Prior to installation, it is best to be familiar with the front panel of your particularmodel. Sections 2.3.2 through 2.3.5 briefly describe the front panel access and lights from left toright.Figure 2-1: Front Panel, 2.4 GHz & 5.8 GHz 1xE1Figure 2-2: Front Panel, 2.4 GHz & 5.8 GHz 2xE1Figure 2-3: Front Panel, 2.4 GHz & 5.8 GHz GHz 4xE1

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 2-12 SECTION 2: PRODUCT DESCRIPTION2.3.2 Test Points / Power IndicatorON This is an LED indication. When lit GREEN, the LYNX.sc is powered.The LYNX.sc radio products do not have an on/off switch.GND This is a test point referenced to chassis ground. This is used in conjunction with thenext two test points to measure voltages related to radio performance.RSL This is a test point which relates to the Received Signal Level (RSL). A voltage can bemeasured with a voltmeter (using the GND test point for reference) which correspondsto the actual power level of the incoming received signal. While the DISPLAY FAREND button is pressed, this RSL voltage corresponds to the RSL of the far-end radio.These measurements are used during installation, maintenance and troubleshooting.LOCAL TXPWR This is a test point which corresponds to the output transmit power of the radio. Avoltage can be measured with a voltmeter (using the GND test point for reference)which corresponds to the actual power level of the outgoing signal. This measurementis used during installation, maintenance and troubleshooting.This voltage only applies to the near-end and does not allow measurement ofthe far-end output transmit power, even when the DISPLAY FAR END buttonis pressed.There is a receptacle on the front panel to the right of the LOCAL TX PWR test pointwhich is an installation adjustment allowing the output transmit power to be increasedor decreased within the radio's specified limits. Using a small screwdriver, thisadjustment is used to set the output power of the transmitter, in accordance to thepath planning.The LYNX.sc systems requires professional installation. Transmitted outputpower limits may apply when using this radio. Consult FCC, IC, ETSI WesternMultiplex or other regulatory authorities for limits which may apply. SeeSection 3.13.1 for details on setting output power.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 2: PRODUCT DESCRIPTION PAGE 2-132.3.3 Alarm and Status IndicatorsDATALOSS When lit RED, this is an alarm condition indicating that the LYNX.sc radio is notreceiving E1 input data on the corresponding data input channel. This alarm functioncan be disabled by rear panel DIP switch setting (see Section 2.4.4). Under data losscondition, the local transmitter injects AIS (Alarm Indication Signal).BER This is the Bit Error Rate (BER) alarm. When lit RED, this alarm condition indicatesthat the received signal bit error rate is above the error threshold of 1 x 10-6. This alarmcondition typically indicates a path problem or a problem with the far-end radio andusually is not a problem with the near- end radio.RX SYNC When lit RED, this is an alarm condition indicating that the intended received signal isnot being received. This alarm may indicate problems related to the path,connections, or the near-end or far-end radio hardware. When the RX SYNC alarm isactive, AIS (Alarm Indication Signal) is injected into the E1 line transmit output dataport.AIS OUT When lit RED, this is a status condition indicating that the radio receiver istransmitting AIS (Alarm Indication Signal) on the E1 line transmit output data port, dueto loss of received signal. This typically indicates a path or connection problem or anear-end or far-end radio hardware problem. This alarm function can be disabled byrear panel DIP switch setting (see Section 3.12.5).FAN When lit RED, this is an alarm condition indicating a failure with one or both of theinternal cooling fans. The radio is designed to operate within specification when onlyone fan is operating. The two fans are provided for redundancy only.RADIOFAIL When lit RED, this is an alarm condition indicating a major failure with the near-endradio hardware. It can also indicate improper connections to the CEPT-1 input port.FAR END When lit RED, this is an alarm condition indicating that there are alarm or statusconditions present on the far-end radio. Press and hold the "Display Far End" buttonon the near-end radios to indicate the alarm conditions for the far-end radio terminal.Monitoring the far-end alarms can be helpful for radio installation and routinemaintenance.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 2-14 SECTION 2: PRODUCT DESCRIPTION2.3.4 ControlsLoopback is a test method used which transmits either an internal or externalE1 test signal and loops this E1 signal back at the far-end radio (re-transmitsthe signal back to the near end). The near end then receives the signal. Thisis very useful for testing because the test signal can be monitored at thenear-end and the quality of the entire link can be measured using a Bit ErrorRate (BER) test, or internal test features, without anyone going to the far-endradio location.ERROR When lit RED, this indicates that a bit error occurred while in loopback mode. If youare not using a BER test set, this LED may be observed to determine if there are anybit errors during loopback, for example during an overnight test.ENABLE This is a push-button switch that executes the loopback mode for the correspondingchannel. Loopback is initiated by pressing and holding this switch for approximately 3seconds. Once in loopback mode, the LED which is embedded in the switch isilluminated YELLOW to indicate that Loopback is ON. The LED on the near-end radioflashes while the far-end is solid. Loopback is disabled by pushing and releasing theENABLE button at either the near-end or far-end radio.Enabling loopback will interrupt traffic. This is an out-of-service test.CH SEL This is a push-button switch provided only one the 4xE1 version that selects thechannel for loopback mode. The channel is determined by the number of times theswitch is pressed. Press (hold for 2 seconds and release) for channel 1, press againfor channel 2, press again for channel 3 and press again for channel 4. Loopback isinitiated using the ENABLE switch; the LED in the CH SEL button flashes in a groupsequence to identify which channel is selected for loopback.DISPLAYFAR END This push-button provides the capability to determine alarms and status of the far-endradio. When pressed and held, the alarm and status LEDs and the RSL test pointcorrespond to the far-end radio’s status and RSL value. This can be used forinstallation, maintenance and troubleshooting. When the LED on this switch isflashing, no far-end information is available. This typically indicates that there is nolink between near-end and far-end radios.

