Wiesemann & Theis offers an entire family of compact self-powered
ber optic interfaces that allows you to convert RS232 serial ports
into an optical port for connecting POF cable.
This interface family is described on the following pages along
with the corresponding technical data and including connection
examples.
For up-to-date information on new developments, see our Internet
site at http://www.wut.de or check the e-mail short notices at the
W&T Interface Club, which you can also subscribe to from the W&T

Warning note concept
This manual contains notes which must be observed for your
personal safety and to prevent equipment damage. The notes are
called out with a warning triangle. Depending on the hazard level
the warning notes are represented in decreasing order of hazard as
follows:
1DANGER
Indicates a hazard which will result in death or serious injury if no
appropriate safety measures are taken.
1WARNING
Indicates a hazard which can result in death or serious injury if no
appropriate safety measures are taken.
1CAUTION
Indicates a hazard which can result in slight injury if no appropriate
safety measures are taken.
1NOTE
Indicates a hazard which can result in equipment damage if no
appropriate safety measures are taken.
When multiple hazard levels are present the warning note for the
highest level is used. If the warning triangle for personal injury is
used, then a warning for equipment damage may also be added in
the same warning note.

Safety instructions
General precautions
This manual is intended for the installer of the described devices
and must be read and understood before beginning any work. The
devices are to be installed and placed in service only by an electrical
specialist.
Intended use
1DANGER
The ber optic interfaces from Wiesemann & Theis convert the data
signals from RS232 interfaces into light signals, thereby enabling
the transmission of serial data over plastic ber optic cables. This
allows the interfaces to suppress compensation currents which
can ow as a result of potential differences between the connected
devices when directly copper connections are used. Such currents
can cause interference with data transmission or even destroy the
interfaces.
The interfaces described in this manual are primarily designed
for protecting RS232 ports and for ensuring noise-free data
transmission in noisy environments.When using the interfaces
for personal protection against contact with hazardous voltages,
observe the relevant safety standards and regulations.
Any other use or modication of the interface convertors is not
permitted.

Electrical safety
1WARNING
If an additional power supply is used, it must provide safe isolation
of the low-voltage side from the supply network in accordance with
EN60950-1 / EN62368-1. In addition, the power supply must have an
LPS feature.
Optical radiation
1NOTE
All W&T ber optic interfaces for plastic ber optic cables use a
standard LED with a wavelength of 660nm as the optical emitter.
Because of the limited energy which the serial port has available, the
LEDs only couple an optical power of typ. -7dBm (approx. 0.2mW)
into the bers.
This precludes any health risk from the optical radiation.
EMC
1NOTE
Only shielded serial signal cables should be used to connect ber
optic interfaces. Alternately the interfaces can of course be plugged
directly into the respective RS232 port.
The ber optic interfaces then meet the industrial noise limits and
the stricter emissions limits for residential and small businesses.

Notes for use of the ber optic interfaces
All specifications for maximum transmission parameters refer
to operation of the interfaces on serial ports equipped with type
MC1488 RS232 drivers and at a voltage of ±12V. The specications
also presume that the handshake lines of the interface are enabled.
If the interfaces are supplied only from the data lines, and when
operating on low-eciency RS232 ports you must take into account
limitations with respect to maximum transmission length, baud rate
and temperature range.
Since maintaining of all three parameters is a direct function of the
construction of the RS232 port and a solid power supply for the
ports, and these parameters have a mutual effect, it is not possible
to suggest specic values.
Practice has shown that for RS232 ports equipped with MAX232-
compatible IC’s, no operating restrictions exist as long as the
handshake lines on the port are enabled.
Laptop ports with low output levels are however only in exceptional
cases able to provide the ber optic interfaces with sucient power.
For short distances, however (up to max. 20 meters), there is a
special power-saving version 81029, which can be purchased for
such applications.
When there are power supply problems, it is always however
possible to supply the interface converter externally through its
handshake inputs with a voltage of up to 9V, or to use ber optic
interfaces with their own power supply (such as our model 81201).
The specied minimum distance of 5 meters for the 81009 Interface
only applies if the Interface is operated on an RS232 port with high
output levels. If under these conditions a short cable length is
required, a model 81029 may also be used.

Ambient conditions for the use of POF cables
If the POF cable is permanently exposed to a high relative humidity,
the cable attenuation will increase signicantly. Although this effect
is reversible with decreasing humidity values, it can lead to trans-
mission failures if a combination of large cable length, fast baud
rate and limited performance of the serial interface is used.
For reliable optical data transmission even in humid environments,
the length of the POF cable should not exceed 50 meters for the
81009 model and 70 meters for the 81025/81026 models.
For larger lengths, glass bre should be used to ensure long-term
reliable operation under the mentioned operating conditions.
