Chapter 5: Troubleshooting
If the R450 RM DC is offline, this indicates that they power, power
supply, CPU, or backhaul modem may not be functioning.
Some sites are configured so that an operator can log on the
R450 RM DC remotely and look at the logs and watch the system
activity. If the R450 RM DC is offline but it is still possible to log
on the system, this indicates that the computer and backhaul
modem are both functional.
Initial Site Activities
Open the R450 RM DC and inspect the equipment.
Make sure that there is no obvious physical damage to the system,
such as evidence of burned components or wires, which may
indicate a lightning strike. If there is any evidence of physical
damage, the R450 RM DC should be replaced with the spare and
returned to Neptune's repair facility.
CAUTION: The ground wrist strap must be clipped to the
box. Do not touch the computer circuit board or any of the
components if you are not wearing the wrist strap. Failure to
use the strap could cause damage to the computer due to
static electricity.
Checking the General Health of Each of the Modules
Visual Check of CPU Board Power
There are three Ethernet Status Light Emitting Diodes (LEDs) to the
left of the Ethernet RJ45 connector. The red LED closest to the
connector should be lit if there is power being supplied to the CPU
board. See Figure 36.

Chapter 5: Troubleshooting
Visual Check of Radio Power
The radio has several indicator LEDs on the front panel. The green
Power indicator should be on. See Figure 37. If the amber ALM LED
is on, the radio is malfunctioning.
Figure 37 – Radio LEDs on Front Panel
Visual Check of Backhaul Modem Power and Connectivity
Cal Amp Vanguard Modem
Look at the indicator lights on the modem to verify if the modem is
working. See Figure 38.
If the RSSI and SVC lights are on, this indicates that the modem is
connected.
If the RSSI and SVC lights are not on, this indicates that there is a
power problem with the modem. Verify that the main power is on.
If the SVC light is solid, the modem is connected to the cellular
network. See Table 9 on the facing page.
If the SVC light is flashing, the modem is trying to connect to the
network. See Table 9 on the facing page.

Additional Detail Checks
If any of the previous checks failed, the following detail checks
should be performed.
Power supply voltage checks should be made one at a time so that a
load remains on the power supply. This is especially true of the CPU
and modem voltage checks. With no load on the power supply,
erroneous values may be measured.
Verify Main Power
Usually, it is a good practice to check the main power and make sure
it is within specification. If there are no power indications on in the
R450 RM DC, this must be checked.
The circuit breaker should be in the ON position. Verify that it has
not tripped.
Using the voltmeter, verify that there is 120V AC on both the AC
feed and the power supply sides of the circuit breaker.
R450 Rack Mount DC Installation and Maintenance Guide
49
Chapter 5: Troubleshooting
If voltage is not present on the AC feed side of the circuit breaker
or is less than 110V, there is something wrong with the supply
voltage. Repairing this is outside of the scope of this manual
The R450 RM DC is capable of functioning on voltages as low as
90V.
If voltage is not present on the power supply side of the circuit
breaker and the circuit breaker is not tripped, the breaker is
damaged. If the circuit breaker is damaged, it is recommended that
the R450 RM DC be returned for repair.
Verifying CPU Board Power
Neptune recommends checking the voltage levels going to the
computer.
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 of
the CPU Board. There is a locking tab on the bottom side of the
connector.
4. Turn the circuit breaker back on.
Figure 39 – Red and Black Leads
50
R450 Rack Mount DC Installation and Maintenance Guide
Chapter 5: Troubleshooting
5. Use the Digital Volt-Ohm-Multimeter to measure the voltage. The
red leads are positive; the black leads are negative.
6. The voltage must be between 4.9V and 5.2V. Turn off the
R450 RM DC circuit breaker.
If the voltage is above or below these values, it indicates that the
power supply is defective. Return the R450 RM DC to Neptune's
repair facility.
7. Reconnect CPU power.
Verifying Radio Power
1. Turn off the circuit breaker if it is not already off.
2. Remove the BATT connector on the radio. The locking ring
unscrews.
3. Turn the circuit breaker back on.
4. On the power cable connector, measure the voltage across pins X
and Y as shown.
5. The voltage should be between 14.5V and 15.5V. If the voltage is
above or below these values, the power supply is defective and the
R450 RM DC should be returned to Neptune's repair facility.
6. If the voltage is within specifications, turn the circuit breaker off
and replace the connector. Make sure that the connector locking
ring is finger tight.
Verifying Cellular Modem Power

