lIf the R450 RM DC is offline, this indicates that they power, powersupply, CPU, or backhaul modem may not be functioning.lSome sites are configured so that an operator can log on theR450 RM DC remotely and look at the logs and watch the systemactivity. If the R450 RM DC is offline but it is still possible to logon the system, this indicates that the computer and backhaulmodem are both functional.Initial Site ActivitieslOpen the R450 RM DC and inspect the equipment.lMake sure that there is no obvious physical damage to the system,such as evidence of burned components or wires, which mayindicate a lightning strike. If there is any evidence of physicaldamage, the R450 RM DC should be replaced with the spare andreturned to Neptune's repair facility.CAUTION: The ground wrist strap must be clipped to thebox. Do not touch the computer circuit board or any of thecomponents if you are not wearing the wrist strap. Failure touse the strap could cause damage to the computer due tostatic electricity.Checking the General Health of Each of the ModulesVisual Check of CPU Board PowerThere are three Ethernet Status Light Emitting Diodes (LEDs) to theleft of the Ethernet RJ45 connector. The red LED closest to theconnector should be lit if there is power being supplied to the CPUboard. See Figure 36.Figure 36 – Ethernet Status LEDR450 Rack Mount DC Installation and Maintenance Guide 47Chapter 5: Troubleshooting
Visual Check of Radio PowerThe radio has several indicator LEDs on the front panel. The greenPower indicator should be on. See Figure 37. If the amber ALM LEDis on, the radio is malfunctioning.Figure 37 – Radio LEDs on Front PanelVisual Check of Backhaul Modem Power and ConnectivityCal Amp Vanguard ModemLook at the indicator lights on the modem to verify if the modem isworking.

This is especially true of the CPUand modem voltage checks. With no load on the power supply,erroneous values may be measured.Verify Main PowerUsually, it is a good practice to check the main power and make sureit is within specification. If there are no power indications on in theR450 RM DC, this must be checked.lThe circuit breaker should be in the ONposition. Verify that it hasnot tripped.lUsing the voltmeter, verify that there is 120V AC on both the ACfeed and the power supply sides of the circuit breaker.R450 Rack Mount DC Installation and Maintenance Guide 49Chapter 5: Troubleshooting
lIf voltage is not present on the AC feed side of the circuit breakeror is less than 110V, there is something wrong with the supplyvoltage. Repairing this is outside of the scope of this manualThe R450 RM DC is capable of functioning on voltages as low as90V.lIf voltage is not present on the power supply side of the circuitbreaker and the circuit breaker is not tripped, the breaker isdamaged. If the circuit breaker is damaged, it is recommended thatthe R450 RM DC be returned for repair.Verifying CPU Board PowerNeptune recommends checking the voltage levels going to thecomputer.1. Put on your wrist strap and attach the alligator clip to the cabinet.2. Turn off the circuit breaker.3. Remove the 10-pin connector located in the upper left corner ofthe CPU Board. There is a locking tab on the bottom side of theconnector.4. Turn the circuit breaker back on.Figure 39 – Red and Black Leads50 R450 Rack Mount DC Installation and Maintenance GuideChapter 5: Troubleshooting
5. Use the Digital Volt-Ohm-Multimeter to measure the voltage. Thered leads are positive; the black leads are negative.6. The voltage must be between 4.9V and 5.2V. Turn off theR450 RM DC circuit breaker.If the voltage is above or below these values, it indicates that thepower supply is defective. Return the R450 RM DC to Neptune'srepair facility.7. Reconnect CPU power.Verifying Radio Power1. Turn off the circuit breaker if it is not already off.2. Remove the BATT connector on the radio. The locking ringunscrews.3. Turn the circuit breaker back on.4. On the power cable connector, measure the voltage across pins Xand Y as shown.5. The voltage should be between 14.5V and 15.5V. If the voltage isabove or below these values, the power supply is defective and theR450 RM DC should be returned to Neptune's repair facility.6. If the voltage is within specifications, turn the circuit breaker offand replace the connector. Make sure that the connector lockingring is finger tight.Verifying Cellular Modem PowerCal Amp Vanguard ModemApproximately 12.0 V should be present between the two pins shownas illustrated in the following figure.Figure 40 – Vanguard Three WiresR450 Rack Mount DC Installation and Maintenance Guide 51Chapter 5: Troubleshooting
