Introduction

This manual is intended to familiarize prospective customers with Connect One’s
Instant Internet Evaluation Board II-EVB-361MW. The II-EVB-361MW is an
evaluation platform for the Secure Socket iWiFi™ Internet Controller. Secure Socket
iWiFi is a secure serial-to-Wireless LAN device server module that also acts as a
bridge to connect serial devices to 802.11b/g wireless LANs. Secure Socket iWiFi fits
into a socket form-factor and utilizes Connect One’s iChip CO2128SEC Internet
communications coprocessor and the AT+i™ command set, a powerful set of Internet
protocol commands developed by Connect One to manage Internet connectivity
through a wireless LAN connection.

Secure Socket iWiFi enables sending and receiving textual and binary data, MIME­encoded email messages; downloading HTML pages or files from a Web server, or
items from within a page; Web serving, as well as managing TCP or UDP socket
communications (with or without SSL3) over the Internet. It also includes an FTP
client and a Telnet client.

Secure Socket iWiFi supports numerous security protocols like SSL3/TLS1, 64/128­bit WEP encryption, AES-CCM and TKIP encryption, WPA (including AES) and
WPA2.

Unpacking

Take the II-EVB-361MW out of its box. Included in the box are:

 The II-EVB- 361MW motherboard including Secure Socket iWiFi

(iW-SM2128MW)

 A serial cable with two DB-9 connectors
 Antenna
 Power supply adaptor (110V/220V)

Connections

1. Connect one end of the RS232 cable to the serial port on the II-EVB-361MW

(J1) and connect the other DB-9 connector to the COM1 or COM2 serial port
on your PC, or to the serial port of your embedded device.

2. Connect the II-EVB- 361MW to the power supply.

Testing the Secure Socket iWiFi Wireless LAN Connection

To test the wireless LAN connection, you need to configure the Secure Socket iWiFi
to connect to an Access Point:

1. Make sure the Access Point is connected and configured properly.

2. Invoke the iChip Config Utility on your PC.

3. In the main window of the utility, click the Dumb Terminal icon.

4. In the Dumb Terminal window, enter the AT+i command to verify that the

iChip is communicating with your PC. You should receive an I/OK in
response.

II-EVB-361-MW User’s Manual

5

5. Enter the AT+iRP11 command to obtain a report of all the Access Points

available in your area.

6. Enter AT+iWLSI=<ssid>. ssid is the ID of the Access Point you connect to.

Note that ssid is a case-sensitive string.

7. If you want to enable WEP encryption, configure the following parameters:
 AT+iWLWM=<n> where n=0 means no security, n=1 means 64-bit

key, and n=2 means 128-bit key

 AT+iWLKI=<n> where n is the WEP key index (n=1..4)
 AT+iWLK<n>=<keyString> where n is an index between 1 and 4, and

keyString is the WEP key string in the nth position.

8. If you want to enable WPA encryption, configure the following parameter:

AT+iWLPP=<passphrase> where passphrase is the pass-phrase to
be used in generating the WPA1-PSK encryption key

At this stage a connection to the Access Point is established. To test the
connection, use the iChip Config Utility to perform any activity that requires
network connection such as retrieving a web page, sending an email, or
opening a socket.

Installing the II-EVB-361MW Utility
and Evaluation Program

II-EVB-361MW enables you to evaluate the Secure Socket iWiFi without changing
anything in your current development environment. Using a simple terminal program
on a PC, you can issue AT+i commands to the iChip and get responses.

AT+i commands are used to configure parameter values into iChip’s flash memory
and activate Internet tasks such as email send, sockets, FTP sessions, configuration,
and more.

A full description of the AT+i protocol can be found in the AT+i Programmer’s
Manual on the Connect One website in the Documentation section at

http://www.connectone.com.

To help you evaluate the iChip, Connect One supplies the iChip Config Utility. This
is a Windows-based GUI program that contains intuitive dialog boxes to fully
configure iChip. It doesn’t require any knowledge of AT+i commands. It also
contains local firmware upgrade functionality.

