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:

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.  
Kingston Technology Company  
EtheRx User’s Guide - Rev. B00  
 
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.

AUI LED  
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.

Using a Straight-Through Cable  
Using a Crossover Cable  
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 50(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.

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.