This is a facility for "telephone" styleservice from one radio to another. A standard electronic telephone [one with a handset and DTMF(push-button tone) dialing] plugs into this connector. The user can dial the orderwire address of thefar-end radio (or any radio in the LYNX.sc network) to establish telephone communication betweensites. This communication does not interrupt or interfere with the other radio communications. Theradio link must be operational to use this facility. The orderwire feature can be very useful forinstallation, maintenance and troubleshooting.-Touch-tone Telephone* (for communication with far-end)*Telephone connection specifications:REN (Ringer Equivalency Number) 1.0 BDTMF tones within ±1.5% of nominal freq.Ringing Voltage 48 VDC, typical(Ringing voltage is adequate for modern solid state ringers,NOT for the older mechanical type ringers)

Prior toinstallation, you should familiarize yourself with the rear panel.Figure 2-4: Rear Panel, 1xE1Figure 2-5: Rear Panel, 2xE1Figure 2-6: Rear Panel, 4xE1

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 2: PRODUCT DESCRIPTION PAGE 2-172.4.1 RF ConnectionThe RF port of the LYNX.sc radio is an N-type female connector that is an integral part of the filterassembly. The filter assembly occupies nearly the entire top half of the rear panel. The N-Typeconnector is used to connect the antenna, typically using coaxial transmission line. In some cases,waveguide may be used as the primary transmission line, in which case a waveguide-to-N adapteris required.For the LYNX.sc, 1/2" or 5/8” coaxial cable (LDF4-50 or LDF4.5-50) is recommended. Coaxial cable that is 7/8” or larger canexhibit moding at 5.8 GHz and is not recommended for 5.8 GHzradios. For waveguide transmission line at 5.8 GHz, EW-52waveguide is recommended. EW-63 will also work, but mayexhibit more loss.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 2-18 SECTION 2: PRODUCT DESCRIPTION2.4.2 DATA ConnectionsThe connection for the CEPT-1 (E1) interface is shown in Figure 2-7 as J1 through J4 (additionallyJ5 through J8 on the 4xE1 model). These connections carry the E1 signals in and out of the radio.Multiple capacity (2xE1 and 4xE1) provide extra sets of input and output ports to connect each E1signal.The BNC data ports accept bipolar signals with the shield normally left open (floating) in order toeliminate ground loop problems. If desired, the BNC shield on the data ports may be grounded usingswitch settings on SW2.For balanced E1 input, use a 120 ohm balun and BNC cables toprovide a RJ45 4-wire connection. SW2 has no effect when usingthe typical balun.Figure 2-7: CEPT-1 Interface Grounding Switch

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 2: PRODUCT DESCRIPTION PAGE 2-192.4.3 Auxiliary Data ConnectionsThere are 5 auxiliary data connections for LYNX.sc as shown in Figure 2-4 through Figure 2-6.VF This connector is used to link two LYNX.sc radios at a repeater site for Orderwireoperation. This would allow orderwire "telephone" calls to and from any point in theLYNX.sc network.The LYNX.sc orderwire circuit can also be connected to other existingorderwire networks. See Section 3.14.1 for details.ALARM This connector is used for monitoring alarms electrically. The alarm connections areessentially the same as described for the front panel, however instead of LEDoperation, alarm status is provided electrically by means of TTL and Form C relayconnections. The TTL and Form C relays can be connected to other transmissionequipment for monitoring alarm status locally or remotely.DIAG-NOSTICS This is a serial interface port (RS-232 or RS-422, ≤9600 baud) to the LYNX.sc radio.This port provides maintenance information about the LYNX.sc radio(s) to a connectedcomputer or terminal. This port is typically used for maintenance and troubleshootingor connection to network management systems.AUXDATA This is a serial interface port (RS-232 or RS-422, ≤9600 baud) which allows the userto connect auxiliary serial data from one point in the radio network to another. Thisfacility can also be used for bridging the DIAGNOSTICS port for remote alarm andstatus monitoring (TBOS network management) or for connecting other equipment'sserial alarm information. It can alternatively be used for separate data connection forLANs or other serial devices.PROTECT This is a port used to connect the LYNX.sc radio to an additional unit for MonitoredHot Standby (MHS) or Space Diversity (SD) configuration. The MHS and SD units canbe configured to provide protection to the LYNX.sc radio by means of a "back-up"radio which would switch-in should there be problems with the primary radio or theradio path.The protect feature is not available at the time of the printingof this manual

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 2-20 SECTION 2: PRODUCT DESCRIPTION2.4.4 SwitchesThere are two sets of 8-segment DIP switches (SW1 & SW3) and two rotary switches (AddressTENS and ONES), as shown in Figures 2-4 through 2-6 on the rear panel of the LYNX.sc radio.These switches provide user configuration of several radio parameters. A brief explanation for eachfunction follows.Refer to the switch setting detail in Appendix B for yourparticular model.SW1InputAlarmDisableThese switch segments allow the user to “turn off” the DATA LOSS alarm for any inputchannel. This can be helpful if the data channel is not in use or while performingmaintenance to temporarily turn off the alarm indication. Even when this alarm isdisabled, the LYNX.sc radio will inject AIS into the transmitted data stream whenthere is a data loss condition. (see Section 3.12.4)LoopbackMode This switch segment allows the user to select either the internal or an external testsignal while in loopback mode. (see Section 3.12.2)ErrorUnlatch This switch segment selects an optional mode for the ERROR LED to flash for eacherror occurrence (instead of latching on). This can be useful for short durationloopback testing when the operator is located at the terminal site and watching forerrors. (see Section 3.13.3)AISDisable This switch segment allows the user to select whether or not an AIS signal will beautomatically injected into the received E1 data stream at BER ≥ 1 x 10-3. This can beuseful for measuring threshold or when a E1 channel is not in use. The AIS will beinjected into the received E1 data stream if the radio loses sync (RX SYNC alarmactive), even if the AIS disable function has been selected. (see Section 3.12.5)Diag-nosticProtocolThis switch segment is default set to Telemetry Bit Oriented Serial (TBOS) mode onthe diagnostics port. This is a non-proprietary network management protocol which iscommon to some radio networks. The other selection is for factory use only. (seeSection 3.14.3)EnableAuxDataThis switch segment allows the AUX DATA port to be optionally used as a clearservice channel for RS-232 or RS-444 (≤ 9600 baud) user data. The radio normally“bridges” the AUX DATA port to the DIAGNOSTICS PORT for TBOS radio networkmanagement. (see Section 3.14.4)

