GeminiPD Installation Guide between these components and radio equipment. Try using existing holes in firewall and trunk wall and the channels above and below or beneath the doors, channels through doors and window columns that are convenient to run cables and wires. Whenever possible, install conduit in which to run the cables. 2. Installation 2.1 Planning the Installation 2.1.1 Overview To ensure trouble-free, efficient installation, start by inspecting the vehicle to determine the optimum position for GeminiPD and its antennas as well as the routing of all associated cabling and wiring. 2.2 Before starting installation, review all of the following warnings. 2.1.2 Location Often, 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 in the front cabin. 2.2.1 RF Radiation warning The Federal Communications Commission (FCC), with its action in the General Docket, 79-144, March 13, 1985, has adopted a safety standard for the human exposure to radio frequency electromagnetic energy emitted by FCC-regulated equipment. Only proper installation of the transceiver antenna of GeminiPD as summarized in section 2.5 will result in user exposure substantially below the FCC recommended limits. Be sure to place the GeminiPD unit in such a way that: • The LEDs can be seen (as an aid in troubleshooting) • Access to the antenna DE-9 connectors is possible without removing the unit • Sufficient air may flow around the unit to provide adequate cooling Qualified personnel must do all antenna installations. See paragraph 2.5.2 for recommended antenna positioning. GeminiPD is not fully waterproof, therefore it should be mounted sufficiently away from an opened trunk lid or opened tailgate, windows or doors to avoid exposure to rain and/or snow. It also minimizes the chance that material can be accidentally thrown on the unit or of someone bumping against it. Transmissions when persons or animals outside the vehicle are within two feet of the antenna may result in radio energy radiation burns or related injuries. 2.2.2 Interference with vehicular electronics 2.1.3 Cable Path Certain vehicle electronic devices may be prone to malfunction due to lack of protection from radio frequency energy present when transmitting. It includes, and is not limited to: Electronic fuel injection systems Electronic anti-skid braking systems Electronic cruise control systems Try to route the cables away from locations where they would be exposed to heat (exhaust pipes, mufflers, tailpipes, etc.), battery acid, sharp edges, mechanical damage or where they would be a nuisance to automobile mechanics, the driver or the passengers. Keep wiring away from automotive computer modules, other electronic modules and ignition circuits to help prevent interference 120 20110-144 Warnings GeminiPD Installation Guide containing the LP-gas container and its fittings. 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. If the installation vehicle contains such equipment, consult the dealer for the make of vehicle and enlist his aid in determining if such electronic circuits will perform normally when the radio is transmitting. 2.2.3 Secure mounting 2.3 For vehicle occupant(s) safety, mount GeminiPD securely so that the unit will not break loose in case of an accident or violent maneuvers. 2.3.1 Recommended tools and supplies • • • • 2.2.4 Explosive environments Operation of vehicular radio transmitters in explosive environments may be hazardous and conventional safety precautions must prevail. These include and are not limited to: Transmitting while fuelling the vehicle. Do not carry fuel containers in the same compartment as GeminiPD. Dynamite blasting caps may explode when transmitting radio operation takes place within 500 feet. Always obey the “Turn Off Two-Way Radios” signs posted at sites where dynamite is being 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 or from the vehicle. Check applicable local bylaws. • 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 frequency of the radio. 2.3.2 Physical mounting of GeminiPD Start by running all the cables (DC power, PC RS-232 as well as all antennas cabling) prior to mounting GeminiPD to assure the feasibility of the planned cable routing. Be sure to leave sufficient slack in each cable so the GeminiPD may be removed from the mounting bracket for servicing with the power applied and the antenna attached. GeminiPD is ready for installation. Cautions: • When drilling mounting holes, be careful to avoid damaging some vital part of the vehicle such as fuel tanks, transmission housing etc. Always check how far the mounting screws 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. 2.2.5 Installation in vehicles powered by liquefied gas. GeminiPD installations in vehicles powered by liquefied petroleum gas with the LP-gas container in the trunk or other sealed-off space within the interior of the vehicle must conform to the National Fire Protection Association Standard NFPA 58 which requires: Space containing radio equipment shall be isolated by a seal from the space 120 20110-144 Physical Unit GeminiPD Installation Guide • Do not overtighten selftapping screws. 