The WiSpan is an industrial 802.11 b/g wireless-to-Ethernet bridge allowing 10/100 Ethernet-enabled devices to seamlessly connect and communicate over

802.11 b/g wireless networks. By bridging 10/100 Ethernet to 802.11 b/g, wireless mobility can be added to Ethernet devices.

The WiSpan Ethernet bridge connects or bridges Ethernet devices to wireless networks using the IP protocol.

Note: The Ethernet interface can only bridge a single wired device.

Typical applications of the WiSpan include:

 Cash registers  POS terminals  Vending machines  Industrial equipment  Security panels

Protocol Support

The WiSpan Ethernet bridge uses the TCP/IP protocol stack for network communications. Other supported protocols include:

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

communications and management.

 TCP, UDP, and Telnet for connections to the setup 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

that support UDP interact with other devices without maintaining a point-to-point connection.

Configuration Methods

For the unit to operate correctly on a network, it must have:

 An IP address  Appropriate settings for network communications to an access point

(Infrastructure Mode) or for peer-to-peer connection (Ad Hoc Mode).

Methods for logging into the WiSpan to set configurable parameters include:

WiSpan User Guide 8

2: Introduction

Serial & Telnet Ports: There are two approaches to accessing Setup Mode: make a Telnet connection to the network port (9999) or connect a terminal (or a PC running a terminal emulation program) to the unit’s setup (serial) port.

DeviceInstaller: This utility provides a GUI interface for locating the WiSpan on the network, assigning an IP address, viewing the current configuration, and updating firmware.

Web-Manager: Once the unit has an IP address, you can configure the WiSpan and its settings using the WiSpan’s web interface, Web-Manager.

The WiSpan has one setup (serial) port and one Ethernet port for setup and for connecting an Ethernet device using a network crossover cable. It has an 802.11 b/g transceiver that connects to another wireless device or to an Access Point (AP).

Following is a description of the serial and Ethernet connectors.

Serial Connector Pinouts

One DB9M DTE setup port provides default settings for RS-232C communications of 9600 baud, 8 bits, no parity, and 1 stop bit (9600, 8, N, 1). The only use of this port is to configure the unit in Setup Mode.

Figure 3-1. Back of the WiSpan

Setup Port

Figure 3-2. DB9M DTE Serial Connector

Network Interface

The back panel of the WiSpan contains a 9-30 VDC power plug and an RJ45 (10/100) Ethernet port. You may use the Ethernet port to configure the unit as well as to connect a network-enabled device to the network using a network crossover cable.

44::QQuuiicckkSSttaarrt

This chapter describes how to install and configure the WiSpan unit to get it up and running. You must configure the WLAN settings for the WiSpan to communicate on a wireless network.

Note: You only need to configure the WiSpan's IP address and other network settings if

you want to discover and configure your WiSpan device from the wired network; these settings only apply to communication on the Ethernet interface.

Installing the WiSpan for Configuration

There are two methods for installing the WiSpan so that you can configure it:

Using the Setup Port

To connect to and initially configure the WiSpan using the setup port:

1. Connect one end of the supplied DB9F – DB9F null modem serial cable to the WiSpan’s setup port.

2. Connect the other end of the DB9 serial cable to a terminal or a PC’s serial COM port.

3. Continue with Using Setup Mode for Server and WLAN Configuration, below.

Figure 4-1. WiSpan Connected for Configuration via the Serial Port

WiSpan User Guide 13

Using the Ethernet Port

To connect to and initially configure the WiSpan using the Ethernet port:

1. If a device is connected to the WiSpan's Ethernet port, disconnect it and connect a PC for configuring the WiSpan.

2. Set up the PC's Ethernet port for AutoIP or assign a static IP address in the AutoIP range (169.254.x.x).

3. Use a utility such as DeviceInstaller to locate the WiSpan’s MAC address and IP address. This utility must use the Lantronix access protocol to query the WiSpan. (See 5: Using DeviceInstaller.)

4. Use the WiSpan’s Web-Manager (see 6: Web-Manager Configuration) or Telnet to port 9999 to configure the WiSpan.

Note: Telneting to the WiSpan accesses Setup Mode. The procedure for

using Setup Mode from the Ethernet port is the same as for using the setup port, described below, starting with step 3.)

5. Disconnect the PC and reconnect the original device to the WiSpan's Ethernet port.

Using Setup Mode for Server and WLAN Configuration

To use Setup Mode for configuration:

4: Quick Start

1. With a connection to the setup port, open a terminal emulation application (e.g. HyperTerminal) on the PC. The default serial settings are 9600 baud, 8 bits, no parity, 1 stop bit, and no flow control (9600, 8, N, 1).

2. Enter Setup Mode by simultaneously connecting the power supply and holding down the x key. Upon connection, information similar to the following displays:

Figure 4-2. Setup Mode

*** Lantronix WiSpan Device Server ***

MAC address 00204A89468C

Software version V6.5.0.2T4 <070221>

Press Enter for Setup Mode

3. Press Enter within 5 seconds to display current settings followed by the Change Setup menu.

Note: Current values display in parentheses.

Figure 4-3. Change Setup Menu

Note: For initial configuration, only WLAN settings are required. To configure these

settings only, start with WLAN Settings on page 16.

WiSpan User Guide 14

4: Quick Start

Server Settings

To configure the Server (WiSpan) settings, select 0 Server from the Change Setup menu.

The unit’s basic server (network) values display when you select Server (option 0 from the Change Setup menu). The following sections describe the configurable parameters within the Server configuration menu.

Network Mode: The network mode (Bridging <One Host>).

Set the IP Address: The unit has an automatically assigned IP address. To assign a

static address, enter it manually. The IP address must be set to a unique value in the network. Enter each octet and press Enter between sections. The current value displays in parentheses.

IP Address : ( 0) ( 0) ( 0) ( 0) _

Set the Gateway IP Address: The gateway address, or router, allows communication to other LAN segments. The gateway address should be the IP address of the router connected to the same LAN segment as the unit. The gateway address must be within the local network.

The default is N (No), indicating the gateway address has not been set. To set the gateway address, type Y. At the prompt, enter the gateway address.

Set the Netmask: A netmask defines the number of bits taken from the IP address that are assigned for the host part.

Netmask: Number of Bits for Host Part (0=default) (0) _

The unit prompts for the number of host bits to be entered, then calculates the netmask, which displays in standard decimal-dot notation when the saved parameters display (for example, 255.255.255.0).

Table 4-1. Standard IP Network Netmasks Representing Host Bits

Network Class Host Bits Netmask

A 24 255.0.0.0

B 16 255.255.0.0

C 8 255.255.255.0

Change Telnet Configuration Password: Change the Telnet configuration password to prevent unauthorized access to the Change Setup menu and Web-Manager.
