for roaming after moving to a segment different in IP over beyond
the router.

Multi-channel correspondence

Supports multi-channel operation. The channel settings can be
changed to separate each network group.

Number of units

Each master AP can manage a maximum of 256 APs (including the
master AP).
Each AP can connect to a maximum of 254 UU/STs at one time.
An AP can manage a maximum of 2048 UU/STs including
tunneling UU/STs.

FX-DS110-APE

Roaming Function

The roaming function maintains the connection to the LAN by
automatically changing the access point to which the user unit is
connected when the unit moves. If access points are positioned so
as to cover the entire area where the wireless LAN is to be available,
the user unit can be used from anywhere.

When the operation mode of a FLEXLAN-DS110 user unit is
“Infrastructure”, it is designed to continuously monitor the AP
(access point) signal strength and change to the AP that provides
the most reliable communications.

In the following example, the signals from the APs do not cover the
entire range in which the mobile station U1 moves and therefore the
connection to the wired LAN is lost when U1 is in position (2).

IP Tunneling Function

In TCP/IP, packets belonging to different network groups cannot
normally be used. However, a technique called tunneling or IP
tunnel technology can be used to temporarily modify packets
belonging to different network groups so that they can be used.
This technique can enable user units to communicate with the wired
LAN as usual even when connected via an AP from a different
network group.

The following example shows how user unit U1, which belongs to
network group A, can connect via a router to terminal PC1, also in
network group A, despite U1 being connected to the LAN via AP2
which belongs to network group B.

constructed using AP connections.

- Advantages
(1) Requires virtually no setup work to start.
(2) Can bridge multiple wired LAN's, allows duplication of

lines.

- Disadvantages
(1) When the AP is a relay point the available communication

range is narrower than in Infrastructure (Standard Mode).

20

(2) Not suited to construction of large wireless LAN

environments.

FX-DS110-APE

Note!

About FLEXLAN-DS110 Series

When configuring a wireless LAN in simple (ADHOC) mode, be
sure to place all wireless terminals within effective communication
range. If units are too far apart, communications can be hindered
by partitions or other obstacles causing some terminals to be
unreachable and reducing system throughput.

Figure 3.5. Infrastructure (Standard Mode)

In the above standard mode, all wireless terminals communicate via
unit type APs. Roaming functions are supported, allowing logged
in on any unit type AP.

For IP tunneling to work correctly, one of the APs must be setup as
the master AP (See “Setting Item List” in Chapter 6).

- Advantages
(1) Allows multiple AP's to be set up to configure wide-are

wireless LAN's.

22

(2) If the IP tunneling function is used, communication can

continue via different routers without needing to change IP
address.

(3) Allows log-in restrictions on unit type AP's (security

function).

- Disadvantages
(1) All AP's must be IP controlled, requiring many settings.

Figure 3.8. Brouter Mode

In brouter mode, all wireless terminals communicate via the unit
type AP. As the AP functions as a router, the wireless LAN can be
disconnected from the wired LAN to reduce the traffic on the
respective networks.

- Advantages
(1) Because the AP functions as a router, the wireless and wired

networks can be disconnected.

(2) Broadcast packets are not passed to the wired LAN.

- Disadvantages
(1) As the roaming and IP tunneling functions cannot be used,

this mode of operation is suitable for relatively small
wireless LANs.

Figure 3.9. Interconnection Mode

Like standard mode, all wireless terminals communicate via unit
type APs in interconnection mode. As the roaming function is
supported, terminals can log in to any unit type AP within range.

As the unit type APs operate as simple bridges, proprietary FX­DS110-APE functions cannot be used.

APs with the station unit type can log in to APs from other vendors
that support Wi-Fi. In this case, only one terminal can have a
wired connection to the station AP.

- Advantages

FX-DS110-APE

About FLEXLAN-DS110 Series

Applicable scope

As roaming is not available in simple mode (ADHOC connection),
the devices that are to communicate via wireless must be located
within radio range. This restricts the applicable scope of this
mode. Standard mode is typically used for medium to large sized
wireless LANs.

A “-“ mark is specified for inter-segment brouter mode as this
configuration consists of APs linking between segments and does
not include any user units.

