The RoamAbout Wireless Ethernet Adapter is easily integrated into your existing wireless network. The RoamAbout Wireless Ethernet Adapter can be used in the following wireless topologies: Wireless infrastructure networks, which require the RoamAbout Access Point. - Page 20 Wireless Infrastructure Network Figure 2-1: Infrastructure Network Example The re-association capabilities of the IEEE 802.11 standard enable clients to move throughout the wireless LAN area and roam between Access Points. Re-association can occur as long as the Ethernet Adapter has the same network name as the AP to which it is trying to make a connection.
- Page 21 Wireless Ad-Hoc Networks Wireless Ad-Hoc Networks Wireless ad-hoc networks, also known as peer-to-peer or independent networks, do not include Access Points. Instead, the ad-hoc network is a loose association, or workgroup, of computers that can communicate with each other using the PC Card in Ad-Hoc Mode. Figure 2-2 shows a network in which three Ethernet Adapter units are used to provide wireless connectivity between Ethernet devices.

Page 55: A Terminal Configurator
This appendix describes how to use the Terminal Configurator to configure the Ethernet Adapter. The Terminal Configurator is an alternate method used to configure your Ethernet Adapter. The Terminal Configurator is a text-based configuration method. You can access the Terminal Configurator by one of the following methods: Through direct serial connection. -
Page 56: Establishing A Direct Serial Connection
Establishing a Direct Serial Connection Establishing a Direct Serial Connection This method of configuring and managing an Ethernet Adapter uses a serial cable connected from the Ethernet Adapter to a computer running terminal emulation software. To configure the Ethernet Adapter using the Hyperterminal program, perform the following steps. - Page 57 10) Choose None for the Flow control option. The serial port settings needed for use by the Terminal Configurator will NOTE always be exactly as described here, regardless of the General Serial Settings (Chapter 11) Click OK after all of the COM settings have been chosen. The next screen appears blank.

Page 58: Establishing A Telnet Connection
Establishing a Telnet Connection Establishing a Telnet Connection This method opens a Telnet connection to the Terminal Configurator on port 23. Port 23 is the default for most Telnet programs. This only works after the Ethernet Adapter is assigned a TCP/IP address. If you need to assign the Ethernet Adapter an IP address you need to use the Ethernet Adapter Manager or the Terminal Configurator using a direct serial connection. -

Page 61: Configuration File Format
Configuration File Format The configuration file format is broken down into sections that define a particular grouping of options. Each section contains at the top a section header which is a string of text surrounded by square brackets: [ ] (the section title). After each section header, there is a list of entries containing equal signs. - Page 62 Using the Terminal Configurator [bridge] Bridge provides variables that are common to all radios. Bridge affects the behavior of radios. AP refresh period. Periodically an Ethernet Adapter pings an Access Point. The AP Refresh Period is the time, in units of seconds, between pings. The default for this value is 60 (which should be left at this default).
- Page 63 [software] The [software] section is used to control the receiving and sending of bytes over the serial port. Proper setting of these values can significantly enhance the efficiency of data transmission because the radio is “packet based” and the UART is “stream based.” Stream based data means that the data is transmitted and received one byte at a time, without any mechanism to separate chunks of data from other chunks of data.
- Page 64 Using the Terminal Configurator transmitted immediately. Conversely, if another character is received before this time-out, the timer is restarted from the beginning. The range for this value is from 10 to 65536 milliseconds, though it will always round up to the nearest tens of milliseconds.
- Page 65 Using the Terminal Configurator [flow control] The Ethernet Adapter supports the following six flow control options: Recognize RTS, Generate CTS, Recognize DTR, Generate DSR, Recognize XON/XOFF, and Generate XON/XOFF. It also supports the original RS-232 specification for flow control where CTS is generated only when RTS is asserted.
- Page 66 Using the Terminal Configurator immediately; otherwise, all of the data thereafter would be lost.) The host computer, however, would have to ask permission from the modem to send data. The host would do this by asserting the RTS line. The modem would see this, and check to see if it were ready to accept data.
- Page 67 CTS and DSR are output lines. When set to “negate” or “assert,” they will output a continuous digital value. The value “negate” outputs a logic 1, or “mark” which is electrically negative. This is also the state seen on an RS-232 connector when the cable is unplugged.

When attempting additional transmit attempts as specified with “transmit try count” above, it can be useful to additionally specify how long to wait between attempts.

- Page 81 This appendix describes how to perform wireless serial line replacement, configure your Ethernet Adapter as a network serial port, and configure your Ethernet Adapter as a serial telnet client. Serial Line Replacement Two Ethernet Adapter’s are required to perform wireless serial line replacement. Serial line replacement can operate with the radio in either Infrastructure or Ad-hoc mode.
- Page 82 Serial Line Replacement To configure for the RMP Pipe protocol, perform the following steps: 1) Complete the Basic Radio Configuration instructions described in If you are replacing a serial line or serial network with two or more Ethernet NOTE Adapter units without using an Access Point, ensure that your radio is using Ad-hoc mode.
- Page 83 Destination Address. This address tells the Ethernet Adapter where to send data received on the serial port. You may enter the RMP address of another Ethernet Adapter for direct serial line replacement. Other possible values are “dynamic” or “broadcast”. Entering “dynamic” causes data to be sent to the Ethernet Adapter from which the unit last received data.
- Page 84 Serial Line Replacement TCP Pipe TCP Pipe, like RMP Pipe, makes no changes to the serial data stream. TCP Pipe differs from RMP Pipe in that it creates two independent network connections for transmitted and received data. Using two connections allows each Ethernet Adapter to detect conditions when it has lost radio contact with the opposite unit, as can occur in environments with poor radio communication.
- Page 85 Network Serial Port This section describes how to configure your Ethernet Adapter as a network serial port. Connection to a network serial port is accomplished over a TCP/IP socket connection. Any program that uses standard TCP/IP network sockets may be used to communicate with the serial port of the Ethernet Adapter.
- Page 86 Network Serial Port TCP Listen Port Configuration Complete the configuration described in and then perform the following steps: 1) Click on TCP Listen Port in the Protocol list. 2) Click on the Listen tab. 3) Type in the port number on which the Ethernet Adapter will listen for a connection.
- Page 87 Serial Telnet Client This section describes how to configure your Ethernet Adapter as a serial telnet client. Telnet is a method to connect and remotely log-in to a host computer or network device. The host computer or device must be running a telnet server for this service to be available. Once the telnet session is established from the Ethernet Adapter, any data received by the serial port of the Ethernet Adapter is sent to the host.
