Introduction
Intended Audience: This manual assumes that the user has a general working
knowledge of networking principles and architecture and is familiar with
network systems in general.
Congratulations on the purchase of your Kingston EtheRx WorkGroup (WG)
series and Stackable-Enhanced (SE) series 10BASE-T Ethernet hubs. There are
two models for each series: KNE8TP/WG and KNE16TP/WG, 8 and 16-Port
WorkGroup hubs, and KNE8TP/SE and KNE16TP/SE, 8 and 16-Port
Stackable hubs. The SE hubs have the same list of features as the WorkGroup
hubs, but also include stacking ports located on the front panel to stack up to
five (5) SE hubs in the same network segment. The EtheRx WG and SE hubs
are multi-port repeaters that conform to IEEE 802.3 10Mbit/sec CSMA/CD
(Carrier Sense Multiple Access with Collision Detection) Network.
The EtheRx WG and SE hubs support eight (8) or sixteen (16) UTP
(Unshielded Twisted-Pair) ports for 10BASE-T network connections, and one
BNC port for 10BASE2 thin Ethernet connection. The 16-Port models also
include one AUI (Attachment Unit Interface) port for either 10BASE2
Cheapernet, 10BASE5 thick Ethernet connection, 10BASE-T or FOIRL (Fiber
Optic Inter Repeater Link) segment using a proper external transceiver. All
models include: a cascade switch on the last UTP port (Port 8 or Port 16)
which supports both straight-through or crossover cable types by simply
moving the switch on the front panel. The UTP ports use 2-color LEDs to show
three states of operation: link, activity and partition. The AUI and BNC ports
use 2-color LEDs to show two states of operation: activity and partition. The
EtheRx hubs also include utilization and collision LEDs to visually monitor the
level of network traffic and number of collisions in five LED percentage levels.
For the remainder of this manual, these hubs will be referred to collectively as
the EtheRx hubs. When necessary for clarification, the four models will be
differentiated as follows:
• KNE8TP/WG
• KNE16TP/WG
• KNE8TP/SE
• KNE16TP/SE

Design Features
Design Features
The EtheRx hub complies with the full set of repeater basic functions as
defined by IEEE 802.3, Section 9. These functions include all Repeater
Functions, Signal Regeneration, Jabber Lockup Protection, Fragment
Extension, Collision Handling, Auto Partitioning/Reconnection, and Link Test.
These functions are usually transparent to all network activities and are
summarized below.
Repeater Functions
If any single port senses the start of a valid packet on its receiving line, the
EtheRx hub will re-transmit the received data to all other ports on the network.
The re-transmission of packets complies with the IEEE 802.3 specification in
terms of preamble structure, voltage amplitude, and timing characteristics.
These timing regenerations prevent cumulative signal loss, jitter, and distortion
caused by the network cabling, and allow the EtheRx hubs to be cascaded to
other Ethernet hubs.
Jabber Lock-up Protection
The EtheRx hub implements a built-in MAU jabber lockup protection (MJLP)
scheme to ensure that the network is not disabled due to transmission of
excessively long data packets. This protection scheme will automatically
interrupt excessively long transmissions to prevent jabber lock-up.
Fragment Extension
If the total packet length received by the EtheRx hub is less than 96 bits,
including preamble, then the hub will automatically extend the repeated packet
length to 96 bits by appending a jam sequence to the original fragment. The
extension of a fragmented packet allows the reliable detection of a collision by
all stations attached to the network.
Collision Handling
The EtheRx hub will detect and respond to collision conditions as outlined in
the IEEE 802.3 specifications.

Design Features
5
Automatic Partitioning/Reconnection
If any of the ports on the EtheRx hub experience excessive collisions, duration
collisions, or faulty conditions, that particular port can be partitioned. Once
partitioned, the hub will continue to monitor that port. If the error conditions
have been corrected or a good data packet is received without a collision, the
hub will automatically reconnect that port to the network.
Link Test
For UTP port connections, the EtheRx hub implements the link integrity test
function as specified in the IEEE 802.3 10BASE-T standard. The hub will
transmit link test pulses to any UTP port after that port’s transmitter is inactive
for a range of 8ms to 17ms. These pulses are sent to confirm that a valid
connection exists between each UTP port on the hub and its attached device.

