1. Product
1.1. Main characteristics
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).
Fig. 1.1: RAy3 – Microwave link
This link is formed by two RAy units, each equipped
by its own parabolic antenna and accessories to be
fully operational.
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.
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°. Therefore it transmits and receives using opposite
polarization with respect to the second unit. 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.
Note
All units for selected band 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 by using default
radio parameters.
Ethernet concept
RAy links are transparent for IP and UDP Ethernet traffic. Practically all protocols pass through including
MPLS, RSTP (BPDU frames) and many others, except following:
• Management packets targeted for RAy units itself
RAy3 Microwave Link – © RACOM s.r.o.12
Product

• 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. PIRL, QoS, EGRES shaping ...)

1.2. Mechanical interfaces
This chapter describes basic properties of each RAy unit, which are important for its mechanical install-
ation: antenna waveguide, unit fixing (screws, etc.) and unit grounding (screw + cable). Other interfaces
(for data, power and service purposes) are described in next chapters Ethernet + power interfaces and
Service interfaces.
1.2.1. Antenna waveguide
Antenna waveguide flange on RAy unit (located across the holder) ensures perfect microwave connection
between the unit and the antenna.
RAy3 link requires use of external parabolic antenna for each RAy unit – both for physical mounting
as well as for the wireless transmission itself. Parabolic antennas1from different producers are available.
Fig. 1.2: Waveguide pivot and flange
Important
Before assembling RAy unit with antenna, always carefully lubricate both antenna waveguide
pivot and RAy waveguide flange with thin layer of silicone grease to prevent the damage of
O-ring and surfaces. Pivot fits smoothly in to the flange, if it is properly lubricated. A box with
silicone grease is packaged with each delivery of new units - see Section 1.6.3, “Packaging”.
Note
If O-ring is injured or damaged, please exchange it immediately for a new one (size 22x2 mm,
type 'FPM80'), otherwise moisture + dust can leak into the waveguide and emitter. It may
eliminate several dB of signal and cause a corrosion.

1.2.2. Unit mounting
RAy unit is mechanically fixed to the antenna by 4× 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 4× M8×30 (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
Section 4.7.2, “Directing antennas” .
Fig. 1.3: Antenna and RAy3 unit
1.2.3. Grounding screw
Fig. 1.4: Grounding screw
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 symbol and 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.

Pressure equalization between outside and inside of RAy
unit is an important technical requirement. It is realized by
a small plastic screw next to ETH2 label. It ensures the
pressure equalization without letting moisture or humidity
to enter the unit.
Important
Do not manipulate or remove this small plastic
screw. It is part of the cabinet and its manipulation
or a deformation can damage the water protection
of the unit.
Warranty does not apply for units with this screw
missing or deformed.

1.3. Ethernet + power interfaces
This chapter describes interfaces for user data transfer and power sourcing of the unit, as described
on the picture and characterized in the table below. Remaining interfaces for service purposes are
described in next chapter Service interfaces.
Fig. 1.6: Slots ETH1+POE, ETH2
FunctionSlot
Gigabit metallic Ethernet + Power over Ethernet (PoE) port
ETH1+POE This port is capable of powering the unit with any PoE power source working ac-
cording to IEEE 802.3at standard.
Passive PoE from 20 to 60 V is supported (if DC input is required, it could be injec-
ted through this connector - the voltage range is identical: from 20 to 60 V).
Slot for user exchangeable SFP module
ETH2
A wide range of fibre optics Ethernet modules is available. Both single or dual
mode transceivers can be used. 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.
Note
A set of all necessary bushing parts are delivered with each RAy unit - see a description of
this standard basic accessory ACS-RAy32. 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”.
Important
All bushings and plugs (including the original plugs in the flanges) must be fitted with O-rings
and carefully tightened. Otherwise, the unit is not protected against moisture intake through
connectors and cannot offer guaranteed functionality.

1.3.1. RJ45 connector (ETH1+POE)
Fig. 1.7: RJ45 Ethernet connector
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 (within item ACS-RAy33), ready to be punched
to an Ethernet cable.
Higher quality and CAT7 compatible RJ45 plugs are
available from RACOM as well – see for example item
CON-RJ45-CAT74.
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 stand-
ard 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, both polarities
are supported. For RAy unit booting the minimum re-
quired voltage is 21 V (to prevent booting with discharged
24 V battery).
It is possible to use all 4 Eth pairs (8 pins) or only 2 Eth pairs (4 pins). Use:
• either 4,5 (V+) and 7,8 (V-) or opposite +/- DC polarity
• or 1,2 (V+) and 3,6 (V-) or opposite +/- DC polarity
• or both simultaneously (with all combinations of +/- DC polarities supported)
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 OTH-DC/RJ455).
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”.

1.3.2. SFP slot (ETH2)
Fig. 1.8: SFP slot
„ETH2“ is a standard SFP slot for 10/100/1000 Mbps Eth-
ernet 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 fibres) 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-
cessory6.
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 re-
ceived signal from the fibre optic or metallic link to be
within operational range.
Note
It is strongly recommended to use a high quality
SFP module with industry temperature range. The
SFP modules listed in Accessories7are thoroughly tested by RACOM and are guaranteed to
function with RAy units. It is possible to use any other SFP module with power consumption
up to 1.25 W, but RACOM cannot guarantee their complete compatibility with RAy units.
Important
SFP module has to be inserted to out-of-power unit, otherwise its function is unpredictable
and the module and/or the RAy unit can be damaged.
Do not remove the smaller plastic screw next to ETH2 label. It is part of the cabinet and assures
pressure equalization outside and inside.

1.3.3. DC power (using ETH1+POE)
Fig. 1.9: Power supply connector
Fig. 1.10: DC-RJ45 adapter
Direct DC power source can be used to power the RAy3 unit.
Instead of standard DC connector the DC cable is mounted to
a terminal block on DC/RJ45 adapter (item OTH-DC/RJ458).
The adapter is then fitted in to the RJ45 connector in slot
ETH1+POE.
Item OTH-DC/RJ459is orderable with the unit (see Sec-
tion 1.7.1, “ RAy units”). It is equipped by 2 terminals (each min
2 A / 1.5 mm2/ AWG 14) with screws to ensure perfect connec-
tion with cooper DC power cable.
Internal RJ45 pins wiring of DC/RJ45 adapter utilizes all
8 contacts on RJ45 and is:
• DC terminal (+) RJ45 pins: 1,2,4,5
• DC terminal (-) RJ45 pins: 3,6,7,8
• RJ45 shield floating (not connected to any pin)
Supported voltage range is 20 to 60 V, both polarities are sup-
ported. The minimum required voltage for RAy unit booting is
21 V (to prevent booting with discharged 24 V battery). Maxim-
um long-term voltage on RAy unit is recommended to be below 58
V (to ensure over-voltage protection inside the unit stays deactiv-
ated). 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 Grounding10 in section Accessories.
More information about DC power sourcing installation can be found
in Section 4.6, “Power supply”.
