120 20110-132 GeminiPD Installation Guide32. Installation2.1 Planning the Installation2.1.1 OverviewTo ensure trouble-free, efficient installation,start by inspecting the vehicle to determinethe optimum position for GeminiPD and itsantennas as well as the routing of all associ-ated cabling and wiring.2.1.2 LocationOften, installations in cars are done in thetrunk, underneath the back window ledge oron the trunk floor. In vans and small trucks,it is usually done in the back of the vehicle.In large vehicles, it is often done in the frontcabin.Be sure to place the GeminiPD unit in such away that:• The LEDs can be seen (as an aid introubleshooting)• Access to the antenna DE-9 connectorsis possible without removing the unit• Sufficient air may flow around the unitto provide adequate coolingGeminiPD is not fully waterproof, therefore itshould be mounted sufficiently away from anopened trunk lid or opened tailgate, windowsor doors to avoid exposure to rain and/orsnow. It also minimizes the chance that mate-rial can be accidentally thrown on the unit orof someone bumping against it.2.1.3 Cable PathTry to route the cables away from locationswhere they would be exposed to heat (ex-haust pipes, mufflers, tailpipes, etc.), batteryacid, sharp edges, mechanical damage orwhere they would be a nuisance to automo-bile mechanics, the driver or the passengers.Keep wiring away from automotive com-puter modules, other electronic modules andignition circuits to help prevent interferencebetween these components and radio equip-ment.Try using existing holes in firewall and trunkwall and the channels above and below orbeneath the doors, channels through doorsand window columns that are convenient torun cables and wires.Whenever possible, install conduit in whichto run the cables.2.2 WarningsBefore starting installation, review all of thefollowing warnings.2.2.1 RF Radiation warningThe Federal Communications Commission(FCC), with its action in the General Docket,79-144, March 13, 1985, has adopted asafety standard for the human exposure toradio frequency electromagnetic energyemitted by FCC-regulated equipment. Onlyproper installation of the transceiver antennaof GeminiPD as summarized in section 2.5will result in user exposure substantiallybelow the FCC recommended limits.Antennas installation must be done by quali-fied personnel. See paragraph 2.5.2 for rec-ommended antenna positioning.Transmissions when persons or animals out-side the vehicle are within two feet of theantenna may result in radio energy radiationburns or related injuries.2.2.2 Interference with vehicularelectronicsCertain vehicle electronic devices may beprone to malfunction due to lack of protec-tion from radio frequency energy presentwhen transmitting. It includes, and is not limited to:- Electronic fuel injection systems- Electronic anti-skid braking systems- Electronic cruise control systems
120 20110-132 GeminiPD Installation Guide4If the installation vehicle contains suchequipment, consult the dealer for the makeof vehicle and enlist his aid in determining ifsuch electronic circuits will perform nor-mally when the radio is transmitting.2.2.3 Secure mountingFor vehicle occupant(s) safety, mount Gem-iniPD securely so that the unit will not breakloose in case of an accident or violent ma-neuvers.2.2.4 Explosive environmentsOperation of vehicular radio transmitters inexplosive environments may be hazardousand conventional safety precautions mustprevail. These include and are not limited to:- Transmitting while fuelling the vehicle.Do not carry fuel containers in the samecompartment as GeminiPD.- Dynamite blasting caps may explodewhen transmitting radio operation takesplace within 500 feet. Always obey the“Turn Off Two-Way Radios” signsposted at sites where dynamite is beingused.If transporting blasting caps:a) Carry the blasting caps in an appropriatemetal container having a soft cushioninglining.b) Suppress transmissions whenever theblasting caps container is being loadedor unloaded into or from the vehicle.Check applicable local bylaws.2.2.5 Installation in vehiclespowered by liquefied gas.GeminiPD installations in vehicles poweredby liquefied petroleum gas with the LP-gascontainer in the trunk or other sealed-offspace within the interior of the vehicle mustconform to the National Fire Protection As-sociation Standard NFPA 58 which requires:- Space containing radio equipment shallbe isolated by a seal from the spacecontaining the LP-gas container and itsfittings.- Outside filling connections shall be usedfor the LP-gas container.The LP-gas container space shall be ventedto the outside of the vehicle.2.3 Physical Unit2.3.1 Recommended tools andsupplies• Electric drill for mounting holes• Hammer and center punch• Tie-wraps• Drills and circle cutters as needed ac-cording the size of screws (or nuts andbolts) used.• In-line “Power meter” capable of meas-uring forward and reflected power at theoperating frequency of the radio.2.3.2 Physical mounting ofGeminiPDStart by running all the cables (DC power,PC RS-232 as well as all antennas cabling)prior to mounting GeminiPD to assure thefeasibility of the planned cable routing. Besure to leave sufficient slack in each cableso the GeminiPD may be removed from themounting bracket for servicing with thepower applied and the antenna attached.GeminiPD is ready for installation.Cautions:• When drilling mountingholes, be careful to avoid dam-aging some vital part of the ve-hicle such as fuel tanks, trans-mission housing etc. Alwayscheck how far the mountingscrews extend below themounting surface prior to in-stallation.• Use of drill bit stops ishighly recommended.• After drilling, remove allmetal shavings before installingscrews.
