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).

RAy3 – Microwave link

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]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

  • 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 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.

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 antennas from different producers are available.

  

Waveguide pivot and flange

Fig. 1.2: Waveguide pivot and flange


[Important]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]Note

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.

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” .

1.2.3. Grounding screw

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]Note

Grounding screw function is to ensure proper grounding of the RAy unit (by a grounding cable), not for mechanical fixing of the unit.

1.2.4. Pressure equalization

Pressure equalization screw

Fig. 1.5: Pressure equalization screw


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]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.

Slots ETH1+POE, ETH2

Fig. 1.6: Slots ETH1+POE, ETH2


 

SlotFunction
ETH1+POEGigabit metallic Ethernet + Power over Ethernet (PoE) port
 This port is capable of powering the unit with any 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).
ETH2Slot 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.
[Note]Note

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”.

[Important]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)

RJ45 Ethernet connector

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-RAy3), 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-CAT7.

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, both polarities are supported. For RAy unit booting the minimum required 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/RJ45).

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)

SFP slot

Fig. 1.8: SFP slot


„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. RACOM offers all mentioned types of SFP modules, tested to be RAy compatible as a standard accessory.

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.

[Note]Note

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 with power consumption up to 1.25 W, but RACOM cannot guarantee their complete compatibility with RAy units.

[Important]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)

Power supply connector

Fig. 1.9: Power supply connector


DC-RJ45 adapter

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/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 min 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)

Supported voltage range is 20 to 60 V, both polarities are supported. The minimum required voltage for RAy unit booting is 21 V (to prevent booting with discharged 24 V battery). 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”.

Power via DC-RJ45 adapter

Fig. 1.11: Power via DC-RJ45 adapter


[Note]Note

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.

SFP possibilities when direct DC power is used

Fig. 1.12: SFP possibilities when direct DC power is used


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)”.

1.4. Service interfaces

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.

USB connector

Fig. 1.14: USB connector


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”).

[Note]Note

Only RACOM recommended adapters are supported. See USB adapters on RAy Accessories web site.

1.4.2. Service WiFi – optional (using USB „S“)

USB WiFi adapter

Fig. 1.15: USB WiFi adapter


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”).

1.4.3. Service Ethernet – optional (using USB „S“)

Ethernet adapter

Fig. 1.16: Ethernet adapter


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 (ordering code OTH-USB/ETH-XA) 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”).

1.4.4. RSS voltage contacts ( S )

RSS voltage contacts

Fig. 1.17: RSS voltage contacts


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.

1.4.5. HW button ( S )

Service interfaces  

Fig. 1.18: Service interfaces
 


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]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:

Production label example

Fig. 1.20: Production label example


[Important]Important

The processor included in the unit variant S and X (identified by the item ‘Code’ on production 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.

[Note]Note

A link should consist from a pair of “-L” and “-U” units (L and U are always a last letter in Code printed on production label of each unit), but it is not mandatory (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 after factory defaults (to simplify initial setting of the unit).

1.6.3. Packaging

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:

Andrew (Class 2 or 3 or 4) or traditional Arkivator antennas or antennas from other suppliers can also be used, but they require an antenna mounting kit. Flexible waveguide is a general-purpose option for any antenna usage. Contact us for available types and details.

1.6.5. Supplied accessories

Antennas and other accessories are necessary for RAy units to allow a proper functionality of the whole microwave link.

RACOM always tries to ship all ordered accessories together with RAy units and antennas. Accessories are mostly small items, so typical RACOM packaging is that all accessories are shipped on the same palette with other material (within one additional RAy box).

1.7. Ordering codes

All RAy3 models mentioned in this manual have their unique ordering codes. Available are also capacity keys, feature activation keys and accessories necessary to reach expected functionality of the link. All ordering codes are discussed in detail in this chapter and at RACOM web, and are available for purchase at RACOM E-shop.

[Note]Note

Ask your supplier to ensure completeness of your product delivery for the individual link situation, applicable spectrum regulations, local safety and security requirements, type of power sourcing, grounding, etc.

[Important]Important

RACOM does not have any responsibility for improper use of any offered device. It is customers full responsibility to check technical parameters of all ordered items and to use and configure them in accordance with their purpose. It is also customers full responsibility to respect all requirements applicable at the site of installation.

1.7.1.  RAy units

RAy ordering codes begin with a string printed on Production label (9-11 characters long, lasting by „-L“ or „-U“). It defines HW parameters and factory settings, which cannot be changed later on (like working frequency, encryption HW acceleration, factory defaults and limitations built in to units in the factory like limitation of Tx power or prevention to use any form of encryption). Rest of the ordering code defines functionalities and options which could be added, erased or changed by a user later on (like SW feature key for initial capacity or an optional DC power adapter).

Ordering Code structure:

 Trade name + Gen.RAy3
 BandFrequency band in GHz
Possible values: 17, 24
 Var.Designation of product variant. More variants can be used within one unit, i.e. more letters can be on this position. These variants are fixed in unit HW and cannot be changed later on.
Possible values:
  • none – (position not used) – means same as X

  • E – no encryption HW installed

  • N – no encryption HW installed, encryption will never be possible (neither HW nor SW)

  • X – encryption HW installed – see export restriction below, MTU 10240 Bytes

  • S – encryption HW installed – see export restriction below, MTU 2048 Bytes (manufactured only until 3/2019)

  • R – reduced RF output power -30 to -15 dBm (always in combination with E, N, X or S)

 FRQLower / Upper frequency
Possible values:
  • L – unit transmits on lower part of the band

  • U – unit transmits on upper part of the band

[Note]Note

 CodeDetailed HW identification of the unit printed on Production label on the housing.
[Note]Note

SW keys and Optional accessories are not HW dependent and can be installed or de-installed later on, so they are not printed on Production label.

[Important]Important

The processor included in the unit variant S and X 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.

[Note]Note

The proper pair of Lower (L) and Upper (U) units should be selected when ordering the microwave 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 (see Quick Guide). The difference between L and U code is only in default factory settings, which are different for each side of the link.

1.7.2. SW keys for capacity

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 RACOM E-shop. 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 Configuration / Feature keys for more details.

For allowed combinations of channel width and modulation for transmitting channel see Capacity SW keys table. The Capacity feature key limit applies for transmitted data on the unit where the key is installed. For asymmetrical capacity keys could be different for each side of the link.

Several types of SW feature key are available for RAy units:

  • Bundled capacity (ordered together with RAy units – see previous chapter)

  • Separately purchased capacity feature keys (see below)

  • Upgrade capacity feature keys (see below)

[Note]Note

RACOM is able to generate customer specific Capacity feature keys on special request.

1.7.3. SW keys for features activation

RAy units allow to pay only for purchased features (pay as-you-grow concept). Activation keys could be purchased together with the unit or later at RACOM E-shop. Each key is generated for specific S/N of the unit and the purchased feature (or a set of features). Once installed, a specific feature or function of the unit is allowed. Feature keys could be erased or upgraded. See Configuration / Feature keys for more details.

Available feature activation keys are listed in following table:
