1.8 FACTORY RETURNS
Repair service is normally available through local
authorized E.F. Johnson Land Mobile Radio Service
Centers. If local service is not available, the equipment
can be returned to the factory for repair. However, it is
recommended that you contact the Customer Service
Department before returning equipment because a ser-
vice representative may be able to suggest a solution
to the problem so that return of the equipment would
not be necessary.
Be sure to fill out a Factory Repair Request Form
#271 for each unit to be repaired, whether it is in or
out of warranty. These forms are available free of
charge by calling the repair lab (see Section 1-4) or by
requesting them when you send a unit in for repair.
Clearly describe the difficulty experienced in the space
provided and also note any prior physical damage to
the equipment. Then include a form in the shipping
container with each unit. Your telephone number and
contact name are important because there are times
when the technicians have specific questions that need
to be answered in order to completely identify and
repair a problem.

1.12 REPEATER OPERATION
1.12.1 MAIN PROCESSOR CARD (MPC)
Refer to Figure 1-4.
•Programming Jack
J1 provides input connection from the computer
and the "flash memory" in the MPC. The program-
ming information in an IBM PC programs the MPC
directly from the serial card through an interconnect
cable to the COM1 or COM2 port.
•Reset
S1 provides a manual reset of the Main Processor
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
for an example of this type of alarm.

1.12.4 POWER SUPPLY
The 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 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 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 (85W) 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

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 85W
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 85W
repeater (25A per 175W repeater) or 75A for 5-85W
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 85W 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.

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
1.20 1.50 : 1
1.30 1.86 : 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.

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

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.

SOFTWARE
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)
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.
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)
and overall Full Repeater (see Section 7.5) including
the MAC card (see Figure 3-1).

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.

•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.

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).

(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.
NOTE: More than one alarm condition can have the
same output alarm (see Figure 4-10).

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.
Figure 4-21 MOBILE TRAFFIC MONITOR
4.5.3 RF DATA
The A/D Monitor Screen shows the state of the
lines (see Figure 4-22). These lines are monitored by
the A to D converter in the IAC. The normal values
for each line are defined as follows.
Synthesizer Lock Lines Yes or No
Forward Power (LP) 25-85 Watts
Forward Power (HP) 885-175 Watts
Reflected Power 0-6 Watts
Final Out (ratio) approx equal
Chassis Temp 27°C-55°C
Wideband Audio Output approx 200
LO Injection approx 200
RSSI 20-150
Fan Current 100-200, 0

Power Supply Temp 22°C-45°C
Battery Voltage 21V-28V
Values with no label 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 varia-
tion from the above values may indicate a problem in
that area. Values on this screen are relative measure-
ments only.

4.5.4 REVISION/VERSION
The Revision/Version is displayed for the
repeater modules in this screen. The format is R.V
(revision.version) for all modules. The MPC informa-
tion also includes the release date of the software and
the serial number of the repeater.

4.5.5 MODE SELECT
The Mode Select screen places the repeater either
in the Normal mode or the Test mode. In the Normal
mode the repeater operates as a normal repeater.
In the Test mode the repeater transmits a test
word. This test word is the Test Mode ID setup in the
Setup Parameters (see Section 4.3.1).
C A U T I O N
While in the test mode the repeater is "busy",
therefore it is important to place the repeater
in Normal mode when the test mode is no
longer required.