1. Once you have found a suitable mounting position for GeminiPD, hold the unit and the unattached mounting bracket in the proposed mounting position and check that there is clearance behind the unit for the heatsink, cables, etc. Check that the position provides a large enough flat surface that the bracket will not be distorted when installed. 7. Drill any additional holes as required for routing all cables and fit holes with suitable grommets or bushings whenever required. 2.4 2.4.1 Electrical requirements GeminiPD is designed to operate from a 13.8Vdc nominal car battery (negative ground) and requires currents up to 15.0A. 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 rated 24/12 VDC converter to isolate the unit from the battery and protect it against excessive voltage. 0.2" 1.0" 2.5" 6.0" Figure 1 - Mounting plate and slot dimensions 2. 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. Warnings: Application of more than 16.3 VDC will damage GeminiPD and is not covered by the warranty. Always disconnect GeminiPD’s DC power lead before connecting a second battery, using power from another vehicle or power boosting (e.g. when “jump starting” the vehicle). 2.4.2 Routing of power cable 1. Start by disconnecting the vehicle’s battery unless specifically prohibited from doing so by the customer, vehicle manufacturer, agent or supplier. Note: In this event, exercise extreme caution throughout the installation and fit the fuse only when the installation is complete. Figure 2 - Bracket installation 5. Install the bracket without distorting. 6. Securely mount GeminiPD to the installed bracket using the four supplied 8x40 black machine screws. 120 20110-144 Electrical installation 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). GeminiPD Installation Guide 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 of the battery ground cable. The 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) If the negative cable is connected directly to the battery negative terminal, it should be fused in case of failure of the vehicle’s ground cable. Figure 3 - DC Power Connector 3. Place this connector at GeminiPD’s radio power input location. Do not connect at 13.8VDC B+ (Fused Red wire) GROUND (Blue wire) 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 GeminiPD turning ON and OFF dependent on the vehicle’s ignition key. • Connect to “Accessory” if you wish GeminiPD to be available when the engine is not running, but still dependent on the ignition key. • Connect to a user-supplied control switch. • In installations equipped with a “ChargeGuard”, connect to the controlled-side of the ChargeGuard (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 lugs may be exposed, apply anti-corrosion compound. Insert the fuse only when installation is complete and ready to test. SEAL (DO NOT REMOVE) IGNITION (Small red wire) this time. See paragraph 2.6, “Completing the physical installation”. 4. Carefully route both the B and the C wires to where the in-line fuse holder will be installed, usually as 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 unswitched 5. Insert the negative (blue) lead into one of the appropriate connector lug and crimp solidly to force the metal contacts onto the wires. 120 20110-144 11. At the GeminiPD position, neatly coil cable slack and attach securely. GeminiPD Installation Guide 2.5 Antenna MPE To meet the FCC’s RF Exposure Guidelines, the main transmitter antenna must be vehiclemounted to provide a separation distance of 50 cm or more from all persons and the antenna gain must not exceed 5dB to satisfy RF exposure requirements. 50cm 19.7in. ≥24in. 2.5.1 Recommended tools and supplies • • • • ≥5/8λ λ (UHF: 18"/46cm 800MHz: 9"/23cm) circle cutter hole saw or socket punch for antenna Mini-UHF Crimp tool Figure 4 - Antenna spacing 2.5.2 Planning Install the antennas in one of the following positions: - Most preferred for all antennas: centerline of roof. For transmitter antenna, it is the ONLY acceptable position. - Less preferred for receiver antenna: trunk lid, providing distance to transmitting antenna is respected whether lid is opened or closed. - Much less preferred, but permissible for receiver antenna: left or right rear fenders, just in back of rear window - Least preferred, but permissible for receiver antenna: left or right front fenders, ahead of windshield Note: Proximity to other vehicle-mounted antennas may cause mutual interference especially at higher frequencies. Referring to Figure 4, GeminiPD commonly uses three separate antennas: • “T” - Main transceiver Constraints are Maximum Permissive Exposure (“MPE” on the drawing) limits of 50 cm (as per 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 and omni-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 view of the sky. For 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 is preferable for best omni-directional pattern. For ground-plane independent antennas, installation may be close to the edges of the surface. * The GeminiPD Lite model has no GPS. 120 20110-144 GeminiPD Installation Guide • 2.5.3 Antenna Installation Connect DC Power cable’s connector to GeminiPD’s until you hear a click as the two parts snap together. Re-check that all other connections are secure (antennas, PC, etc.) Switch vehicle ignition ON. 1. Route good quality 50-ohm coaxial cables (e.g. RG-223) from each of the selected antenna positions to the position where the GeminiPD unit is mounted. • 2. Terminate the end at each of the antenna positions with the appropriate connector for the antenna used and make the connection. You are now ready to check for normal operation and to run the Radio Installation Software (WinRIS) program for testing or trouble-shooting. • 3. At the GeminiPD position, cut the three cables to length and terminate with the appropriate plug. For the transceiver and the auxiliary cables, use a Mini-UHF crimp plug using an appropriate crimping tool. For the GPS, use a SMA connector. 