122 20130-003 G3 Installation Guide91.6 UnpackingWhen ready for installation, carefully unpack your G3 kit (p/n 023 6000-101) shipping carton and iden-tify each item as listed below:• One G3• Installation mounting bracket• Power cable – 22 feet (6.7 meters)• Small parts kitIf damage has occurred to the equipment during shipment, file a claim with the carrier immediately.2. Installation2.1 Planning the Installation2.1.1 OverviewTo ensure trouble-free, efficient installation, start by inspecting the vehicle to determine the optimumposition for G3 and its antennas as well as the routing of all associated cabling and wiring.2.1.2 LocationOften, installations in cars are done in the trunk, underneath the back window ledge or on 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 inthe front cabin.Be sure to place the G3 unit in such a way that:• The LEDs can be seen (as an aid in troubleshooting)• Access to the antenna connectors is possible without removing the unit• Sufficient air may flow around the unit to provide adequate coolingG3 is not fully waterproof, therefore it should be mounted sufficiently away from an opened trunk lid oropened tailgate, windows or doors to avoid exposure to rain and/or snow. It also minimizes the chancethat material can be accidentally thrown on the unit or of someone bumping against it.2.1.3 Cable PathTry to route the cables away from locations where they would be exposed to heat (exhaust pipes, muf-flers, tailpipes, etc.), battery acid, sharp edges, mechanical damage or where they would be a nuisance toautomobile mechanics, the driver or the passengers.Keep wiring away from automotive computer modules, other electronic modules and ignition circuits tohelp prevent interference between these components and radio equipment.Try using existing holes in firewall and trunk wall and the channels above and below or beneath thedoors, channels through doors and window columns that are convenient to run cables and wires.Whenever possible, install conduit in which to run the cables.
122 20130-003 G3 Installation Guide102.2 WarningsBefore starting installation, review all of the following warnings.2.2.1 RF Radiation warningRecommended safety guidelines for the human exposure to radio frequency electromagnetic energy arecontained in the Canadian Safety Code 6 and the Federal Communications Commission (FCC) Bulletin65. Proper installation of the transceiver antenna of G3 as summarized in section 2.5 will result in userexposure substantially below the recommended limits for the general public.Qualified personnel must do all antenna installations. See paragraph 2.5.2 for recommended antennapositioning.Transmissions when persons or animals outside the vehicle are within two feet of the antenna may resultin radio energy radiation burns or related injuries.2.2.2 Interference with vehicular electronicsCertain vehicle electronic devices may be prone to malfunction due to lack of protection from radio fre-quency energy present when transmitting. It includes, and is not limited to:• Electronic fuel injection systems• Electronic anti-skid braking systems• Electronic cruise control systemsIf the installation vehicle contains such equipment, consult the dealer for the make of vehicle and enlisthis aid in determining if such electronic circuits will perform normally when the radio is transmitting.2.2.3 Secure mountingFor vehicle occupant(s) safety, mount G3 securely so that the unit will not break loose in case of an acci-dent or violent maneuvers.2.2.4 Explosive environmentsOperation of vehicular radio transmitters in explosive environments may be hazardous and conventionalsafety precautions must prevail. These include and are not limited to:• Transmitting while fuelling the vehicle. Do not carry fuel containers in the same compartment asG3.• Dynamite blasting caps may explode when transmitting radio operation takes place within 500feet. Always obey the “Turn Off Two-Way Radios” signs posted at sites where dynamite isbeing used.If transporting blasting caps:a) Carry the blasting caps in an appropriate metal container having a soft cushioning lining.b) Suppress transmissions whenever the blasting caps container is being loaded or unloaded into orfrom the vehicle.Check applicable local bylaws.2.2.5 Installation in vehicles powered by liquefied gas.G3 installations in vehicles powered by liquefied petroleum gas with the LP-gas container in the trunk orother sealed-off space within the interior of the vehicle must conform to the National Fire Protection As-sociation Standard NFPA 58 which requires:• Space containing radio equipment shall be isolated by a seal from the space containing the LP-gas container and its fittings.