Verifying Cellular Modem ConnectivityCal Amp Vanguard ModemTo verify connectivity and signal levels, complete the following.1. Locate the RSSI LED light on the modem.2. Identify how the light is lit.lSolid = indicates signal strength is stronglBlinking = indicates signal strength is mediumlOff = indicates signal strength is poor or no signal at allFigure 41 – CalAmp Vanguard Modem with RSSI LED3. If the signal strength is poor or if there is no signal at all, there issomething wrong with the antenna, or it is possible that the localcell service is not working.For more detailed information on your wireless connection status,connect to the modems configuration application. Refer to"Securing the R450 RM DC" on page 27.EthernetIf Ethernet backhaul is used, then check the status lights on the CPUboard. Refer to "Testing the Connections" on page24.52 R450 Rack Mount DC Installation and Maintenance GuideChapter 5: Troubleshooting
Verifying Radio Functionality Using an MIUTo verify that the system is functioning properly, complete thefollowing steps.For this test to be valid, there must be regular time beacontransmissions sent by the R450 RM DC. This is indicated by theTX indicator flashing every ten seconds. See Figure 37 on page48. If the R450 RM DCis not sending out time beacons, this testwill automatically fail.1. Obtain a magnet and an MIU.2. Swipe the MIU with a magnet so that it will send out aconfiguration packet.3. Watch for the radio's Busy light to turn on. This should happenwithin a minute of swiping the MIU.lIf the Busy light turns on, it should be followed by animmediate flash of the TX indicator. See Figure 41 on page 52.lIf the Busy indicator is not immediately followed by a flash ofthe TX indicator, then there is an internal problem with theR450 RM DC that may include its configuration, the radio,NTG modem, or the computer.R450 RM DC is Syncing but Not Supplying MIU DataIf the R450 RM DC is online, this indicates that the computer and thebackhaul modem are both working. If no readings are being collectedby the R450 RM DC, this indicates that there is a potential problemwith the radio and modem.Troubleshooting this problem requires going to the R450 RM DCsite.Initial ObservationsAfter opening the cabinet, assess the following.lThe R450 RM DC sends out a time beacon every 10 seconds. Thetransmit light on the radio should flash every 10 seconds. SeeFigure 37 on page 48. Only the red transmit light should turn on. Ifthe amber ALM indicator turns on at the same time, this indicatesthat there is a problem between the transmitter and the antenna.lIf the transmit indicator does not flash, this indicates that there is apotential problem with the modem or possibly the computer's serialport.R450 Rack Mount DC Installation and Maintenance Guide 53Chapter 5: Troubleshooting
Transmitter Transmits but ALM Indicator FlashesThis requires measuring the Voltage Standing Wave Ratio of theantenna system. If the VSWR is greater than 1.5:1, that indicates thatthere is a problem with the feed line or the antenna.Measuring the VSWRTo measure the VSWR (MFJ-269 SWR Analyzer), complete thefollowing steps.1. Make sure the red Power button is off. The red button is extendedoutward.2. Press the UHF button to be sure it is extended outward.3. Turn the Frequency knob fully counter-clockwise. This knobpoints to 114-170/UHF.4. Connect the 2-inch long attenuator pad to the AntennaConnector. Leave the other end open.5. Press and lock the red Power button and the black UHF button.6. Adjust the Tune knob for desired frequencies. Sweep the entire450 - 470 MHz range.7. Observe the indicated VSWR. It should read 3.0 ± 0.2This indicates that the unit is calibrated correctly and the batteriesare good.lIf the reading is outside this range, then try replacing thebatteries (eight AA batteries).lIf this does not improve the readings, the unit needs to berecalibrated.8. Power off the unit.9. Remove the attenuator pad and connect the antenna from thebottom of the collector.10. Press and lock the red Power button and the black UHF button.11. Adjust the Tune knob for desired frequencies. Look at both thecollector receive and transmit frequencies.12. Observe the indicated VSWR. The value should be 1.5 or less.A value of 1.0 is ideal but not practical. Usually values are 1.1 or1.2.If a flashing SLP indication appears in the bottom-right corner ofthe display, this indicates Sleep mode. Simply turn the unit off andthen on again.54 R450 Rack Mount DC Installation and Maintenance GuideChapter 5: Troubleshooting
