RAy3 microwave units work as a point-to-point link in a full duplex setting with transfer speeds of up
to 1002 Mbps.
Supported are 2 license-free bands 17 GHz (17.10 – 17.30 GHz) and 24 GHz (24.00 – 24.25 GHz).
Bandwidth can be configured from 3.5 up to 112 MHz, independently for Tx and Rx. Modulation can
be fixed or adaptive and can be adjusted from QPSK to 4096QAM. QPSK modulation could be on the
fly (without data loss) strengthened for higher receiver sensitivity by extremely robust FEC – such
modulation is marked as QPSK-S (S means “strong”). RAy3 microwave links operating in 17 and 24
GHz bands can also be operated as a Short Range Device (SRD).
This link is formed by two RAy units, each equipped
by its own parabolic antenna and accessories to be
fully operational.
Link transparency notes
RAy links are transparent for IP and UDP Ethernet
traffic (practically all protocols passes through including
MPLS and many others) except following packets:
• Management packets targeted for RAy units itself
• Special packets for protocols explicitly mentioned in
this manual which are somehow processed by RAy
units (like PTP)
• Packets which did not went through and were discarded due to capacity limitation and/or policy rules (e.g. Shaping ...).
Fig. 1.1: RAy3 – Microwave link
Hardware concept
RAy product line has been designed to have minimum possible number of hardware variants. Upgrade
of functionality does not result in on-site hardware changes– everything is done by activating software
feature keys (see Section 1.7, “Ordering codes” and Chapter 5, Configuration).
HW models are determined only by frequency bands, because both RAy units have identical hardware.
Transmitting and receiving channels are freely defined by software and technically separated from
each other by cross polarization.
Note
Even all units are hardware identical, default factory settings for each RAy in the pair use
different channels for L and U unit, so the link could be established using default radio
parameters.
Cross polarization means that one side of the link uses one polarization for transmission (e.g. horizontal)
and the opposite polarization for receiving (e.g. vertical). The other side of the link is turned by 90°. It
therefore transmits and receives using opposite polarization with respect to the other unit. The practical
result for users is that RAy units for 17 and 24 GHz must be mounted with reverse polarity on both
ends of the link.
RAy3 link requires the use of external parabolic antenna for
each RAy unit – both for physical mounting as well as for the
wireless transmission itself. Parabolic antennas from different
producers are available.
Radio connection between the antenna and RAy unit is ensured
by the waveguide on RAy unit (located across the holder), where
well lubricated antenna waveguide pivot nicely fits in.
1.2.2. Unit mounting
The RAy unit is mechanically fixed to the antenna by 4x M8 screws (one per each side of Ray unit).
Installation and basic adjustment of the antenna is described in the Section 4.2, “Antenna mounting”.
Attaching RAy unit to it by 4x M8x30 (Allen) screws delivered with each antenna or each mount kit is
described in the Section 4.3, “RAy unit mounting”. For adjusting the exact antenna direction see Sec-tion 4.7.2, “Directing antennas” .
Grounding screw is used for a proper grounding of the RAy unit, which
is necessary for its function (ensured by galvanic connection to the
grounded mast through a grounding cable).
One M8 screw (with standard 6-edge head) is delivered with each RAy
unit. Grounding screw has two possible positions (two holes) to be
mounted in. Those are located near the left and right fixing screws of the
RAy unit and both are marked by a yellow grounding symboland both
are equivalent (second hole remains unused). For more information
about unit grounding see Section 4.3.3, “RAy unit grounding”.
Note
Grounding screw function is to ensure proper grounding of the RAy unit (by a grounding
cable), not for mechanical fixing of the unit.
Each unit is equipped with basic mechanical interfaces (antenna waveguide, mounting screws and
grounding screw) and several interfaces for data, power and service purposes located in 3 slots:
Fig. 1.5: Slots ETH1+POE, ETH2Fig. 1.6: Slot S
ETH1+POE
ETH2

Gigabit metallic Ethernet port
This port is capable of powering the unit with any Power over Ethernet (PoE) power
source working according to IEEE 802.3at standard.
Passive PoE from 20 to 60 V is supported (if DC input is required, it could be injected through this connector - the voltage range is identical: from 20 to 60 V).
Slot for user exchangeable SFP module
A wide range of fibre optics Ethernet modules is available. Both single or dual
mode transceivers can be used. An SFP module with metallic RJ45 interface can
also be used.
The SFP LED
Located on SFP, just next to connectors. It is controlled by SFP module. Its function
is specific for each SFP module. The typical behavior is an indication the received
signal from the optical or metallic link to be within operational range.

A set of all necessary bushing parts are delivered with each RAy unit - see a description of
this standard basic accessory SET-RAY3-CON. Additional bushing options for installation
of longer connectors or other equipment are available as well. For bushings installation see
Section 4.4, “Connectors assembly and disassembly”.
All accessories offered by RACOM for proper installation of the complete RAy link setup
(including proper grounding) are tested for compatibility with RAy unit. See accessories listed
in overview and described in details.
Important
All bushings and plugs (including the original plugs in the flanges) must be fitted with Orings and carefully tightened. Otherwise, the unit is not protected against moisture intake
through connectors and can not offer guaranteed functionality.
1.3.1. RJ45 ( ETH1+POE )
RJ45 socket connector marked „ETH1+POE“ is a standard
10/100/1000Mbps metallic Ethernet port. One plastic RJ45
plug for CAT5e and CAT6 cables is delivered with each
RAy unit, ready to be punched to an Ethernet cable.
NOTE: Higher quality and CAT7 compatible RJ45 plugs
are available from RACOM as well – see for example item
CON-RJ45-TLG-CAT6.
This port can be optionally used for power sourcing the
unit by PoE (Power over Ethernet). Both an active PoE
power supply (compliant with at least IEEE 802.3at standard known also as „PoE plus“) and a passive PoE power
supply (with voltage range 20-60 V) are supported.
Technical parameters of PoE power input:
Supported voltage range is 20 to 60 V, distances up to 100 m. Internal RJ45 pins wiring is :
• (V+) ... 1,2,4,5
• (V-) ... 3,6,7,8
It is possible to use all 8 pins or only 4 pins. Use:
• either 4,5 (V+) and 7,8 (V-)
• or1,2 (V+) and 3,6 (V-)
• or both simultaneously
All contacts of RJ45 connector are galvanically separated from RAy unit. It ensures galvanical separation
for any kind of PoE power supply as well as for DC power sourcing (made through DC-RJ45 adapter).
More information about usage and installation of available power options can be found in Section 4.6,“Power supply” and Section 4.5, “Grounding and overvoltage protection”.
„ETH2“ is a standard SFP slot for 10/100/1000 Mbps Ethernet SFP modules, user exchangeable. Both fibre optic
and metallic Ethernet SFP modules are supported. For
optical both single and dual mode fibre optics Ethernet
modules (= 2 or 1 fibers) can be used. CSFP modules are
not supported. RACOM offers all mentioned types of SFP
modules, tested to be RAy compatible as a standard ac-cessory.
The SFP status LED is located just next to the slot. It is
controlled by SFP module. Its function is specific for each
SFP module. The typical behavior is an indication the received signal from the fibre optic or metallic link to be
within operational range.
Do not remove the smaller plastic screw next to ETH2 label.
It is part of the cabinet and assures pressure equalization outside and inside.
Fig. 1.8: SFP slot
Product
Important
It is strongly recommended to use a high quality SFP module with industry temperature
range. The SFP modules listed in Accessories are thoroughly tested by RACOM and are
guaranteed to function with RAy units. It is possible to use any other SFP module, but RACOM cannot guarantee they will be completely compatible with RAy units.
1.3.3. DC power ( ETH1+POE )
Direct DC power source can be used to power the RAy3
unit. Slot „ETH1+POE“ allows to use the DC-RJ45 adapter
as a DC connector. It is equipped by 2 terminals (each 1.5
mm2/ AWG 14) with screws to ensure a perfect connection
with cooper DC power cable. Its other end is then fitted
into RJ45 connector slot „ETH1+POE“ in the RAy unit.
Supported voltage range is 20 to 60 V, both polarities are
supported. Power input is galvanic separated inside RAy
unit. Optional grounding of DC cable should be connected
directly to the mast or to the Grounding screw on RAy
chassis, to ensure proper grounding of the cable. For
grounding to the mast use suitable grounding kit – for example see Grounding kits in section Accessories.
More information about DC power sourcing possibilities
and installation can be found in Section 4.6, “Power supply”.
DC-RJ45 adapter occupies ETH1+POE port. When used, Ethernet connection to the unit
has to be made through ETH2 port. Possible solutions are:
• If fiber optic Ethernet is used (using the correct type of SFP module), RAy3 unit is powered
by DC through the DC-RJ45 adapter.
• If a metallic Ethernet has to be used together with DC power source, then metallic SFP
module in ETH2 SFP slot is one of valid solutions.
Other valid possibility how to power the unit using DC power source is to use passive PoE
injector or active PoE power supply with DC input and deliver the power to Ray3 unit through
Ethernet cable with RJ45 connector plugged in to ETH1+POE slot.
Slot „S“ is shortcut of "Service". It contains system connectors
– standard USB port and a pair of contacts for RSS voltage
output (red + gray ones). Also HW button and Status LED are
located there.
USB-A port is designed for access to RAy management through
USB/WiFi adapter or USB/Eth adapter plugged in to. More information about installation and configuration of available adapters can be found in Quick Guide and in Section 5.4.3, “Ser-vice access” (part “USB Accessories”).
Note
Only RACOM recommended adapters are supported. See section Access adapters.

