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. This may have involved installing an aerial cable or digging a trench and installing conduit and wiring between the two buildings, which is time-consuming, labor-intensive, and costly. After installation, cable degradation, due to moisture, corrosion, or alterations in landscaping, can compromise the network connection

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. When using the Campus BridgeLINK™ application, you need only install the components at each building, aim the antennas toward one another, and power the system on. The only requirements for each building location are Campus BridgeLINK™ system components and access to network c

Local Port The Campus BridgeLINK™ System The Campus BridgeLINK system includes the Campus 10BaseT Port BridgeLINK™ Processor Unit (CPU) with a mounting bracket, MDI/MDI-X a Companion Radio Module (CRM), and a directional antenna. Selector Also included is the power transformer that you can plug into a Status LEDs: non-switched electric outlet. You can install these items in plain view, hidden away in a closet, or above ceiling tile. Power Fault Jack Campus BridgeLINK™ Processor Unit (CPU) The CP

• 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. When the CPU is operating, this LED normally illuminates when the near and far CPUs are active. • The green Status 2 LED illuminates when the CPU detects the presence of data passing through the wireless link. During normal CPU operation, this LED flic

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 or other hard-wired external device . 10BaseT LED Indicators On the upper left and right corners of the 10BaseT port are green LEDs which indicate transmit and receive status from the network. When the CAR LED illuminates, this indicates that the Ethernet ca

CRM Port At the opposite end of the CPU, there is a female 15-pin CRM D connector . The connector allows you to connect the CRM to the CPU, using the cable that is attached to the Radio Unit. Mounting Bracket Mounting Bracket The mounting bracket is specially shaped so that it allows the CRM to slide into the mounting bracket before securing the CPU to a flat surface.

The Companion Radio Module (CRM) Directional Antenna The CRM interfaces the CPU with the directional antenna. The Connector (Type N) CRM is small, durable, and designed to insert easily into the mounting bracket that is attached to the CPU. On one end of the CRM, there is a Type N connector and an LED indicator. The Type N connector attaches the CRM to the directional antenna . The LED illuminates amber when the CRM is transmitting data. It illuminates green when the CRM is receiving data. Acti

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. The other end plugs into an electrical outlet. RadioLAN recommends using a non-switched electrical outlet for connection to the CPU. Figure 5 : Power Transformer The directional antenna assembly includes the directional antenna and a mounting clamp. The directional antenna is a 18dbi-gain, small-prof

Figure 8 shows a typical Campus 8.8“ Directional Antenna BridgeLINK application in which two buildings, with local area networks in each, are located up to one mile away Up to 1 Mile Apart from one another. Notice that there are no solid obstructions between the two buildings and that each building antenna points toward the other. Because the system uses radio frequency to establish the connection between the two buildings, it is important to avoid blocking the radio link with any objects, such
