890-007 Rev. A 01/28/99 Page 1 © 1999 RadioLAN, Inc. Introduction Historically, connecting two buildings to allow networking between two local area networks required the expense and effort related to running a cable from one building to another.
890-007 Rev. A 01/28/99 Page 2 © 1999 RadioLAN, Inc. RadioLAN allows you to connect two buildings, which are up to one mile apart, using a Campus BridgeLINK™ Processor Unit (CPU), a Companion Radio Module (CRM), and an 8.86” square directional antenna for each building link.
890-007 Rev. A 01/28/99 Page 3 © 1999 RadioLAN, Inc. The Campus BridgeLINK™ System The Campus BridgeLINK system includes the Campus BridgeLINK™ Processor Unit (CPU) with a mounting bracket, a Companion Radio Module (CRM), and a directional antenna.
890-007 Rev. A 01/28/99 Page 4 © 1999 RadioLAN, Inc. • The amber Fault LED illuminates for several seconds during the power-on diagnostic sequence. When the CPU is operating, this LED is normally extinguished. • The green Status 1 LED illuminates when the CPU detects the presence of the distant CPU.
890-007 Rev. A 01/28/99 Page 5 © 1999 RadioLAN, Inc. 10BaseT Port Jack Next to the MDI/MDI-X selector button you will find the 10BaseT port . The 10BaseT port interfaces the CPU to its local area network . The 10BaseT port is RJ45-compatible, which allows an eight-wire connection to a network hub or other hard-wired external device .
890-007 Rev. A 01/28/99 Page 6 © 1999 RadioLAN, Inc. CRM Port At the opposite end of the CPU, there is a female 15-pin D connector . The connector allows you to connect the CRM to the CPU, using the cable that is attached to the Radio Unit.
890-007 Rev. A 01/28/99 Page 7 © 1999 RadioLAN, Inc. The Companion Radio Module (CRM) The CRM interfaces the CPU with the directional antenna. The CRM is small, durable, and designed to insert easily into the mounting bracket that is attached to the CPU.
890-007 Rev. A 01/28/99 Page 8 © 1999 RadioLAN, Inc. Power Transformer The power transformer provides an easy connection to electrical outlets. One end of the transformer has a power cable with a connector that is compatible with the CPU’s power jack.
890-007 Rev. A 01/28/99 Page 9 © 1999 RadioLAN, Inc. Antenna Cable The antenna cable provided is a 15-foot, low-loss cable. It is made of fire retardant material, and is UV stabilized. Cold-shrink tubing is supplied to cover the antenna end connector after connection to the cable.
890-007 Rev. A 01/28/99 Page 10 © 1999 RadioLAN, Inc. A Typical Campus BridgeLINK™ Application Figure 8 shows a typical Campus BridgeLINK application in which two buildings, with local area networks in each, are located up to one mile away from one another.
890-007 Rev. A 01/28/99 Page 11 © 1999 RadioLAN, Inc. Figure 9 illustrates the networks inside each building. Notice that the CPU is attached directly to a hub, which connects network nodes together. Determining the Distance between Buildings It is important to verify that you do not exceed the distance capabilities of Campus BridgeLINK .
890-007 Rev. A 01/28/99 Page 12 © 1999 RadioLAN, Inc. Initial IP Address Setup Before you can use the TCP/IP management services of a CPU , it must contain a valid network IP Address .
890-007 Rev. A 01/28/99 Page 13 © 1999 RadioLAN, Inc. Temporarily Connect the CPU To use the IP ASSIGN Utility , you must first obtain a PC with a 10BaseT Network Interface Card that has its own IP Address. The PC must not be running a DHCP Server while performing this procedure.
890-007 Rev. A 01/28/99 Page 14 © 1999 RadioLAN, Inc. Using the IP ASSIGN Utility to Assign the CPU’s IP Address RadioLAN provides the IP ASSIGN Utility diskette with your package.
890-007 Rev. A 01/28/99 Page 15 © 1999 RadioLAN, Inc. Installing the CPU When installing a CPU you must mount it onto a wall or a ceiling. You must locate the CPU at a distance from the antenna that is no farther than the cable will allow.
890-007 Rev. A 01/28/99 Page 16 © 1999 RadioLAN, Inc. Locating the CPU After verifying that the CPU is located near a power source and network cabling, and is within the 15-foot cable distance constraint of the antenna, you must install the CPU securely to the mounting surface (for example, a wall or ceiling).