13. When finished, power off the unit.The Radio Never TransmitsThe simplest test is to cycle power on the R450 RM DC to see if theradio starts transmitting.It can take up to 10 minutes for the R450 RM DC to be fullyfunctional.lIf radio starts transmitting, this indicates that there was a soft failurein one of the serial ports possibly related to the side effects of astorm.lIf this does not fix the problem, then the R450 RM DC has aninternal problem, either with the computer or the Neptune modem.It is recommended that you return the R450 RM DC for repair.Reduction in Amount of Data CollectedIf the R450 RM DC is not collecting as much data as before, but it isstill collecting some MIU data, this usually indicates that there is aproblem with the antenna and feedline system or possibly an internalproblem. To determine the cause of the problem, complete thefollowing steps.1. Check all the system voltages as outlined above.2. Check the VSWR of the system using the technique previouslydescribed.If the VSWR is high, the feedline and antenna should be checkedout and certified by qualified radio personnel.3. Check the VSWR again, if the power output is low, by placing thewattmeter between the duplexer and the surge protector.If the VSWR measures much higher before the surge suppressor,the suppressor may be damaged.If the above tests pass, most likely there is s problem with theduplexer or radio, and it is recommended that you contact CustomerSupportR450 Rack Mount DC Installation and Maintenance Guide 55Chapter 5: Troubleshooting

R450 Rack Mount DC Installation and Maintenance Guide 57Appendix A: RF Antenna InstallationRF Antenna OverviewThere are a number of critical items you must consider when placing and installing theantenna. The following list contains items that can influence the antenna placement andinstallation.Mounting the AntennaConsider the following when mounting the antenna.1. Mount the antenna as high as possible with an unobstructed view of the coveragearea.lThe supporting structure, if the antenna is not mounted above it, can causespecific areas of limited coverage.lWater towers in particular can severely limit coverage where the signal must passdirectly through the tank. When mounting the antenna on a water tower, it isrecommended that they be mounted on top as close to the center as possible.lWhen mounting the antenna on a traditional three-leg or four-leg tower, thestandoff mount for the antenna must position the antenna at least five feet awayfrom the tower to minimize coverage area problems.2. Avoid making the R450 Data Collector's (R450 RM DC) antenna the tallest pointin the surrounding area. This may be unavoidable but it increases the potential ofthe antenna being damaged by lightning.Mounting the Antenna MastConsider the following.CAUTION: The antenna mast and stand must be groundedto the same grounding electrode used for the building'selectrical system to ensure that all exposed, non-current-carrying metal parts are the same potential. Refer to NECArticle 810.When mounting the antennas and antenna mast, it is important tomaximize the line-of-sight relationship between the RF 450 MHzAntenna and R450 MIUs for optimum RF communications.
WARNING: Antenna contact with high voltage wires mayresult in death. Watch for overhead electric power lineswhen erecting the antenna and mast.WARNING: Do not mount antennas on utility poles, electricservice masts, or other structures carrying electric light orpower wires. Coaxial cables must maintain clearance of atlease 2 feet (.61 M) from power or light wires of less than250V, or at least 10 feet (3.048 M) from power wires of morethan 250V, per N.E.C., Article 810, C.E.C. Section 54.Site RecommendationsThe following are recommendations for sites with multiple transmitters, receivers, andantennas. These sites require extra care when determining a location to install theantenna.lAvoid mounting the R450 RM DC antenna so that it is at the same height asanother antenna on the site, regardless of the frequencies.lFor sites that have multiple antennas, if possible, mount the antennas one above theother, separating each by at least 10 feet vertically. This will minimize theinterference between the systems.lThe exception to the previous rule is for cellular antennas. As long as theR450 RM DC antenna is either above, below, or in the middle of the ring of cellantennas, the two systems can coexist without interference.lAntenna sites that must share space with multiple transmitting systems may requireadditional equipment to protect the systems from interfering with each other. Thesesites may also require additional engineering to make them perform well.58 R450 Rack Mount DC Installation and Maintenance GuideAppendix A: RF Antenna Installation