Verifying Cellular Modem Connectivity
Cal Amp Vanguard Modem
To verify connectivity and signal levels, complete the following.
1. Locate the RSSI LED light on the modem.
2. Identify how the light is lit.
Solid = indicates signal strength is strong
Blinking = indicates signal strength is medium
Off = indicates signal strength is poor or no signal at all
Figure 41 – CalAmp Vanguard Modem with RSSI LED
3. If the signal strength is poor or if there is no signal at all, there is
something wrong with the antenna, or it is possible that the local
cell 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.

Chapter 5: Troubleshooting
Verifying Radio Functionality Using an MIU
To verify that the system is functioning properly, complete the
following steps.
For this test to be valid, there must be regular time beacon
transmissions sent by the R450 RM DC. This is indicated by the
TX indicator flashing every ten seconds. See Figure 37 on page
48. If the R450 RM DC is not sending out time beacons, this test
will automatically fail.
1. Obtain a magnet and an MIU.
2. Swipe the MIU with a magnet so that it will send out a
configuration packet.
3. Watch for the radio's Busy light to turn on. This should happen
within a minute of swiping the MIU.
If the Busy light turns on, it should be followed by an
immediate flash of the TX indicator. See Figure 41 on page 52.
If the Busy indicator is not immediately followed by a flash of
the TX indicator, then there is an internal problem with the
R450 RM DC that may include its configuration, the radio,
NTG modem, or the computer.
R450 RM DC is Syncing but Not Supplying MIU Data
If the R450 RM DC is online, this indicates that the computer and the
backhaul modem are both working. If no readings are being collected
by the R450 RM DC, this indicates that there is a potential problem
with the radio and modem.
Troubleshooting this problem requires going to the R450 RM DC
site.
Initial Observations
After opening the cabinet, assess the following.
The R450 RM DC sends out a time beacon every 10 seconds. The
transmit light on the radio should flash every 10 seconds. See
Figure 37 on page 48. Only the red transmit light should turn on. If
the amber ALM indicator turns on at the same time, this indicates
that there is a problem between the transmitter and the antenna.
If the transmit indicator does not flash, this indicates that there is a
potential problem with the modem or possibly the computer's serial
port.
R450 Rack Mount DC Installation and Maintenance Guide

Chapter 5: Troubleshooting
Transmitter Transmits but ALM Indicator Flashes
This requires measuring the Voltage Standing Wave Ratio of the
antenna system. If the VSWR is greater than 1.5:1, that indicates that
there is a problem with the feed line or the antenna.
Measuring the VSWR
To measure the VSWR (MFJ-269 SWR Analyzer), complete the
following steps.
1. Make sure the red Power button is off. The red button is extended
outward.
2. Press the UHF button to be sure it is extended outward.
3. Turn the Frequency knob fully counter-clockwise. This knob
points to 114-170/UHF.
4. Connect the 2-inch long attenuator pad to the Antenna
Connector. 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 entire
450 - 470 MHz range.
7. Observe the indicated VSWR. It should read 3.0 ± 0.2
This indicates that the unit is calibrated correctly and the batteries
are good.
If the reading is outside this range, then try replacing the
batteries (eight AA batteries).
If this does not improve the readings, the unit needs to be
recalibrated.
8. Power off the unit.
9. Remove the attenuator pad and connect the antenna from the
bottom 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 the
collector 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 or
1.2.
If a flashing SLP indication appears in the bottom-right corner of
the display, this indicates Sleep mode. Simply turn the unit off and
then on again.
54
R450 Rack Mount DC Installation and Maintenance Guide
Chapter 5: Troubleshooting
13. When finished, power off the unit.
The Radio Never Transmits
The simplest test is to cycle power on the R450 RM DC to see if the
radio starts transmitting.
It can take up to 10 minutes for the R450 RM DC to be fully
functional.
If radio starts transmitting, this indicates that there was a soft failure
in one of the serial ports possibly related to the side effects of a
storm.
If this does not fix the problem, then the R450 RM DC has an
internal 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 Collected
If the R450 RM DC is not collecting as much data as before, but it is
still collecting some MIU data, this usually indicates that there is a
problem with the antenna and feedline system or possibly an internal
problem. To determine the cause of the problem, complete the
following steps.
1. Check all the system voltages as outlined above.
2. Check the VSWR of the system using the technique previously
described.
If the VSWR is high, the feedline and antenna should be checked
out and certified by qualified radio personnel.
3. Check the VSWR again, if the power output is low, by placing the
wattmeter 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 the
duplexer or radio, and it is recommended that you contact Customer
Support

