Refer to Figure 1-4. • External Speaker Jack • J104 provides repeater audio output to an external speaker. The local volume control adjusts the volume level of this speaker. • Speaker/Microphone Jacks • Indicates that the CW Identification is being transmitted on the lowest-frequency repeater. The CWID is a continuous-wave (CW) transmission of the station call letters in Morse Code to satisfy the station identification requirement. The CWID is programmed into the repeater memory. This indicator also is used when an alarm is transmitted with Morse code. A D Level Test Point J100 provides audio/data level output for test level checks. • CWID Indicator Local On/Off/Volume Control R236 provides control of the receive audio output to J101 and J104. Turning this control clockwise past the detent applies voltage to the local audio amplifier. • Power Indicator CR501 indicates the +5V supply is at normal level and applied to the IAC. CR524 indicates -5V supply is at normal level and applied to the IAC. CR523 indicates the +15V accessory supply is at normal level. CR525 indicates that the +15V supply is at normal level and applied to the IAC. J102 provides audio input from a microphone. J101 provides the receive audio to the microphone. • Power Supply On/Off Switch • Hang Indicator Indicates that the hang word is being transmitted by the repeater. This word is transmitted on calls in which the channel is held for the duration of the call and not just for the duration of the transmission. The hang word tells the mobiles to stay on the same channel and not re-access the system when responding to a call. Ground J103 is connected to ground for test equipment when monitoring test point J100. 1.12.3 INTERFACE ALARM CARD (IAC) Refer to Figure 1-4. • • Voltage Test Output J502 provides a +15V test point on the IAC. • Not used in the LTR repeater.

Xmit Indicator This indicates that the repeater transmitter is keyed by the logic. 1-7 May 2000 Part No. 001-2008-204 INTRODUCTION AND OPERATION 1.12.4 POWER SUPPLY code and Home repeater number are the "address" of the mobiles in the system. Therefore, up to 1250 separate addresses can be assigned in a 5-repeater system and up to 5000 can be assigned in a 20-repeater system. An ID code may be assigned to an individual mobile or a group of mobiles as required. The 2000 Series Repeater Power Supply is a quad output 800W supply with power factor correction. A battery back-up module, PN 023-2000-830, can be added to the power supply to provide automatic battery revert in the event of AC power failure (see Section 2.5) The Battery Back-Up module charges the batteries when AC is present at the power supply (see Section 2.4 and 8.5). 1.13.3 INTER-REPEATER DATA COMMUNICATION Data communication between VIKING VX and LTR repeaters at a site is via a high-speed data bus. This bus cable is installed in a daisy-chain manner between repeaters. If both VIKING VX and LTR repeaters are located at a site, 20 repeaters can be interconnected. Refer to Section 1.9 for information on connecting the data bus. 1.13 REPEATER INFORMATION 1.13.1 INTRODUCTION NOTE: The VIKING VX does not require a separate LTR logic drawer. The repeater model used in an LTR system is determined by frequency range. 800 MHz systems use the VIKING VX (-232/-234) or LTR 8000s, UHF use 1010s, and VHF use 1100s. Repeaters operate on a single frequency (one repeater is required for each channel). The MPC in each repeater performs all control and signaling functions on that channel. Information is exchanged between repeaters via a high-speed data bus (modular cable). No system controller is required. 