Description
The gateway is an interface that provides communication among different BUS systems.
The interface has two BUS clamps, IN and OUT. On the front is a C key for virtual configu-
ration and a LED for the notification of:
- correct power supply and configuration (ON steady)
- BUS not detected (OFF)
- configuration not detected or incorrect configuration (flashing).
The device may operate in six different modes:
- Physical expansion: can increase the total BUS length or exceed the current draw limit
of 1200 mA for the individual power supply unit.
- Logical expansion: can increase the number of devices of a system, which is 175 (max 11
in rooms defined with A = 0 to 10 and 16 light points with PL = 0 to 15).
Address A = 0, PL = 0 is not permitted.
- Burglar alarm/automation interface: it allows communication between these two sys-
tems.
- Public riser: it provides alarm event supervision for the common parts of the video door
entry system.
- Galvanic separation: can interface two different functions (eg: Sound System with Au-
tomation).
- Physical separation: brings together the features of the Physical expansion mode and
the Galvanic separation mode. It can be used for systems with devices preset for virtual
configuration.
NOTE: Regardless of the interface mode of use, it must be taken into account that
the two Buses connected constitute at all effects two systems, and, as such, they
must be subjected to all existing sizing and installation rules.
Technical data
Power supply via SCS BUS: 27 Vdc
Operating power supply with SCS BUS: 18 – 27 Vdc
IN clamp current draw: 25 mA
OUT clamp current draw: 5 mA
Dissipated power with max. load: 1 W
Dimensions
Size: 2 DIN modules
With the interface configured in this mode, it will be possible to extend the physical limit
of the maximum length of the BUS, or exceed the limit of 1200 mA delivered by the indi-
vidual power supply, but not the maximum number of actuators (max. 175).The positions
identified with I1 and I2 must not be configured. The “separation address” between the
two buses connected to the interface must instead be defined in positions I3 and I4. Sup-
posing as in the example that I3=3, I4=2:
- On the input BUS (IN) the addresses must go from A=0 / PL=1 and A=3 / PL=1;
- On the output BUS (OUT) the addresses must be between A=3 / PL=3 and A=9 /PL=9 or
the address of the next interface. As it can be seen from the example, all the automation
BUS 1 addresses are lower than that of the interface, while all the automation BUS 2
addresses are higher; the interface address therefore separates all the addresses of which
the complete system might be made up of into two or more blocks.

Installation example
Installation rules:
- Configure both I3 and I4 with configurators from 1 to 9, to set the separation between
the two Buses.
- I1 and I2 must not be configured.
- If several interfaces are installed in series, the addresses of the devices between one in-
terface and the other must be within those of the two interfaces (see system example).
- In this mode, it is not possible to install two interfaces in parallel on the same BUS.
- It is possible to install up to four interfaces in series, which subdivide the system in 5
separate sections, individually powered.
- The scenario module, the memory module, the IR emitter for the control of air con-
ditioning units, and the devices that can be configured in self-learning mode, must
be installed on the BUS section corresponding to the own local address (e.g. if the
scenario module is configured as A=0/PL=1, it will have to be placed on system
no. 1 - see system example).
-The web server and the scenario programmer must be installed on the BUS line with the
lowest addresses (system 1on the drawing).
- All control devices configured for sending Point-Point, Room, Group, and General con-
trols may be connected to any branch of the system (no.1 or no. 2), without limitation,
irrespective of their respective addresses in the A and PL positions.
- The above also applies to actuators configured in“slave”operating mode.
- Interface F422 allows Point-Point, Group, Room, and General controls to travel through
the various systems. It is therefore possible to install, for example, in system no. 2 a
control configured as A=1 and PL=5 that will control actuator A=1 and PL=5 installed
in system no. 1.
-Within the system, no device must be configured with the same address as the interface.

