II. Installation and Operation of the Data Converter
1. System structure diagram
The system mainly includes the central air conditioning system, data converter, router, App,
cloud server, and Web client. The user can monitor the air conditioning system via App or
Web client. The data converter is connected to the XYE bus of the air conditioner via port 485
of the air conditioner. The power supply is connected to the mains supply via an adapter. For
the detailed connection, see the following figure:
3
NOTE
It is recommended to wire from the Outdoor XYE port
Fig.2.1 Schematic diagram of connecting the outdoor unit to the central air-conditioning
system.

If the data converter can only be connected to the outdoor unit, the outdoor unit shall be set
to enable automatic addressing so that the indoor unit can be located. For multiple systems,
port XYE of the outdoor unit is connected to the data converter in hand-in-hand manner. To
use one LAN cable to connect multiple CWC15 gateways, associate CWC15 gateways with
one router. For the configuration, see section 3.1.

4. LED Indicators
POWER: It is a power indicator, indicating that the power supply of the system is normal and
the system is running.
IP: It is a network communication indicator. When it flashes, it indicates that the data
converter is accessing the Ethernet. When it is off, it indicates that the data converter is not
accessing the Ethernet. In this case, check network connection and configuration.
485: It is an air conditioner communication indicator. When it flashes, it indicates that the
communication between the air conditioner and data converter is normal. When it is off, it
indicates that cable connection to port 485 is wrong or port 485 is not connected to an air
conditioner.
The data converter is restarted upon detecting abnormal communication. (If port 485 does not
communicate within 60s or the network port does not communicate within 3 minutes, the data
converter is reset.) In this case, POWER, IP, and 485 indicators are on together.