1.13.4 MOBILE TRANSCEIVERS Optional accessories, such as the Telephone Interconnect Card (TIC) can be installed in the repeater and the ID Validator drawer can be installed in the repeater rack. Refer to Johnson LTR ID Validator Manual, Part No. 001-4408-501 and Johnson Telephone Interconnect Card Manual, Part No. 004-2000370 for detailed information. A single-line serial data bus interconnects the logic units of all the LTR repeaters at the site. The first repeater powered on generates the synchronization pulse that is used by all other repeaters to determine their time slot on the data bus. If all repeaters are powered on at the same time, the lowest numbered repeater generates the synchronization pulse. There are 21 slots with 1-20 used for repeater reporting and 21 used by the ID Validator (see Section 1.14.3). The time slot used by a repeater is determined by the number assigned to that repeater by the programming in the MPC. Repeater 1 uses time slot 1, repeater 5 uses time slot 5, and so on. The data rate on the repeater data bus is 18,750 bits per second. The mobile and handheld transceivers used in an LTR system must be compatible with the type of signaling in use and also the frequency range. 1.14 REPEATER DATA BUS SIGNALING 1.14.1 GENERAL 1.13.2 HOME REPEATERS All mobiles have one of the site repeaters assigned as its "Home" repeater. This is the repeater from which it receives most of its control information. When a mobile is not placing or receiving a call, it is always monitoring its Home repeater to determine which channel is free and if it is being called by another mobile. In its time slot, each repeater places information on the data bus indicating its status. If a repeater is not busy, only start bits appear in its slot. If a repeater is busy, it places in its slot the Home repeater and ID code of the mobile receiving the call on that repeater. If a repeater number is unassigned, nothing appears in that time slot. The Home repeater is always used to make a call unless it is busy. When the Home repeater is busy, any other repeater in the site may then be used. Up to 250 ID codes are assigned to each repeater. An ID May 2000 Part No. 001-2008-204 1-8 INTRODUCTION AND OPERATION 1.14.2 MOBILE DATA MESSAGE ORDER 1.14.3 ID VALIDATOR OPERATION Each repeater monitors all the time slots on the repeater data bus. If it detects its number in another time slot, it begins transmitting an additional data message to its mobiles. This message tells mobiles programmed to detect that ID code to go to that repeater to receive a call. This additional message continues for as long as the mobile is transmitting on the other repeater. If the ID Validator is used, it is programmed with the status of up to all 5000 home repeater/ID code combinations possible with a 20-channel system. Each combination is programmed as either valid or invalid. Information in the twenty time slots on the repeater data bus is monitored. If an invalid home repeater/ID code combination is detected, the ID Validator places in time slot 21 the number of the repeater being used by the invalid mobile and also the ID code. When a repeater detects its number in slot 21, it transmits the turn-off code (31) to the mobile receiving the call. That mobile then squelches and resumes monitoring its home channel. This effectively disables the invalid mobile because it cannot talk to anyone. When the turn-off code is sent, the repeater places "21" in the repeater position of its time slot to indicate to the ID validator that turn-off has occurred. The sequence of data messages transmitted on a home repeater is as follows: Every third message is to the mobile currently receiving a call on that repeater. Then alternating between these messages are messages to its mobiles that have been trunked to other repeaters. For example, assume that five different mobiles on a five-repeater system are making calls. If all have Repeater 1 as their home channel (not very likely in actual practice), the data message order on Repeater 1 is as follows: 1 2 3 1 4 5 1 2 3 and so on. 1-9 May 2000 Part No. 001-2008-204 INTRODUCTION AND OPERATION May 2000 Part No. 001-2008-204 1-10 INTRODUCTION AND OPERATION SPECIFICATIONS GENERAL1 Frequency Range Dimensions AC Voltage/Frequency AC Current (Low Power) AC Current (High Power) AC Input Power (Low Power) AC Input Power (High Power) DC Current at 26.5V DC (Low Power) DC Current at 26.5V DC (High Power) Number