A
n InfraRed (IR) link allows wireless connection between two distant sites. For that, two identical transceivers, each installed on one site and aligned one facing each other, provide point to point connectivity. This configuration makes possible the data transfer from one terminal to the other through the air over an optical wavelength carrier, the IR.
The installation of such a link is implemented at 4 stages: Site survey Installation of the infrastructure Mounting of the equipment Aiming procedure The term “TereScope” will be used in this Installation Manual as a general name for the series of the equipment intended for telephony.

Site Survey The first step before every installation is to physically inspect the sites to be linked. This in order to make sure that the connection is feasible, to detect potential obstacles or difficulties and to decide on the exact location and mounting points of the transceivers
Line of Sight It is imperative that the two mounting sites are within a clear sight of each other when linking two distant buildings. Pay attention to :
Growing vegetation and increasing foliage during spring Building sites (cranes movements, ...) Chimneys (drained away smokes could block the beam from time to time).
Orientation Direct sunlight could overload the airlink receiver and generate its saturation. It is preferable to install the link indoors or on the roof against the wall (to be used as shielding from sunlight). Note
In case this is not possible the surrounding buildings could shield the transceiver from direct sunlight. Otherwise outages lasting several minutes (depending on the time of the year and the angle of the sun) could occur. The system will fully recover once the sun is out of the receiver field of view.
6
Optical Access Inc. - Installation Manual
Location The mounting of the transceiver must be extremely rigid (preventing the installation from twists of 1 mrad). The key to the required rigidity is to attach the mounting accessories on strong mounting points such as: Stiff building structures Concrete or reinforced concrete surfaces (1) In case such situations could not be bypassed, special mounting accessories and techniques must be designed and considered (see section Special Installation Techniques)
Prefer Concrete Parapet Structural wall or column
Avoid Old constructions Soft material (asphalt, etc.) Non-uniform surfaces Wooden and metal structures
Pay attention to Coloured windows Double glazing The proximity of powerful radio antennas
For reasons of convenience, it is always preferable to install the units indoors in so much as all the required conditions previously described are satisfied and the customer/building owner allows it. However, when windows intervene to the beam path, the attenuating factor of the glass must be considered regarding the distance and the required fade margin. CONSULT FACTORY IN CASE OF DOUBT !

Infrastructure The only infrastructure required for operating the transceiver and linking the sites is Power and Data cables connection to the peripheral networking equipment. This must be ready prior to the link installation. AT OUTDOOR INSTALLATIONS, TAKE CARE TO USE SHIELDED AND WEATHERPROOF MATERIALS (CABLES, INLETS, CONNECTORS) COMPLIANT TO THE SAFETY STANDARD IN FORCE.
Power Source
Two following models are available : a) High Voltage Power Supply 85 – 260 Vac 50 / 60 Hz b) Low Voltage Power Supply 20 – 65 Vdc (for 4E1 or 4T1: 30-65 Vdc ) Max Power : 7Watt for E1/T1 10Watt for 4E1/4T1 Rating : High voltage units 25 - 120 mA Low voltage units 110 – 500 mA
Cabling
Standard 3 conductor power cord is required, 1mm diameter min.
An appropriate power ring cable termination must be set on each wire.
Data Cabling Type
For connecting the Transceiver to the peripheral equipment a 2 pairs STP cable is required (one pair for the transmission and the other for the reception) for the E1 or T1 twisted pair connection. For E1 coax connection two coaxial 75 Ohm cables are required. 8
Optical Access Inc. - Installation Manual
Connectors
The cable should be terminated with an RJ-48 connector for the twisted pair and with a BNC connector for the coaxial cables on the Transceiver end.

Bench Test It is always easier and more convenient to locate a failure and solve a problem in a lab on a bench than on a roof under bad conditions. It is then strongly recommended, as the circumstances allow it, to perform a bench test with all the modules prior to the installation in order to check the equipment compatibility and to validate the configuration.
Compatibility Peripheral Equipment Check the operation of the peripheral equipment connecting them through cables (see Configuration 1 below). Interfaces Check the specifications compatibility (type, standard compliance) between the TereScope and the peripheral equipment interfaces.
Testing Equipment Choose an appropriate BER (Bit Error Rate) tester for checking the physical link quality. A portable one is preferred for convenient use in the field.
Setup Mode Select Dip-switch Set all the switches on the position OFF for normal operation. Dip-switch Setup Choose: - Termination - Receive Sensitivity - Line Coding

Test configurations Before Airlink test arrange the transceivers on the table as follows and as shown in the picture: • Place two receivers on the table one opposite another at a distance of approximately 0.5 m. •
Put a divider between two channels. Use a cardboard or a wooden divider (not transparent and not a thin paper sheet). The divider is used to prevent interference between two channels as the transceivers are too close to each other.
•
Align the transceivers so that the readout on the display (Optical Power) of both transceivers is in the 50-600 range. BER test

