viN2-X Ethernet Extender Installation and Operation ManualWelcome!Welcome to the Wireless, Inc. N2-ACCESSTM Series product family. This manual is designedto introduce you to the N2-X Ethernet ExtenderTM, and to provide you with information necessaryto plan, install, operate and maintain a N2-X Ethernet Extender wireless communicationsystem.The N2-X Ethernet Extender is intended for professional installation only. This manual,however, is also designed for personnel who plan, operate and administrate the N2-X EthernetExtender communication system. Please review the entire manual before powering up ordeploying any N2-X Ethernet Extender.Updates to this manual will be posted on the Wireless, Inc. Customer Service Website athttp://www.wire-less-inc.com. Registered Wireless customers can access Wireless’ on-lineinformation and support service, available 24 hours a day, 7 days a week. Our on-line serviceprovides users with a wealth of up-to-date information, with documents being added or updatedeach month.Radiation WarningsMicrowave Radio Radiation WarningUnder normal operating conditions, N2-X Ethernet Extender radio equipment complies with thelimits for human exposure to radio frequency (RF) fields adopted by the Federal Communica-tions Commission (FCC). All Wireless, Inc. microwave radio equipment is designed so thatunder normal working conditions, microwave radiation directly from the radio is negligible whencompared with the permissible limit of continuous daily exposure recommended in the UnitedStates by ANSI/IEEE C95.1-1991 (R1997), Safety Levels with Respect to Human Exposure toRadio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.Microwave signal levels that give rise to hazardous radiation levels can exist within transmitterpower amplifiers, associated RF multiplexers, and antenna systems.Never look into the open end of a Waveguide as eyes are particularly vulnerable to radiation.Do not disconnect RF coaxial connectors, open microwave units, or break down anymicrowave screening while the radio equipment is operating.
viiN2-X Ethernet Extender Installation and Operation ManualMicrowave Antenna Radiation WarningDesigned for point-to-point operation, an N2-X Ethernet Extendermicrowave radio system willuse directional antennas to transmit and receive microwave signals. These directional anten-nas are usually circular or rectangular in shape, are generally located outdoors, and are usuallymounted on a tower or mast.Referencing OET Bulletin 65 (Edition 97-01, August 1997) from the Federal CommunicationCommission’s Office of Engineering & Technology, limits for maximum permissible exposure(MPE) to microwave signals have been adopted by the FCC for both Occupational/Controlledenvironments and General Population/Uncontrolled environments. These limits are 5.0 mW/cm2 and 1.0 mW/cm 2, respectively, with averaging times of six-minutes and thirty-minutes,respectively.The closer you are to the front center-point of a microwave antenna, the greater the powerdensity of its transmitted microwave signal. Unless you are very close, however, microwaveexposure levels will fall far below the MPE limits. To determine how close to a microwaveantenna you can be and still remain below the MPE limits noted above, “worst case” predictionsof the field strength and power density levels in the vicinity of an N2-X Ethernet ExtenderTMmicrowave antenna can be made from the following calculations. The equation is generallyaccurate in the far-field of an antenna, and will over-predict power density in the near-field (i.e.close to the antenna).S = PG/4πR2where: S = power density (in mW/cm 2)P = power input to the antenna (mW)G = power gain of the antenna in the direction of interest relative to an isotropicradiatorR = distance to the center of radiation of the antenna (cm)Note that G, the power gain factor, is usually expressed in logarithmic terms (i.e., dB), and mustbe converted using the following equation:G = 10 dB/10For example, a logarithmic power gain of 24 dB is equal to a numeric gain of 251.19.Assuming (1) maximum output power from the N2-X Ethernet Extender (+3.5 dBm [2.238 mW]),(2) no signal loss in the cable connecting the N2-X Ethernet Extender to the antenna, and (3)the use of a 27 dBi gain parabolic antenna, the 5.0 mW/cm2 and 1.0 mW/cm 2 MPE power densitylimits would be reached at distances of approximately 4.22 cm and 9.44 cm, respectively.Wireless, Inc. fully supports the FCC’s adopted MPE limits, and recommends that personnelmaintain appropriate distances from the front of all directional microwave antennas. Should youhave questions about N2-X Ethernet ExtenderTM microwave signal radiation, please contact theWireless, Inc. Customer Service Department.

