F/O connection
One optical port conform to 10BASE-FL
(BFOC/2.5 (ST) sockets) enables terminal
equipments or optical network compo-
nents to be connected.
5-pin terminal block
The supply voltage and the indicator
contact are connected via a 5-pin termi-
nal block with screw locking mechanism.

Warning!
The RT1-TP/FL equipment is desi-
gned for operation with SELV.
Only safe extra-low voltages to
IEC950/EN60950/VDE0805 may
therefore be connected to the
supply voltage connections and
to the indicator contact.

– Voltage supply
: The voltage supply
can be connected to be redundant.
Both inputs are decoupled. There is no
load distribution. With redundant sup-
ply, the power pack supplies the RT1-
TP/FL alone with the higher output vol-
tage. The supply voltage is electrically
isolated from the housing.
– Indicator contact:
Contact interrupt
indicates the following by means of a
potential-free indicator contact (relay
contact, closed circuit):
– the failure of at least one of the two
supply voltages.
– a permanent fault in the hub for
ISO/DIN rail (internal 5 V DC voltage,
supply voltage 1 or 2 not in the per-
missible range).
– the faulty link status of the TP port
(port 1), if the setting of DIP switch
LA1 is „ON“.
– the faulty link status of the F/O port
(port 2), if the setting of DIP switch
LA2 is „ON“.
The indication of the link state might
be masked on a port-by-port basis
using the DIP switches LA1 and LA2.
2. Configuration
2.1 CONNECTING TO EXISTING
NETWORKS
Terminal equipments, programable logi-
cal controles (PLC), automates etc. can
be attached by interference insensitive
F/O lines in the industrial ETHERNET
area.
Via the RT1-TP/FL terminal equipments
can be tied to existing ETHERNET net-
works with concentrators of the ASGE-,
MC- and AMC family or Railhubs RH1….
Hints on calculating the maximum net-
work expansion can be found in the
„Ethernet manual“, Chapter 8 (see
„Technical data“ for order number).
The maximum number of cascaded RT1-
TP/FL between terminal equipments or
repeaters is two.

Fig. 4: Possibility of Configuration
The inidicator contact is closed,
– if the power supply is okay.
– if the setting of DIP switch LA1 is
„ON“ and the link status of port 1 is
okay (or if the setting of DIP switch
LA1 is „OFF“).
– if the setting of DIP switch LA2 is
„ON“ and the link status of port 2 is
okay (or if the setting of DIP switch
LA2 is „OFF“).
Note:
In the case of the voltage supply
being routed without redundancy, the
RT1-TP/FL indicates the failure of a supp-
ly voltage. You can prevent this message
by feeding in the supply voltage through
both inputs.
