Chapter One INTRODUCTION The WI-MOD-E Industrial Wi-Fi Wireless Ethernet module provides wireless connections between Ethernet devices or Ethernet wired networks (LAN’s). It complies with the IEEE 802.11b standard. The WI-MOD-E has an internal 2.4GHz direct sequence spread spectrum (DSSS) wireless transceiver, which can be used without a radio license in most countries. Users can select one of 11 5MHz wide channels, with the first channel centered at 2.412 GHz.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual Access Point vs Client The Access Point unit acts as the “wireless master” unit. The Access Point sets up the wireless links to the Client units, and controls the wireless communications. The first diagram shows two Ethernet devices being linked. One WI-MOD-E is configured as an Access Point and one as a Client - in this example it doesn’t mater which unit is the Access Point.
Bridge vs Router Each WI-MOD-E is configured with an IP address for the Ethernet side, and another for the wireless side. A Bridge connects devices within the same Ethernet network - for example, extending an existing Ethernet LAN. For a Bridge, the IP address for the wireless side is the same as the Ethernet side. A Router connects devices on different LAN’s. The IP addresses for the Ethernet and wireless sides are different.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 1.2 User Manual Getting Started Quickly Most applications for the WI-MOD-E require little configuration. The WI-MOD-E has many sophisticated features, however if you don’t require these features, this section will allow you to configure the units quickly. First, read Section 2, “Installation”. The WI-MOD-E requires an antenna and a power supply.
Chapter Two 2.1 INSTALLATION General The WI-MOD-E module is housed in a rugged aluminium case, suitable for DIN-rail mounting. Terminals will accept wires up to 2.5 sqmm (12 gauge) in size. Module is mounted using the spring loaded DIN Rail mounts located on the back of the module. To mount, clip the top of the DIN Rail clip on to the DIN rail and then press the module back firmly until it clicks into place. To release firmly pull the bottom of the module toward you.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual tolerated for shorter distances. For short distances, it is possible to mount the antennas inside buildings. An obstructed path requires testing to determine if the path will be reliable - refer the section 6 of this manual. Where it is not possible to achieve reliable communications between two WI-MOD-E modules, then a third WI-MOD-E module may be used to receive the message and re-transmit it. This module is referred to as a repeater.
The gains and losses of typical antennas are Antenna Gain (dBi) Dipole 2 Collinear 5 or 8 Directional 10 - 28 Cable type Loss (dB per 10 m / 30 ft) RG58 Cellfoil -6 RG213 -5 LDF4-50 -1.5 The net gain of the antenna/cable configuration is determined by adding the antenna gain and the cable loss. For example, a 5dBi antenna with 10 meters of Cellfoil has a net gain of -1 dB (5dB – 6dB).

2.3 Power Supply The WI-MOD-E module can be powered from a 9 - 30VDC power supply. The power supply should be rated at 1 Amp. The positive side of the supply must not be connected to earth. The supply negative is connected to the unit case internally. The DC supply may be a floating supply or negatively grounded. The power requirements of the WIMOD-E unit is 240mA @ 12V or 150mA @ 24VDC. This is inclusive of radio and Ethernet ports active, & serial port plugged in.

WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 2.5 User Manual Discrete (Digital) Input/Output The WI-MOD-E has one on-board discrete/digital I/O channel. This channel can act as either a discrete input or discrete output. It can be monitored, or set remotely, or alternatively used to output a communications alarm status. If used as an “input”, the I/O channel is suitable for voltage free contacts (such as mechanical switches) or NPN transistor devices (such as electronic proximity switches).
Chapter Three OPERATION 3.1 Start-up “Access Point” Start-up An Access Point (AP) unit starts and immediately begins transmitting periodic messages, called beacons, on the configured channel. Beacons include capability information that a Client may examine in order to identify if the Access Point is suitable for link establishment. Clients will only attempt to establish a link with an Access Point whose beacon indicates a matching SSID. Access Points do not initiate link establishment.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual link is dropped. Whenever a Client is not connected to an AP, it will cyclically scan all available channels for a suitable AP. Roaming Clients may also roam between Access Points. If a Client receives a beacon from an AP with a stronger signal than the current AP (providing SSID is the same and capability information are compatible), it may disconnect from the first AP and establish a link with the second AP.
