4. SYSTEM INTRODUCTION
M-INTERFACE is a Central Air-conditioning multi-connected devices’ gateway which based on WEB,
is an important part of Intelligent Manager system (IMM). Connect to Central Air-conditioning devices
through the M-net terminal. It can connect the multi-connected devices through its M-net connector
(M-net connector is XYE communication terminals and K1K2E communication terminals); under the
auto topology mode, it can connect 4 refrigerant systems at most (can insert 256 sets indoor units and
16 sets outdoor units); under the manual topology mode, it can connect16 refrigerant systems at most
(can insert 256 sets indoor units and 64 sets outdoor units). The operation methods of auto topology
and manual topology please refer to IMM TECHNOLOGY MANUAL. The appearance interface of
M-INTERFACE gateway as follow displays:

4.1 M-INTERFACE Network
1) M-INTERFACE gateway can connect the local area network or Internet network through LAN
terminal. M-INTERFACE network topology as follows Fig 4-1.
2) M-net terminals are listed to be two rows, 1-4 are XYE terminals, 5-8 are K1K2E terminals.
Computer or other similar devices can visit M-INTERFACE WEB through browser, and then local
or remote control the devices.
4.2 Models which could be inserted
1) Can freely insert all VRF models.
2) If mini VRF will be connected to the project and need power consumption function, the outdoor unit
must be connected to an extra module.
3）Details refer to IMM TECHNOLOGY MANUAL.
4.3 Base on WEB technology
M-INTERFACE is a gateway based on WEB technology, unrelated to computer or similar devices
operation systems. M-INTERFACE insert into network then can browse the WEB page through the
browser of system platform, we suggest using IE (9.0 or above), Firefox (11.0 or above), Chrome (18.0
or above) or Safari (5.1 or above).
4.4 Local network connection
M-INTERFACE gateway can connect to the LAN network through switch. IP address of computer or
similar devices must in the same subnet area as the IP address of M-INTERFACE gateway.
Fig.4-1
Page 11
Installation & Owner's Manual
10
4.4.1 IP conguration
Default IP of gateway is 192.168.100.40, subnet cover code is 255.255.255.0. IP address of computer or similar devices should manual configure the statistic IP and within the range of 192.168.100,
subnet cover code should be 255.255.255.0. If the computer only insert the M-INTERFACE network,
then use the way of configuring single IP; if the computer also inserts the local network beside
M-INTERFACE network, then use the way of conguring several IP. Methods as follow (Take windows
7 system for example).
1) Congure single IP
Open the property dialogue box to congure the IP address and subnet cover code, for example: IP:
192.168.100.44, subnet cover code: 255.255.255.0.
After conguration, click the “OK” button.
2）Congure several IP
Before congure several IP, it needs to congure a statistic IP address, conguring steps as follow:
■ Check the local IP
Open the property dialogue box, as Fig.4-2 display, if the option “Use the following IP
addresses(S)” has been selected, and the interface displayed IP address, that means the local
IP is statistic IP address. Otherwise it is a dynamic IP address, then it needs to configure a
statistic IP address.
■ Congure statistic IP address
Open the “Start” menu, and type “cmd” in the search column, and display the dialogue box as
follow:
Fig.4-2
Page 12
Installation & Owner's Manual
11
Fig.4-3
Type “ipcong” in the above gure, then the interface will display the local dynamic IP address, and it
will write this IP address into the property dialogue box, and nish the statistic IP address conguration,
details please consult the local network administrator.
After the statistic IP address configuration, open the property dialogue box again, select the
“Advanced”, and display the TCP/IP setting dialogue box as follow:
Fig.4-4
Click the “ADD” button under IP address column, and add a IP address with the same network
segment of “192.168.100.40”, such as IP: 192.168.100.101, sub network cover code: 255.255.255.0,
and click “OK” button.
Page 13
Installation & Owner's Manual

4.4.2 Local LAN access
If there is a computer or other similar device of same subnet area as M-INTERFACE in LAN, then
type the link address of M-INTERFACE gateway (e.g.: http://192.168.100.40) on the browser address
bar can visit the M-INTERFACE WEB interface to operate the air-conditioning device. The local visit
topology structure as follow display:
Fig.4-5
4.5 Remote network connection
Under the allowable situation, M-INTERFACE gateway can set in the ofce network; the user can
operate the air-conditioning device through the computer or similar devices. Remote insert should base
on some IT technology and help by the network administrator. Three remote insert methods:
1) Statistic IP
Configure public network address statistic IP address for M-INTERFACE gateway, and set it in
the internet; directly visit this public network address then can visit the WEB interface. Ask the local
network operator for the public network address. The public network address insert fee will be charged
by opera-tor, and consider the network safety at the same time.
Fig.4-6
Page 14
Installation & Owner's Manual

Fig.4-9
2) Network terminal mapping
If the company has a public network address, then it needs to send a mapping of a terminal in re
wall to M-INTERFACE gateway; when the computer or similar device of outside network visit the
M-INTERFACE, then take http:// public network IP: visit as a terminal. E.g.: http:// 203.208.60.72:6080.
3) VPN visit
■ Router establishing
M-INTERFACE gateway might use a same public IP address with other devices, under the
situation of network cannot send terminal mapping to M-INTERFACE gateway, and then can use
VPN for visiting. As the gure displayed, VPN tunnels establish between routers, and then can
visit WEB interface through VPN tunnels. VPN Server can be established by oneself also can be
rented. Its topology structure as follow display:
■ Computer establishing way
Establish VPN tunnel by computer is a little difficult for general users. Use VPN client-side
software and VPN Server to establish VPN tunnel in the user’s computer, then user can visit WEB
interface through VPN tunnel. VPN client-side software and VPN Server can be achieved by
commercial ways. Its topology structure as follow display:

2) Wrong password
When the password was wrong, it would display as follow:
Type the correct password again.
7.3 No device displayed
If login successfully, and no data display in the home page, then contact the dealer or technicians
to check whether the wiring of M-net communication terminal was correct, and whether the air-
conditioner system has been insert correctly to the M-INTERFACE gateway.
7.4 Control operation failed
When changing the operating status of the indoor unit, there might be prompt message of “Setting
failed”, which means the current operation failed. Contact the dealer or technicians to check whether
the communication between the device and M-net terminal was correct, and also the Ethernet.
7.5 No respond in page
When operating the page and no respond or display “No connection” message, that means the
network communication between computer and M-INTERFACE gateway was broke off, and it needs to
