4.2 TCP Client mode
1. In TCP Client mode, USR-N580 can actively establish a TCP connection with a server computer. Once the
connection is established, data can be transmitted in both directions between the serial device and the
server.
2. Identify disconnects. After connection established, it sends keepalive searching packet every 15 seconds.
Once there is an interrupt, it can be detected rapidly then make USR-N540 disconnect from former
connection and reconnect.
3. TCP Client mode supports RFC2217, USR Cloud and short connection function.
4. Under the same LAN, please ensure the IP address and gateway are in the same network segment if the
N580 is set to a static IP address.
5. In this mode, N580 can connect to the same LAN’s IP address or a public IP and domain name.
6. It is recommended to set the local port of N580 to 0 to avoid reconnection failures caused by server
determination of connection status anomalies.
7. Test example:
Set the N580 to TCP Client, Remote server address: 192.168.0.201, Remote port: 8234. Save and Restart
the device.