The iChip Config Utility also allows you to perform specific Internet communication
tasks such as sending and receiving emails, activating iChip’s websites, entering
SerialNET mode, and more.

The latest iChip Config Utility version and user manual can be found on the
Connect One website at http://www.connectone.com in the Support section.

For more information on the iChip Config Utility and its usage, see the iChip Config
Utility User’s Manual.

Appendix 3: WiFi Configuration Notes

Introduction

Wireless LAN stations operate in one of two modes: Infrastructure or Ad-Hoc.

In Infrastructure mode, wireless LAN stations connect to a wireless LAN Access
Point (AP), which acts as a hub. Wireless LAN stations may connect to each other
through the AP. If the AP is connected to LAN, it allows wireless LAN stations to
connect to other stations on the LAN. When a gateway is in place, it enables wireless
LAN stations to connect to systems across the gateway, as well.

In Ad-Hoc mode, two or more wireless LAN stations communicate directly with each
other.

The Secure Socket iWiFi supports the 802.11b/g wireless LAN communication
platform. It uses the iChip™ CO2128 communication controller chip and Marvell
88W8686 WiFi chipset. It incorporates several dedicated AT+i configuration
parameters to support the wireless LAN environment. See the table below for a
detailed list of WiFi configuration parameters.

AT+i Parameter Name

WLCH

Wireless LAN Communication Channel

WLSI

Wireless LAN System-Set ID

WLWM

WLRS

Wireless LAN Rescan Interval

Table 1: AT+i Wireless LAN Configuration Parameters

The Secure Socket iWiFi may also be configured to exploit WEP security. iChip
supports configuration of both 64-bit or 128-bit WEP keys.

In Infrastructure mode, Power Save mode is supported. When activated, Power Save
shuts down the station for a limited period of time, during which the Access Point
buffers incoming packets destined for the deactivated WiFi station. The station
periodically wakes up to retrieve all the buffered packets stored in the Access Point.
In this mode, total power consumption is lowered at the expense of higher response
latency. The Secure Socket iWiFi may be configured to put the WiFi chipset in Power
Save mode in conjunction with iChip’s inherent Power Save mode.

II-EVB-361-MW User’s Manual

12

iChip Wireless LAN Environment Configuration Parameters

WLCH (Factory Default: 0)

In Infrastructure mode, the WLCH parameter must be set to 0. Other available values
(1..13) designate the preferred communication channel while in Ad-Hoc mode.

WLSI (Factory Default: Empty)

This parameter must be assigned with the System-Set-ID string (SSID), which is
identical to that configured in the Access Point(s) through which the WiFi station
needs to connect. An exception to this is the “Any SSID” configuration, which is
configured by simply leaving this parameter empty (or setting to NULL string with
AT+iWLSI=””). In the “Any SSID” configuration, the WiFi station will connect to
any available Access Point. If more than one Access Point is active, it will choose the
one with the stronger radio signal.

WLWM (Factory Default: 0)

Configure this parameter to designate WEP security usage mode. If WEP is disabled,
the WLKI and WLKn parameter settings are irrelevant. Note that WEP settings (with
the exception of WLKI) must be identical to those configured in the Access Point
device. Possible settings are:

WLWM Setting

WEP Security

0

Disabled

1

Enabled, using 64 bit keys

2

Enabled, using 128 bit keys

Table 2: WEP Security Mode Settings

WLKI (Factory Default: 1)

If WEP is enabled, this parameter defines the key index of the WEP key to be used
when encoding outgoing WiFi packets. Since WEP includes configuration for an
array of four possible keys, WLKI can receive a value in the range [1..4]. The value of
this parameter need not be the same as that configured in the Access Point.

WLKn (Factory Default: All Empty)

These are four consecutive parameters (with n ranging from 1 to 4). The parameters
define an array of 4 WEP security keys, which are used to encode outgoing WiFi
packets (using the key defined by WLKI) and decode incoming packets according to
the key issued by the Access Point device. Key size is 64- or 128-bits, according to
the WLWM setting. The parameter values are used only if WEP security is enabled
(WLWM > 0). The key values must be identical to those configured in the Access
Point device.