890-007 Rev. A 01/28/99 Page 17 © 1999 RadioLAN, Inc. Mounting the CPU When mounting the CPU , you must follow these steps. Before mounting the CPU to the mounting surface, connect the connector at the end of the CRM’s cable to the 15 pin D connector on the CPU (see Figure 13 ).
890-007 Rev. A 01/28/99 Page 18 © 1999 RadioLAN, Inc. Orient the CRM so that its cable does not cross over the mounting brackets and then insert the CRM into the mounting bracket so that it is flush with the rim of the bracket (see Figure 14 ). Orient the CPU on the mounting surface in the location where you would like it to be attached.
890-007 Rev. A 01/28/99 Page 19 © 1999 RadioLAN, Inc. Use a pencil to mark the brackets screw hole locations onto the surface upon which you will mount the CPU. At the location’s screw holes, install any necessary anchoring devices . This is especially recommended when installing the CPU onto a sheet-rock or gypsum surface.
890-007 Rev. A 01/28/99 Page 20 © 1999 RadioLAN, Inc. Grounding Considerations RadioLAN recommends that you properly ground the directional antenna as described in mounting hardware installation instructions and required by your local ordinances .
890-007 Rev. A 01/28/99 Page 21 © 1999 RadioLAN, Inc. Installing the Antenna There are many methods for mounting the antenna onto a wall. The assembly includes a U -bolt that allows you to connect the directional antenna to a standard size mounting assembly that is used for other directional antenna applications.
890-007 Rev. A 01/28/99 Page 22 © 1999 RadioLAN, Inc. Choosing the Best Mounting Height Make sure that you choose the appropriate mounting height for the directional antenna. You must consider the cable distance between the directional antenna and the CPU, and the level of accessibility for routing cable and mounting the CPU.
890-007 Rev. A 01/28/99 Page 23 © 1999 RadioLAN, Inc. Sighting Each Campus BridgeLINK™ Antenna Once you have installed and grounded the mounting bracket assembly (provided by others), you can point the directional antenna toward the location of the distant antenna.
890-007 Rev. A 01/28/99 Page 24 © 1999 RadioLAN, Inc. Sighting Procedure Campus BridgeLINK™ uses a 19° angle of reception for each of its antennas. This means that, from the center of the directional antenna, you can angle away from your target for as much as 9.
890-007 Rev. A 01/28/99 Page 25 © 1999 RadioLAN, Inc. 2 1 Apply Power to the CPU After verifying that the antenna cable is properly attached to the antenna and the CRM, and after making sure that the CRM is properly attached to the CPU , you can apply power to the CPU following these steps: 1.
890-007 Rev. A 01/28/99 Page 26 © 1999 RadioLAN, Inc. Adding Security to the Wireless Network As an option , you can contact RadioLAN to enable the Data Encryption feature. This feature secures the wireless link by setting an encryption key that protects your sensitive data on the wireless link.
890-007 Rev. A 01/28/99 Page 27 © 1999 RadioLAN, Inc. The CPU’s interface includes system security authentication passwords , so only remote users with the correct password can access and configure the CPU. The CPU offers up to three security access passwords, each configurable for read and/or write rights.

890-007 Rev. A 01/28/99 Page 64 © 1999 RadioLAN, Inc. Hello Time (1–10) Each time a network sends a frame, and no root bridge is present, the network sends a message that notifies other networks of its request to be the root bridge.
890-007 Rev. A 01/28/99 Page 65 © 1999 RadioLAN, Inc. Enter the number of seconds (between 4 and 30) that the bridge will wait for the primary port to pass a frame before switching the secondary port into the forwarding state, so that the secondary port can route data when the primary port fails to do so.
890-007 Rev. A 01/28/99 Page 66 © 1999 RadioLAN, Inc. Port Priority (0–255) Bridges associate ports with physical devices , such as a router jack. A bridge can associate one or more ports with a physical interface. Each port is associated with a port priority, which contributes the topology of the network.
890-007 Rev. A 01/28/99 Page 67 © 1999 RadioLAN, Inc. Interrogating the System for Performance Information Performance is a combination of speed and accuracy. When the CPU transmits at higher rates, and retransmits packets fewer times, it has a higher rate of performance.
