1.0 WWARRANTY IINFORMATION

Patton Electronics warrants all Model 2112 components to be

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 2112 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. The Model 2112 has been tested and found to com­ply 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 interfer­ence will not occur in a particular installation. If the Model 2112 does
cause interference to radio or television reception, which can be deter­mined by disconnecting the unit, 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 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 2112-CO and 2112-CP 100-User

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 3.6 miles away!

Operating in pairs with a Model 2112-CO (looks like Central Office
equipment) on one end and a Model 2112-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 2112s 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 2112s without
modification.
