Installation of a driver  
Installation in a network  
This section describes how to install the FLEXLAN-DS110 series  
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  
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:  
- Signal attenuation  
- Signal interference  
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 wall  
FX-DS110-PCC  
15  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Installation of a driver  
Obstacles blocking radio waves include metal walls and walls  
containing a metal firewall.  
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.  
Note!  
Pay attention to radio interference.  
Radio interference with this product indicates any disturbance to  
reception, caused by that radio wave in the frequency band of this  
product which is generated outside the local network. Listed  
below are major examples of sources of interfering radio waves  
generated in general environments excluding plants and factories:  
- 2.4 GHz band wireless network  
- Other sources  
-
-
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.  
Radio interference by a wireless network can be removed by  
changing the channel used. Note, also, that dividing the same  
network into groups different in channel may increase the data rate.

Installation of a driver  
Constructing a network  
Given below are the guidelines and notes on constructing a network:  
(1) The operating distance of the FX-DS110-PCC between the AP  
and user unit is about 150 m in indoor space with no obstacle  
or about 50 m in indoor space with few obstacles.  
(2) This product enables communication via a total of 11(FCC  
model) or 13(CE model) channels from channels 1 to 11 or 13.  
Channels selected at intervals of five consecutive channels can  
be used for communication without mutual radio interference  
(except channel 11). When more than one channel is used,  
radio waves can be utilized most efficiently using channels 1, 6,  
and 11.  
(3) The operation mode and software settings such as ESS ID must  
be selected depending on the operation form. (See Chapter 5.)  
(4) The operating range for communication with another terminal  
is about 50 m in indoor space free of radio wave attenuation  
caused by an obstacle or radio interference, covering almost  
the entire area of small- and medium-scale offices and plants.  
Note, however, that extending the communication distance  
beyond a certain degree increases the number of transmission  
and reception errors.  
(5) When installing the PC Card, use the FLEXLAN-DS110 utility  
to check the RSSI value. In general, a remote party’s RSSI  
value of 70 or more assures stable communication. Even  
when the RSSI value is 70 or more, however, communication  
may not be stable, due to multipath for example, depending on  
the operating environment. Communication cannot be  
performed normally when the RSSI value is 50 or less.  
After checking the RSSI value, run some applications that you  
usually use to check whether actual communication can be  
performed. In the TCP/I environment, for example, you can  
use PING in Windows. To ping, invoke the MS-DOS prompt  
and enter the PING command as shown below. In this  
example, the IP address of the target AP is 10.168.132.15.  
C:\>ping 10.168.132.15  
(6) Wireless terminals placed near to each other may fail to  
communicate with each other because of mutual interference.  
Allow a minimum spacing of 1 m between user units and that  
FX-DS110-PCC

Installation of a driver  
of 3 m between each AP and user unit.  
(7) When this product is used in the ADHOC (Simple) Mode,  
network performance is degraded unless all the terminals exist  
within the operating range for communication. (See "Hidden  
Terminal Problem” in Chapter 7.)  
Operation of the FLEXLAN-DS110  
This section describes the types of networks configurable with the  
FX-DS110-PCC, using basic examples. This product has two  
operation modes: ADHOC (Simple) Mode and Infrastructure  
(Standard/Brouter) Mode for different network models. To  
construct a network with the FX-DS110-PCC only, use it in the  
ADHOC (Simple) Moe. When the FX-DS110-APE, the AP  
(access point) in the FLEXLAN-DS110 series, is used with the  
FX-DS110-PCC, use it in the Infrastructure (Standard/Brouter)  
Mode.  
Infrastructure (Standard , Brouter) Mode  
In this mode, communication is performed always via the AP. The  
AP has features (100BASE-TX and 10BASE-T) for connection to  
Ethernet, enabling connection between the wireless and wired  
networks. The AP has advanced features such as routing and  
roaming and allows you to perform all setup and management  
easily from within the web browser over the LAN. As the AP has  
the SNMP agent feature, network management software such as an  
option of “SNMPc” can be used for management.

ADHOC (Simple) Mode  
In this mode, all wireless terminals communicate with one another  
on a par basis. Since wireless terminals communicate directly  
with each other, the most part of setup at installation is not required  
and faster communication can be expected than in the AP-  
centralized configuration. When installing the terminals, place  
them all within their operating distance for communication (to  
prevent the hidden terminal problem). In the following example,  
the terminals can be connected to Ethernet via the AP (operating in  
simple mode). Although the network can be constructed only with  
the FX-DS110-PCC, no terminal can be connected to Ethernet in  
that case.