The shield is normally “floating” to eliminateground loop problems. (see Section 3.11)SW3Spread-ing Code This set of switch segments allow the user to select the spreading code for the spreadspectrum signal. Both ends of a radio system must be set to the same code. Usersmay wish to change codes for radios that are nearby other similar radios to aid ininterference rejection. (see Section 3.12.3)ChannelSelection This set of switch segments programs the radio to match the specific RF channelcorresponding to the RF filter set which has been installed. (see Section 3.12.1)Address There are two rotary switches which determine the radio's address (01 to 99). Thisaddress is used for Orderwire signaling and for the DIAGNOSTICS port TBOSaddress.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-33.3 Before Installation Task ListThere are several tasks that should be accomplished prior to installing the LYNX.sc radio system.This section briefly describes the following:- Site selection- Line-of-Sight and Path Clearance determination- Anticipated RSL calculation- Fade margin calculation- Availability calculation- Frequency plan determination- Power supply planning- Antenna (and accessories) purchaseOnly directional antennas should be used with LYNX.sc spreadspectrum radios. These can be grid or solid parabolic antennas(minimum 2 foot - .6 meter). Flat panel antennas are alsoacceptable if the beam width is kept to a minimum.3.3.1 Site Selection RequirementsThe radio site must have:- access to the appropriate power- close proximity to the telephone or computer system you wish to interconnect- line-of-sight to the other radio location with adequate clearance- location for mounting the antenna

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-4 SECTION 3: INSTALLATION & ADJUSTMENTS3.3.2 Line-of-Sight and Path Clearance GuidelinesThe LYNX.sc radios will not operate properly unless they have line-of-sight between theircorresponding antennas. The LYNX.sc radio transmission will not pass through trees or otherobstacles. Factors to consider include:- Earth curvature- Future growth of trees- Height of buildingsIn addition to the line-of-sight requirement, a well-engineered path will also have additional pathclearance to allow for signal loss due to partial obstructions, atmospheric ducting and groundreflections. To maximize radio reception, 0.6 times the first Fresnel zone should be calculated andthis distance added to the path clearance (in addition to trees or buildings).

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-53.3.3 RSL Calculation and Link BudgetThe received signal level (RSL) can be estimated using the following formula:RSL (dBm) = Pout - FL1+ G1 + G2 - FL2 - Lpwhere: Pout is the transmitter output power (in dBm)FL1 is the feeder loss of the transmit side (in dB)G1 is the gain of the transmit antenna (in dB)G2 is the gain of the receive antenna (in dB)FL2 is the feeder loss of the receive side (in dB)Lp is the Path loss, defined by:Lp (dB) = 96.6 + 20 log10F + 20 log10Dwhere: F = Frequency in GHz (2.4 or 5.8)D = Distance of path in milesThis link budget is very important for determining any potential problems during installation. If youhave calculated the expected RSL, you can see if it has been achieved during installation, andtroubleshoot if necessary.In the USA, 5.8 GHz models of the LYNX.sc may be installedwith any size directional antennas and operated at full power.The 2.4 GHz model may require power reduction where: Pout -FL1+ G1 is replaced by 30 - [(G1 - 6)/ 3] + FL1In some countries effective isotropic radiated power (EIRP)limits apply, such as +6 dBW (+36 dBm) in Canada. Outputpower may need to be reduced, and the above path planningequation changed such that: EIRP (dBm) = Pout + G1 - FL1

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-6 SECTION 3: INSTALLATION & ADJUSTMENTS3.3.4 Fade Margin CalculationThe fade margin is the difference between the actual received signal and the radio’s threshold. Usingthe formula provided in Section 3.3.3, the anticipated RSL can be calculated. Compare this RSL tothe specified threshold of the LYNX.sc radio, which is shown in Section 2.2, and calculate the fademargin as the difference between the two signal levels.Dispersive fade margin is another factor that many microwave path engineers may use to plan theirlink budget. For the LYNX.sc radio, the dispersive fade margin is in excess of 55 dB and thereforeis not a determining factor in path planning. This excellent dispersive fade margin performance isimportant because the spread spectrum RF signal has considerably wide bandwidth.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-73.3.5 Availability CalculationAvailability of the microwave path is a measure of the percent of the time that the link will operatewithout producing an excessive BER due to multipath fading. In the absence of direct interference,availability is affected by the following:- Path length- Fade margin- Frequency (2.4 GHz or 5.8 GHz in the case of the LYNX.sc radios)- Terrain (smooth, average, mountainous)- Climate (dry, temperate, hot/humid)Depending on the type of traffic carried over the link, the system designer may wish to design for aspecific availability. For example, if the data or voice traffic that is carried by the radio is critical thenit may be designed for a very high availability (e.g. 99.999% or 5.3 minutes of outage per year). Toimprove availability, for example, the fade margin can be increased by making the path shorter, orby using higher gain antennas in conjunction with lower loss feeders (by using high qualitytransmission line or shortening feed length).