16N2-X Ethernet Extender Installation and Operation Manual2.6 Theory of Operation2.6.1 N2-X Ethernet Extender TransmitterThis description should be used in conjunction with the system block diagram Figure 2.4.The data signal and the AC/DC supply voltage are connected to the ODU by means of apower/data cable assembly. The supply voltage passes through a bridge rectifier to a DCto DC converter. The output of this converter is +15V. This +15V supply drives three DCregulators within the ODU.One regulator provides -5 VDC, the second 11 VDC and the third being a dual output typesupplies +5 and +5.8 volts.The FPGA coder interleaves and scrambles the TTL data from the coder. The FPGA isprogrammed to output the data at 4 times the input rate (6.176 MHz for the DS1 rate or8.192 MHz for E1 rates). This provides a data rate which is optimal with respect to the FCCrules for spectral power densities defined for this frequency allocation.The data is passed through a 7th order low pass filter to reduce unwanted high frequencysignal images prior to modulation. A double balanced mixer is used to modulate the datasignal on to a CW signal provided by the synthesizer at the desired output frequency. Theoutput of the mixer contains the BPSK modulated signal at the desired frequency.A high pass filter eliminates spurious noise, rejects harmonic images and insures that theproper bandwidth is maintained prior to being amplified.The RF output section consists of three main components: a RF driver amplifier, a logiccontrolled switch attenuator and a RF power amplifier. The driver amplifier provides the firststage of RF amplification, the switch attenuator serves a dual purpose. The first is toprovide a customer selectable 6 dB attenuator to reduce output power when needed.Secondly, this circuit acts as an RF impedance matching network between the driver andpower amplifier gain stages. The power amplifier provides the amplification required priorto being output through a diplexing filter and ultimately to the antenna.

18N2-X Ethernet Extender Installation and Operation Manual2.6.2 N2-X Ethernet Extender ReceiverThe description should be used in conjunction with the system block diagram (Figure 2.4).At the antenna, the received BPSK modulated signal from the opposite terminal is passedthrough a diplexing filter which is used to isolate the incoming signal from the transmitter outputand to bandpass filter the received signal thereby reducing the chance of unwanted signalproducts from entering the receiver. A low noise amplifier (LNA) detects and amplifies the signalbandpass filter on the output of the LNA provides band limiting of the received spectrum to rejectunwanted signal products. The first downconverter combines a CW signal at the receiverfrequency from the synthesizer and the incoming signal by means of a mixer to produce the firstIF product at 474.880 MHz. A 75 MHz bandpass filter limits the possibility of unwanted out ofband products from entering the 2nd IF. The first IF is amplified by a MMIC device and isdownconverted by mixer a 389.76 MHz signal from the synthesizer with the 474.880 MHz 1stIF signal. The result is a 85.12 MHz 2nd IF product which is bandpass filtered and fed to an RSSIIF processing DC which derives an RSSI voltage used to determine signal strength.A BPSK demodulator places the 85.12 MHz 2nd IF and 85.12 MHz varactor diode source outof phase. The resultant product is a DC level I and Q signal of which only the I signal is inputto the Bit Synchronizer to re-clock the data. The re-clocked data is decoded and output at TTLlevel to the DS1/E1 level converter which outputs the data in AMI, B8ZS or HDB3 format asneeded. The data is interconnected to the TU and output on the front panel by means of RJ-48C or BNC connector depending on the data format being used.2.6.3 SynthesizerThe FPGA provides four 22-bit streams in a serial format loaded to the synthesizer. This dataprovides all of the possible frequencies at which the system can operate. Depending upon thedip switch settings selected, the actual frequency being used is selected. When the reset buttonis pressed, the FPGA will reload this data to the synthesizer. The PROM contains all of thepossible frequency combinations.

