• LE071A: Modular Parallel

Adapter w/SPC for 10BT

• LE072A: Modular Parallel

Adapter w/SPC for BNC

• LE073A: Modular Parallel

Adapter w/EPS for 10BT

Modular Media Units:

• LE171: Modular Media Unit EN-

10T

• LE172: Modular Media Unit EN-

BNC

• LE175: Modular Media Unit EN-

AUI

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.

Unit.

NOTE

When used with non-

10BASE-T networks, Link

Integrity should be disabled.

It can be disabled in the

software by using the key-

word DISABLELINK in the

configuration files (NET.CFG,

PROTOCOL.INI) or as a com-

mand line parameter for the

Packet and LANtastic

drivers.

3.2.2 LE072A

AND

LE074A

For the Modular Parallel Adapters

for BNC (LE072A and LE074A),

refer to Fig. 3-3.

Fig. 3-3. Connecting an RG-58/U Coaxial Cable to the Media Unit.

Make sure that the RG-58A/U

coaxial cable has a T-connector at

the end. Then connect the T-

connector to the BNC connector at

the back of the media unit, as shown

in Fig. 3-3.

CHAPTER 3: Installation

NOTE

Both ends of the T-

connector must be attached

to network cabling. If the

Adapter is at the end of a

network segment, the end of

the T-connector not attached

to the network must have a

50-ohm terminator installed.