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-8 SECTION 3: INSTALLATION & ADJUSTMENTS3.3.6 Frequency Plan DeterminationWhen configuring radios in a hub or repeater configuration, careful engineering of the LYNX.sc radiofrequency plans and antenna locations should be performed in order to minimize potentialinterference between the nearby radios. As a rule of thumb, do not place identical frequency planradios (e.g. two “A” channel radios) at the same site. In most cases, it is desirable to use a differentfrequency plan (e.g. A versus B). However, with careful engineering, placing more than one radio ofthe same frequency channel plan at the same site can be accomplished. In fact, the LYNX.scfrequency plan is designed to allow complex hub configurations that may require re-using the samefrequency plan. When designing these types of configurations, antenna size and antenna locationare critical. If identical channel plans must be used at the same site, the same radio channel (e.g.A1 and A1) should be used at a site to minimize interference. Using alternate channels (e.g. A1 andA2) is less likely to be successful (and therefore not recommended) due to the high level oftransmitter to receiver isolation required from the antenna system.Sometimes it is required to locate the LYNX.sc radio nearby a transmitter that is the same as, orclose to the LYNX.sc receive or transmit frequencies. In this case, the LYNX.sc terminal thatshould be placed closest to this interfering transmitter should be the specific terminal with thereceive frequency which is furthest from this unwanted transmitted frequency. This approachminimizes the potential of interference. While interference conditions are rare when using theLYNX.sc radios, cases of interference may be overcome by exchanging the radios from end to endor simply reinstalling the filter unit, as described in Section 4.2 (thus swapping the frequencies ofboth ends of the radio link). In some cases, changing frequency plans (e.g. from A to B) can alsohelp mitigate any interference.Section 4.8 of this manual describes interferencecountermeasures in further detail.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-93.3.7 Power Supply PlanningThe LYNX.sc radio must have access to a supply of appropriate power, either DC or AC (if the ACadapter option has been ordered). The LYNX.sc can be powered from a DC battery system, or froma solar or generator power plant, usually with battery reserves. Typically either a positive or negativeground 24 or 48 volt supply is used. For DC, be sure the cable is of sufficient gauge to carry thenecessary current and it is less than three (3) meters (9.75 feet) in length.Before installing the radio, plan for the continuous power consumption needs in accordance with thespecifications given in Section 2.2 of this manual. It is also wise to plan for backup power for criticalcommunication circuits (including the LYNX.sc radio). Backup power allows the radios andassociated equipment to continue operation when primary power is interrupted.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-10 SECTION 3: INSTALLATION & ADJUSTMENTS3.3.8 Antenna PlanningUsing the path planning tools, proper antenna size can be determined which will yield the desiredpath performance. In general, the larger the antenna that is used with the LYNX.sc radio, the betterthe link will perform. Larger antennas have narrower beamwidth and higher gain, which will yieldbetter link performance (higher fade margin, better availability) and improve immunity to interference(due to the smaller beamwidths). However, larger antennas are more costly to purchase and installthan smaller antennas, in some cases requiring special equipment for installation. All of thesefactors should be taken into consideration when selecting antennas.In areas where transmitted output power restrictions apply, theuse of larger antennas will maintain the benefit of narrowbeamwidths and receive gain. However, output power may need tobe reduced to meet regulations. (See Section 3.13.1)Prior to installation, the specific antenna location and mounting should be determined. Thisadvanced planning also yields the transmission line requirements. Only directional antennas should be used with LYNX.sc spreadspectrum radios. These can be grid or solid parabolic antennas(minimum 2 foot - .6 meter). Flat panel antennas are alsoacceptable if the beam width is kept to a minimum.

Blank rack-mountingspaces above and below the LYNX.sc are recommended, especially if the surrounding equipmentdissipates a considerable amount of heat (over 50W).The LYNX.sc radio may be set up for mounting with the front edge projecting from the front face of astandard 19-inch rack using the rack mounting brackets enclosed with the screws in the AccessoryKit (4 per bracket). The rack mounting brackets may be reversed, in order to install for flush orcabinet mounting if preferred. Depending on rack configuration, it may be necessary to remove thefour adhesive backed rubber feet on the bottom of the unit.The LYNX.sc radio has internal fans which intake and exhauston the left and right sides of the chassis. When rack mounting,it is important to leave a small gap between the outer edges ofthe radio and the inside edge of the rack.The LYNX.sc radio may alternatively be placed on a table or shelfattached to a wall. Because of the low weight of the LYNX.sc, anymounting option other than rack mounting will be less secure.

As soon aspower is applied, the equipment will be operational. Thismeans that there can be up to 1W of RF power present atthe antenna port. The antenna port should be terminatedbefore power is applied.Power is connected using the DC power plug contained in the Accessory Kit. Use Table 3-A or 3-Balong with the associated diagram of Figure 3-7 or 3-8 to connect the DC power cables. Forexample, for a negative DC power input, use Table 3-A and Figure 3-7.NEGATIVE DC POWER INPUT(–20 TO –63 VDC)PIN FUNCTION1Power (–DC)2Ground (see figure 3-7)3Return (+DC)4Return (+DC)5Ground (see figure 3-7)6Power (–DC)Table 3-A: DC Power Connection for Negative SupplyPOSITIVE DC POWER INPUT(+20 TO +63 VDC)PIN FUNCTION1Return (–DC)2Ground (see figure 3-8)3Power (+DC)4Power (+DC)5Ground (see figure 3-8)6Return (–DC)Table 3-B: DC Power Connection for Negative SupplyPins 1 and 6 are connected together on the motherboard.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-173.7.1 DC Power WiringConnect the power cable with adequate current rating (minimum of 20 AWG) to the terminals shownon the removed (not plugged into the radio) DC power plug using the screw connections. Therecommended minimum current rating of external fuses and cables is 3 Amps. The LYNX.sc radiosconsume less than 1 Amp at ±48V and less than 2 Amps at ±24V. Be sure the DC power cable isless than 3 meters (9.75 feet) in length.Each LYNX.sc terminal should be externally fused separatelywith a 5 Amp maximum fuse. The DC power cable must be lessthan three (3) meters in length.If using negative power, connect the negative voltage to pins 1 or 6. Connect the ground returnconnection to pins 3 or 4. See Figure 3-7.If using positive power, connect the positive voltage to pins 3 or 4. Connect the ground returnconnection to pins 1 or 6. See Figure 3-8.The ground connection is available at pins 2 and 5. Either pin may be used to ground the returnside of the power supply. Do not ground both sides of the power supply.Proper grounding, either through the chassis and/or the powersupply, can be very important for protection from lightning. Agrounding screw hole is provided on the rear panel.The ground connection may be left floating if the power supply isreferenced to ground externally and to avoid ground loops insome configurations. However, this may not provide adequategrounding for lightning protection.Use a DVM (digital voltmeter) to verify voltage and polarity on the DC power plug.Do not connect the DC power plug to the rear of the LYNX.scterminal until a load is connected to the antenna port (either anRF pad, or an RF cable and antenna).

