1.1 RADIO AND TV INTERFERENCE (FCC PART 15)
This equipment generates and uses radio frequency energy, and if not
installed and used properly—that is, in strict accordance with the manu-
facturer's instructions—may cause interference to radio and television
reception. This equipment has been tested and found to comply with the
limits for a Class A computing device in accordance with the specifica-
tions in Subpart B of Part 15 of FCC rules, which are designed to provide
reasonable protection from such interference in a commercial installa-
tion. However, there is no guarantee that interference will not occur in a
particular installation. If the equipment causes interference to radio or
television reception, which can be determined by disconnecting the
cables, 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).

WARNING
• This device contains no user serviceable parts. The
equipment shall be returned to Patton Electronics for
repairs, or repaired by qualified service personnel.
• Ensure that the power cable used meets all applica-
ble standards for the country in which it is to be
installed, and that it is connected to a wall outlet
which has earth ground. The mains outlet that is uti-
lized to power the devise shall be within 10 feet (3
meters) of the device, shall be easily accessible, and
protected by a circuit breaker.
• Do not work on the system or connect or disconnect
cables during periods of lightning activity.
• Hazardous network voltages are present in WAN
ports regardless of whether power to the unit is ON or
OFF. To avoid electric shock, use caution when near
WAN ports. When detaching the cables, detach the
end away from the device first.
WARNING
The Interconnecting cables shall be acceptable for
external use and shall be rated for the proper applica-
tion with respect to voltage, current, anticipated tem-
perature, flammability, and mechanical serviceability
In accordance with the requirements of council direc-
tive 2002/96/EC on Waste of Electrical and Electronic
Equipment (WEEE), ensure that at end-of-life you sepa-
rate this product from other waste and scrap and deliver
to the WEEE collection system in your country for recy-
cling.

2.2 DESCRIPTION
The Patton Electronics CopperLink/L and EnviroNET CopperLink/R
Ethernet Extenders provide high-speed LAN connections between
peered Ethernet LANs, remote PCs, or any other network enabled
10/100Base-T device.
Operating in pairs, a CopperLink/L (local) located at one end of the LAN
extension and the EnviroNET CopperLink/R (remote) at the other end,
these units can automatically forward LAN broadcasts, multicasts, and
frames across a 2-wire voice-grade twisted-pair link. The data is passed
transparently (unmodified) through the CopperLink Ethernet Extenders.
The CopperLink Ethernet Extenders automatically add and delete MAC
addresses, only passing packets across the CopperLink link that are
meant for the remote peered LAN.

Figure 1. Typical application
The CopperLink/L modem and EnviroNET CopperLink/R modem work
together to create a transparent extension between two peered Ethernet
LANs. Figure 1 shows a typical point-to-point application.

3.0 INSTALLATION
Because the EnviroNET CopperLink Ethernet Extender requires no configu-
ration, it can be installed quickly.
3.1 UNIT INSTALLATION
Do the following:
1. Make a ground connection for the unit (refer to section 3.2, “Ground-
ing the EHA2168” on page 9).
2. Connect the line interface between the units (refer to section 3.3,
“Connecting the Twisted-Pair Line Interface” on page 9)
Note See Figure 2 for the EHA2168 unit’s bottom panel arrange-
ments.
3. Connect the Ethernet interface (refer to section 3.4, “Connecting the
10/100Base-T Ethernet Interface” on page 10).
4. Connect the power plug (refer to section 3.5, “Connecting Power” on
page 11).

3.2 GROUNDING THE EHA2168
Before installing the EnviroNET CopperLink Ethernet Extender, it is
important to establish a good grounding connection first.
1. Assemble a ground wire using #10 AWG wire with green-and-yel-
low-colored insulation and two ring terminals. Make the wire long
enough to reach one of the following earth ground sources:
— The building ground rod (generally located at the site’s main
service entrance)
— A sprinkler system pipe
— A cold-water pipe
— Building structural steel
2. Install the grounding wire between the grounding stud (see Figure 2
on page 8) and the grounding source.
3.3 CONNECTING THE TWISTED-PAIR LINE INTERFACE
The EnviroNET CopperLink Ethernet Extender supports communication
between two peer Ethernet LAN sites over a distance of up to 4,000 ft
(1.22 km) over 24 AWG (0.5 mm) twisted-pair wire.
Note Actual distance and link performance may vary depending on
the environment and type/gauge of wire used.
Follow the steps below to connect the CopperLink Ethernet Extenders
interfaces.
Note The CopperLink units work in pairs. One of the CopperLink units
must be an L (local), and the other unit must be an R (remote). It
does not matter which end is the L and which is the R.The link is
always initiated by the R. As long as the L is powered on, the R
can establish a link by being powered on or by having its power
reset.
1. To function properly, the two CopperLink Ethernet Extenders must
be connected together using twisted-pair, unconditioned, dry, metal
wire, between 19 (0.9mm) and 26 AWG (0.4mm). Leased circuits
that run through signal equalization equipment are not acceptable.
2. The EnviroNET CopperLink Ethernet Extender is equipped with an
RJ-45 interface jack that can be used on the CopperLink interface
(
Line ) . This CopperLink interface is a two-wire interface. Observe the
signal/pin relationships on the CopperLink Ethernet Extender's Cop-
perLink interface jack.

10
The RJ-45 connector on the CopperLink Ethernet Extender's twisted
pair interface is polarity insensitive and is wired for a two-wire inter-
face. The signal/pin relationship is shown in Figure 3.
Figure 3. CopperLink Ethernet Extender (RJ-45) twisted pair line interface.
3.4 CONNECTING THE 10/100BASE-T ETHERNET INTERFACE
The unshielded RJ-45 port labeled Data on the EHA2168 model is the
Auto-MDIX10/100Base-T interface. This port is designed to connect
directly to a 10/100Base-T network. Figure 4 shows the signal/pin rela-
tionships on this interface.You may connect this port to a hub or PC
using a straight through or crossover cable that is up to 328 ft long.