122 20130-003 G3 Installation Guide11• Outside filling connections shall be used for the LP-gas container.The LP-gas container space shall be vented to the outside of the vehicle.2.3 Physical Unit2.3.1 Recommended tools and supplies• Electric drill for mounting holes• Hammer and center punch• Tie-wraps• Drills and circle cutters as needed according the size of screws (or nuts and bolts) used.• In-line “Power meter” capable of measuring forward and reflected power at the operating fre-quency of the radio.2.3.2 Physical mounting of G3a) Start by running all the cables (DC power, PC RS-232 as well as all antennas cabling) prior tomounting G3 to assure the feasibility of the planned cable routing.b) Be sure to leave sufficient slack in each cable so the G3 may be removed from the mountingbracket for servicing with the power applied and the antenna attached.c) G3 is ready for installation.Cautions:• When drilling mounting holes, be careful to avoid damaging some vital part of the vehi-cle such as fuel tanks, transmission housing etc. Always check how far the mountingscrews extend below the mounting surface prior to installation.• Use of drill bit stops is highly recommended.• After drilling, remove all metal shavings before installing screws.• Do not overtighten self-tapping screws.1. Once you have found a suitable mounting position for G3, hold the unit and the unattached mountingbracket in the proposed mounting position and check that there is clearance behind the unit for theheatsink, cables, etc. Check that the position provides a large enough flat surface that the bracket willnot be distorted when installed.Figure 1 - Mounting plate and slot dimensions2. Using the installation bracket as a template, mark the four locations for drilling (see Figure 1). Again,ensure that drilling at the selected points is safe and will not cause damage.3. Indent the drilling positions with a center punch.4. Drill holes sized for the self-tapping screws or for the nuts, bolts and lock washers used.Caution: Slightly reduce the size of the drilled holes when using self-tapping screws in thin metal.2.5"6.0"1.0"0.2"
122 20130-003 G3 Installation Guide12Figure 2 - Bracket installation5. Install the bracket without distorting (see Figure 2).6. Securely mount G3 to the installed bracket using the four supplied 8x40 black machine screws.7. Drill any additional holes as required for routing all cables and fit holes with suitable grommets orbushings whenever required.2.4 Electrical installation2.4.1 Electrical requirementsG3 is designed to operate from a 13.8Vdc nominal car battery (negative ground) and requires currents upto 12.0A. It will tolerate a supply voltage range of 10.9 volts to 16.3 volts.In vehicles with a 24 VDC electrical system (mostly in trucks), it is essential to provide a suitably rated24/12 VDC converter to isolate the unit from the battery and protect it against excessive voltage.Warnings:Always disconnect G3’s DC power lead before connecting a second battery, using power fromanother vehicle or power boosting (e.g. when “jump starting” the vehicle).2.4.2 Routing of power cable1. Start by disconnecting the vehicle’s battery unless specifically prohibited from doing so by thecustomer, vehicle manufacturer, agent or supplier.Note:In this event, exercise extreme caution throughout the installation and fit the fuse onlywhen the installation is complete.2. The 22 feet (6.7 meters) long power cable consists of three wires attached to a Packard Electric“Weather-Pack” connector (DC power Connector, see Figure 3).Figure 3 - DC Power ConnectorThe DC Power connector has:• At position “A”, the smaller red switch-sense wire (commonly to ignition)• At position “B”, the blue ground wire• At position “C”, a larger red B+ DC power wire (MUST be unswitched)ABCIGNITION(Small red wire)GROUND(Blue wire)13.8VDC B+ (Fused Red wire) SEAL(DO NOT REMOVE)
122 20130-003 G3 Installation Guide133. Place this connector at G3’s radio power input location. Do not connect at this time. See paragraph2.6, “Completing the physical installation”.4. Carefully route both the B and the C wires to where the in-line fuse holder will be installed, usuallyas close to the vehicle’s battery as practicable. Ensure that leads do not chafe on any metal part(s).Secure the wires at several locations along their length.Caution:Use proper crimping tool. Common pliers are NOT acceptable.Warning:The DC Power lead must be unswitched5. Insert the negative (blue) lead into one of the appropriate connector lug and crimp solidly to force themetal contacts onto the wires.6. Repeat the step above for connecting the red DC power lead.7. Attach the positive lead at the battery positive terminal. Attach the negative wire at the vehicle end ofthe battery ground cable.If the negative cable is connected directly to the battery negative terminal, it should be fused incase of 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 the connection will be made for switch sensing.• Connect to “Ignition” if you wish to have G3 turning ON and OFF dependent on the vehicle’s ig-nition key.• Connect to “Accessory” if you wish G3 to be available when the engine is not running, but stilldependent on the ignition key.• Connect to a user-supplied control switch.• In installations equipped with a “ChargeGuard”, connect to the controlled-side of the Char-geGuard (remembering that the DC Power lead must NOT be switched).10. Make appropriate connections.Cautions:Where scraping to bare metal was required, and at the battery posts where wire ends and lugsmay be exposed, apply anti-corrosion compound.Insert the fuse only when installation is complete and ready to test.11. At the G3 position, neatly coil cable slack and attach securely.2.5 AntennaThe main transmitter antenna must be vehicle-mounted to provide a separation distance of 50 cm or morefrom all persons and the antenna gain must not exceed 5dBi (with a 1.6dB cable loss).2.5.1 Recommended tools and supplies• circle cutter, hole saw or socket punch for antenna• Mini-UHF Crimp tool
