Ethernet 10Base-T Transceiver

Model: KT-10T

DOC. G509282-KT10T

General Description

The KT-10T Ethernet transceiver complies with IEEE

802.3transceiver specifications and 10Mbps Ethernet CSMA/CD operation to provide a connection interface to 10Base-T Ethernet Unshielded Twisted-Pair (UTP) cable.

The transceiver is attached to the AUI connector of an Ethernet device via standard AUI cable.

Features

•Provides a complete interface of the AUI to Ethernet UTP cable (IEEE 802.3 10Base-T).

•Supports data transfer rate of 10Mbps.

•CSMA/CD access mechanism

•Capability for driving the UTP cable segment up to 100M (328 ft.) without the use of a repeater.

•Selectable Link test and SQE test functions

•The RJ45 jack can detect and correct the wiring polarity reverse on the receiving pair of the UTP cable automatically.

•Supports LED indications for the Power, Transmit, Link, Receive, Collision, and Polarity reversal status.

• Dimension: 42mm x 65mm x 20mm

•Input voltage: 10.2 to 15.75 VDC

•Input current: 250mA @12 VDC (typical)

Connectors & Cables

AUI connection: D-sub 15 pin male connector AUI drop cable (50 meters max.)

The AUI connector is used for attaching the transceiver to the AUI port provided by an Ethernet device such as an Ethernet MAC controller, an Ethernet repeater, or an Ethernet concentrator via an AUI drop cable. The pin assignments are shown as below:

Pin Assignments of the AUI (DB15) Connector

Pin	Name	Pairs	Use
3	DO +	Transmit	Data Out (+)
10	DO -	Pair	Data Out (-)
11	DO S		Data Out Shield
5	DI +	Receive	Data In +
12	DI -	Pair	Data In -
4	DI S		Data In Shield
7	CO +	Optional	Control Out +
15	CO -	Pair	Control Out -
8	CO S		Control Shield
2	CI +	Collision	Control In +
9	CI -	Pair	Control In -
1	CI S		Control Shield
6	VC	Power	Voltage Common
13	VP	Pair	Voltage Plus
14	VS		Voltage Shield

UTP connection: RJ45 Jack

Category 3,4, or 5 UTP cable

The 10Base-T RJ45 OUT jack is used for connecting to a 10Base-T Ethernet hub via a 2-pair UTP cable. The length of the UTP cable can be up to 100 meters. The jack pin assignments are listed as below:

8(No connection)

Setting Switches

Two switches are provided for setting the options of disabling the SQE test function and LINK test function. Both test functions are Ethernet and 10Base-T standard.

Switch Setting	Function
SW1 ON	Enable SQE test (factory default)
SW1 OFF	Disable SQE test (for repeater device)
SW2 ON	Enable Link test (factory default)
SW2 OFF	Disable Link test

The transceiver is shipped from the factory with the SQE test enabled. Depending on the Ethernet device to which the AUI connector attaches, you can set the SW1 switch to "OFF" position to disable the SQE test function or set the switch to "ON" position to enable the SQE test function.

If the transceiver is connected to an Ethernet repeater, a 10Base-T hub, or a wiring concentrator, the SQE test function should be disabled.
