Introduction
Thank you for choosing the PALM SIZE 10BASE-T Ethernet
Hub. The hub was designed and manufactured to give you
years of trouble-free and reliable service.
The hub is designed for plug-and-play installation and easy
management. The hub provides an Uplink connection (shared
with Port 1) for your network expansion via a RJ-45 MDI-II
connector, making it easy to link two or more hubs together.
The hub features LINK/RX LEDs to show the network
connection and packet receiving status of each twisted pair port.
PWR (power) and COL (collision) indicators show the
operational status of the hub.
Product Features
?? Compliance with IEEE 802.3 10Base -T and 10Base-2
(TE-910plus only) standard.
?? Automatic partitioning function of each port to isolate
network failure.
?? RJ45 ports support Category 3 or better twisted-pair
cable.
?? LED indicators for each twisted pair port for link and
receive status.
?? Uplink jack for easy linking of two hubs to further expand
the network.
?? Compact in size.

Rear Panel Connectors
RJ45 MDI -X Twisted-pair Jacks
Use these jacks to connect Ethernet devices
(server/workstation/print server) to the hub. These are MDI-X
(Medium Dependent Interface, Cross-Wired) jacks, which
means you can use ordinary stright-through twisted-pair cables
to connect workstations and servers to the hub. If you need to
connect another device with an MDI-X jack, such as another
4
hub or an Ethernet switch, you should use a crossver cable, or
make the connection using the Uplink jack.
Uplink Jack
The Uplink jack is an MDI-II jack, which means you can
connect the hub to an Ethernet device’s (i.e. Hub or Switch)
MDI-X port using straight-through cable.
Port1 and the Uplink port is really the same port, except their
pinouts are different. Do not use both Port -1 (1X) and the
Uplink port at the same time.
When uplinking hubs together, please do not exceed the
“4-repeater (hub) count, 3 segments, and 2 populated
segments” Ethernet connection rule. Basically, you can only
uplink 4 hubs together using the UTP cable. The maximum
CAT3, 4, or 5 twisted pair cable di stance between two Ethernet
devices is 100 meters. If you have question about this rule,
please contact our support department at
techsupport@trendware.com.
BNC Port (TE910plus only)
To connect the 10Base -2 network, attach the thin coax cable’s
BNC “T Connector” to the BNC port. Terminate the open end
of the “T Connector” with a 50 Ohms Terminator. The coax
cable should be marked RG58U or RG58 A/U, the maximum
cable length between the two terminators is 185 meters, and
you can connect up to 30 nodes on this cable.
Power Jack
For connecting the External power adapter.

Installation
Installing the Hub
The site where you install the hub may greatly affect
its performance. When installing, consider the
following pointers:
Install the hub in a fairly cool and dry place, for
the acceptable temperature and humidity operating
ranges.
?? Install the hub in a site free from strong
electromagnetic field generators (i.e.
motors), vibration, dust, and direct
exposure to sunlight.
?? Leave at least 10 cm of space at the front
and rear of the hub for ventilation. Note not
to block the ventilation holes on the top of
the hub.
?? Install the hub on a sturdy, level surface
that can support its weight.
?? You can stack two or more hubs together by
inserting the two small round legs at the
bottom of the hub to the two holes on top of
another hub.
Connecting the Power Adapter
Power is supplied to the Ethernet Hub through an AC
power adapter. Connect the adapter to the power
outlet and then connect the plug to the hub’s power
jack.

Cables and Connectors
Twisted-Pair Cable: Category 3 or better
unshielded twisted-pair or EIA/TIA-568 compliant,
100-ohm shielded twisted-pair data cable with 0.4
to 0.6 mm (22 to 26 AWG) wires in two or four
twisted pairs (only two pairs, four wires, are used
for 10BASE-T).
Maximum segment length: 100 meters.
Connectors: RJ-45.

Twisted-pair Crossover Cables
When making an uplink connection between two hubs (or
between a hub and a switch, a bridge, or other Ethernet device)
using MDI-X type jacks at both ends, you must use a crossover
cable. In a crossover cable, two pairs of wires are switched at
one end. Carry out the following steps to create a crossover
twisted-pair cable:
1. Leave one end of the cable as -is, with the wiring on the
RJ-45 connector unchanged. The wiring needs to be
modified at one end only.
2. At the other end of the cable, connect wire 1 from the
unchanged connector to wire position 2, connect wire 3
to wire position 6, connect wires 3 to wire position 1
and connect wire 1 to wire position 2. Refer to the
following diagram:
