3. Data converter installation precautions
a. Don’t install it in the place where flammable gas leaks easily.Once flammable gas
leakage occurs and stagnate around the device, it may result in fire.
b. Keep the device from heating element as far as possible.
c. Don’t install it in the place that is too dirty or humid.
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.
