Overview FX-DS110-APL 8 DIP Switches The DIP switches are used to make AP settings. The default setting for the utility software gives priority to the DIP switch settings. The factory setting for all DIP switches is OFF. At the factory, the unit is set to Ad Hoc Mode. The unit can be used with the factory settings, by setting only the DIP switches. However, security is not assured. Table 2.5. DIP Switches Used to initialize APs.When this switch is turned on, the POWER, WLNK, and WRX LED will start flashing.If this switch is turned off while the LED's are flashing (about 3 seconds, then all AP settings will be restored to default values after the next startup.)If this switch is on, the AP can operate without an IP address.However the utility software cannot use the SNMP agent functions.This switch sets the unit type.It is valid when operating in infrastructure (standard mode).AP… Controls APs used on other user units or STs.ST… Treated as a user unit (controlled by (logged in) AP).This switch sets the mode.INFRA… Selects infrastructure (standard mode).All wireless terminals communicate through unit type AP.ADHOC… Selects ADHOC (simple mode).All terminal are paired, communicate only as paired units.All switches are set to OFF at factory.OFFADHOCDescriptionON43AP2IPLESS _ST_INIT1INFRA
Overview FX-DS110-APL 9 Multi-channel Operation By changing channels on adjacent access points, it is possible to obtain higher throughput per wireless terminal than when is channels are not changed, even when the number of wireless terminals is increased. The 2.4G band (2400 to 2483.5 MHz) in which this product operates is subdivided into 13 channels, numbered 1 to 13, by IEEE standard 802.11. Because each frequency has sidebands around its central frequency, sidebands on adjacent channels overlap. Overlapping frequencies can adversely affect communications by interference with each other's transmissions. Refer to Figure 2.3 when selecting channels, to ensure that frequency bands do not overlap. The maximum number of channels that can be used simultaneously without interference is four, by using a combination of channels 1, 6, and 11. Channel numbers can be set from 1 to 13 using utility software. Two wireless terminals on the same network cannot use the same frequency.

Operating Mode Descriptions FX-DS110-APL 12 3. Operating Mode Descriptions ADHOC (Simple Mode) The following example shows a relatively small network configured using ADHOC mode. AH1AH3AH2AH4FSNetwork ANetwork BPOWERWRXWLINKLINKRXAH : Devices in ADHOC connectionFS : File server : Wireless connectionPOWERWRXWLINKLINKRXPOWERWRXWLINKLINKRXPOWERWRXWLINKLINKRX Figure 3.1. ADHOC Mode In ADHOC (simple mode), all wireless devices are paired, and can use wireless communication with the other device in the pair. Lines can be duplicated using a spanning tree if bridges are 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 mode. (2) Not suited to construction of large wireless LAN environments. Note! 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.
Operating Mode Descriptions FX-DS110-APL 13 Infrastructure (Standard Mode) 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.

Spanning Tree Algorithms (STA) FX-DS110-APL 38 6. 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. 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. Note! For STA's to function properly, all bridges in a network must support STP.
Spanning Tree Algorithms (STA) FX-DS110-APL 39 STA Parameters STA's function on two levels, bridge level and port level. Multiple timers are used to periodically check the proper operation of bridges and ports. The following section describes the parameters and terms used in this product. Bridge Level Root Bridge First, the bridge is determined using the bridge identifier (bridge priority level and Ethernet address) of the bridge. The bridge identifier of the root bridge is the smallest. If more than one bridge exists with the same priority level, the root bridge is determined by Ethernet address. Designated Bridges In each LAN segment, the bridge having the lowest root path cost to the root bridge is the designated bridge. The designated bridge serves to carry the packages of that LAN segment. If more than one bridge is connected to the same LAN segment, and the root path costs are exactly the same, the bridge with the smallest bridge identifier becomes the designated bridge. Bridge Priority The priority level can be set in the range 0 to 65535. The smaller this number, the higher the priority. If priorities are changed, all bridges and root bridges in the network will be re-determined. Root Path Cost The total path cost from the designated bridge to the root bridge is the root path cost. The root path cost of the root bridge is zero. BPDU Effective Time (Max Age Time) Set in the range from 6 to 40 (seconds). If the bridge does not receive a packet notifying the existence of a root bridge within this time, the system assumes there is a failure in the root bridge, and determines a new root bridge.
Spanning Tree Algorithms (STA) FX-DS110-APL 40 BPDU Send Interval (Hello Time) Set in the range from 1 to 10 (seconds). This determines the interval within which a bridge that is the root bridge sends a packet notifying its existence. This parameter may not exceed the Max Age Time. Forward Delay Time Set in the range 4 to 30 (seconds). When the ports of a bridge change from blocking to forwarding status, this determines the time in which they will remain in listening status. Note! The following conditions must be observed when making changes to the above time settings. Max Age Time ≦ 2 x(Forward Delay Time – 1)Max Age Time ≧ 2 x(Hello Time + 1)
Spanning Tree Algorithms (STA) FX-DS110-APL 41 Port Level Root Port On each bridge, the port having the lowest path cost to the root bridge is called the root port. If more than one port has the same path cost, the port with the smallest port identifier (port priority and assigned port ID) is the root port. Designated Port The port on the designated bridge connected to the LAN segment is called the designated port. On the bridge, packages are only transferred on the port that is the root port, and other ports are blocked. Port Priority Set in the range 0 to 255. The lower the number, the higher the priority level. Path Cost The port cost on a path is called the path cost, and is set as follows when this product is initialized. This value is based on IEEE standard 802.1D, but can be changed. ･ 10Mbps LAN segment 100

