This Booklet is designed as a guide for installing and
using the 10 Base 5/T Transceiver on 10Base-T
Ethernet applications
The 10 Base 5/T Transceiver provide both an AUI
connector and RJ-45 modular jack to facilitate direct
connect from the Thick Ethernet Host to 10Base-T
Ethernet network. The Host can be a Thick Ethernet card
or a 10Base-5 repeater.
Set SQE Switch
SQE is the Signal Quality Error function that provides
"Heart Beat" self-test signal. This signal verifies that the
collision detect circuit in the transceiver is operational. 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.

Connect Host to Transceiver
Use AUI port of 10 Base 2/5 transceiver to connect directly
or through an AUI cable (Transceiver drop cable) to Host.
Connect Transceiver to Network
Use a twisted-pair cable for 10Base-T Ethernet to connect
the 10 Base 2/5 Transceiver to Hub.

LED Indicators
The LED indicators on the transceiver show the following:
POWER/TX: The indicator should be continuously ON,
once the transceiver is connected to the Host
and the Hub. When this indicator blinks,
Transmission is occurring.
LINK/RCV: WHEN this indicator is continuously ON, data
link is OK and the transceiver is ready to
receive data. When this indicator blinks, data
transmission is occurring.
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 collision on
the network bus line takes place. Both Hosts
will then back off and attempt to transmit data
at random intervals. This process is retried
until no data collision occurs.

Jabber: This indicator should be OFF most of the time.
When it is ON, data transmission function
is being interrupted due to an abnormally long
output data stream. The function is interrupted
to prevent the corrupted data from being sent
over the network.
