F. A. Q.
(Frequently Asked Questions)
Q. I CHANGED THE PL CODE, but the RRX repeater still encodes the previous tone
A when I key the hand MIC. OR: The Repeater works fine radio—to-radio, but does not
. work with the local MIC on Repeater-to-radr‘o. Why?
When changing tones, be sure to Mme PTI' tone (which is encoded when the key line is pulled low
either by the hand MIC PTl' or an accessory board like RP-200). In a single-tone repeater. the main repeat
mode tone and the PTT tone shay 51 both be set to the same tone. In a rnulliple- lone/ RP-ZOO Repeater;
choose the tone encoded with incoming phone calls as the P'I'I' tone:
green at 1-seconcl intervals. Why?
It you have adjusted the trequencies more by than 4 MHz without readjusting the VCO control voltage,
either or both oi the synthesizers may be out of lock. Although the RRX is programmable, you must retune
TX. RX, TXVCO. RXVCO, FiX heiicals and the duplexer when changing frequencies more than 1 MHz.
0. I CHANGED THE FREQUENCY OF THE REPEATER; now the "STATUS" light flashes
0. HOW DO I SET UP THE INTERFACE to control the FlFIX with a remote?
A You MUST HAVE a termination panel that will convert DC or Tone remote functions to control signais to
. operate the RFlX. Wire the termination panel to RWR—10 port J402 of the RRX control board, then set
RWR-tO to "Installed" for monitor function. (Key-click to "installed" or programmer to 'Y")
. I AM INTERESTED IN PURCHASING AN REX. How well-suited is it for high-RF
A environments?
- The RITFlON HFlX standard 4-cavily Repeater has excellent adjacent channel rejection. Each HF module
is enclosed in an aluminum case, and the main enclosure is a sturdy, heavy-duty aluminum 19" rack-mount
case, which provides good HF isolation. This is suitable for most sites.
NOTE: RRX is avaiiaple without the 4-cavity duplexer:
1. . .to lit a e-cavity Col-Wave or Sinclair ‘nslge the Repeater or
2. . . to use a high-Q external duplexer through 2 back panel 59-239 smkgts. Very high
RF level sites may require greater isoiation provided by a S-cavity duplexer.
0- WHAT IS THE DUTYCYCLE RATING of the RRX Repeater?
A l The S-Watt output power RRX (standard — 5 Walls output from internal duplexer) can be operated
. continuous-duty with the internal power supply and cooling fan.
0 The 30-Wutt output model is rated at 50% (3 minutes ON/ 3 minutes OFF), with the internal power
supply and cooling fan.
NOTE: Be sure to follow good engineering practlces in any instaliation that is not
temperature-controlled.
0. [AM USINGAN RHXASAN EXCITER in a 100-Watt system, and am getting less than
A optimum performance. What can I do ?
. Use these guidelines:
Use double-shielded cable lor all RF connection cables.
Use tz-gauge or larger cabie for the DC power leads.
Eliminate ground loops in the rack.
Use a high 0, high power external duplexer.
Maintain low VSWR through the duplexers lo the antenna.
Tune the FtFlX TX output into the external RF PA of choice.
Be aware certain applications may require the use of a power circulator.
T‘F’Q?QPT‘
Q. WILL THE RRX WORK WITH A 440 MHz BAND APPLICATION?
The RRX transmitter and receiver synthesizers may or may not look in this range depending on part
A. tolerances. A low capacitor changes will remedy this situation; however, this may resuit in a slight
reduction in TX power output.
NOTE: Be aware the duplexer is NOT DESiGNED to tune in the 440 MHz band range,

REX—4501452 MAINTENANCE/REPAIR/ OPERATING MANUAL
IMPORTANT INFORMATION
SURFACE MOUNT REPAIR: FllTFlON surface mount products require special equipment and
servicing techniques. Improper servicing techniques may cause permanent damage to the printed
circuit board and/or components which is not covered by the FtlTFlON warranty. it you are not
completely familiar with surface-mount component repair, FtITRON recommends you defer
maintenance to qualified service personnel.
PRECAUTIONS FOR HANDLING CMOS DEVICES: This radio contains complementary metal—
oxide semiconductor (CMOS) devices requiring special handling techniques. CMOS circuits are
susceptible to damage by electrostatic or high voltage charges. Such damage can be latent, with
the failure not becoming evident for weeks or even months. For this reason, he sure to note the
following precautions whenever you disassemble the radio. These rocedures are even more
critical in Iow- humidity environments.
1) Storage/trgnggort - Place CMOS devices to be stored or transported in conductive material
with all exposed leads shorted together. DO NOT lNSEFtT CMOS devices into conventional-
type plastic ”snow" or plastic trays used for other sorts of semiconductors.
2) grounding - Place all CMOS devices on a grounded bench surtace. All personnel working on
the radio/CMOS circuit must be grounded before handling the radio. Normally effective
procedure is to wear a conductive wrist strap in series with a 1OOKQ resistor to ground.
3) Clothing 4 DO NOT WEAR NYLON Clothing while handling CMOS Circuits.
4) Power off - Remove power BEFORE connecting, removing or soldering a PC board
containing CMOS devices.
5) ngerlvoltage transients - Do not insert or remove CMOS devices with power applied.
Check all power supplies used for testing CMOS devices to be sure no voltage transients are
present.
6) Soldering - Use a grounded soldering iron for CMOS circuitry.
7) Lead-straightening tools - Provide ground straps for tools used to straighten CMOS leads.
NOTE: Use the original packing material and shipping carton if possible, when
returning a repeater unit for service. Take special care to prevent damage
to the rack mounting ears.

