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.

MINI 10BASE-T TRANSCEIVER W/CABLE

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 the Canadian

Department of Communications.

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 le

ministère des Communications du Canada.

2.0 Introduction

The Mini 10BASE-T Transceiver w/Cable connects

a host to a 10BASE-T network using your existing

standard Ethernet adapter card. Two models are

available:

• LE3010A, Mini 10BT Transceiver w/Cable

(Slidelock)

• LE3011A, Mini 10BT Transceiver w/Cable

(Screwlock)

Both models include the following:

• Transceiver

• Attached 6-ft. molded office transceiver cable

• Attached 15-ft. 24 AWG stranded UTP wire

3.0 Configuration

3.1 Set SQE Switch

SQE is the Signal Quality Error function that

provides “heartbeat” for network data collision

detection setting. If the host to which the

transceiver is connected is a computer, set the SQE

switch to ON. If the host is a repeater (coaxial

cable use), set the SQE switch to OFF. Fig. 3-1

shows the location of the SQE switch.

4.0 Installation

4.1 Connect the Transceiver to the Host and to the Hub

1. Plug the DB15 connector of the AUI cable

into the host’s DB15 port.

2. Plug the RJ-45 connector of the UTP cable

into the 10BASE-T hub. See Fig. 4-1.

CHAPTER 5: LED Indicators

5.0 LED Indicators

The LED indicators on the transceiver show the

following:

•

POWER/TX

—The indicator should be

constantly ON, once you connect the

transceiver to the host and the hub. When

this indicator blinks, data is being transmitted.

•

LINK/RCV

—When this indicator is

continuosly ON, data link is OK and the

transceiver is ready to receive data. When this

indicator blinks, data is being transmitted.

•

COLLISION

—This indicator should be OFF

most of the time. When it is ON, data

collision is occurring. Data collision is not an

abnormal situation. It may sometimes happen

when the host to which the transceiver is

connected attempts to transmit data on the

network while another host is also attempting

to do the same. When this happens, data

collides on the network. Both hosts will then

back off and attempt to retransmit at random

intervals. The transceiver retries until data

collisions cease.

MINI 10BASE-T TRANSCEIVER W/CABLE

•

JABBER

—This indicator should be OFF

most of the time. When it is ON, the data

transmission function is being interrupted

because of an abnormally long output data

stream. The function is interrupted to

prevent the corrupted data from being sent

over the network.
