FUNCTION MOD S:
The device has got two functions mode depending of the position of the ‘Dip1 of Dip-Switch A’:
The first, with ‘Dip1 of Dip-Switch A’ at “OFF” position, is used for the normal working of the device;
The second, with ‘Dip1 of Dip-Switch A’ at “ON” position, is used for uploading the Project and/or Firmware.
For the operations to follow for the updating, see ‘UPDATE DEVICE’ section.
According to the functioning mode, the LEDs will have specifics functions, see ‘LEDS’ section.

TH RN T:
The Ethernet connection must be made using Connector3 of HD67931-B with at least a Category 5E cable. The maximum length of the
cable should not exceed 100m. The cable has to conform to the T568 norms relative to connections in cat.5 up to 100 Mbps. To connect the
device to an Hub/Switch is recommended the use of a straight cable, to connect the device to a PC/PLC/other is recommended the use of a
cross cable.
M-BUS:
The M-Bus is a unpolarized bus.
A two wire standard telephone cable (JYStY N* *0.8 mm) is used as the transmission medium for the M-Bus. The maximum distance
between a slave and the repeater is 350m; this length corresponds to a cable resistance of up 9Ω. This distance applies for the standard
configuration having Baud rates between 300 and 9600 Baud, and a maximum of 50 slaves. The maximum distance can be increased by
limiting the Baud rate and using fewer slaves, but the bus voltage in the space state must at no point in a segment fall below 1 V, because
of the remote powering of the slaves. In the standard configuration the total cable length should not exceed 1000m, in order to meet the
requirement of a maximum cable capacitance of 180nF. (Taken from M Bus specifics)

M-BUS WIR L SS:
The standards of M-Bus Wireless are specified in EN 13757-4. The signal is @ 169 MHz or
433 MHz or 868 MHz (in relation to the order code).
The Antenna connector is a SMA Female (‘Female Outer Shell’ and ‘Female Receptacle’) so
the Antenna must have a SMA Male connector.
LT :
The Antenna connector is a SMA Female (‘Female Outer Shell’ and ‘Female Receptacle’) so
the Antenna must have a SMA Male connector.
The SIM type is Micro-Sim.

US OF COMPOSITOR SW67931:
To configure the Converter, use the available software that runs with Windows called SW67931. It is downloadable on the site
www.adfweb.com and its operation is described in this document. The software works with MS Windows (XP, Vista, Seven, 8, 10, 11;
3 /64bit).
When launching the SW67931, the window below appears (Fig. ).
Note:
It is necessary to have installed .Net Framework 4.

N W CONFIGURATION / OP N CONFIGURATION:
The “New Configuration” button creates the folder which contains the entire device’s configuration.
A device’s configuration can also be imported or exported:
To clone the configurations of a Programmable “M-Bus / M-Bus Wireless / MQTT -
Converter” in order to configure another device in the same manner, it is necessary to
maintain the folder and all its contents;
To clone a project in order to obtain a different version of the project, it is sufficient to
duplicate the project folder with another name and open the new folder with the
button “Open Configuration”.

SOFTWAR OPTIONS:
By pressing the “Settings” ( ) button there is the possibility to change the language of the software and check the updatings for the
compositor.
In the section “Language” it is possible to change the language of the
software.
In the section “Connection Options”, it is possible to check if there are some
updatings of the software compositor in ADFweb.com website.
Checking the option “Check Software Update at Start of Program”, the

This section is used to define the working mode of MQTT side of the converter. It is
possible to define:
Standard Mode: on MQTT side, the data inside the payload of the messages
are already readable and coded in relation to the user definition.
Raw Mode: on MQTT side, it is possible to see the M-Bus responses in raw,
without any decoding.
M-B US :
This section is used to define the main parameters of M-Bus line. The means of the
fields are:
In the field “M-Bus on Wire” it is possible to define if the port is present or
not;
In the field “Baudrate” the data rate of the M-Bus line is defined;
In the field “Parity” the parity of the M-Bus line is defined;
If the field “Cyclic Delay” the delay (expressed in seconds) between two M-
Bus scanning is defined;
In the field “Node State value when slave device is not present” it is
possible to insert the value to assign to the “Node State” when the Gateway
doesn’t find the interrogated M-Bus slave;
If the field “M-Bus request only when MQTT is connected” is checked, the
converter reads M-Bus side only if MQTT is connected.
