MULTICAL

must
be
ordered
with
encrypted
data
transmission
between
module
and
reading
system.
Data
is
encrypted
with
128
bit
AES
counter
mode
encryption.
Data
transmission
can
be
encrypted
with
either
a
common
or
an
individual
encryption
key.
If
you
choose
individual
encryption
key
(T
‐
code
3)
the
reading
system
must
know
the
encryption
key
of
each
meter
in
order
to
read
the
meter.
The
encryption
key
is
sent
to
the
customer
and
then
”matched”
with
the
serial
number
of
the
individual
meter
in
the
reading
system.
If
you
choose
common
encryption
key
(T
‐
code
2)
the
key
can
be
used
for
reading
a
customer
specific
number
of
meters.
The
key
is
created
by
Kamstrup
A/S.
A
customer
can
have
several
encryption
keys,
e.g.
one
for
each
meter
type.
Note:
The
common
encryption
key
is
only
offered
to
customers
on
request.
The
encryption
level
is
configured
as
part
of
the
meter’s
configuration
number
via
the
T
‐
code.
Upon
receipt
of
order
the
T
‐
code
is
by
default
configured
at
3
‐
individual
encryption
key
(unless
otherwise
informed
by
the
customer).
The
encryption
level
can
be
configured
when
submitting
the
order.
The
encryption
level
cannot
be
changed
after
delivery.