of Channels Channel Spacing Channel Resolution Temperature Range Duty Cycle FCC Type Acceptance FCC Compliance 806-824 MHz Receive, 851-869 MHz Transmit 9.125" H x 17" W x 20.9" D 100-240V AC/50-60 Hz 0.40A (Standby), 1.7A (25W), 2.8A (75W) 0.40A (Standby), 3.8A (75W), 5.8A (175W) 45W (Standby), 199W (25W), 328W (75W) 45W (Standby), 445W (75W), 680W (175W) 5.2A (25W), 9.8A (75W) 11.5A (75W), 19.5A (175W) 1 (Synthesized, programmable) 25 kHz 12.5 kHz -30°C to +60°C (-22°F to +140°F) Continuous ATH2422008, ATH2422008-1 Parts 15, 90 RECEIVER 12 dB SINAD 20 dB Quieting Signal Displacement Bandwidth Adjacent Channel Rejection Intermodulation Rejection Spurious & Image Rejection Audio Squelch Sensitivity Audio Response Audio Distortion Local Audio Power Audio Sensitivity Hum & Noise Ratio Frequency Spread Frequency Stability 0.35 µV 0.50 µV ±2 kHz -85 dB -80 dB -90 dB 12 dB SINAD +1/-3 dB TIA Less than 3% at 0.5W/16 ohms 0.5W/16 ohms ±1.5 kHz -45 dB 6 MHz ±1 PPM -30°C to +60°C (-22°F to +140°F) TRANSMITTER RF Power Out (Low Power) RF Power Out (High Power) Spurious Emissions Harmonic Emissions Audio Deviation LTR Data Deviation CWID Deviation Repeat Deviation Audio Response Audio Distortion Hum & Noise (TIA) Frequency Spread Frequency Stability Emission Designators 75W (Default setting), 25W (Variable Set Point) 175W (Default setting), 75W (Variable Set Point) -90 dBc -90 dBc ±3.5 kHz ±1 kHz ±2 kHz ±1.5 kHz +1/-3 dB TIA Less than 2% -45 dB 6 MHz ±1 PPM -30°C to +60°C (-22°F to +140°F) 14K0F3E, 16K0F3E, 14K0F3D, 16K0F3D, 14K0F1D, 16K0F1D 1.

The cabinets and filters should be placed on a maintainence schedule. Information in this section tells how to set up the repeater for operation in an LTR system. It is assumed that the repeater has been previously aligned at the factory or as described in the alignment procedure in Section 7. When the repeaters are installed in an environment that contains small airborn particles, e.g. grain dust or salt fog, the repeater cabinets need to be sealed. A heat exchanger, i.e. air conditioner, is then required to cool the cabinets. The air conditioners must be suited for the environment. Each low power repeater (75W) requires >1200 BTU/hr dissipation to maintain exterior cabinet temperature. Each high power (160W or 175W) requires >2100 BTU/hr dissipation to maintaim exterior cabinet temperature. Even though each repeater is thoroughly aligned and tested at the factory, it is good practice to check performance before it is placed in service. This ensures that no damage occurred during shipment and that the repeater is otherwise operating properly. Performance testing is described in Sections 7.1, 7.2, 7.3 and 7.4. 2.1.1 SITE PREPARATION AND ANTENNA INSTALLATION Site preparation and antenna installation are not within the scope of this manual. Basic installation requirements are discussed in the "Dealer Guide To Site Preparation", Part No. 004-8000-100. Factory installation is also available. Contact your Johnson representative for more information. 2.3 VENTILATION The RF modules and the power supply are equipped with fans, controlled by thermostats, that force air through the equipment for cooling. The air flow is from the front to the back of the equipment. This permits the Repeaters to be stacked or rack mounted (see Figure 2-4). There are a few considerations when installing Repeaters to provide adequate air circulation. 2.2 ENVIRONMENT The following conditions should be considered when selecting a site for the Repeater. 1. The Repeaters should be mounted with a minimum of 6 inches clearance between the front or back of the cabinet for air flow. The power supply requires a minimum of 18 inches at the back of the Repeater for removal. Operating Temperature. -30°C to +60°C (-22°F to +140°F). Humidity. NOTE: Repeaters should not touch. Leave a minimum of one empty screw hole (approximately 1/2") between repeaters vertically especially for bottom ventilation slots in high power repeaters. Less than 95% relative humidity at 50°C. Air Quality. For equipment operating in a controlled environment with the Repeaters rack mounted, the airborne particles must not exceed 30 µg/m3. For equipment operating in an uncontrolled environment with the Repeaters rack mounted, the airborne particles must not exceed 100 µg/m3. 