4 Description of the M-Bus Display

Function
The M-Bus Display allows reading the meters using the keyboard and viewing the consumption
values on the LCD. The meter reader is then able to get the data of many meters from one
central location without the need to enter all the flats and without further technical equipment
(laptop). Additionally the device offers a so-called command mode for remote readout of meters
using a standard modem (10-bit). The M-Bus software DokomCS and FService support this
command mode.
Installation
After login with a passcode (predefined as 00001767) the operator gets access to the menu
system, which is described later. It is important to generate the list of meters for readout of data.
The automatic search for installed meters will be much faster, if the user reduces the search
options in search mode or search baudrates (e.g. searching with 300 baud is very slow). These
options can be selected in the menu „Display config." You should also change passcode B to
prevent other persons from changing the setup and passcodes.
Error messages
An exceed of the maximum allowed current and short circuit are signalled with LEDs under the
terminal lid compartment and also on the LCD. If there are problems with interpretation of the
M-Bus data the display shows „Status: Error". The "list of errors" is shown on the LCD after
simultaneously pressing the  and C keys in the inactive state. Please note the error codes and
then delete the error codes by pressing the  key. The most important error codes can be
decoded using the table in the addendum. On restart after power fail the error list is also deleted.
Passcode protection
The M-Bus Display distinguishes between 3 passcode modes and 2 passcode levels:
The operator is requested to enter a passcode after pressing any key in the standard mode
(mode A). In this mode the passcode A (reader´s passcode) gives only low level access
limited to readout functions. The caretaker or tenant can read single meters by selection from
the list of slaves or all meters from the network. It is not possible to change the list of slaves or
other options of the M-Bus Display here.
The login with the passcode B instead of passcode A gives access to the complete menu. On
delivery the predefined value for passcode A is 00000000 and for passcode B is 00001767.
This allows a simple login to level A by just pressing the E-key. We strongly recommend to
change passcode B to avoid manipulation by unauthorized persons. You can setup the
passcode from the menus „Display config. – New passcode A" and "Display config. – New
passcode B".
