Hello. If your device has LAN port, you can connect to host directly without CSE-H53N. But If you want to use RS232 port, TCP connection is needed between CSE-H53N and host. Here are Examples. 1. [CSE-H53N] Server IP address: 192.168.1.2 Local port: 1470 [Host with socket program] Client IP address: 192.168.1.3 Peer IP address: 192.168.1.2 (server IP) Peer port: 1470 (server port) 2. [CSE-H53N] Client IP address: 192.168.1.2 Peer IP address: 192.168.1.3 (server IP) Peer port: 1470 (server port) [Host with socket program] Server IP address: 192.168.1.3 Local port: 1470 If TCP connection is established, STS LED of CSE-H53N will be on. After that, You can send data from RS232 to LAN and vice versa.