2-1 • Cabinet enclosures must provide air vents for adequate air circulation. • Temperature and humidity must be considered when several Repeaters are installed at a site. This might require air conditioning the site. May 2000 Part No. 001-2008-204 INSTALLATION 2.4 AC POWER B- The AC power source to the Johnson VIKING VX Repeater can be 120V AC or 240V AC. Nothing need be done to the power supply for 240V AC operation. However, a 240V AC outlet requires that the 120V AC power plug be replaced. A locking AC power cord is provided for the supply. B+ TEMP REVERSE BATTERY CHARGER ACTIVE SWITCH CHARGER ON EARTH GROUND BATTERY FAULT LINE The 120V AC cord is a standard 3-wire grounded cord used with a standard AC wall outlet. The outlet must be capable of supplying a maximum of 328W (232) or 680W (-234). With the nominal 120V AC input, the source must supply 3A for each 75W repeater or 6A for each 175W repeater and should be protected by a circuit breaker. It is recommended that all of the repeaters in a rack should not be on the same breaker in order to provide one operational repeater in the event a breaker trips. An AC surge protector is recommended for all equipment. NEUTRAL Figure 2-1 BATTERY BACKUP CONNECTOR TEMP Each Repeater requires an outlet, so for a 5-channel system, a minimum of 5 outlets is required. An additional three outlets should be added for test equipment. The outlets must be within 3 feet of each Repeater cabinet. Future system expansion should be considered when electrical work is being planned for the initial system. WHT GND BLK NEGATIVE BATTERY TERMINAL The VIKING VX Repeater power supply can be equipped with an optional 24V DC back-up in the event of AC power failure. Since the transmitter will remain on full power, if desired, the DC power source must have a current capability of about 15A per 75W repeater (25A per 175W repeater) or 75A for 5-75W repeaters (125A for 5-175W repeaters). The multicoupler requires another 0.5A for a total system requirement at 24V DC of 75.5A for 75W repeaters (125.5A for 175W repeaters). Figure 2-2 TEMPERATURE SENSOR CABLE 2.6 800W POWER SUPPLY The power supply has four voltage output levels (see Table 2-1). Each voltage is set to ±1% at +25°C (+77°F). The output of this supply is capable or running any 2000 series repeater. 2.5 BATTERY BACKUP Each output is overload protected such that the power supply current limits and automatically resets when the overload is removed (see Table 2-1). If the power supply is equipped with battery backup, screw lugs are provided on the front of the power supply for battery connections (see Figure 2-1). A switch is provided for charging the battery or can be off if a separate battery charger is used. A battery temperature sensor connection is also provided. The temperature sensor cable is shown in Figure 2-2. LED indicators are provided to show Reverse Battery connection, Charger On/Off and Battery Fault. May 2000 Part No. 001-2008-204 Each output is over voltage protected such that the power supply shuts down when an over voltage condition exists, usually when a component in the supply has failed (see Table 2-2). The power supply must be manually reset by toggling the Enable Line or removing AC power for more than 10 seconds. 2-2 INSTALLATION POWER HARNESS BACKPLANE J2 +26.5V GROUND TO RFIB +15V J2 AC FAIL IN POWER SWITCH 10 11 12 THERMAL SENSOR 4 N/C +15V N/C 10 N/C 11 +5V 12 -5V TO REPEATER BACKPLANE Figure 2-3 POWER CABLE CONNECTOR AND SCHEMATIC 2.6.1 AC INPUT REQUIREMENTS Table 2-1 OUTPUT VOLTAGES Voltage Current Wattage +26.5V 22A 583W +15V 5A 75W +5.2V 5A 26W -5V 1A 5W AC Input Voltage: Line Frequency: AC In-rush: Overall Efficiency: Lightning protection: Power Factor: Brown Out Voltage: Temperature Power factor correction per IEC555.

