Overview

1.1

Overview

Including a PC, almost all communication devices are using serial communication.

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.

1.2

Features



Compact Module type



Both Internal (Chip) and External (U.FL socket) antennas are available.



Stable embedded TCP/IP stack



Easy configuration program (ezManager)

1.3

Application Examples
