INTRODUCTION AND OPERATION

1.12.4 POWER SUPPLY

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 powe r supply to pr ovide automa tic battery revert in the event of AC power failure (see Section 2.5) The Batt ery Back-Up module char ges the batteries when AC is present at the power supply (see Section 2.4 and 8.5).

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.

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.

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.

1.13.4 MOBILE TRANSCEIVERS

The mobile and handheld transceivers used in an LT R system must be comp atible with the type of signaling in use and also the frequency range.

1.14 REPEATER DATA BUS SIGNALING

1.14.1 GENERAL

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.

1.13.2 HOME REPEA TERS

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.

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

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 t he data bus. If a ll rep eater s 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.

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 unassi gned , nothi ng app ear s in that time sl ot.

INTRODUCTION AND OPERATION

1.14.2 MOBILE DATA MESSAGE ORDER

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 mobi les 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 re peater.

The sequence of data messages transmitted on a home repeater is as foll ows: Every t hird 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- re pea ter system are making ca ll s. 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 OPERATION

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 combin ation is detec ted, the ID Validator places in time slot 21 the number of the repeater being used by t he inval id mobile and al so 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 repeate r position of its time s lo t t o in dicate to the ID validator that turn-off has occurred.

SECTION 2 INST ALLATION

INSTALLATION

2.1 INTRODUCTION

Information in this section tells how to set up the repeater for operat ion 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. Performance testing is described in Sections 7.1, 7.2, 7.3 and 7.4.

2.1.1 SITE PREPARATION AND ANTENNA IN-

STALLATION

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 in formation.

2.2 ENVIRONMENT

The following conditions should be considered when selecting a site for the Repeater.

NOTE: If the Repeater is installed in an area that exceeds these environmental conditions, the site should be equipped with air filters to r emove dust an d dirt that could cause the equipment to overheat. The cabinets and filters should be placed on a maintainence schedule.

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 h eat exchan ger, i.e. air conditioner, is then required to cool the cabinets. The air conditioners must be suited for the environment. Each repeater (75W) requires >1200 BTU/hr dissipation to maintain exterior cabin et temperatu re. Each power (160W or 175W) requires >2100 BTU/hr dissipation to maintaim exterior cabinet temperature.

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.

low power

high

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/m

For equipment operating in an uncontrolled envi-

ronment with the Repeaters rack mounted, the airborne particles must not exceed 100 µg/m

1. The Repeaters should b e mounte d 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 th e Repeater for removal.

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.

• Cabinet enclosures must provide air vents for ade-

quate air circulation.

• Temperature and humidity must be considered

when several Repeaters are installed at a si te . Thi s might require air conditioning the site.

INSTALLATION

2.4 AC POWER

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.

The 120V AC cord is a standa rd 3-wi re gro unde d 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 rep eat er s in a rack should not be on the same breaker in order to provi de one operational repeat er in the event a breaker trips. An AC surge protector is recommended for all equipment.

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.

The VIKING VX Repeater power supply can be equipped with an optional 24V DC back-up in the event of AC p ower 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).

2.5 BATTERY BACKUP

If the power supply is equipped with battery backup, screw lugs are provided on the front of the power supply for battery co nnections ( see Figure 2-1). A switch is provi ded fo r 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 cabl e is shown in Fi gure 2-2. LED indicators are provided to show Reverse Battery connection, Charger On/Off and Battery Fault.

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.

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 res et by toggling the Ena ble Li ne or removing A C power for more than 10 seconds.

INSTALLATION

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.

2.7 GROUNDING

CAUTION

PROPER SITE GROUNDING AND LIGHTNING PROTECTION ARE VERY IMPORTANT TO PREVENT 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 grounding eliminates shock hazard, protects against electromagnetic 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 buildin g management or arc hitects. 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.

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 co axial cables for any ground connections required by the secondary protectors.

• RF

An RF protector keeps any lightning strike to the antenna feed line or tower from damaging the Repeaters. Instal l this protection in-line w ith the comb iner 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.

