These limits are designed to provide reasonable protectionagainst harmful interference in a residential installation.  This equipment generates, uses and canradiate radio frequency energy and if not installed and used in accordance with the instructions, maycause harmful interference to radio communications. However, there is no guarantee that interferencewill not occur in a particular installation. If this equipment does cause harmful interference to radio ortelevision reception, which can be determined by turning the equipment off and on, the user isencouraged to try to correct the interference by one or more of the following measures:- Reorient or relocate the receiving antenna.- Increase the separation between the equipment and receiver.- Connect the equipment into an outlet on a circuit different from that to which the receiver isconnected.- Consult the dealer or an experienced radio/TV technician for help.This equipment has been certified to comply with the limits for a class B computing device pursuant toFCC Rules.  In order to maintain compliance with FCC regulations, shielded cables must be usedwith this equipment.  Operation with non-approved equipment or unshielded cables is likely to resultin interference to radio and TV reception.  The user is cautioned that changes and modificationsmade to the equipment without the approval of the manufacturer could void the user's authority tooperate this equipment.FCC Maximum Permissible Exposure GuidelinesIn 1996, the FCC adopted new guidelines for evaluating environmental effects of RF emissions.  Theset limits for Maximum Permissible Exposure (MPE) to RF energy in the 2.4 GHz band, where theRadioWire Modem operates, is set at 5 mW/cm2 for Occupational/Controlled Exposures and1 mW/cm2 for General Population/Uncontrolled Exposure.  Occupational/Controlled limits apply insituations where persons are exposed as a consequence of their employment, provided that thosepersons are fully aware of the potential for exposure and can exercise control of their exposure.Uncontrolled Exposure applies to situations where the general public may be exposed and may notbe fully aware of the potential for exposure or can not exercise control over their exposure.The RadioWire Modem (RWM) should be installed by a competent technical person who understandsthe potential for exposure and can exercise proper judgement during the installation of this product.Radio Connect Corporation (RCC) recommends that the RWM be installed in a location wheremembers of the general population cannot walk into the direct RF path or touch the antenna.  This isnecessary both to ensure a reliable connection and to avoid unnecessary exposure to RF emissions.
Wireless Internet Service Link - User's ManualDRAFT iiiRCC recommends that the installation of the RadioWire Equipment is done with the equipment off toeliminate the risk of unnecessary exposure to RF energy.  When fine tuning the direction of theantenna, keep your RF exposure time to a minimum if you need to place hands or other body parts inlocations listed in the special cases below.  Normal installation of this product is possible withoutexposure to RF levels in excess of MPE limits for Controlled Exposure.With installation per RCC recommendations, the RadioWire Modem does not generate power densitylevels in excess of the MPE Limits for General Population/Uncontrolled Exposure.  Be aware of thesituations where the limits for Occupational/Controlled Exposures are approached or exceeded.These are:  Maximum Permissible Exposure (MPE) limits for Uncontrolled Exposure is exceeded fordistances closer than 22.4 cm (9 inches) from the helical antenna within the 35o beamwidth.  MPE limits for Controlled Exposure is exceeded for distances closer than 10 cm (4 inches) fromthe helical antenna within the 35o beamwidth.  MPE limits for Controlled Exposure can be exceeded in the area between the reflecting surface ofboth the 0.6m and 1m dish and the actively radiating antenna.  For the 0.6 meter dish, the MPE limits for Uncontrolled Exposure is exceeded on the reflectingsurface of the dish.As noted above, RCC recommends that this equipment be installed so these situations are notgenerally possible.Reader ResponseWe at RadioConnect encourage you to respond to our products and documentation.