WLPS (Factory Default: 0)

This parameter defines the chipset Power Save mode. When configured for Power
Save mode, iChip links its own internal Power-Save mode with that of the Marvell
chipset. When iChip’s Power Save mode is activated (AT+iPSE=1), and when WLPS
is greater than 0, iChip will force the chipset into Power Save mode. The value stored
in WLPS defines the maximum length of time (in milliseconds) during which the
Marvell chipset will snooze, before waking up to download any available packets that
may have been buffered for it in the Access Point. WLPS may be set in the range:

II-EVB-361-MW User’s Manual

13

[0..3600]. When WLPS is set to 0, the Marvell chipset Power Save is disabled, even if
iChip enters Power Save mode.

WLPP (Factory Default: Empty)

This parameter sets the wireless LAN WPA1-PSK pass-phrase to be used in
generating the WPA1-PSK encryption key. When empty, WPA security is disabled. If
WLSI (SSID) is not empty, WPA1-PSK security is enabled for WiFi connections and

WLPP is used in generating the WPA1-PSK encryption key. The allowed value for
WLPP is an ASCII string containing 8-63 characters.

WLRS (Factory Default: 0)

This parameter sets the interval between consecutive scans that iChip performs in
search for nearby ad-hoc networks. Scan duration is two beacon periods (200 ms).
WLRS may be set in the range: 0-65535 milliseconds.

Wireless LAN Configuration Web Site Page

iChip’s configuration website includes two views that support configuration and
status retrieval of related Wireless LAN parameters. The configuration view displays
the configurable Wireless LAN AT+i parameters (WLCH, WLSI, WLWM, and
WLKI). New values may be defined and submitted to iChip from the browser.

Figure 1: Wireless LAN Web Configuration

Wireless LAN Status Report

The Wireless LAN AT+i Report (AT+iRP10) returns pertinent status information
regarding the active 802.11b/g Wireless LAN link. In response to issuing the report
command, iChip will reply with the following syntax:

I/(<port stat>, <xfer rate>, <sig level>, <lnk qual>)

Where,

port stat -- Port Status:

0: Wireless LAN adapter not present
1: Wireless LAN adapter Disabled
2: Searching for initial connection
4: Connected
5: Out of range

xfer rate -- Transfer Rate, in the range 1..4

(1 =>1 Mbps; 2 =>2 Mbps; 3 =>5.5 Mbps; 4 =>11 Mbps)

II-EVB-361-MW User’s Manual

4

11 Mbps

Table 3: Maximum Transmission Rate Command Parameter

When AT+i WLTR is issued, transmission rate is limited for the duration of the
session until another AT+iWLTR command is issued, or iChip is power-cycled.

Placement and Range Guidelines

802.11b/g wireless LAN devices connect to wireless LAN Access Points over a
maximum range of 300 feet. Actual transmission rate and service quality may vary
significantly as a result of environmental obstacles and physical placement of the
Access Point and station devices.

For best results, refer to the following guidelines:

1. Locate the wireless LAN equipment away from sources of interference, such
as PCs, large metal surfaces, microwaves, and cordless phones.

2. Position the wireless LAN access point at an elevated position and as close as
possible to the center of the area in which the wireless LAN devices will
operate.

Wireless LAN Data Privacy/Security Considerations

The fact that wireless LAN devices transmit data over a radio link makes them
vulnerable to electronic eavesdropping, tampering, and information theft. There are
several means by which you may strengthen your wireless LAN access security:

 Change the factory default SSID setting of the wireless LAN Access Point and

station devices. Enable WEP or WPA encryption of the wireless LAN data
communications. If you use WEP, it is recommended that you use 128-bit
WEP keys.

 Restrict 802.11b/g wireless LAN access based on MAC address. This is

configurable in most Access Point devices.

 Place the 802.11b/g Wireless Access Point in a location where it cannot be

physically tampered with.

 Store printed SSID and WEP or WPA key settings in a safe place.