lIf there are radio systems at the site that are already operating onthe 450 - 470 MHz band, it may be advantageous to combine thesignals into one antenna system using the appropriate equipment.This often works better than attempting to protect the individualsystems from interfering with each other.lManaged antenna sites may require additional equipment and maydictate how an installation is to be performed. As long as theinstallation meets Neptune's minimum requirements, following thesite's requirements is recommended.Feed Line and Antenna RecommendationsCAUTION: Neptune recommends that you consult with aqualified installer on the design and installation of theantenna systems. If the installer is already familiar with thesites and the existing equipment, this can make theinstallation go more smoothly.Feed LineThe feed line is a significant contributor to both good and poor systemperformance. A properly installed feed line is critical to optimalsystem performance. Testing the antenna while it is on the ground canensure the system is working properly.Installation of the connectors is best done with the proper tools and atrained installer. With the proper tools and jigs, installing coaxial(coax) connectors takes only a few minutes each. Not using the propertools as recommended by the manufacturer could potentially causeproblems, either immediately or after several years of apparently properoperation.Feed Line RequirementsConsider the following.lThe antenna and feed line system installation must be certified bythe installer after it is completed to perform according tospecifications.lMaximum loss for the feed line and connectors must be lessthan 3 dB.lThe feed line must be bonded at the top of the tower and at thebase of the tower. Andrew grounding kits and procedures should beused for all bonds.R450 Rack Mount DC Installation and Maintenance Guide 59Appendix A: RF Antenna Installation
lFor towers over 150 feet tall, the feed line should be bonded atregular intervals down the tower. The general recommendation isthat the feed line be bounded by a minimum of 200 feet. Siterequirements and standard practices should dictate theconfiguration.lAn optional surge protector may be installed on the tower near theantenna to help protect the feed line but is not required.lFor the AVA5-50 cable or larger, jumpers should be used to gobetween the larger cable and the R450 RM DC and antennaconnectors.lAndrew provides installation instructions for Heliax Coaxial Cable.See Bulletin 17800B Revision C. Neptune can supply a PDF copyby request through Customer Support.Cable GuidelinesPrepare the cable for installation and check for damage. You will needthe following materials to install the cable.Action Material NeededHoisting the Cable lHoist lineslPulleyslCable reellHoisting gripsAnchoring Cable lCable hangers (standard, snap-in)l3 to 4 ft. intervalsGrounding Coax ground kits (top, bottom, building entrance)Horizontal Cable Runs lAbove ground - ice bridgelBuried cable - conduit or sand below the frost line or one meterCable Connections lConnector installation instructionslConnector torquelWeatherizing kitsMeasurements lReturn Loss (VSWR)lDistance to Fault (DTF)Table 10 – Material Needed for Cable Installation60 R450 Rack Mount DC Installation and Maintenance GuideAppendix A: RF Antenna Installation

The feedline should be attached after the antenna is in place.lThere have been reports of damage to the antenna's N connectorwhere the center pin has become bent and shorts out the antennasystem. Care must be taken not to damage the connector.62 R450 Rack Mount DC Installation and Maintenance GuideAppendix A: RF Antenna Installation
System CertificationThe Andrews antenna supplied with the R450 RM DC is specified ashaving a VSWR of 1.5:1 or better over the 450 - 470 MHz range.Measuring VSWR at the R450 RM DC must take into account lossesin the feed line. For instructions, see “Measuring the VSWR” on page68. The easiest approach is to use return loss instead of VSWR. The1.5:1 VSWR translates into a return loss of 13.98dB. Refer to Table 13below, Table 14 on the next pageand Table 16 on page70 to assistwith the calculation.It is recommended that the feed line be certified as a separate step.This is best performed by putting a known amount of power into oneend of the cable and verifying that, after correcting for the cablelosses, the correct amount of power is coming out the other end.Power MeasurementInput Power1W 5W 10WReflected Power Reading Return Loss VSWR0.001 0.005 0.01 30.0 1.070.002 0.010 0.02 27.0 1.090.003 0.015 0.03 25.2 1.120.004 0.020 0.04 24.0 1.140.005 0.025 0.05 23.0 1.150.006 0.030 0.06 22.2 1.170.007 0.035 0.07 21.5 1.180.008 0.040 0.08 21.0 1.200.009 0.045 0.09 20.5 1.210.010 0.050 0.10 20.0 1.220.020 0.100 0.20 17.0 1.330.030 0.150 0.30 15.2 1.420.040 0.200 0.40 14.0 1.500.050 0.250 0.50 13.0 1.58Table 13 – Power Measurement to Return Loss andVSWR Conversion Table -Part IR450 Rack Mount DC Installation and Maintenance Guide 63Appendix A: RF Antenna Installation

