free from defects, and will—at our option—repair or replace the product
should it fail within one year from the first date of shipment.
This warranty is limited to defects in workmanship or materials, and
does not cover customer damage, abuse or unauthorized modification.
If this product fails or does not perform as warranted, your sole recourse
shall be repair or replacement as described above. Under no condition
shall Patton Electronics be liable for any damages incurred by the use
of this product. These damages include, but are not limited to, the
following: lost profits, lost savings and incidental or consequential
damages arising from the use of or inability to use this product. Patton
Electronics specifically disclaims all other warranties, expressed or
implied, and the installation or use of this product shall be deemed an
acceptance of these terms by the user.
1.1 RADIO AND TV INTERFERENCE
The Model 2100LC generates and uses radio frequency energy,
and if not installed and used properly—that is, in strict accordance with
the manufacturer’s instructions—may cause interference to radio and
television reception. If the Model 2100LC does cause interference to
radio or television reception, which can be determined by disconnecting
the power supply, the user is encouraged to try to correct the
interference by one or more of the following measures: moving the
computing equipment away from the receiver, re-orienting the receiving
antenna and/or plugging the receiving equipment into a different AC
outlet (such that the computing equipment and receiver are on different
branches).
1.2 SERVICE
All warranty and non-warranty repairs must be returned freight
prepaid and insured to Patton Electronics. All returns must have a
Return Materials Authorization number on the outside of the shipping
container. This number may be obtained from Patton Electronics
Technical Service at [phone].
Packages received without an
RMA number will not be accepted.
Patton Electronics’ technical staff is also available to answer any
questions that might arise concerning the installation or use of your
Model 2100LC. Technical Service hours: 8AM to 5PM EST, Monday
through Friday.

2.1 FEATURES
• Adapts an Ethernet AUI port to a 10BaseT UTP interface
• Compatible with IEEE 802.3 specifications
• Supports distances to 300 feet
• No AC power or batteries required
• Plugs directly into the AUI port
• Easy to install and operate
• Made in USA
2.2 DESCRIPTION
The Patton Model 2100LC is a low-cost 10BaseT tranciever/MAU
that allows Ethernet AUI ports to communicate over twisted pair cable
at distances up to 300 feet. Deriving power from the AUI interface, the
Model 2100LC requires no AC power or batteries. It can be connected
directly to a PC AUI port via a male DB-15 and to two twisted pair wire
via an RJ-45 jack. The Model 2100LC is housed in a sturdy ABS
plastic case measuring only 2” long x 1.68” wide 0.79” high.
Connecting directly to a DB-15 Ethernet AUI port, the Model
2100LC converts the 802.5 Ethernet electrical signals into signals that
are compatible with the 802.3 twisted pair interface. The Model
2100LC then transmits this data back to the workstation. To ensure
accuracy, an easily accessible SQE (Signal Quality Error) switch
automatically detects and corrects any misread signals. In addition, the
Model 2100LC will automatically correct a reversed polarity condition,
and cease transmission if it detects a jabber condition.

3.0 INSTALLATION
The Model 2100LC can be connected to either the AUI port or the
10BaseT hub. Section 3.1 describes how to connect the Model
2100LC to an AUI port; Section 3.2 describes how to connect the Model
2100LC to the 10Base10 hub.
3.1 CONNECTION TO THE AUI PORT
1. Turn off the computer or device to which the Model 2100LC is
to be connected.
2. If the Model 2100LC is to be connected to the AUI port of an
Ethernet interface card, turn the SQE switch ON. If the Model
2100LC is to be connected to the AUI port of an Ethernet hub
or repeater, turn the SQE switch OFF.
3. Open the slide latch of the AUI port and insert the Model
2100LC into the DB-15. Lock the slide latch to secure the
Model 2100LC in place. If the AUI port is mounted to a card,
make sure the card is configured correctly so the AUI port will
be enabled.
Note: If your AUI port connection is through a DB-15 cable,
make sure the cable is wired STRAIGHT THROUGH, with at
least the following signals being passed:
AUI PORT MODEL 2100LC
Signal Pin # Pin # Signal
Data Out(+) 3 ------------------3 Data Out+
Data Out(-) 10-----------------10 Data Out-
Data In(+) 5 ------------------5 Data In+
Data In(-) 12-----------------12 Data In-
Collision In(+) 2 ------------------2 Collision In+
Collision In(-) 9 ------------------9 Collision In-
3.2 CONNECTION TO THE 10BASET HUB
To connect the Model 2100LC to a 10BaseT hub, use an
unshielded twisted pair cable—terminated with RJ-45 plugs—wired
STRAIGHT THROUGH in the following manner:
MODEL 2100LC 10BASETHUB
Signal Pin # Pin # Signal
Transmit(+) 1----------------------1 Transmit(+)
Transmit(-) 2----------------------2 Transmit(-)
Receive(+) 3----------------------3 Receive(+)
Receive(-) 6 ----------------------6 Receive(-)

4.0 OPERATION
The Model 2100LC does not require any configuration or AC
power, and its operation is completely transparent.
During operation, the Model 2100LC receives electrical signals
from the 802.5 Ethernet. This transmission is then “double checked”:
the SQE feature sends a pulse back to the Ethernet to verify that all
signals were received correctly. After verification, the Model 2100LC
converts the original signals into new signals that are compatible with
the 802.3 twisted pair interface. The new signals are then transmitted
back to the workstation.
If the Model 2100LC is connected to an interface card, the SQE
feature should be enabled (switch ON). If the Model 2100LC is
connected to a hub or repeater, the SQE switch should be OFF.
APPENDIX A
SPECIFICATIONS
Standard: IEEE 802.3 compliant
Connectors: DB-15 male on AUI port, RJ-45 jack on
10BaseT twisted pair port
Link Parameters:
Duration between transmit link pulses: 8ms(min)/24ms(max)
Duration between receive link pulses: 3ms(min)/105ms(max)
Collision Parameters:
Collision signal ON/OFF delay (CI+/-): 900ns(max)