RSSI indicating the signal strength of a radio station  
RSSI is data used when the FX-DS110-PCC is installed, indicating  
the strength of the radio signal being received. The RSSI value of  
each radio station is displayed in association with the MAC address  
or the terminal name if assigned. Note that RSSI values are  
displayed only for terminals having the same ESS ID.  
The “RF Signal Strength” table lists only the APs (excluding those  
serving as stations) when this product is operating in the  
Infrastructure (Standard/Brouter) Mode. When the product is  
operating in the ADHOC (Simple) Mode, the table lists both of APs  
and user units.  
RSSI is displayed in a bar chart. In the bar, the blue, yellow,  
yellowish green, and cyan portions indicate the terminals whose  
RSSI value is 0-50, 50-70, 70-100, and 100-150, respectively.  
This product should be placed for an RSSI value of 70 to obtain  
stable communication quality. When the RSSI value is 50 or  
less, it is highly possible that communication is disabled.

Using and Setting up the Utility Software  
Editing the name of a radio station  
The FLEXLAN-DS series utility displays each wireless terminal  
using the MAC address when the radio station name has not been  
edited. Once the MAC address is assigned a name by the radio  
station name edit function, the wireless terminal is displayed with  
that name, making it easy to identify the terminal.  
To register a new wireless terminal, click on the “Add” button, enter  
or select the MAC address of the terminal, then enter the name.  
The name can be up to 22 single-byte characters or 11 double-byte  
characters long. It accepts kanji characters.  
The terminal registration information (the combination of the MAC  
address and name) can be filed, saving the time and labor for  
registration. To read registration information from a file, click on  
the “Import” button. To file registration information, click on the  
“Export” button.  
Once registration information has been saved, it stays retained even  
after the FLEXLAN-DS series utility has been terminated. Up to  
100 sets of MAC address and name can be registered.

product and what to do about them. If any problems occur that are  
not described here, check to confirm that the re-occur, then contact  
the store where you purchased the product, or the CONTEC  
information center.  
Cannot detect the LAN card automatically  
When this product is plugged for the first time, Windows 95 or  
Windows 98 usually detects it automatically as a new piece of  
hardware. In some cases, however, the product may not be  
detected automatically for some reason.  
Already registered as one of <Other devices>

devices]. If it is, delete the entry according to “Uninstallation of  
hardware” in Chapter 4 and install the driver over again.  
Possible causes are as follows:  
- Windows 95 or Windows 98 was installed with this product  
already plugged.  
Do not plug the PC Card before installing the OS.  
- This state may be caused by aborting the installation process by  
clicking the “Cancel” button prematurely.

Troubleshooting  
When Communication Fails  
Check this section if communication is disabled while the driver has  
been installed normally.  
Check hardware  
- Check if the antenna is loose or if there is any shielding object  
covering the antenna.  
- Check whether the PC Card has been plugged deep into the PC  
Card slot.  
Check software  
- Check whether the operation mode has been set correctly. For  
communication with the AP, also check its settings. To use the  
user unit in the ADHOC (Simple) Mode, place the AP in the  
simple mode. To use the user unit in the Infrastructure  
(Standard/Brouter) Mode, place the AP in any mode other than  
the simple mode.  
- Check whether the ESS ID is the same as that of the recipient.  
- Check whether the data encryption setting is the same as that of  
the recipient.  
- Check whether the driver has been installed normally. Check  
the properties of the “CONTEC FX-DS110-PCC” under Network  
Adapters in Device Manager.  
- Check whether the channel being used matches that of the  
recipient.  
Check the peripheral environment and place of installation  
- A nearby source of electromagnetic interference can prevent  
communication. In general locations (excluding factories) the  
following may be sources of electromagnetic emissions.  
- Another wireless network using the 2.4 GHz band  
- Microwave ovens  
- Security gates  
- Copiers  
- Elevator motors  
Most electromagnetic sources other than wireless networks are  
local and not continuous, and therefore by moving the location of  
the unit (the PC containing this product or the recipient) and  
waiting briefly, communication may be possible.

