KTI Networks KT-10T Merkblatt

• 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)

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:

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:

1

Outgoing Data 1 (+)

2

Outgoing Data 2 (-)

3

Incoming Data 1 (+)

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.

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.

The KT-10T Ethernet transceiver complies with IEEE
802.3 transceiver 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.
