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
(

. This CopperLink interface is a two-wire interface. Observe the
signal/pin relationships on the CopperLink Ethernet Extender's Cop-
perLink interface jack.