TheAC supply is equipped with a mating connector that plugs directly into the LYNX.sc radio and anAC cord with a 3-pin AC plug. The AC cord color code is shown in Figure 3-9 in case users wish toreplace the AC plug supplied with a different type of plug.Figure 3-9: AC Connection

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-20 SECTION 3: INSTALLATION & ADJUSTMENTS3.8 Antenna ConnectionThe LYNX.sc radio is equipped with an N-type female connector at the antenna port located on therear panel. A short length (~6 feet) jumper cable such as RG-214 coax (or “pigtail”) fitted with two N-type male connectors can be used to connect the antenna port to the antenna transmission line(see Section 3.9). The recommended cable type for a jumper is RG-214.A low loss 50-ohm cable (for example LDF4-50 1/2 inch coax) or EW-52 waveguide (for 5.8 GHzradios) is recommended for the antenna transmission line between the top of the rack and theantenna. The return loss presented by the transmission line at the top of the rack should be as highas possible (20 dB, minimum recommended). The length of the antenna transmission line should bekept as short as possible (to minimize losses).For 5.8 GHz radios, to minimize feeder losses, the use of 5.8 GHz elliptical waveguide isrecommended (typical loss is 1.25 dB/100 ft) for feeder lengths in excess of 200 feet. Depending onpath length and feeder length, 1/2 inch coax cable can be used with 5.8 GHz radios.For the LYNX.sc radio, 1/2” or 5/8” coaxial cable (LDF4-50 orLDF4.5-50) is recommended. Coaxial cable 7/8” or larger canexhibit moding at 5.8 GHz and is not recommended for 5.8 GHzradios. For waveguide transmission line at 5.8 GHz, EW-52waveguide is recommended. EW-63 will also work, but mayexhibit more loss.Do not use right angle N-type connectors with the 5.8 GHzLYNX.sc radios: they may present high loss at 5.8 GHz. Do notuse a low quality N-type jumper cable with the LYNX.sc. Somecable types, such as RG-8, may have high loss at 5.8 GHz.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-213.9 Transmission Line ConnectionThe transmission line feeder (such as LDF4-50 1/2 inch coax cable or EW-52 elliptical waveguide)should be prepared first by cutting to the approximate length (allowing some excess) and installingthe appropriate connector on the antenna end.The prepared transmission line is then pulled through the cable ducts, trays or conduit (as required)to the antenna, while being careful not to kink or damage the transmission line in any way.The transmission line should be supported in a tray on horizontal runs and by hangers on verticalruns. Hangers should be spaced according to the manufacturer’s instructions (typically every 5 feetunder conditions of no ice and not greater than 85 mph winds).The transmission line should be grounded using the manufacture’s recommended grounding kit.Grounding kits attach to the outer copper conductor. Grounds must be installed at the antenna, atthe bottom of the tower (if applicable) and where the transmission line enters the building. Longtransmission line runs should be grounded every 100 feet. In areas of high incidence of lightning,dissipaters should be attached to antennas. In addition, coaxial, in-line, spark-gap type, lightningsuppressors should be added at the bottom of the coax cable before entering thebuilding/enclosure.Any in-line lightning protection device must be rated for theoperating frequency of the LYNX.sc (2.4 or 5.8 GHz).After installation, the transmission line is terminated with an N-type male connector/adapterattached at the equipment end. For waveguide, this typically requires a CPR-to-N adapter.Prior to operation, the electrical integrity of the transmission line, including all connectors, can bechecked with a simple DC check between the center conductor and outer conductor. (This isneither possible, nor required for waveguide).The transmission line should ideally be connected directly to the antenna at one end and to theLYNX.sc antenna port at the other end. However, short RG-214 type pigtail jumper cables may berequired to avoid sharp bends in the transmission line to limit stress on either connection.7/8 inch coax cable or larger is not recommended for use at 5.8GHz and higher frequencies.Do not use right angle N-type connectors with the 5.8 GHzLYNX.sc radios: they may present high loss at 5.8 GHz. Do notuse a low quality N-type jumper cable with the LYNX.sc. Somecable types, such as RG-8, may have too high a loss at 5.8GHz.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-22 SECTION 3: INSTALLATION & ADJUSTMENTS3.10 Antenna Installation & AlignmentThe antenna installation consists of mounting the antenna on the tower, building roof, or otherlocation that provides line-of-sight path clearance to the far-end location. In general, antennassmaller than 2 feet diameter are not recommended for urban areas due to their wider beamwidths,which results in higher interference susceptibility. For 2.4 GHz LYNX.sc radios, a minimum of 4 foot(1.2m) diameter antennas, or larger, are recommended.Antennas should be ordered with a suitable mounting kit specific to the site requirements. Forexample, specifying round or angle tower leg adapters, or a roof tripod as necessary.If the antenna is to be mounted indoors, "looking" through a window, it is recommended that theantenna be placed approximately 12 inches away from the glass and within 10 degrees of a rightangle to the glass. The glass should be lead-free or very low-lead content type and avoid anymetallic glass coatings for best results.The antenna must be very rigidly mounted, with adequate room for azimuth and elevationadjustment.The antenna polarization must be the same at both ends of the link, either vertical or horizontal.In general, antenna mountings require a support pipe to which upper and lower support brackets areattached with “U” bolts. The antenna and optional elevation and azimuth adjustment rods are thenmounted onto the support brackets. The whole structure must be adequately grounded for lightningprotection. The antenna system must always be installed according to the manufacturer’sinstructions.Unless special test equipment is available, two operating LYNX.sc terminals are required to alignthe antennas. Alternatively, a CW generator may be used to transmit a signal toward the end underalignment.The antenna is coarse aligned using visual sighting and then fine aligned using the receive signallevel (RSL) voltage of the LYNX.sc.The RSL voltage reading can still be used to peak antennaseven if the radios have not synchronized, however far-end RSLcannot be measured from the near-end terminal until radios aresynchronized.Due to the possibility of exposure to RF radiation above the recommendedlevels, do not stand within five (5) meters of the antenna for prolonged periodsduring system operation. It is the responsibility of the installer to insure thatthe antenna is mounted in a place that is not accessible to the public.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-23To coarse align the antenna, first set it for flat elevation (no up or down tilt) using a spirit level. Thenpoint it at a heading marker obtained using a compass back-bearing from an adjacent location,(ideally, 100 feet or more away from the antenna).If a heading marker cannot be set sufficiently far away (for example when on a city building roof orlooking through a window) then a rough azimuth setting can be obtained by sighting along theantenna feed.It should be verified that both antennas are on the samepolarization by using the manufacturer’s instructions. Otherwisethe RSL will be approximately 25 to 30 dB below the calculatedlevel.Most antennas will also need fine alignment obtained using an operating link because it is veryimportant to maximize the receive RF signal level at each end of the radio link.Read Section 3.7 before applying DC power to the LYNX.sc radio.Once the coarse alignment has been set-up at both ends, then the link can be powered and somelevel of reliable communication established. The voltage at the LYNX.sc front panel RSL test pointshould be measured with a DVM to determine the relative receive RF signal level.For the fine alignment, adjusting first the azimuth and then the elevation of the local antenna willmaximize the RSL voltage. Then, the far antenna is aligned in the same way, using the RSL voltageof its local LYNX.sc radio.When aligning antennas it may be convenient to run two wires from the RSL and ground test pointsto the antenna so that the voltmeter reading is directly visible to the technicians aligning theantenna. Also, a cellular telephone or two-way radio may be useful for coordinating alignmentactivities between both ends of the link. Once the radios are coarse aligned and synchronized, thebuilt-in orderwire phone service can also be used to coordinate alignment between both ends of thelink.An orderwire telephone will provide end-to-end voice communicationsonce radios are synchronized. Synchronization usually can beaccomplished by coarse alignment only. After synchronization, theorderwire phones can be used to communicate between radio sites forantenna fine alignment. The phone interconnect cable can beextended to the antenna when desired.The larger the antenna size, the more critical alignment becomes: for example, with a 2 foot dish,the antenna can be moved ±3 degrees off the correct heading before the receive signal level dropsby 3 dB. This compares with a 6-foot dish which may only be moved ±1 degree for the samedegradation.The graph shown in Figure 3-10 shows the typical variation of RSL voltage as the receive signal levelis increased from threshold to a higher level. There is some variation between LYNX.sc receivers,but an approximate estimate of the potential RSL value may be made using this figure.

