Handling
• The POF network converter and the wall plug transformer are solely intended to
be used in dry indoor locations; the product must not get damp or wet. Wall plug
transformers have the potential to cause a fatal electric shock!
• Never use the product soon after taking it from a cold room to a warm one. The
condensation that forms might damage the product under certain circumstances.
The wall plug transformer also poses a risk for a potentially fatal electric shock!
Allow the product to reach room temperature before connecting it to the power
supply and putting it to use. This may take several hours.
• Any maintenance or repair work may only be performed by an authorised repair
shop.
• Check the product for damage before use!
If you detect any damage, DO NOT connect the product to the mains supply!
Safe operation can no longer be assumed if:
- the product shows visible signs of damage
- the product does not function or does not function properly (e.g. a burning smell)
- the product was stored under unfavourable conditions
- it was exposed to heavy loads during transport
• When connecting and operating the device, make sure the cables are not bent or
jammed.
• Avoid the following adverse conditions at the installation location and during trans-
port:
- Excessive humidity or dampness
- Extreme cold or heat
- Dust or
fl
ammable gases, fumes or solvents
- Strong vibrations
• If the product is not to be used for some time (e.g. during storage), unplug the wall
plug transformer.
Maintenance and Cleaning
Maintenance or repair may be performed only by quali
fi
ed personnel or a specialised repair
shop. The product contains no parts that require servicing. Therefore, do not open/dismantle it.
Use a clean, dry, soft cloth for cleaning.
Dust can easily be removed using a clean long-haired brush and a vacuum cleaner.
Do not use abrasive cleaning agents, cleaning alcohol or other chemical solutions,
since these could damage the surfaces or even impair operation.

Troubleshooting
No network connection
• Check the LEDs on the RJ45 socket. With an active network connection, one LED should
light up continuously (LINK status), the other LED must
fl
ash during data transfer.
• Check the power supply to the POF / network converter.
The USB port to which the POF / network converter is connected must be able to supply a
current of 500 mA.
Use the included wall plug transformer for power supply on a trial basis.
• Is there a bend in the POF cable? This prevents light transmission, and hence the network
connection.
Perhaps the POF cable can be “straightened”. Depending on the intensity of the bend, the
cable must be shortened accordingly to remove the bend.
• Check whether the two leads of the POF cable you are using are properly seated in the snap
lock.
• Due to the optical properties of POF
fi
bres, large cable lengths as in “real”
fi
bre-optic cables
are not possible. For optimum cutting edge, up to 50 m is possible.
• Make sure that the two leads of the POF cable are connected in a crossed manner.
This means that the “R” port on one POF / network converter must be connected with the port
“T” on a second converter (or a switch with POF connection, etc.) and vice versa.
Slow or unstable data transfer
• Many bends (especially small radii) shorten the possible cable length and/or reduce the
speed of data transmission.
• Check whether the leads of the POF cable are properly seated in the snap locks. An air gap
between the cutting edges of the optical
fi
bres, and the transceiver unit in the POF / network
converters leads to frequent errors, so that data packets need to be retransmitted.
If necessary, cut once again both ends of the used POF cable properly. To do this, use a
suitable POF cutter.
• Due to the optical properties of POF
fi
bres, large cable lengths as in “real”
fi
bre-optic cables
are not possible. For optimum cutting edge, up to 50 m is possible.
• In the network card settings (for example, in the Windows Device Manager, open the proper-
ties window of the network interface, and possibly open the advanced properties), the so-
called
fl
ow control must be enabled. Then restart Windows.
Check light transmission
• Put the POF / network converter in operation (e.g. via the wall plug transformer included in
the delivery). Follow the same approach as with the existing POF / network converter or a
switch with POF connection.
Release the snap lock of the POF / network converter and pull out both leads of the POF
cable.
One of the leads should light up red. This lead must be connected to the “R” port of the POF /
network converter. The second lead that is not lit up must be connected to the “T” port.
It is important that the ports “R” and “T” on the two devices must be connected at each end
of the POF cable in a crossed manner.
Disposal
