2.2. System Architecture Description
It supports two kinds of outdoor unit with baud rates of 600 and 4800. (For detailed information, please contect our technical support). The
addresses of accessed indoor/outdoor units can’t repeat.
1) When the baud rate of the outdoor unit is 600, 64 indoor units and 4 outdoor units can connect to it at once.
2) When the baud rate of the outdoor unit is 4800, 60 indoor (with the address from 4—63) units and 4 outdoor units can connect to it at most.
The upper computer system with Modbus protocol access to terminal A2B2E by RTU or by TCP to connect to modbus gateway. See the connection
figure between modbus gateway and air-conditioner system below: Connection through Modbus TCP:
Note:XYE port and K1K2E port connect hand in hand,and then access to A1B1E port.

Function code Function name Function
0x01 Read Coils Read
0x04 Read Input Register Read
0x10 Write Holding Register Write
2.4. Abnormal Reply
The master unit sends requests and waits for reply from the slave.When there’s no error occurs, the slave will reply normally, but when there’s data
checking error, the slave won’t answer. When the master unit sends wrong data (except for checking error), the slave will answer abnormally.
Code Name Meaning
0x01 Illegal function code Function code received by the slave
can’t be executed.
0x02 Illegal data address The received data address is not
allowed.
0x03 Illegal data Value in query data field is not allowed
by the slave
0x06 Slave busy The slave is busy with a long-time
program command. Ask the master to
send messages when the slave is free.
3. Usage Introduction
3.1. IP Configuration
The default IP address is 192.168.1.200 when modbus gateway leaves the factory. The PC used for visiting websites must be in the same subnet
segment with modbus gateway, which means it should be 192.168.1.xx (xx is from 2 to 254). There are 2 ways to configure IP: static configuration
and multi-IP addition
1.1.1. Single IP Configuration
Open protocol dialog, configure the IP address and subnet mask, for example: IP: 192.168.1.211, subnet mask 255.255.255.0
Fig.3.1
After setting, click “OK” button.

Configure a static IP address before adding multiple IP.
Open protocol dialog and choose Advanced tab. TCP/IP setting dialog will display like below:
Fig.3.2
Click “Add” in IP address bar to add an IP address which is in the same segment as “192.168.1.200”, e.g., IP: 192.168.1.209 subnet mask
255.255.255.0 and click “OK”
Configuration
Input http://192.168.1.200 in the address bar in IE (suggest to use IE). Choose “Configuration” when web page of modbus gateway displays, as
shown below:
