Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Access Point vs. Client The Access Point unit acts as the “wireless master” unit. The Access Point accepts and authorizes links initiated by client units, and controls the wireless communications. Clients (Stations) are slave units and when connected to the Access Point becomes transparent Ethernet link. The first diagram shows a connection between two Ethernet devices using BU-245U-E Ethernet modems.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Bridge vs. Router Each BU-245U-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.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual 1.2 Getting Started Quickly Most applications for the BU-245U-E require little configuration. The BU-245U-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 Chapter 2, “Installation.” The BU-245U-E requires an antenna and a power supply.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual CHAPTER 2 INSTALLATION 2.0 General The BU-245U-E modules are housed in a rugged aluminum case, suitable for DIN-rail mounting. Terminals will accept wires up to 2.5 mm2 (12 gauge) in size. All connections to the module must be SELV (Safety Extra Low Voltage). Normal 110-250V mains supply must not be connected to any terminal of the BU-245U-E module. Refer to Section 2.3 Power Supply.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Dual Antenna Installations Most installations in industrial plants and factories use single omni-directional antennas. Installations can suffer from “ multi-path fading” effects where multiple reflected radio signals adversely affect the signal strength. This can be checked by moving the antenna a short distance (10 cm or 4 inches) - if the signal increases significantly then there are multi-path effects.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Installation tips Connections between the antenna and coaxial cable should be carefully taped to prevent ingress of moisture. Moisture ingress in the coaxial cable is a common cause for problems with radio systems, as it greatly increases the radio losses.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Directional Antennas. Directional antennas can be a: • Yagi antenna with a main beam and orthogonal elements, or • Directional radome, which is cylindrical in shape, or • Parabolic antenna. A directional antenna provides high gain in the forward direction, but lower gain in other directions. This may be used to compensate for coaxial cable loss for installations with marginal radio path.

If a connected device is a DHCP server, the local and remote BU-245U-E units can be configured as DHCP Clients and receive IP addresses from the server device.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual 3.12 Spanning Tree Algorithm The bridge “Spanning Tree Protocol” function was introduced to handle network loops and provide redundant paths in networks. To enable tick the STP box on any “WDS Connections” you have configured on the “Repeaters” configuration page. For example, consider this network with a redundant wireless link.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual 3.13 Compatibility 3 Address (Layer 3 Bridge) & 4 Address Mode What Addresses are in a wireless Ethernet data frame? There are two different Wi-Fi communication “modes”, 3 Address and 4 Address Modes. Each mode has a slightly different way that it addresses the data frames to other devices on the network.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual 240U-E Compatibility BU-245U-E-G modules can communicate with Cooper Bussmann 240U-E Ethernet modems however only in certain modes. The following table shows compatible configurations. If communicating with Cooper Bussmann 240U-E Ethernet modems the 240U-Es need to be configured with WDS (4 address mode), not the default “3-address mode” and the 240U-E APs cannot be auto connect to any WDS AP.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual WDS bridge interfaces have the advantage that redundant paths are permitted when using the bridge Spanning Tree Protocol (see section 3.11 “Spanning Tree Algorithm”), thus behaving as a self-healing mesh network. Bridged networks are also not as configuration intensive as routed networks. Since WDS bridge interfaces generally do not require IP address configuration (they inherit the IP address of the standard wireless interface).
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Example – Extending Range Using WDS One of the most common uses for WDS is to extend the range of the wireless network using repeaters. The diagram above illustrates a simple example where the four Access Points are all at fixed locations (each of the Access Points could, of course, have one or more client/stations connected).
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Example - Roaming with WDS Access Points Another common use for WDS is extending the range across a large wireless network but allowing roaming connections between access points or being able to switch to the next Access Point when out of range of the previous Access Point.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Example – Adding Redundancy In the example below, 4 x Access Points (A, B, C, & D) form a mesh network using only WDS bridge interfaces. Each of the Access Points may also have its own clients associated. Each Access Point is configured with a different SSID, meaning the clients associated with each Access Point are fixed.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual The configuration for Site A and B are shown below. In this example, Site B uses its primary access point to act as an access point for Virtual Stations on Site A and D, and uses a Virtual Station to act as a client to Site C. Site A uses two Virtual Stations to act as clients to Site B and to Site C.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Example – WDS Routed Network 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.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual So, in this example, Site B has a total of three IP addresses: 192.168.5.3 for the default interface; 169.254.0.3 for the WDS link to Site A; and 169.254.5.3 for the WDS link to Site C. Note: We choose to always use the same host address of 3 for unit B on all of its interfaces regardless of the network address. • The first routing rule specifies 192.168.0.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual 3.15 Routing Rules When a BU-245U-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.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual 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 BU-245U-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.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual • The IP Address filter checks both the source address and the destination address of the message. If either address match, then the rule is activated. • ARP filtering applies only to ARP request packets (typically these are broadcast packets) which are sourced from the Ethernet interface and destined for the wireless interface. (ARP requests from devices on the wireless network will always be passed to the Ethernet interface.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual Select “Blacklist” or “Whitelist” Blacklist will prevent all listed devices from accessing the module and using the radio link. Whitelist will allow devices with the MAC addresses listed to communicate with the module and utilize the radio link. All other devices are blocked. Add Entry Add a row to the table of Mac Address filter rules Delete Entry Delete the currently selected MAC address filter rule.
Cooper Bussmann BU-245U-E Wireless Ethernet & Device Server User Manual ARP Filter Configuration ARP (Address Resolution Protocol) is a broadcast message and is primarily used for finding a MAC address when only its IP or some other Network Layer address is known. On large networks, you generally tend to get a high proportion of broadcast messages.