Wireless Internet Service Link - User's Manual Section 2: System Description2-1 DRAFT2 System Description2.1 RadioWire ModemThe RadioWire Modem is housed in a cast aluminum casing designed to withstand severeweather conditions.  It contains no parts that require user access, and should not be openedby anyone except RadioConnect's authorized service personnel.2.1.1 Alignment IndicatorsTwo alignment indicators are inset into the underside of the RWM case for ease of viewingfrom a distance and in bright sunlight. These indicators are light emitting diodes (LEDs) -one green, and one red:Figure 2-1.  Alignment Indicator LEDsThe indicator lights have the following functions:Green = Received Signal Level/AcquisitionAfter signal acquisition, this green LED flashes at a rate proportional to the signallevel.  Low signal levels will cause a slow blinking, while higher levels will cause theblink rate to increase.  At very high levels, the LED to appear to be on continuously.Red = Packet error:Indicates the occurrence of a link level error.   The flash rate matches the rate atwhich packet errors occur.  Unless link error correction has been disabled, automaticerror correction is performed by the modem.RedGreen
Wireless Internet Service Link - User's Manual Section 2: System Description2-2 DRAFT2.1.2 AntennaFigures 2-3 through 2-5 provide details of the three antenna types available with the RWM.It is not necessary to use the same type of antenna at the two ends of a link.  The actualcombination depends on the range required.  Table 2-1 shows the range capabilities of eachpossible combination in free space conditions, assuming that a link margin of at least 25 dBis pre-requisite.  Note that the upper limit of 20 miles is governed by protocol constraints,and not by the antenna gain.Helical 0.6m dish 1.0m dishHelical Range:  5 miles (8 km)Link margin:  25.7 dB0.6m dish Range: 10 miles (16 km)Link margin:  25.7 dB Range: 20 miles (32 km)Link margin:  25.7 dB1.0m dish Range: 16 miles (26 km)Link margin:  25.5 dB Range: 20 miles (32 km)Link margin:  29.7 dB Range: 20 miles (32 km)Link margin:  33.7 dBTable 2-1.  Range and Link Margin with Different Antenna Combinations2.1.3 Mounting BracketRadioConnect antenna mounting brackets are designed to allow tilting in the vertical plane,to accommodate elevation differences between the RWM units at the two ends of a link.This capability is especially useful for relatively short links.  The brackets are calibrated withtilt angles above and below horizontal.  Once the RadioWire Modems have been installedand aligned with each other, and the brackets firmly locked in their optimum positions, youshould record the tilt angles read from the mounting brackets, in your ConfigurationWorksheet.2.1.4 RWM-to-NIM CableThe cable that runs between the roof-mounted RWM and thein-building NIM is a special serial cable that carries lowvoltage power up to the RWM, as well as carrying databetween the units.  This cable is offered in standard lengthsfrom 25 feet to 200 feet, and in two different fire-resistanceratings - standard or plenum-rated.  Custom lengths are alsoavailable to special order.  Check that the lengths of thecables you receive match your order, and if there is anydiscrepancy, notify your reseller as soon as possible.The standard PVC cable is satisfactory for use in vertical wallcavities and shafts, while plenum-rated cable is required forrouting through under-floor plenum space.  In either case, thecable is supplied as a kit, with the connector not installed atone end in order to facilitate feeding the cable between theRWM and NIM.  The connector for attachment to the RWM ismolded on to the cable, while the DB-25 for attachment to theNIM is not installed.  Instead, the open end of the cable has asleeve on it, as shown in Figure 2-2.CablePins forinsertioninto DB-25connectorProtectivesleeveFigure 2-2.  NIM End ofCable, as Shipped.