R450 Rack Mount DC Installation and Maintenance Guide
Appendix A: RF Antenna Installation
RF Antenna Overview
There are a number of critical items you must consider when placing and installing the
antenna. The following list contains items that can influence the antenna placement and
installation.
Mounting the Antenna
Consider the following when mounting the antenna.
1. Mount the antenna as high as possible with an unobstructed view of the coverage
area.
The supporting structure, if the antenna is not mounted above it, can cause
specific areas of limited coverage.
Water towers in particular can severely limit coverage where the signal must pass
directly through the tank. When mounting the antenna on a water tower, it is
recommended that they be mounted on top as close to the center as possible.
When mounting the antenna on a traditional three-leg or four-leg tower, the
standoff mount for the antenna must position the antenna at least five feet away
from the tower to minimize coverage area problems.
2. Avoid making the R450 Data Collector's (R450 RM DC) antenna the tallest point
in the surrounding area. This may be unavoidable but it increases the potential of
the antenna being damaged by lightning.
Mounting the Antenna Mast
Consider the following.
CAUTION: The antenna mast and stand must be grounded
to the same grounding electrode used for the building's
electrical system to ensure that all exposed, non-currentcarrying metal parts are the same potential. Refer to NEC
Article 810.
When mounting the antennas and antenna mast, it is important to
maximize the line-of-sight relationship between the RF 450 MHz
Antenna and R450 MIUs for optimum RF communications.
R450 Rack Mount DC Installation and Maintenance Guide
57
Appendix A: RF Antenna Installation
WARNING: Antenna contact with high voltage wires may
result in death. Watch for overhead electric power lines
when erecting the antenna and mast.
WARNING: Do not mount antennas on utility poles, electric
service masts, or other structures carrying electric light or
power wires. Coaxial cables must maintain clearance of at
lease 2 feet (.61 M) from power or light wires of less than
250V, or at least 10 feet (3.048 M) from power wires of more
than 250V, per N.E.C., Article 810, C.E.C. Section 54.
Site Recommendations
The following are recommendations for sites with multiple transmitters, receivers, and
antennas. These sites require extra care when determining a location to install the
antenna.
58
Avoid mounting the R450 RM DC antenna so that it is at the same height as
another antenna on the site, regardless of the frequencies.
For sites that have multiple antennas, if possible, mount the antennas one above the
other, separating each by at least 10 feet vertically. This will minimize the
interference between the systems.
The exception to the previous rule is for cellular antennas. As long as the
R450 RM DC antenna is either above, below, or in the middle of the ring of cell
antennas, the two systems can coexist without interference.
Antenna sites that must share space with multiple transmitting systems may require
additional equipment to protect the systems from interfering with each other. These
sites may also require additional engineering to make them perform well.
R450 Rack Mount DC Installation and Maintenance Guide
Appendix A: RF Antenna Installation
If there are radio systems at the site that are already operating on
the 450 - 470 MHz band, it may be advantageous to combine the
signals into one antenna system using the appropriate equipment.
This often works better than attempting to protect the individual
systems from interfering with each other.
Managed antenna sites may require additional equipment and may
dictate how an installation is to be performed. As long as the
installation meets Neptune's minimum requirements, following the
site's requirements is recommended.
Feed Line and Antenna Recommendations
CAUTION: Neptune recommends that you consult with a
qualified installer on the design and installation of the
antenna systems. If the installer is already familiar with the
sites and the existing equipment, this can make the
installation go more smoothly.
Feed Line
The feed line is a significant contributor to both good and poor system
performance. A properly installed feed line is critical to optimal
system performance. Testing the antenna while it is on the ground can
ensure the system is working properly.
Installation of the connectors is best done with the proper tools and a
trained installer. With the proper tools and jigs, installing coaxial
(coax) connectors takes only a few minutes each. Not using the proper
tools as recommended by the manufacturer could potentially cause
problems, either immediately or after several years of apparently proper
operation.
Feed Line Requirements
Consider the following.
The antenna and feed line system installation must be certified by
the installer after it is completed to perform according to
specifications.
Maximum loss for the feed line and connectors must be less
than 3 dB.
The feed line must be bonded at the top of the tower and at the
base of the tower. Andrew grounding kits and procedures should be
used for all bonds.
R450 Rack Mount DC Installation and Maintenance Guide
59
Appendix A: RF Antenna Installation
For towers over 150 feet tall, the feed line should be bonded at
regular intervals down the tower. The general recommendation is
that the feed line be bounded by a minimum of 200 feet. Site
requirements and standard practices should dictate the
configuration.
An optional surge protector may be installed on the tower near the
antenna to help protect the feed line but is not required.
For the AVA5-50 cable or larger, jumpers should be used to go
between the larger cable and the R450 RM DC and antenna
connectors.
Andrew provides installation instructions for Heliax Coaxial Cable.
See Bulletin 17800B Revision C. Neptune can supply a PDF copy
by request through Customer Support.
Cable Guidelines
Prepare the cable for installation and check for damage. You will need
the following materials to install the cable.

The antenna, if mounted on the side of a tower or other supporting
structure, must be mounted so that it is at least five feet away from
the structure. The components to offset the antenna are specific to
the installation and are not included by Neptune with the
R450 RM DC package.
The antenna is large and care must be taken when hoisting it up a
tower so that it is not damaged.
The feed line should not be attached to the antenna while it is
being hoisted up the tower or other supporting structure. The feed
line should be attached after the antenna is in place.
There have been reports of damage to the antenna's N connector
where the center pin has become bent and shorts out the antenna
system. Care must be taken not to damage the connector.

System Certification
The Andrews antenna supplied with the R450 RM DC is specified as
having 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 losses
in the feed line. For instructions, see “Measuring the VSWR” on page
68. The easiest approach is to use return loss instead of VSWR. The
1.5:1 VSWR translates into a return loss of 13.98dB. Refer to Table 13
below, Table 14 on the next page and Table 16 on page 70 to assist
with 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 one
end of the cable and verifying that, after correcting for the cable
losses, the correct amount of power is coming out the other end.

VSWR Calculation
Neptune recommends the following method of computing VSWR.
Taking the reading at the R450 RM DC end of the feed line without
compensating for cabling losses may give a false impression of the
antenna and feed line performance.
Using a Wattmeter and a Handheld 450MHz Radio
The recommended procedure is to use a handheld commercial grade
transceiver that is tuned to the R450 RM DC's transmitter frequency
and an inline wattmeter, such as a Bird Model 43 Wattmeter with the
appropriate element (slug) for the frequency range and power output of
the transceiver.
The Bird Model 43 Wattmeter uses elements to set the frequency and
power ranges that the meter will read. The wattmeter element should
be a 400 - 1000 MHz model sized so that the forward power reading
is close to full scale. For a 5W output handheld, the Bird 5E element
is recommended. If the radio puts out more than 5W, a Bird 10E or
higher power element may be required.
Complete the following steps to use a Wattmeter and handheld to
calculate VSWR.
1. Connect the wattmeter and transceiver to the feed line in place of
the 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 14
on page 64.
4. Find the loss attributed to the coax using Table 15 on the previous
page 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 Return
Loss
5. Find the VSWR using Table 13 on page 63 and Table 14 on
page 64 using the Corrected Return Loss value.
6. Change the frequency on the handheld transceiver to the
R450 RM DC's receive frequency.
7. Measure the power and calculate VSWR using the procedure just
used for calculating transmitter VSWR.
8. Record both transmit and receive frequencies' VSWR values. In
order for the antenna system to pass, both readings must be less
than 1.5.1.
R450 Rack Mount DC Installation and Maintenance Guide
67
Appendix A: RF Antenna Installation
Using the AEA 140-525 Antenna Analyzer
Complete the following steps to configure the analyzer.
This procedure assumes that the analyzer has not been configured
