INTRODUCTION AND OPERATION1-8May 2000Part No. 001-2008-2041.12.4 POWER SUPPLYThe 2000 Series Repeater Power Supply is a quad output 800W supply with power factor correc-tion. 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 REPEATER INFORMATION1.13.1 INTRODUCTIONNOTE: 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 con-trol and signaling functions on that channel. Informa-tion is exchanged between repeaters via a high-speed data bus (modular cable). No system controller is required.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 Valida-tor Manual, Part No. 001-4408-501 and Johnson Tele-phone Interconnect Card Manual, Part No. 004-2000-370 for detailed information.1.13.2 HOME REPEATERSAll 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.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 code and Home repeater number are the "address" of the mobiles in the system. Therefore, up to 1250 sep-arate addresses can be assigned in a 5-repeater system and up to 5000 can be assigned in a 20-repeater sys-tem. An ID code may be assigned to an individual mobile or a group of mobiles as required.1.13.3 INTER-REPEATER DATA COMMUNICA-TIONData 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.1.13.4 MOBILE TRANSCEIVERSThe mobile and handheld transceivers used in an LTR system must be compatible with the type of sig-naling in use and also the frequency range.1.14 REPEATER DATA BUS SIGNALING1.14.1 GENERALA single-line serial data bus interconnects the logic units of all the LTR repeaters at the site. The first repeater powered on generates the synchroniza-tion pulse that is used by all other repeaters to deter-mine 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 num-ber 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.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.

INTRODUCTION AND OPERATION1-9 May 2000Part No. 001-2008-2041.14.2 MOBILE DATA MESSAGE ORDEREach 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.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 mes-sages 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.1.14.3 ID VALIDATOR OPERATIONIf 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 Vali-dator 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 trans-mits the turn-off code (31) to the mobile receiving the call. That mobile then squelches and resumes moni-toring 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.

2-1 May 2000Part No. 001-2008-204INSTALLATIONSECTION 2 INSTALLATION2.1 INTRODUCTIONInformation 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.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. Per-formance testing is described in Sections 7.1, 7.2, 7.3 and 7.4.2.1.1 SITE PREPARATION AND ANTENNA IN-STALLATIONSite 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.2.2 ENVIRONMENTThe following conditions should be considered when selecting a site for the Repeater.Operating Temperature.-30°C to +60°C (-22°F to +140°F). Humidity.Less than 95% relative humidity at 50°C.Air Quality.For equipment operating in a controlled environ-ment with the Repeaters rack mounted, the airborne particles must not exceed 30 µg/m3.For equipment operating in an uncontrolled envi-ronment with the Repeaters rack mounted, the air-borne particles must not exceed 100 µg/m3.NOTE: If the Repeater is installed in an area that ex-ceeds these environmental conditions, the site should be equipped with air filters to remove dust and dirt that could cause the equipment to overheat. The cabinets and filters should be placed on a maintainence sched-ule.When the repeaters are installed in an environ-ment 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 dissi-pation to maintaim exterior cabinet temperature.2.3 VENTILATIONThe 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 consider-ations when installing Repeaters to provide adequate air circulation.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.NOTE: Repeaters should not touch. Leave a mini-mum of one empty screw hole (approximately 1/2") between repeaters vertically especially for bottom ventilation slots in high power repeaters.•Cabinet enclosures must provide air vents for ade-quate air circulation.•Temperature and humidity must be considered when several Repeaters are installed at a site. This might require air conditioning the site.

INSTALLATION2-2May 2000Part No. 001-2008-2042.4 AC POWERThe 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 opera-tion. However, a 240V AC outlet requires that the 120V AC power plug be replaced. A locking AC power cord is provided for the supply.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.Each Repeater requires an outlet, so for a 5-chan-nel system, a minimum of 5 outlets is required. An additional three outlets should be added for test equip-ment. 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.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 multi-coupler requires another 0.5A for a total system requirement at 24V DC of 75.5A for 75W repeaters (125.5A for 175W repeaters).2.5 BATTERY BACKUPIf 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 con-nection, Charger On/Off and Battery Fault.Figure 2-1 BATTERY BACKUP CONNECTORFigure 2-2 TEMPERATURE SENSOR CABLE2.6 800W POWER SUPPLYThe 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 run-ning any 2000 series repeater. Each output is overload protected such that the power supply current limits and automatically resets when the overload is removed (see Table 2-1). 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.B- B+ TEMP ACTIVECHARGERONCHARGERFAULTBATTERYBATTERYREVERSEGROUNDEARTHNEUTRALLINESWITCHBATTERYTEMPTERMINALNEGATIVEGNDBLKWHT

