Operating Instructions

2.1

Scope of Application

The RS232 / FO Converter is used for converting RS232 signals to
signals for FO conductors with BOFC ST-connectors. It is equipped with
one FO channel and one RS232 channel and switches automatically
from "FO receiving data" to "FO transmitting data".
A power supply is integrated in the housing to generate the voltage
required for the converter board from the auxiliary power supply.
The RS232 / FO converter can be used for transmission rates up to
115200 bauds.
2.2

General Data

The signal converter has a plastic housing that can be snapped onto a
DIN EN 50022 mounting rail.
The auxiliary power supply is fed in via two terminals. Because of ist
extremely wide auxiliary voltage range (DC 24-250V and AC 60-250V),
the converter can be connected without switchover to all common types
of station batteries and AC mains voltage supplies.
The front cover has a green LED for indication of the operating voltage
status. The status of the internal +5V operating voltage can be checked
by means of a potential-free relay contact that is brought out to two
terminals. An open contact means that the operating voltage is o.k. The
readiness for service of the unit is indicated by means of a potential-free
signalling contact (terminals 1,2) that can be used to communicate the
following fault conditions to a control center:
• No supply voltage
• Failure of internal power supply
When a fault condition is present, the contact is closed.
