1.4 SAFETY WHEN WORKING WITH ELECTRICITY
WARNING
•This device contains no user serviceable parts. This
device can only be repaired by qualified service person-
nel.
•Do not open the device when the power cord is con-
nected. For systems without a power switch and without
an external power adapter, line voltages are present
within the device when the power cord is connected.
•For devices with an external power adapter, the power
adapter shall be a listed Limited Power Source. The
mains outlet that is utilized to power the device shall be
within 10 feet (3 meters) of the device, shall be easily
accessible, and protected by a circuit breaker in compli-
ance with local regulatory requirements.
•For AC powered devices, ensure that the power cable
used meets all applicable standards for the country in
which it is to be installed.
•For AC powered devices which have 3 conductor power
plugs (L1, L2 & GND or Hot, Neutral & Safety/Protective
Ground), the wall outlet (or socket) must have an earth
ground.
•For DC powered devices, ensure that the interconnecting
cables are rated for proper voltage, current, anticipated
temperature, flammability, and mechanical serviceability.
•WAN, LAN & PSTN ports (connections) may have hazard-
ous voltages present regardless of whether the device is
powered ON or OFF. PSTN relates to interfaces such as
telephone lines, FXS, FXO, DSL, xDSL, T1, E1, ISDN,
Voice, etc. These are known as “hazardous network volt-
ages” and to avoid electric shock use caution when
working near these ports. When disconnecting cables for
these ports, detach the far end connection first.
•Do not work on the device or connect or disconnect
cables during periods of lightning activity.
In accordance with the requirements of council directive 2002/
96/EC on Waste of Electrical and Electronic Equipment
(WEEE), ensure that at end-of-life you separate this product
from other waste and scrap and deliver to the WEEE collection
system in your country for recycling.
WARNING
This device contains no user serviceable parts. This
device can only be repaired by qualified service personnel.

WARNING
This device is NOT intended nor approved for connection
to the PSTN. It is intended only for connection to customer
premise equipment.
CAUTION
Electrostatic Discharge (ESD) can damage equipment and
impair electrical circuitry. It occurs when electronic printed cir-
cuit cards are improperly handled and can result in complete or
intermittent failures. Do the following to prevent ESD:
Page 10 724-746-5500 | blackbox.com
Black Box LB200A-R4 User Manual
•Always follow ESD prevention procedures when removing
and replacing cards.
•Wear an ESD-preventive wrist strap, ensuring that it makes
good skin contact. Connect the clip to an unpainted surface of
the chassis frame to safely channel unwanted ESD voltages
to ground.
•To properly guard against ESD damage and shocks, the wrist
strap and cord must operate effectively. If no wrist strap is
available, ground yourself by touching the metal part of the
chassis.

• Auto-MDIX Ethernet
• Configurable 10/100, Full/Half, and Auto-Negotiating Ethernet
• Extends up to 1 or 2 10/100Base-TX Ethernet beyond 328-foot (100-meter) limitation over a single
twisted-pair, Cat 5e/6/7, or coaxial cable
• Variable line rate settings via DIP switch
• Transparent operation
• LED indicators for Power, Line, Local, Remote, Ethernet 0 and 1 (Eth 0 and Eth 1), and Ethernet Link/

2.2 DESCRIPTION
BlackBox LB200A-R4 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, one LB200A-R4 is configured as the (L) Local unit located at one end of the LAN exten-
sion and the other LB200A-R4 is configured as the (R) Remote unit at the other end. The LB200A-R4 is
configured as an L or R via the switch on the bottom of the unit. These units can automatically forward LAN
broadcasts, multicasts, and frames across a 2-wire voice-grade twisted-pair or BNC link. The data is
passed transparently (unmodified) through the LB200A-R4. The LB200A-R4s automatically add and delete
MAC addresses, only passing packets across the Line link that are meant for the remote peered LAN.
Figure 1. Typical applications
The pair of LB200A-R4 models work together to create a transparent extension between two peered Ether-
net LANs using twisted pair (2-wire) or Cat5+. Figure 1 shows typical applications.

To install the LB200A-R4 Ethernet Extender, do the following:
1. Connect the line interface between the units (refer to “Connecting the Line Interface” on page 14)
Note See Figure 2 for the LB200A-R4’s rear panel.
2. Connect the Ethernet interface (refer to “Connecting the 10/100Base-T Ethernet Interface” on
page 15).
3. Connect the power plug (refer to “Connecting Power” on page 16).

3.2 CONNECTING THE LINE INTERFACE
CAUTION
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
The LB200A-R4 supports communication between two peer Ethernet LAN sites over a distance of up to
10,000 ft (3 km) over 24 AWG (0.5 mm) twisted-pair wire, Cat5+, or 75-ohm BNC.
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 LB200A-R4 interfaces.
Note The LB200A-R4 units work in pairs. One of the units must be configured as a (L) Local unit,
and the other unit must be configured as a (R) Remote unit.
The Interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.

Installation
3.3 CONNECTING THE LINE INTERFACE FOR LB200A-R4
1. To function properly, the two LB200A-R4s must be connected together using twisted-pair, uncondi-
tioned, 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 LB200A-R4 is equipped with an RJ-45 interface jack (Figure 3)
The RJ-45 connector on the LB200A-R4’s twisted pair interface is polarity insensitive and is wired for a two-
wire interface. The signal/pin relationship is shown in Figure 3.

CAUTION
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
The RJ-45 ports labeled Eth 0 and Eth 1 are Auto-MDIX 10/100Base-T interfaces. These ports are
designed to connect directly to a 10/100Base-T device or network. Figure 4 shows the signal/pin relation-
ships 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.

3.5 CONNECTING POWER
CAUTION
The interconnecting cables shall be acceptable for external use
and shall be rated for the proper application with respect to volt-
age, current, anticipated temperature, flammability, and
mechanical serviceability.
The LB200A-R4 does not have a power switch, so it powers up as soon as it is plugged in.
An external AC or DC power supply is available separately. This connection is made via the barrel jack on
the rear panel of the LB200A-R4. No configuration is necessary for the power supply.
DC power (supplied via the power supply jack to the LB200A-R4) must meet the following requirements;
DC power supplied must be regulated 5 VDC ±5%, 1.0A minimum. Center pin is +5 V. The barrel type plug
has 2.5/5.5/10mm I.D./O.D./Shaft Length dimensions.
