Setting Switches
General Description
The KT-10F Ethernet transceiver complies with IEEE 802.3
transceiver specifications and 10Mbps Ethernet CSMA/
CD operation to extend the your existing Ethernet segment
up to 2000 meters by using fiber optic cable.
The transceiver is attached to the AUI connector of an
Ethernet device via standard AUI cable.
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
There are two switches which are accessible on the side of
the transceiver enclosure. The functions of these switches
are:
SW# Setting Function
SW1 On Enable SQE test (factory default)
O f f Disable SQE test (for repeater device)
SW2 On Full-duplex mode
O ff Half-duplex mode (factory default)
Important:
The transceiver is shipped from the factory with the SQE
test enabled. If the transceiver is connected to an Ethernet
repeater, a 10Base-T hub, or a wiring concentrator, the SQE
test function should be disabled.
Installation
Interpreting LED Indicators
Attaching to an Ethernet device via an AUI cable
The Ethernet device can be a network interface controller,
wiring concentrator, or repeater that provides an AUI port.
For attaching to such device, an AUI cable of appropriate
length is required. The following figure illustrates the
connection of the transceiver and an Ethernet device via
an AUI cable.
Important:
If the transceiver is attached to an Ethernet repeater, a
10Base-T hub, or a wiring concentrator, the SQE test
function should be disabled.
Connecting to a fiber optic cable segment
The transceiver has two ST female connectors for hooking
up to a duplex fiber optic cable segment. One ST connector is used for transmitting data and the other one is used
for receiving data. Two fiber optic cables are required to
compose a duplex cable segment between the transceiver
and the Fiber Optic port at the other end of the cables.
There are four diagnostic LED indicators provided on the
transceiver to indicate the operation status as below:
LED Operation status State Interpretation
Link Cable link status On The cable link is ok
Off No cable link or the link is
faulty.
Blink The cable link is faulty.
TRX Transmission status Blink Transmission is in operation.
Off No transmission.
On Normal, if large transmission is
in operation.
Problem, if no transmission.
RCV Receiving status Blink Receiving data packet
Off No packet is being received.
On Normal, if heavy traffic load.
Problem, if no network traffic.
COL Collision status Of f No collision occurs.
Blink There is presence of collisions.
The Fiber Optic port at the other end of the cables must
comply with IEEE 802.3 10Base-FL standard.
