FCC STATEMENT

FEDERAL COMMUNICATIONS COMMISSION

RADIO FREQUENCY INTERFERENCE STATEMENT

This equipment generates, uses, and can radiate 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 communication.
It 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 against
such interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is likely to
cause interference, in which case the user at his own expense will be required
to take whatever measures may be necessary to correct the interference.

Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.

This digital apparatus does not exceed the Class A limits for Radio noise emission from
digital apparatus set out in the Radio Interference Regulation of IndustryCanada.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le
brouillage radioélectrique édicté par Industri Canada.

MODULAR PARALLEL ADAPTERS AND MODULAR MEDIA UNITS

2. Introduction

2.1 Available Models

The following models of the
Adapters and the Media Units are
available:

Modular Parallel Adapters:

• LE071A: Modular Parallel
Adapter w/SPC for 10BT

• LE072A: Modular Parallel
Adapter w/SPC for BNC

• LE073A: Modular Parallel
Adapter w/EPS for 10BT

• LE074A: Modular Parallel
Adapter w/EPS for BNC

• LE075A: Modular Parallel
Adapter w/EPS for AUI

Modular Media Units:

• LE171: Modular Media Unit EN­10T

• LE172: Modular Media Unit EN­BNC

• LE175: Modular Media Unit EN­AUI

NOTE

If you would like to connect
both the network and a
printer to your parallel port,
you might want to order the
Modular Parallel Mux
(LE170).

The Modular Parallel Adapter easily
connects notebook, laptop, and
desktop PCs to virtually any Ethernet
Local Area Network. It connects
externally to a standard parallel
printer port, eliminating the need to
install internal Ethernet cards. The
adapter is easy to install; there are
no jumpers or configuration
switches to set. The device is the
perfect solution for notebook and
laptop connectivity, as well as for
workstations with a limited number
of internal expansion slots. The
Adapter fits all Ethernet cable types.

The modular construction of the
Adapter enables you to work with all
three cabling systems used in
Ethernet networks. You simply
attach the Modular Media Unit that
matches your cabling system to the
Adapter and then connect to the
network.

3. Installation

IMPORTANT!

Make sure the computer is
turned off while performing
the install procedure.

3.1 Attach the Media Unit

To attach the Media Unit to the
Adapter, hold the Adapter with the
logo facing up, press the top and
bottom of the unit together, and
insert it until it snaps into the
Adapter (see Fig. 3-1).

Follow these steps to install your
Adapter. Detailed instructions
appear in Sections 3.1 through 3.4.

1. Attach the media unit.

2. Connect the network cable.

3. Plug the Ethernet adapter into
the computer.

4. Install the Self-Powering Cable
or an AC power adapter.

Fig. 3-1. Attaching a Media Unit to the Adapter.

NOTE

If you have purchased a media unit additional to that supplied with the
Adapter, remove the supplied unit by pressing the top and bottom
together and pulling it out of the Adapter. Then, insert the new media unit
as described above.

CHAPTER 3: Installation

3.2 Connect the Network Cable

Connect the network cable unit as
illustrated for each model below.

3.2.1 LE071A

AND

Unit.

NOTE

When used with non­10BASE-T networks, Link
Integrity should be disabled.
It can be disabled in the
software by using the key­word DISABLELINK in the
configuration files (NET.CFG,
PROTOCOL.INI) or as a com­mand line parameter for the
Packet and LANtastic
drivers.
