100 Mbps) depending on your preference.
NOTE: The ET9110SC and ET9110ST use an “Auto-Reset” function. While you are using
the converter, you can flip between fiber full- and half-duplex modes without having to
manually power down or reset the converter.
5. Plug one end of the power supply into the 9V DC port on the converter. Plug the
other end into an available electric socket.

Blinking Receiving data on Ethernet
Using the Loop-Back Testing Feature
These media converters feature a fiber loop-back testing function that allows you to
confirm that the fiber or Ethernet circuit loop is complete. The local unit will send out a
detect message that includes both command and test-pattern data to the remote unit and
request an answer. When the remote unit receives the message, it will attempt to
recognize the command and deliver the test-pattern data back to the local unit to
complete the circuit loop.
You can engage the loop-back testing feature by setting the Loop Back Testing switch to
the LBT On position. To exit Loop-Back Testing mode, set the switch to the Normal
position. While you are in Loop-Back Testing mode, other fiber transmissions will be
halted. If the local unit can not access the remote unit, the circuit loop is broken and the
Power LED will flash rapidly.
NOTE: If the local unit is in Loop-Back Testing mode, make sure that the remote unit is
operating in Normal mode.
The Link-Loss-Forwarding Application
The media converter uses a Fiber Link Forwarding feature that allows indirect sensing of
a Fiber Link Loss via the 100 Base-TX UTP connection. When the media converter detects
a Link Loss condition on the Receive fiber (Fiber LNK OFF), it disables the UTP
transmitter so that a Link Loss condition will be sensed on the receive UTP port. The
Link Loss can then be sensed and reported by a Network Management agent at the
remote UTP port’s host equipment.
This feature has no effect on the media converter’s UTP LNK LED, which continues to
function normally, independent of the state of the Fiber LNK LED and the UTP
transmitter.
