410S Function Diagram
4.1.1 TCP Client Mode
1) Different from UDP mode, its connection can be disconnected and kept.
2) Identify disconnects. After connection built, it sends keepalive searching packet every 15 seconds.
Once there is an interrupt, it can be detected rapidly then make 410S disconnect from former
connection and reconnect.
3) It will connect to same source port when 410S try to connect server and local port is not “0”.
4) It supports USR Synchronous baud rate (Similar RCF2217), which can revise 410S’ serial
parameter as baud rate accordingly. This function should be combined with USR-VCOM.
5) Within same LAN, 410S must be in the same network segment then can communicate. If not, 410S
must be set with right one.
6) Support USR Cloud.