If a battery back-up is installed, the batteries take over when the AC input voltage falls below 80V AC (dependant on power output). The AC input connector is an IEC connector equipped with a locking mechanism. 2-3 May 2000 Part No. 001-2008-204 INSTALLATION Secondary protection (other than grounding) provides the equipment protection against line transients that result from lightning. There are two types of secondary protection, RF and Telephone Line. Use the same wire sizes as specified for coaxial cables for any ground connections required by the secondary protectors. The operating temperature range is -30°C to +60°C (-22°F to +140°F), i.e. the same as the repeater. The fan is thermostatically controlled by the internal temperature. When the internal heatsink temperature reaches +45°C (113°F) the fan turns on. When the heatsink temperature drops below +35°C (95°F) the fan turns off. If the internal heatsink temperature reaches +90°C (+194°F) the power supply turns off until the heatsink temperature drops below +85°C (+185°F). The over-temperature shutdown and restart are automatic. • RF An RF protector keeps any lightning strike to the antenna feed line or tower from damaging the Repeaters. Install this protection in-line with the combiner and antenna feed line. 2.7 GROUNDING CAUTION RF protectors are selected by calculating the maximum instantaneous voltage at the output of the combiner. Do this by using the following equation. PROPER SITE GROUNDING AND LIGHTNING PROTECTION ARE VERY IMPORTANT TO PREVENT PERMANENT DAMAGE TO THE REPEATER. Vp = 1.414 ( X ) ( P ( 50 ) ) where: VP = Voltage at the output of the combiner. P = repeater output in watts As in any fixed radio installation, measures should be taken to reduce the possibility of lightning damage to the Viking VX equipment. Proper grounding eliminates shock hazard, protects against electromagnetic interference (EMI) and lightning. X= 1.05 1.09 1.13 1.17 1.20 1.30 Ground each piece of equipment separately. Do not ground one piece of equipment by connecting it to another grounded piece of equipment. A good DC ground must be found or created at the site. Rooftop site grounds can be researched through the building management or architects. Tower site grounds must be made with grounding rods. The many techniques for providing adequate grounds for towers and poles and for installing building ground bus lines are beyond the scope of this manual. Refer to National Electrical Code article 250 "Grounding Techniques," article 800 "Communications Systems" and follow local codes. for VSWR= 1.10 : 1 1.20 : 1 1.30 : 1 1.40 : 1 1.50 : 1 1.86 : 1 Example: Repeater power output of 60W with a VSWR of 1.3 : 1 (for this VSWR, X = 1.13): Vp = 1.414 ( 1.13 ) ( 60 ( 50 ) ) Vp = 1.59782 ( 60 ( 50 ) ) Vp = 1.59782 ( 54.772256 ) VP = 87.52V • Telephone Line The ground bus should be routed to the floor area within 5 feet of the system with a runner of 6 AWG or larger solid copper wire or 8 AWG stranded copper wire. There are four types of protection suppressors for telephone lines; Gas Tube, Silicon Avalanche Diode, Metal Oxide Varistor and Hybrid. The outer conductor of each transmission line at the point where it enters the building should be grounded using 6 AWG or larger solid copper wire or 8 AWG stranded wire. The hybrid protector is ideal for Transcrypt Internation, Inc. equipment, and is strongly recommended. A hybrid suppressor combines several forms of protection not available in just one type of device. May 2000 Part No. 001-2008-204 2-4 INSTALLATION For example, a high-speed diode reacts first, clamping a voltage strike within 10 ns, a heavy duty heat coil reacts next to reduce the remainder of the current surge, and a high-powered three-element gas tube fires, grounding Tip and Ring. 2.7.1 PROTECTION GUIDELINES Follow these guidelines for grounding and lightning protection. Each Repeater installation site is different; all of these may not apply. • Ensure that ground connections make good metalto-metal contact (grounding rod, grounding tray, metal conduit) using #6 gauge solid wire or braided wire straps. • With surge protectors, ensure that ground wires go directly to ground, and not through other equipment. • Run the ground wire for RF coax protectors directly to ground. • TX CO MB With coax protectors, ensure maximum instantaneous voltage does not exceed the rated voltage. • Do not run ground wires parallel to any other wiring (e.g. a ground wire parallel to a telephone line), except other ground wires. • Double check all equipment for good ground and that all connections are clean and secure.

When the Repeater arrives, ensure the crates remain upright, especially if storing the crates temporarily. When unpacking the Repeater, check for any visible damage or problems caused by shipping. If there is obvious damage from shipping mishaps, file claims with the carrier. If there appears to be any damage caused before shipping, file a claim with Transcrypt Internation, Inc.

