RAy3 microwave units work as a wireless Ethernet point-to-point link in a full duplex setting with transfer speeds of up to 1010 Mbps. The link is formed by two RAy units, each equipped by its own parabolic antenna and accessories to be fully operational.
Supported are several license-free bands and several licensed bands, all in the identical alluminum box. Bandwidth can be configured from 3.5 up to 112 MHz, independently for TX (transmission) and RX (receiving). 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).

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 Section 18.104.22.168, “SW feature keys”).
HW models are determined only by frequency bands and in the case of licensed bands (i.e. 18 GHz) and RAy3-10 also by subbands. Additionally in 10 GHz, 18 GHz and 80 GHz bands units forming a link differs in HW duplexer which ensures the proper frequency separation of transmitting and receiving channels. This is marked on each unit as Lower (L) or Upper (U) in Production code according the position of transmitting channel.
Units for 17 and 24 GHz does not have any HW difference between L and U units, because 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.
All units for selected 17 or 24 GHz band are hardware identical. Default factory settings in the pair use different channels for L and U unit, so the link could be established by using default radio parameters.
RAy links are transparent for IP and UDP Ethernet traffic. Practically all protocols pass through unmodified including MPLS, RSTP (BPDU frames) and many others, except following:
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. PIRL, QoS, EGRES shaping …)
This chapter describes basic properties of each RAy unit, which are important for its mechanical installation: 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.
Antenna waveguide flange on RAy unit (located across the holder) ensures perfect microwave connection between the unit and the antenna. All RAy units are equipped with identicaly sized round flange (with the outer diameter 50 mm and the inner diameter 28 mm). The only visible mechanical difference between RAy models are the diameters of the round waveguide hole in the middle of the flange. Those diameters differs according frequency ranges and are following:
|10-11 GHz||19.00 mm|
|17-18 GHz||11.00 mm|
|24 GHz||8.00 mm|
|70-80 GHz||3.18 mm|
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 antennas from different producers are available.
Each antenna has to be equipped by a correspondingRAy antenna waveguide interface – the metallic pivot (28 mm diameter) with a rubber O-ring on it, otherwise the signal to/from the unit can not be transmitted from/to the antenna and such a link would not work.
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”.
If O-ring is injured or damaged, please exchange it immediately for a new one (size 22×2 mm, type ‘FPM80’), otherwise moisture + dust can leak into the waveguide and emitter. It may eliminate several dB of signal and cause a corrosion.
Antennas from Jirous, LEAX Arkivator and Shenglu ordered for RAy mounting are automatically equipped by RACOM RAy waveguide interface and are ready for mechanical fixing of RAy unit to the antenna.
Antennas from other vendors has to be equipped by a proper antenna adapter first. The adapter must be mounted on the antenna before the RAy unit can be mounted on it.
All available antennas and adapters are listed on RAy web pages in section Accessories > Antennas.
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” .
Antennas from Jirous, LEAX Arkivator and Shenglu ordered for RAy mounting are automatically equipped for mechanical fixing of RAy unit (including the delivery of 4× M8×30 Allen screws).
Adapters for antennas from other vendors always contain proper mechanical fixing of RAy unit (including the delivery of 4× M8×30 Allen screws). The adapter has to be mounted to the antenna first, the RAy unit is then mounted on this adapter.
All available antennas and adapters are listed on RAy web pages in section Accessories > 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 symbol and both are equivalent (second hole remains unused). For more information about unit grounding see Section 4.3.3, “RAy unit grounding”.
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.
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.
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.
|ETH1+POE||Gigabit metallic Ethernet + Power over Ethernet (PoE) port|
|This port is capable of powering the unit with active or passive PoE power source or with direct DC.|
|ETH2||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. 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 ACS-RAy3. 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 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.
RJ45 socket connector marked „ETH1+POE“ is a standard 10/100/1000Mbps metallic Ethernet port.
This port is also used for power sourcing the unit by PoE (Power over Ethernet) or direct DC power source. Both an active PoE power supply (compliant with IEEE 802.3at or IEEE 802.3bt standards known also as „PoE plus“) and a passive PoE power supply (with wider voltage range than PoE) are supported.
Technical parameters of PoE power input:
Supported voltage range depends on the maximum power consumption of each model:
20 to 60 V for RAy-10, RAy3-17 and RAy3-24 (for unit boot at least 21 V to prevent booting with discharged 24 V battery)
37 to 60 V for RAy3-18 and RAy3-80
Any polarity of DC and PoE inputs are supported.