Roaming

The roaming function which allows mobile user units to switch log­in between multiple APs can only be used in interconnection mode
and standard mode. Roaming can be used to construct large scale
wireless LANs.

IP tunneling

This function modifies the IP address so that units can connect to
the desired network group even via APs belonging to different
network groups. This function can only be used in standard mode.

IP routing

This function performs routing of IP frames. The AP operates as a
bridge for non-IP frames.

Bridge OFF

If the bridge function is set OFF when using the IP routing function,
the AP does not operate as a bridge for non-IP frame packets.

Spanning tree

A function for avoiding network loops. A spanning tree can be
used to provide duplicate circuits over the wireless network where
one of the circuits is used as a backup. Details are explained in
Chapter 8.

DHCP

This function automatically allocates an IP address to wireless
devices that log in the AP.

FX-DS110-APE

29

About FLEXLAN-DS110 Series

SNMP

This function enables remote management by software that supports
SNMP. Available in all modes. See Chapter 9 for details.

Automatic firmware update function

This function automatically gets the latest firmware from the master
AP.

Log collection function

This function lists the wireless terminals logged in to the AP and
collects times and other event information. See Chapter 7 for
details.

Data encryption

This function encrypts wireless data. Two encryption methods are
available: proprietary scrambling and WEP. Proprietary
scrambling and WEP can both be used at the same time. However,
communications cannot be performed between devices that use
encryption and devices that do not.

Installation in a Network

This section describes how to install the FX-DS110-APE to
construct a network with improved performance and discusses the
general features and radio characteristics of the wireless LAN as
well as the guidelines for constructing the network.

Features of the Wireless Network

In general, the operation of a wireless network is the same as for
most other types of LAN. The most prominent feature of the
wireless network is that it uses radio waves as its medium,
eliminating the need for cabling. The wireless network thus requires
no cabling cost and has other advantages as listed below:

- Quick construction of a LAN

- Temporary installation of a LAN

- Higher flexibility in layout of connected PCs (terminals)

- Assured mobility of connected PCs (terminals)

On the other hand, the wireless network has the following drawbacks
from the operational point of view due to the nature of radio waves:

Installation Method

- Signal attenuation

- Signal interference

Also, although this unit does not require a radio license, it is subject
to radio regulations.

Installation Method

Operating Environment and Radio Waves

When using this product to construct a network, install and operate
it considering the radio environment to optimize the performance.

Is allowed to use radio equipment at the installation location?

In some medical institutions and laboratories, radio-sensitive
precision instruments are used and it may be prohibited to use radio
equipment.

Radio waves are attenuated.

Although a radio wave is attenuated naturally as it travels from its
transmission source, it may also be attenuated by an object existing in
its way. Major obstacles that attenuate radio waves are as follows:

- Concrete wall

- Metal surfaces in the vicinity of the antenna

Obstacles blocking radio waves include metal walls and walls
containing a metal firewall.

Strictly speaking, nearly all objects in the path of the radio waves
(such as partitions or people) cause some attenuation but these do
not have a significant impact on network performance.

40

RSSI (Receive Signal Strength Indication) utility is available as a
means of knowing the signal strength of an incoming radio wave.
Placing this product for a greater RSSI value makes the
communication state more stable. If the RSSI value is small and
slightly moving the position of the product does not increase the
RSSI value, it indicates radio wave attenuation either to the distance
or by an obstacle.

FX-DS110-APE

Installation Method

Pay attention to radio interference.

Radio interference means the reception of radio waves in the
frequency band used by this network that are generated by
equipment that is not part of the network to which this product
belongs. Listed below are major examples of sources of
interfering radio waves generated in general environments
excluding plants and factories:

- 2.4GHz band wireless networks that do not comply with

IEEE802.11

- Non-network sources of radio interference

- Microwave ovens

- Security gates

(Installed near the entrances of some department stores and rental
shops)

- Copiers

Where there is a large metal wall such as in a warehouse, the radio
wave generated from the sender is reflected, resulting in those radio
waves reaching the receiver which have taken different routes
(thereby phase-shifted). This has the similar effect as the generation
of interfering radio waves, possibly slowing down data transfer.