Installation example
This mode enables separation of control systems, with each of them therefore capable
of using all the addresses available. It is therefore possible to connect several systems to
an automation BUS, with each system having all the 175 addresses available.The BUS to
which all others are connected therefore operates as main riser.This BUS must necessari-
ly belong to an automation system. It is recommended that this mode is used for systems
installed in large villas or in the service/industrial sector.
A typical example may be a large villa on several floors: A system may be installed for
each floor, all connected to each other through another system operating as a riser. The
positions identified with l1, l2 and l3 must not be configured, while in the l4 position,
the address of the interface (l4 from 1 to 9) connected to the riser must be configured.
2) “Logic expansion”operating mode - configurator MOD = 2
Installation rules:
- Configure I4 with configurators from 1 to 9 to number the Buses connected to the riser.
- I1, I2 and I3 must not be configured.
- The BUS of the individual system connected to the main riser must be connected to the
OUT clamp of the interface.
- The main riser must consist of an Automation system in which, in addition to the cor-
responding control devices and actuators, it will also be possible to install the Energy
management central unit, temperature central unit, and the MH200N scenario pro-
grammer.
- In this mode up to nine interfaces may be connected to the main riser; it is possible to
manage up to ten systems as if they were a single one. Each system connected to the
riser can have all 81 addresses allowed.
- The web server and the scenario programmer must be installed on the BUS line with
the lowest addresses (system 1on the drawing).
- From the main riser (IN clamp), arrive the general controls (rolling shutters and lights),
group controls (this allows a minimum centralisation of the controls, using standard
devices of the control system), and power management controls (to allow positioning
of the power management central unit on the riser). On the other hand, point-point
controls are stopped by the interface, and therefore remain inside the individual sys-
tem, including the riser. The controls of all systems other than automation, including
AUXILIARY controls, travel in the two directions without any processing. In order to
send controls from one system to the other, the special controls H4651M2, L4651M2,
AM5831M2 and 067553 may be used in extended control mode.
- The interface address cannot be the same as that of other devices (e.g. configure the
interface l1= -, 12= -, 13= -, l4=1 and MOD = 2, if a scenario module is configured
with A = - and PL = 1).
Note (*): maximum number of addresses available with physical configuration. Maximum 175 addresses may be managed with virtual configuration.

Automation
This mode can be used to interface the Automation system to the burglar alarm system,
to facilitate interaction and exchange of information between the two BUS. Thanks to
this function, it is possible to remotely control the automation system using the tele-
phone communicator. The positions identified with l1, l2 and l3 must not be configured,
while in the l4 position, the address of the interface (l4 from 1 to 9) must be configured.
4)“Interface between burglar alarm and automation/video door entry system/
sound system”mode - configurator MOD = 4 -
Installation example
Burglar alarm
Automation
Video door entry system
Sound system
Installation rules:
- Configure l4 with configurators from 1 to 9.
- I1, I2 and I3 must not be configured.
- The BUS of the Burglar Alarm system must be connected to the OUT clamp of the in-
terface.
- It is not possible to connect other interfaces to the Burglar Alarm system, to physically
extend the BUS, or to increase the maximum number of devices.
- Only one interface may be connected to the Burglar Alarm system. It is therefore not
possible to connect together two Automation systems through the Burglar Alarm sys-
tem.
- Installation of the Automation system actuators within the Burglar Alarm system is
not allowed.
- The interface does not use any addresses of the Automation system.
This configuration enables keeping the power supplies of the two buses separate, allow-
ing interfacing of different My Home functions (e.g. sound system and automation). In
some cases, the use of this interface is necessary (for example when the sound system
is installed). In other cases installation alternatives are possible; for example, it will be
possible (but not compulsory) to install Temperature Control on a separate BUS, and in-
terface it with Automation using an interface in Galvanic Separation mode.
The positions identified with l1, l2 and l3 must not be configured, while in the l4 position,
the address of the interface (l4 from 1 to 9) must be configured.
5)“Galvanic separation”operating mode
configurator MOD = no configuration
Installation rules:
- Configure l4 with configurators from 1 to 9.
- I1, I2 and I3 must not be configured.
- The Automation BUS must be connected to the IN clamp. The other systems must be
connected to the OUT clamp (e.g. Sound System).
- It is not possible to connect several Automation systems to the same Sound System.
- Thanks to this mode, using the Web Server A/V it is possible to control a one-family
system (a video door entry system and an Automation system, at the most subdivided
into lines, following the physical and/or logic expansion mode procedure).
- The interface does not use any addresses of the Automation system.

