Lightning Protection
WARNING: The following notes are general recommendations for the system. The
wireless equipment should be installed by a qualified professional installer and
must follow local and national codes for electrical grounding and safety. Failure
to meet safety requirements and/or use of non-standard practices and procedures
could result in personal injury and damage to equipment. A direct lightning strike
may cause serious damage even if these guidelines are followed.
All outdoor wireless equipment is susceptible to lightning damage from a direct hit
or induced current from a near strike. Lightning protection and grounding practices
in local and national electrical codes serve to minimize equipment damage, service
outages, and serious injury. Reasons for lightning damage are summarized as:
- Poorly grounded tower/antenna sites that can conduct high lightning strike
energy into equipment.
- Lack of properly installed lightning protection equipment that can cause
equipment failures from lightning induced currents.
A lighting protection system provides a means by which the energy may enter
earth without passing through and damaging parts of a structure. A lightning
protection system does not prevent lightning from striking; it provides a means for
controlling it and preventing damage by providing a low resistance path for the
discharge of energy to travel safely to ground. Improperly grounded connections
are also a source of noise that can cause sensitive equipment to malfunction.
A good tower grounding system disperses most of the surge energy from a tower
strike away from the building and equipment. The remaining energy on the IF
cable shield and center conductor can be directed safely to ground by using a
lightning arrestor in series with the IF cable.
To limit the equipment damage due to a lightning strike, the following practices
are recommended for the wireless system:
- Provide direct grounding from the antenna mounting bracket, the radio and
antenna and the lightning arrestors to the same ground point at the base of the
tower or a ground bus on the building. Use the grounding screws on the antenna
bracket and the radio and antenna for terminating the ground wires.
- Install one RF lightning protector between the radio and antenna in series with
the RF cable.
- A lightning arrestor in series with the IF cable at the point of entry to the
building.
- Install a lightning arrestor in series with the IF cable at the transceiver on the
tower/mast.
- The AC wall outlet ground for the terminal must be connected to the same
grounding system as the radio and antenna lightning protectors.
- The ground connection on the back of the terminal should be connected to the
same ground for the building.

pre-selected action, such as disable transmission or relocate transmission to
alternative frequency. The system also includes an automatic transmitter power
control (ATPC) function to automatically adjust the Tx level of remote-end
systems to match a selected RSSI value.
The AN-50e system utilizes Redline’s advanced Medium Access Control (MAC)
design to provide efficient transmission of data in both PTP and PMP modes. In
PMP mode, the MAC incorporates a proprietary polling algorithm to support up to
250 individual subscriber stations from a single master end operating in a single
sector. Note that multiple masters can be installed on a single rooftop or tower to
provide multi-sector coverage.

A single sector AN-50e PMP implements a distributed wireless L2 switch, with
one uplink port located on the sector controller (master) distributing bandwidth to
a variable number of subscriber stations (slaves).
- Each subscriber station (remote-end) is considered a separate wireless link.
- Each configured wireless link adds to the switch one remote-end port that is the
Ethernet port on the corresponding subscriber station.
- Each link (remote-end) is assigned one ID that is used to manage both the
connection traffic and the wireless link.
- The switch supports one broadcast/multicast group called default group, which
is automatically assigned a fixed ID.
The master-end MAC utilizes a request/grant polling mechanism to determine
which subscriber station requires bandwidth. This is achieved by periodically
polling each subscriber station to determine if there is a request for bandwidth. If
the subscriber station requests bandwidth then the MAC allocates the appropriate
number of time slots, in both the downstream and upstream direction, in
accordance with the CIR rate limits specified for that particular subscriber station.
The AN-50e PMP system supports 18 programmable CIR levels. Through an
external calculator the minimum Committed Information rate CIR rates allowed
for each subscriber station can be determined. Note that a minimum CIR of 8 Kbps
implies almost no CIR, and is referred to as Best Effort (BE) service.
With multiple subscriber stations compete for bandwidth, the MAC ensures that
time slots are allocated in a balanced manner, according to the different CIR
levels, during periods of over-subscription. For example, during peak times, the
MAC will first deny time slot allocations for everything above the provisioned
CIR, and then reduce bandwidth in a proportional manner to the remaining units
with varying CIR levels and priorities. With the support of CIR, the service
provider can offer different grades of service to each end user in a controlled
manner based on their service level agreements or contracts.