3.2 Selecting a Channel The WI-MOD-E conforms to the IEEE 802.11 Wireless LAN specification. The WI-MOD-E supports 11 radio channels, each 5MHz wide, in the range 2412MHz to 2462MHz. Only one of these channels is used for a connection. The desired channel is selected and configured at the Access Point, and is then used for all beacon transmissions and connections. Clients scan all 11 channels for a suitable Access Point and then adopt the same channel as the AP when a connection is established.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 3.3 User Manual Default Configuration The default factory configuration of the WI-MOD-E is • Client/Bridge/ • IP address192.168.0.1XX, where XX is the last two digits of the serial number (the default IP address is shown on the printed label on the back of the module) • Subnet mask 255.255.255.
• Power up the WI-MOD-E module. • Open “Network Settings” on your PC under Control Panel. The following description is for Windows XP - earlier Windows operating systems have similar settings. • Open “Properties” of Local Area Connection. • Select Internet Protocol (TCP/IP) and click on Properties.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual • On the General tab enter IP address 192.168.0.1, Subnet mask 255.255.255.0, and default gateway 192.168.0.1. • Open Internet Explorer and ensure that settings will allow you to connect to the IP address selected. If the PC uses a proxy server, ensure that Internet Explorer will bypass the Proxy Server for local addresses.
3.4.2 Set WI-MOD-E to same network as PC This is the alternate procedure to setting an IP address in the WI-MOD-E. Consult your network administrator for an IP address on your network, the gateway IP address, and network mask. a) Switch Factory Default dip-switch on WI-MOD-E to SETUP position. b) Connect the RS232 port on the WI-MOD-E to the RS232 port on the PC using a “straightthrough” serial cable.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual e) Check values for Boot Address, Boot Netmask, and Boot Gateway. These values should be setto reflect those of the PC you are using to configure the unit. If these are correct skip to step (h). You may check settings again with the rct command. For further help, type the help command. f) Set Boot Netmask to the same settings as the computer you have the Ethernet cable connected to.
the command: bip i) Switch dip-switch on WI-MOD-E to RUN position. j) Type the command reset, or cycle power to the unit. The WI-MOD-E will reset and start with the network settings you have entered. k) Open Internet Explorer and ensure that settings will allow you to connect to the IP address selected. If the PC uses a proxy server, ensure that Internet Explorer will bypass the Proxy Server for local addresses.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual Network Settings Webpage Fields Operating Mode Used to select Access Point (Infrastructure), Client (Infrastructure), IBSS (Ad-Hoc), or MONITOR mode. By default this is set to Client. Device Mode Used to select Bridge or Router mode. By default this is set to Bridge. FTP Enabled This enables access to volatile memory storage on the WI-MOD-E. By default this is disabled.
Radio Encryption Select “None”, “WEP (64-bit)”, “WEP (128-bit)”, “WPA-PSK (TKIP)”, or “WPA-PSK (AES)” security encryption of the wireless data. The default setting is “None”. Encryption Keys 1 to 4 These are the keys used to encrypt radio data to protect data from unwanted eavesdroppers when WEP Encryption is selected. These keys should be the same for all WI-MOD-E units in the same system.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 3.7 User Manual Normal Operation After addresses are configured, the units are ready for operation. Refer to section 1 for an explanation on the operation of a Bridge and Router. Transparent Bridge Operation Bridges are typically used to connect sections of the same IP network together. By default, the WI-MOD-E is configured as a transparent bridge.
E client/station uses 3-address mode any Access Point that it is to communicate with may be configured for either 3 or 4 address mode (i.e. Access Point mode does not matter). 4-address mode allows a WI-MOD-E client/station to bridge traffic from devices connected to its wired Ethernet port without acting as a proxy for their MAC address. This means that a WI-MOD-E client/station in 4-address mode can bridge any Ethernet traffic – not just IP based traffic as with 3address mode.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual Power Level The RF power level is shown in this field. This value is read only and cannot be altered. Data Rate The radio baud rate in Mega (million) bits per second (Mbps) for point to point radio transmissions. The default value is Auto. Basic Rate The radio baud rate in Mega (million) bits per second (Mbps) for multicast messages and management frames. These frames include beacons, authentication, association, etc.
3.9 Spanning Tree Algorithm / Redundancy The bridge “Spanning Tree Protocol” function was introduced to handle network loops and provide redundant paths in networks. To enable the STP requires that WDS mode also be enabled on the “Repeaters” configuration page. When enabling WDS mode on a client/station you should ensure that WDS mode is also enabled at the corresponding Access Point – refer section 3.10 for more information. For example, consider this network with a redundant wireless link.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 3.10 User Manual Multiple AP Repeater Mesh Network The range of a wireless network can be extended by allowing Access Points to behave as repeaters and forward traffic to other Access Points. Access Point to Access Point communications is also known as Wireless Distribution System (WDS). The WI-MOD-E offers very powerful WDS configuration, allowing for a mesh network with self-healing and automatic node discovery.
(i.e. auto connect) network with encryption, the same encryption algorithm and keys must be inherited from the default interface. Note that when WPA is required with a mesh network, the same SSID must be used for each Access Point. Alternatively the list of possible allowed Access Points (by SSID) and their corresponding passphrases must be specified - since WPA Pre-Shared Keys are derived from both passphrase and SSID.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual The WDS configuration for unit B is shown above (this page is accessible via the Repeaters link from the configuration web pages). WDS mode has been enabled, and “Only connect to APs in list” has been selected so that the repeater path is fixed. Since this example is a bridged network (i.e. all devices on the same IP network) and there is no possibility of loops (i.e.
An example of using WDS router interfaces to achieve a similar physical topology to the WDS bridge example discussed earlier is illustrated below. In both examples, there are four WDS Access points each with the possibility of having their own client/stations associated. In both examples A, B, C, and D can all exchange data with each other. The bridged example has the advantage of redundancy but at the expense of extra overhead.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual establish a link – but the MAC address is always broadcast in beacons whereas the SSID broadcast is configurable). Unit B in the WDS router example above has three WDS links – to units A, C, and D; we show unit B’s configuration below. It can be seen that there are 3 entries in the WDS Connections list.
The routing rules for unit B are shown below (for more information on routing rules, refer to the section “3.11 Routing Rules”). The second WDS entry above specifies the WDS link to unit C as a WDS router interface with IP address 169.254.5.3. As with the WDS link to unit A, we use a different IP network address than the default interface (note that this network address 169.254.5.x is also different to that used for the WDS link to unit A 169.254.0.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual WDS Configuration The WDS Configuration page (as seen above) is accessible from the “Repeaters” link on any of the configuration web pages. The configurable WDS parameters are summarized below. Layer 3 bridge When WDS communications are not required, select this option (see section “3.7 Normal Operation” for details on Layer 3 bridge). WDS Select WDS to enable Access Point to Access Point communications.
WDS Connections: SSID MAC Address Encryption Passphrase Router IP Router Subnet STP Page 41 Specify the SSID of the Access Point(s) to establish a WDS link with. Leave this field blank if you wish to nominate the Access Point by MAC address only – however in that case the Access Point must not have “SSID broadcast” disabled. Specify the MAC address of an Access Point to establish a WDS link with.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 3.11 User Manual Routing Rules When a WI-MOD-E receives an IP frame that is destined for an IP address on a different network, it checks if the network address matches the network address of one of its own interfaces (i.e. hard wired Ethernet, or wireless Ethernet, or WDS) and forwards the frame appropriately. However, if the IP network address does not match any of its interfaces, the WI-MOD-E will forward the frame to its default gateway.
The Routing Rules configuration page can be accessed by selecting the “Routing” link on any of the configuration web pages. Up to 30 routing rules may be added to each WI-MOD-E. The table below summarizes the configurable parameters of a routing rule. Name A name to describe the routing rule (Max 32 characters). Destination The destination network (or host) IP address (to specify a network address set the host address to 0. i.e. for a class C IP address 192.168.0.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 3.12 User Manual Wireless Message Filtering When configured as a Bridge, the WI-MOD-E will transmit all broadcast messages appearing at its wired Ethernet port. When the WI-MOD-E is configured as a Router, this does not occur. In many cases, the intended recipient of the broadcast traffic does not lie at the opposite end of a proposed radio link. Reducing unnecessary broadcast traffic sent over the radio link, will increase available bandwidth for data.
If radio links are chained together to form a radio backbone, it is also important to consider the operation of the Layer 3 Transparent Bridge (Refer Section 3.7). A WI-MOD-E Client will act as a MAC Address translator, as it acts as a MAC address proxy on behalf of devices connected to its wired Ethernet port. Addition of WI-MOD-E Client MAC addresses into intermediate WI-MOD-E units’ whitelist filters may be required for correct operation.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual IP Address Filter Configuration: Add Entries Enter the details of IP traffic to be added to the list. Protocols ARP, ICMP, TCP and UDP may be selected. Other IP protocols may be selected provided the IP protocol number within packets is known. TCP and UDP traffic may be also limited to specific port numbers. Delete Entries Check the delete box alongside entries selected for removal from the list.
If you wish to use routing over this serial network connection, then the IP addresses selected must not lie on Wireless or Wired Ethernet networks already configured into the device. You must ensure they set routing rules appropriately for devices either side of the network. If you want the serial device visible as present on the Wireless or Wired network, then the local IP address must be the same as the IP address set for the desired port.

3.13.2 Serial Gateway Serial Gateway functionality is available for both RS-232 and RS-485 ports independently, and enables serial data to be routed via the wired or wireless network connection. Serial Gateway functionality is similar to radio modem functionality, allowing point-to-point and multipoint serial data transfer. Each WI-MOD-E serial port may be configured as Server, Client, or Multicast Group. When configured as Server, the module will wait for a connection to be initiated by a remote client.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual There are software packages available (i.e. SerialIP Redirector by Tactical Software) that can create a virtual serial port on a PC. This virtual serial port can be configured to connect to a WI-MOD-E serial port. Standard programs can then be used to access this serial port as if it were actually connected to the PC. Alternatively the program telnet may be used to connect to a serial port on the WI-MOD-E.
3.13.3 ModBus TCP to RTU Gateway The ModBus TCP to RTU Gateway allows an Ethernet ModBus/TCP Client (Master) to communicate with a serial ModBus RTU Slave. The WI-MOD-E makes this possible by internally performing the necessary protocol conversion. The conversion is always performed by the WIMOD-E which is directly connected to the ModBus serial device (i.e. only this module needs to have ModBus TCP to RTU Gateway enabled).
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 3.14 User Manual Digital Input/Output The functionality of the shared Digital Input/Output pin may be configured via the “I/O Transfer” internal webpage. As this pin is shared, the Digital Input status will be ON when the Digital Output is set ON. The Digital I/O channel can be transferred to/from another device using ModBus (see section “3.15 ModBus I/O Transfer” below) or it can be configured to provide status of the module communications.
for ON and 0000(hex) for OFF. Inverted status registers are also provided where the registers contain 0000(hex) for ON and FFFF(hex) for OFF.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual An example of the ModBus functionality of the WI-MOD-E is illustrated below. In this example the status of the onboard digital input at C will be reflected at the onboard digital output at B. Also, 8 I/O registers from ModBus serial device D will be transferred to A. The ModBus configuration for unit C is shown below.
digital output at B. Local Register 4320 specifies the register for the onboard digital output at B (since B is the local unit at which the mapping is configured). I/O Count 1 specifies that only one I/O point is being transferred (i.e. the single digital I/O). Function Code 02: Read Discretes specifies the standard ModBus function code to read discrete (i.e. digital) inputs.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual the status of the I/O registers – including the I/O at units A, C, and D. This is a very powerful and flexible feature which could, for example, be exploited by a central monitoring facility or SCADA. The configurable ModBus I/O transfer options are summarized in the tables below.
3.16 Socket Routing TCP/IP Port forwarding The WI-MOD-E is primarily a TCP/IP Routing Server, to which a number of external TCP/IP Clients may connect. Since TCP/IP connections are point-to-point only, Socket Routing allows a number of remote TCP/IP clients to connect to the WI-MOD-E simultaneously, the WI-MOD-E can then route data between the separate remote client devices as necessary. Socket routing requires that the remote devices initiate the connection, so they must be acting as TCP/IP clients.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual Modes of operation As mentioned earlier, there are 3 modes of operation that the WI-MOD-E can use to route data between the connected devices: • Protocol Aware Routing. If the WI-MOD-E is aware of the protocol used by the remote devices then it can efficiently route data only to the required location based on the addressing inherent in that protocol. The WI-MOD-E currently supports the ModBus RTU protocol.