Most of the interfering radio wave sources other than wireless
networks have local and/or temporary effects, not so affecting
network performance. Rarely, however, the date rate is reduced
and, in the worst case, communication is disabled temporarily. In
such cases, change the location of this product and the channel used
for communication. This may solve the problem.

Constructing a Network

This section gives some pointers and cautions relating to
constructing a network using the AP and user units, and provides
some practical examples.

(1) Give some though to the area in which the radio signals need

be received (henceforth called the coverage area). (In this
section, the coverage area will mean the region in which the
RSSI value is 80 or higher.) For example, if the AP is used in
standard mode with multiple user units logged in, all user units
must be located within the coverage area. As the
communication range of the AP is about 50m in an indoor
environment with no obstructions, approximately this area can
be covered in a typical office or factory provided no concrete
walls, metal doors, elevator shafts, or similar are present.
However, remember that transmit and receive errors start to
increase as the transmission distance gets longer.

When setting up the network, check the RSSI level then
confirm that communication works correctly with the
application you plan to use. For a TCP/IP system, for
example, you can use the Windows PING command. To use
PING, open an MS-DOS prompt window and enter the
following command. The example command is for an AP
with an IP address of 10.168.132.15.

42

 C:\WINDOWS>ping 10.168.132.15

(2) The maximum number of user units that can log in to an AP at

one time is 254. However, remember that the communication
speed slows due to the increased loading as the number of user
units for a particular AP increases.

(3) The DS type communications used on this AP can be set to any

one of channels 1 to 14 by RF. However, signal interference
may occur if another network group is operating nearby using
a channel number close to the selected channel number. It is
recommend that the channels used for adjacent networks are
separated by at least 5 channels.

FX-DS110-APE

Installation Method

(4) If a pair of wireless terminals are communicating via a

particular channel, no other communications can use that
channel within the range of the radio signal (the exception is
broadcasting which transmits to all terminals). As a result,
communication speed tends to drop as the density of wireless
terminals increases although this depends to a large extent on
how frequently the network is used.

(5) If the AP is connected to an Ethernet hub or similar, a

unexpectedly large load can occur on the AP if the Ethernet
traffic is heavy and this may reduce the performance of the
wireless network. This can be solved by changing the hub
connected to the AP to a switching hub (bridge).

(6) Setup the software in accordance with how the network will be

used.

(7) The communication speed may also drop due to interference if

two wireless terminals are located close to each other. In
general, maintain a gap of about 1m between user units, 3m
between APs and user units, and 3m between APs.

(8) The best performance is achieved from antennas if they are

located in an open space free from obstructions. Avoid
locating antennas where they will be hidden. In particular,
when communication distance is an important consideration, it
is recommended that you install antennas in a high location
with a clear view.

(9) Floors often contain steel beams or metal firewalls and

therefore communication between floors is often not possible.

FX-DS110-APE

43

Installation Method

Example 1 Using standard mode

This example constructs a network with 48 user units. Although
the small area to be covered means that one AP should be enough,
two APs are used to provide a backup and to ensure a reasonable
level of communication speed. If AP1 or AP2 is down, the
roaming feature allows user units to log in to the other AP and so
provides a backup network connection. Also, as notebook PCs are
often brought to the meeting room and used to exchange data and
access the server, and as the concrete walls of the meeting room
block radio signals and result in a low RSSI value, another AP is
also located in the meeting room.

Each of the APs has a wired connected to the Ethernet network.

Example 2 Duplex circuit using simple mode

This example uses APs to provide a wireless connection between
the networks in buildings A and B. Although a connection could
be provided using just two APs, an extra backup AP is installed in
each building to provide better reliability. The AP’s spanning tree
function is used to avoid a network loop problem being caused by
the backup path. To avoid the shadow of building pillars, the APs
are located so that they are facing each other through glass windows
and are separated by at least 3m. The RSSI value for the signal
from the opposing AP is confirmed to be 80 or higher and a
switching hub is used to minimize the load on the APs.

Figure 4.11. Medium-Sized Wireless LAN

This example constructs a wireless LAN operating over three floors
of a building. A different department is located on each floor and
these are separated by routers.