It may be installed as a stand-alone unit, or pairs of NIM units maybe coupled together side-by-side and mounted in a standard 19" rack.  RadioConnect offersa custom kit for this purpose (part number 250-0001-00).  When installed in a rack, the NIMunits occupy 1U height.2.2.1  Rear Panel ConnectorsFigure 2-6.  Rear PanelThe NIM rear panel is illustrated in Figure 2-6.  The following connectors are present onboth models of the NIM (serial or Ethernet):  AC Power: Standard IEC male connector.100-240 VAC (auto-sensing), 47-63 Hz  RWM port: DB-25 female connector, for attachment ofRWM-to-NIM cable. See Appendix F forsignals and pinouts.  NIM-to-NIM ports: RJ-H connectors, for synchronization amongmultiple co-located NIM units.For the WISL system with serial interface, there is an additional connector:  Serial port: DB-25 female, for attachment to user equipment.See Appendix D for EIA-530 signals and pinouts.For connection to Cisco routers in the followingfamilies, use Cisco cable CAB-530MT (partnumber 72-0797-01): Cisco 7000 series,4000 series, 3600 series, 2500 series,1600 series, Cisco access servers, andAccessPro cards.For the WISL system with Ethernet interface, there is an additional connector:  Ethernet port: RJ-45, for attachment to user's 10BaseT LAN.User-data port (DB-25F/EIA-530 or RJ-45/10BaseT)Wireless Modem port (DB-25F) NIM-to-NIM sync ports
Wireless Internet Service Link - User's Manual Section 2: System Description2-7 DRAFT2.2.2  Front Panel Display and IndicatorsFigure 2-7.  Front PanelFigure 2-7 shows the NIM front panel layout.  The liquid crystal display (LCD) at the rightside of the panel displays ongoing status information, and is updated automatically at1-second intervals.At the left side of the panel, six light emitting diodes (LEDs) serve as signal indicators:  USER An active connection exists between the NIM and the user's(Green LED) equipment.  For the serial NIM, this implies that the cablebetween the NIM and the user's equipment is installed, andthat the DTR (Data Terminal Ready) signal is asserted.  Forthe Ethernet NIM, the LED indicates that an active Ethernetcable is connected to the NIM.  CL For the serial NIM, this LED indicates that the NIM clocking(Red LED) signal is present. This is the signal that enables synchronoustransmission to occur.  For the Ethernet NIM, this LED flasheswhenever a collision is detected.  TX This LED is on whenever the user's equipment is transmitting(Yellow) data to the NIM.  RX This LED is on whenever the NIM is forwarding the data it has(Yellow) received from the RWM, to the user's equipment.  ARQ The ARQ LED flashes at the receiving end of a link when a(Red) packet error is detected.  LCK This LED has a dual function.  It flashes red while the(Red/Green) RadioWire modems at the two ends of the link are attemptingto synchronize with one another. Once synchronized, the LEDchanges to a solid green display, indicating that the two endsare locked.For initial configuration or re-configuration of the WISL system, the front panel of the NIMunit may be removed to provide access to the Console port.  The port comprises a femaleDE-9 connector, to which either a PC-compatible computer or a dumb terminal may beattached.  The cable required is a 9-pin straight-through male-to-female serial cable.  A6-foot cable of this type is included in the System Installation Kit available separately fromRadioConnect (part number 004-0001-00).  Such cables are also readily available at mostcomputer stores.Signal indicators Status displayConsole port (DE-9F)  -  remove front panel for accessUSER         CL          TX         RX       ARQ       LCK
Wireless Internet Service Link - User's Manual Section 2: System Description2-8 DRAFT2.2.3 Synchronization CableOne synchronization cable is provided with each WISL system. This 12" cable is used toconnect two NIM units together via the sync ports (RJ-H connectors) on the rear panel. Morethan two NIMs may be interconnected by daisy-chaining them together, as shown inFigure 2-8.  Note that the two connectors on each unit are functionally identical, so thateither cable may be plugged into either socket.Figure 2-8.  NIM Units 'Daisy-Chained' for SynchronizationThe purpose of interconnecting units in this way is to provide a clock signal between themthat causes all units to synchronize their transmit and receive cycles. The clock signal isprovided by a single NIM configured as the 'primary' unit.  The effect of this interconnectionis that all units transmit in the same cycle, and then receive in the same cycle, which avoidsthe possibility of some of the co-located units receiving the transmissions of others.
