Wireless Bridge РРС-1000 is intended for full duplex 1Gigabit communication between two
remote points. It is composed of two subscriber transceivers which are operated within line-ofsight conditions at working frequencies within mm-wave range.
Two different central frequencies are used for the duplex operation. One Radio (High)
transmits data at a frequency of upper part of the frequency range and the second one (Low)
uses a frequency from the lower part. The label on the radio indicates whether it is a Highband (HI index in the end of serial #) or Low-band one (LO index in the end of serial #).
Thus, PPC-1000 provides 1.25Gbps capacity in each way.
Each Radio is “all outdoor” unit. The only things operator to do for installation are to mount
both radios on vertical pipes, connect them to data cables and power, ground them, and point
one radio to another one.
As both Radios operates in a full duplex mode, they should be connected to an equipment,
operating in a full duplex mode.
Before the start of an installation a survey should be conducted of the proposed area of the
site(s). The survey personnel should be familiar with the details required to install the radio
system.
3.2 Equipment Checklist
The survey team may need the following equipment:
• Binoculars or spyglass
• Range-finder or GPS Navigation Device (to determine the exact link distance)
• Mobile phones or walkie-talkie radios
3.3 Line of Sight (LOS)
The mm-wave wireless link requires Line-of-Sight for proper operation. It implies that no
obstacles like trees, buildings, chimneys have to be between the station sites. Moreover, no
obstacles should be situated in the vicinity of the signal propagation line (inside the first
Fresnel region).
Because the link distances are usually within 10 km so obstructions in the path can easily be
identified using binoculars.
The planning should include an investigation into future building plans that could block the
LOS path, and other long-term incremental obstructions such as growing trees. Intermittent
but regular obstructions such as flying aircrafts at a nearby airport should also be considered.
It is required to have absolutely no obstructions in front of the antenna in so called first
Fresnel zone. The minimum required clearance from obstacles is 60% of the first Fresnel zone.
Fresnel zones are a series of concentric ellipsoid areas surrounding the straight-line path
between two antennas. The first Fresnel zone is the area containing every point of which the
distance from the transmitter to any reflection point on the area and on to the receiver is half
a wavelength longer than the path of the direct signal. The radius of the Fresnel zone is
greatest at midpoint in the signal path.
Minimum Clearance for various bands is listed below (in meters):
Path Length
(km)
Q-band
40.5-43.5
1 km 1,4 m 1,1 m 1,0 m 0,9 m
2 km 2,0 m 1,6 m 1,4 m 1,2 m
5 km 3,2 m 2,5 m 2,3 m 1,9 m
It is recommended that installation personnel read this section in its entirety prior to installing
the System. During a particular phase of installation, the user may refer directly to the
applicable subsection.
4.2 Equipment Unpacking
The radio system equipment will arrive in two to four wooden boxes depending on antenna
diameter. For small antennas it’s usually 2 boxes in the shipping —one box for the low band
radio and one box for the high band radio. It is recommended that the shipping boxes and
packing materials be retained in the event that it is necessary to return equipment.
Open the top cover of the box, and take out the antenna first (for small antennas link only).
Large antennas come in separate boxes and have to be unpacked accordingly.
The radio case with alignment mechanics and cable pack is fastened to a wooden plate within
the shipping box to prevent damage during transportation. When unpacking the radio,
remove metallic straps, and then take the radio out of the box, lifting the right side first (see
photos below).
Unscrew the shipping bolts and detach the wooden plate to fully unpack the radio case.
The paper boxes with accessories are fastened to a bottom of the shipping box. Remove their
shipping straps and take out the boxes with accessories.
Each box is accompanied by a packing list. Verify the contents of the box against the packing
list. Following are inventory lists for a typical system (30 cm antennas).

• Hose clip, 50-70 mm (item 8)
4.5 Equipment assembling
Both radios equipped with 61 long shipping bolts (see
photos from part 4.2 Equipment Unpacking).