1.4.2. Service WiFi ( USB „S“)
RAy3 unit can be equipped with the service WiFi interface as
an option. It can be used solely for unit management (no user
data can be transmitted using this WiFi connection).
Optional OTH-W2-WIFI WiFi module (ordering code OTH-W2-WIFI) can be inserted in to the slot “S” USB connector (see
chapter Section 1.4.1, “USB connector ( S )” for more details).
Management of the WiFi port is described in Section 5.4.3,“Service access” (part “USB Accessories”).
1.4.3. Service Ethernet ( USB „S“)
RAy3 unit can be equipped with the service Ethernet interface
as an option. It can be used solely for unit management (no
user data can be transmitted using this Ethernet connection).
Optional Eth adapter (ordering code SET-XA-ETH/USB) can
be inserted in to the slot "S" USB connector (see chapter Sec-tion 1.4.1, “USB connector ( S )” for more details). Management
of this Ethernet port is described in Section 5.4.3, “Service ac-cess” (part “USB Accessories”).
RSS voltage output connectors are located in slot „S“ aside
USB connector. This pair of contacts (red + green ones) allows to connect a voltmeter (pin diameter 2 mm) to the RAy
unit and measure RSS value transformed to the voltage output.
RSS (Received Signal Strength) is a basic parameter used
for directing antennas to the optimal direction. RSS output
voltage is calibrated to be proportional to actual RSS dBm
(for example 0.547 V means RSS –54.7 dBm). Thus a
standard digital voltmeter allows to see RSS value in a digital
form interactively during the antenna alignment. More information about RSS voltage output usage is in Section 4.7.2,“Directing antennas” (part “Voltmeter”) together with several
alternative ways to get this value by other methods.
Fig. 1.15: RSS voltage contacts
1.4.5. HW button ( S )
It is located in a small hole next to USB connector. It can be
pushed by any tiny blunt thing with the diameter up to 2 mm.
Its length has to reach about 7 mm in to the hole. (It can be
ball pen cartridge – both ends work on the thin one, match,
toothpick, etc.).
Important
Usage of very sharp things for pushing the HW
button (like needle, edge clip etc.) may destroy
the contact inside RAy unit! Such a button destruction is not covered by warranty.
The button supports multiple functions, which are activated
dependent on the state of the unit when the button is pushed
and the length of the push:

RAy3 microwave link consists from a pair of units for the chosen band (selected according to Ordering
codes for HW units) with the proper SW feature keys for capacity and SW feature keys for other functions.
Each feature key is generated for the unique serial number of the unit (and does not work in other unit).
Once installed, feature key unlocks a specific feature or function of the unit. Feature keys could be
erased or upgraded.
Ordering codes for accessories, necessary to be added to RAy units to ensure a proper functionality
of the whole microwave link, are listed in Chapter 2, Accessories.
1.7.1. Ordering codes for HW units
The proper pair (from the same row) of Lower and Upper units should be selected when ordering the
microwave link. Both RAy3-17 and RAy3-24 have only one HW model. The difference between L and
U code is only in default factory settings, which are different for each side of the link. Unit marked with
L is set for transmission on lower frequency (and receive on higher one), while unit marked with U is
set for transmission on higher frequency (and receive on lower one). This allows the link to be established
without any initial manual settings – just by powering up both units at factory defaults.

1.7.2. Ordering codes for Capacity feature keys
Maximum user data capacity can be limited by a SW feature key. Capacity feature key defines the
maximum speed of the link. Available speed limits for RAy3 unit are 360 Mbps, 500 Mbps and 1000
Mbps.
Table below shows what combinations of channels + modulations each feature key allows (marked by
colors according the capacity limit in the most right column and in the last row).
Feature keys for capacity could be installed in the factory or purchased separately (and installed by
user). Every Capacity feature key could be upgraded. The capacity limitation for the unit is applied
according the highest speed feature key installed.

Note
If no Capacity feature key is ordered, the unit is shipped with RAy3-xx-x-360 key.
RAy3 functionality with the upgrade feature key (example:RAy3-SW-360-1000) is identical
with functionality of the full capacity feature key with identical final capacity (example RAy3SW-1000). The difference is just in purchase price.
RACOM offers a complete set of accessories to operate RAy microwave units in all relevant use-cases
and environments and provide surge protection. All accessories are thoroughly tested by RACOM for
compatibility and are guaranteed to function with RAy units. It is possible to use other components with
same or similar functionality, but RACOM cannot guarantee they will be completely compatible with
RAy units.
Important
We strongly recommend to double check local power voltage level and local standards for
all necessary accessories to be compliant with local voltage and with all regulations related
to safety and surge protection.
We especially recommend to consult local experts and study local standards regarding
grounding and surge protection to ensure the chosen and installed grounding and protection
meets actual site conditions and safety regulations.
Warranty does not apply for units destroyed by surges (see RACOM warranty conditions
at Section 10.6, “Warranty”).

use of non-RACOM approved WiFi adapters.
The following chapters will guide you step by step through preparation, installation and activation of
the RAy3 link:
• Pre-installation check out
•
Installation (Chapter 4.)
•
Advanced configuration (Chapter 5.)
•
Troubleshooting (Chapter 8.)
Pre-installation Checklist
Default settings for L and U units are chosen to allow delivered units to automatically establish a link
without unpacking RAy3 units from the box. It is enough to open the boxes and power both RAy units
up (by PoE or DC power supplies). It allows users to comfortably set up basic parameters necessary
for the installation in the lab and thus shorten the time on the tower or roof to a minimum. Following
text provides a guide how to optimally arrange the workplace, how to setup the link and which parameters
are good to be set up before the installation outside.
Default factory settings define the initial link to be established on the most narrow channel, strongest
modulation and lowest available Tx power (in RAy3 case those are 3.5 MHz channel, QPSK_S modulation and Tx power = -30 dBm). Complete default settings are described in section 10 Technical
parameters.
Note
RAy3 default factory settings allow to install both units on the mast and establish the short
link without prior manual configuration. Just the distance has to be very short due to Tx
power set to the minimum for the unit (-30 dBm on Ray3-17 and Ray3-24). Typically, Tx
power has to be increased to a reasonable level (or even to a maximum) before link alignment.
Fig. 3.1: Workplace for link testing and configuration
Take the following steps to link together both delivered RAy3 units and to establish a connection
between them and PC or tablet or mobile and perform a basic setup:
■ Open both boxes and double check that both RAy3 units are turned OK, so waveguides are heading
to each other.
■ Connect power sources (PoE or DC) to both RAy3 units (using slot ETH1+POE).
■ Wait about 30 seconds until both units boot up and the link is established. The green light should be
visible on both units through transparent plug on slot “S”.
■ Connect by WiFi or by Ethernet cable (plugged in to LAN input on PoE power supply or in to Eth port
on USB-Eth adapter) to one of those two units. Units linked together allow effectively set all IP addresses, passwords, security keys, feature keys, users, etc. from one side of the link.
○ If WiFi is used, then just select which WiFi to connect to. IP address of your PC or laptop is set
automatically by DHCP.
○ If Eth over USB port is used (through Eth /USB adapter SET-XA-ETH/USB), IP address of your
PC or laptop is set automatically by DHCP as well.
○ If Eth connection to one of data ports on RAy3 (ETH1 or ETH2) is used, then the IP address on
your PC or laptop has to be set manually to establish a working connection. See Quick Guide for
the complete list of IP addresses to use.
○ Enter a web management of the unit and configure everything you like to change to be ready for
outside installation. Following parameters are typically set in this phase:
• IP addresses and VLANs
• passwords
• security keys
• feature keys
• users
• WiFi behavior
• Tx and Rx frequencies (if known in advance)
• Higher Tx power (to be ready for antenna alignment) – see section “Important” below
Note
This setup can be used for link configuration, however full radio performance can't be
•
expected (high modulations, full Tx power range, etc.) because standard conditions
between units (antenna interface, polarization planes, free space attenuation) inside the
box are not met.
• High TX power does not lead to better RX signal quality, because the receiver input can
be saturated with too strong signal (see more info in chapter 8. Troubleshooting, topic
Overexcited receiver).
Important
Maximum secure Tx power for RAy units inside the box is 0 dBm. Higher Tx power risks
•
the damage of sensitive input circuits!
• If you need to configure higher Tx power to be ready for antenna alignment during installation on the mast, you first have to turn units in to position where waveguides are not
heading to each other, so reasonable attenuation is ensured. Secure is for example to
put RAy units in parallel in to a direction without any metal material in front of the microwave
beams (it could reflect waves back to units).
• Maximum time units can be powered up inside the box is 10 minutes (standard room
temperature expected). Longer time may lead to the unit overheat! If more time is needed
for configuration, units have to be unpacked from boxes.
The RAy3 link is supplied with a default configuration of access parameters:
For Ethernet access through RJ45 or SFP ports:
• Unit L has the service IP address 192.168.169.169 and mask 255.255.255.0
• Unit U has the service IP address 192.168.169.170 and mask 255.255.255.0
For WiFi or Ethernet access via USB/WiFi or USB/Eth adapter:
• Both units have service IP address 172.17.17.17 and mask 255.255.255.0
For Ethernet access through RJ45 or SFP ports an IP address has to be set on your PC that is within
the mask, e.g. 192.168.169.180. For WiFi or USB/Eth access an IP address for laptop or mobile or
tablet is set automatically by DHCP (enabled by default).
Then open the http or https configuration interface, e.g. https://192.168.169.169 or http://172.17.17.17
Access is allowed over HTTP, HTTPS or SSH.
The default username is "admin" and the password is also "admin" (it is strongly recommended to
change it).
See Configuration / Link settings / Service access / USB accessories chapter for detailed information.
The Antenna Alignment Web Tool can also be used for antenna direction alignment. It can be accessed
via a web browser utilizing IP addresses with „/tk“ at the end (e.g. http://172.17.17.17/tk for WiFi or
USB/Eth adapter or http://192.168.169.169/tk or http://192.168.169.168/tk for ETH1/ETH2 ports).
When connection has been established, use the Service access menu to customize access parameters.
Default management IP addresses should be replaced with well-chosen operating addresses. Default
can lead to network problems later.
The menu contains parameters for the entire link, both for the Local and remote Peer units. If a connection has been established, both sets of parameters have been set. While working with an isolated unit,
only Local parameters are functional for the currently connected unit.
Note
If the link is OK and there are no parameters shown of the station Peer, it is necessary to
click on Refresh.
Follows the description of basic settings. Pictures in following sections show default factory settings
for L unit and RC info “rcinfo20_250_default:XXX”. Default settings for unit U (for opposite side of the
link) would be adequately exchanged. Values for other RCinfo may be different as well (differences
typically refers to frequencies and Tx power as they are allowed by authorities for the actual band and
a region).
After entering values on the screen always save the content by clicking on Apply.
Note
If there is any problem with https certificate after completing the firmware upgrade, please
see the Annex Https certificate for further steps.
3.1.1. Choosing right band according the country of use
Menu Tools / Maintenance / Radio adaptation
First step is to set the right set of rules for the band according the region or country of use, so the unit
is compliant with the local regulation. Go to the menu according the picture below and set parameter
RCINFO accordingly.
Fig. 3.2: Menu Tools / Radio adaptation
For full explanation of all possibilities of this screen see the section called “Radio adaptation”.
Those settings are necessary to make new units accessible within target Ethernet network. Typically,
all following parameters should be set according to both networks IP addressing, routing, planned access
methods for data and for management, etc.:
• IPv4 address – enter a valid IP address to access the unit. The default IP address has to be replaced
with a valid address. Keeping the default address will probably lead to future problems in the network.
• Netmask – enter the network mask.
• Gateway – if necessary, enter a gateway, otherwise leave blank
• Enable access protocols that you are going to need. For security reasons, do not enable more than
is necessary.
• HTTP(S) – allow access to the web interface.
• Telnet – enabling access to the CLI interface using telnet protocol.
• SSH – enabling access to the CLI interface using SSH protocol.
• Management VLAN – Enabling 802.1Q VLAN tag for separation of user and service operations.
• Management VLAN id – Defining 802.1Q VLAN tag for service operations.
Fig. 3.4: Configuration menu Link settings / Service access / Services
For full explanation of all possibilities of this screen see the section called “Services”.
It is recommended to create user accounts managed by the main user already in this phase (for example
a user with rights limited to read-only access). Following actions are available:
• Edit - enter the menu.
• New password – choose a password and enter it.
• Confirm password – enter the password again to confirm.
Fig. 3.5: Configuration menu Link settings / Service access / Users
For full explanation of all possibilities of this screen see the section called “Users”.
The firmware of the microwave link is capable of controlling several features (for example the maximum
user data speed, maximum Tx power, etc.). It is recommended to install all separately purchased feature
keys prior to physical installation to allow all expected features of the link to be usable after the installation.
Fig. 3.6: Configuration menu Maintenance / Feature keys
Note
Speed keys purchased with the unit are installed in the factory (and can be double checked
within this menu). Key for limited Tx power is not installed except specifically ordered. If
RCinfo limits the maximum power, it can not be overruled by feature key with the higher Tx
power.
For full explanation of possibilities of this screen see the section called “Feature keys”.
Go to menu Link Settings / Service Access / USB accessoriesand enter WiFi password or disable
WiFi completely. Standard settings are that Enable on Air link loss is ON (when the link is down, WiFi
is activated; when link is OK, WiFi will be deactivated in few minutes) and Force Enable is OFF (activates
WiFi permanently). Passphrase has to be set, otherwise the WiFi is unsecured and system warning is
active.
Fig. 3.7: Configuration menu Link settings / Service access / USB accessories
Note
If you access the unit over WiFi, do this step as last action before reboot (as the WiFi connection will be interrupted and new connection with new password would be required to
continue the work).
For full explanation of possibilities of this screen see the section called “USB accessories”.
Default radio parameters depend on the specific type of link and the specific channel allocation table.
Channels are typically set in the lower part of the band, the smallest bandwidth, QPSK modulation,
and low power. Both units in the pair should be capable of immediate communication. If it is possible to
work with these radio parameters at the installation location, the link can be activated. On an operating
link the required operating parameters can then be set up.
If a change in the parameters is necessary, it is done in the menu Link settings / Radio and saved by
clicking Apply. This applies when working on both units simultaneously if they are connected, otherwise
each unit is configured individually. When configuring units individually, pay attention to correct settings
of duplex pair for channels TX and RX. For example, if one station has TX channel L1, then the second
station must also have the channel RX L1.
3.3. Link test
Verify the functionality of the radio link:
•
Switch in screen Status / Brief.
•
Status Bar displays Link: Ok.
If the alarm message appears at Local or Peer, this doesn’t necessarily mean there is a problem.
The message indicates that the limit at any of the monitored parameters has been exceeded. Essential
is the "Link: Ok" message on the status bar.
•
The Status screen contains values for both Local and Peer units. N/A next to Peer indicates that the
data from the Peer unit has not been transferred. If Link is Ok, simply click Refresh at the bottom of
the screen and Peer data will be updated.
•
Menu Status / Detailed / Radio indicates link RSS and SNR values, in case of ACM also the selected
modulation and Netbitrate. If the ATPC function is enabled (menu Link settings / Radio) it also indicates instantaneous / max. allowed power and for SNR and RSS values it indicates immediate / target
value size.
•
Menu Tools / Live data / Bar indicators displays current size of RSS, SNR and BER.
•
Menu Tools / Programs / Ping allows you to send a ping test to the selected IP address.
Try out the possibility of modulation:
•
Modulation ACM. In menu Link settings / Radio enable ACM. Set the TX modulation parameter to
the required maximum value. In menu Status / Brief / Radio you can monitor (Refresh or Start)
changes in used modulation based on the instantaneous SNR signal quality.
•
To set a fixed modulation go to Link settings - Radio, switch off ACM and set the TX modulation to
a value from the range of QPSK through 256-QAM based on the results of the previous test. If you
choose modulation higher than allowed by SNR, the connection will be lost. Status Link will lose its
Ok value. Both units will need to be moved closer to resume the link. If this is not possible, use the
ethernet to access each unit individually and set the basic modulation QPSK.
Verify the functionality of the entire link:
• If possible, connect user devices to both RAy units over PoE and test mutual communication.
• Another way of testing this is to connect a PC to the other unit and send a ping from one PC to the
other.
• The minimum variant of this test is to use an ethernet cable connection from the PC connected to
the local RAy to the PC connected to the remote RAy and test communication between both units
over ethernet. This will verify ethernet functionality.
• Bandwidth e.g. 3.5 MHz. To get the highest possible receiver sensitivity, set the bandwidth as narrow
as possible according to specific frequency band.
• TX channel: Use your allocated channel. If you do not have allocated channel yet, use for example
channel L1.
• RX channel will setup automatically when channel lock activates.
• Set TX modulation QPSK to get the highest possible sensitivity.
• Set RF power according to selected antenna and according to individual frequency licence. Set the
output power as high as possible.
•
Set a new users access passwords.
• Record the access parameters from the Service access menu, especially the IP addresses.
• Restart by interrupting the power supply to verify that the parameters are stored correctly and the
link works.
After this preparation phase you can continue to install your devices in a working environment.
Before you install the device to a mast tube, verify visually that the view in the direction of the remote
unit is unobstructed.
Line of sight considerations:
• Free Fresnel zones. Signal needs space wider than the diameter of the antenna.
• Trees at the lower end of the Fresnel zone. They will be taller in a few years.
• Possible building development.
• Objects in the close proximity of the antenna such as edges of other antennas, their mounting racks,
edges of the roof.
Fig. 4.1: Fresnel zone
4.2. Antenna mounting
Antenna mounting depends on the antenna vendor, antenna type and the size of the chosen antenna.
The result of any antenna installation is that it is fixed to the mast, pointing to the right direction and its
waveguide and fixing screws are ready for mounting RAy unit to it.
Common for all antennas is a holder which ensures:
• fixing of the antenna to the mast
•
flexibility in two planes (necessary for antenna adjustment to the proper direction).
Each holder allows at least 2 methods of mounting antenna on the mast tube:
• right-side mounting
• left-side mounting
Following sections describe in detail installation of antennas, mounting kits and/or flexible waveguides,
so the antenna is ready for mounting RAy unit to it. Choose below a chapter relevant for your antenna
supplier and installation manual according to antenna type and size.
Note
Each antenna allows RAy unit to be mounted on it with horizontal or vertical RX polarization.
This is discussed in detail in Section 4.3, “RAy unit mounting”.
4.2.1. LEAX-RAy antenna mounting
Mounting instructions for each LEAX-RAy antenna are shipped with each antenna. Identical mounting
instructions are available within RACOM RAy download1section, on our website. See list below:

(same for all sizes). The RAy interface is part of each LEAX-RAy delivery (one interface set per
antenna). It needs to be mounted to each antenna according to the instruction manual before
mounting the RAy unit. Four pcs M8x30 (Allen) screws to mount the RAy unit to the antenna are
also part of the antenna delivery.
Item ANT-LEAX-STRUT-90 (for 90 cm antennas) respectively ANT-LEAX-STRUT-120 (for 120 cm
antennas) allows to increase operational wind speed up to 65 m/s (instead of 50 m/s respectively 55
m/s). Also allows to use tower pipe Ø50-120 mm (instead standard Ø90-120 mm).
Ensure the pin lubrication is completed during assembly.
4.2.2. Jirous antennas mounting
Mounting instructions for Jirous antennas are available on the manufacturer's website http://en.jirous.com.
Mounting is also described in detail on RACOM RAy download9section:

4 pcs M8x30 (Allen) screws to mount the RAY unit to the antenna are part of the antenna delivery.
Item SET-JRMB-1200-FIX or SET-JRMB-1200-ADJ (optional wind bracing sets, both for 120 cm antennas) allows to increase operational wind speed for extreme sites.
Ensure the pin lubrication is completed during assembly.
4.2.3. Other antennas mounting
Antenna which do not have a direct interface to RAy needs also a proper antenna mounting kit or a
flexible waveguide with a mounting kit for it. Such interface has to be installed prior to RAy unit installation to the antenna.
Antenna mounting kit can be ordered as an accessory part (one per antenna). It has to be chosen according to selected band and antenna vendor - see Overview of currently available types. Any other
antenna can be connected to the RAy by standard flexible waveguide. RACOM offers mounting kits
(RAy holders) for different flexible waveguides (see Accessories and the picture Flexible waveguide).
Standard mechanical tools are enough to install each of those accessories.
Items "SET-RAYxx-ARK" (where xx is the band) fits all traditionally produced Arkivator antennas (from
company Arkivator, acquired by LEAX Group) as well as today produced Arkivator antennas from
company LEAX Arkivator Telecom sold without RAy interface.
NOTE:
All LEAX-RAy antennas listed in the RACOM portfolio contain specific RAy interface and thus no
mounting kit is required.
Antenna mounting kit for Andrew antennas
Items "SET-RAYxx-ANW" (where xx is the band) fits most of Andrew antennas manufactured by
CommScope with specific vendor's interface unmounted. RAy3-17 and RAy3-24 need Dual polarized
antennas.
•
for 17 GHz band use SET-RAY17-ANW and order the following dual-polarized antenna types:
VHLPX1-18W/A30 cm
VHLPX2-18W/A60 cm
VHLPX3-18W/A100 cm
NOTE:
The antennas labelled for 17.700 - 19.700 GHz band are also OK for 17.100 - 17.300 GHz band
(confirmed by CommScope).
•
for 24GHz band use SET-RAY24-ANW and order the following dual-polarized antenna types:
VHLPX1-26W/A30 cm
VHLPX2-26W/A60 cm
VHLPX3-26W/A100 cm
NOTE:
The antennas labelled for 24.250 - 26.500 GHz band are OK for 24.000 - 24.250 GHz band (confirmed by CommScope).
NOTE:
Ordering codes with "-W/A" at the end means one of suitable types of waveguide (vendor's interface),
must be unmounted before installation of RAy antenna mounting kit. Ordering codes with "-GDC" at
the end means no vendor's interface, so nothing needs to be unmounted in such a case.
If there is a requirement to connect different type of antenna (for example some newer antenna type),
it is possible to modify the existing adapter to meet new requirements.
Flexible waveguide
Flexible waveguide mounting kit can be ordered as an accessory part.
Flexible waveguides themselves are not offered by RACOM - please consult your antenna supplier.
Ensure the pin lubrication is completed during assembly.
4.3. RAy unit mounting
RAy unit can be attached to several different models of antennas from several vendors. Installation of
RAy unit on to LEAX-RAy or Jirous antennas or to any other antenna through proper RAy mounting
kit (eventually with flexible waveguide) is very simple and it is identical for all antennas and mounting
kits. Installation starts with the lubrication of antenna pivot, followed by fixing the RAy unit in a proper
position to the antenna and finished by unit grounding to the mast – as described in following sections.
4.3.1. Lubrication of the antenna pivot
Before fitting the RAy bushing to the antenna pivot ensure the "O" ring (part No. 1) is in the correct
position. It is also essential to prevent moisture getting in between these two parts. This moisture could
cause oxidation which would complicate disassembly of this mechanical coupling in the future. For this
reason we need to treat these surfaces with the grease which is supplied in the box marked
"SILIKONOVE MAZIVO". If you use a different grease for lubrication then it should be a Teflon or a
silicon grease.
Fig. 4.5: Grease points on the antenna pivot and RAy unit bushing
Lubricate both the internal area of the bushing on the RAy unit (2) and the "O" ring (1) with a thin even
layer that allows the pin to slide easily into the bushing without damaging the "O" ring. The layer has
to be really thin and even to ensure no grease is pushed in to the waveguide. A little bit more grease
may only be applied in the area (3) beyond the "O" ring on the antenna pin to optimally fill the small
gap (max. 0.1 mm) between the pin and the bushing to prevent leakage of moisture and water into the
unit. Installation should be carried out according to the antenna installation instructions.
A tub of grease is supplied with each RAy unit.
Important
Lubrication is a very important assembly step for every
RAy unit. Failure to lubricate the unit can lead to operational and assembly complications.
Fig. 4.6: Silicone grease
4.3.2. RAy unit mounting to the antenna
Each antenna allows RAy unit to be mounted on it with different polarization:
• horizontal TX polarization
• vertical TX polarization
Fig. 4.7: Horizontal and vertical TX polarization – see the arrow sign
In all cases mount the unit with the connectors facing downwards at an angle.
Note
RAy3 links need one unit to be installed with vertical polarization and the other unit with
horizontal polarization because these units use cross polarization.
Fig. 4.8: RAy3 unit with antenna (left-side mounting and horizontal polarization)
RAy unit is fixed to the antenna by 4 pcs M8x30 (Allen) screws, which are part of the delivery of each
antenna or each mounting kit. Those should be partially unscrewed so that the unit can be slid on to
them. Then check whether the "O" ring is correctly fitted on the antenna pin, and make sure it is not
damaged and has been lubricated with grease – see Section 4.3.1, “Lubrication of the antenna pivot”
above.
Then remove the protective plastic cover from the central pin of the antenna and fit the unit flange
(located in the center of flat part of RAy unit, across the holder) to it carefully not to damage the "O"
ring. Once the RAy unit is plugged to the antenna pin, turn RAy clockwise so its screw-holders fit the
right position for all 4 screws. Carefully ensure the correct polarization of the unit – see Section 4.3.2,“RAy unit mounting to the antenna” and secure the RAy unit in place with all four bolts. Finally, gently
tighten the bolts with a No. 6 Allen key.
Important
Gently tightening all 4 screws is enough. Do not over-tighten any screw, it may damage the
protective color surface of the aluminum unit (enforcing corrosion processes) and in the
case of an extreme force also deformations of the RAy aluminum cover may happen. Later
de-installation of the unit then becomes difficult.
Please ensure that all 4 screws are tightened equally during tightening and the gap between
RAy screw-holders and spacers on all 4 sides of the RAy unit is approximately identical.
Too strong tightening of one or 2 screws on one side of RAy unit may lead to the deformation
of the sensitive zone of the waveguide between the antenna and the unit, resulting in
weaker radio parameters.
Even a small residual gap between RAy unit and the antenna is OK, because important is
a good connection of waveguide – it is good enough even with screws gently tightened.
NOTE: on older LEAX-RAy antennas (shipped during the year 2017) the residual gap under
each screw-holder on RAy and antenna body may be up to 1 mm.
4.3.3. RAy unit grounding
RAy unit has to be properly grounded, otherwise it can not be guaranteed its function and it can be
even damaged. Grounding connection through antenna and its holder is not enough (due to color surface,
oxidation etc.), thus a separated grounding is required to ensure the perfect galvanic connection.
The RAy unit has to be grounded before connecting to the power supply and/or to the user
network.
Typically the unit is grounded to the antenna mast, which has to be properly grounded (according to
Fig. 4.19, “Grounding installation 1” and Fig. 4.20, “Grounding installation 2”, where unit grounding to
the antenna mast is marked by yellow-green cable).
The RAy unit is grounded to the flange at the fixing screws using an M8 screw. An insulated copper
cable with a minimum cross-section of 6 mm2terminated with a terminal lug is used as a protective
conductor. The conductor should have a green/yellow plastic cover along its whole length. The RAy
grounding kit can be ordered as an accessory (see Chapter 2. Accessories) containing a grounding
terminal ZSA16, 40 cm grounding strip 15 mm wide, and 100 cm of cable with grounding lugs. For instructions on installing terminals see the datasheet RAy grounding kit11. The antenna must be installed
by a qualified person.
Properly installed unit grounding kit (from RACOM accessory) is documented on photos below.