120 20110-132 GeminiPD Installation Guide5• Do not overtighten self-tapping screws.1. Once you have found a suitable mount-ing position for GeminiPD, hold the unitand the unattached mounting bracket inthe proposed mounting position andcheck that there is clearance behind theunit for the heatsink, cables, etc. Checkthat the position provides a large enoughflat surface that the bracket will not bedistorted when installed.Figure 1 - Mounting plate and slot dimensions2. Using the installation bracket as a tem-plate, mark the four locations for drilling(see Figure 1). Again, ensure that drillingat the selected points is safe and will notcause damage.3. Indent the drilling positions with a centerpunch.4. Drill holes sized for the self-tappingscrews or for the nuts, bolts and lockwashers used.Caution: Slightly reduce the size of thedrilled holes when using self-tappingscrews in thin metal.Figure 2 - Bracket installation5. Install the bracket without distorting.6. Securely mount GeminiPD to the installedbracket using the four supplied 8x40black machine screws.7. Drill any additional holes as required forrouting all cables and fit holes withsuitable grommets or bushings wheneverrequired.2.4 Electrical installation2.4.1 Electrical requirementsGeminiPD is designed to operate from a13.8Vdc nominal car battery (negativeground) and requires currents up to 15.0A. Itwill tolerate a supply voltage range of 10.9volts to 16.3 volts.In vehicles with a 24 VDC electrical system(mostly in trucks), it is essential to provide asuitably rated 24/12 VDC converter to iso-late the unit from the battery and protect itagainst excessive voltage.Warnings:Application of more than 16.3 VDCwill damage GeminiPD and is notcovered by the warranty.Always disconnect GeminiPD’s DCpower lead before connecting asecond battery, using power fromanother vehicle or power boosting(e.g. when “jump starting” the ve-hicle).2.4.2 Routing of power cable1. Start by disconnecting the vehicle’s bat-tery unless specifically prohibited fromdoing so by the customer, vehicle manu-facturer, agent or supplier.Note:In this event, exercise ex-treme caution throughoutthe installation and fit thefuse only when the installa-tion is complete.2. The 22 feet (6.7 meters) long power ca-ble consists of three wires attached to aPackard Electric “Weather-Pack” con-nector (DC power Connector).2.5"6.0"1.0"0.2"
120 20110-132 GeminiPD Installation Guide6The DC Power connector has:• At position “A”, the smaller redswitch-sense wire (commonly to ignition)• At position “B”, the blue ground wire• At position “C”, a larger red B+ DCpower wire (MUST be unswitched)Figure 3 - DC Power Connector3. Place this connector at GeminiPD’s radiopower input location. Do not connect atthis time. See paragraph 2.6, “Complet-ing the physical installation”.4. Carefully route both the B and the Cwires to where the in-line fuse holderwill be installed, usually as close to thevehicle’s battery as practicable. Ensurethat leads do not chafe on any metalpart(s). Secure the wires at several loca-tions along their length.Caution:Use proper crimping tool.Common pliers are NOTacceptable.Warning:The DC Power lead must beunswitched5. Insert the negative (blue) lead into one ofthe appropriate connector lug and crimpsolidly to force the metal contacts ontothe wires.6. Repeat the step above for connecting thered DC power lead.7. Attach the positive lead at the batterypositive terminal. Attach the negativewire at the vehicle end of the batteryground cable. If the negative cable isconnected directly to the battery nega-tive terminal, it should be fused in caseof failure of the vehicle’s ground cable.Ensure tight and secure connections.8. Fasten the fuse holder and leads.9. Carefully route the A wire to where theconnection will be made for switchsensing.• Connect to “Ignition” if you wish tohave GeminiPD turning ON and OFFdependent on the vehicle’s ignitionkey.• Connect to “Accessory” if you wishGeminiPD to be available when theengine is not running, but still de-pendent on the ignition key.• Connect to a user-supplied controlswitch.• In installations equipped with a“ChargeGuard”, connect to the con-trolled-side of the ChargeGuard(remembering that the DC Powerlead must NOT be switched).10. Make appropriate connections.Cautions:Where scraping to bare metal wasrequired, and at the battery postswhere wire ends and lugs may beexposed, apply anti-corrosion com-pound.Insert the fuse only when installa-tion is complete and ready to test.11. At the GeminiPD position, neatly coilcable slack and attach securely.ABCIGNITION(Small red wire)GROUND(Blue wire)13.8VDC B+ (Fused Red wire) SEAL(DO NOT REMOVE)
120 20110-132 GeminiPD Installation Guide72.5 AntennaTo meet the FCC’s RF Exposure Guidelines,the main transmitter antenna must be vehicle-mounted to provide a separation distance of20 cm or more from all persons and the an-tenna gain, including cable loss, must notexceed 2.73dBd (4.477dBi) for satisfying RFexposure requirements.2.5.1 Recommended tools andsupplies• circle cutter• hole saw or• socket punch for antenna• Mini-UHF Crimp tool2.5.2 PlanningReferring to Figure 4, GeminiPD commonlyuses three separate antennas:• “T” - Main transceiver -Constraints are Maximum PermissiveExposure (“MPE” on the drawing) limitsof 20 cm (as per see section 2.5 above)and omni-directional factors• “R” - Auxiliary receiver –Constraints are the receiver spacing of atleast 5/8 λ (wavelength) from trans-ceiver antenna and omni-directional re-quirements• “G” - Global Positioning System (GPS)Constraints are TX spacing of at least24-in/60.96 cm from all transmitting an-tennas and a clear view of the sky.For the optimum antenna spacing at the fre-quency you are using, consult System Engi-neering.For installation of ground-plane dependentantennas, the center of the metal surfaceused for mounting is preferable for bestomni-directional pattern.For ground-plane independent antennas, in-stallation may be close to the edges of thesurface.Figure 4 - Antenna spacingInstall the antennas in one of the followingpositions:- Most preferred for all antennas: center-line of roof. For transmitter antenna, it isthe ONLY acceptable position.- Less preferred for receiver antenna:trunk lid, providing distance to transmit-ting antenna is respected whether lid isopened or closed.- Much less preferred, but permissible forreceiver antenna: left or right rear fend-ers, just in back of rear window- Least preferred, but permissible for re-ceiver antenna: left or right front fenders,ahead of windshieldNote: Proximity to other vehicle-mountedantennas may cause mutual inter-ference especially at higher fre-quencies.2.5.3 Antenna Installation1. Route good quality 50-ohm coaxial ca-bles (e.g. RG-223) from each of the se-lected antenna positions to the positionwhere the GeminiPD unit is mounted.2. Terminate the end at each of the antennapositions with the appropriate connectorMPE ≥≥≥≥5/8λλλλ(UHF: 18"/46cm800MHz: 9"/23cm)7.9in. / 20cm≥≥≥≥24in.T RG
120 20110-132 GeminiPD Installation Guide8for the antenna used and make the con-nection.3. At the GeminiPD position, cut the threecables to length and terminate with theappropriate plug. For the transceiver andthe auxiliary cables, use a Mini-UHFcrimp plug using an appropriate crimpingtool. For the GPS, use a SMA connec-tor.4. Positively identify the transceiver mini-UHF plug and connect to the left rear ofGeminiPD.5. Positively identify the auxiliary receivermini-UHF plug and connect to the frontleft of GeminiPD to the RX position.6. Connect the SMA connector to the GPSposition below the auxiliary connectorposition.7. Do not skip this last step, trust us; it isan important one. To complete the in-stallation, tie-wrap together the auxiliaryand the GPS antenna cables at a pointabout two inches in front of the unit. Itwill be much easier hereafter to cor-rectly identify which mini-UHF pluggoes where. You DO NOT want to crossthe auxiliary plug with the transceiverplug.2.6. Completing thephysical Installation.To complete the physical installation andprior to testing GeminiPD:• Connect DC Power cable’s connector toGeminiPD’s until you hear a click as thetwo parts snap together.• Re-check that all other connections aresecure (antennas, PC, etc.)• Switch vehicle ignition ON.You are now ready to check for normal op-eration and to run the Radio InstallationSoftware (RIS) program for testing or trou-ble-shooting.2.7. Checking out NormaloperationCheck that the vehicle ignition is ON.1. Check for proper operation of theGeminiPD’s LEDs as per Table 1 in sec-tion 3.12. Using the RIS program (described insection 4) and an in-line wattmeter,check forward & reverse power to con-firm main antenna installation.3. Using the RIS, check the RF link with abase station that can be heard by usingthe RIS “Ping” feature.4. See paragraph 4.4.4.4 orIf user application and its base stationare available, test the installation bygoing through a normal sequence oftransmitting and receiving messages.