Vp 1.414 X() P 50()()=

where: V

= Voltage at the output of the combiner.

P = repeater output in watts

Vp 1.59782 60 50()()=

Vp 1.59782 54.772256()=

= 87.52V

• Telephone Line

There are four types of pr ote ct ion 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.

May 2000 Part No. 001-2008-204

The hybrid protector is ideal for Transcrypt Internation, Inc. equip me nt, and is strongly r ecommended. A hybrid suppressor c ombi nes s eve ral forms of protection not available in just one type of device.

2-4

Page 29

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-power ed thr ee-element gas tube fires, grounding Tip and Ring.

2.7.1 PROTECTION GUIDELINES

Follow these guidelines for grounding and lightning protection. Each Repeater instal l ati on si te 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 ga uge solid wi re or braid ed wire straps.

• With surge protectors, ensure that ground wires go

directly to grou nd, and not through other equipment.

INSTALLATION

• Run the ground wire for RF coax protect ors directly

to ground.

• With coax protecto rs, ensure maximum instanta-

neous voltage does not exceed the rated voltage.

• Do not run ground wire s parallel t o any other wir ing

(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 INSPECTION

Transcrypt 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 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. Contact Customer Service for assistance (see Section1.7).

tions are shown in Figure 2-8. 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.

3.1 INTRODUCTION

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.

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 t o 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

This manual introduces the program and illustrates how to use the features. This manual is organized to easily fi nd programming information wi th the Table of Contents, Index and Parameter Tables for the responses required for programming.



Follow the computer instructions fo r 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 DESCRIPTION

The programming software is designed to run on an IBM PC or compatible computer that meet the following 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 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 th e computer. This port is standard with most computers.

Graphic reproductions of the screens are shown for reference. Adjacent to the screens are tables to provide the paramete rs, availa ble respon ses and a bri ef description of the parameter. It is not the intent of th is 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.

, format and make backup cop-

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 023-5800-

016. The cab le from the adapter to the repeater has a DB-9 to 8-pin connector (see Figure 4-30).

3.1.4 EEPROM DATA STORAGE

The data pr ogrammed i nto 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-

out affecting progr ammin g. Since EEPROM memory is also reprogrammable, a new dev ice is not needed if programming is changed.

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

The options can be entered in any order. For example: 2000pgmr /d /b /c

• COM Port

The Johnson programming software defaults to serial port COM1. However, if this port is already in use, the software can be reconf igure d to us e ser ial p ort 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 -c2

2. Select COM port from Utilities heading.

BAUD RATE

The software defaults t o 9600 baud, ho wever thi s rate can be changed. To do this from the command line, type /bxxxx (xxxx = baud rate). For example: 2000pgmr /b or -b

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).

DEMO MODE

3.1.6 COLOR OR MONOCHROME OPERA TION

The program ming 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 Utilitie s heading.

3.2 REPEATER PROGRAM SOFTWARE

3.2.1 INSTALLING THE SOFTWARE

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:

DISKCOPY A: A: (single floppy drive)

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 director ies. To create a n ew directory, use the MKDIR command. For example, to create dir ectory 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:

To view the screens for Read Setup Parms and Write Setup Parms from the Transfer menu when a repeater is not conne cted to t he computer t his opti on is used. Normally these screens are not available without a repeater connected. To do this from the command line, type: /d or -d.

For example: 2000pgmr /d

May 2000 Part No. 001-2008-204

COPY A:*.*

If you have a single floppy dr ive and no hard di sk drive, you need to create programming disks. The reason for t his is that there is not adequate spa ce 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.

3-2

Page 39

SOFTWARE

T o make a pro gramming di sk, 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 pro gra mmi ng di sk. 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

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.

The programming software is shipped in a compressed format. The na me of the compressed file is 2000pgm2.exe and it extr acts the fo llowing fi les so the program can be used on a PC.

