Running
other
diagnostic
tests
In
addition
to
the
three
default tests, TroubleShooter offers
the
Loop-
back
test
and
the
Bandwidth Utilization
test
to
validate
operation
of
the
EN/SC adapter.
Running
the
Loopback
test
The
Loopback verifies
the
operation
of
major
components
of
the
interface circuitry,
the
adapter,
the
serial
network
interface,
and
the
thin
port
transceiver
by
transmitting and receiving special packets.
If
you
have
an
adapter
with
BNC
connectors, disconnect
the
net-
work
cable
and
attach
the
T-connector terminating
both
ends
with
a
50
ohm
terminator.
To
run
the
Loopback test,
perform
the
following steps:
1 Click
the
Loopback Test
checkbox
to
select
the
test.
2 Click TEST
to
start
the
loopback test.
3
If
the
first
test
fails, click
REPEAT.
If
the
tests are "passed"
successfully, everything is operating properly.
If
you
leave
your
computer
connected
to
the
network
during
the
Loopback test,
the
test
may fail
due
to
packet
collisions.
The
test fail-
ure
does
not
indicate
that
the
equipment
is faulty. Retry
the
test
by
clicking REPEAT. You
need
only
one
successful
run
to
verify
proper
product
operation.
If
the
Loopback
test
fails repeatedly, please call Technical Support.
