General features  
The MICROSENS Fast Ethernet mini bridge permits the connection of  
two Fast Ethernet segments according to IEEE802.3u.  
The bridge offers the conversion 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 distances 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.

deactivate (FORCE) the autonegotiation protocol on the copper port.  
When the autonegotiation is deactivated switches 2 and 3 port select the  
speed 10 or 100 Mbit/s and full or half duplex.  
Fig. 4 Configuration switches  
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).

Warning:  
When TP NWay port is connected 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 operation and flow control mode between TP  
and fiber port connections will render the LAN to work poorly.