User PC1 belongs to the 3rd floor but sometimes takes his PC and
works on the1st floor. As the IP tunneling server function is
enabled on the AP, PC1 can still perform operations such as sending
and receiving mail and accessing the 3F file server while roaming
on the 1st floor away from the 3rd floor router.

To keep the various APs separated, the APs on different floors are
installed on opposite sides of the building so that they are not
directly above or below each other.

5. Setup Preparation

This chapter gives an overview of how to setup the AP and
describes how to access the AP settings using a web browser or
terminal.

Setup Methods

Various detailed settings for configuring a high-performance
wireless LAN can be set on the AP using either a terminal or web
browser.
The key features of each setup method are as follows.

Terminal

- Setup can be performed even from older PCs.

- The terminal or other device used for setup must be directly

connected to the AP.

- As setup operation is text-based, it is more difficult to use.

WWW browser

- Provides an easy to use graphical interface.

- Setup can be performed remotely (via a LAN or modem).

- Independent of PC platform (type of OS, etc.).

- Requires that the network IP address of the AP be the same as the

network IP address of the PC used for setup.

- Web browsers can only be used on relatively modern PCs.

Setup Using a Web Browser

You can setup the AP software from a PC running a web browser
via the LAN or a modem. As this provides a graphical interface,
setup using a web browser is much easier than using a terminal.

The factory default IP address for the AP is listed on the underside
of the case. You can use this address to connect to the AP from a
web browser but this requires that you change the IP address of the
PC to be in the same network group as the AP’s IP address (when
finished, set the IP address back to its original value). If you do
not wish to change the IP address on the PC, use a terminal to
connect to the AP and set the IP address. See “Explanation of Top
Menu and IP Settings” in this chapter for details of how to set the IP
address using a terminal.

Supported web browsers (recommended)

- Microsoft Internet Explorer 3.0 or higher

- Netscape Navigator 3.0 or higher

In addition to the above browsers, browsers that support frames
(HTML 2.0) can also be used.

Connecting to the Web Browser PC

When using a web browser to setup the AP, you can connect via
either a LAN or a modem. Use the following procedure to connect
the web browser.

Connecting via a LAN

(1) Connect the PC on which you will run the web browser to the

same network as the AP.
Alternatively, you can use a UTP cable to connect the PC
directly to the AP. In that case, use a crossed-cable.
The connection will not work if you use a standard straight­through cable.

Connecting via a modem

(1) Connect modems to the AP and to the PC on which you will

run the web browser.
Use a COM port to connect the modem.

(2) Connect each modem to a telephone line and establish a

connection from the web browser PC to the modem connected
to the AP.

58

For Windows 95, use the standard dialup network function to
establish the connection.

Windows Setup Screen

- No compression

- Fixed IP address

- No authentication

- No login

Note!

You may not be able to establish a connection if the web browser is
setup to use a proxy. In this case, change the setting to not use a
proxy.
Remember to change the proxy setting back when you have finished
setting up the AP.

FX-DS110-APE

Connecting to an FX-DS110-APE

To connect the web browser to the AP, the IP address of the PC on
which you run the web browser must be in the same network group
as the IP address of the AP. The factory default IP address set in
the AP is always in the class A network group starting with [10]
(that is, 10.xxx.xxx.xxx). Accordingly, set the IP address of the
PC to also start with [10] ([IP 10.1.1.1, MASK 255.0.0.0], for
example). Remember to set the IP address of the PC back to its
previous value after you have finished with the connection for
setting up the AP. When setting up the AP, it is recommended that
you change the IP address of the AP.

(1) Start the web browser

Recommended web browsers are Microsoft Internet Explorer

3.0 or later and Netscape Navigator 3.0 or later.

(2) After starting the web browser, enter the IP address of the AP

in the URL field.
For example, if the IP address of the AP is [10.66.1.1], enter
the following:

AP Setup

AP name

Assigning a name to an AP makes it easier to identify on the
network. Enter a name of up to 16 alphanumeric characters.