This mode brings together the features of the “physical expansion”mode and the “gal-
vanic separation”mode.
Each system may be connected to both the OUT and the IN clamps of the interface and,
differently from what is required for“physical expansion” MOD=1, the addresses of the
devices of the two systems may be selected freely.
In view of the above, it will no longer be necessary to indicate the system separation
address in positions I3 and I4; therefore, the interface will have to be configured by as-
signing any address from 01 to 99, including any address already used by actuator de-
vices installed in the connected systems. If several interfaces are used, these must have
different addresses.

Installation rules:
- Each individual system connected to the IN or OUT clamps of the interface must be powered
by its own power supply.
- It is possible to use up to 4 interfaces in MOD=6 for the connection of the Automation and/
or Energy Management, and Temperature Control systems to each other.
- In case of cascade connection of several Automation and/or Energy management, and
Temperature Control systems, each individual system must be connected to the OUT clamp
of one interface and the IN clamp of the other. Therefore, do no connect the system to the
two interfaces only using the OUT clamps.
- Do not configure positions l1 and l2.
- In positions l3 and l4, address l3=0 to 9 and l4=1 to 9 of the interface must be specified.
This address may also correspond to that of other actuator devices installed in the connected
systems. If several interfaces are installed, these must have different addresses.
- The interface does not use any addresses of the Automation system.
- The scenario module and the devices that can be configured in self-learning mode can
be connected to any branch of the system (no. 1 or no.2). The memory module must be
connected to the system connected to the OUT clamp of the last interface.
- All control devices configured for sending Point-Point, Room, Group, and General controls
may be connected to any branch of the system (no.1 or no. 2), without limitation,
irrespective of their respective addresses in the A and PL positions.
- The above also applies to actuators configured in “slave”operating mode.
- Interface F422 allows Point-Point, Group, Room, and General controls to travel through the
various systems. It is therefore possible to install, for example, in system no. 2 a control
configured as A=1 and PL=5 that will control actuator A=1 and PL=5 installed in system
no. 1.
The use of the interface with this mode may be useful to keep the Automation system
and the Temperature control system separate (for example when using independent
power supplies).

Configuration:
For correct operation, the interface must be configured to:
- define its address within the system;
- acquire the address of the devices of the systems connected to the IN and OUT clamps.
Configuration of the interface address:
The device may be configured in 3 different modes:
- using numerical configurators, 0 to 9, in positions I3 and I4;
- using the Virtual Configurator application as indicated in the software User Manual;
- using the“self-configuration”procedure as indicated below:
1. press the interface pushbutton for a few instants; the LED flashes slowly.
2. press the pushbutton again; the LED flashes quickly and the device starts the self-
configuration procedure.
3. Once the configuration procedure has been completed correctly, the LED comes on steady.
Repeat this operation for all the interfaces in MOD-6 of the system.
Acquisition of the addresses of the connected devices:
This procedure must only be carried out after the configuration of the interface address (or
several interfaces, as applicable). It is possible to select one of two modes:
- using the Virtual Configurator application as indicated in the software User Manual;
- pressing the interface pushbutton for at least 2 seconds. Any other interfaces in MOD=6
installed in the system will automatically acquire the configuration of the devices.
Before performing this operation check that all system interfaces and actuators have their
addresses configured.

For home automation systems of a certain complexity, several systems may be integrat-
ed with interfaces configured in different modes. For example, it is possible to create
a system with three interfaces for the connection of two Automation systems and one
Burglar alarm system to one single riser.
If necessary, each of these can be expanded (physical expansion mode) or interfaced
with the Video Door Entry System or the Sound System using other interfaces. For exam-
ple, in case of a villa consisting of several large floors.
