1 Overview

1.1 Overview

Most industrial devices support standard serial communications, where callers transmit

bitstreams to receivers in sequence. Although serial communication is known as simplicity,

it is not widely used in modern computing environments due to its short distance and

frequent maintenance requirements.

By providing an Internet connection to a serial communication device, the CSW-H85N

can overcome this limitation. Especially with the TCP / IP stack and serial communication,

the CSW-H85N converts serial data to TCP / IP data, and vice versa.

1.2 Features

⚫ connect serial devices to IEEE 802.11b/g wireless LAN

⚫ IPv4/IPv6 dual stack

⚫ multi-monitoring (4 connections)

⚫ SSL (Secure Socket Layer)

⚫ Soft AP mode: support WEP and simple DHCP server

⚫ various WLAN securities: WPA-PSK, WPA-Enterprise (EAP-TLS/TTLS, PEAP)

⚫ 1 serial port for RS232, RS422 or RS485 interface

⚫ RP-SMA connector for an external antenna

⚫ stable embedded TCP/IP stack

2 Installation and Test

2.1 WLAN Overview

CSW-H85N supports IEEE 802.11b/g standard, which is called Wi-Fi. It has three network

topologies; Infrastructure, Ad-hoc and soft AP mode. You can set one of these topologies

on the [Wireless LAN] tab of ezManager



You can download ezManager on our website.

Figure 2-1 setting WLAN topology

2.1.1 WLAN mode: Infrastructure

In this mode, every wireless LAN station communicates through an Access Point (AP) so

that all stations can be connected to Ethernet, because AP is able to interface witch both

wireless LAN and wired LAN (Ethernet).

Figure 2-2 infrastructure mode

CSW-H85N User Manual Ver. 1.3

- 15 -

https://www.ezTCP.com

2.1.2 WLAN mode: Ad-hoc

Wireless LAN stations communicate each other without an AP in this mode. Therefore,

you can easily make this network. It is suitable for the situation when there is no wired LAN

requirement on a small-scale network. Usually, it is called peer-to-peer mode.

Figure 2-3 Ad-hoc mode

2.1.3 WLAN mode: Soft AP

Soft AP (Software embedded Access Point) is a mode that a wireless client can act as an

AP through software embedded AP functions. Using this mode, a wireless client allows

communicate with not only laptops and smart phone but also devices which don’t have

Ad-hoc function.



Caution: Even in the Soft AP mode, CSW-H85N does not work as a general Access

Point. Note that the stations, which is connected to the Soft AP, cannot

communicate each other through CSW-H85N. They are allowed to communicate

with CSW-H85N only.

CSW-H85N supports Soft AP function. While operating in this function, it has 10.1.0.1 as

its IP address and assigns an IP address of 10.1.X.X to each of clients.

Figure 2-4 Soft AP mode

CSW-H85N User Manual Ver. 1.3

- 16 -

https://www.ezTCP.com

Although this function is automatically operated in Serial Configuration mode, you can

set manually on [Wireless LAN] tab of ezManager.

2.1.4 Key terms

⚫ SSID (Service Set Identifier)

It is a name to identify the particular wireless LAN. So, every single station should

have the same SSID to communicate in the network. In the case of infrastructure

mode, you have to set the same SSID with the AP to CSW-H85N. Otherwise, it will

not communicate at all. The maximum length of this parameter is 31 bytes. The

default value of SSID is “sollae”.

⚫ Channel

Wireless LAN stations communicate through the ISM (Industrial, Scientific, and

Medical) band which has the range of frequencies around 2.4GHz. IEEE 802.11

specification divides this band into 14 channels in every 5MHz. If you install more

than one wireless network in the same area, the channels should be apart more than

4 channels to avoid interferences.

2.1.5 Authentication and Security

⚫ Authentication

A wireless LAN station should get authentication from the AP in the infrastructure

network. There are two methods for the authentication and those are Open System

and Shared Key.

⚫ WEP (Wired Equivalent Privacy)

The WEP is a secure protocol for wireless LAN. You need to set 64-bit or 128-bit key.

You can use both hexadecimal and ASCII code for this.

⚫ WPA (Wi-Fi Protected Access)

WPA is a security standard for users of devices equipped with Wi-Fi wireless

connection. It is an improvement on and is expected to replace the original Wi-Fi

security standard, Wired Equivalent Privacy (WEP). There are two modes about the

user authentication in WPA security. One is Enterprise which has an authentication

server and the other is PSK (Pre-Shared Key) which does not have any servers.

⚫ WPA2

To final security of Wireless LAN, IEEE 802.11i which is a standard about Wireless LAN

has suggested the Counter Mode with Cipher Block Changing Message

Authentication Code Protocol (CCMP) for replacing the TKIP. CCMP uses Advanced

Encryption Standard (AES). WPA 2 adopts AES. WPA 2 has also both Enterprise and

PSK mode.

2.2 Installation

Before testing CSW-H85N, make sure that a connection between your PC and CSW-H85N

is established via Serial and wireless LAN. This section is an example which is based on

Infrastructure mode.

Figure 2-5 WLAN and RS232 connection with a laptop

2.2.1 Connect CSW-H85N to an AP

When you connect an AP or wireless LAN adapter to your PC, Wireless LAN link is not

automatically established. Therefore, its parameters should be set on CSW-H85N

beforehand.

⚫ Setting by Serial

① Supplying Power to your CSW-H85N

② Make your CSW-H85N operate in the Serial Configuration mode

Press the function button shortly.

③ Reading current settings of CSW-H85N through the serial port

Open a COM port of [Serial] tab on ezManager and press [Read] button.

④ Configuring Wireless LAN Parameters

Figure 2-7 [Wireless LAN] settings on ezManager

Check the [WLAN topology] is selected to [Infrastructure]. Input the SSID of your AP

to the [SSID] item. Note that the SSID is case-sensitive. If your wireless network has a

security option, input the passphrase to [Shared Key] item. After setting all, save the

settings by clicking [Write] button. If your CSW-H85N is successfully connected to the

AP, LINK LED on the top panel will be turned on.

https://www.ezTCP.com

⚫ Setting by Soft AP

In case that you cannot use serial port, Soft AP function allow you to set those

parameters as follows;

① Supplying Power to you CSW-H85N

② Make your CSW-H85N operate in the Serial Configuration mode

Soft AP is automatically activated when products are under Serial Configuration mode.

③ Connecting to Wi-Fi using Soft AP

Connect laptop or smartphone to Wi-Fi network made by product's Soft AP function.

The SSID is "cfg_MAC Address". (e.g. cfg_0030f9000001)

Figure 2-8 Connecting to Wi-Fi using Soft AP

④ Connecting to the CSW-H85N with a Web browser

Run a web browser and connect to 10.1.0.1. The setting parameters are the same with

the setting by serial.