2.7. Checking out Normal operation Check that the vehicle ignition is ON. 1. Check for proper operation of the GeminiPD’s LEDs as per Table 1 in section 3.1 4. Positively identify the transceiver miniUHF plug and connect to the left rear of GeminiPD. 2. Using the WinRIS program (described in section 4) and an in-line wattmeter, check forward & reverse power to confirm main antenna installation. 5. Positively identify the auxiliary receiver mini-UHF plug and connect to the front left of GeminiPD to the RX position. 3. Using the WinRIS, check the RF link with a base station that can be heard by using the WinRIS “Ping” feature (see paragraph 4.4.4.4). 6. Connect the SMA connector to the GPS* position below the auxiliary connector position. or 7. Do not skip this last step, trust us; it is an important one. To complete the installation, tie-wrap together the auxiliary and the GPS* antenna cables at a point about two inches in front of the unit. It will be much easier hereafter to correctly identify which mini-UHF plug goes where. You DO NOT want to cross the auxiliary plug with the transceiver plug. If user application and its base station are available, test the installation by going through a normal sequence of transmitting and receiving messages. * The GeminiPD Lite model has no GPS. 2.6.

It may also tolerate user pull-up to external +12 VDC (car battery), but an isolated dry contact is preferred due to the risk of noise-related false alarms caused by the vehicle’s electrical system. A +3 to +12 V signal at this pin will send a DMP “x” (On) message to the base. An open or ground signal will send a DMP “y” (Off) message. Messages are only sent when a signal transition occurs. See Appendix “A” on page 24 for further details. 120 20110-144 10 Term Alternates Signal level OFF asserted, spacing dropped, marking +3 to +15 V -3 to -15 V GeminiPD Installation Guide 4.2 4. WinRIS program The Windows Radio Installation (WinRIS) program is used to: • • • Software Connect a suitable 9-conductor straight RS-232 cable, between the unit’s front-mounted PC/Setup port and the RS-232 port of the PC or portable computer that will be running Gemini.exe program. PD Check and troubleshoot Gemini . Save an existing configuration. Upload files for field-configuring units (Requires intervention with technical support). GeminiPD’s WinRIS program is available on diskette, Dataradio p/n 980 03392-00n. Refer to the WinRIS Readme.txt file for details on how to set MS-Windows environment, connect, install and run this program. To run the program, you will need: A PC or portable computer running a 32-bit MSWindows application: Win ME Win2000 Win NT Win 9x Note: WinRIS does not operate under: Win CE (embedded in PocketPC) 16-bit Windows 3.x In summary, before starting the WinRIS when running MS-Windows, click on “Start”, then on "Run". Type the relevant path and variables on the command line (or select by browsing) leading to: WinRIS.EXE COM[x], [speed],8,n,1 A hard disk. An available COM port. A serial mouse, with its own driver installed is strongly recommend however most actions can also be done using keyboard command 4.1 (where x is the PC COM port to be used) Of course, the executable command may be used alone without any variable added. Click on “OK”. It is also possible to create a PC desktop shortcut icon for WinRIS: • Start by right clicking anywhere on the desktop, • Select New, • Select Shortcut and type the path as detailed above directly on the command line (with or without variables). • Click Next, • Type in an applicable name for the shortcut icon, • Click Next • Select an icon (your choice) and • Click on Finish. Operation This support program can be run in MSWindows © mode. DO NOT have more than one copy of this program loaded at any given time in separate windows. Doing so creates COM port sharing conflicts and failure to run the program alone results in unexpected transmissions. Only left mouse button operation is supported. Any command or selection shown in gray is either unavailable or is awaiting another action before activating. Command line settings override the environment variable, if any. Help in the program is available at all points by pressing the F1 key. If a subject is highlighted, the help displayed will be context sensitive. 120 20110-144 To connect and start WinRIS 11 GeminiPD Installation Guide Figure 6 - WinRIS window 4.3 Window This program uses one main display screen only.