Routing Servers Configuration Master Port When a master/slave protocol is to be used by remote devices, specify the TCP Port number on the WI-MOD-E that the master device will connect to. Set this field to 0 if there is no master device. Slave Port Specify the TCP port number on the WI-MOD-E that non-master remote devices will connect to. Max Connections Enter the maximum number of devices that are allowed to connect to this Routing Server (default is 32, maximum is 50).
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual Max connections are set to 10 meaning that a total of 10 remote TCP/IP clients may connect to this Routing Server. ModBus Mode is selected so that the WI-MOD-E can route ModBus frames directly to their intended destination. Max Poll Fails is set to 5 – meaning that if 5 consecutive ModBus requests directed to a particular ModBus Slave fail to get a response then the routing table entry for that slave device will be deleted.
3.17 Module Information Configuration Module Information Webpage Fields This configuration page is primarily for information purposes. With the exception of the password, the information entered here is displayed on the root webpage of the WI-MOD-E. Password Configuration password. When changing the password on this screen, it will be sent unencrypted over any wired network. If encryption is enabled on the WI-MOD-E, any radio communications are encrypted, and therefore hidden from radio eavesdroppers.

4.2 4.2.1 Diagnostic Information Available Connectivity The Connectivity webpage at an Access Point lists all Clients with which it is associated. The page also indicates whether the encryption scheme has been authorized at the Access Point. A WIMOD-E will fail to be authorized if the encryption keys are incorrect. The received signal strength, background noise, and radio data rate is listed for each Client or Access Point by their MAC Address.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 4.2.2 User Manual Monitor Communications To monitor radio communications, it is necessary to configure the Operating Mode under “Network” as MONITOR. When in the MONITOR mode, the “Monitor Communications” function displays a continuous list of transmissions that are being received. As Beacon messages occur very frequently, they have been filtered out from the Monitor Communications display for convenience.
4.2.3 Statistics The Statistics webpage is used for advanced debugging of WI-MOD-E. This webpage details the state of the WI-MOD-E and its performance in the system. 4.2.4 Network Traffic Analysis There are many devices and PC programs that will analyse performance of an Ethernet network. Freely available programs such as Ethereal provide a simple cost effective means for more advanced analysis. By monitoring traffic on the wired Ethernet, a better idea of regular traffic can be discovered.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual If the signal is strong enough, a link may be established, and the Connectivity webpage of the Access Point may be opened. If the link is weak, the LINK led will go out, and the remote Connectivity webpage of the Access Point will fail to load. Using this procedure, the signal strengths of units at both locations may be analysed, and traffic is sent between the units whilst remote WebPages are opened. 4.4 4.4.
The screen shot below shows the response of the “ping 192.168.123.123 –t” command. This -t command is used to repeatedly ping the specified node in the network, to cancel use “Ctrl – C” A good test for the network once it is first set up is to use PING repeatedly from one PC’s IP address to the other PC’s IP address. This gives a good example of the networks reliability and how responsive it is from point to point. When you enter “Ctrl C” the program reports a packet sentreceived-lost percentage.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet 4.4.2 User Manual IPCONFIG IPCONFIG can be used to show your current TCP/IP information, including your address, DNS server addresses, adapter type and so on.

Appendix B GLOSSARY ACK Acknowledgment. Access point An access point is the connection that ties wireless communication devices into a network. Also known as a base station, the access point is usually connected to a wired network. Antenna Gain Antennae don't increase the transmission power, but focus the signal more. So instead of transmitting in every direction (including the sky and ground) antenna focus the signal usually either more horizontally or in one particular direction.
WI-MOD-E-100 & WI-MOD-E-300 Wireless Ethernet User Manual DHCP A utility that enables a server to dynamically assign IP addresses from a predefined list and limit their time of use so that they can be reassigned. Without DHCP, an IT Manager would have to manually enter in all the IP addresses of all the computers on the network. When DHCP is used, whenever a computer logs onto the network, it automatically gets an IP address assigned to it.