Unit type

Select either “AP” or “Station”. “AP” means the AP manages user
units and other APs that are operating as stations. “Station” means
the AP is managed by (logs in to) another AP and is set when the
AP is used as a bridge or similar. The factory default setting is
“AP”.

ESSID of this AP

The name of the wireless LAN to which the AP belongs.
Changing the ESSID causes the AP to be disconnected from the
network. Enter a name up to 32 alphanumeric characters. The
name is case sensitive. The factory default setting is
“LocalGroup”.

66

Access point type

In wireless networks containing multiple APs, setting one of the
APs as the master is helpful for network operation. Select one of
“Master”, “Backup Master ”, or “Normal”. The factory default
setting is “Normal”.

Table 6.2. Access Point Type

Master Manages other APs in the same network. Only one AP can be set as

the master. The main purpose of centralized management is that it
allows the existence and operating status of all APs to be managed
centrally and it facilitates firmware upgrades and IP tunneling.
A master AP is required to use the IP tunneling function.

Backup Master Operates as the backup master if the master does not respond.

Only one AP can be set as the backup master.

Normal Standard AP

FX-DS110-APE

Bridge function

When using the AP in brouter mode or inter-segment brouter mode,
disabling the bridge function causes the AP to operate as a router
rather than as a brouter. Enabling the bridge function causes the
AP to operate as a brouter. The factory default setting is “Enable”.

Preferred APs

Specify the preferred APs to log into. A maximum of 5 APs can
be specified. APs in lower numbered positions have higher
priority. If logging in to other than preferred APs is disabled, the
AP cannot log in to APs not in this list. This setting is only
applicable when enhanced roaming is enabled.

times and at what time interval to retry the transmission. The
factory default settings are 3 retries and a retry interval of 3
seconds.

Master AP recovery check settings

If communication halts due to a fault or other problem on the
master AP, the backup AP takes over as the master. While the
normal APs continue to operate by using the backup AP as the
master, they also check for the existence of the master AP to
determine whether it has recovered. This setting specifies how
many times and at what time interval to perform this check. If a
response is received, the AP resumes operation using the master AP
as the master. The factory default settings are 3 retries and a retry
interval of 3 seconds.

7. AP Maintenance

This chapter describes how to perform maintenance on the AP and
explains the tools to be used. Here, “maintenance” means the
following: log file collection, firmware upgrades, and saving and
restoring the software settings.

Maintenance Tool

Two different maintenance tools are available for the AP:
SmartMedia and the TFTP file transfer utility. This section
describes how to use both tools.

How to Use SmartMedia

The AP uses SmartMedia for the following three purposes

- Save and update (restore) the settings file for the access point

- Log file collection

- Firmware upgrades

When inserting the SmartMedia into the SmartMedia slot, insert
carefully with the orientation shown in the figure on the next page.
When removing the SmartMedia, wait for the busy light to go out,
then press the eject button.

AP Maintenance

Notes!

A 3.5 inch floppy disk adaptor can be purchased separately for
SmartMedia. This is useful for transferring the collected log file
to a PC.

- SmartMedia is sold separately. You can use 3.3V SmartMedia

in the following sizes: 2MB, 4MB, 8MB, 16MB, or 32MB.

- When you insert a SmartMedia into the AP, the AP automatically

reads the SmartMedia if the write-protect seal is attached or
automatically writes to the SmartMedia if the write-protect seal
is not attached. Take care not to insert a SmartMedia
containing important files with the write-protect removed.

- Inserting a SmartMedia charged with static electricity into the

AP may cause malfunction or data corruption in the AP.

Using SmartMedia to Get the Log File

Notes!

- Any existing data on the SmartMedia is overwritten

- When you use SmartMedia to get the log file, the settings file is

also saved.

(1) Gently insert a SmartMedia without a write-protect seal into

the SmartMedia slot on the AP. The eject button moves out
slightly when the SmartMedia is in place.

(2) The AP copies the collected log file and settings file to the

SmartMedia. As the “BUSY” LED illuminates while the AP
is writing to the SmartMedia, do not eject the SmartMedia
during this time. Ejecting the SmartMedia during this time
may damage the drive or corrupt the data.

(3) After the “BUSY” LED goes out, press the eject button and

remove the SmartMedia.

