M-INTERFACE gateway controller is used for query and controls the air-conditioning indoor unit,
and transmits the status information of indoor unit to the computer and transmits the controlling and
querying orders sent by the computer to the indoor unit.
1) M-INTERFACE gateway controller indication instructions
M-INTERFACE gateway has 8 M-net terminals, 1 LAN terminal, 8 M-net terminal indication lamps, 4
status display lamps (Power, Status, Alarm, and Modem) and power switch. Connect to the central air-
conditioning system through the M-net terminal, and connect the local area network or Internet network
through LAN terminal. Computer or other similar devices can visit M-INTERFACE WEB through
Brower, and then local or remote control the devices.
■ Install the gateway at a side of M-net communicating bus, do not install it in the middle of the
bus.
■ Use 3-core shielding wire with 0.7mm2~1.0mm2 for wiring, details please refers to professionals.

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:
