The communication protocol and the relevant software are available at www.algodue.com
WARNING! Device installation and use must be carried out only by qualified professional staff. Switch off the voltage before device installation.

CABLE STRIPPING LENGTH

For the module terminal connection, cable stripping length must be 5 mm. Use a blade screwdriver with 0.8×3.5 mm size, fastening torque 0.5 Nm. Refer to picture B.

CONNECTIONS

A master interface is required between PC and the M-Bus network to adapt RS232/USB port to network. The maximum number of modules to be connected can change according to the used master interface. For the connection among the different modules, use a cable with a twisted pair and a third wire. After making M-Bus connections, combine each M-Bus module with a single meter: place them side by side, perfectly lined up, with module optical port facing the meter optical port. Refer to picture D.

LEDS FUNCTIONALITY

Two LEDs are available on the module front panel to provide power supply and communication status:

M-BUS MASTER APPLICATION

M-Bus Master is an application software which allows to manage M-Bus module communication. With this application software it is possible to:

detect and communicate with M-Bus modules
change M-Bus module settings
display the detected measurements of the energy meter connected to the M-Bus module
set the measurement rate and type to be detected

To use M-Bus Master, follow the instructions:

Connect one or more modules on M-Bus network as previously described.
Place one counter for each M-Bus module: module optical port must face up to meter optical port.
Install M-Bus Master on PC.
At the end of installation, run M-Bus Master.
Carry out a search for the available M-Bus modules on the network.

SET DEFAULT FUNCTION

SET DEFAULT function allows to restore on the module default settings (e.g. in case of M-Bus primary address forgotten). To restore default settings, keep SET DEFAULT key pressed for at least 5 s, communication LED will blink green/red for 5 s. At the end of SET DEFAULT procedure, communication LED will be red continuously indicating to release the key.
Default settings:
M-Bus primary address = 000
M-Bus secondary address (ID number) = Progressive value on 8 digits
M-Bus communication speed = 2400 bps
Mask of data detected on the meter by the module = Default
