4.3. Gateway General Funconality
With this Intesis IN770AIR00xO000 gateway, you can easily integrate Mitsubishi Electric City Mul systems into
an installaon based on Modbus TCP, Modbus RTU, KNX, BACnet/IP, BACnet MS/TP, or Home Automaon. To do
so, the gateway acts as a server device of the installaon itself, accessing all signals from each air condioner unit
and controlling the whole AC network.
The gateway is connuously polling the AC network, storing in its memory the current status of every signal
you want to track and serving this data to the installaon when requested. Also, when a signal status changes,
the gateway sends a write telegram to the installaon, waits for the response, and performs the corresponding
acon.
A lack of response from a signal acvates a communicaon error, allowing you to know which signal from which
AC unit is not correctly working.

5. Hardware
5.1. About Mitsubishi Electric Centralized Controller for M-Net
This integraon requires the Mitsubishi Electric City Mul AC system to be equipped with a Mitsubishi Electric
Centralized Controller for M-Net. This Centralized Controller oers the signals of the City Mul AC system
through XML protocol to its Ethernet port, which is accessed by the Intesis IN770AIR00xO000 gateway.
IMPORTANT
Most Mitsubishi Electric Centralized Controllers require a PC-Monitoring (SW-Mon) soware license,
which must be purchased together with the centralized controller for the XML interface to be acve
and used by the Intesis gateway.
IMPORTANT
List of compable centralized controllers:
• G-50
• G-50A
• GB-50A
• GB-50ADA
• AB-150
• AE-200

• AG-150A
• EW-50
• EB-50GU
5.2. Mounng
IMPORTANT
Before mounng, please ensure that the chosen installaon place preserves the gateway from direct
solar radiaon, water, high relave humidity, or dust.
IMPORTANT
Maximum mounng height: below 2 meters (6.5 feet).
NOTE
Mount the gateway on a wall or over a DIN rail. We recommend the DIN rail mounng opon,
preferably inside a grounded metallic industrial cabinet.
IMPORTANT
Ensure the gateway has sucient clearances for all connecons when mounted. See Dimensions
(page 20).

IMPORTANT
• Use SELV-rated NEC class 2 or limited power source (LPS) power supply.
• Respect the polarity.
• Connect the gateway's ground terminal to the installaon grounding.
• A wrong connecon may cause earth loops and damage the Intesis gateway and/or other system

5.3.2. Connecon Procedure for the AC Unit
Connect the Mitsubishi Electric central control network to the gateway using the Ethernet Port.
IMPORTANT
Use an Ethernet CAT5 or higher cable.
IMPORTANT
If communicang through the LAN of the building, contact the network administrator and make sure
trac on the used port is allowed through all LAN paths.
NOTE
When commissioning the gateway for the rst me, DHCP will be enabled for 30 seconds. During
that me, if there is a DHCP server, an IP address will be automacally assigned to the gateway. If
there is no DHCP, you can type an IP address of your choice. Aer that me, the default IP address
192.168.100.246 will be automacally set.
NOTE
See the Wiring diagram (page 10).
5.3.3. Connecon Procedure for Modbus
For Modbus TCP:
Connect the Modbus TCP Ethernet cable to the gateway's Ethernet Port. The correct cable to use depends on
where the gateway is connected:
•Connecng directly to a Modbus TCP device: use a crossover Ethernet UTP/FTP CAT5 or higher cable.
•Connecng to a hub or switch of the LAN of the building: use a straight Ethernet UTP/FTP CAT5 or higher
cable.
NOTE
Some devices detect the dierence automacally and adjust themselves.
NOTE
When commissioning the gateway for the rst me, DHCP will be enabled for 30 seconds. During
that me, if there is a DHCP server, an IP address will be automacally assigned to the gateway. If
there is no DHCP, you can type an IP address of your choice. Aer that me, the default IP address
192.168.100.246 will be automacally set.

IMPORTANT
If communicang through the LAN of the building, contact the network administrator and make sure
trac on the used port is allowed through all LAN paths.
For Modbus RTU:
Connect the Modbus RTU communicaon cable to the gateway's EIA-485 port.
The connector for the EIA-485 bus is a green pluggable terminal block labeled SG (signal ground), B-, and A+.
IMPORTANT

Remember the characteriscs of the standard EIA-485 bus:
• Maximum distance of 1200 meters (0.75 miles).
• Maximum of 32 devices connected to the bus.
• A 120 ohms (Ω) terminaon resistor is needed at each end of the bus. The gateway has an internal
bus biasing circuit already incorporang the terminaon resistor. It can be enabled using the DIP
switch block (SW A) dedicated to the EIA-485 port:
Posion 1
– ON: 120 Ω terminaon acve.
– OFF: 120 Ω terminaon inacve.
Posions 2 and 3
– ON: Polarizaon acve.
– OFF: Polarizaon inacve.
For further details, see DIP Switches (page 17).
IMPORTANT
When installing the gateway at the end of the bus with the terminaon resistor enabled, do not
install an addional terminaon resistor at that end.
NOTE
See the Wiring diagram (page 10).
5.3.4. Connecon Procedure for KNX
Connect the KNX TP communicaon cable to the gateway's KNX port.
IMPORTANT
Observe polarity.
NOTE

USER MANUAL Version 1.0.8 Page 13 of 42

5.3.5. Connecon Procedure for BACnet
For BACnet/IP:
Connect the BACnet/IP Ethernet cable to the gateway's Ethernet Port. The correct cable to use depends on
where the gateway is connected:
•Connecng directly to a BACnet/IP device: use a crossover Ethernet UTP/FTP CAT5 or higher cable.
•Connecng to a hub or switch of the LAN of the building: use a straight Ethernet UTP/FTP CAT5 or higher
cable.
NOTE
Some devices detect the dierence automacally and adjust themselves.
NOTE
When commissioning the gateway for the rst me, DHCP will be enabled for 30 seconds. During
that me, if there is a DHCP server, an IP address will be automacally assigned to the gateway. If
there is no DHCP, you can type an IP address of your choice. Aer that me, the default IP address
192.168.100.246 will be automacally set.
IMPORTANT
If communicang through the LAN of the building, contact the network administrator and make sure
trac on the used port is allowed through all LAN paths.
For BACnet MS/TP:
Connect the BACnet MS/TP communicaon cable to the gateway's EIA-485 port.
The connector for the EIA-485 bus is a green pluggable terminal block labeled SG (signal ground), B-, and A+.
IMPORTANT
Observe polarity.

NOTE
See the Wiring diagram (page 10).
5.3.6. Connecon Procedure for Home Automaon
Connect the Home Automaon Ethernet cable to the gateway's Ethernet Port. The correct cable to use depends
on where the gateway is connected:
•Connecng directly to a Home Automaon device: use a crossover Ethernet UTP/FTP CAT5 or higher cable.
•Connecng to a hub or switch of the LAN of the building: use a straight Ethernet UTP/FTP CAT5 or higher