Replace the shipping bolt placed near the “Ground” mark
with a set #15, observing the items order. The Radio
flanges should be placed between contact strips.
Connect the grounding wire to the bolt as shown on the
photo.
Replace the rest 5 shipping bolts with bolts, nuts,
washers and tightening washers (set #14).

The exact number of the bolts used for shipping purpose may differ.
60 cm antennas come in separate box. To assemble antennas, do the following:
• Set included joint scaling strip into the flange seal groove
• Remove top covers from antenna and the Radio flanges
• Match antenna and radio flanges, according to waveguide orientation
• Fix an antenna on the radio with 6 bolts, washers and tightening washers, included in
the complete set
CAUTION!
Fixing 60 cm antennas, observe waveguide orientation, paying attention that wave-guide-fed
slot orientation on antenna matches the orientation of the waveguide on radio case. Otherwise
the Bridge will not operate properly.
CAUTION!
During antenna assembling, take precautions against ingress of dirt, dust and moisture into
antenna and Radio waveguides.
4.7 Radio on-table testing after unpacking (optional)
After the unpacking and antenna assembling of the radios, you could test the radios on-table
before installing them at their principal location (mast; tower; roof of the building). This is an
optional operation but after the test you will be sure that radios works OK and there are no
malfunction because of the damage during transportation. The test includes only parameter
diagnostics. The main data communication channel will not be tested at this moment.
You will need a stand-alone notebook or desktop PC with installed LAN card to display test
results through SNMP. The following software has to be installed at this computer:
1. Moxa NE SDK Manager
2. ELVA PPC Monitor
The Moxa NE SDK Manager is third-party software which you can use in accordance with End
User License. You are provided with your copy of this software because of partnership between
ELVA-1 and Moxa.
ELVA PPC Monitor is ELVA-developed SNMP monitor apps.
Please do not distribute these software applications outside your organization without written
permission of ELVA-1.
You can download both software apps from the following location
It’s doesn’t matter the actual IP address number you choose, the only important thing is to choose
the IP address from the same subnet and differ from IP address, allocated for radios by default. It
could be someone from this range: 192.168.127.0-253. For example, 192.168.127.220.
Use the default subnet mask 255.255.255.0.
•Connect SNMP cable (item #6 from inventory) to radio one end, and to Power supply
(item #11) and RJ-45 LANcard socket of the computer other end (see photo below).
Use “straight” UTP cable extension cord, if needed.
•Switch the power supply of the radio ON and test connection between radio and your
computer with Windows PING application
(click Start – Run, then type Ping 192.168.127.254).
• Run PPC Monitor application your computer. Then click START and GET buttons.
• You have to get a reply from the transceiver, similar to the following one.
•Check Identification window, you will see detailed info about allocated frequencies and
bandwidth (these parameters are factory preset, cannot be adjusted by customer).
If you see reply which is similar to illustrated above one, your radio works OK. The detailed
explanation of PPC Monitor displayed parameters you will find below in “7. Installing and
running SNMP software” chapter.
After this optional on-table testing of the reply from transceivers you can continue with
radio mounting.
4.8 Radio mounting
The station should be fastened on a vertical
tube of 40..80 mm diameter and not less than
500 mm height.
Bending and torsion rigidity of the support leg
has to be enough to prevent angular swing of
the antenna in both the azimuth and elevation
Use the hose clip #8 to prevent the Radio from
shipping down when run the alignment of the radio.
The normal PSU output voltage is 54 VDC. The voltage in DC cable at the point of Outdoor
Cross-box end because of voltdrop should be not less than 48 VDC .
•Install a 4-pair Twisted Pair cat.5 cable from the Outdoor to Indoor Cross-box
CAUTION!
Be sure that the UTP cable length is less than 100 m
•Install fiber optics cable from indoor host equipment directly to the radio. It is
recommended not to have any cross-connection in this cable between radio and indoor
host equipment. The optics cable welding equipment will require at this step.
1. Open optical connection box at radio case using screwdriver with star bit.
2. Put one of gland (item #18) on fiber optics cable.
3. Insert cable into optical connection box at radio case and weld optical connector.
4. Insert optical connectors to relevant socket at the adapter in optical connection
box.
5. Close optical connection box using screwdriver with star bit .
4.10 Outdoor cross-end connections and Grounding
•Connect the stationary TP cable to Outdoor cross-box with Ethernet connector (to 110
type connector), special push tool may required (not included to the shipment, it’s very
common tool and can be obtained at your network administration department).
• Connect stationary DC cable to outdoor cross-box with terminal block.
• Connect TP/Power cable (#6) to Outdoor cross-box RJ45 and power connectors.
• Connect grounding cable (#7) to outdoor cross-box with terminal block. Instead of
connection to the outdoor box, it’s allowed to connect grounding cable to a nearest
grounding point at the roof, if such connection available. The grounding cable at radio
side has to be connected to earth connector, marked with the earth symbol (bolt M5,
see photo on page 12).
•Plug TP/Power cable (#6) to the Tuning panel and the TP/Power cable from Tuning
panel – to the relevant connector on radio case. Using Tuning Panel as intermediate
device between Outdoor cross-box and radio is required for alignment purpose only.
After completing of alignment procedure, the TP/Power cable from Outdoor cross-box
has to be connected to relevant connector at radio case.
WARNING!
Grounding of both Radios is a mandatory requirement
DANGER!
This product is not designed to withstand direct thunderbolt. It should be operated only under
protection of external lightning rod.
4.11 Power connection indoor
•Connect stationary DC cable to Indoor cross-box with terminal block
• Connect cable #5 to Indoor cross-box with terminal block
• Connect Power supply unit to Indoor cross-box with cable #4.
4.12 Connection to Network Equipment indoor for SNMP administration
•Connect Ethernet connection box #12 to the stationary TP cable in much the same way
as for outdoor TP connection
•Plug-in UTP cable from office LAN equipment to indoor Ethernet connection. With the
link power switched on, and installed SNMP software you can use link SNMP
administration from one of the office PC.
Precise alignment should be performed at fair weather and good visibility. For precise
alignment it’s recommended to have people at each point of the link. The two-way
communication like mobile phones or walkie-talkie radios required to coordinate their efforts.
The precise alignment is carried out after both the stations have been installed, connected to
the power supply source and tuning panel.
Precise aligning is carrying out according to AGC (Automatic Gain Control) level of the station
under alignment. To measure AGC do the following:
•Have all cables connected and power switched on, with Tuning panel #10 inserted
between cable #6 and Radio (see photo below).
ATTENTION!
Check the color of Power supply LED when using the link in transmitting/receiving mode. The
normal LED color has to be YELLOW. Green LED – no load, Red LED – overload.
•Push Tuning panel button until it shows AGC level (the value marked with A symbol).
There are 5 indications at Tunning panel:
o A = AGC
o C = Temperature at controller inside radio case
o c = General temperature inside radio case
o U = Tx voltage
o u = Rx voltage
An antenna pattern has mainlobe and at least two sidelobes (first
harmonic sidelobes). The big antennas (60 cm) could have more
sidelobes (second and third harmonics), but their intensity are very
small.
In 3D projection the mainlobe and sidelobes are like two cones, one inserted to another. Your
goal is to align both antennas for mainlobes.
How to be sure you get to mainlobe, not to sidelobes? First check the AGC voltage at Tuning
panel and compare with value, provided at Passport of the radio for your distance. These AGC
voltage values in Passport are provided for mainlobe. You need to know exact distance
between two radios of the link. Use GPS navigator or range-finder to calculate exact distance
of the link path.
For mainlobe, the AGC voltage at Tuning panel has to be closely to the value in Passport for
s
such distance. For sidelobe, the AGC voltage at Tuning panel will differ (will be higher)
compare to the value in Passport for such distance for a value of about 1 Volt.