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-24 SECTION 3: INSTALLATION & ADJUSTMENTSUse the Factory Test Data Sheet shipped with your LYNX.sc terminal toobtain the best estimate of your RSL.Above 0 dBm RSL, the receiver may produce errors: however this level is rarely likely to beexceeded. A link budget calculation should be made to calculate the anticipated RSL as describedin Section 3.3.3. During anomalous propagation conditions, the RSL may fade but will not increaseup more than 10 dB (except in unusual very long paths which may fade up by 15 dB).Antenna alignment should enable the RSL to be peaked to thelevel calculated in the link budget. If the RSL is peaked but isapproximately 20 dB below the calculated level, then it is likelythat the antennas are aligned on a sidelobe of the antenna'sradiated signal. In this case, the antennas should be rotated in awide arc until the main lobe is located. (Other possible causes oflow RSL are path obstructions, loss in connectors, adapters andpigtail jumper cables or different antenna polarization at each endof the link.)Figure 3-10: Typical RSL Voltage versus Received Signal Level (RSL)

IndividualBNC connectors are used to interface the line transmit and receive functions. Seventy-five (75) ohmco-axial cables with BNC fittings should be used to connect LYNX.sc to external equipment.If a balanced 120 ohm connection (RJ45) is required, anoptional balun will provide this interface. If you can not locatethese baluns (balanced/unbalanced) devices, please consultthe factory.The DATA OUT port provides a bipolar signal (positive and negative pulses) referenced toground, with the BNC shield connected to ground.However, the DATA IN port accepts a similar bipolar signal with the BNC shield normally left OPEN(floating) in order to eliminate any ground loop problems. If desired, the BNC shield on the DATA INport may be grounded using the selector switch SW2.Position Description Setting1Grounding Condition Channel 1 0 = Floating1 = Grounded2Grounding Condition Channel 2* 0 = Floating1 = Grounded3Grounding Condition Channel 3* 0 = Floating1 = Grounded4Grounding Condition Channel 4* 0 = Floating1 = Grounded* Where applicableFigure 3-11: CEPT-1 Interface Grounding Switch

