LMR8TT
Ethernet Mini
Hub/Repeater
Installation Guide
The Lantronix LMR8TT is a 10BASE-T Mini hub
that provides wiring connections for up to eight
unshielded twisted pair (UTP) ports. An uplink
port is provided for cascading two hubs.
The LMR8TT constantly monitors each port for
signal quality and will automatically disconnect a
device producing noise or excessive collisions.
The device will automatically be reconnected
when the error condition has cleared.
Data packets that exceed the maximum legal
length for IEEE 802.3 Ethernet packets are
automatically truncated. This prevents a device
from blocking the network by transmitting a
continuous data stream or extra long packet.
The LMR8TT retimes and restores full amplitude
wave forms for each retransmitted packet. A full
length preamble is also generated ensuring
packet integrity across the network.
Compact, light and robust, the LMR8TT
provides the ideal solution for small and medium
10BASE-T LAN environments.

Features
▼ The LMR8TT is a cost-effective
unmanaged repeater that allows the
interconnection of 10BASE-T segments.
▼ The LMR8TT provides an additional UTP
uplink port to enable LMR8TT hubs to be
cascaded together using a standard
'straight' cable.
▼ The LMR8TT accommodates cascaded
bus or daisy-chain topologies. Up to 98
ports can be easily daisy-chained per
Ethernet segment
▼ The LMR8TT includes preamble
regeneration, signal retiming and
restoration, extension of fragmented
packets and jabber function for automatic
partitioning.
▼ Power, collision, activity LEDs and
individual port link LEDs aid network
diagnosis and management
▼ The LMR8TT complies with IEEE 802.3
10BASE-T twisted pair standards.
▼ The LMR8TT comes with a 5 year
warranty.