Fig. 4.11: RAy grounding kit
Fig. 4.12: Protective conductor at the mast
on a ZSA16 terminal
The unit is equipped with 3 standard connectors described in detail (including connectors’ pin-outs) in
Section 1.3, “User interfaces” and Section 1.4, “Service interfaces”. Use only standard counterparts to
these connectors.
Fig. 4.13: Slots ETH1+POE, ETH2Fig. 4.14: Slot S
A set of standard bushing and plugs is delivered with each RAy unit as an accessory SET-RAY3- CON.
The rubber sealing for each bushing is delivered with three different internal diameters to fit different
cable diameters. The rubber is diagonally cut to enable sealing of cables with pre installed connectors.
If the lengthening of the bushing is needed use the short extension SET-RAY2-EXT35 (adds 35 mm
length, parts No.6 + No.7 on pictures below) or the long extension SET-RAY2- EXT-F50 (adds up to
50 cm).
Important
Before connecting the RAy unit to the power supply and/or to the user network it must be
grounded according to Section 4.3.3, “RAy unit grounding”
All cables have to be secured by appropriate bushings which must be fitted with relevant
O-rings and carefully tightened in, according the instructions below.
Remaining connector slots on RAy unit has to be secured by plugs (including the original
plugs in the flanges). Those must be fitted with O-rings and carefully tightened as well.
Otherwise, the unit is not protected against moisture intake through connectors and can not
guarantee unit functionality.
Fig. 4.15: Short bushing assembly for
metallic Ethernet with short ETH connector
Fig. 4.17: Bushing including short lengthening (for metallic Eth with longer connector or for non-OFA
fibre optic cable)
• Put on the cable: the nut No.1, rubber sealing No.2, bushing No.3 and O-ring No.4.
(If you use extension ring No. 6 with O-ring No.7 put those on the cable as well.)
• Attach the appropriate connector No.5 to the cable.
• Plug the connector No.5 into the RAy3 unit.
(If you use extension ring No. 6 with O-ring No.7, lubricate its thread with grease and screw those
into the RAy3 unit.)
• Screw the bushing No.3 with the sealing O-ring into the RAy3 unit.
• Move the rubber sealing (2) along the cable to fit in the bushing. Screw the nut (1) on bushing (3).
• (If you use extension ring No. 6 with O-ring No.7 lubricate its thread with grease.)
Practical tip: Screw the ring No.6 and bushing No.3 quote tightly, so they could not rotate
when the nut No.1 is screwed (or released later on). Not doing so could damage the cable
by twisting it during sealing. It can also create the issue later on when the nut No.1 is released
(and ring No.6 or ring No.3 releases first).
• Unscrew the bushing No.3 with O-ring No.4 (and extension No.6 with O-ring No.7).
• Remove the connector.
Warning
It is absolutely critical first to completely release and disassemble the nut No.1 and remove
the rubber No.2. Failure to do so could cause the damage of Ethernet cable or fibre optic
wire by cable rotation. Even connectors inside the RAy unit can be damaged. Should the
rubber sealing No.2 become fastened to the cable and/or to the plastic bushings, the rubber
sealing must be detached from the cable by a brute force. We suggest you use a flat screw
driver to release the rubber sealing No.2.
It is always better to optionally damage the bushing rather than damage a cable or
components inside the RAy unit.
At the outer end of the long lengthening there is necessary to use a flat ring supplied as part of the
SET-RAY2-EXT-F50. On other places O-rings are used. See next Figure:
Fig. 4.18: Bushing including long lengthening
Important
When using other bushing or connector than the delivered there is a danger of bad seal
•
or damaging the connector. Interior space can be small.
The proper grounding together with surge protection components should be installed on site to increase
the resiliency of the whole installation against natural overvoltage situations (stimulated by storms,
lightning and other atmospheric issues). Such a system has to respect local standards for grounding
and electromagnetic protection, otherwise the risk of damage of the unit and/or connected IT infrastructure gets much higher. We also recommend to consult each site situation with local experts to ensure
the installed grounding is enough for the actual site conditions and that the overvoltage protection of
sensitive components or infrastructures is reasonably effective against typical situations on site.
The rule is that every metallic component of wireless infrastructure located outside the building (in
LPZ0) should be properly grounded and protected against overvoltage, especially:
•
grounded RAy unit itself (as described in Section 4.3.3, “RAy unit grounding” )
• grounded all shields from all metallic Ethernet cables
• grounded all DC cables (shields or one wire)
• overvoltage protection is applied on all metallic Ethernet cables at the point of entrance to the building
• overvoltage protection is applied on DC cable at the point of entrance to the building
All types of cables should be grounded and longer cables should be grounded in several places (outside
the building every few meters). Overvoltage protective devices are available for all types of cables and
usage. Accessories offered by RACOM for those purposes are listed in Section 2.1, “Overview ” and
described in detail in Section 2.2, “Details ”
Important
The unit and mast must be properly grounded before the power supply and/or the user
network are connected to RAy unit.
Warranty does not apply for units destroyed by surges or over-voltage (see RACOM warranty
conditions at Section 10.6, “Warranty” ).
Note
Some PoE power sources, PoE injectors and DC power supplies have overvoltage / surge
protection built in. Please consult the datasheets of those versus the local standards and
site requirements.
On sensitive sites additional overvoltage protection should / could be applied between different zones (or rooms) even within one building (for example between network center and
datacenter).
LPZ acronym means Lightning Protection Zone.
The example and rules below are designed in accordance with regulation EN 62305.
1. Where possible the antenna should be located in an LPZ 0B protection zone with the use of a local
or artificial air termination device for protection against direct lightning strikes.
2. When meeting conditions for ensuring electrical insulation (distance from the lightning conductor)
in accordance with article 6.3 of this standard, it is not recommended to ground the load-bearing
structure and antenna to the external air termination network. Grounding should be attached to the
protective system of the internal LV (Low Voltage) wiring or grounded internal structures using a
CYA 6 mm2bonding conductor , see Fig. 4.19 Grounding installation 1.
3. If it is not possible to set up conditions of electrical insulation in accordance with article 6.3 of this
standard, we recommend connecting the load-bearing structure at roof level to the external air termination network via an 8mm diameter FeZn conductor and shielding the data cable before entry
to the building with a grounding kit and CYA 6 mm2conductor to the bonding bus, and if not already
set up then also to the external air termination network, see Fig. 4.20 Grounding installation 2.
4. If there is not an external LPS on the building we recommend routing lightning current through an
8mm FeZn conductor to a common grounding system, or to a separate grounding electrode with a
ground resistance up to 10 Ω.
5. For limiting the overvoltage transferred over the data cable and into the building we recommend fitting
surge protection at the interface between zones LPZ 0 and LPZ 1 connected via a CYA 4 mm
conductor to the same grounding point as the antenna or the antenna mast.
6. We recommend protecting the PoE power supply from overvoltage on the LV side with suitable class
D surge protection.
Racom supplies surge protection for installation on Ethernet cables entering buildings. For more details
see Surge protection12.
Additional safety recommendations
• Only qualified personnel with authorisation to work at heights are entitled to install antennas on masts,
roofs and walls of buildings.
• Do not install the antenna in the vicinity of electrical wiring. The antenna and bracket should not
come into contact with electrical wiring at any time.
• The antenna and cables are electrical conductors. During installation electrostatic charges may build
up which may lead to injury. During installation or repair work to parts of the antenna lead, bare
metal parts must be temporarily grounded.
• The antenna and antenna cable must be grounded at all times.
2
• Do not mount the antenna in windy or rainy conditions or during a storm, or if the area is covered
with snow or ice.
• Do not touch the antenna, antenna brackets or conductors during a storm.
NOTE: It is always better not to install the microwave unit directly under the lightning conductor holders.
There is lower probability of unit being polluted by birds.
It is necessary to install the Ethernet lead so that there is no excessive mechanical stress applied on
the connector bushing:
Fig. 4.26: Example of a correct lead installation.
4.6. Power supply
RAy microwave unit can be powered by active PoE, passive PoE or by DC power source. All variants
of power are supplied through RJ45 Ethernet connector (in slot ETH1+POE). Detailed description and
technical parameters of the connector is described in Section 1.3.1, “RJ45 ( ETH1+POE )”.
RACOM is offering all kinds of power supplies, all guaranteed for compatibility with RAy unit and tested
for long-term stability – they are listed in Section 2.1, “Overview ” and described in detail in Section 2.2,“Details ”.
4.6.1. PoE power sourcing
• Active PoE plus (called also Standard PoE+) power supply compatible with IEEE 802.3at, sourced
by AC or DC power. The standard IEEE 802.3at defines negotiation method, wires to be used, operating voltage (36-56V), maximum supported current, overcurrent protection and other parameters.
Any power supply compatible with IEEE 802.3at standard can be used.
• Passive PoE power supply (called sometime PoE injector), is an equipment pushing to the pins of
Ethernet connector DC power with a polarity and voltage compatible with IEEE 802.3at standard.
Thus, supported voltage, distances, grounding and internal RJ45 pins wiring are identical with
