3.4.4. ID Function
When TCP232-302 works as TCP Client, it can send ID when establish a connection or carry ID when
sending data.TCP232-302 ID is decimal .1-65535
( ID function and transparent transmission can’t work at same time )
3.4.5. Index Function
When TCP232-302 works as TCP Server, it can establish 16 links simultaneously at most. Default is 4 .
Take 4 link as example, Server send data to 4 Client simultaneously or Server can’t distinguish the data
source, Index can realize the choice of data source of sending or receiving.
Index function can be set by software or web-page.
3.4.6. RFC2217 Function
By this function , TCP232-302 port parameter can be modified when working . E.g. change baud rate
from 115200bps to 9600bps. The function can be set by software or webpage. By default , it is checked.
When RFC2217 function of TCP232-302 is checked, RFC2217 function of USR-VCOM software is also
checked, the baud rate of software on PC will automatically matched with the baud rate of TCP232-302.
3.5. Additional Function
3.5.1. Display IP and Data
On the webpage of TCP232-302, it can display the IP of device and sent/received data byte, and the total
data byte of TCP232-302.
In TCP Mode, it can display the TOP 5 device IP and sent/received data byte. In UDP Mode, it only
display sent/received data byte.
3.5.2. Serial Port Parameter Setting

pin and specific baud rate.
3.5.3. Set Client Number in TCP Server Mode
In TCP Server Mode, The maximum number can be configured by user. TCP Client number is from 1
to 16, default value 4. When the Client link is more than 16, the new link will replace the former link from Link 1
When the Client link is more than 4, send and receive data at same time , the data flow should be within
2.5 KB/s
3.5.4. Defined MAC Address
Mac address can be modified. Factory Mac address is exclusive.
3.5.5. Defined DNS Server IP
To resolve server domain name, user should send data by gateway or router, then gateway or router
Distributes IP address, it can show IP in the webpage. User can set specific domain name resolution IP,
