Connect it to the outdoor Subscriber Unit and the indoor junction box. 4.
Company Proprietary 7.2 Installing Mounting Pole Once you have selected a site for installing the outdoor transceiver/Subscriber Unit, determine what type of surface you will use for your installation. Select from the following list: • Installing on a Brick Or Masonry Wall • Installing on a Wall With Wood Siding • Installing on an Antenna Mast The following sections describe the installation procedure for each of the above. 7.2.
Company Proprietary 4. Set the mounting pole aside. 5. Using a ¼ inch masonry drill bit, drill holes approximately ½ inch deep at the marked locations. 6. Insert the anchor sleeves into the drilled holes. Using a small hammer, gently tap the anchor sleeves into the masonry until tight. Check that the anchor sleeves are flush with the wall. (Figure 6-3) 7. Align the mounting pole with the drilled holes. 8. Insert a lag bolt in each of the holes and hand tighten. 9.

Company Proprietary 1. Select a location for the junction box. This should be: • Somewhere you can easily connect to your PC and a power outlet. • Somewhere that is accessible for service and troubleshooting (not too close to the floor). 2. Remove the two screws which attach the junction box faceplate to the wall mount. 3. Set aside the faceplate with PCB and jack. Attention! Be careful not to damage the two LEDs when removing the PCB. 4.
Company Proprietary NOTE - Add a drip loop at wall penetration to prevent water from entering Figure 7-8 Interconnect Cable Routing Solutions 2. Once you have chosen the route, determine the length of cable required. Allow three extra feet on each end to allow for strain relief as well as any bends and turns. 3. Install the cable, leaving the ends free and ready to fit the RJ-45 connector (transceiver end), and install to the indoor junction box. 4.
Company Proprietary NOTE: The Grommet is made of a special conductive material used to complete the ground between the Subscriber Unit and indoor junction box. Figure 7-9 Grommet Location -- Underside of Subscriber Unit 2. Insert the cable end through the grommet clamping plate (Figure 7-10). 1. Insert the cable end through the grommet. The tapered end of the grommet should be opposite the cable end. 2. Strip 1 inch of insulation off the cable end.
Company Proprietary 4. Separate the twisted pair wires and align by color code in the order listed in the following Table 7-7.

Using pin 1 as a reference, insert the individual wires into the channels of the RJ-45 connector.
Company Proprietary 7.5.3 Connecting to the Outdoor Subscriber Unit Transceiver Now that you have prepared the interconnect cable, you are ready to connect the cable to the outdoor Subscriber Unit. Attention! Always Disconnect Power from wall box BEFORE inserting RJ-45 connector into transceiver. This prevents arcing damage from occurring. 1. Insert the RJ-45 connector into the receptacle located underneath the outdoor Subscriber Unit (refer to Figure 6-9).
Company Proprietary 2. Insert the cable end through the notched out section of the junction box. 3. Reinstall the PCB into the junction box using the two screws, allowing enough of the interconnect cable to be able to reach the punch down block and wrap around the mounts of the cover plate for strain relief. 4.

Company Proprietary SECTION 9 Testing the System 9 Testing the System 9.1 Introduction This section explains how to: • Power up your AB-Access System • Use a PC (known as the Test PC) to check the alignment of your outdoor transceiver • Make sure you have the best connection to your service provider. Attention! This operation may need two people – one to operate the Test PC and one to align the outdoor transceiver.
Company Proprietary Attention! If the yellow LED is on, this indicates that power is being supplied to the unit. If not, check the connections. 9.4 Configure The IP Address 1. Switch on the Test PC. 2. Configure the Test PC to use the recommended IP address supplied by your system provider or installer (example: 192.168.3.1). 3. Configure the Test PC to use the recommended netmask supplied by your system provider or installer.
Company Proprietary To take advantage of this information, the AB-Access Subscriber Units contain an interface, which allows the installer to properly align the unit. Once an SU is mounted in place and roughly aligned using a compass, the installer can attach a computer to the terrestrial interface of the SU and interact with the RSSI web page on the SU to perform alignment (reference Figures 9-1 and 9-2).
Company Proprietary Figure 9-2 RSSI Sample Web Page 1. Note the desired channel for registration (example, Channel 14, horizontal polarization). 2. Attach a computer to the terrestrial interface of the SU. 3. Change computer IP address to be in the same subnet as the SU. For example, set the computer to address 192.168.254.1 to connect to an SU with the IP address of 192.168.254.254. 4. Verify connectivity to the SU using the Ping utility (example, ping 192.168.254.254) 5.
Company Proprietary http:///installation/step2 (ex http://192.168.254.254/installation/step2) 7. This will display two columns of data, one column for RF channels using horizontal polarization and a second for vertical polarization. Turn the SU in 2 degree arcs until the channel desired is listed as “Good” and is green in color. 8. Click on the “next” button to initiate registration of the SU with the AB-Access network.