The BNC Adapter Module is installed on the back of the VIKING VX repeater cabinet (see Figure 2-13 and Figure 2-14). If everything appears undamaged, remove the Repeater equipment from the crate, using normal precautions for unpacking. NOTE: Do not discard the packing materials. If you must return an item; use the same packing materials and methods (including static protective bags for circuit cards) to repack the equipment. You are responsible for proper repacking. Transcrypt Internation, Inc. cannot be responsible for damage to equipment caused by negligence. Systems constructed only with LTR VIKING VX repeaters that have Version 202 or later HSDB software ( see Section 4.5.4) and do not use VNC cards can be connected directly to the HSDB from the RJ-11 jack on the back of the repeater. NOTE: Repeaters should not touch, leave a minimum of one empty screw hole (approximately 1/2") between repeaters vertically especially for bottom ventilation slots in high power repeaters. 2.9.1 MPC DATA BUS SWITCH SETTINGS NOTE: Each repeater should be grounded separately by connecting a ground bus from the ground lug on the back side of the RF module to the ground bar on the rack (see Figure 2-8). Switch settings on the MPC for the two types of installations require S2 and S3 sections to be switched as indicated in Figures 2-10 through 2-14. 2.9.2 MPC DATA BUS JUMPER SETTINGS 2.9 REPEATER DATA BUS INSTALLATION Refer to Figure 2-6 for crystal selection and HSDB Code selections jumper placement.

Although each transmitter and receiver could be connected to a separate antenna, this is usually not done because of the large number of antennas required by a multiple repeater installation. Therefore, an antenna combining system is usually used. An example of a combining system for a five-channel system is shown in Figure 2-5. The amount of power loss introduced by a combiner depends on the type of combiner used. If it has a loss of 3 dB, power output to the antenna is reduced by half.

The MS-DOS Revision 2.0 or later operating system is needed to run the programs. The computer needs to have RS-232C capability, for example, the Serial Card in slot "COM1" or "COM2". The Johnson Summit QX Repeater Program on 3.5 inch disk, Part No. 023-9998-297, uses an IBM personal computer to program the EEPROM Memory in the Main Processor Card (MPC). To lessen the chance of programming errors and simplify operation, the program uses yes/no questions or toggles through the available responses. 3.1.3 COMPUTER DESCRIPTION The programming software is designed to run on an IBM PC or compatible computer that meet the following minimum requirements. The computer is connected directly from the serial card to the MPC. The interconnect cables used are shown in Figure 4-30. The DB-9 to 8-pin modular adapter is connected to the serial port of the computer and an interconnect cable connects the adapter to the MPC. NOTE: These connections are for the IBM computer and may differ from an IBM compatible. In which case, consult the manuals for your computer for serial card outputs and connections. 3.1.1 HOW TO USE THIS MANUAL • One 3.5" high density disk drive • 640K of memory • MS-DOS version 2.0 or higher • One serial port • Monochrome or color monitor and video card Although the program uses color to highlight certain areas on the screen, a monochrome (black and white) monitor or LCD laptop also provide satisfactory operation. Most video formats such as EGA and VGA are supported. A serial port is required to connect the repeater to the computer. This port is standard with most computers. This manual introduces the program and illustrates how to use the features. This manual is organized to easily find programming information with the Table of Contents, Index and Parameter Tables for the responses required for programming. The cables from the repeater to the computer are not included. With most computers, the adapter-tocomputer cable is a standard DB-25 M-F cable, PN 023-5800-017, (the male connector plugs into the adapter). If your computer requires a male connector, a male-to-male cable is also available, PN 023-5800016. The cable from the adapter to the repeater has a DB-9 to 8-pin connector (see Figure 4-30). Graphic reproductions of the screens are shown for reference. Adjacent to the screens are tables to provide the parameters, available responses and a brief description of the parameter. It is not the intent of this manual to teach computer operation, but to allow the user to become familiar with the available screens and the responses without having to be at the computer. 