Supported PoE types of power sourcing are:
Active PoE requires PoE power supply compliant with standards IEEE 802.3bt or IEEE 802.3at (the second one only for RAy3-17 and RAy3-24) and the reasonably quality Ethernet cable, otherwise the proper function of the unit can’t be guaranteed. The norm defines supplied voltage in the range 50-57 V and max current typically 0.55-2.0 A.
Passive PoE (as well as direct DC power sourcing described in Section 1.3.3, “DC power (using ETH1+POE)”) can operate in whole extended voltage ranges listed above.
RJ45 connector pins are wired according standards IEEE 802.3bt (utilizes 4 pairs = 8 wires) and IEEE 802.3at (utilizes 2 pairs = 4 wires). All RAy units support all PoE modes of operation:
Mode A: pins 1,2 (V+) and 3,6 (V-)
Mode B: pins 4,5 (V+) and 7,8 (V-)
Mode A+B: all 8 pins with numbers identical to Mode A and Mode B
Additionally to IEEE norm all RAy units can be powered by PoE or DC with opposite +/- polarity.
PoE with 8-wires is strongly recommended for RAy3-10, RAy3-18 and RAy3-80 due to their power consumption >25 W. PoE with 8-wires is recommended also for other RAy3 models to minimize the energy lost in the Eth cable (it lowers the resistance of the Eth cable to half compared with 4-wires PoE).
One plastic RJ45 plug for CAT5e and CAT6 cables is delivered with each RAy
unit (within item ACS-RAy3), ready to be
punched to an Ethernet cable.
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 fibres) can be used. CSFP modules are not supported. accessory.offers all mentioned types of SFP modules, tested to be RAy compatible as a standard
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.
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 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 cannot guarantee their complete compatibility with RAy units.
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.
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/RJ45). The adapter is then fitted in to the RJ45 connector in slot ETH1+POE.
Item OTH-DC/RJ45 is orderable with the unit
(see Section 1.7.1, “RAy units”). It is equipped by 2 terminals (each max 2
A / 1.5 mm2 / AWG 14) with screws to ensure perfect connection
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)
Both polarities are supported. Supported voltage range depends on the maximum power consumption of each model. Those are:
20 to 60 V for RAy3-17 and RAy3-24 (for unit boot at least 21V to prevent booting with discharged 24 V battery)
37 to 60 V for RAy3-18
Maximum long-term voltage on RAy unit is recommended to be below 58 V (to ensure over-voltage protection inside the unit stays deactivated). 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 in section Accessories.
More information about DC power sourcing 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 SFP module inserted in to ETH2 port. Standard SFP modules for fibre optic Ethernet or for metallic Ethernet (with RJ45 connector) can be used – see Accessories / SFP modules for more details.
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 over PoE through Ethernet cable with RJ45 connector plugged in to ETH1+POE slot as described in Section 1.3.1, “RJ45 connector (ETH1+POE)”.
Slot „S“ stands for “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.
|S||USB service connector|
|For USB/WiFi or USB/ETH adapters, see Section 1.4.1, “USB connector ( S )”|
|RSS voltage output|
|Red and green connectors (for example 0.547 V means RSS = –54.7 dBm),

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, “Service access” (part “USB Accessories”).
Only See USB adapters on RAy Accessories web site.recommended adapters are supported.
Each RAy3 unit is equipped with the service WiFi interface from the factory. It is realized by standalone WiFi module inserted in to the USB connector in slot “S”. WiFi can be used solely for unit management (no user traffic can be transmitted by using this WiFi connection).
WiFi module can be disabled in FW (WiFi module is out of power then) or manually unplugged. In both cases the results are identical – no WiFi is possible. Management of the WiFi port is described in Section 5.4.3, “Service access” (part “USB Accessories”).
RAy3 unit can be equipped with the service Ethernet interface as an option. It can be used solely for unit management (no user traffic can be transmitted using this Ethernet connection).
Optional Eth adapter (see RAy Accessories USB adapters web for available types) can be inserted in to the USB connector in slot “S” (instead of WiFi module). Management of this Ethernet port is described in Section 5.4.3, “Service access” (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.
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.).
