iv Installing and using the Expedience OSU

1WelcomeThis document describes how to install and use the Expedience outdoor subscriber unit (OSU) to obtain wireless high-speed Internet access. Subscribers can connect the OSU to a computer or to a small office/home office (SOHO) local area network (LAN) through a hub, switch, or router.This document is intended for use by professional equipment installers. Subscribers of the high-speed Internet service should not attempt to install the OSU. For questions about OSU operation or installation, subscribers should contact the ISP that supplied the OSU device. Before you beginThis section describes items the installer or subscriber must purchase before the OSU is installed. This section also describes items you need to have available and things to consider before beginning the OSU installation.Additional material required for installation• The subscriber’s computer must be equipped with an Ethernet network interface card (NIC). The NIC is not provided with the OSU, but subscribers can purchase a NIC at most computer and electronics stores.• An RJ-45 Ethernet cable to connect the OSU plug-in power supply with the user’s computer.• Ground wire of sufficient length to run between the OSU and a ground rod. • It is recommended that the ground wire be an 8 AWG, solid aluminum or copper wire.• It is recommended that the ground rod used be 8 feet (2.5 m) copper. Note that most buildings have an existing ground rod outside, at the main power connection site. If desired, you can install a rod into the ground outside the building. • Anti-seize compound to be applied to the stainless steel screws that hold the OSU to the mounting bracket.• If you mount the OSU on a brick or masonry surface, lead screw anchors are required. Pre-installation planning• Find an appropriate location on the outside of the building to mount the OSU. • To provide Internet service, the OSU communicates with a base station on the service provider’s communications tower. The service provider must provide you with information about the nearest communications tower. For example, if the tower nearest to the building is north of the building, you will install the OSU on the north side of the building.• Mount the OSU on a high location on the building, such as under the eaves.

5Installing the OSUThis section describes how to find an appropriate installation location for the OSU and how to install the OSU on the building. Selecting an installation location for the OSUIt is recommended that you determine the optimum installation location for the OSU before physically mounting the OSU to the building. There are two methods you can use to determine the best installation location for the OSU.Using an RSU to detect signal from a base stationThe first method uses a residential subscriber unit (RSU). The RSU can detect where a signal from the service provider can be received at the installation site. Most often if you mount the OSU on the side of the building facing the service provider's base station, the OSU can detect adequate signal in order to provide high-speed Internet access. However, unless there is an obvious line of sight to the correct base station, the correct orientation of the OSU is often not apparent. There also may be practical reasons why you cannot mount the OSU on the side the building that faces the base station. To use the RSU to determine where you might be able to install the OSU on the building, point the back of the RSU in the direction in which the OSU is to be oriented. The back of the RSU is the side without logos. At each direction you point the RSU, note the number of blinking lights on top of the RSU. The stronger the signal that the RSU can detect, the more lights blink on and off. After determining where signal can be detected around the building, you can then choose a corresponding OSU installation location on the building. As you attach the OSU to the building, make sure to point it in the same direction that the RSU was pointed when the RSU detected a signal. Note: When detecting signal at the site, you must use an RSU that has the same vertical or horizontal polarization as the OSU to be installed. Using LinkMonitor application to detect signal from a base stationThe second method of detecting signal from a base station uses the OSU and the LinkMonitor program that ships on the CD-ROM. The installer connects the OSU to power and to the installer’s computer. Then, the installer follows the procedure described in the section “(Optional) Finding the strongest service provider signal” on page 12 in this guide.Installation overviewTo install the OSU:1Attach the mounting bracket to the outside of the building.2Set the OSU inside the mounting bracket.3Tighten the lower mounting bolt to hold the OSU in place. The following sections describe these steps in greater detail.

6Installing and using the Expedience OSUAttach the mounting bracket to the outside of the building1Where possible, install the OSU on the side of the building that has the greatest exposure to the communications tower of the service provider. The service provider can provide information about tower locations that can provide the OSU with greatest signal exposure. 2Install the mounting bracket to the building. The bracket (like the OSU) must be installed vertically. • Drill the two top holes 1.25 inches (3.2 cm) apart. Drill the bottom holes 7 inches (18 cm) below the top holes. Figure 5 provides a template for drilling the holes. • If possible, drill one upper hole and its corresponding lower hole into a stud. Do not allow the OSU to be supported by the building’s siding only. • If installing the OSU on a brick or masonry surface, use lead screw anchors.• After the holes are drilled into the building, drive the screws (illustrated in Figure 4) through the holes on the mounting bracket and into the building. Figure 4 illustrates the screws to use to attach the mounting bracket to the building. Figure 4 Screws to attach mounting bracket to building