Standard PoE+ (mentioned above). Typically, the current is sourced from a DC power with adequate
parameters (voltage 40-60V, max current at least 1A). The only additional requirement is that nongrounded wire of DC power circuit in the PoE injector has to be secured by a fuse disconnecting the
power circuit in the case of over current (similar like for DC power source connected directly to the
RAy unit by a DC connector).
Note
Quality CAT7 Eth cable (i.e. shielded one) with UV protection is recommended for outside
use.
Quality connectors (like CON-RJ45-TLG-CAT6) are recommend to be used on both ends
of Ethernet cable to ensure long-term reliability of the connection. Such connectors have
better resistance against oxidation and also against scorching contacts due to spikes
during power-on and power-off the unit by plug / unplug Ethernet cable. Anyhow standard
Eth cable with standard Eth connectors should work as well.
Overvoltage protection unit is recommended to be applied between RAy unit and PoE
power supply – for details see Section 4.5, “Grounding and overvoltage protection” (easily
visible on Fig. 4.19, “Grounding installation 1”).
4.6.2. DC power sourcing
Direct DC power input for RAy3 unit described in Section 1.3.3, “DC power ( ETH1+POE )” requires
the use of DC-RJ45 adapter.
• Any kind of DC power source with supplied DC voltage in the range 20-60 V and with enough power
for the RAy unit plus energy loss on the DC cable. (For RAy3-17 and RAy3-24 the minimum is 25
Watts). If a longer DC cable than few meters is used, then Watts of power supply has to be adequately
higher to cover the power loss within the DC cable.
• RAy3 internal DC power circuits accept both polarities and they ensure galvanic separation of power
source line from the RAy unit itself. This simplifies the DC power circuits installation.
• The DC power circuit must be fitted with a fuse to protect against short circuiting (or power supply
has to have such a fuse built-in).
Typically, DC wires have cross-section 1.5 mm2. DC contacts on DC-RJ45 adapter are
designed for this cross-section.
•
DC-RJ45 adapter occupies ETH1+POE port on RAy3 unit. When used, Ethernet connection
to the unit has to be made through ETH2 port. Possible solutions are described in section
NOTE at the end of Section 1.3.3, “DC power ( ETH1+POE )”.
• If shielded DC power cable is used, then shield should be grounded by a proper
Grounding kit to the mast or directly to the Grounding screw on RAy unit.
• If the galvanic separated power source is used and the DC power line needs to be
grounded (either positive or negative wire), the connection of one DC line to the ground
should be made by a proper Grounding kit to the mast. Possible is also to use a small
piece of DC cable to connect the line to be grounded directly to the Grounding screw on
RAy unit. For more details see Section 4.5, “Grounding and overvoltage protection”.
Connect a power supply to the installed RAy unit. Connect the device to be used for configuration via
WiFi or ethernet cable. Access the configuration menu using browser or Alignment tool.
4.7.1. Noise on the site
This is particularly true for installation of links working in free bands, where the user has no secured
frequency.
Analyse the level of noise in the individual channels using the spectrum analyzer under Tools/Livedata/Frequency spectrum analyzer. If necessary adjust the choice of working channel on the basis of
the results.
While doing so respect the rule that in one location all units emit a signal in the Upper part of the range
and receive it in the Lower part of the range, or the other way round. A transmitter must not be installed
in the part of the spectrum where other units function as receivers.
4.7.2. Directing antennas
• For first antenna alignment, use a narrow channel, low modulation and high power where possible.
• ATPC and ACM functions should be switched off (prevents Tx power fluctuations during alignment).
• Where possible adjust both ends of link simultaneously to speed up the process.
• Alternate adjustments at both ends of link in small increments both horizontally and vertically to establish position with strongest signal whilst looking for maximum main signal (see paragraph on main
& side lobes).
• RSS measurement chapter provides overview for available methods to measure RSS.
RSS measurement
To align antennas accurately connect a PC, tablet or mobile and use the diagnostic and measurement
capabilities built in to the RAy unit. There are 4 tools available to support measurement of the 2 basic
parameters for optimum antenna alignment: RSS (Radio Signal Strength) and SNR (Signal to Noise
Ratio):
1. Voltmeter – indicates local RSS
2. RAy Tools smartphone application – indicates RSS, SNR - Local & Peer
3. Antenna Alignment Tool web page – indicates RSS, SNR – Local & Peer
4. Bar graph on Live Data page inside web manag. – indicates RSS, SNR, BER – Local & Peer
Before antenna alignment starts it is recommended to find out RSS and SNR values from the link design
for the installed link or calculate these values yourself. There are 4 methods available with increasing
levels of accuracy:
•
Module Calculation inside RAy Tools smartphone application
•
Link calculation on RACOM website
13
• Use Link calculation chapter in Application notes
• Precise link calculation using dedicated tools (e.g. Pathloss)
RAy units support traditional antenna alignment using a voltmeter measurement representing RSS in dBm (only for a
local unit). Connect a voltmeter with the range 2V DC via
connectors to the operational unit and adjust antennas to the
lowest indicated voltage. Voltage is calibrated according to
signal strength. E.g.:
RSS -65 dBm corresponds to voltage 0.65 V,
RSS -80 dBm corresponds to voltage 0.80 V etc.
RAy Tools – smartphone application
RAy Tools is an application described in detail in Chapter 7.
RAy Tools app for Mobile devices . Module Alignment displays
RSS and SNR for both local and peer RAy unit. All key functionality in this module performs an identical function to Antenna Alignment Tool described in Section 5.6.2 Live data .
More about RAy Tools in Chapter 7. RAy Tools app for Mobiledevices .
Antenna Alignment Tool – html page within unit management
Antenna Alignment Tool is optimized for devices with smaller
displays. All values are refreshed ten times per second to
enable smooth operation. The Antenna Alignment Tool is described in Section 5.6.2 Live data . The Tool is available on
http://<ip>/tk, (e.g. http://192.168.169.169/tk for standard
Ethernet ports, alternatively on http://172.17.17.17/tk in the
case of connection through USB/WiFi or USB/Eth).
The Tool is accessible without any username or password.
Bar graph in web management
Within user management Tools / Live data / Bar indicators
shows bar graphs of RSS, SNR and BER (Bit Error Rate)
values for local and peer units. Values are refreshed every
second or manually. See Section 5.6.2 Live data . for detailed
information.
NOTE: The BER value should be close to zero after antenna
alignment.
Directional antennas have a specific angle within which radio waves can be transmitted or received
(Angle of Tx/Rx).
The strongest signal is emitted in a forward direction; the main lobe is a graphical representation of its
direction of travel and strength. However signals are also emitted and received from unwanted directions
through side lobes. In receiving antennas this is a highly significant factor contributing to the level of
interference in a radio network (See Antenna lobe diagram ).
Fig. 4.28 Signal strength graph provides an indication of comparative signal strength from different
beams emitted from a directional antenna.
Fig. 4.27: Antenna lobe diagram
Fig. 4.28: Signal strength graph
Placing the antennas to the correct antenna alignment is very important to ensure the strongest signal
is received:
Both antennas should be oriented towards each other using the peaks of the radiation diagram. Adjust
the antenna alternately in the horizontal and vertical axes and monitor the resulting signal strength.
Use the calculation of the expected RSS with the precision of several dBm as guidance. Side lobes
transmit a signal ca 20 dBm weaker, see the Microwave link Calculation14.
The resulting RSS helps distinguish between
the states A-A and C-C which appear similar.
It also helps in situations where simple search
for a maximum doesn’t work as shown in the
illustration “incorrect adjustment”.
Real radiation diagrams are more complex,
especially in that they run differently in horizontal and vertical axes. The basic steps for determining the main radiation lobe however stay
valid. For example:
Basic parameters of the link are shown in the menu Status/Brief, its quality is characterized by RSS
and SNR. Values on Status screens can be refreshed manually by pressing the Refresh button or
in real time with a period of several seconds after activating the Start button. Press the Stop button to
terminate the periodic refresh of values.
The RSS, SNR and BER values can also be viewed on the screen Tools/Live data/Bar indicators. After
pressing the Start button, values will be refreshed with a period of one second.
After installation, it is good to reset the statistics using the Clear stats button in menu Status/Detailed.
This allows easier diagnostics of the link’s reliability over time.
4.7.4. Parameters setup
After both antennas have been aligned, setup operation parameters for the link. In the case of links
operating in the free band, setup the parameters based on survey results from the tool Tools/Live
data/Frequency analyser. In the case of links operating on a licensed band, setup the parameters based
on the assigned license:
• Bandwidth
• Channel Selection (TX / RX channel)
• Modulation (TX modulation) – ACM is recommended. When selecting fixed modulation it is necessary
to account for the fade margin. If fixed modulation is setup close to a possible maximum, then a deterioration in RSS could endanger the link both for data transfer as well as service access.
Restart both units by interrupting their power supply and verify the status of the link. This verifies that
all parameters have been stored correctly in the memory.
Select Tools/Maintenance/Backup/Settings (Local & Peer)/Full and save the configuration to backup
file “cnf_backup.tgz”.
This completes the installation. Further configuration can be performed remotely.
The following configuration buttons are used for configuration:

Enable automatic control of modulation.
Modulation level for TX channel. You can select in range from QPSK (high
sensitivity for difficult conditions) to 256QAM (high speed under appropriate
conditions). With ACM enabled the modulation will automatically operate
from QPSK to the selected modulation.
Enable automatic control of RF power.
Power is regulated towards lower level while maintaining signal level high
enough not to affect current degree of modulation.
The ATPC algorithm controls the output power according to RSS of the
peer unit. The lowest allowed RSS (the threshold) is approx. 10 dBm above
declared sensitivity for BER 10-6. If necessary, it is possible to use this
parameter to move the threshold slightly up or down.
RF output power. With ATPC enabled this parameter defines maximum
RF power level.
Gain of used antenna. It is used to calculate approximate EIRP.
Valid only for RAy2-17 and RAy2-24 links.
Approximate calculation of EIRP. Number on the right shows the allowed
EIRP limit. Sign between numbers gives information on compliance /
noncompliance with allowed EIRP limits. If the EIRP limit field background
is RED, the value shown may be used but will exceed the EIRP limit.
This field value will only be shown for certain RAy2-17 and RAy2-24 links
and based on the Frequency tables used.
The principle behind ATPC is to maintain the lowest transmitting power without affecting the throughput
of the link. The output is primarily controlled by RSS on the opposite side. ATPC is also used to maintain
SNR thus protecting the selected modulation level.
The ATPC Control loop is evaluated once per second.
The principle behind ACM is to maintain the connection between the two units even when degraded
propagation conditions are experienced which make it impossible to maintain the selected modulation
level. ACM regulates modulation across all ranges from QPSK to TX modulation according to the limits
in table ACM switching according to SNR state.
ACM control loop is evaluated with each frame, i.e. roughly after tens of microseconds.
In normal operating conditions, ATPC is applied first (even if it is the slower control loop). When deterioration in propagation conditions gradually increases the attenuation on the route, it is compensated
by increasing RF power. ACM control will only be applied in conditions when ATPC reaches its ceiling.