3.1.2 GETTING STARTED 3.1.4 EEPROM DATA STORAGE NOTE: Before starting you should already know how to start MS-DOS, format and make backup copies of disks, copy and delete files, and run programs. If you are unfamiliar with any of these actions, refer to the MS-DOS manual for your computer for more information (see Section 5). The data programmed into the MPC is stored by an EEPROM memory. Since this type of device is nonvolatile, data is stored indefinitely without the need for a constant power supply. A repeater can be removed from the site or even stored indefinitely with- 3-1 May 2000 Part No. 001-2008-204 SOFTWARE 3.1.6 COLOR OR MONOCHROME OPERATION out affecting programming. Since EEPROM memory is also reprogrammable, a new device is not needed if programming is changed. The programming software utilizes color for a color monitor and video card. However, with LCDtype displays, this may make some information hard to read because the contrast is poor. To improve contrast, a monochrome mode can be selected in the display mode from Utilities heading. 3.1.5 COMMAND LINE OPTIONS • Help To show all options available from the command line type: /h or /?. Either ’/’ or ’-’ can be used. For example: 2000pgmr /h 3.2 REPEATER PROGRAM SOFTWARE 3.2.1 INSTALLING THE SOFTWARE The options can be entered in any order. For example: 2000pgmr /d /b /c • When you receive the programming software, make a backup copy and store the master in a safe place. Copy the distribution disks using DOS DISKCOPY command. For example, type: COM Port The Johnson programming software defaults to serial port COM1. However, if this port is already in use, the software can be reconfigured to use serial port COM2. To do this, use one of the following methods: DISKCOPY A: A: (single floppy drive) or DISKCOPY A: B: or C: (multi-drive systems). 1. When running the compiled (.EXE) version, type / c2 on the command line after the program name. For example: 2000pgmr /c2 or -c2 If you have a hard disk drive, you may want to create one or more separate directories for transceiver programming and then transfer the program disk files to those directories. To create a new directory, use the MKDIR command. For example, to create directory RADIOPRG, type: 2. Select COM port from Utilities heading. BAUD RATE The software defaults to 9600 baud, however this rate can be changed. To do this from the command line, type /bxxxx (xxxx = baud rate). For example: 2000pgmr /b or -b MKDIR \RADIOPRG. Then to make the new directory the current directory, use the CHDIR command. For example, to change to the \RADIOPRG directory, type NOTE: When the baud rate is changed on the command line the baud rate jumpers on J3 in the MPC must also be changed to the same baud rate (see Section 6.10.8). CHDIR \RADIOPRG. To copy all files from a floppy disk in drive A: to this directory, type: DEMO MODE COPY A:*.* To view the screens for Read Setup Parms and Write Setup Parms from the Transfer menu when a repeater is not connected to the computer this option is used. Normally these screens are not available without a repeater connected. To do this from the command line, type: /d or -d. If you have a single floppy drive and no hard disk drive, you need to create programming disks. The reason for this is that there is not adequate space on the backup disk(s) for storing radio files. If your computer has dual floppy disk drives, the backup disk can be placed in one drive and then the radio files stored on a disk in the second drive. For example: 2000pgmr /d May 2000 Part No. 001-2008-204 3-2 SOFTWARE are also being loaded into conventional memory. Contact Customer Service for information on how these programs can be moved or disabled to make more space available. To make a programming disk, format a blank disk using FORMAT B: or FORMAT B: /S (use "/S" if it must be a bootable disk). Then copy the required program file or files to the programming disk. To do this, type COPY A:(filename.ext) B:(filename.ext). For example, to copy the file 2000pgm2.exe from drive A to drive B, type 3.3 REPEATER PROGRAMMER When the program is loaded into the computer and executed, the menu shows the files available from the directory. The program is used to create, edit, transfer and receive the repeater and channel parameters described in Section 5. COPY A:2000pgm2.exe B:2000pgm2.exe This procedure works for either single or dual drive computers. Refer to your computer reference manual for more information on these DOS commands. IMPORTANT The programming software is shipped in a compressed format. The name of the compressed file is 2000pgm2.exe and it extracts the following files so the program can be used on a PC. 2000PGMR.EXE 2000PGMR.HLP TESTM8L.HLP 2000PGMR.LNF TESTM8H.LNF TESTM8L.LNF TESTM9H.LNF TESTM9L.LNF TESTT8L.LNF TESTT9L.LNF The commands and displays referred to in this manual are for the IBM PC and may differ from IBM compatible.