General Site Survey
Site Path Survey
The RF signal path profile is required to determine the location, height, and aiming
requirements for installation of the wireless system radio/antenna.
Site Path Profile
The completed path profile should include the following information:

Description
Instructions to identify the location for installing the antenna mast.
May include blueprints and specify material list.
Mounting height for antenna.
Horizontal aiming direction for the antenna (magnetic or GPS
compass)
Vertical aiming for antenna (spirit level).
Use the Link Budget tool to determine the expected receive signal
strength (RSSI).
A critical parameter to consider is the range at which communicating wireless
systems are required to operate. Range performance is determined by empirical
formulas that consider a number of equipment and environmental factors.
The Link Budget Tool will calculate expected performance of the link for a
specified range. Ensure that the installation sites will meet performance
requirements before moving to the next step.
Identify Best Path
The next step is to conduct a general site survey to determine the location for the
antenna. This involves a survey to identify building and structures that can be used
to mount an antenna. Refer to the specification for the maximum IF cable length.
For maximum performance in OLOS deployment, it is recommended to mount the
antenna in a location where there is direct line of sight to the receiving wireless
system. If the obstruction in the path is not exceptionally high, it may be possible
to aim both antennas near the top of the obstruction. The antenna should be
positioned to provide maximum clearance within the first Fresnel zone of the
direct path (as high as possible, on either a tall building or tower).
The wireless system also supports installation in non-line-of-sight (NLOS)
conditions. A satisfactory multipath RF signal can often be obtained by directing
each antenna towards a structure in sight of both communicating wireless systems.

Figure 9: Antenna Mounting Locations
The recommended method for obtaining a satisfactory RF signal is to test a
number of antenna positions and measure the signal-to-noise ratio and received
signal strength (RSSI) for each position. Antenna aiming instructions are provided
in section 5.7: Antenna Alignment on page 40.
Channel Selection -- Identify RF Interference
It is also important to test for RF interference at the intended rooftop or tower
installation site. RF interference can be caused by any wireless system in the area
that is operating in the same frequency band as the wireless. Accurate analysis
requires the use of specialized RF test equipment. The primary purpose of these
tests is to determine what channels are available for use on the wireless system.
Antenna Mounting Equipment
When the antenna location has been established, plans should be made for
installation of the antenna mast or alternative mounting equipment.
IF Cable Routing
Plans should be made for routing the IF cable from the radio/antenna to the
terminal. In some locations it may also be possible to install the IF cable on the
outside of the building. If the building must be penetrated to run the IF cable, it is
important to verify that building blueprints and/or drawings are up to date and
accurate, and that all permissions are obtained for the required modifications.

3. Ground the radio and antenna and the mounting bracket using the grounding
screws provided. All grounding connections should be made with wire that is
at least #2 AWG. Painted or dirty surfaces should be cleaned thoroughly down
to bare metal and connections should be well tightened. Follow all local and
national codes.
5.6.5
Weatherproofing Procedure
The professional installer may use their own weatherproofing preferences,
provided they do not use silicon-based materials or PVC tape.
Important: This method of weatherproofing must be completed on ALL external
connections. If lightning arrestors are used, all the associated connections and
arrestors must be completely wrapped in splicing tape.
1. Begin by wrapping with splicing tape. Try to start as close to the radio/antenna
as possible. Stretch and wind the tape back along the connector housing
making very sure there are no gaps in the tape. Continue to wrap the tape
tightly along the cable for at least 15 cm.
2. Use mastic putty and work this in well around the connector and the body of
the radio. Continue to work the putty to make a watertight seal.
1. The connection is now weatherproof.

