MOUNTING
Use the included wall bracket for mounting the product on a suitable
indoor wall. For outdoor usage, a special enclosure is needed. When
mounting several CMi-Boxes with internal antenna, make sure to spread
them to get the best coverage throughout the property.
POWER SUPPLY
The installation should be performed by a qualified electrician or an
installer with the required knowledge. The power supply should be
connected via a clearly marked, easily accessible switch so the unit can
be switched off during service work.
Power supply 230 VAC
The 230 VAC supply is equipped with a 3 m cable for connection to main
power.
Power supply 24 VAC/VDC
Connect the external 24 V power supply to the push connector on
the Elvaco 24 VAC/VDC power supply (1). It is possible to use a cable
with four conductors. Two of the conductors will be used for 24 V
power supply, and two for M-Bus. The input for 24 VAC/VDC is polarity
independent.
ANTENNA
The product is available with external or internal antenna.
External antenna
Mount the antenna in a suitable place, if both GSM/GPRS and Wireless
M-Bus antennas are used, place the antennas at least 1.5 m apart from
each other. Connect the cable/cables to the SMA connector (6, 7).
If the antenna’s range is inadequate, please contact Elvaco for more
information about antenna options.
IMPORTANT
•
Do not mount the antenna close to any metallic objects.
•
Do not mount the antenna close to the M-Bus 2-wire bus.
•
Do not mount the antenna inside a metallic cabinet.
•
The SMA connector should be connected to the antenna when the
antenna wiring is done. Otherwise it can be damaged.
Internal antenna
There is no possibility to connect an external antenna to the version of
CMi-Box with internal antenna. If the internal antenna is inadequate,
please contact Elvaco for information.
M-BUS SLAVE PORT
The product is equipped with an M-Bus slave port to enable wide
integration. The port can be used to read the connected wireless M-Bus
slaves as normal M-Bus slaves.
Slaves can be read using primary and/or secondary addressing. The
CMi5110 inside the CMi-Box is available as an M-Bus slave with the
secondary address equal to its serial number.
The M-Bus 2-wire interface acts like any other M-Bus slave device on
the 2-wire bus. The nominal current is 1T (1.5 mA). This interface can be
directly used with any standard M-Bus master.
GETTING STARTED
If the CMi-Box is to deliver readings from wireless meters, its internal
M-Bus Master CMi5110 must first be installed. The intallation can be
performed in three different ways:
Option 1: Press button (12) to start the installation on CMi5110. When the
installation mode is started, the blue LED will light up. The CMi5110 will
constantly search for new meters to install.
Option 2: Start the installation by M-Bus commands, for example
by using Elvaco’s CMe3100. This allows for easy adjustments and
administration of parameters and meter lists.
Option 3 (for CMi2110 version): Use SMS commands to install and
configure the CMi-Box. Contact Elvaco for information about settings.
