4-3. FE-1 SELF DIAGNOSTIC SOFTWARE
The
identification
of
errors
within
the
FE-1
chassis
is
triggered
in
one
of
two
ways
:-
1:
Busy
or
2:
Device
failure
to
respond
to
IIC.
In
the
event
of
one
of
these
situations
arising
the
software
will
first
try
to
release
the
bus
if
busy
(Failure
to
do
so
will
report
with
continuous
flashing
LED)
and
then
communicate
with
each
device
in
turn
to
establish
if
a
device
is
faulty.
If
a
device
is
found
to
be
faulty
the
relevant
device
number
will
be
dis-
played
through
the
LED
(Series
of
flashes
which
must
be
counted)
See
Table

non