For 16-Port models only. The two-color LED displays two states of operation
for the Activity and Partition status on the AUI port. When data is received,
the LED will flash green. If the port has been partitioned due to excessive
collision or other faulty condition, it will display solid red.
Note: Upon power up, the AUI port LED will not be lit unless a transceiver is
attached to the port and there is activity.
BNC LED
The two-color LED displays the Activity and Partition status on the BNC port.
When data is received, the LED will flash green. If the port is partitioned due
to excessive collision or other faulty condition, it will display solid red.
Note: Upon power up, if the BNC port has no cable attached or is not properly
terminated at both ends, the LED will display red to show the port has been
partitioned. Upon receipt of good packets, the LED will automatically change
from red to green indicating that the port is functioning properly.

Hardware Installation
8 or 16 UTP Port LEDs
The LINK/ACTIVITY/PARTITION LEDs use two colors to display three
states of operation for the 8 or 16 UTP ports. If a good link is established on
any given port, the green LED will be continuously lit, indicating a valid
network connection between the network node and the hub. When data is
received, the LED will flash green. A flash may be longer or shorter
depending on the length of the data packet being received. If the port is
partitioned, it will display solid red.
If the LED does not display solid green indicating a good link, check the
following:
1. Make sure the power is turned on for both the PC
and EtheRx hub. The power LED should be lit.
2. Verify the network adapter has loaded its drivers from the
PC. Some network adapters require the drivers to be loaded
to establish a proper link.
3. Make sure the correct cable type is selected.
4. Make sure the cable is wired properly and connected
on both ends.
5. If steps 1, 2, 3, and 4 are correct, the cable may be
defective or not wired correctly. Replace the cable and try
again. Please refer to Appendix A for pin assignments and
Appendix B for cabling guidelines.
Cascade Switch
The Cascade Switch provides cable wiring flexibility on the last UTP Port (i.e.,
Port 8 or Port 16) for connecting to a workstation or cascading to another hub.
By default, the last UTP port is set to “Crossover” (left side) as a standard,
internally-crossed port, or MDI-X port. Depending on the wiring of your UTP
cable (normally “Straight-Through”), the port is used to connect a workstation.
For cascading to another hub using a straight-through cable, move the Cable
Switch to “Straight-Through” (right side). If a crossover UTP cable is used to
cascade to another hub, leave the Cable Switch in the “Crossover” position.
See Figure 1-3 for a diagram showing the 16-Port KNE16TP/WG model. To
verify the pin wiring of your UTP cable, refer to “Appendix B Cabling
Guidelines” on page 17.

Fig. 1-4 Cable Switch functions
Notes on MDI and MDI-X Ports
MDI (Media Dependent Interface) is the IEEE 10BASE-T standard for the
interface to the UTP cable. For two 10BASE-T devices to communicate with
each other, the transmitter of one device must be connected to the receiver of
the other device. This can be achieved by using a crossover cable, or by using
one MDI-X port that implements the cross-over internally.
Port 1 through Port 7 (or 15), like all normal hub ports, are configured MDI-X.
All NICs (Network Interface Cards) and Router ports are usually by default
configured MDI. A simple illustration shows the relationship of cable types to
port types:

BNC Port
This port is labeled BNC, and has a built-in transceiver for direct 10BASE2
connection via thin coaxial cable. Use RG-58 A/U or RG-58 C/U type cable.
Refer to Appendix B for 10BASE2 cabling guidelines when connecting to this
port.
AUI Port
On 16-Port Models only. The AUI port is a 15-pin D-sub connector. It is a
general purpose port for backbone or mixed media connections for 10BASE2,
10BASE5, 10BASE-T, or FOIRL connections using a proper external
transceiver.
8 or 16 UTP Ports
The UTP ports are numbered 1 through 8 or 1 through 16 for 10BASE-T
connections. Since crossover function is implemented on all UTP MDI-X
ports, a straight-through UTP cable should be used. Note: Port 8 and Port 16
support both cable types using the Cable Switch. Refer to Appendix B for
details on RJ-45 pin assignments and cable specifications.
3-Pin AC Power Jack
The EtheRx hub gets its power from the accompanying AC power transformer.
Insert the 3-pin power cable connector into the AC power jack at far right. For
safety purposes, please use ONLY the included AC power transformer for
proper operation. The wrong type power transformer may cause damage to
both the hub and the power transformer.