Antenna Alignment
The antenna alignment can be performed after the antenna and transceiver are
mounted and connected to the terminal using the IF cable.
It is recommended to perform alignment first on one antenna, and then to repeat
the procedure at the remote-end end.
5.7.1
Basic Alignment
Basic antenna alignment can be performed using the alignment voltage pin built
into the transceiver. This transceiver alignment pin is always active. A higher
voltage indicates a stronger signal received from the remote-end transmitter.
The site survey should include the antenna aiming instructions. When using a
magnetic compass, the tower metal will affect the accuracy. Magnetic declination
(difference between true North and Magnetic North) must also be taken onto
account.
Swing the antenna elevation adjustment through the peaks and valleys to obtain
the maximum strength. Repeat this to obtain maximum strength for the azimuth
adjustments. Repeat these steps for the remote-end antenna. When the alignment is
complete, all loosened nuts should be tightened. Tightening all nuts evenly in
rotation may help avoid altering the antenna position.
If the link is non line-of-sight (NLOS), a suitable reflecting surface such as a
building or billboard must be used. The only certain way to determine if a NLOS
link will work is to install the link and then swivel the antennas until a usable
signal is received.
5.7.2
Verify Alignment Using RSSI
Once the basic alignment has been completed, the RSSI value should be checked
against the estimated value obtained from the link budget. If the link is LOS, the
value should not differ by more than about 5 dBm. If the RSSI is much less than
the budget prediction, the antenna may be aligned to an OLOS, or an NLOS path.
It is also possible that the antennas may be aligned to a sidelobe. Alignment on a
sidelobe of the received beam may be indicated by an unstable reading or a large
difference in RSSI values at each end. A thorough elevation and azimuth sweep
should then be repeated, while observing the RSSI values. The value should rise
when a sidelobe is aligned, then fall and rise higher when the antenna is aligned to
a direct signal path. Further movement of the antenna will cause the RSSI value to
decrease and rise to a lower peak as the antenna is aligned to another sidelobe.
This procedure should be repeated for both the elevation and azimuth at each end
of the link.

DFS Action: Select the mode of operation for DFS.
The system set to master-mode monitors for interference from radar devices and
other equipment using the same channel frequency. When interference is detected,
the system automatically takes the action selected using the drop-down menu:
Important: DFS Action selection should be set to None where DFS function is not
required by regulations. DFS cannot be disabled where required by regional
regulations.
None: DFS is disabled.
Tx Off: Transmission is immediately disabled when radar signals are detected.
This action is recorded in the message log and an SNMP trap message is sent
(if SNMP enabled).
Following an interval of thirty minutes, the same channel is monitored for one
minute and if there are no DFS triggering events, the system resumes normal
operation. If DFS trigger conditions are still detected, operation is suspended

events are detected or the operator manually reconfigures the system.
Chg Freq: Relocate transmission to alternative frequency immediately when
radar signals are detected. This action is recorded in the message log and a trap
message is sent (if SNMP enabled).
The new channel is selected based on allowable frequencies for the regulatory
region of that installation. The channel is monitored for one minute before the
system is allowed to transmit. If DFS triggering events are detected, the next
available channel is selected and monitored. The system is not allowed to
return to a channel on which DFS trigger events were detected for a period of
thirty minutes. If DFS trigger events are detected on all channels the system
suspends operation until the thirty-minute time interval expires for at least one
channel.
DFS Antenna Gain: Enter the gain (dBm) for the system antenna.
It is important that this value is set to correctly match the antenna gain. If the
antenna gain is set higher than the actual antenna gain, the DFS is less sensitive to
detecting interference, and the system is not operating in compliance with the
UK/ETSI standard. If the antenna gain is set lower than the actual antenna gain,
the DFS is more sensitive to detecting interference and may cause false triggers.
Important: The DFS Antenna Gain must be set when DFS is required by regional
regulations.

Diagnostics and
Troubleshooting
Troubleshooting can be performed using the front panel LEDs and the host
computer/server connected locally or remotely to the terminal.
Important: Before beginning any troubleshooting via the front panel, check that all
cables are securely attached. Also verify that all fields on the System
Configuration page are correct for both the local and remote-end terminals (entry
errors in these fields may cause the terminal to be unable to establish a
communication link).
This section provides basic diagnostic and troubleshooting procedures to help
solve problems that may occur with the system. If, after reading this section, you
are unable to get the system operating properly, please contact your local Redline
representative. Include the model name and serial number of the system (located
on the back of the terminal) in your communications.

