1.0 WWARRANTY IINFORMATION
Patton Electronics warrants all Model 2111 components to be
free from defects, and will—at our option—repair or replace the prod-
uct 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 modifi-
cation. 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 consequen-
tial 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 2111 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 tele-
vision reception. The Model 2111 has been tested and found to com-
ply with the limits for a Class A computing device in accordance with
the specifications in Subpart J of Part 15 of FCC rules, which are
designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that interfer-
ence will not occur in a particular installation. If the Model 2111 does
cause interference to radio or television reception, which can be deter-
mined by disconnecting the unit, the user is encouraged to try to cor-
rect the interference by one or more of the following measures: mov-
ing the computing equipment away from the receiver, re-orienting the
receiving antenna and/or plugging the receiving equipment into a differ-
ent AC outlet (such that the computing equipment and receiver are on
different branches).
1.2 CE NOTICE
The CE symbol on your Patton Electronics equipment indicates
that it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the European Union
(EU). A Certificate of Compliance is available by contacting Technical
Support.

2.2 DESCRIPTION
The Patton Electronics Model 2111-CO and 2111-CP Ethernet
LAN Bridge Extenders provide seamless LAN extension between
peered Ethernet LANs with all of the benefits of MAC level bridging.
You already own the twisted pair, why not use it to forward Ethernet
data to another Ethernet LAN -- up to 5 miles away!
Operating in pairs with a Model 2111-CO (looks like Central Office
equipment) on one end and a Model 2111-CP (looks like Customer
Premises equipment) on the other end, can automatically forward LAN
broadcasts, multi-casts and frames across the 2-Wire twisted pair link.
What’s more, the 2111s automatically add and delete MAC addresses,
only passing packets across the twisted pair that are meant for the
remote peered LAN. Higher level protocols such as TCP/IP, DECnet,
NETBIOS and IPX pass transparently through the Model 2111s without
modification.
WARNING! This device is not intended to be con-
nected to the public telephone network.
NOTE: Packages received without an RMA number will
not be accepted.

2.3 TYPICAL APPLICATION
The 2111-CO and 2111-CP work together to create an extension
between 2 peer Ethernet LANs with all the benefits of MAC bridging.
The following diagram shows a typical application
3.0 INSTALLATION
The Model 2111 requires no configuration. You only need to con-
nect the Ethernet interface, line interface between the units and power.
This section describes these connections.
3.1 CONNECTING THE TWISTED PAIR LINE INTERFACE
The Model 2111 supports communication between two peer
Ethernet LAN sites at a distance up to 5 miles (8 km) over 24AWG
(.5mm) twisted pair wire. Follow the steps below to successfully con-
nect the Model 2111 Line Interfaces.
1. These units work in
pairs . One unit in the pair must be a
Model 2111-CO (looks like Central Office equipment), and the
other unit must be a Model 2111-CP (looks like Customer
Premises equipment). It does not matter which end is the
2111-CO and which is the 2111-CP.
2. To function properly, the two Model 2111s must be connected
together using twisted pair metallic wire. This twisted pair
must be
unconditioned , dry, metallic wire, between 19
(.9mm) and 26 AWG (.4mm). Standard dial-up telephone cir-
cuits, or leased circuits that run through signal equalization
equipment, or standard, flat modular telephone type cable,
are
not acceptable .

3.2 CONNECTING THE 10BASET ETHERNET INTERFACE
The RJ-45 jack labeled “Interface Port” is the 10BaseT interface.
This port is designed to connect directly to a 10BaseT network. Figure
4, below, shows the Signal/Pin relationships on this interface. You may
connect this port to another Ethernet port via a Type 4 or Type 5 cable
that is up to 330 feet long.
3.2.1 Connecting the 10Base-T Ethernet Port to a Hub
The Model 2111 10Base-T interface is configured as DTE (Data
Terminal Equipment), just like a 10Base-T network interface card in a
PC. Therefore, it “expects” to connect to a 10Base-T Hub using a
straight-through RJ-45 cable. Use the diagram below to construct a
cable to connect the 2111 to a 10Base-T Hub.

The Model 21111 10Base-T interface is configured as DTE (Data
Terminal Equipment). If you wish to connect the 2111 to another DTE
device such as a 10Base-T network interface card in a PC, you must
construct a 10Base-T crossover cable as shown in the diagram below.

3.3 CONNECTING POWER
The Model 2111 is available with a Universal AC power supply
that is operable in power environments from 100 to 253VAC. No con-
figuration is necessary for the power supply (See Appendix B for
domestic and international power plug options).
3.3.1 Connecting to an AC Power Power Source
The Universal Interface AC Supply is equipped with a male IEC-
320 power connection. A domestic (US) power supply cord is supplied
with the unit at no extra charge. To connect the standard or universwal
power supply, follow these steps:
1. Attach the power cord (supplied) to the shrouded male IEC-
320 connector on the rear of the Model 2111.
2. Plug the power cord into a nearby AC power outlet
3. Turn the rear power switch ON.
4.0 OPERATION
Once the Model 2111 is properly installed, it should operate trans-
parently. This sections describes power-up, reading the LED status
monitors, and using the built-in loopback test modes.
4.1 POWER-UP
To apply power to the Model 2111, first be sure that you have read
Section 3.3, and that the unit is connected to the appropriate power
source. Then power-up the unit using the rear power switch.
4.2 FRONT PANEL LED STATUS MONITORS
The Model 2111 features eight front panel LEDs that monitor
power, the Ethernet signals, network connection and test modes.
Figure 4 (below) shows the front panel location of each LED.
Following Figure 4 is a description of each LEDs function.
TD & RD Glows red to indicate an idle condition of Binary
“1” data on the respective terminal interface signals.
Green indicates Binary “0” data.
CTS Glows green to indicate that the Clear to Send
signal from the modem is active.
CD Glows red if no carrier signal is being received from
the remote modem. Green indicates that the remote
modem’s carrier is being received.
DTR Glows green to indicate that the Data Terminal
Ready signal from the terminal is active.
ER Glows red to indicate the likelihood of a Bit Error in
the received signal. During the 511 or 511/E test, ER
will flash to indicate that the Test Pattern Detector
has detected a bit error.

WARNING! There are no user-serviceable parts in
the power supply section of the Model 2111. Voltage
setting changes and fuse replacement should only be
performed by qulified service personnel. Contact