Service
channel
There are two modes of accessing the internal management system of the microwave
link: standard and direct
standard:
Both units are configured with the separate IP addresses, Netmasks, Gateways and
Management VLANs. IP addresses of both units does not have to belong in to the
same sub-net. The "Internal VLAN" is required to encapsulate the internal service
traffic between both units of the microwave link. There are additional internal service
addresses used for this internal service traffic (see "IPv4 address - Local" section for
further details).
direct:
Both units are configured with the separate IP addresses but with the same Netmask,Gateway and the Management VLAN. IP addresses of both units must belong in
to the same sub-net. There is no need for "Internal VLAN" to handle the internal
service traffic between both units of the microwave link. No additional internal service
addresses exist.
NOTE: It is strongly recommended to use "Management VLAN" to encapsulate and
prioritize the management traffic when the direct mode is selected. If the "Management
VLAN" is not used (while in direct mode), the internal service traffic is NOT prioritized.

Service IP address, by default 192.168.169.169 for L unit and 192.168.169.170 for U
unit. Four addresses 169.254.173.236/30 are used for internal communication. Must
not be used as service IP address. Those four addresses are not used while "Service
channel" is set to "direct" mode.
If you forget the Service IP address, it can be found by reading data broadcast through
LLDP protocol. Data is transmitted every 60 seconds and contains the following information:
IP addressManagement address
Serial numberSystem Description
Type (e.g. RAY2-17-L)Chassis Subtype
IEEE 802.1 - Port and Protocol VLAN ID
Port and Protocol VLAN Identifier: (e.g. 300 (0x012C))
but only if Management VLAN is enabled
The message can be recorded and converted into a readable form using an LLDP client.
A suitable tool for this purpose is Wireshark IP traffic analyzing tool, with free licenses
available for both Windows and Linux. To locate the message easily, use the Capture
filter "ether proto 0x88cc" in Wireshark.

Enables access via VLAN management. Blocks access for https, ssh and telnet con-
figuration via untagged packets (without VLAN) making only VLAN access possible.
VLAN management is off by default.
WARNING:
By enabling VLAN management, ALL accesses are blocked for configuration using
normal (untagged) LAN! During tests, you may enable VLAN management on one
unit only (if the "Service channel = standard"). Then it is possible to access the link
via LAN and VLAN either directly or via radio link.
VLAN management id, by default 1. This field must have a value entered even when
VLAN management is not active.
Protocol 802.1q or 802.1adProtocol
Valid only for "Service channel = standard": The RAy uses one VLAN id for internal
service communication between both units.
There are two situations when it might be necessary to change the Internal VLAN id:
- Conflict within user data flow when the same VLAN id is already present within a
data flow.
- Conflict with the internal management address of another RAy unit located at the
same site and connected in the same LAN segment.
NOTE: The Ethernet frames within this service channel are marked with IEEE 802.1p
priority class "7". Default parameters for QoS and Egress queue control are pre-set
to prioritize this service communication channel.
Allows access via web server (for HTTP and HTTPS protocol).
WARNING: after disabling access via web server, you will not be able to access the
unit using a web browser!
Enables access via telnet protocol. Provides access to CLI (Command Line Interface)
for simple telnet clients. Disabled by default.
Enables access via SSH protocol. Provides secure access to CLI. If preventing unauthorized access to the unit is the number one priority, leave only this server on.

this option.
Data transmitted through the LLDP protocol can be accessed in two ways:
Transmissions every 60 secondsOn
Transmitted once only when unit is rebootedSingle
See "IPv4 address - Local ... Unknown IP address" for description of the data transmitted through the LLDP protocol.
The USB connector is used for management access (not for user data) to the local unit using Ethernet
or WiFi adapter. Only RACOM recommended adapters are supported.
Default WiFi IP address of the unit is 172.17.17.17 with DHCP enabled by default allocating IP address
automatically to connected device.

USB to WiFi adapter is only activated during Air-Link loss – means WiFi
starts to work and transmit SSID. WiFi is activated 60 seconds after AirLink loss and deactivated 600 seconds after the Air-Link is restored. The
WiFi passphrase should be set by admin before using this option (if not
WiFi management alarm is activated).
USB to WiFi adapter is forced to be permanently active (and to transmit
SSID) and WiFi management alarm is activated. WiFi passphrase should
be set by admin before using this option.
This parameter has a higher priority than "WiFi adapter enable on Air link
loss", so if it is set ON then WiFi activity does not depend on Air-Link status.

Service WiFi encryption is WPA2 and can not be changed. Factory default
is "none" due to missing passphrase. WPA2 is applied automatically once
any passphrase is entered.
Service WiFi passphrase has to be 8-64 characters long. The WiFi passphrase should be set by admin before any use of WiFi. Until passphrase
is set, WiFi management alarm is activated.

Note
When upgrading from FW older than 2.1.28.0 it is necessary to click "Show Defaults" followed
by "Apply" to enable smooth WiFi functionality.
WiFi channel can be set 1-11 depending on WiFi mode setting (see parameter above):
IEEE 802.11n - channels 1-7
IEEE 802.11g - channels 1-11
The WiFi adapter does not search for conflicts in the air. If problems occur,
changing the channel is the easiest way to resolve the issue.

Fig. 5.11: Menu Link settings / Service access / Users
Configuration
Within the default Factory Settings one user is defined in the system. This user has username admin
and password admin and is assigned the highest level of permissions cli_super. This user then
assigns other users to the system along with their level of permissions.
Service access has three levels of permissions. Numbers of users that can be defined in the system:
No of usersPermissions

The logged on user is shown in the top right of the screen. There can be different users on either end
of the link.
Important
It is strongly recommended that the default password admin is changed. Similarly all other
users should change their password. Using the CLI, it is appropriate to supplement the SSH
key.

If two or more users work concurrently on the unit any change of configuration settings
should be applied by all users. This applies to the menu Link settings which works with both,
Local and Peer parameters. Notification to other users:
If one user sends the Apply command, other users will receive a message: "Configuration
changed, please go to Link settings and click Refresh". Other users can only use the Apply
command after refreshing Link Settings.
Clicking "Edit" next to a username opens a screen with configuration of the given account.

The diagnostics system of the link monitors the operation of the unit.
It generates various event outputs - system warnings and alarms. The event is always written to the
system log and indicated in the status bar and Alarms/Status screen. Some events have adjustable
thresholds. Events with no adjustable thresholds may or may not be Enabled. If they are not Enabled,
the system event is not activated even if the system status is changed.
If the event goes above or below the set parameter limits or a link goes down or up, you can choose
to send an SNMP trap. All SNMP traps are OFF in defaults.