Under the menu heading Test are the alignment procedures for the PA (see Section 7.3), Receiver (see Section 7.1), Exciter (see Section 7.2) and overall Full Repeater (see Section 7.5) including the MAC card (see Figure 3-1). The 2000PGM2.EXE file is self extracting which means that the files extract automatically when executed. To extract these files so the program can be used, first make the current directory the destination directory for these files. For example, to make it the \RADIOPRG directory on drive C: (if not the current directory), type C: (Return) and then CD \RADIOPRG as just described. To make it the disk in drive B:, simply type B:. Then insert the program disk in drive A: and type A:2000PGM2 (or B: 2000PRM2 if drive B: is being used). The program files are automatically extracted into the current directory or disk.

This menu programs the repeater parameters and options of each repeater at a site. Table 5-1 lists the parameters that are set by this screen (see Figure 5-1) and gives a brief description of each. • The local microphone connected to the MAC jack is assigned a Group ID for transmitting when the local microphone PTT is active. This allows the Repeater to operate as a base station. • Test Mode ID Channel Number This is the Group ID transmitted when the Repeater is in Test Mode. Mobiles with the same Group ID can communicate with the Repeater in Test Mode. Each repeater is programmed with a channel number (1-920). NOTE: Repeater program channel numbers 1-599 increment in 25 kHz steps. Program channel numbers 600-920 increment in 12.5 kHz steps. See Appendix A to determine the correct operating frequency. • Local Mic ID Repeater Number Each repeater is programmed with a repeater number from 1-20. Make sure that this number agrees with the Home repeater number programmed in the mobiles assigned to this repeater. • CWID Message FCC regulations require that the station call letters be transmitted periodically on the lowest- frequency repeater in the system and disabled on all the others. Morse code is used to encode these letters/ numbers for continuous-wave (CW) transmission (15 characters/numbers UPPER CASE). NOTE: The parameters are shown in the lower left of the pop-up screen for reference. • Stand Alone • RF Power Level This is the default power level. Enter the power level for transmit power. Telco Network Type NOTE: This is not the actual power out level. Other factors must be considered for true power out.

Use the Space bar to toggle through the parameters: Disabled, Active Low, Active High, for each alarm. This indicates the primary power source for the Repeater (AC/DC). If AC is selected and Battery Backup is installed, the transmitter goes to half rated power (max.) when AC fails. If DC is selected and AC fails, power output is unchanged. • • There are four input alarms that can be activated by external devices (see Section 6.12). These inputs can be disabled, energized or de-energized. Alarms 3 and 4 can also be analog input. Paging This indicates if there is an optional paging terminal connected to the repeater. This option is not compatible with the LTR Data Modem, TIC or VNC options. • Input Alarms If the input is disabled, the input alarm line is inactive. When energized and current flow is detected, the alarm is activated. When de-energized and no current flow is detected, the alarm is activated. Analog inputs provide a detection of an analog input out of limit condition. Select the Low and High Limit pair to trip an Analog Input Alarm. The High Limit must be greater in value than the Low Limit (0.0V-5.0V in 0.1V steps). Data Modem This is selected if the Data Modem option is installed. This option is not compatible with Paging, TIC, or VNC. 4.3.2 SELECT REPEATER Select the repeater number to be programmed or edited from the pop-up menu (see Figure 4-6).

The time stamp is included because messages are sent continually and this provides a reference for when a data exchange took place. High Speed Data Bus (HSDB) connects all repeaters at a site and continually sends updates on the status of each repeater. This information screen provides a list of all repeaters at the site (1 to 20). If a repeater is not sending data, IDLE is next to the repeater number. The data sent by the repeater is used to determine the Home, GID and UID of destination (mobile) users to receive the call placed by the originator. Figure 4-21 MOBILE TRAFFIC MONITOR 4.5.3 RF DATA The Home column refers to the Home repeater number of the originator, therefore the Repeater number and the Home number may not be the same number. The UID is the Unique ID used to identify the originator of special calls. The GID column refers to the Group ID of the talk group of the originator (236=UID Call, 237 Telco call). The GoTo column shows the repeater channel all destination users switch to so they receive the call. The A/D Monitor Screen shows the state of the lines (see Figure 4-22). These lines are monitored by the A to D converter in the IAC. The normal values for each line are defined as follows.