8Installing and using the Expedience OSUSetting the OSU inside the mounting bracketNote: The OSU must be installed vertically. The OSU has a peg on top, and a peg on bottom. The upper and lower pegs snap into the mounting bracket’s peg holes.To install the OSU in the mounting bracket:1You must install the OSU vertically. To do so, make sure the bottom of the OSU faces the earth. This is the side of the OSU labelled with a sticker “MOUNT THIS SIDE DOWN”. The sticker is illustrated in Figure 7.2On the bottom arm of the mounting bracket, snap the OSU’s peg into the peg hole. 3On the top arm of the mounting bracket, snap the OSU’s upper peg into the adjustment arch. To accommodate the height of the peg, you may need to lift the mounting bracket’s edge up slightly.Partially tightening adjustment screws to hold OSU in placeTo make sure the OSU doesn’t slip out of the mounting bracket, partially tighten the screws in the adjustment arch.If you still need to pivot the OSU along the adjustment arch—in order to find the strongest signal from the service provider—do not fully tighten the screws yet. You will fully tighten the screws after finding the strongest signal from the service provider. When the screws are fully tightened, the OSU will no longer move along the adjustment arch.Note: Before mounting the OSU in the bracket, apply an anti-seize compound to the screws used in the assembly.

9Figure 8 illustrates how the screw, split lock, flat washer and double-tab washer are put together.1For the top of the mounting bracket, assemble the bolt (coated with anti-seize compound), split lock washer and flat washer as shown in Figure 8.2For the bottom of the mounting bracket, assemble the bolt (coated with anti-seize compound), split lock washer, flat washer, ground wire, and double-tab washer, as shown in Figure 8.Let the ground wire dangle to the ground. 3On the upper arm of the mounting bracket, insert the bolt through the adjustment arch on the mounting bracket. 4Partially tighten the bolt on the OSU to hold it in place.Figure 8 Mounting bracket screw assemblyBolt, coated withSplit lock washerFlat washerBracketSolid ground wireSplit lock washerFlat washerDouble tab washerBolt, coated withTop of unitBottom of unitanti-seize compoundanti-seize compound

10 Installing and using the Expedience OSU5On the bottom are of the mounting bracket, partially tighten the bolt on the bottom of the OSU. 6Plug in the circular end of the Ethernet/power cable in the bottom of the OSU. Provide strain relief by making a loop in the cable and strapping it to the lower part of the mounting bracket. Note: You will fully tighten both bolts in the section, “(Optional) Finding the strongest service provider signal” on page 12.Running cables through building’s wallThe power/Ethernet cable runs from inside the building to the OSU.1In the desired location, drill a 3/4 inch (18 mm) hole through the wall. 2Draw one end of the RJ-45 cable through the hole. 3Route the RJ-45 power/Ethernet cable to the location where the power supply is to be plugged in. 4After completing the installation, seal the hole with a silicone or acrylic caulking material. Connecting the ground wireThe OSU must be grounded to a ground rod in the earth near your building. Make sure your ground cable does not exceed a 50 foot maximum to the ground rod.To ground the OSU:1Connect the ground wire from the OSU to the ground rod in the ground next to the building.2Attach all wires to the building by using electrical staples. Use drip loops as needed.

11Installing a data line protectorIt is recommended that you use a data line protector to connect the OSU to the user’s LAN or computer. The data line protector provides protection against static electricity and momentary lightning surges on the OSU cable and the subscriber’s LAN, to the OSU, the user’s computer, and other devices that may be connected to the local Ethernet LAN. The recommended data line protector can be ordered from NextNet Wireless, using the part number 585-9000-3414.Figure 9 illustrates how the cables are connected through the data line protector and into the power supply cord. Note: So that the data line protector can provide protection to the OSU and user’s LAN-connected equipment, the furnished ground cable must be connected to a good earth ground or equivalent as required in article 250 of the National Electric Code. Failure to provide correct grounding to the data line protector could result in damage to the user’s computer or LAN-connected equipment.

12 Installing and using the Expedience OSUPlugging in the power supply1Plug the RJ-45 cord from the OSU into the jack labelled “OSU/power” on the power supply.2Use a standard, category 5 Ethernet cable to connect the computer to the jack labelled “computer” on the power supply. Caution: Make sure that the RJ-45 cable from the OSU and category 5 Ethernet cable to the computer or network hub are connected to the correct jacks as described in the section “Installing a data line protector‚” in this manual. If the cables are not connected correctly the OSU will not work, and damage to the user’s computer could result. 3The power cord uses standard household power. Plug the power cord in the power source.(Optional) Finding the strongest service provider signalNote: The following sections describe additional methods of optimizing the orientation of the OSU, if necessary. You can use the subscriber’s computer or a laptop computer to complete these procedures. The OSU is equipped with an internal antenna. To provide the best service, the OSU searches for the strongest signal transmitted by your service provider.You can find the strongest signal from your service provider by using one of the following methods:• Software-assisted method• Sound (auditory) methodBoth methods require you to install the LinkMonitor programInstalling the LinkMonitor program1Locate the software CD supplied with your OSU. 2Insert the CD into your computer’s CD drive. If the installation program does not start automatically, start it by clicking on the Setup.exe icon.3Follow the instructions in the dialog boxes to complete the installation of the LinkMonitor program.4After the software is installed, a blue RSU icon appears in your computer’s system tray.To run the LinkMonitor program, right click on the icon, and select Open.Figure 10 Starting the LinkMonitor programLinkMonitor program’s icon in system tray

13The Expedience LinkMonitor window appears (Figure 11).Using the software-assisted method to find the strongest signalNote: It is beneficial to have two people perform this procedure if you want to use the subscriber’s computer instead of your own laptop computer. One person will monitor software statistics inside the building. The other person will rotate the OSU outside the building.To scan for the strongest signal from your service provider:1Install the LinkMonitor program as described in the section “Installing the LinkMonitor program” on page 12. 2On the LinkMonitor window, click Start Scan. 3Return to the OSU on the side of the building. 4Slowly rotate the OSU along the adjustment arch. Stop the rotation at every 15 degrees for 5 seconds. Note the score reported by the LinkMonitor program, as described in step 5. 5The LinkMonitor program searches for a signal from your service provider. In the Channel Score group, the strength of the signal received at the starting position is indicated in two ways:• The indicator bar shows varying levels of red, yellow, and green. Red indicates weak signal strength, yellow indicates moderate signal strength, and green indicates strong signal strength.•The Current Score field shows the signal strength. During this procedure, the program compares the Current Score to the Best Score. Best Score indicates the strongest signal the program has ever seen during the scanning procedure.Figure 11 Expedience LinkMonitor window

14 Installing and using the Expedience OSU6Remembering the strongest signal reported, re-orient the front of the OSU in the direction that the OSU was pointed when the strongest signal was found.7Tighten the bolts fully that hold the OSU in place. 8Return to the LinkMonitor program. Click Stop Scan. Using the sound (auditory) method to find the strongest signalTo use the sound (auditory) method to find the strongest signal:1Install the LinkMonitor program as described in the section “Installing the LinkMonitor program” on page 12. 2On the LinkMonitor window, click Start Scan.3Return to the OSU outside. You should hear the OSU beeping. • The OSU uses beeps to indicate the strength of the signal that the OSU can detect. The strength of the signal detected is indicated by the frequency of the beeps as compared to the pause between beeps. A constant beep with no pause indicates that a strong signal is detected by the OSU. One beep followed by a long pause indicates that a signal can be found, two beeps followed by a shorter pause indicates that a stronger signal is detected, and so on. • If the unit beeps twice, then pauses, then beeps twice, and so on, this indicates that the unit is scanning for service. If this beeping pattern is not broken, this indicates that the OSU cannot detect a signal. 4Rotate the OSU along the adjustment arch, noting how frequently the OSU beeps. 5Point the OSU in the direction where the beeps are most constant. 6Tighten the bolts. 7Return to the LinkMonitor program and click Stop Scan.Setting up the computer to receive an IP addressThis section describes how to set up various Windows operating systems that might run on the host computer so that the computer can receive an IP address.You can set up the host computer or router so it can dynamically receive an IP address. If desired, the subscriber can request a static IP address for the host computer or router.Note: If the subscriber uses a non-Windows operating system, check help file of the operating system.

16 Installing and using the Expedience OSUConfiguring IP address assignment for routersFor instructions on how to assign a static IP address to a router, or to set up the router to use DHCP to receive an IP address, refer to the documentation that accompanied the device.Connecting to the InternetTo connect to the Internet:Start your Internet browser, and try to open a few Internet sites.• If you can open numerous sites, enjoy your new, high-speed service.• If yon cannot open any sites—for example if your browser displays a message “This page cannot be displayed” for all the sites you tried to access—restart the computer OR refresh the OSU’s connection, as described in the section “Refreshing the OSU’s connection” on page 16.Refreshing the OSU’s connectionWhen you refresh the OSU’s connection, your service provider is assigning your computer a new IP address. You need to refresh your OSU’s connection with your service provider when your Internet browser does not let you open any Internet sites.Windows users: Refreshing the connectionThe OSU’s connection is refreshed when you restart the computer. To refresh the connection without restarting the computer:1Make sure you have installed the LinkMonitor program.2In the system tray, right click the blue RSU icon (Figure 10) and select Open. 3In the window that appears, on the Local Net Config tab, click the Renew IP Address button.Non-Windows users: Refreshing the connectionIf you do not run the Windows operating system, you can reboot your computer to refresh the connection. You may want to refer to your operating system’s help files to determine if other methods exist to refresh the connection (that is, to find a method for refreshing the IP address).

17Connecting the OSU to a networkNote: Use only one OSU on a network. Do not use multiple OSUs on the same network.To directly connect the OSU to a computer, use an Ethernet cable (also known as a straight-through cable).However, to connect the OSU to a hub or switch, use an Ethernet cable appropriate for your network device. This might be a straight through or cross-over cable, depending on how your network device switches signals. When determining how to set up your network, remember that the OSU device operates as a hub or a bridge. After connecting the OSU to the network device, power the OSU and scan for a service provider signal, as described in earlier sections of this guide.