If the LED is Off, refer to the Maintenance andTroubleshooting section of the manual.Refer to Table 3.2.3.5.1 Configuring N2-X Ethernet Extender System AntennasThe antennas used on an N2-X Ethernet Extender radio system are generally configurable foreither vertical or horizontal polarization. It is extremely important to verify that both antennasare configured for the same polarization, and that the appropriate antenna polarization hasbeen selected for the specific radio link.Table 3.2 - Installation ChecklisttsilkcehCnoitallatsnI?eruceserawdrahgnitnuomkcarehtsI?dednuorgylreporptinuehtsI?detcennocylreporpannetnaehtsI?tcerrocdnaecalpnisnoitcennocatadehterA?nODELrewoPehtsI519530LW
27N2-X Ethernet Extender Installation and Operation Manual3.5.2 Aligning the N2-X Ethernet Extender System AntennasWith the N2-X Ethernet Extender at each site properly configured for operation, antennaalignment must be performed at both sites. Proper antenna alignment is crucial to the properoperation of an N2-X Ethernet Extender radio system, and should only be accomplished byexperienced professionals.The N2-X Ethernet Extender is equipped with a ODU mounted BNC-(f) Link Test connector towhich an analog or digital voltmeter can be connected. The voltage range at the test point,between the center conductor of the connector and ground, varies from approximately two VDCto four VDC, serving as a receive signal strength indicator (RSSI). The stronger the receivesignal, the higher the RSSI voltage.Emanating from a microwave antenna is a main beam (or lobe) of RF energy, surrounded byRF side lobes. The beamwidth of the main beam varies with the size and type of antenna, aswell as the specific frequency of the RF signal, and is generally defined by the nominal total widthof the main beam at the half-power (-3 dB) points. Side lobes surround the main beam at specificangle distances, and will be lower in power than the main beam.When aligning an antenna system, it is extremely important to verify that the antennas are bothaligned on the main beam, not on a side lobe. Referencing Table 3.3, the first side lobe willgenerally be located at an angle slightly less than twice the antenna beamwidth.Following the course alignment of an antenna system, a common practice when performing afine alignment is to slowly swing each antenna (one at a time!) in both vertical (elevation) andhorizontal (azimuth) planes to verify that the main beam and first side lobe can be accuratelyidentified. This insures that accurate alignment of the antenna system on the main beam hasbeen accomplished.Each N2-X Ethernet Extender is shipped with an RSSI test sheet, showing the relationshipbetween the receive signal strength level (in dBm) and the RSSI level (in VDC). These RSSItest sheets are often referred to as AGC Curves. The RSSI test sheets can be used to verifythat the calculated receive signal levels match up with the actual receive signal levels.Substantial differences between calculated and actual levels could point to transmissionsystem problems, side lobe alignment, path obstructions, etc.Table 3.3 - Approximation TableretemaiDannetnA elytSdna )iBd(niaG htdiwmaeBBd3 )seerged(,eboLediSts1 mumixaM )seerged(,eboLediSdn2 mumixaM )seerged(cilobaraptoof-2cilobaraptoof-4619530LW

29N2-X Ethermet Extender Installation and Operation Manual4.0 Maintenance and TroubleshootingThe N2-X Ethernet Extender contains static sensitive components, and has no user-service-able parts.4.1 N2-X Ethernet Extender MaintenanceThe N2-X Ethernet Extender is designed to operate with no scheduled maintenance activities.From a precautionary perspective, a regular check of power supply input voltages and RSSIvoltages should be planned by the user.4.1.1 RSSI VoltageThe Wireless Customer Service department recommends a monthly check of the N2-XEthernet Extender’s RSSI voltage. Variations in the RSSI voltage could be an indicator ofantenna or antenna feed movement, loose or improper RF cabling or connectorization, pathobstructions or reflections, etc.
30N2-X Ethernet Extender Installation and Operation Manual4.2 Identifying and Resolving Receive Signal Strength IssuesThere are a great number of items which can affect the transmission of a microwave signal fromone site to another. Every microwave path is unique, and must be evaluated for performancebefore a radio link is installed.Outside of radio equipment issues, antenna alignment, RF signal blockage, and multipathfading are among the most common transmission problems experienced in the field.4.2.1 N2-X Ethernet Extender Equipment IssuesFrequency Selection1. Verify the transmit/receive frequency selection for each N2-X Ethernet Extender radio isset appropriately, and that a “matched pair” of radios has been selected for the system.Each N2-X Ethernet Extender terminal can be set to the frequencies listed in Table 4.1.2. To reduce the possibility of co -adjacent channel interference, proper frequency coordi-nation and antenna polarization is used to isolate each channel. The concept is to achievemaximum RF isolation between link channels by means of frequency spacing and antennapolarization. In a “star” configuration an optimum frequency and antenna polarization planis provided to demonstrate an example of maximum isolation between links (See Figure4.1).Figure 4.1 - Frequency Selection for the N2-X Ethernet Extender Radio1H 12H24H43H37V78V86V65V5H = Horizontal Antenna PolarizationV = Vertical Antenna PolarizationWL035917HHHHVVVV