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:
|Action to be performed||Unit status||Button pushed||SYS LED indication|
|Restore temporary stored |
customer settings (backuped previously to FLASH memory of the unit)
|For 5 seconds||Flashes Green|
to Local unit, then reboot
|Out of power||Pushed before power on, released after SYS LED stops flashing red||Flashes Red (delayed after power on, for a duration of 5 seconds)|
|Entering the |
(Please, exit this mode
by powering off the unit)
|Out of power||Pushed before power on, released when SYS LED starts flashing red||Flashes Red (delayed after power on)|
Those actions and their use are described in detail in Section 5.6.1, “Maintenance”.
RAy3 unit is equipped with one LED indicator located inside the housing of the
FOD unit in slot „S“ (during normal operation covered by semi-transparent plug). Meaning of
the color combinations of this LED indicator is:
||Unit is starting|
||Power source voltage is out of allowed range|
||System is up and working OK|
System reports warning or alarm,
||System reports HW alarm|
||Unit is out of power or HW button pressed|
Outer sizes for all RAy3 models are identical:

RAy3-17 2.6 kg
RAy3-18 2.9 kg
RAy3-24 2.6 kg
Basic technical parameters like identification of the HW model, working frequency, maximum RF Output power, requirements for power supply, most important certifications, etc. are visible on RAy Product label. All technical parameters are stated in detail in Chapter 9, Technical parameters.
The label contains identification of the HW model and its serial number, basic technical parameters, most important certifications, QR code to manual, address of the producer, etc. Meaning of the most important information listed on the product label is:
Type – RAy3 product line identification (for details see Section 1.7, “Ordering codes” )
Code – detailed identification of the unit HW (for details see Section 1.7.1, “RAy units” )
S/N – serial number, MW link consists of two separated units with two different serial numbers
QR code – www link to the latest version of the User manual
RF Power – maximum output power
TX, RX freq – range of working frequency
PoE – power supply characteristics
CE, FCC ID, IC or other – available certifications
The processor included in the unit variant S and X (identified by the item ‘Code’ on product label and in the ordering code) uses an encryption module listed as 5A002 a.1 in the COUNCIL REGULATION (EC) No 428/2009, setting up a Community regime for the control of exports, transfer, brokering and transit of dual-use items. Units are subject to export control when exporting outside the European union, according to national, EU and US law.
A link should consist from a pair of “-L” and “-U” units (L and U are always a last letter in Code printed on product label of each unit), but it is not mandatory for RAy3-17 and RAy3-24 (for those models HW for L and U unit is identical and L/U settings could be assigned by SW). Using L + U pair ensures all default settings of both units match each other (including proper IP addresses as described in this manual). It ensures the link is automatically established when received from the factory or after applying Default link settings or Factory settings (to simplify initial setting of the whole link).
The RAy3 radio link is supplied in a package containing two separate boxes. Delivery includes:
If only one unit is delivered, then delivery includes one piece of each item.
The unit is fixed in the box as follows:
Two separate boxes in the common package are turned such that both waveguides are heading to each other. It allows to automatically establish a link between delivered RAy3 units without unpacking them from the box. See Quick Guide, step 4 or Chapter 3, Step-by-step Guide.

RAy3-17, RAy3-24 – the same HW for Lower (L) and Upper (U) unit. L/U is used, but indicates only factory defaults for TX/RX frequencies and other parameters which needs to be different for each side of the link. All these parameters can be changed in the management (including changing L to U and vice versa).
All other RAy3 – different HW for Lower (L) and Upper (U) unit.
Selecting the pair of Lower (L) and Upper (U) units for a link allows the link to be established without any initial manual settings – just by powering up both units at factory defaults (see Quick guide or Chapter 3, Step-by-step Guide).
RAy units allow to pay only for purchased transmission capacity (pay as-you-grow concept). Activation keys could be purchased together with the unit or later at . Each key is generated for specific S/N of the unit and the purchased capacity. Once installed, it unlocks all combinations of channels and modulations up to the purchased capacity. SW keys could be erased or upgraded. See E-shopSection 126.96.36.199, “SW feature keys” for more details.
For allowed combinations of channel width and modulation for transmitting channel see Capacity SW keys table. The Capacity limit applies for transmitted data on the unit where the key is installed. SW keys for capacity could be different for each side of the link – for example if the link is expected to be configured for asymmetrical capacity.
