UTP connection: RJ45 Jack
Category 3,4, or 5 UTP 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.
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:

Setting Switches
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:
General Description
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.
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.

SW1 ON
SW1 OFF
SW2 ON
Function
Enable SQE test (factory default)
Disable SQE test (for repeater device)
Enable Link test (factory default)
Disable Link test
The transceiver is attached to the AUI connector of an
Ethernet device via standard AUI cable.
SW2 OFF
Pin Assignments of the AUI (DB15) Connector
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.