prior 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 width
buttons.
5. Set the reading to return loss by pressing F1 three times. (Press it
slowly; the unit should beep each time.)
Taking the Reading and Calculating VSWR
1. Connect the analyzer to the feed line in place of the R450 RM
DC.
2. Configure the analyzer using the preceding procedure.
Be sure that there is not a vertical line running through the display
in the plot area. If there is, press EXAM PLOT and it should go
away.
3. Allow the analyzer reading to stabilize, between 10 and 20
seconds.
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's
frequency. (It moves to within 100KHz of a frequency.)
6. Read the value next to RETL on the display. This is the return
loss value.
7. Find the loss attributed to the coax (based on the coax type and
feed 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) = Corrected
Return Loss.
9. Find the VSWR (using the Corrected Return Loss value) Table 13
on page 63 or Table 14 on page 64
68
R450 Rack Mount DC Installation and Maintenance Guide
Appendix A: RF Antenna Installation
10. Move the cursor to within 100KHz of the R450 RM DC's receive
frequency.
11. Calculate VSWR using the new return loss value.
12. Record both values. They must be less than 1.5.1 for the antenna
and feed line to pass the test.
General Installation Guidelines
Unpacking
As with all precision electronic instruments, the RF 450 MHz antenna
should be handled with care; however, no additional special handling
is required.
After unpacking the RF 450 MHz antenna, inspect it for damage. If
any parts of the R450 MHz antenna appear to be damaged or prove to
be defective upon installation, notify your Neptune sales
representative. If the unit or item requires reshipment, use the original
cardboard box and packing material.
In particular, check to be sure that the N connector at the base of the
antenna is not damaged. This is much easier to check while the
antenna is on the ground than after it is installed.
RF Antenna Installation Kit
The RF 450 MHz antenna and the basic accessories are included with
the R450 RM DC. The mounting brackets that are included are
designed to mount on the top of a mast or similar structure. If the
installation requires offsetting the antenna from the supporting
structure, this must be ordered separately. Neptune does not sell it.

Appendix C: Ethernet Termination
Straight-Through Ethernet Cable
For most installations, the Straight-Through Ethernet Cable is used. Terminate the
Ethernet cable according to the diagram below using the T-568B wiring standard for
both ends. One end should already be pre-terminated to the switch or hub.
Figure 53 – Straight-Through Ethernet Cable
RJ-45 Crossover Ethernet Cable
On some occasions, a Crossover Ethernet Cable is required. If you require a cable to
connect two Ethernet devices directly together without a hub or when you connect two
hubs together, you will need to use a crossover cable instead.

Appendix C: Ethernet Termination
Determining if You Need a Crossover Cable
One method of determining if you need a crossover cable is to plug
the Ethernet cable from the hub or modem into your laptop computer's
Ethernet port. If the laptop computer can communicate through the
Ethernet port, then the site probably requires a Crossover Ethernet
Cable to be compatible with the R450 Data Collector (R450 RM DC).
