Page 6: Overview
Devices transmit and receive data in bit order in the serial communication which is quite simple to implement but has weaknesses such as short distance and hard maintenance. CSW-M85 is a module-typed converter enables serial devices to support TCP/IP communication through wireless LAN (IEEE 802.11b/g/n). CSW-M85 carries out the converting process for users to get to the network using TCP/IP protocol. -

Page 33: Communication Modes
Communication Modes TCP Server In this mode CSW-M85 listens to a request of TCP connection from remote hosts. Once a host tries connecting to CSW-M85, it accepts a connection. After the connection is established, CSW-M85 converts the raw data from the serial port to TCP/IP data and sends it to the network and vice versa. -

Page 37: Tcp Client
In this mode, CSW-M85 sends request segments to a TCP server with information of [Peer Address] and [Peer Port]. Once a host is listening, the connection will be established. After then, CSW-M85 converts the raw data from the serial port to TCP/IP data and sends them to the network and vice versa. -
