2. Functions and Wireless Link Mode
2. Functions and Wireless Link Mode
This chapter describes the major functions of the FLEXLAN DS540 series as a wireless LAN system and
the wireless link modes of the FX-D540-APDL along with configuration examples of networks available
in the wireless link modes.
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 w ireless link mode of a FLEXLAN-DS540 user unit is “Standard Infrastructure” or “Compatible
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 UU1 moves and therefore the connection to the wired LAN is lost when UU1 is in position (2).

IP Tunneling Function
(To be supported in the near future)
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 UU1, which belongs to network group A, can connect via a
router to terminal PC1, also in network group A, despite UU1 being connected to the LAN via AP2
which belongs to network group B.

MAC Address Filtering
MAC address filtering is the function to permit only the user units whose MAC address has been
registered for an AP to log in to the AP. Using this function can reject an attempt to log in to an AP by
an unidentified user unit not registered in the AP.
Figure 2.4 shows a sample image of connections under control of MAC address filtering. The example
assumes that the MAC addresses of UU1 and UU2 are registered in the MAC address filtering list for the
AP while UU3’s MAC address is not registered in the list. In this case, UU1 and UU2 can log in to the
AP but UU3 cannot. To permit UU3 to log in to the AP, the AP ’s administrator has to add the UU3’s
MAC address to the MAC address filtering list for that AP.

Bridge Packet Control
Bridge packet control is the function that allows an AP to pass only data from those network devices
whose MAC address has been registered for the AP to its clients. Using this function can restrict
communication between user units.
Figure 2.5 shows a sample image of connecting under bridge packet control. The example assumes that,
for bridge packet control, only the MAC address of the router is registered in AP1 and AP2. In this case,
UU1, UU2, and UU3 can exchange data with the external network through the router while they cannot
communicate with one another. When the router is connected to the Internet, UU1, UU2, and UU3 can
access the Internet while they cannot communicate directly with each other.

If the bridge packet control list for the AP contains no entry with the bridge packet control function enabled,
communication is unconditionally permitted between a wired unit and a wireless unit but rejected between
wireless units.
When the bridge packet control list for AP1 and AP2 contains no entry in the above example, UU2 and
UU3 can communicate with each other via AP1 and AP2 while UU1 and UU2 cannot.

2. Functions and Wireless Link Mode
Wireless Link Mode Descriptions
The AP has three wireless link modes. The available functions and network configurations differ
depending on the mode. Use the wireless link mode most suitable to the type of network you are
constructing. The factory default setting is simple mode. Chapters 4 and 5 describe the software setting
procedures for the wireless link modes and related items.
Standard Infrastructure Mode
In this mode, each access point (AP) can accommodate user units (stations) to make up a network.
This mode allows the use of multiple AP's to configure wide -area wireless LAN's. All communication
between wireless terminals must go through an AP.

Figure 2.7. Standard Infrastructure Mode
In the above standard infrastructure 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 5).
- Advantages
(1) Capable of accommodating APs as stations.
(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).
(4) Capable of improving security based on WSL (Wireless Security Link)
2. Functions and Wireless Link Mode
Compatible Infrastructure Mode
This mode allows the FX-DS540-APW to be networked with other manufacturers’ Wi-Fi certified
wireless terminals other than the CONTEC ’s FLEXLAN series. Communications between the wireless
terminals are always made via the APs.
CAUTION
The Compatible Infrastructure mode does not guarantee interconnection with Wi -Fi compliant
products of other manufacturers.

Figure 2.8. Compatible Infrastructure Mode
In the Compatible Infrastructure mode, each wireless terminal performs communication via the AP as in
the Standard Infrastructure mode. As the roaming function is supported, the wireless terminal can log in
to any unit type AP within the coverage.
The unit type AP does not provide FX-DS540-APDL’s unique features as it works as a simple bridge.

The terminal set to the Standard Infrastructure mode can use the FX-DS540-APDL’s unique features.
The terminal set to th e Compatible Infrastructure mode serves as a simple bridge and thus cannot use the
FX-DS540-APDL’s unique features.

Wireless Link Mode and Communications
The table below shows which wireless terminals can communicate with each other depending on the
operating mode of the AP and user unit.
[Table notation and notes]
1. UU stands for “ user unit ”.
2. AP⇔UU indicates communications between a unit type AP and user unit.
3. ST indicates an “AP managed by (logged in to) another AP” which operates in the same way as a
user unit. See Chapter 5 for details of the setup procedure.

Roaming
The roaming function which allows mobile user units to switch log-in between multiple APs can only be
used. 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.
It can be used in the Advanced Infrastructure and Standard Infrastructure modes.
Station AP connection
A station (unit type ST) indicates an AP managed (logged in) by another AP; it is used to serve as a
bridge.
SNMP
This function enables remote management by software that supports SNMP. Available in all modes.
Log collection function
This function lists the wireless terminals logged in to the AP and collects times and other event
information. See Chapter 6 for details.
2. Functions and Wireless Link Mode
MAC address filtering
This function enables connection of only the terminals whose MAC address has been registered.
Bridge Packet Control
This function allows the AP to pass only that data to terminals which comes from network devices
having a registered MAC address. Communication between wireless terminals can be rejected when
their MAC addresses are unregistered.
Data encryption
This function encrypts wireless data. For encryption, three security protocols are available: WSL
(Wireless Security Link: proprietary cryptography), WEP (Wired Equivalent Privacy ) and AES. WSL
and WEP or WSL and AES can be used at the same time. Note, however, that devi ces using WSL and
those not using it cannot communication with each other.
IEEE802.1X(EAP-TLS)
This function performs authentication using digital certificates. After authentication, the AP
dynamically broadcasts the WEP key.
The function of IEEE802.1X cannot be used when the unit type of the AP is “ station”.