Network Configurations
11
Network Configurations
The installation of the EtheRx hub is simple and can be configured for either
the Ethernet Star topology, Linear Bus topology, or vertically stacked (SE
models only), or horizontally cascaded to other Ethernet hubs. For cascading,
please observe the Ethernet 5-4-3 Rule.
Ethernet 5-4-3 Rule
The Ethernet 5-4-3 rule states that the maximum transmission path permitted
between any two stations is:
•
•
•
5 segments
4 repeater sets
3 coax segments. The remaining 2 segments may be linked segments
Ethernet Star Network
The typical network configuration for 10BASE-T Ethernet is a Star Topology,
in which nodes are connected to a central Ethernet hub. Since a Crossover
function is implemented on all ports (except the last UTP port which uses a
Cable Switch to support both cable types), a Straight-Through UTP cable
should be used. The physical network connection is illustrated in Figure 3-1.

Network Configurations
Linear Bus Network
The typical network configuration for 10BASE2 networks is a Linear Bus
topology in which nodes are connected to the BNC connector via a thin coaxial
cable. This configuration allows 10BASE2 nodes to communicate with a
10BASE-T segment. A BNC 50Ω (Ohm) terminator must be attached to each
end of the trunk segment. One of the terminators must be grounded. The
purpose of the terminators is to terminate the network and block electrical
interference.

Horizontal Cascading
The EtheRx hubs can be horizontally cascaded to other hubs as long as the
Ethernet 5-4-3 Rule is met (Refer to page 11). This connection can be made
through the BNC port, AUI port (16-Port models only), or one of the UTP
ports. To cascade to another hub, use the last UTP port which has a cascade
switch to support either straight through or crossover cable types. Figure 3-3
below is an example of horizontal cascading using the KNE16TP/WG under
the Ethernet 5-4-3 rule.

Stacking EtheRx SE Hubs
The EtheRx SE hubs use stacking ports located on the front panel to stack up to
five SE hubs in any combination of 8-Port KNE8TP/SE and the 16-Port
KNE16TP/SE models. Follow the directions below to stack up to five SE hubs
together:
1. Locate the 5.5” shielded twisted-pair cable included with your
package contents.
2. Plug one end of the cable into the port labeled, “Stack Out” on the
first hub.
3. Plug the other end of the cable into the “Stack In” port on the second
hub.
4. Connect power to each hub using the external AC power transformer
included with your package contents.
5. Repeat the process to stack additional hubs up to a maximum of five
(5) hubs.
Figure 3-4 below illustrates the stacking cable connections for five 8-Port
KNE8TP/SE hubs expanding the total number of UTP port connections from 8
to 40 UTP ports and still be recognized as one Ethernet repeater on the
network. A maximum of five (5) SE hubs can be stacked in any combination of
8 and 16-Port SE hub models.

UTP Cable Wiring
10BASE-T unshielded twisted-pair cables can be wired as "Straight-Through"
or, in some cases, "Crossover" depending on the application. For workstations
connected to a hub, use "Straight-Through' wiring illustrated in Table B-2. In
some instances, you may want to use "Crossover" wiring illustrated below in
Table B-3.

Appendix B Cabling Guidelines
Cable Wiring Standards
There are two governmental agencies: the Electronic Industry Association
(EIA) and the Telecommunications Industry Association (TIA), which set the
standard for all cable wiring requirements for commercial buildings. For
unshielded twisted-pair (UTP) cabling, Category (CAT) 3, 4 or 5 can be used.
With the advent of 100Mbit network products, it is best to use higher quality
CAT 5 cables like Belden or Helix as well as CAT 5-compliant patch panels
and connectors while following the EIA/TIA wiring standards. 100 Ohm
UTP/STP CAT 3, 4 & 5 type cables use 4-pair UTP wiring. Standard 10BASE-
T uses 2-pair UTP wiring.
Refer to the illustrations below for standard 2-pair 10BASE-T wiring (see Fig
B-4), and 4-pair 100Mbit wiring using either T568A (Fig. B-5) or T568B (Fig.
B-6) wiring standards. Both T568A and T568B wiring is compatible with
10BASE-T and require no special configurations, but mixing the T568A and
T568B wiring schemes will not work.
