Serial/bre-optic converter
If high interference immunity is needed or long transmission
distances are involved, then bre-optic transmission is
advisable. Another benet of using bre-optic transmission
is that it is not sensitive to electromagnetic inuences.
One simple and inexpensive solution is media
converters, which can convert serial signals from from a
RS232/422/485 port on a bre optic port with an SC or
ST glass bre connection. Fibre-optics with multimode
technology make it possible to transmit over distances of up
to 5000 m without additional power boosters.
Ring operation
The converter is able to connect several serial devices to
form a glass bre ring. This simply involves connecting the
TX port of one converter with the Rx port of a neighbouring
converter. Ring mode can then be activated using the DIP
switch on the device. A signal which is transmitted by a
node is then forwarded in the ring until it is gets back to the
sender, where it is blocked. In this way, glass bre rings can
be congured with an spread of up to 100 km.
Automatic baud rate detection
The serial/bre-optic converter can automatically detect
the serial baud rate of connected devices. This ensures that
signals can be forwarded by the media converter without
any data loss even if the baud rate of a connected device
changes.