Troubleshooting  
Interference caused by a wireless network can be avoided by  
changing the channel used. Note, also, that dividing the  
terminals in the same network into groups different in channel  
may improve the data rate.  
- Sometimes communication is hindered by attenuation of electric  
waves. Attenuation occurs naturally as distance from the source  
of transmission increases, but may also be caused by objects in  
the path of the transmission. The objects primarily responsible  
for attenuation are the following.  
- Concrete walls  
- Metallic surfaces around antennas

Glossary  
IEEE (Institute of Electrical and Electronics Engineers)  
"I-triple-E," involved in a wide range of fields from  
communications and computer to medicine and biology, with  
primary activities related to publishing articles and sponsoring  
conferences, but also recommending and setting of standards. The  
organization sponsoring Committee 802, which is responsible for  
LAN related matters.  
SNMP (Simple Network Management Protocol)  
A function necessary for network control, provides three functions:  
Get (acquire), Set (modify), and Trap (notify event). Conceived as  
an easily installable control protocol that places as little load on the  
network as possible.  
LAN (Local Area Network)  
A network configured from mutual connections between computers  
within a limited area. Also called an "intranet" or "business or  
regional data communications network."  
Peer-To-Peer  
A network in which two or more nodes can communicate directly  
with each other without going through another device.  
AP (ACCESS POINT)  
Access point. In the FLEXLAN-DS110 series, the access point is  
used as a bridge between wired and wireless networks and provides  
advanced features such as the inter-segment brouter function and IP  
tunneling, serving as an indispensable component for a versatile and  
large-scale wireless network.

Appendix  
Roaming  
This means the same as roaming of a mobile telephone or PHS.  
The AP serves as the component commonly called as “antenna/base  
station” in mobile telephone and PHS terminology; the  
FX-DS110-PCC serves as the telephone itself.  
IP tunneling  
One of the features of the FX-DS110-APE. Using this feature enables  
mail transmission and reception and database access without changing  
the PC settings even at a roaming destination beyond the router.  
Spectrum diffusion transmission  
A method of transmission in which signals that are normally  
transmitted over a given limited frequency band undergo narrow  
band modulation (primary modulation), then again diffuse  
modulation (secondary modulation) to intentionally diffuse the  
signal over a broad frequency spectrum.  
DS (Direct Sequence)  
A type of spectrum diffusion signal using narrow band modulation  
with phase modulation, in which the diffusion is by means of phase  
modulation using a broad band diffusion signal (pseudo random  
strings).  
CSMA/CA (Carrier Sense Multiple Access with Collision  
Avoidance)  
CSMA is a method of avoiding collision by which wireless  
terminals listen before transmitting and do not transmit if they can  
year transmissions from other wireless terminals. CSMA/CA is  
CSMA plus additional collision avoidance functions.  
Hidden Terminal Problem  
When wireless terminals are farther apart then their electric signals  
can reach, or their signals are obstructed by objects, neither may be  
able to receive the other's signals. Any two such wireless  
terminals are said to be hidden from each other. In Ad Hoc mode,  
because the carrier sense function is not effective between hidden  
terminals there is a higher probability of collisions and throughput  
(the volume of information sent in a given time interval) is reduced.

RTS (Request To Send)  
In communication via AP, transmission is controlled by CSMA/CA  
plus RTS. In RTS, a wireless terminal asks the AP if it is all right  
to transmit, and only transmits after an OK-to-send  
acknowledgement signal is returned. This serves to avoid  
unnecessary collisions when hidden terminals exist because hidden  
terminals cannot transmit.  
RSSI (Receive Signal Strength Indication)  
A numeric indicator of incoming signal strength.  
ESS ID (Extended Service Set ID)  
In the FLEXLAN DS110 series, the ESS ID is like a name assigned  
to the wireless LAN network to which a unit belongs. The same  
name must not be given to more than one wireless terminal.  
Conversely, a wireless network can be partitioned by using different  
ESS ID names.  
Channel  
This term has the same meaning as a television or radio channel.  
In the ISM band used by this product, the IEEE 802.11 standard  
provides for division into 11(FCC model) or 13(CE model).  
channels numbered 1 to 11 or 13. Even on the same network,  
wireless devices operating on different channels cannot  
communicate with each other.  
Multipath  
Multiple versions of a radio wave emitted to be used for  
communication, which are received after being reflected by  
buildings and walls. Some of them are received after being  
reflected several times repeatedly. A strong multipath effect  
results in distortion of the signal in the directly received radio wave,  
degrading the communication quality and disabling stable  
communication
