General
The M-Bus Interface Module XC is designed for use with the EMH LZQJ-XC and DMTZ-XC
meters. The module is equipped with a M-Bus (passive) interface (M-Bus level converter /
transparent).
The module can be plugged easily into the module compartment of the meter. It can be mounted
or exchanged during operation (without breaking approval seal). Due the transparent mode, the
modules are suitable for all common control centres.
Compatible meters
LZQJ-XC (special meter for industrial applications):
- Standard meter for direct connection
- Transformer connection version Cl. B (Cl. 1)
- Precision meter Cl. C (Cl. 0.5S)
- Precision meter Cl. 0,2S
DMTZ-XC (residential meter)
Functions
The AMR interface contains the following functions:
Bi-directional communications: an integrated M-Bus
(2 wires, passive) interface provides a simple
means of connecting multi-energy meters. This
makes multi-energy applications an affordable
proposition for domestic use.
Alternative: BFC-Bus (BAER Field Control, 56VDC)
Transmission protocol: IEC 62056-21 or DLMS
Internal communication interface for the transfer
billing data and load profiles between the meter and
AMR module.
For details of the communications protocol, refer to
the software interface specification (IEC 62056-21
and OBIS Codes).
Transparent data readout (without protocol
conversion).
Internal power supply from meter.
Exchangeable during the meter operation.
Safety Notes
The owner of the modules is also responsible for:
• The protection of persons.
• The prevention of material damage.
• The training of personnel.
The following safety regulations must be observed at all times:
• Devices which have fallen down should not be installed, even if no damage is apparent, and should
be returned for testing to an authorised service centre (internal damage possible).
• Modules must never be cleaned with running water or high pressure devices. Water can cause
short-circuits or damage el. components.

Installation Hints
The installation must be done in a way, that even in the case of cable break no dangerous voltages
are applied to touchable parts of the module. Generally, meters are delivered with the communication
modules installed. The fitting of a meter with a communication module is, therefore, an exception and
can be necessary e.g. when a module needs to be replaced.
Strictly observe the safety regulations!
The interface module is exchangeable during the meter operation. Fit the interface module in the meter
as follows:
Installation of the interface module:
1. Check the interface module.
2. Remove the terminal cover [5].
3. Open the transparent cover [1].
4. Insert the interface module [3] carefully at the
place provided in the meter [2].
5. Push the module in to the internal contacts
6. Connect the cable.
7. Close the transparent cover [1].
8. Close the terminal cover [5].
Removing of the interface module:
9. Remove the terminal cover [5].
10. Open the transparent cover [1].
11. Disconnect the cable.
12. Remove the interface module.
13. Close the cover [1].
14. Close the terminal cover [5].
LED Displays
Two LED’s display the current operating status of the module and give information about the data transfer.
Tx:
on: communication via M-Bus interface: transmit data
Rx:

Communication
The interface port is conforming to IEC 62056-21 with fixed baud rate. For setting the baud rate use
please the EMH COMBI-TOOL-Software: menu Meter Interfaces Electrical interface.
For reading data the meter-ID (device address) can be used (e.g. /?<meter-ID>!).
Explanations of massage contents (see IEC 62056-21):
Start character: / (forward oblique, code 2F

Example for communication path:
Sign-on sequence: /?! CR LF without meter-ID
or /?12345678! CR LF if the meter-ID := 12345678
Answer: /EMHzIdent CR LF z := baud rate identification