122 20130-003 G3 Installation Guide142.5.2 PlanningReferring to Figure 4, G3 commonly uses three separate antennas:• “T” - Main transceiver -Constraints are the limit of 50 cm (see section 2.5 above) and omni-directional factors• “R” - Auxiliary receiver –Constraints are the receiver spacing of at least 5/8 λ (wavelength) from transceiver antenna andomni-directional requirements• “G” - Global Positioning System (GPS)Constraints are TX spacing of at least 24-in/60.96 cm from all transmitting antennas and a clear viewof the sky.Figure 4 - Antenna spacingFor the optimum antenna spacing at the frequency you are using, consult System Engineering.For installation of ground-plane dependent antennas, the center of the metal surface used for mounting ispreferable for best omni-directional pattern. For ground-plane independent antennas, installation may beclose to the edges of the surface.Install the antennas in one of the following positions:• Most preferred for all antennas: centerline of roof. For transmitter antenna, it is the ONLY accept-able position.• Less preferred for receiver antenna: trunk lid, providing distance to transmitting antenna is respectedwhether lid is opened or closed.• Much less preferred, but permissible for receiver antenna: left or right rear fenders, just in back ofrear window• Least preferred, but permissible for receiver antenna: left or right front fenders, ahead of windshieldProximity to other vehicle-mounted antennas may cause mutual interference especially at higher fre-quencies.GMPE≥≥≥≥5/8λλλλ(UHF: 18"/46cm800MHz: 9"/23cm900MHz: 8”/21cm)RT50cm19.7in.≥≥≥≥24in.
122 20130-003 G3 Installation Guide152.5.3 Antenna Installation1. Route good quality 50-ohm coaxial cables (e.g. RG-223) from each of the selected antenna positionsto the position where the G3 unit is mounted.2. Terminate the end at each of the antenna positions with the appropriate connector for the antennaused and make the connection.3. At the G3 position, cut the three cables to length and terminate with the appropriate plug. For thetransceiver and the auxiliary cables, use a Mini-UHF crimp plug using an appropriate crimping tool.For the GPS, use a SMA connector.4. Positively identify the transceiver mini-UHF plug and connect to the left rear of G3.5. Positively identify the auxiliary receiver mini-UHF plug and connect to the front left of G3 to the RXposition.6. Connect the SMA connector to the GPS* position below the auxiliary connector position.7. Do not skip this last step, trust us; it is an important one. To complete the installation, tie-wrap to-gether the auxiliary and the GPS antenna cables at a point about two inches in front of the unit. It willbe much easier hereafter to correctly identify which mini-UHF plug goes where. You DO NOT wantto cross the auxiliary plug with the transceiver plug.2.6. Completing the physical Installation.To complete the physical installation and prior to testing G3:• Connect DC Power cable’s connector to G3’s until you hear a click as the two parts snap to-gether.• Re-check that all other connections are secure (antennas, PC, etc.)• Switch vehicle ignition ON.You are now ready to check for normal operation and to run the Radio Installation Software (WinRIS)program for testing or trouble-shooting.2.7. Checking out Normal operationCheck that the vehicle ignition is ON.1. Check for proper operation of the G3’s LEDs as per Table 1 on page 17.2. Using the WinRIS program and an in-line wattmeter, check forward & reverse power to confirmmain antenna installation (as per section 4).3. Using WinRIS, check the RF Data Link with a base station that can be heard (see section 4.3.3).If user application and its base station are available, test the installation by going through a normal se-quence of transmitting and receiving messages.

122 20130-003 G3 Installation Guide214.3.3 RF Data Link TestA link test between a mobile and a known base station can be done using the WinRIS "Address"and "Send" functions. The “Address” and “Device” fields, the “Send” button and the “Chat”message screen are used to send messages to specific mobile or base or to carry out RF test. Startby entering the address of the mobile (or base station) you wish to send a test message to or test:1- Specify the address:Addresses may be entered by typing directly in the “Address” field in two ways:- Numerically, the valid address range is 1-126.- As an “Alpha-Mapped-Nibble” (AMN) address, consisting of upper case letters in therange A-P. The valid address range is A to GN.- The base address is usually: 1.- The program may display one of the following messages on the status bar:- For Paragon products:“address is not in AMN or number format”- For mobile products:“address is not in the range A – GN”In either case, check that the address entered is within the acceptable range, is of a valid for-mat, and correctly typed.2- Enter the Device number for mobile (or base station).3- Press the Send button.The Chat window reports “Sent to xx mobile” (where xx is mobile name).If test is successful:Status line reports “Delivery confirmed.If test unsuccessful:Chat window reports “Waiting”,Then the Status line reports “Delivery Failed”.
