vi Wi232/WiUSB User Guide

1. Overview

Wi232 is a wireless embedded device server that provides serial-to-wireless network connectivity. Wi232
allows virtually any RS232 serial device or equipment to be remotely accessed, controlled, monitored or
shared on an 802.11b wireless network.

The Wi232 functions independently of a PC, providing a fully integrated solution that combines a processor,
memory, 802.11b transceiver, Ethernet port, and a high-speed serial port into a single compact module. It
includes an operating system, an embedded Web server, full TCP/IP protocol stack and WEP/WPA security.
In addition, the Wi232 supports numerous other network communication protocols, including ARP, UDP,
TCP, ICMP, Telnet, AutoIP, DHCP, HTTP, SNMP, and SMTP.

For designers who wish to customize the user interface by employing common and familiar tools, the Wi232
serves applets to a Web browser, resulting in interactive Web pages. This customization of HTML Web
pages and configuration screens tailors the Wi232 to fit unique requirements.

The Wi232 device server has the following capabilities:

• Communication between TCP and UDP to serial.

• Wireless interface (802.11b or Ethernet interface.

• Upgradeable firmware.

• SNMP monitoring.

• Connects devices through a TCP or UDP data channel to computers or to another de vice server.

• Contains a web server allowing presentation of custom content and easy configuration through the

browser.

Some of the devices are:

• ATM Machines

• CNC Controllers

• Data Collection Devices

• Universal Power Supply (UPS) Management Units

• Telecommunications Equipment

1.2 Application Examples

The Wi232 has a serial port, an Ethernet port and an 802.11b transceiver. You can enable either the Ethernet
port or the Wireless LAN. The serial port connects to the serial communication port of your device. The
wireless transceiver connects to another wireless device or to an Access Point (AP) connecting to a network
through an Ethernet link.

This section includes four typical scenarios for using the Wi232.

Figure 1 - Serial Tunneling Example

Ethernet

Personal Computer (PC)

Wireless Laptop Wi232

POS Device

A PC connected to an Access Point via an Ethernet connection and a laptop with a wireless connection to
the Access Point LAN access the Wi232 as though they are directly connected to it. The combination of the
Wi232, a PC, and Redirector software allows the PC to directly communicate to the Wi232’s serial devices,
providing wireless serial tunneling.

Figure 2 - Ad-Hoc Network Example

Wireless Laptop

POS Devi ce

Wi232

In the above example, the Access Point is not present. The laptop makes a direct wireless connection with
the Wi232 to manage serial devices. Without an AP, it is a peer-to peer relationship.

In the above example, the Wi232 communicates with another device server via the Access Point. The
NET232 device server, in this example, is connected via an Ethernet connection to the Access Point. As
such, the Wi232 and the device server communicate directly and can transfer information between their
serial devices. This configuration is called Infrastructure mode.

In the above example, two Wi232s have established an Ad-Hoc peer-to-peer relationship. They
communicate directly to each other’s serial devices without a PC or an Access Point.

Note: How do you set up the units for point-to-point? See Application Note, Wi232 Serial Tunnel, GC-800-302.

1.3 Protocol Support

The Wi232 uses the Internet Protocol (IP) for network communications and the Transmission Control
Protocol (TCP) to assure that no data is lost or duplicated, and that everything sent to the connection arrives
correctly at the target.

Other supported protocols include:

• ARP, UDP, TCP, ICMP, Telnet, TFTP, AutoIP, DHCP, HTTP, and SNMP for network

communications and management.

• TCP, UDP, and Telnet for connections to the serial port.

• TFTP for firmware and web page updates.

• IP for addressing, routing, and data block handling over the network.

• User Datagram Protocol (UDP) for typical datagram applications in which devices interact with

other devices without maintaining a point-to-point connection.

2. Quick Start

This section describes a procedure for quickly installing the Wi232 through the serial port.

2.1 Required Information

2.1.1 Hardware Address

You need to know the unit's hardware address (also known as MAC address), which is on the manufacturers
ID label on the bottom of the unit. It is in the format: 00-20-4a-XX-XX-XX, where the XXs are unique
numbers assigned to the product.

Hardware Address: 00-20-4a- ____ - ____ - ____

2.1.2 WLAN Settings

Your Wi232 must have a unique IP address on your network. The systems administrator generally provides
the IP address and corresponding subnet mask and gateway. If you leave the IP address set to 0.0.0.0, the
Wi232 will attempt to get a DHCP address from the wireless Access Point or network server. If it cannot get
a DHCP address, it will use AutoIP to assign an IP address.

Before the Wi232 can communicate on an 802.11b wireless network, the WLAN settings must match the
wireless network. By default, the Wi232 is set to Infrastructure network mode and its wireless Network
Name (SSID) is LTRX_IBSS. You will need to change the Network Name (SSID) to the name used by
your wireless Router or Access Point.

IP Address: _____ _____ _____ _____
Subnet Mask: _____ _____ _____ _____
Gateway: _____ _____ _____ _____
WLAN SSID ________________________ (case sensitive)
WEP Enabled Y/N _________

Wi232/WiUSB User Guide 2-5

Open the client manager for the wireless adapter to setup a configuration profile. You can generally access
the client manager icon in the tool tray.

Verify the client manager has the following settings:

• Connected to network: GRIDCONNECT (or your specific network name)

Verify that the wireless adapter is connected to the Access point and has a good signal.
At this point, you should be able to access the Wi232 through a wireless connection.

• If you assigned the Wi232 an IP address, you can use the Web-Manager in Device Installer to

configure the unit to work with your application. Before you do that, you may want to try the Quick
Test in the next section to verify the unit can send and receive data between the serial port and the
Ethernet port. Continue with Configuration Using Web-Manager on page 3-1.

• If you did NOT assign an IP address, and allowed the unit to acquire a DHCP or AutoIP address,

then you will need to locate the unit on the network and determine the IP address. The best way to
locate the unit is with the Device Installer utility included on the software CD. Please read the
Device Installer User Guide, Dev_Inst_UG_800233_x.pdf, before installing the software.

• Once you determine the IP address, try the Quick Test in the next section to verify the unit can send

and receive data between the serial port and the Ethernet port. You can continue to configure the
device by going to Configuration Using Web-Manager on page 3-1.

To configure the Wi232 with a serial port connection, see Configuration via Serial Mode or Telnet Port on
page 4-1.
