LanConn-400 User’s Guide

1. Description

LanConn-400 is a full duplex serial port to Ethernet converter. Through LanConn-400, your system

can easily communicate with the LAN, WAN or Internet via the RS232/RS422/RS485 port. When

sending data to the network, LanConn-400 automatically adds the necessary TCP/IP stack. When

receiving data from the network, LanConn-400 automatically removes the TCP/IP stack.

LanConn-400 also provides a device interface with 4 serial ports and 1 keyboard port, making it a

powerful and cost effective solution to many applications such as industrial automation and remote

(Internet enabled) device control.