Notethat the shear stop clamp used on the two foot antennas also provides the azimuthadjustment.2. Refer to Figure B.1 for the position of the antenna centerline relative to the shear stopclamp. The clamp must be mounted to provide support during installation and azimuthadjustment.Figure B.15 - Azimuth Clamp/Shear Stop Assembly3/8” (10mm)Round HeadScrew Lockwasherand Nut (4)ø 2.4” - 4.5”(60-115mm)WL035946WL035947
B-15N2-X Ethernet Extender Installation and Operation ManualAntenna Hoisting and Installation1. Attach a hoist strap around the vertical assembly or the horizontal assembly as shown inFigure B.17. Do not hoist by the elevation rod. Make sure that the vertical assembly isunobstructed where it will mount against the mast pipe.2. Attach tag lines and carefully lift the antenna into position, resting the vertical assembly onthe shear stop clamp.3. Fasten the mount to the mast pipe with 1/2” U-bolts. The antenna must be free to rotateduring azimuth adjustment, so tighten only enough to close the gap between the mast andvertical channel. Do not leave the antenna loose for any extended period of time, i.e.overnight.Figure B.17- Hoisting the AntennaWL0359485”(127mm)
B-16N2-X Ethernet Extender Installation and Operation ManualGeneral Antenna Alignment ProceduresNormally the antenna is aligned by performing azimuth and elevation adjustments andelevation adjustments as necessary until the peak signal is obtained. It may be helpful to re-peak one adjustment before finalizing or locking down the other. See Figure B.18.Warning: Damage to the antenna can occur if azimuth or elevation adjustments areattempted without loosening the proper connections as described in the following steps.Azimuth Adjustment1. Be sure the mast pipe U-bolts are just loose enough to allow mount rotation whilemaintaining complete contact between the mount and the mast pipe.2. Turn the long stainless steel azimuth screws against the mounting channel. By alternatelyturning one azimuth adjustment screw out and the other in, the antenna can be rotated tothe desired azimuth angle. Approximately 1 turn changes the azimuth direction by 1°. Avoidadjusting the antenna beyond the ±5° provided by the azimuth clamp as this can damagethe adjusting hardware. Fasten the antenna to the mast pipe and reposition the clamp ifneeded.Note: By securing the mount to the mast pipe and realigning the azimuth clamp with theantenna boresight, more reliable and precise azimuth adjustments can be achieved.After all adjustments are made, tighten both of the azimuth screws against the channel andsecure with the lock nuts provided.3. Tighten the mast pipe U-bolts while maintaining the peak signal by alternating from left toright in 1/4 turn intervals.Figure B.18 - Antenna Alignment using RSL Output while Adjusting the AntennaWL035949
B-17N2-X Ethernet Extender Installation and Operation ManualElevation Adjustment1. Insure that both of the bolts connecting the mount to the Top Support Angles and thepivoting Elevation Angle (refer to Figures B.7 and B.9) are just loose enough to allowresisted rotation. See Figure B.18.2. Back the outer nuts on the elevation rod away from the bottom mount plate to allow somefine adjustment range.3. Turn the inside nut (with flat washer) on the elevation rod to adjust the elevation angle.Approximately 5 turns changes the elevation by 1°. Remember, for elevation greater than20°, install the two beveled washers as shown in Figure B.9.4. After all adjustments are made, lock the nut against the bottom mount plate. Tighten theangle pivot bolt and support bracket bolts.Important: Be sure to tighten all hardware after final adjustments and insure that splitlockwashers, palnuts, or jam nuts are used where provided.
B-18N2-X Ethernet Extender Installation and Operation ManualTable B.3 - Nut Tightening ProceduresInspection and Maintenance1. Before leaving the installation, check that all hardware on the mount, shroud, radome, andfeed is tight and that nuts are locked in place.2. Inspection of the antenna should be performed at lease once a year to check its conditionand to insure safe operation and maintenance. Qualified personnel, knowledgeable andexperienced in antenna installations, are required for this inspection.Supplemental InformationTable B.3 is provided for installers unfamiliar with adequate nut tightening procedures for useon stainless steel bolts, U-bolts, galvanized bolts or any bolts without the ASTM-”A325” markingon the head. Disregard these recommendations when specific tightening requirements aregiven.Note: It is not recommended to reuse a palnut that has already been fully tightened ordeformed in any way. It should be replaced by a new palnut.Weather Proofing the Type N Female Connector on FeedsRemove the protective cover from the end of the feed and mate the connectors, screwing themale connector firmly onto the feed.Important: After connecting the coaxial cable, wrap the Type N connector with the gray butylrubber, squeezing it firmly around all joints to make a continuous seal. Finish theweatherproofing by wrapping the butyl rubber with several layers of black PVC tape (notsupplied).eziStloBlanimoNeuqroTtuNeuqroTtunkcoLtunlaP"4/1.bl/.ni05.bl/.ni04"61/5.bl/.ni201.bl/.ni06"8/3.bl/.tf51.bl/.ni58"61/7 .bl/.tf42 .bl/.tf51"2/1.bl/.tf73.bl/.tf61"8/5.bl/.tf47.bl/.tf82"4/3.bl/.tf571.bl/.tf44"8/7.bl/.tf212.bl/.tf15"1.bl/.tf813.bl/.tf95059530LW