Wireless Internet Service Link - User's Manual Section 4: Operation3-1 DRAFT3 Installation3.1 System Installation KitRadioConnect offers a System Installation Kit (part number 004-0001-00) which may bepurchased separately from your WISL systems.  Although not pre-requisite for installing alink, the kit is recommended.  It is re-usable for installing multiple links, and contains thefollowing items:  3-foot RWM-to-NIM cable, required if units are to be configured prior to installation  6-foot Console cable RF emulation cable  Cable pull grip  Cable assembly/continuity tester for RWM-to-NIM cable (comprises 2 components– loop-back terminator for RWM end of cable, and display terminator for NIM end.)  Tools:  Allen key, screwdriver and wrench Magnetic compassIn addition to these items, the person installing the link may also need a steel-tape cablepuller (also referred to as a "snake"), and some nylon cable ties.  A cable tie will be used toattach the cable pull grip to the cable puller, as explained in Section 3.6.1 below.3.2 Installation ProcedureFigure 3-1 shows a high level flowchart of the required and optional steps for installing alink.  The WISL equipment can be installed without requiring initial configuration.  However,this is not recommended, as it is much easier to configure and test both units together at asingle location, before they are transferred to their eventual (remote) sites.In either case, at least one configuration parameter must be set before the two WISLsystems can communicate. That parameter is the ‘Master/Slave Status’ (Section 3.4.3). Untilone end of the link is set as Master, and the other end as Slave, installed units cannot bealigned.CAUTIONIf you are not familiar with working on towers and antennas,get help from an experienced installer.  Installing towerstructures and mounting antennas can be dangerous andlife threatening.  Make sure the tower or pole you are usingis of appropriate size to carry the weight and wind load ofthe RadioWire Modem and antenna system.

Wireless Internet Service Link - User's Manual Section 4: Operation3-3 DRAFT3.3  Configuring Your SystemThe first step towards configuring each of your WISL systems is to complete the linkConfiguration Worksheet (Appendix C).  Refer to the System Overview and Planning Manual(part number 950-0001-00) for guidance in preparing the Worksheet.  There are severalimportant parameters that must be configured correctly for proper operation:1)  Pseudo-random spreading code2) Frequency channel3) Master/Slave status4) Synchronization generator status5)  Transmit power control mode and levelEach of these parameters is discussed in detail below, and a completed Worksheet exampleis shown in Figure 3-8.Next, take the following steps in preparation for configuring each unit:  If the configuration process is being carried out before a WISL system has beeninstalled, connect the RWM and NIM together using the 3-foot cable provided in theSystem Installation Kit.  If the configuration process is being carried out after installation, the RWM and NIM arealready connected.  Connect a personal computer (PC) to the NIM console port (section 2.2.2) using astandard serial cable (9-pin, straight through, male-to-female). One such cable isprovided in the System Installation kit.  Power up the PC and install the Configuration Utility from the 2-disk set provided withyour WISL system.  The PC must be running Windows 95 or later, or Windows NT.Insert disk 1 into the floppy drive, and display its contents under Windows Explorer.Double click on the file 'setup.exe', then simply follow the on-screen instructions tocomplete the installation.  Power up the NIM, then load the Configuration Utility by double clicking its icon.  Thefollowing window will open:Figure 3-2.  Configuration Utility - Port Selection ScreenSelect the COM port to which the NIM is attached, then click the 'Continue' button.