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.Figure 2-3 POWER CABLE CONNECTOR AND SCHEMATIC971211108654321ABCJ2123456789REPEATERBACKPLANEAC FAIL INPOWER SWITCHTHERMAL SENSOR+15VN/CN/C-5VTOPOWER HARNESSGROUND+15V+5VTORFIB+26.5VABC123456789101112369852147J2BACKPLANEN/C

INSTALLATION2-4May 2000Part No. 001-2008-204The 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.2.7 GROUNDINGCAUTIONPROPER SITE GROUNDING AND LIGHTNING PROTECTION ARE VERY IMPORTANT TO PRE-VENT PERMANENT DAMAGE TO THE REPEATER.As in any fixed radio installation, measures should be taken to reduce the possibility of lightning damage to the Viking VX equipment. Proper ground-ing eliminates shock hazard, protects against electro-magnetic interference (EMI) and lightning.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.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.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.Secondary protection (other than grounding) pro-vides the equipment protection against line transients that result from lightning. There are two types of sec-ondary protection, RF and Telephone Line. Use the same wire sizes as specified for coaxial cables for any ground connections required by the secondary protec-tors.•RFAn RF protector keeps any lightning strike to the antenna feed line or tower from damaging the Repeat-ers. Install this protection in-line with the combiner and antenna feed line.RF protectors are selected by calculating the maximum instantaneous voltage at the output of the combiner. Do this by using the following equation. where:VP = Voltage at the output of the combiner.P = repeater output in wattsX= for VSWR=1.05 1.10 : 11.09 1.20 : 11.13 1.30 : 11.17 1.40 : 11.20 1.50 : 11.30 1.86 : 1Example: Repeater power output of 60W with a VSWR of 1.3 : 1 (for this VSWR, X = 1.13):VP = 87.52V•Telephone LineThere are four types of protection suppressors for telephone lines; Gas Tube, Silicon Avalanche Diode, Metal Oxide Varistor and Hybrid.The hybrid protector is ideal for Transcrypt Inter-nation, Inc. equipment, and is strongly recommended. A hybrid suppressor combines several forms of protec-tion not available in just one type of device. Vp 1.414 X() P50()()=Vp 1.414 1.13()60 50()()=Vp 1.59782 60 50()()=Vp 1.59782 54.772256()=

INSTALLATION2-5 May 2000Part No. 001-2008-204For 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 GUIDELINESFollow these guidelines for grounding and light-ning protection. Each Repeater installation site is dif-ferent; all of these may not apply.•Ensure that ground connections make good metal-to-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.•With coax protectors, ensure maximum instanta-neous 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.2.8 UNPACKING AND INSPECTIONTranscrypt Internation, Inc. ships the Repeater securely crated for transportation. When the Repeater arrives, ensure the crates remain upright, especially if storing the crates temporarily.When unpacking the Repeater, check for any visi-ble 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. Contact Customer Service for assis-tance (see Section1.7). Figure 2-4 RACK MOUNTED REPEATERSPOWER STRIPTX COMBINERDUPLEXERRX MULTICOUPLER

INSTALLATION2-6May 2000Part No. 001-2008-204If everything appears undamaged, remove the Repeater equipment from the crate, using normal pre-cautions 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 cir-cuit cards) to repack the equipment. You are responsi-ble for proper repacking. Transcrypt Internation, Inc. cannot be responsible for damage to equipment caused by negligence.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.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).2.9 REPEATER DATA BUS INSTALLATIONVIKING VX repeaters with High Speed Data Bus (HSDB) software Version 201 or earlier (refer-ence U14 label) installed on the MPC board must use the optional RJ-11 to BNC Adapter Module (see Table 1-1 and Figure 2-9) to connect the HSDB. Any VIKING VX repeater (regardless of the HSDB soft-ware version, see Section 4.5.4) that connects to a HSDB that is also servicing LTR 8000/8900 repeaters, other VIKING VX repeaters that use VIKING VNC cards, or an ID Validator must also use the adapter module. The BNC Adapter Module is installed on the back of the VIKING VX repeater cabinet (see Figure 2-13 and Figure 2-14).Systems constructed only with LTR VIKING VX repeaters that have Version 202 or later HSDB soft-ware ( 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.2.9.1 MPC DATA BUS SWITCH SETTINGSSwitch 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 SETTINGSRefer to Figure 2-6 for crystal selection and HSDB Code selections jumper placement. The jumper on J5, pins 2-3 selects 12 MHz crystal for LTR. The jumper on J4, pins 3-4 connects EPROM U14, pin 27 (A14) to +5V for LTR single-ended 5V data bus.Figure 2-5 5-CHANNEL COMBINING SYSTEMRECEIVER 1RECEIVER 2RECEIVER 3RECEIVER 4RECEIVER 5RECEIVERMULTICOUPLERPREAMPLIFIERFILTERDUPLEXERTRANSMITTERCOMBINERTRANSMITTER 1TRANSMITTER 2TRANSMITTER 3TRANSMITTER 4TRANSMITTER 5T/R ANTENNABANDPASS

Although each trans-mitter 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.Figure 2-8 ANTENNA CONNECTIONSFigure 2-9 RJ-11 TO BNC ADAPTER MOD-ULE231J5J4 123465HSDB CODE SELECTIONCRYSTAL SELECTION231J5J4 123465HSDB CODE SELECTIONCRYSTAL SELECTIONB- B+ TEMP ACTIVECHARGERONCHARGERFAULTBATTERYBATTERYREVERSEGROUNDEARTHNEUTRALLINESWITCHPIN 2 BLKPIN 3 REDPIN 4 GRNPIN 5 YELPIN 6 BLUPIN 7 GRYPIN 8 BRNORNPIN 2TLA+PIN 1TLA-GRNBLKHSDB-PIN 5HSDB+PIN 6YELBLUPIN 1 ORNPIN 4PIN 3REDIRDB- IRDB+

3-1 May 2000Part No. 001-2008-204SOFTWARESECTION 3 SOFTWARE3.1 INTRODUCTIONThe 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.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 MANUALThis manual introduces the program and illus-trates how to use the features. This manual is orga-nized to easily find programming information with the Table of Contents, Index and Parameter Tables for the responses required for programming.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 STARTEDNOTE: Before starting you should already know how to start MS-DOS, format and make backup cop-ies 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).Follow the computer instructions for loading the disk. 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".3.1.3 COMPUTER DESCRIPTIONThe programming software is designed to run on an IBM PC or compatible computer that meet the fol-lowing minimum requirements.•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 cardAlthough the program uses color to highlight cer-tain areas on the screen, a monochrome (black and white) monitor or LCD laptop also provide satisfac-tory operation. Most video formats such as EGA and VGA are supported. A serial port is required to con-nect the repeater to the computer. This port is standard with most computers.The cables from the repeater to the computer are not included. With most computers, the adapter-to-computer 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 023-5800-016. The cable from the adapter to the repeater has a DB-9 to 8-pin connector (see Figure 4-30).3.1.4 EEPROM DATA STORAGEThe 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-

$SOFTWARE3-2May 2000Part No. 001-2008-204out affecting programming. Since EEPROM memory is also reprogrammable, a new device is not needed if programming is changed.3.1.5 COMMAND LINE OPTIONS•HelpTo show all options available from the command line type: /h or /?. Either ’/’ or ’-’ can be used. For example: 2000pgmr /hThe options can be entered in any order.For example: 2000pgmr /d /b /c•COM PortThe 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:1. When running the compiled (.EXE) version, type /c2 on the command line after the program name. For example: 2000pgmr /c2 or -c22. Select COM port from Utilities heading.BAUD RATEThe 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 -bNOTE: When the baud rate is changed on the com-mand line the baud rate jumpers on J3 in the MPC must also be changed to the same baud rate (see Sec-tion 6.10.8).DEMO MODETo 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 with-out a repeater connected. To do this from the com-mand line, type: /d or -d.For example: 2000pgmr /d3.1.6 COLOR OR MONOCHROME OPERATIONThe programming software utilizes color for a color monitor and video card. However, with LCD-type displays, this may make some information hard to read because the contrast is poor. To improve con-trast, a monochrome mode can be selected in the dis-play mode from Utilities heading.3.2 REPEATER PROGRAM SOFTWARE3.2.1 INSTALLING THE SOFTWAREWhen you receive the programming software, make a backup copy and store the master in a safe place. Copy the distribution disks using DOS DISK-COPY command. For example, type: DISKCOPY A: A: (single floppy drive) or DISKCOPY A: B: or C: (multi-drive systems).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: MKDIR \RADIOPRG. Then to make the new directory the current directory, use the CHDIR command. For example, to change to the \RADIOPRG directory, type CHDIR \RADIOPRG. To copy all files from a floppy disk in drive A: to this directory, type: COPY A:*.*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 com-puter 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.$

$SOFTWARE3-3 May 2000Part No. 001-2008-204To 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 pro-gram 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, typeCOPY A:2000pgm2.exe B:2000pgm2.exeThis procedure works for either single or dual drive computers. Refer to your computer reference manual for more information on these DOS commands.The programming software is shipped in a com-pressed 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 480K2000PGMR.HLP 42KTESTM8L.HLP 2K2000PGMR.LNF 173KTESTM8H.LNF 11KTESTM8L.LNF 225KTESTM9H.LNF 11KTESTM9L.LNF 208KTESTT8L.LNF 53KTESTT9L.LNF 51KThe 2000PGM2.EXE file is self extracting which means that the files extract automatically when exe-cuted. 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:, sim-ply type B:.
