1.2 Description

The Multi-Rate Ethernet Extender/L (Local) and Multi-Rate Ethernet Extender/R
(Remote) provide high speed LAN connections between peered Ethernet LANs,
remote PC’s, or any other network enabled 10/100Base-T device.

Operating in pairs, a Multi-Rate Ethernet Extender/L (Local) located at one end
of the LAN extension and a Multi-Rate Ethernet Extender/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 transpar-

7

MULTI-RATE ETHERNET EXTENDER

ently (unmodified) through the Multi-Rate Ethernet Extenders. The Ethernet
Extenders automatically add and delete MAC addresses, only passing packets
across the link that are meant for the remote peered LAN.

Figure 1.

Typical application

The Local and Remote Multi-Rate Ethernet Extenders work together to create a
transparent extension between two peered Ethernet LANs. Figure 1 shows a typi­cal point-to-point application.

2.2 Connecting the Twisted-Pair Line Interface

The Multi-Rate Ethernet Extender supports communication between two peer
Ethernet LAN sites over a distance of up to 6,000 ft (1.83 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 Ethernet Extender interfaces.

Note

The Ethernet Extender units work in pairs. One of the units must be a L
(Local), and the other unit must be a R (Remote). It does not matter
which end is the L and which is the R. The link is always initiated by the
Remote. As long as the Local is powered on, the Remote can establish a
link by being powered on or by having its power reset.

1. To function properly, the two 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 Ethernet Extender is equipped with the LINK interface presented on an
RJ-45. This
relationships on the

LINK

interface is a two-wire interface. Observe the signal/pin

LINK

interface jack. For a terminal block

LINK

inter-

face (LB201A), please contact [e-mail].

The RJ-45 connector on the Ethernet Extender's twisted pair interface is polarity
insensitive and is wired for a two-wire interface. The signal/pin relationship is
shown in Figure 3.

2.3 Connecting the 10/100Base-T Ethernet Interface

The unshielded RJ-45 port labeled

Ethernet

is the Auto-MDIX 10/100Base-T
interface. This port is designed to connect directly to a 10/100Base-T network.
Figure 4 shows the signal/pin relationships 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.

2.4 Connecting Power

An external AC or DC power supply is available separately. This connection is
made via the barrel jack on the rear panel of the Ethernet Extender . No configura­tion is necessary for the power supply (See Appendix A for domestic and interna­tional power supply and cord options).

DC power (supplied via the power supply jack to the Ethernet Extender) must
meet the following requirements; DC power supplied must be regulated +5VDC
±5%, 1.0A minimum. Center pin is +5V. The barrel type plug has a

2.5/5.5/10mm I.D./O.D./Shaft Length dimensions.

•

Connect the equipment to a 5 VDC supply source that is electrically isolated
from the AC source. The 5 VDC source must be reliably connected to earth.

An approved external SELV source—rated a maximum of 5 VDC, 2 A—that

•

incorporates a disconnect device must be used and positioned within easy
reach of the operator’s position.

The Ethernet Extender does not have a po wer switch, so it po wers up as soon as it
is plugged in.

There are no user-serviceable parts in the LB200A
modem. Fuse replacement should only be per­formed by qualified service personnel. Contact
Black Box Technical support at [phone] for
more information.