Wireless Internet Service Link - User's Manual Section 4: Operation3-5 DRAFT3.4  Radio Configuration Parameters3.4.1 Frequency ChannelThe RadioWire Modem supports three discrete, non-overlapping frequency channels withinthe 2.4 GHz band allocated for unlicensed use.  These are shown in the ConfigurationWorksheet as channels 1, 3 and 5.  The other two channels (2 and 4) partially overlap theirneighbors. In general, use channels 1, 3 or 5 only, unless you are co-locating more thanthree RWM units at the same site.  Select the desired channel from the pull-down menu.3.4.2 Master/Slave StatusOne unit on each point-to-point link must be configured as the link Master. The other unitmust be the link Slave.  The link Master controls transmit and receive timing for a given link.When multiple RWM units are co-located, they will typically all be specified as Masters(Figure 3-5).  However, if a hierarchical network is being built, similar to that shown inFigure 3-6, all nodes except the central one will have at least one Slave coupled to one ormore subsidiary Masters through appropriate user equipment such as an Ethernet hub or aserial synchronous time-division multiplexer (TDM).  Click on the appropriate button to selectMaster or Slave status.Figure 3-5.  Master/Slave Assignments in a Star NetworkAll central unitsare ‘Masters’‘Slave’‘Slave’‘Slave’‘Slave’‘Slave’
Wireless Internet Service Link - User's Manual Section 4: Operation3-6 DRAFTFigure 3-6.  Master/Slave Assignments in a Hierarchical Network3.4.3 Synchronization GeneratorWhen multiple RWMs are co-located at a site, they must be synchronized to all transmit atthe same time and all receive at the same time, to help avoid mutual interference.  Toaccomplish this, every RWM is equipped with the ability to generate a synchronous clocksignal.  However, only one unit can be the active synchronization generator at any giventime, and all other co-located units must receive the synchronization signal through the‘daisy-chain’ of cables that couple their NIMs together.A special requirement applies at all subsidiary nodes of a hierarchical network.  At all suchnodes, only Slave units may take the role of synchronization generators. This is because aSlave unit derives its clock from the airwave signal it receives from its associated Master.This requirement ensures that the entire network operates coherently from a single clocksource.  The example in Figure 3-7 illustrates this.  Click on Sync Generator, if required.3.4.4  Transmit Power LevelThe transmit power level may be set between a minimum of -2dB and a maximum of +24dB.When shipped, the default setting is 0dB.  If a unit is being configured prior to installation,care should be taken with regard to increasing the power level.  Excessive power levels canbe hazardous to humans, as well as to other operating radio equipment in the near vicinity.If possible, setting of the power level should be left until the link is being installed.  In theU.S.A., the maximum power level of +24dB is only required when operating at the maximumrange specified for the antennas.  Some countries require a lower maximum transmit powerlevel than the +24dB permitted in the U.S.A.All central unitsare ‘Masters’‘Slave’‘Slave’‘Slave’‘Slave’‘Masters’‘Slave’‘Slave’‘Masters’‘Slave’‘Slave’‘Masters’‘Slave’‘Slave’

Wireless Internet Service Link - User's Manual Section 4: Operation3-10 DRAFT3.6 Pre-Installation TestingTo ensure satisfactory operation between two WISL systems, they may be tested togetherbefore being transferred to their eventual destinations.  For testing in close proximity, the RFemulation cable supplied in the System Installation kit must be used.The procedure for pre-installation testing is as follows:1)  After configuring each of the two WISL systems, disconnect power to both of them.2)  Carefully remove each RWM from its antenna using the Allen key supplied in the SystemInstallation kit.  Set aside the antennas for later re-attachment.3)  Place the two RWM units on a flat surface about 2-3 feet apart, with their antennasockets uppermost.  Connect the RF emulation cable between the two sockets.4)  Connect each RWM to its NIM (if not already connected), using the 3-foot cablessupplied in the System Installation kit.5)  Power up both systems.  Within about 20 seconds, the green LED on each RWM shouldturn on solidly and the red LED should be off.  In addition, the ‘Lock’ (LCK) indicator onthe NIM front panels should both be on (green), and the ‘Error’ (ARQ) indicator shouldbe off. If this is the situation, the two WISL systems are communicating satisfactorily,and you can move on to step 6). Otherwise, refer to ‘Troubleshooting’ (Section 3.5.1)below.6)  This step is optional.  If you have the necessary equipment available for transferring userdata across the link, make the necessary connections to the two NIMs, and ensure thatdata transfer is working correctly.  If not, refer to ‘Troubleshooting’ (Section 3.5.1) below.CAUTIONDo not under any circumstances attempt to test twoRadioWire Modems in close proximity, with theirantennas installed.  To do so may result in severedamage to both units, due to excessive signal loadon the receivers. Two units equipped with +14dBi helicalantennas may not work satisfactorily at anydistance less than 130 meters. Two units equipped with +24dBi helicalantennas may not work satisfactorily at anydistance less than 1.3 kilometers.