VSWRCalculationNeptune recommends the following method of computing VSWR.Taking the reading at the R450 RM DC end of the feed line withoutcompensating for cabling losses may give a false impression of theantenna and feed line performance.Using a Wattmeter and a Handheld 450MHz RadioThe recommended procedure is to use a handheld commercial gradetransceiver that is tuned to the R450 RM DC's transmitter frequencyand an inline wattmeter, such as a Bird Model 43 Wattmeter with theappropriate element (slug) for the frequency range and power output ofthe transceiver.The Bird Model 43 Wattmeter uses elements to set the frequency andpower ranges that the meter will read. The wattmeter element shouldbe a 400 - 1000 MHz model sized so that the forward power readingis close to full scale. For a 5W output handheld, the Bird 5E elementis recommended. If the radio puts out more than 5W, a Bird 10E orhigher power element may be required.Complete the following steps to use a Wattmeter and handheld tocalculate VSWR.1. Connect the wattmeter and transceiver to the feed line in place ofthe R450 RM DC.2. Measure both the forward and reflected power.3. Find the return loss value using Table 13 on page63 and Table 14on page64.4. Find the loss attributed to the coax using Table 15 on the previouspage based on the coax type and feed line length.The adjusted return loss is calculated by the following formula.Return Loss (fromTable) - (2 x Cable Loss) = Corrected ReturnLoss5. Find the VSWR using Table 13 on page63 and Table 14 onpage64 using the Corrected Return Loss value.6. Change the frequency on the handheld transceiver to theR450 RM DC's receive frequency.7. Measure the power and calculate VSWR using the procedure justused for calculating transmitter VSWR.8. Record both transmit and receive frequencies' VSWR values. Inorder for the antenna system to pass, both readings must be lessthan 1.5.1.R450 Rack Mount DC Installation and Maintenance Guide 67Appendix A: RF Antenna Installation
Using the AEA 140-525 Antenna AnalyzerComplete the following steps to configure the analyzer.This procedure assumes that the analyzer has not been configuredprior to use.1. Turn the analyzer ON.2. Type the frequency: 46000.3. Press Enter.4. Set the value next to WID on the screen to 20 using the widthbuttons.5. Set the reading to return loss by pressing F1 three times. (Press itslowly; the unit should beep each time.)Taking the Reading and Calculating VSWR1. Connect the analyzer to the feed line in place of the R450 RMDC.2. Configure the analyzer using the preceding procedure.Be sure that there is not a vertical line running through the displayin the plot area. If there is, press EXAM PLOT and it should goaway.3. Allow the analyzer reading to stabilize, between 10 and 20seconds.4. Press EXAM PLOT to freeze the display.5. Move the cursor (the vertical line in the middle of the screen)using the FREQ arrows to approximately the R450 RM DC'sfrequency. (It moves to within 100KHz of a frequency.)6. Read the value next to RETL on the display. This is the returnloss value.7. Find the loss attributed to the coax (based on the coax type andfeed line length) using Table 15 on page66.8. Calculate the adjusted return loss using the following formula.Return Loss (from Table 5) - (2 x Cable Loss) = CorrectedReturn Loss.9. Find the VSWR (using the Corrected Return Loss value) Table 13on page63 or Table 14 on page6468 R450 Rack Mount DC Installation and Maintenance GuideAppendix A: RF Antenna Installation
10. Move the cursor to within 100KHz of the R450 RM DC's receivefrequency.11. Calculate VSWR using the new return loss value.12. Record both values. They must be less than 1.5.1 for the antennaand feed line to pass the test.General Installation GuidelinesUnpackingAs with all precision electronic instruments, the RF 450 MHz antennashould be handled with care; however, no additional special handlingis required.After unpacking the RF 450 MHz antenna, inspect it for damage. Ifany parts of the R450 MHz antenna appear to be damaged or prove tobe defective upon installation, notify your Neptune salesrepresentative. If the unit or item requires reshipment, use the originalcardboard box and packing material.In particular, check to be sure that the N connector at the base of theantenna is not damaged. This is much easier to check while theantenna is on the ground than after it is installed.RF Antenna Installation KitThe RF 450 MHz antenna and the basic accessories are included withthe R450 RM DC. The mounting brackets that are included aredesigned to mount on the top of a mast or similar structure. If theinstallation requires offsetting the antenna from the supportingstructure, this must be ordered separately. Neptune does not sell it.Figure 42 – RF 450 MHz AntennaR450 Rack Mount DC Installation and Maintenance Guide 69Appendix A: RF Antenna Installation
