Description 
Destination Host 
Set the IP address of host and the port number of data port. .  
Idle Timeout 
When serial port stops data transmission for a defined period of time 
(Idle Timeout), the connection will be closed and the port will be freed 
and try to connect with other hosts. 0 indicate disable this function. 
Factory default value is 0. If Multilink is configured, only the first host 
connection is effective for this setting.  
Alive Check 
The serial device will send TCP alive-check package in each defined time 
interval (Alive Check) to remote host to check the TCP connection. If the 
TCP connection is not alive, the connection will be closed and the port 
will be freed. 0 indicate disable this function. Factory default is 0.  
Connect on 
Startup 
The TCP Client will build TCP connection once the connected serial device 
is started.  
Connect on Any 
Character 
The TCP Client will build TCP connection once the connected serial device 
starts to send data.  
Service Mode – UDP Client Mode 
Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you 
can Uni-cast or Multi-cast data from the serial device server to host computers, and the 
serial device can also receive data from one or multiple host.
