General features

The MICROSENS Fast Ethernet mini bridge permits the connection of
two Fast Ethernet segments according to IEEE802.3u.
The bridge offers the c onversion from full to half duplex, as well as the
coupling of Ethernet to Fast Ethernet segments.
Thanks to the conversion into full duplex the limit of 412 m for a Fast
Ethernet segment does no longer exist. With single mode fiber, it is
possible to cover dist ances up to 125 km.
The10/100Base-TX port with autonegotiation permits the connection of
10Base-T and 100Base-TX devices and the self-learning filter function
reduces the data traffic between the coupled segments.
Multiple LEDs show the status of the bridge and can be used for network
diagnostics.

Getting started

2.

Before you start instal l i ng t he converter, check that t he package contains
the following items:

• The TP-Fiber bridge

• AC power supply or optional self powering cable (USB )

• This Installation manual

Power connection

3.
TP-Fiber bridge with AC power supply

Please ensure that the sel ection s witch for the power supply i s on the left
side (facing to the 5 V DC input, see. fig. 2).
Verify that the AC power supply conforms to your country AC power
requirement and then insert the power connector. Afterwards c onnect t he
network cables.

TP-Fiber converter with self powering cable (USB, optional )

Please ensure that the switc h for the power supply is on the right side
(facing to the USB port, see fig.2).
Install the USB cable firs t, connector t ype A must be connected to the PC
and connector type B to the bridge. Afterwards connect the network
cables.
Warning: Pleas e make sure that the power of PC/USB hub is turned on,
otherwise the bridge will not work.

4.

Configuration

Please configure t he bridge with the DIP switches loc ated at the side of
the chassis (see fi g. 4).
The following features can be configured:
Autonegotiation: With the switch 1 you can activate (AUTO) or
deactivate (FORCE) the autonegotiation protocol on the copper port.
When the autonegotiat ion is deacti vated switches 2 and 3 port select the
speed 10 or 100 Mbit/s and full or half duplex.
Link Through: Link Through can be selected with switch 4. Position LT
means that Link Through is activated at position LT DIS means this
feature is disabled (refer to chapter Link Through).
Duplex mode fiber port: Switch 5 selec ts the duplex mode of the fiber
(100Base-FX) port. Position FDX is for full duplex and HDX for half
duplex transmission.

Warning:

• When TP NW ay port is c onnected to TP 100FDX (force mode)
instead of NWay partner, it will result in 100HDX mode with
invalid collision signal.

• Ensure that all network nodes are configured in an identical
mode. Improper operat ion and flow control mode between TP
and fiber port connections will render the LAN to work poorly.

Link Through

5.

Note: Link Through function only takes effect when switch 4 is set to
activated.
This bridge supports Link Through (LT) function in TX/FX converter
application. The li nk st atus on one port is propagat ed to the other port to
notice the remote nodes. If TP port is unplugged, this converter stops
transmission on f iber port. This causes t he remote fiber node link t o fail.
The LEDs show a failure on both, TP and f iber ports . I f f iber link fai ls, thi s
converter restarts autonegoti ation on TP port but always st ays in the link
failure state. This c auses the remote TP node link to fail. The LE Ds also
show the link failure on both, TP and fi ber port (see fig. 5 and fig. 6).

Warning: The Link Through function works onl y when thes e bri dges are
used in a pair and both have the link through ac tivated. Furthermore both
link through bridges should be suppl i ed by the same manufacturer.
Connections coming f rom old link through bridges or bridges without link
through will cease the link through function.

LED displays

6.

The bridge has 5 integrated LEDs giving s tatus inform ation which can be
used for error diagnostics. Please refer to f ig. 8 for a descript ion of these
LEDs.

Power supply

7.

The bridge is supplied with an external AC power supply. The bridge
requires 5 V DC input. Becaus e of warranty reasons it is only allowed to
use the original power supply.
The DC jack’s central post is 2.5 mm wide (see fig.7).
Optional the bridge can be powered by an USB port. When selected the
USB power mode a special USB c able is included at delivery. With this
cable the bridge can be connected t o a PC with USB port or a USB hub.

8. Safety notes

DANGER! - Optical components may radiate laser light.

WARNING: Infrared radiation as used for data transmission within the
fiber optic area which, although invisible to the human eye, can
nevertheless cause dam age.

To avoid damage to the eyes:

• Never look straight into the out put of fiber optic components –
danger of blinding!

• Cover all unused optical connections with caps.

• Commission the transmission link only after completing all

connections.

The active laser components used with this product comply with the
provisions of Laser Class 1.

DANGER! – Conductive parts from Power- and Telecommunication
networks can transport dangerous voltage.

To avoid electrical shocks, all installations must be confirm to the
required safety standards if the region where they are used.
