1.6 Error Responses
A third-party device serves as the master Modbus device while SDV5-MOD serves as the
slave device.
The master device sends a request and waits for a response from the slave device. When no error
occurs, the slave device responds normally. If a data check error occurs, the slave device does
not respond. When data sent by the master device have an error other than the data check error,
the slave device responds with an error.
Meaning
The slave device receives a function
code that cannot be executed.
The received data address is not supported by the
slave device.

2. Using the Product
2.1 Configuring the PC IP Address
The default IP address of the SDV5-MOD is 192.168.1.185. The PC used for accessing the
Web page of SDV5-MOD must be in the same network segment as SDV5-MOD.
Open the "Internet Protocol Version 4 (TCP/IPv4) Properties" dialogue box and set the IP address
and subnet mask, for example, set the IP address to 192.168.1.10 and the subnet mask to
255.255.255.0.
After configuration, click "OK".
Note: The above configuration is for reference purposes only. Please follow instructions of IT
personnel during actual projects.

2.2 Configuring the Gateway
In the address bar of the browser (*Note 3), enter "http://192.168.1.185:8586". The Web page of
the SDV5-MOD is displayed, as shown in the figure below.
*Note 3: Internet Explorer (IE) is the recommended browser.
The table below describes the parameters.

2.3 Restoring Factory Settings
2.4 Checking Air Conditioner Information
Click the "DataView" tab on the Web page, and click "Discrete inputs" or "Holding registers" to
check information about air conditioners.
When "Discrete inputs" is selected, a page as shown in the figure below is displayed.
Press "SW1" three times consecutively within 5 seconds after SDV5-MOD is powered on, to
enable the device to enter the factory setting restoration mode. The RUN indicator blinks rapidly
at a frequency of 5 Hz. After factory settings are restored, the system automatically restarts, and
the RUN indicator blinks normally at a frequency of 1 Hz.
Click the address No. of an IDU or ODU. Operation information about the air conditioner is
displayed.
When "Holding registers" is selected, a page similar to the one shown in the figure below is
displayed.

3.2 Mapping Table Description — Input Registers
The specific functions of input registers depend on the models. For example, register address
30002 indicates the set temperature for heating when the IDU is an HTHM and indicates the fan
speed when the IDU is a non-HTHM VRF unit.