TheDIP switches must be set to match the filter assembly that is mounted on the radio. For single anddouble capacity models, positions 5,6 and 7 define the frequency channel plan of the radio (e.g. A,B, C), the last DIP switch defines the transmit channel of the radio (e.g. A1 or A2).Radios are shipped from the factory with their DIP switch segments set to match the installed filter.In most cases, no modification of these switches is required.` Also, there are labels on the RF filterillustrating the correct DIP switch settings. One label is right side up and the other is upside down.Set the DIP switch settings for the label that is right side up. If a new filter is installed, or theexisting filter is rotated for opposite channel configuration (e.g. A1 to A2), reset the DIP switches tomatch the right side up label on the filter. Refer to Section 4.2 for more information.The radio channel selection is user adjustable by removing and replacing, or reversing the filterassembly. This allows units of the same radio model to be used as spares for several channels. Forexample, if a network of LYNX.sc radios has several radios using all three E1 channel plans at 5.8GHz, a single spare unit of any channel plan can be used to spare all the radios. If a radio failurewere to occur in the network, the filter assembly of the failed unit would be removed and replace thefilter assembly in the spare radio. The DIP switch segments on the spare may need to change tomatch the installed filter and the spare radio could be put into service.The DIP switch setting must match the filter assembly mounted on theradio. Also, both radios of a link must have opposite channel plans (e.g.A1 and A2).Consult Section 4.2 of this manual for more information on changing RFchannels. Consult Appendix B for proper frequency channel switchsettings.Other NON-standard frequency plans may be offered in the future. Inthese cases, follow the DIP switch setting on the filter label.

A single DIP switch segment on SW1 as shown in Figure 3-12,allows the operator to select the use of either the internal or an external test signal. The factorysetting for loopback mode is internal.Figure 3-12: Loopback Mode Selection

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-28 SECTION 3: INSTALLATION & ADJUSTMENTS3.12.3 Spreading Code SelectionThe spreading code is the pseudo-random chip sequence that is mixed with the data to produce thespread spectrum signal. The spreading code is generated by the LYNX.sc radio internally. Differentcodes can be selected using the DIP switches on the LYNX.sc radio rear panel.The spreading code must be the same for both ends of a radiolink.The spreading code has no effect with the Model 31850 (4xE1) 3-channel LYNX.sc.Spreading codes are all set in the factory to code 1. Should the code need to be changed, thenboth ends of the link must be changed.Changing the spreading code is an out-of-service adjustment. There are two DIP switch segmentson SW3 located on the rear panel which select the spreading codes. See Figure 3-13 for DIP switchsegment settings.Figure 3-13: Spreading Code Selection

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-293.12.4 Input Alarm (Data Loss) Enable/DisableThe LYNX.sc radio provides a capability to enable or disable input alarms (Data Loss). On the frontpanel and over the alarm and diagnostic interfaces, an alarm condition is normally generated if thereis no input data signal (E1) to the radio. For example, in the case of the double E1 capacity model,the radio may have been installed in a location only requiring one E1 signal for traffic while thesecond E1 channel has been left idle (for future planned expansion). In this case, it may bedesirable to disable the input alarm to the second channel so that local and remote alarms are notregularly generated by the (known) lack of this data input. When the network is later expanded toinclude traffic on the second E1, this switch can be set to enable the input data alarm condition.See Figure 3-14 for DIP switch segment settings for the 4xE1 model. Refer to appendix B for allmodels.When a DATA LOSS alarm condition occurs, the LYNX.sc radiowill inject AIS into the incoming data stream, even if the inputalarm has been disabled.1xE1 and 2xE1 Models:On SW1, switch segment(s) 1 (and 2) apply to channels 1 and 2 respectively.4xE1 Model:On SW3, switch segment 3 applies to Channel 3 input while switch segment 4 applies to Channel 4input.Figure 3-14: Input Alarm Disable Switch

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-30 SECTION 3: INSTALLATION & ADJUSTMENTS3.12.5 AIS Enable/DisableAIS (Alarm Indication Signal) is the blue code (all 1’s) that keeps the digital line interface activeunder data loss conditions. AIS is required by certain equipment to maintain synchronization (forexample, it is required on all leased line circuits). However, it is not required by all equipment (forexample, a CSU/DSU will initiate its own blue code to the line under data loss conditions).Under test conditions, when measuring receive threshold, for example, it may be necessary, todisable AIS to facilitate BER measurement.There is a user selectable DIP switch segment on the rear panel of the LYNX.sc radio that includesselection of the AIS function (on/off) at the receiver line output. When the AIS is selected (on), theCEPT-1 signal will send blue code to the line when the received BER exceeds 1 x 10-3. Thisfunction is similar to a data “mute” function. When the AIS is disabled (off), no insertion of data willtake place unless an RX SYNC alarm condition occurs. Refer to Figure 3-15 for DIP switch segmentinformation.The standard factory setting is to have the demodulator AIS alarm selected ON because it preventsa severely errored signal (possibly unsynchronized) from being sent out to the line.It is recommended that AIS be selected ON for normal operation.It is recommended that AIS be selected OFF for measuring BERat threshold.This DIP switch does not affect AIS injection into thetransmitted data stream upon a DATA LOSS condition.Figure 3-15: AIS Switch

