Card (MPC). A manual reset causes a complete

power-up restart.

•Display and LEDs

Each combination of DS1 display read-out and

CR4/CR5 indication refers to an active alarm. See

Table 1-2 for alarms and definitions. LED indica-

tions: CR1 is blinking; MPC is operational, CR2 on;

high power, off is low power and CR5 on; indicates an

LTR Repeater.

Figure 1-3 ALARM IN TEST MODE

Alarms

When the Repeater is in Test mode the safety

measures are disabled. Therefore, if the Repeater is

keyed for an extended period and the power amplifier

temperature increase, thermal shutdown will not

occur. There are pop-up windows that appear in the

Test mode screens to alert the user that there is an

alarm and action should be taken. Refer to Figure 1-3

•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

J102 provides audio input from a microphone.

J101 provides the receive audio to the microphone.

•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.

•A D Level Test Point

identification requirement. The CWID is programmed

into the repeater memory. This indicator also is used

when an alarm is transmitted with Morse code.

•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 chan-

nel and not re-access the system when responding to a

call.

•Switch Call Indicator

Not used in the LTR repeater.

•Mobile Call Indicator

Mobile-to-repeater transmission in progress is

indicated by the Mobile Call Indicator.

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 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.

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-

TION

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

LTR system must be compatible with the type of sig-

naling in use and also the frequency range.

1.14 REPEATER DATA BUS SIGNALING

1.14.1 GENERAL

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 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 OPERATION

1-9 May 2000

Part No. 001-2008-204

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 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 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 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.

INSTALLATION

SECTION 2 INSTALLATION

2.1 INTRODUCTION

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.

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-

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 information.

2.2 ENVIRONMENT

The 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 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 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.

INSTALLATION

May 2000

Part No. 001-2008-204

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 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 BACKUP

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 con-

nection, Charger On/Off and Battery Fault.

Figure 2-1 BATTERY BACKUP CONNECTOR

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 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.

Overall Efficiency: >70% at 100V AC

>80% at 240V AC

Lightning protection: 6kV for < 1ms

Power Factor: >0.97 at full load

Brown Out Voltage: 80V AC

Power factor correction per IEC555. The Power

supply has the following safety agency approvals

pending: UL1950, CSA22.2-950, TUV EN60950

(IEC950)

When the AC input voltage is below 90V AC, the

maximum output power is decreased to keep the input

current constant. 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.

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 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.

•RF

An 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 watts

X= for VSWR=

1.05 1.10 : 1

1.09 1.20 : 1

1.13 1.30 : 1

1.17 1.40 : 1

Example: Repeater power output of 60W with a

VSWR of 1.3 : 1 (for this VSWR, X = 1.13):

VP = 87.52V

•Telephone Line

There 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.

2-5 May 2000

Part No. 001-2008-204

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 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 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 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 REPEATERS

If 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 INSTALLATION

VIKING 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 SETTINGS

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

Refer 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.

2.10 CONNECTING RECEIVE AND TRANSMIT

ANTENNAS

Receive and Transmit antenna connector loca-

tions are shown in Figure 2-8. 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.

SECTION 3 SOFTWARE

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 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

This 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 STARTED

NOTE: 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 DESCRIPTION

The 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 card

Although 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 STORAGE

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-

SOFTWARE

3-2

May 2000

Part No. 001-2008-204

out affecting programming. Since EEPROM memory

is also reprogrammable, a new device 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 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 -c2

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

NOTE: 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 MODE

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 with-

out a repeater connected. To do this from the com-

mand line, type: /d or -d.

For example: 2000pgmr /d

3.1.6 COLOR OR MONOCHROME OPERATION

The 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 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 DISK-

COPY 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 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.

SOFTWARE

3-3 May 2000

Part No. 001-2008-204

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 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, 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 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 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 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:. 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.

3.2.2 MINIMUM FREE MEMORY REQUIRED

Approximately 525K of free conventional mem-

ory is required to run this program (use the CHKSK or

MEM command to display the amount of free mem-

ory). If you have at least 640K of memory and not

enough is available, there may be other programs that

are also being loaded into conventional memory. Con-

tact Customer Service for information on how these

programs can be moved or disabled to make more

space available.

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 parame-

ters described in Section 5.

I M P O R T A N T

The commands and displays referred to in this manual

are for the IBM PC and may differ from IBM compati-

ble. Refer to the computer’s operating system manual

for command explanations.

3.3.1 PROGRAM FILES

The files that appear in the program directory are

needed for program operation.

3.4 ALIGNMENT SOFTWARE

The software for the Summit QX repeater pro-

grams the MPC to open and close the audio/data gates

necessary for the alignment selected from the Test-Full

Repeater menu. 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)

name for the repeaters in this file is shown in the

lower left corner of the screen.

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 gives a brief description 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 that this number 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 num-

bers 600-920 increment in 12.5 kHz steps. See Appen-

dix A to determine the correct 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 (Not applicable at this time.)

•CWID Time

The time interval between transmission of the

repeater’s CWID message.

•CWID Message

FCC regulations require that the station call let-

ters be transmitted periodically on the lowest- fre-

quency 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 default 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.

PULL DOWN MENUS

•Power Source

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.

•Paging

This indicates if there is an optional paging termi-

nal connected to the repeater. This option is not com-

patible with the LTR Data Modem, TIC or VNC

options.

•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

4.3.3 ALARM CONFIGURATION

This programs the input alarm (see Figure 4-8)

and output alarm (see Figure 4-9) configurations and

provides a cross reference screen.

Figure 4-7 ALARM CONFIGURATION

Use the arrow keys to move down the list. Use

the Space bar to toggle through the parameters: Dis-

abled, 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 energized and current flow is detected,

the alarm is activated. When de-energized and no cur-

rent 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 text 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 pro-

grammed 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 code. If more than one alarm

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 (see 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 continually sends updates on the

status of each repeater. This information screen pro-

vides 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 origi-

nator.

The Home column refers to the Home repeater

number of the originator, therefore the Repeater num-

ber and the Home number may not be the same num-

ber. 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.

Figure 4-20 HSDB MONITOR

4.5.2 RECEIVE/TRANSMIT DATA

This is an information screen used at the repeater

site while the computer (laptop) is connected to the

MPC in the repeater being monitored. This informa-

tion 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 sent to the mobile by the repeater.

The repeater receives the destination’s: Unique ID,

Home Repeater Number, Group ID, Priority, Status

and Time Stamp. The information sent to the destina-

tion in the update message from the repeater includes:

Unique ID of originator, Home Repeater Number,

Group ID, GoTo Channel Number, Free Channel

Number and Priority of the current repeater. The time

stamp is included because messages are sent continu-

ally and this provides a reference for when a data

exchange took place.