Special InstallationTechniques This section describes two frequently encountered installation types. 1. Mounting on the floor 17
Optical Access Inc. - Installation Manual
In some cases the only place where the installation is acceptable, possible or authorized is on the floor (for example on a roof without any parapet or if the parapet is metallic, ...). In such situations drilling holes on the floor is out of the question. The principle consists in fixing in a very stable way a tower standing on the floor. The transceiver will be attached on the top of the tower. Two techniques using a small concrete block are suggested for stabilizing the tower on the floor. a.
The concrete slab is directly poured on the basis of the tower
b.
Four bolts are inserted in the concrete slab placed on the floor. The tower mount is fixed on the slab with the inserted bolts using nuts. Transceiver
JMP
Tower Mount
Concrete Slab Floor
TAKE CARE TO REMOVE ANY INTERVENING SOFT MATERIAL, SUCH AS ASPHALT, BETWEEN THE SLAB/TOWER BASIS AND THE FLOOR. ONCE THE INSTALLATION IS COMPLETED RESTORE THE ROOF WATER-TIGHTNESS WITH A SEALING MATERIAL AROUND THE SLAB. 2. Mounting on a fragile/crumbly wall
On sites on which the installation on fragile (pre-fab) or crumbly (old building) walls is unavoidable, the best way to strongly fix the JMB is to use a metallic clamping plate on the other side of the wall as sketched below. In this technique a large section of the wall is clasped providing higher rigidity and stability.

Attachment of the Transceiver After securely attaching JMP to the mounting surface choose one of the three possible directions for installation of the Alignment Kit (Standard A, B or C) depending on the location of the transceiver at the opposite side. Mount the aiming anchor (I) in accordance with the chosen direction.

Aiming Procedure Point to point connections require the orientation face to face of both “transceiving” ends of the link. Concerning wireless optical links this should be done as accurate as possible for positioning the beam symmetrically all around the remote receiver. CONNECT THE TRANSCEIVERS TO THE ELECTRICAL POWER AND CHECK THAT THE DIP-SWITCH IS ON THE NORMAL ( 3,4 – UP ) POSITION ON BOTH SITES . This procedure is implemented in two stages:
Rough Alignment This stage is intended to point, looking through the telescope, the transceiver at the opposite site and to get a first readout on the digital display. Make sure that both axes (horizontal and vertical) can turn freely. Loosen bolt F1 at least two turns and G1 aiming axis loosen slightly. Loosen bolts F2 on both sides of the transceiver. The transceiver should be aimed with the help of two axes in the direction of the transceiver at the opposite side so as to place the telescope cross in the area of the transceiver at the opposite side. Tighten firmly 4 Bolts C and D in such a way that the aiming anchor (I) will be between the screws A and B.
♦ THIS STAGE REQUIRES ONE PERSON ON EACH SITE. ♦ EACH OF THEM MUST HAVE A COMMUNICATION DEVICE (I.E., A WALKIE TALKIE, A CELLULAR PHONE). The target at this stage is to aim only the local transmitter, using the Fine Tuning Device (the 4 Fine Aiming Screws), so that the remote receiver will be situated at the middle of the beam cross section at the short distance.
20
Optical Access Inc. - Installation Manual
Fine Positioning In transmitting technology , the fine positioning procedure is very important : F1
A G1
B -Use Vertical Fine Aiming Screws A to move the transceivers vertically and Horizontal Fine Aiming Screws B to move the transceivers horizontally. -Aim the cross of the telescope in the direction of the transceiver at the opposite side using screws A and B till you get a high digital readout (100-300 depending on the installation distance) on the display on the rear panel. (In case it is difficult to get high readout by aiming with telescope, the same result can be achieved by applying the same method without telescope). -Repeat the above procedure at the opposite side. Scan horizontally and vertically the field at the opposite site using successively the Horizontal Fine Aiming Screws and the Vertical Fine Aiming Screws. The choice of the displacement direction will be dictated by the digital readout level continuously reported to you by the assistant on the opposite site. Fix the position for the maximum value and tighten firmly the four screws (2xF2 and F1,G1). Procedure:

To determine the horizontal beam edges H1 and H2, move slowly left and right the local transceiver until the digital readout on the opposite unit becomes 20-50 depending on the distance. Locate these two points relating to reference points on the opposite site looking through the telescope. Rotate the local transceiver - at the middle of these two reference points. V1

Once the position is reached, tighten firmly the 4 Fine Locking Screws (F2,F1, G1). Repeat this procedure inverting the role with the assistant on the opposite site (i.e. he will move the remote transceiver and you will report to him the digital readout on the local one). At the end of the process the digital readout should be approximately the same on both units (see Appendix A page 24 for expected readings).
After finishing the alignment process it’s possible to remove the alignment kit (2 Aiming Lugs E1, E2 and Bolts C and D).

Installation Completion Link Operating Test Connect on both sites the STP Data cable or the coaxial cables coming from the peripheral equipment. The Electrical Flag indicator should switch ON as soon as the peripheral equipment is powered ON. A BER test is recommended. In case this is not possible check at least with the customer/user the performances of the whole link (see the chapter Bench Test).
Installation Log Write down all the information about the installation (including digital readout and the setup of the transceivers) in an installation log. This information could be a valuable reference for future maintenance or troubleshooting visits.
An installation form is proposed as an example in Appendix C (see page 26).
Sealing of the units Check that the cables are well engaged in the connectors, and the Fine Locking nuts well tightened. Close the rear door, and Lock the door with the Door Locking Screws located on the sides of the transceiver. (with 2.5mm Allen Tool ).

Maintenance Periodic Visits (every three months) should be planned for: Checking the display Checking the mounting Cleaning the optical aperture of the transceivers Cleaning the building windows for indoors installations. At cleaning time, the reading of the digital readout should be marked down in a service log book. Once the optical aperture is cleaned, if the reading is substantially lower than that noted at installation time, the aiming accuracy should be examined and restored if necessary. Note
Aiming accuracy should be checked looking through the telescope and comparing the present scene sighting to the one sketched in the Installation Log at installation time.