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-313.13 System Turn-up to Service1. Prior to installing the system, it may be desirable to perform a back-to-back test of theLYNX.sc radio pair. Consult Section 4.9 for further details. Back-to-back testing is a simpleway to verify that the LYNX.sc radios are fully operational before they are installed.Installation adds several variables (such as antenna alignment) which can lead to systemturn-up delays. Also, during back-to-back testing, the DIP switch settings and someconnections can be tested. This step can eliminate a majority of troubleshooting once theradios are installed.A cellular phone or two-way radio system (walkie talkie, CB,mobile radio) can be very useful during installation. Thesecan be used for temporary near-end and far-endcommunications between the installation personnel at onesite and installation personnel at the other site while installingthe system. These can also be helpful for communicationbetween a person at the top of a very tall tower and groundpersonnel.The LYNX.sc radio incorporates an internal Orderwire featurethat provides end-to-end “telephone” style communications.However, the link must be partially operational to use thisfeature. In lieu of, or in addition to the use of cellular phonesor two-way radio, this Orderwire feature can also be very usefulfor installation, but typically cannot be put into service untilstep 8 or 9 of this procedure is completed. See Section 3.14.1for more details.2. Perform a general alignment of the antennas on both ends of the path using binoculars,compass or other related tools. It is important to have the antennas aligned as accuratelyas possible before putting radio traffic over the link. This will help in getting the systemrunning more rapidly. See Section 3.10 for more details.3. Connect the transmission line to the antenna, and feed it to the LYNX.sc radio location(see Section 3.9). Connect the opposite end of the transmission line to the N-type femaleconnector located on the filter assembly which occupies the top half of the LYNX.sc rearpanel. The connection must be terminated into an antenna or a load before DC power isapplied to the radio.4. Verify that DIP switch settings for frequency channel selection match that of the filter that isinstalled on the rear of the radio. Consult 3.12.1 for further details. The far-end radio musthave the same channel plan (e.g. A, B, C) as the near-end radio, and the opposite Tx andRx frequencies (e.g. A1 and A2 make up a matched pair of radios).5. Verify that the DIP switch settings for spreading code are the same for both ends of theradio link (see Section 3.12.3).6. With the DC power source active, but not plugged into the LYNX.sc radio, using avoltmeter, confirm that the DC mating connector has the proper power connections in

INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999PAGE 3-32 SECTION 3: INSTALLATION & ADJUSTMENTSaccordance with Section 3.7. Verify the polarity and the absolute voltage on all pins. Verifyground connection for power.7. Connect power to the LYNX.sc radio. Verify that the Front Panel “ON” LED indication isilluminated. This confirms that power has been properly applied.Ensure that the RF Antenna port connection is properlyterminated before applying power to the LYNX.sc terminal, as instep 3.When the LYNX.sc radio is initially powered-on, some alarmconditions may be present. This is normal and alarms can beignored at this time.8. Place a voltmeter across the GND and PWR front panel test points. See Figure 3-16 and 3-17 for voltage setting information and Table 3-C for typical output power levels for givencable lengths where EIRP limits apply. If necessary, use a small screwdriver at the frontpanel receptacle to adjust the output power of the local transmitter in accordance with thepath analysis calculations. The recessed potentiometer is rotated clockwise to increasetransmit output power and counter clockwise to decrease transmit output power. Afterverifying correct setting of the transmit output power, disconnect the voltmeter. Place thecover cap found in the installation accessory kit over the front panel receptacle.The LYNX.sc radio requires professional installation. With someLYNX.sc models, in certain countries, there may be EffectiveIsotropic Radiated Power (EIRP) limits which dictate themaximum output power that the LYNX.sc radio can transmit giventhe transmission line loss and the gain of the antenna. Consultwith appropriate government agencies or Western Multiplex ifthere is any question regarding maximum output power allowed.In the USA, 5.8 GHz models may be operated at full power. 2.4GHz models may require a power reduction of 1 dB from +30 dBminput power, as measured at the antenna feed, for every 3 dB thatthe antenna gain exceeds +6 dB. See Section 3.3.3 and Tables 3-C or 3-D for more details.

$INSTALLATION AND MAINTENANCE MANUALLYNX.sc E1 FAMILYSPREAD SPECTRUM RADIOSSEPTEMBER 1999SECTION 3: INSTALLATION & ADJUSTMENTS PAGE 3-35For precision measurement of transmit output power, it is best toconnect an RF power meter to the antenna port. The PWR portvoltage may not provide enough precision. This is especiallyimportant where EIRP limits apply to the installation.In cases of no EIRP limits, the radio transmitter output powercan be adjusted to maximum for installation, except for veryshort paths using very high gain antennas, where excessivepower may not be advised.Don’t forget that the RF output port should be terminated at alltimes when power is applied to the LYNX.sc radio. Therefore,disconnect power to the radio before connecting a power meterand reapply power once connected. Often, an RF power metermay have a limit to the input power that it can measure withoutdamage. It is advised to place a calibrated fixed value RFattenuator (typically 20 dB or more) between the LYNX.sc radioand the power meter to assure proper operation and safety for theRF power meter. The value of this fixed attenuation can then beadded to the value of the RF power meter reading to obtain theactual LYNX.sc radio transmitter output power.9. Connect a voltmeter across the GND and RSL front panel test points. This voltage readingcorresponds to the Received Signal Level (RSL) of the near-end radio. In other words, RSLis the “amount” of signal the near-end radio is receiving from the far-end radio. Since theantennas have not been finely aligned, it is not expected at this time that the RSL will readvery high. However, at this point it can be verified that some communication is taking placebetween the two LYNX.sc terminals. Use the RSL voltage reading to align the antennas.Align one antenna at a time in accordance with Section 3.10. Complete alignment of bothends of the radio link before going further.The RSL voltage output on the radio's front panel will output avoltage range over the full receiving capability of the radio(approximately 10 VDC at 0 dBm to 0.0 VDC at threshold).The LYNX.sc radio has a unique feature of allowing measurement of the far-end RSL from the near-end radio. This is only possible if the LYNX.sc radios are communicating (the RSL is abovethreshold). The far-end RSL can be used to verify that adjustments to local antenna alignment arecorresponding to the far-end radio reception. Far-end RSL is measured by pressing and holding theDISPLAY FAR END front panel button. While this button is held, the RSL voltage indicates the RSLof the far-end radio. RSL of both ends should be verified to be within approximately 2 dB of predictedvalue (see Section 3.3.3). There are several factors that can contribute to low RSL:-Incorrect antenna alignment (aligned on a lobe and not on the main signal)-Improper polarization alignment of antennas (horizontal vs. vertical)-Transmission line problems (loose connections, bent or damaged cables, lossy adapters)-Path obstructions (trees, buildings, hills, etc.)-Path clearance (line-of-sight, earth curvature, Fresnel zone, diffraction and partial$