Wireless Internet Service Link - User's Manual Section 4: Operation3-11 DRAFT3.7  Installing the RadioWire ModemThis procedure assumes that suitable locations have been selected for installation of theequipment at both ends of the link, and that poles or towers are available on which to mountthe RadioWire Modems.  It also assumes that during the pre-installation survey, a suitableroute was determined for running the serial cable down from the RWM to the NIM, at eachend of the link.Take the following items up to the roof area where the RWM is to be installed: RadioWire Modem  Antenna and its assembly fasteners  Mounting bracket and assembly fastenersAlso, the following items from the System Installation kit (or suitable equivalents):  Cable pull grip  Loop-back terminator for RWM end of cable (a component of the cableassembly/continuity tester for the RWM-to-NIM cable)  Allen key, screwdriver and wrench Compass3.7.1  Attaching the RWM and Antenna to the PoleWith all the necessary equipment gathered at the mounting site, the next step is to install themounting bracket assembly.  Figure 3-9 shows how this is done.  Position the bracket sothat it is facing approximately in the direction of the remote site, and is at the desired heighton the pole.  Use the compass provided in the System Installation kit to set the azimuth, ifthe remote location is too distant to be seen with the naked eye. Note that the azimuthvalues of one site with respect to the other were entered on the Configuration Worksheetduring the link-planning phase.  Tighten the mounting bolts enough to allow the bracket tobear the weight of the modem and antenna.The next activity depends on which antenna you are using. In the case of the 1-meterantenna, it must first be assembled.  Attach the 3 legs to the main dish, using the bolts,washers and nuts provided, and then attach the modem-mounting plate to the legs (seeFigure 3-10).  The other two antennas do not require assembly.Now attach the RadioWire Modem to the antenna, using the four knurled Allen screwsprovided.  Refer to Figures 2-3 through 2-5 for the way in which the two parts fit together.CAUTIONFor compliance with safety regulations, theRadioWire Modem must be grounded toearth.  It is recommended that a metal polebe used for mounting the RWM, and thatthe pole itself has a substantial connectionto an earth grounding system.
Wireless Internet Service Link - User's Manual Section 4: Operation3-12 DRAFTAttach the combined RWM/antenna assembly to the mounting bracket on the pole. Onceagain, the method of attachment for the 1-meter antenna is different than for the other twoantennas.  (*** 1-meter antenna TBD ***).For the two smaller antennas, it is the RWM that attaches to the mounting bracket.  On therear of the RWM enclosure, there is a metal strip that serves as a hook. It allows the RWMto be hung on the mounting bracket in the correct position for the large knurled fasteners tobe screwed into the RWM (Figure 3-9).  This hook-and-lip system makes it possible tocomplete attachment of the RWM/antenna assembly using only a single hand, which maybe necessary in situations where you need to use your second hand for support.Later on, elevation and azimuth adjustments will be made via the mounting bracket, in orderto align the RWM units at the two ends of the link. But for the moment, the next step is toinstall the cable from the roof down to the NIM location. Begin by securely connecting thecable to the RWM. This will anchor the upper end of the cable while the other end is beingpulled down.

Wireless Internet Service Link - User's Manual Section 4: Operation3-14 DRAFT3.7.2 Cable InstallationAt this point, you must determine whether a cable puller tool will be needed.  For example, ifthe cable will be run external to the building walls, the tool will probably not be needed(Figure 3-11).  Similarly, if a clear vertical path is available within the wall cavity, the cablecan be installed without the need for a puller.However, cable routing is typically not as straightforward as shown here.  Often, obstacleswithin the wall cavities must be circumvented, or the cable must travel through acombination of wall and floor cavities. In these cases, use a cable puller, starting from theNIM location and working the steel tape up to the roof.Next, return to the roof, and slide the cable pull grip fully over the open end of the cable,ensuring that no slippage occurs once the grip is in place (Figure 3-12).  Now connect theloops at the ends of the cable pull grip and the steel tape, using a nylon tie wrap threadedthrough them both.  Trim the free end of the tie wrap, so that it will not catch on anything asit passes through wall and/or floor cavities.Return to the NIM location, and proceed to carefully reel-in the steel tape until the cablereaches you.  During this procedure, it may be useful or necessary to have the assistance ofa second person on the roof to feed the cable, ensuring that it does not get tangled.You are now ready to install the DB-25 connector on the NIM end of the cable.  Remove thecable pull grip from the cable end, by pushing it off from its open end.  This compresses themesh, thus releasing its friction grip on the cable and allowing it to slide off.RadioWire ModemNetwork InterfaceModuleRoofCable entrythrough wallPoleRadioWire ModemNetwork InterfaceModuleRoofCable entrythrough roofPoleCable routedin wall cavityFigure 3-11.

