Data
+
pulse
outputs
(Type
no.:
HC
‐
003
‐
11)
The
module
has
a
galvanically
separated
data
port
which
interoperates
with
the
KMP
protocol
(see
paragraph
12).
The
data
output
can
be
used
for
e.g.
connection
of
external
communication
units
or
other
hard
‐
wired
data
communication
which
it
is
not
expedient
to
carry
out
via
optical
communication
on
the
meter’s
front.
The
data
connection
is
galvanically
isolated
with
optocouplers,
which
makes
it
necessary
to
use
data
cable
type
6699
‐
102
in
order
to
adapt
the
signal
to
RS232
level,
which
is
suitable
for
PCs
and
other
RS
‐
232
‐
based
equipment.
See
paragraph
12.
Data Communication
for
information
on
data
sequences
and
protocols.
If
the
computer
does
not
have
a
COM
‐
port,
data
cable
with
USB
type
6699
‐
099
is
used.
If
data
cable
with
USB
is
used,
a
USB
driver
must
be
installed
on
computers
with
Windows
operating
system.
The
driver
can
be
downloaded
from

M
‐
Bus
+
pulse
inputs
(type
no.:
HC
‐

‐

The
M
‐
Bus
module
is
powered
through
the
M
‐
Bus
network
and
is
thus
independent
of
the
meter’s
internal
supply.
Two
‐
way
communication
between
M
‐
Bus
and
energy
meter
is
carried
out
via
a
digital
isolator
providing
galvanic
separation
between
M
‐
Bus
and
meter.
The
module
supports
both
primary,
secondary
and
enhanced
secondary
addressing.
The
module
can
communicate
at
communication
speeds
of
300,
2400,
9600
or
19200
baud
and
automatically
detects
the
speed
used.
The
output
data
package
can
be
configured
to
include
various
register
combinations
by
means
of
the
PC
‐
programs
METERTOOL
HCW
and
READy
Manager.
The
module
is
fitted
with
two
sets
of
screw
terminals
for
connection
to
the
M
‐
Bus
network.
Hence
the
M
‐
Bus
cable
can
be
looped
through
the
meter
and
the
use
of
connection
boxes
be
avoided.
The
connection
is
independent
of
polarity.
The
M
‐
Bus
cable
must
be
a
copper
twisted
pair.
Maximum
cable
size
is
1.5
mm².