Front Panel Diagnostics
The front panel of the terminal includes a LAN interface and three groups of status
indicators to help with first level diagnoses of problems encountered with the
terminal.
Figure 31: Front Panel LEDs
System Reset Button
Throughout this section, reference is made to the Reset button, which is a microswitch recessed in the front panel in the system block. Use a small narrow object,
such as a paper clip, to access the button.
Depressing the button for less than five (5) seconds will activate a short reset,
which is equivalent to turning the terminal off and on. Statistical values are reset,
and the currently loaded software / firmware will be retained. Note that a short
reset may be accomplished remotely by clicking on the System Reboot button
from System Configuration screen.
Depressing the Reset button for more than five (5) seconds executes a long reset.
A long reset reloads the factory default configuration settings such as IP Address,
IP Subnet Mask, Channel, System Name, Passwords and restarts the system. The
software version that existed in the system before the long reset is retained.
An example of when a long reset will help is in the event that a password or IP
address is forgotten. The long reset function will simply restore the system back to
its original factory default settings. A long reset is confirmed by the Wireless Link
LED flashing three times, followed by the LED power-up sequence:
All Ethernet LEDs light for one second, then individual Ethernet LEDs blink twice
in the following order: FD/Col, 100, and Link/Act. The Fault LED lights for
approximately four seconds, then turns off. The two Wireless LEDs remain off for
approximately five seconds, and then blink once. Following this sequence, all
LEDs will indicate the current operational status.

Troubleshooting the Web Interface
These troubleshooting hints assume that the status LEDs on the front panel of the
terminal indicates normal functionality.

Information)
cannot be
accessed.
Possible
Problem
Incorrect IP
address and/or
Subnet Mask.
Problems with
host computer, or
terminal.
Host PC ARP
table is
incorrectly
configured
Solution
Perform a ping test from the host computer
command line.
If the ping test is unsuccessful, then the problem
is with the IP address. Perform a long reset to
apply the default address (192.168.25.2) and
Subnet Mask (255.255.255.0)
If the ping is successful try a short reset of the
terminal, and/or reboot the host computer.
Run 'arp:d' whenever the terminal is swapped.
Check that the subnet mask for the host PC
matches the subnet mask of the terminal. Check
that the host PC's address is 192.168.25.n,
where 'n' is not equal to 0,2, or 255.
Attempt to login to the terminal using a Web browser. Microsoft Internet Explorer
is recommended. If the terminal does not respond by displaying the login dialog
box, check that the correct IP address is being used. The value 192.168.25.2 is the
factory default value and may have been changed during installation.
The next test is to verify the IP address is reachable from the computer. Use the
ping command to test the connection between the terminal and host computer. The
system will always respond to ping frames less that 577 bytes in length.
>Ping 192.168.25.2
If the ping test is successful, the host computer was able to send and receive
packets to/from the terminal. The problem may be with the Internet browser or
related settings on the host computer. Re-boot the host computer to try to resolve
the problem.
If the ping is unsuccessful, there may be problems using that IP address; the IP
address may be incorrect, or there may be a duplicate address. For correct
operation the host computer and the terminal must appear to be on the same
subnet. For example, if the terminal is using the factory default settings, the host
computer could be set for an IP of 192.168.25.3 and a subnet mask of
255.255.255.0.
If the correct IP address of the terminal cannot be determined, it is recommended
to perform a long reset to restore the terminal to the default value.
Warning: performing a long reset will restore the terminal's IP address
(192.168.25.2) and IP Subnet Mask (255.255.255.0) to the factory default value.

DC Power Supply Cable Connections
This section provides important instructions for connecting to a DC power source.
The DC power supply (optional) is rated for operation using 24, 48 or 60 VDC.
Power is connected to the terminal via a fused power entry module located on the
rear of the terminal. All DC terminals are shipped with a power cord assembly,
consisting of the power entry module’s mating dual pin polarized female plug, precrimped with 18 AWG blue and black insulated wires.
Important: All power wiring must be at least 18 AWG.
The DC power input is floating (+Ve and -Ve not connected to chassis), allowing
positive (minus to ground), negative (positive to ground) and floating power
connections as required. Refer to table below for connection details.
If the terminal does not power-on, it is possible that the blue and black wires are
connected incorrectly resulting in a reversal of polarity. In this event the diode
protection prevents permanent damage to the power supply. Reverse the power
connections and verify that the terminal powers up properly.