Banner Field This field displays a string made up of the serial number of the connected unit followed by the firmwares used and their version number. Format is: [serial number]:firmware 1 name, its version #, firmware 2 name, its version #. Warning: Do not make any changes to these files. Any changes made to the configurations MUST be done at factory or by Dataradio system engineering. 120 20110-144 “Put From” button The serial number portion uniquely identifies the unit. It is a variable length, maximum eightcharacter alphabetic string assigned at the time of manufacture. It is identical to the serial number printed on the label of the unit. This number cannot be changed and is used as part of the onair protocol. 14 GeminiPD Installation Guide GeminiPD's firmwares resides in flash EPROM and are designed to allow field upgrades. The Dataradio supplied password algorithm is designed to thwart the casual observer only. It provides a limited form of data privacy. Therefore, if your security requirements are high, Dataradio urges you to use external encryption technology (such as Data Encryption Standard (DES)) in the Host and Mobiles computers. When contacting your supplier, give the full banner string and the version of the WinRIS used. You will find the version number by selecting the “Help” menu option, then “About WinRIS” command or pressing the “About” button on the Toolbar. 4.4.5 Test Functions The “Banner” field is blank prior to doing a "Get", "Get As" or "Put From". The following WinRIS functions and buttons are used to carry out testing or trouble-shooting on a connected unit: 4.4.4.2 • DSR signal is High indicator • CTS signal is High indicator • Channels select • Show All Channel Frequencies • RSSI Indicator • TXON (Modulated) Comments 1- Type comments directly in the “Comments” field. These can be text up to 24 characters. Use this field to enter user-convenient description(s) (customer name, location, etc…). 2- Press the button “Put Comments” to make the entry permanent. This field may be left blank. On subsequent “Get”, “Get As” or “Put From”, this field displays entered comments. If no comment was entered, the field will remain blank. • TXON (Unmodulated) • Ping Address and Ping button 4.4.4.3 4.4.5.1 Password The password feature is useful where two (or more) fleets share the same radio channel. Mobiles without the proper password would still receive the message but the contents would not be intelligible. DSR signal is High indicator The “Data Set Ready” (DSR) indicator light, located on the button bar (leftmost), is an RS232 protocol port indication. When lit, it indicates proper connection and that the value is High. The DMP protocol used requires that DSR be normally asserted. 1- Type your password directly in the “Password” field. It is a string of 32 hexadecimal characters (exactly). 2- Press the button “Put Password” to make the entry permanent. This field may be left blank. On subsequent “Get”, “Get As” or “Put From”, this field will require that the correct password be entered. If none was entered, the field will remain blank. Password information is NOT retrieved and saved to a file, along with the configuration. Clearing a Password is done by entering 32 zeros. 120 20110-144 15 GeminiPD Installation Guide 4.4.5.2 4.4.5.4 CTS signal is High indicator The Radio Signal Strength Indicator (RSSI) bar graph usually displays in twin-columns the relative strength (in dBm) of an incoming RF signal on the selected channel. The left column indication, labeled "I", shows the transceiver RX signal (rear mini-UHF connector). The right column indication, labeled "II", shows the auxiliary RX signal (front mini-UHF connector). Meter precision is usually better than 3 dBm. The “Clear-to-Send” (CTS) indicator light, located on the button bar (second indicator from the left), is an RS-232 protocol port indication. When lit, it indicates proper connection and that the value is High. The DMP protocol used requires that CTS be normally asserted. 4.4.5.3 RSSI & Power Out Indicators Channel Selection Select the radio channel on which you wish to send a test transmission by clicking the relevant available option button. The program automatically detects which of sixteen channels are present on the connected unit. For each factory-set channel available, the relevant round option button and channel number is enabled (black). For each unavailable channel, the round option button and channel number appears disabled (grayed-out). Only one channel at a time may be selected. This indicator functions as a single column "Power" (Watt) meter when using either of the test functions: "TXON (Modulated)" or "TXON (Unmodulated)" with a range of 0 to 60 watts. Precision is usually better than +/-3 watts. Note: This internal wattmeter is designed for use as reference only and is not a substitute for a quality external precision measuring instrument. Pressing the “Show All Channel Frequencies” button opens a sub-window (see Figure 8) listing in tabular form the radio transmitting and receiving frequencies programmed for each available channel(s). 4.4.5.5 TXON tests TXON test functions are selected by choosing “Test” from the file menu, then “Modulated” or “UnModulated” command or by pressing the relevant button on the Toolbar. To exit this sub-window, press the upper right system box. 4.4.5.5.1 Unmodulated Carrier Unmodulated carrier gives a clear carrier and is frequently used for checking: • Frequency error • Forward and reverse power Press the TXON (Unmodulated) button to transmit an unmodulated 20-seconds test signal on the channel selected or until the button is pressed again. The functions of all the other buttons are inoperative during test transmissions. Power check: 1- Connect an in-line power meter between the radio and the antenna. 2- Measure the forward (nominal 40W for UHF model and 35W for 800MHz model) and reflected power levels by powering TX ON Figure 8 - Show All Channel Frequency 120 20110-144 16 GeminiPD Installation Guide base station by sending a short transmission query and receiving a confirming response.