(5) To save the log file, enter the save location in the “Path for

Saving Received File” field.
(6) Click the OK button.
(7) Exit TFTP.

FX-DS110-APE

Saving the Settings File

Making a backup of the AP software settings file has the following
benefits:

- If you have more than one AP and all APs have the same settings,

you just need to setup one AP then use the resulting settings file
for the other APs. (However, as this sets the same IP address for
all APs, you need to change the IP address separately.)

- The old settings can be restored easily if a fault causes the

settings file to be erased.

The settings file contains all the settings described in Chapter 6.

Using SmartMedia

The Ethernet address of the AP is used to generate the settings file
name.

【Example】 If the Ethernet address is (00.08.4C.01.02.03):

00.08.4C.01.02.03
↓
File name = 010203.INI

Note: As this (generally) results in a unique file name, the settings

files for multiple APs can be saved on the same SmartMedia.
The size of each file is approximately 4KB.

Restoring the Software Settings

Using this function has the following benefits:

- If you have more than one AP and all APs have the same settings,

you just need to setup one AP then use the resulting settings file
for the other APs. (However, as this sets the same IP address for
all APs, you need to change the IP address separately.)

- The old settings can be restored easily if a fault causes the

settings file to be erased.

Using SmartMedia to Restore the Settings

(1) Prepare the SmartMedia containing the software settings file.
(2) Place a write-protect seal on the SmartMedia.
(3) Gently insert the SmartMedia into the SmartMedia slot on the

AP.
(4) The AP reads the settings file from the SmartMedia and

updates its settings.

to “Master”

: Set “Automatically Upgrade Firmware from

Master” to “Enabled” on all APs other than the
master.

(1) Use SmartMedia or TFTP to upgrade the firmware and then

reboot the master.
(2) Reboot each of the other upgraded APs either using TFTP or

the reset button on the AP itself. This causes the APs to read

the firmware from the master.
(3) While reading the firmware, all LEDs on the front of the AP

blink. When the LEDs stop blinking, the AP reboots to run

the new firmware.

AP Maintenance

Running the Loader to Forcibly Upgrade the Firmware

(1) Turn off the power to the AP and prepare a terminal

connection (see Chapter 5).
(2) Prepare the AP firmware on the PC you are using as a

terminal.
(3) Set the INIT DIP switch to ON to run the loader.
(4) Connect the terminal. To login, just press the ENTER key at

the password input screen.
(5) Select “6. Download” → “2. Firmware” from the Top menu.

AP Maintenance

(6) Using the Xmodem protocol, send the firmware you prepared

in step 2.

(For example, if you are using HyperTerminal, select “File

Transfer” from the “Transfer” menu, specify the name of the

firmware file you prepared in step 2 and select the Xmodem

protocol, then click the send button.)
(7) Reboot the AP after it finishes reading the firmware.

(Change the INIT switch back to OFF before rebooting.)

Using TFTP to Reboot the AP

(1) Start TFTP.
(2) Select “Send Reset Command to AP”, then click the “OK”

button.
(3) Enter the IP address of the AP in the “IP Address of AP to

Reset” field.
(4) Click the “OK” button, then exit.

Spanning Tree Algorithms (STA)

8. Spanning Tree Algorithms (STA)

This chapter describes spanning tree algorithms (STA's) supported
by this product.

What is an STA?

Communication between nodes on two bridged LAN segments
must take place on one path. If two or more paths exist, packets
may get caught in the loop and the network, unable to eliminate the
packets, may crash. If the network can be configured in such a
way as to eliminate the possibility of network loops this problem
cannot occur, but if spare paths are provided and used, it is
necessary to switch routes manually. The problem can be avoided
if the bridge has the following functions.

Network loop detection and avoidance

This function detects path that are involved in network loops and
keeps only one path active. The other path is kept available for
backup but cannot be used.

Automatic topology reconfiguration

This function reconfigures the network topology when a fault
occurs on a backup route.

Note!

This method of resolving problems is called an STA, and has been
standardized by the spanning tree protocol (STP) established in
IEEE 802.1D. STP can enhance network reliability.

For STA's to function properly, all bridges in a network must
support STP.
