100 MBit/s fiber optic ports (100BASE-FX,
Duplex SC connector).
It is possible to connect up to three DTEs or
other TP/TX network segments to the TP/TX
ports using twisted pair cabling. Two further
DTEs or optical network components can be
connected to the fiber ports.

The RS2-4TX/1FX… modules have four
10/100 MBit/s twisted pair ports
(10/100BASE-TX, RJ45 connectors) and one
100 MBit/s fiber optic port (100BASE-FX,
Duplex SC connector or ST connector on
R2-4TX/1FX-ST EEC).
The RS2-4TX EEC module has four
10/100 MBit/s twisted pair ports
(10/100BASE-TX, RJ45 connectors).
It is possible to connect up to four DTEs or
other TP/TX network segments to the TP/TX
ports using twisted pair cabling. One further
DTE or optical network component can be

1. Functional description

The 10/100BASE-T(X) ports of a RS2­xTX/xFX EEC represent a terminal connec­tion for the connected LAN segment. You
can connect single devices or complete net­work segments.

1.1 FRAME SWITCHING FUNCTIONS
Store and Forward

All data received by the RS2-xTX/xFX EEC
from the system bus or at the ports is
stored and checked for validity. Frames
> 1536 bytes as well as fragments (< 64
bytes) are discarded. The RS2-xTX/xFX EEC
forwards the valid frames.

Multi address capability

A RS2-xTX/xFX EEC learns all source
addresses per port. Only packets with
– unknown addresses
– addresses learnt at this port
– a multi/broadcast address
in the destination address field are sent to
this port.
A RS2-xTX/xFX EEC learns up to 1,000
addresses. This becomes necessary if more
than one terminal device is connected to
one or more ports. In this way several inde­pendent subnetworks can be connected to a
RS2-xTX/xFX EEC.

Learnt addresses

A RS2-xTX/xFX EEC monitors the age of the
learned addresses. The RS2-xTX/xFX EEC
deletes address entries from the address
table which exceed a certain age (300
seconds).
Note: Restarting deletes the learned
address entries.

Tagging (IEEE 802.1Q)
The IEEE 802.1 Q standard designates the
VLAN tag to be included in a MAC data
frame for the VLAN and prioritizing func­tions. The VLAN tag consists of 4 bytes (2
bytes tag protocol identifier TPID, 2 bytes
tag control information TCI). It is inserted
between the source address field and the
type field. Data packets with a VLAN tag are
transmitted unchanged by the RS2-xTX/xFX
EEC.

1.2 SPECIFIC FUNCTIONS OF THE
TP/TX INTERFACE
Link control

The RS2-xTX/xFX EEC monitors the connec­ted TP/TX line segments for short-circuits or
interrupts using regular Idle signals in
accordance with IEEE standard 802.3
10/100BASE-T/TX. The RS2-xTX/xFX EEC
does not transmit any data to a TP/TX seg­ment from which it does not receive an Idle
signal.

Note: A non-occupied interface is assessed
as a line interrupt. The TP/TX line to termi­nal equipment which is switched off is like­wise assessed as a line interrupt as the de­energised bus coupler cannot transmit Idle
signals.

Auto polarity exchange

If the receive line pair is incorrectly connec­ted (RD+ and RD- switched) polarity is auto­matically reversed.

Autocrossing

The RS2-xTX/xFX EEC detects the transmit
and receive pairs (MDI, MDI-X). The
RS2-xTX/xFX EEC automatically con­figures its port for the correct transmit and
receive pins. Consequently it does not
matter whether you connect devices using
a cross-over or straight cable.

1.3 SPECIFIC FUNCTIONS OF THE
F/O INTERFACE
Link control

The RS2-xTX/xFX EEC monitors the connec­ted F/O line for interrupts using idle signals
during frame pauses in accordance with
IEEE standard 802.3 100BASE-FX. The
RS2-xTX/xFX EEC transmits no data to a F/O
line from which it is receiving no idle signal.

Low Light Detection

If the optical input power decreases below
the low light threshold the transmit and
receive path will be disabled for data and
the idle signal will be transmitted.

Far-End Fault

The optical transmission distance of the
RS2-xTX/xFX EEC can be monitored in
receiving direction as well as in transmitting
direction, if the other side also supports Far­End Fault. If the other side does not support
Far-End Fault, the optical transmission
distance is monitored only in receiving
direction.
Far-End Fault is sent, if the optical input
power at the optical port has fallen under
the low light level. If Far-End Fault is re­ceived, the link stays inactive (DA/STAT LED
dark).

1.4 FURTHER FUNCTIONS
AND FEATURES
Reset

The RS2-xTX/xFX EEC will be reset by the
following action:
– input voltages fall below a threshold

After a reset the following action is carried
out:
– initialization

by means of a potential-free indicator
contact (relay contact, closed circuit):
– the failure of at least one of the two

supply voltages (supply voltage 1 or 2
< 9.6 V).

– a permanent fault in the RS2-xTX/xFX

EEC (internal voltage supply).

– the faulty link status of at least one port.

The indication of the link state on the
RS2-xTX/xFX EEC can be masked on a
port-by-port basis using the DIP swit­ches LA1 to LA5 (LA1 to LA4 on
RS2-4TX EEC).
State of delivery: link test is activated.

Ground connection

The RS2-xTX/xFX EEC is grounded via a
separate screw connection.

Fig. 4: Configuration with RS2-xTX/xFX EEC: Connection of up to 4 data terminal equipments (4 on RS2-4TX/1FX…, 3 on RS2-3TX/2FX…)
or further segments via TP/TX as well as connection via fiber optic cable with up to 2 optical ports (1 on RS2-4TX/1FX…, 2 on RS2­3TX/2FX….

1.7 CONTROLS
5-pole DIP switch
(Suppressing the link states)

With a DIP switch on the front panel of the
RS2-xTX/xFX EEC the indication of the link
states by the indicator contact can be sup­pressed port by port. Using the switches
LA1 to LA5 (LA1 to LA4 on RS2-4TX EEC),
the indication of the link states can be sup­pressed.
Switch position „ON“: the indication of the
link state is not suppressed, that is the indi­cator contact indicates the unvalid link.
State of delivery: LA1 to LA5 (LA1 to LA4 on
RS2-4TX EEC) in position „ON“ (position 1).