Trouble-Shooting and Testing 5.3 About three minutes after ignition is turned-on, the PWR LED on the GeminiPD front panel should flash in amber color at the rate of one pulse per second.1 This indicates that the GPS has acquired the sky position of a sufficient number of satellites to arrive at a ground position solution. The checks described below should be done at annual intervals or whenever deterioration in performance is noted. 5.1 • • • • Equipment Required If the GPS has a good view of the sky and still has not generated any position solution within three minutes (it may take up to 10 minutes or more if the sky view is partially blocked.), the following trouble-shooting procedures should be undertaken to isolate the fault: 13.8 VDC (nominal) car battery, or 13.8 VDC/20A regulated power supply (In the 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 to connect GeminiPD to the service monitor. 5.2 GPS Test 1) Disconnect the GPS antenna cable connector from the Gemini radio and check for + 5 VDC on the center pin of the GPS antenna connector on the radio using a Digital voltmeter (DVM). If the voltage is present, do not reconnect the cable and proceed to step 2. Basic Tests Recommended checks: 1. Transmit and Reverse power output 2. Carrier frequency error 3. Frequency deviation 4. Receivers RSSI Check 5. Link test between Gemini and the base station. 6. GPS test (not required on GeminiPD Lite model). 2) With the DVM, measure resistance between the shell and the center conductor of the GPS cable, resistance should be between 100 and 300 Ohms, if it measures open or short circuit the GPS antenna is either a passive antenna which is the WRONG type, or a defective active antenna, replace with a known good active antenna. Refer to Table 5 for checks 1 to 5. Important note: Before proceeding make sure that the service monitor has been calibrated recently and has warmed up for at least the time specified by its manufacturer. 3) Connect the new antenna to Gemini and wait about three minutes for the POSITION ACQUIRED indicator to start flashing on GeminiPD, if not, the Gemini radio or its GPS receiver is defective Some reported frequency and deviation problems have actually been erroneous indications from service monitors that have not adequately warmed up. This is particularly likely when field service is done during winter months Refer to the WinRIS section for function details 120 20110-144 19 Lit green and flashing amber for the 800MHz model under 2% duty cycle limit.

Overview The DTE Port Interface pin 9 (AUX) on DEV-2 is used for the “Officer Requires Assistance” alarm function. Intended Audience This document is designed for use by System Integrators. Physical Connection This auxiliary input may be activated by (normally open) dry contact pull-up to the port’s DSR output. It can also tolerate user pull-up to external +12 VDC (car battery), but an isolated dry contact is preferred due to the risk of noise-related false alarms caused by the vehicle’s electrical system. A +3 to +12 V signal at this pin will send a DMP “x” (On) message to the base. An open or ground signal will send a DMP “y” (Off) message. Messages are only sent when a signal transition occurs (debounced for approximately 100 ms). Operation When using GeminiPD or GeminiPD Lite products, activating the “Officer Requires Assistance” alarm input starts emergency communications: • The modem creates DMP “x” or “y” messages. • Any other pending message(s) will be failed to avoid delaying the alarm message on account of lower priority traffic and to remove non-emergency messages from duty-cycle management (if applicable). In the case of a “q” message, a D-NAK* will be immediately returned. • Base and Channel hunt will take place for the usual number of retries per base (according to configuration) but will cycle forever until D-ACKed* or Reset*. • Lack of base DBA synch will not prevent transmission to maximize the chance that a base gets the alarm signal. DBA “Freewheel” mode will be forced until the alarm is acknowledged. * For details on DMP terms, refer to DMP 1.5 manual, version 4.0 120 20110-144 24 GeminiPD Installation Guide