Troubleshooting FX-DS110-APL 50 8. Troubleshooting This chapter describes common problems that may occur with this 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. When Communication Fails Check hardware ･ Check that the LAN cables are connected correctly. Check software ･ The FLEXLAN-DS110 series is designed to handle a variety of operating formats, and requires software setting for each type of operation. Check that the settings are appropriate for the type of operation, and check the format in which communication is being attempted. Also check DIP switch settings. ･ The terminals that cannot communicate with each other may have the same ESS ID. Two terminals with the same ESS ID cannot communicate with each other. ･ Check that the APL IP address and subnet settings have been entered. ･ Check that the operating mode setting has been correctly entered. ･ Check whether communication is restricted by security functions. ･ Check whether the data encryption setting is the same as that of the recipient. ･ Check that the channel setting has been correctly entered. ･ Check that the communication speed setting has been correctly entered.
Troubleshooting FX-DS110-APL 51 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. ･ 2.4GHz band wireless networks not compatible with IEEE 802.11b. ･ 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 and waiting briefly, communication may be possible. Also, do not place wireless devices too close together. A distance of at least 1m should be allowed. ･ 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 Stable transmission at 11Mbps requires an RSSI value of at least 80. The RSSI value can be verified on the Wireless Device Information tab on the Status screen using the utility software. When SNMP Connections Fail ･ It is possible that the device cannot locate a control parameter, or that a private MIB has not been compiled. See Chapter 6. ･ If MIB settings have not been made, the correct community name may not have been entered. Be sure the community name setting agrees with the network manager's setting. ･ Check the SNMP settings that are being used.
Troubleshooting FX-DS110-APL 52 When the APL Will Not Start Check the power LED ･ Be sure the power LED is on. If it is not on, check the AC adapter, be sure it is correctly plugged into an outlet, and that the power supply type agrees with the power supply switch setting. ･ Check whether the power LED is flashing. If the power LED is still flashing more than 10 minutes after the power is switched on, the problem may be an APL firmware failure. Use the utility software to upgrade the firmware version.

Appendix FX-DS110-APL 57 Glossary IEEE (Institute of Electrical 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. IEEE 802.11/ IEEE 802.11b The wireless LAN standard established by the IEEE. MIB (Management Information Base) The value of a MIB is determined by the Internet standard control information structure. 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. Diversity A method of using multiple antennas, and selecting the one with the best receiving conditions. Router A device for relaying between LAN's. The router determines data addresses by the combination of a network address assigned to the network and an individual computer address. Used particularly in medium-scale and larter LAN systems with very large number of clients, to reduce traffic (congestion) on communication lines. Bridge A device for relaying between LAN's. The bridge determines whether to relay data based on the address of the computer to which the data is being sent. It can be used to connect networks having different protocols, or when data for broadcast to all computers is received, can send this to all connected networks.
Appendix FX-DS110-APL 58 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." RSSI (Receive Signal Strength Indication) A numeric indicator of incoming signal strength. 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.
Appendix FX-DS110-APL 59 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. Roaming This term has the same meaning as roaming for a portable phone or PHS. The AP is in the role commonly called the 'antenna/base station' for the phone or PHS, and the user unit is in the role of the phone itself. 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) In the FLEXLAN-DS110 series, access points serve as the bridge between wired networks and wireless networks, as well as providing bridge functions between segments and IP tunnel functions indispensable to the building of versatile, large-scale networks. User Unit In the FLEXLAN-DS110 series, this refers to the FX-DS110-PCC or a device with the FX-DS110-PCC built in. 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 2.400 to 2.497GHz band used by this product, the IEEE 802.11 standard provides for division into 14 channels numbered 1 to 14. Even on the same network, wireless devices operating on different channels cannot communicate with each other.