Second, as result of the successful alignment you have three minimums of AGC voltage when
scan the line of sight horizontally (see schemas below). If you have only two minimums, it
means you missed the mainlobe.
The alignment procedure is as following:
1. Start slowly moving both
radios within a line of sight,
trying to get a first contact
of at least sidelobes.
Pay attention to AGC
voltage, and look for a
voltdrop.
Scan the line of sight
simultaneously
radios until the first c ontact
of sidelobes.
Stop movement of both radio
at this p oint, then begin
a precise alignment
by one radio only to get to
mainlobe. Then repeat for
another radio.
for two
Look for a voltdrop
of AGC voltage
•When got a voltdrop of AGC voltage, immediately stop moving of both radios (say
“STOP” to your partner, working at another radio).
•Have another radio static; very slowly scan your radio horizontally closely to the point
of first contact.
•Check how many voltdrops you will get when do scanning horizontally. If this will be 3
minimums, the central one is mainlobe. If you got only two minimums, it means you
missed the mainlobe. Try to stop the antenna horizontally at center of the virtual arc
between two AGC voltage minimums, then slowly scan the antenna vertically to find
mainlobe.

•Having the alignment completed, tighten internal nuts and external bolts of the
adjusting plate. Remove the Tuning panel, plug the cable #6 into the Radio.
•Test the quality of the data transmission via the radio-channel.

CAUTION!
The alignment can be considered as completed if the AGC voltages on both the stations agree with values for the given distance, mentioned in the Passport.
CAUTION!
AGC voltage instability or/and no expressed maximum of the received signal indicate
substantial reflections within the directional diagrams of the transceivers. In turn, this implies
existence of obstacles in the vicinity of the signal propagation line. In such a case you advised
to change the location of the radios.
Each of the PPC-100 links is shipped as SNMP enabled and could be monitored online. The
SNMP feature is optional, it does not directly affect to link ability to transmit and receive data
through main channel. Without SNMP enabled, the link will still work, likely as unmonitored
piece of cable.
To use SNMP monitoring, you have to install two software applications
1. Moxa NE SDK Manager
2. ELVA PPC Monitor
Each radios contains built-in MOXA switch IC. To manage switch IP address, you need to use
this software. The Moxa NE SDK Manager is third-party software which you can use in
accordance with End User License. You are provided with your copy of this software because of
partnership between ELVA-1 and Moxa.
ELVA PPC Monitor is ELVA-developed SNMP monitor apps.
Please do not distribute these software applications outside your organization without written
permission of ELVA-1.
6.1 Installing and running NE SDK Manager. Changing IP-address of the
transceivers
1. Install Moxa NE SDK Manager on the computer which you intended for PPC-100/STM1
SNMP administration (run Setup.exe). While NE SDK Manager is quite complicated
software you will use the only one its feature – how to change IP address of each radio
of the link from default IP address to an address which is provided to you by your
network administrator.
2. Run Moxa NE SDK Manager. Use ‘Network Enabler SDK 2 Programmer Guide1.pdf ‘ as
your reference how to work with NE SDK Manager.
3. Scroll down the reference file to page 3-5 to understand how to find a switch inside
radio case in this manager.
4. Click to Search button in main window of NE SDK Manager (most left button at
toolbar). The NE SDK Manager will find MOXA switch, which is build-in to transceiver.
6.2 Installing and running PPC Monitor. Using this application for
transceiver parameter monitoring
1. Run PPC.exe application from hard disk of the computer, intended for SNMP parameter
monitoring. The main window of PPC application will be open.
2. Enter the IP-address of the transceiver you would like to check. Next time you start the
PPC monitor, this IP address will be saved in drop-down list.
3. Enable Auto Update checkbox and click Start button.
ATTENTION!