This field may be leftblank.On subsequent Get, Get As or Put From, thisfield displays entered comments. If no commentwas entered, the field will remain blank.4.4.3.3 PasswordThe password feature is useful where two (ormore) fleets share the same radio channel. Mo-biles without the proper password would stillreceive the message but the contents would notbe intelligible.1- Type your password directly in the “Pass-word” field. It is a string of 32 hexadecimalcharacters (exactly).2- Press the button “Put Password” to make theentry permanent. This field may be leftblank.On subsequent Get, Get As or Put From, thisfield will require that the correct password beentered. If none was entered, the field will re-main blank.Password information is NOT retrieved andsaved to a file, along with the configuration.Clearing a Password is done by entering 32 zeros.The Dataradio supplied password algorithm isdesigned to thwart the casual observer only. Itprovides a limited form of data privacy. There-fore, if your security requirements are high, Da-taradio urges you to use external encryptiontechnology (such as Data Encryption Standard(DES)) in the Host and Mobiles computers.

Trouble-Shooting andTestingThe checks described below should be done atannual intervals or whenever deterioration in per-formance is noted.5.1 Equipment Required• 13.8 VDC (nominal) car battery, or13.8 VDC/20A regulated power supply (Inthe case the unit is not installed in a vehicle)• In-line watt meter (50W range)• Radio service monitor (IFR or equivalent).• Cable with mini-UHF male connector toconnect GeminiPD to the service monitor.5.2 Basic TestsRecommended checks:1. Transmit and Reverse power output2. Carrier frequency error3. Frequency deviation4. Receivers RSSI Check5. Link test between Gemini and the base sta-tion.6. GPS testRefer to Table 4 for checks 1 to 5.Important note: Before proceeding make surethat the service monitor has been calibratedrecently and has warmed up for at least thetime specified by its manufacturer.Some reported frequency and deviation prob-lems have actually been erroneous indicationsfrom service monitors that have not adequatelywarmed up. This is particularly likely whenfield service is done during winter monthsRefer to the RIS section for functiondetails5.3 GPS TestAbout three minutes after ignition is turned-on,the PWR LED on the GeminiPD front panelshould flash in amber color at the rate of onepulse per second.1 This indicates that the GPShas acquired the sky position of a sufficientnumber of satellites to arrive at a ground posi-tion solution.If the GPS has a good view of the sky and stillhas not generated any position solution withinthree minutes (it may take up to 10 minutes ormore if the sky view is partially blocked.), thefollowing trouble-shooting procedures should beundertaken to isolate the fault:1) Disconnect the GPS antenna cable connectorfrom the Gemini radio and check for + 5VDC on the center pin of the GPS antennaconnector on the radio using a Digital Volt-Meter (DVM). If the voltage is present, do notreconnect the cable and proceed to step 2.2) With the DVM, measure resistance betweenthe shell and the center conductor of the GPScable, resistance should be between 100 and300 Ohms, if it measures open or short circuitthe GPS antenna is either a passive antennawhich is the WRONG type, or a defectiveactive antenna, replace with a known goodactive antenna.3) Connect the new antenna to Gemini and waitabout three minutes for the POSITIONACQUIRED indicator to start flashing onGeminiPD, if not, the Gemini radio or its GPSreceiver is defective 1 Lit green and flashing amber for the 800MHz model un-der 2% duty cycle limit.