2000PGMR.EXE 480K 2000PGMR.HLP 42K TESTM8L.HLP 2K 2000PGMR.LNF 173K TESTM8H.LNF 11K TESTM8L.LNF 225K TESTM9H.LNF 11K TESTM9L.LNF 208K TESTT8L.LNF 53K TESTT9L.LNF 51K

The 2000PGM2.EXE file is self ex tr act i ng 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 file s. For example, to make it the \RADIOPRG directory on drive C: (if not the current directory), type C: (Retur n) 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 is used to create new files and set or change the repeater operating parameters. The filename for the repeaters in this file is shown in the lower left corner of the sc reen.

4.3.1 SETUP PARAMETERS

First see Section 4.3.4 to select repeater type to setup LTR Parameters. 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 giv es a brief desc ription of each.

NOTE: The parameters are shown in the lower left of the pop-up screen for reference.

• Repeater Number

Each repeater is programmed with a repeater number from 1-20. Make sure t hat t his nu mber agrees with the Home repeater number programmed in the mobiles assigned to this repeater.

• Channel Number

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 c orrect operating frequency.

• Telco Network Type

None is used for LTR system repeaters.

• Area

This is the same as the area bit used when pro-

gramming the mobiles. This bit is usually "0".

• Sync Repeater

None is used for LTR system repeaters.

• Stand Alone

Select if the repeater is not connected to addi-

tional repeaters via the high speed data bus.

• ID Validator (No t applicable at this time.)

• CWID Time

The time interval between transmission of the

repeater’s CWID message.

• CWID Message

FCC regula tions 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).

• Local Mic ID

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

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.

• RF Power Level

This is the d efault power level. Enter the power level for transmit power.

NOTE: This is not the actual power out level. Other factors must be considered for true power out.

Use the arrow keys to move down the list. Use the Space bar to toggle through the parameters: Disabled, Active Low, Active High, for each alarm.

• Input Alarms

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.

If the input is disabled, the input alarm line is inactive. When en ergi zed and c urrent 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).

• Alarm Description

This is a tex t string (up to 15 characters) to describe the alarm. This test string is sent via Morse code if the alarm input is programmed with a Tx ID and an output is selected in the cross reference menu (see Figure 4-10).

• Transmit ID

Each of the 8-alarm outputs can be assigned a Group ID from 1-225. The default setting is 0 (zero) for disabled. This Group ID and the Repeater number identify an alarm that is active. This ID can be programmed into a transceiver so that when the alarm is active, the alarm description is received in Morse code.

• Alarm Transmit Rate

This sets the time interval for transmitting the alarm message in Morse co de. I f mor e th an one al arm is active, this is the inter-alarm time.

• Cross Reference

The cross reference screen selects the output alarm that is activated by each input alarm. There are up to 48 alarms (0-47), 8 external input alarms and 40 internal alarms (s ee Table 1-2). There are eight output alarms. An alarm condition on any input can cause an output alarm. This screen configures which input alarm activates an output alarm.

4.5.1 HSDB MONITOR

High Speed Data Bus (HSDB) connects all repeaters at a site and cont inu ally sen ds update s 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 receiv e the call placed by the originator.

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.

Group ID, GoTo Channel Number, Free Channel Number and Priority of the current repeater. The time stamp is included because messages are sent continually and this provides a reference for when a data exchange took place.

This is an information screen used at the repeater site while t he computer (laptop) is connected to the MPC in the rep eater being monitored. This information is contained in the receive data stream exchanged between the repeater and the destination user (mobile) and the data content of the repeater transmit data stream. The message contains data received from the destination and data se nt to the mo bile by the r epeater. The repeater receives the destination’s: Uniqu e ID, Home Repeater Number, Group ID, Priority, Status and Time Stamp. The information sent to the destination in the update message from the repeater includes: Unique ID of originator, Home Repeater Number,

Valu es with no lab el are the actual A to D read-

ing. To calculate the voltage on the line, divide the value by 51. Example: Value ÷ 51 = Volts. Any variation from the above values may indicate a problem in that area. Values on this screen are relative measurements only.
