2 1 Operating Instructions
2.1 1.1 Scope of Application
The Mini Star Coupler is used for optical connection of up to four
terminal units with an optical interface in a star topology to a master unit
for centralized operation, thus allowing to establish an inter-ference-
immune connection between the field devices and the centralized
operating unit. Direct communication between a PC and the terminal
units is possible via the integrated RS232 interface.
2.2 Technical Features
The optical mini star coupler distributes the messages to all terminal
units via up to 4 optical interfaces. The number of terminal units can be
increased by a cascade connection. The transmitter output of the mini
star coupler is connected to the receiver input of the appropriate terminal
unit. As the messages contain an address, only the addressed terminal
unit responds. The terminal unit then answers to the PC via the mini star
coupler's receiving and transmitting interface. It is thus possible to
optically connect up to four terminal units to a central unit. Cascading of
the mini star coupler is possible.
•All optical inputs and outputs (full duplex) have ST-BOFC
connectors and can be set individually to Light ON or Light OFF in
idle state.
•Data transmission is transparent, i.e. protocol-independent.
•The wavelength of all optical inputs and outputs is 820 nm.
•The typical distance to the system interfaces of the protection
devices spanned by FO cables is 1.5 km.
•The star coupler has an integrated power supply unit and is
lodgedin a plastic housing.
•The auxiliary power supply of the star coupler can be operated
without switchover in the rated voltage ranges of DC 24 - 250V and
AC 60 - 230V.
•LEDs are provided for indication of the operating voltage (green
LED) and of data transmission (yellow LEDs).
2.3 General Data
The star coupler is equipped with one optical PC input and output and
4 optical inputs and outputs to the terminal units. Cascading of the star
Page 8 of 28 Mini-Starcoupler 19.10.2006

coupler is possible. The Mini-Starcoupler has a plastic housing that can
be snapped onto a DIN EN 50022 rail. The auxiliary power supply is fed
in via terminals on one side of the housing. Because of its extremely
wide auxiliary voltage range (DC 24 - 250 V and AC 60 - 250 V), the
Starcoupler can be connected without switchover to all common types of
station batteries and AC mains voltage supplies.
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.
2.4 Data Transfer
Operation of the mini star coupler is transparent and full-duplex. Data
received from the master unit are forwarded by the receiver of channel
1 to all outputs (channels 2, 3, 4 and 5). Data from one of the outputs
(channel 2, 3, 4 and 5) are sent to the transmitter of channel 1. The logic
of the optical interfaces is positive (Light OFF in idle state), incoming
light signals are treated as active = 1 (high). For use in systems
operating
with a negative logic, the star coupler can be switched over to negative
logic by means of a switch that is accessible from outside. Inversion of
the logic applies to both the optical input and the optical output of this
interface. On delivery, the star coupler is set to positive logic (Light OFF
in idle state). When set to negative logic, the receiver must have light in
idle state, otherwise the star coupler is blocked.

2.5 Connection to a PC with Serial Interface
For central remote, the serial interface of the star coupler can be
connected to a PC by means of a serial cable. Pins 7 and 8 of this cable
must be jumpered. (Note that this deactivates FO Input channel 1).
The serial interface distributes data to the four FO channels and receives
data from these channels.

2.6 FO-Connections
The receiving optical connectors are marked with Rx, the transmitting
connections with Tx.
ATTENTION! Please tight the mechanical screw connections of the FO -
cables with FSMA plug carefully and only by hand (do not use tools).
The ST plugs are to be shifted with the lateral nose into the groove of the
device connection and locked afterwards. During the installation of the
FO - cables the bending radius specified for the cable is to be kept.