The main mode for all components of the transceiver is automatic. All manual changing of the
transceiver parameters like power on/off, heater and fan on/off which made in PPC Monitor are
active for 30 Seconds only. After 30 sec the transceiver will return to internal automatic
microprocessor control. This is to prevent damage of the equipment.
ONP – power ON for internal power supply adapter of the radio (always ON by default). Please
mind each radio has external Power supply and internal power supply adapter. When you
disabling ONP checkbox, you make dead circuit for radio electronic adapters, but not for
external Power supply. To switch off the link completely, you need switch off external power
supply (item #11).
ATTENTION!
ONP parameter can be used for link restart. Click STOP button, disable this checkbox and click
SET button, then START button.
Checkboxes:
FAN – internal fan switch on/off (built-in fan is optional feature)
ON1 – internal heater on (standard mode)
HI1 - internal heater on (boost mode)
SW1, SW2 – reserved for future use
Compare level – special parameter for service technician only. Please do not change this
parameter.
Community name – “public” by default.
Interval – indicates how often the link parameters will be renewed at PPC monitor in
milliseconds.
GET button – to get link parameters displayed in PPC Monitor window
SET button – to make active changes which made for power on/off, heater and fan on/off.
START – starts PPC Monitor application.
STOP - stops PPC Monitor application
Auto Update – enable this checkbox for automatic update of link parameters in PPC monitor
window.
EXIT – exit from PPC Monitor application
Temperature box parameters:
Temperature Crystal – microcontroller chip temperature
Temperature sensor 1 – temperature inside radio case
Temperature sensor 2/3/4 – reserved for future use (=0.00)
Voltage box parameters:
U receiver – receiver heterodyne voltage (service parameter to be send to service)
U transmitter - voltage (service parameter to be send to service)
AGS voltage – Voltage of AGC parameter
U +32/27, U +9/12, U +5 – voltages for internal power supply adaptor. Check them to be sure
that displayed values are close to ideal one. For doubled numbers like 9/12 check the value to
be close to one of the pair.
Source current – the total value of the current consumed from external power supply.
Log to file (.txt) – you can write displayed parameters to the file. Enter file name with .txt
extention. This data could be further exported to Microsoft Excel.
ATTENTION!
To see transceiver parameters by the Internet, you have to use for transceivers real Internet
static IP-addresses, obtained from ISP (Internet Service Provider). Please carefully discuss this
possibility with your network administrator as the link will be open to hackers in this case.
7 Maintenance and Troubleshooting
The PPC-100/STM1 Bridge has been designed such that it requires no user configuration.
The PPC-100/STM1 Bridge itself does not require periodic maintenance. However, each end of
the link should be periodically inspected for visible damage or excessive accumulation of dirt.
In a case of communication disturbance, it is necessary:
1. Make sure of integrity of the stations and the antenna, of that the cable joints are reliable
and no strange, unauthorized objects are on the antennas. Remove dust, snow from antennas
if necessary.
2. Check the signal propagation line visually and make sure that no obstacles like buildings,
cranes, electric lines, trees have appeared on it or in its vicinity. In a case of necessity remove
the obstacle or change the radio position.
3. Make sure of that the radio is properly fed with the power supply:
Measure the voltage on Outdoor cross-box terminal block while Radio is on. The power supply
voltage should be within the 38 to 60 V range. If it is not so, clear the fault of the power
supply source or cable.
4. Make sure of that the data arrive properly to Radio via the twisted-pair/optics cable.
5. Check the AGC voltage. The AGC voltage should correspond to a value, given in the
Passport for actual distance. If it is not so, discover and remove the cause. Possible causes:
•Precipitation along the signal propagation line. Wait until the good weather and repeat
the measurements.
•Obstacles on the signal propagation line. Remove them or change the position of the
radio.
• Alignment disturbance. Re-align the stations.
• Response transmitter failure.
If nevertheless the Radio does not operate properly, measure and write down AGC voltage,
make PPC monitor screenshot or write the parameters to the file, then contact to Service
Center.