Wireless Internet Service Link - User's Manual Section 4: Operation3-15 DRAFTSeparate the two halves of the DB-25connector shell and remove the main body(see Figure 3-13).  Using the pin-outinformation provided in Appendix F,carefully insert the pins into the numberedholes, from the rear of the main body.Ensure that all pins are fully seated andprotrude from the connector an equalamount. Clamp the two shell halves backover the cable and main body assembly,ensuring that the braided grounding sheathof the cable makes full contact with theshell halves at the cable-entry collar. Insertand tighten the screw that holds the twohalves together.At this point you may optionally test thecomplete cable for correct assembly and leadcontinuity, using the tester provided in theSystem Installation kit.  To do so, go up to theroof, disconnect the cable from the RWM, andinstall the loop-back terminator on the cableconnector.  Return to the NIM location andinstall the display terminator component of thetester.(**** Add tester operating procedure ****)After removing the test terminators, reconnectthe cable to the RWM.3.8  Installing the Network Interface ModuleThe Network Interface Module must be located in the vicinity of the user equipment to whichit will be connected.  It may either be installed as a freestanding unit on a suitable surfacesuch as a shelf, or a pair of NIM units may be attached side-by-side and rack-mounted in astandard 19" rack.  A special RadioConnect Universal Rack-Mount kit (Figure 3-14) isavailable from your reseller for this purpose (part number 250-0001-00).If multiple WISL systems are being installed at the same location, they must be inter-connected using the synchronization cables provided.  Refer to Section 2.2.3 for details ofhow to "daisy-chain" multiple NIM units together.After physically installing the NIM unit(s), connect the cable from the RWM, to theappropriate DB-25 socket on the rear panel.Figure 3-12.

Wireless Internet Service Link - User's Manual Section 4: Operation3-16 DRAFT3.8.1 Electrical RequirementsThe system is now ready to be powered up. Connect the power cord to the NIM. Forcompliance with safety regulations, the NIM must be connected to a properly groundedelectrical circuit.The foregoing procedure for mounting the RadioWire Modem and antenna, installing theRWM-to-NIM cable, and installing the Network Interface Module, must next be repeated forthe WISL system at the other end of the link.  Once this has been done, you are ready toproceed with alignment of the systems.3.9  Antenna Alignment ProcedureWith power applied to both WISL systems, return again to the roof at one end of the link.Inspect the LEDs on the underside of the RadioWire Modem. If the green LED is on solidly,and the red LED is off (i.e. not flashing), no further adjustment is needed.  Simply tighten allbolts and fasteners as much as possible, using the tools provided.If the status of the LEDs is not as required, carefully loosen the mounting bracket bolts justenough to be able to rotate the Modem around the pole.  Be sure that while you do this, yousupport the unit so that it does not slide down the pole.  Next, adjust the azimuth in smallincrements to the left or right, until the optimum LED status is achieved.  If it is not possibleto find an ideal position at which the green LED is on solidly and the red LED is fully off, thenthe best position is that at which the flashing of the red LED is minimized.  Once this isaccomplished, tighten the mounting bracket bolts as much as possible.You may also try optimizing the LED status by adjusting the elevation angle of the RWM.Do this by loosening the vertical tilt bolts on the mounting bracket, then tilting the unit up ordown in small increments.Once the best possible combination of red and green LED status is achieved, tighten allbolts and fasteners as much as possible.Repeat this alignment procedure at the other end of the link.3.10  Connecting to User’s EquipmentThe final step in installing your Wireless Internet Service Link is to connect the NIM at eachend of the link to its associated user equipment.