INTRODUCTION
GENERAL
HITRON REX-450 and REX-452 are a synthesized rack-mount or table top UHF Repeaters that
operate in the 450 to 470 MHz FM communications band. The unit receives messages originating at
handheld, mobile, or lixed stations on one frequency, and simultaneously retransmits the message
on a second frequency. The unit contains a duplexer which allows a single antenna to be used tor
simultaneous transmission and reception. This full-duplex operation enables mobile and handheld
units to communicate over much greater distance than is possible Without the Repeater.
The RRX-450 and RRX-452 are contained in a heavy~duty standard 19" rack-mount enclosure.
For easy access to the internal modules, remove five screws securing the Repeater cover, then slide
it oft. Modular design optimizes RF isolation and contributes to ease of service. Standard unit
modules are:
Control unit.
Transmitter module,
Receiver module,
Power supply, and
4-cavity notch duplexer.

OPERATION
SPECIAL NOTES
1. TEST THE REFEATER for proper operation as the unit is received, before attempting to
reprogram and/or retune it. Standard factory programming is RX 469.500, TX 464.500, 100Hz
2. RETUNE THE DUPLEXER if you have reprogrammed a TX or RX frequency change by
0.1 MHz or more.
3. RETUNE vco VOLTAGES if you have reprogrammed a frequency change of more than
1.0 MHZ. Flashing GREEN “STATUS“ LED indicates VCO is unlocked.
4. IF PROGRAMMING ERRORS PERSIST:
a. reprogram the unit to factory defaults;
b. reprogram with a PC to desired settings;
0. realign as necessary.
GENERAL
The RRX-450 Repeater can be powered by e +11 to +15 VDC, or 110/240 VAC source. The
Repeater includes a 13.8V battery maintenance charge output, used during normal AC operation to
maintain the charge on an external +12 VDC battery. The battery takes over automatically (tailsafe)
if AC power fails, and the unit automatically returns to AC power when AC is reapplied.
The RRX-450 has standard frequency separation of 5 MHz between transmit and receive
channels. Normal Repeater configuration has the receive frequency higher than the transmit
frequency. “Inverted units" have the transmit frequency 5 MHz higher than the receive frequency.
The duplexer can be mounted with either the low-pass or the high—pass filter toward the transmitter,
as necessary to accommodate inverted—frequency operation.
The output RF power of the transmitter module adjusts from 1 to 8 Watts. 5 Watts nominal at the
duplexer output (1 .8 dB insertion loss in normal mode). RRA-452, an optional RF power amplifier
module that fits inside the Repeater enclosure, has typical power output of 30 Watts, which drops to
20 Watts at the duplexer output.
A time-out timer, a hang-timer and Morse code ID are standard items in the RRX-450. as is
QCTM or DOC tone decode/encode.
This Repeater can locally monitor and transmit via an on—board audio amplifier key circuit, using
the RSMGX Local Speaker/Microphone. The RSM-SX encodes only the QC tone programmed in
the PTT MIC tone, and is different from the "Repeater“ tone unless it is programmed the same.
A 10-pin connector on the main PC board is included to accommodate several RITRON
accessories. See “RRX-450 Accessory," page 5.
NOTE: Certain accessories cannot be installed in the same unit with others; call RtTRON Sales
or Customer Service Departments at 317-846-1201 for details.
The RRX-450 Repeater system can be used with an RP-ZOO autopatch or a Telenexus system
for interconnection with a Public Switched Telephone Network.
The RRX-450 Repeater also includes these features:
- Backup Battery Charger, SOOmA: automatic cut-over to Battery when AC power fails,
then back when AC power is re-applied.
- Auxniary Repeater Controller Connector
- Internal QC or DQC Capability
- Modular Design for quick field repairs and RF isolation
- Rack Mount Enclosure for professional installations 1 Rubber feet for desktop mounting
- User Programmable Functions, programmable by computer or by MIC “key—click"

PROGRAMMABLE UHF FM REPEATER_OperatIon
INSTALLATION
To install and operate the RRX-450 as a Repeater, connect the unit to an antenna that has been
tuned to the transmitter lrequency. Then connect the unit to either a +12 Volt battery or plug it into
an AC outlet. Make sure that the AC voltage selector (rear panel) is set tor the appropriate AC
source (110 or 240 VAC). Remove the voltage selector window with a flat blade, remove the internal
board, then rotate to the correct voltage and replace.
- The red “POWER" LED on the tront panel means the Repeater is ready for operation.
- It the TX LED flashes green, the transmitter must be realigned—refer to page 25.
All intemal adjustments have been factory set. A signal on the Repeater receive trequency
activates the green Carrier Detect (CD) light emitting diode (LED), regardless of tone, A proper tone
signal will cause the Repeater to transmit, confirmed by the red STATUS LED.
TONE SIGNALING
The Repeater’s intemal microcontroller may be programmed with QC (Quiet Call) g DOC
(Digital Quiet Call) to access the Repeater. QC and DOC cannot be stored in the EEPROM at the
same time. The RRX-450 may be programmed with one QC tone, or two DQC codes at a time.
Because the main PC board includes ports for up to three optional HTS—GP QC decode modules,
the Repeater may be operated to accommodate separate groups of users. Each group can have its
own QC/DQC access tone. The optional (QC only) tone module(s) act as a decoder only; tones
program-med into the Repeater are all encoded by the microcontroller IC408,,
NOTE 1: In a multiple tone system, while one (tone) group is using the Repeater, all other user
groups will be locked out of the Repeater until the expiration of the hangtime. In a
Telenexus system, an RP-2OO tone must be set in each unit, the hangtime in the RTLT and
set to .5 seconds (9216), and the hangtime in the RTSU end set to 0 seconds (9200).
NOTE 2: The RP»200 will encode on an incoming telephone call with the tone programmed for P'I'r
operation. Calls initiated by radios will be on the radio's tone.
NOTE 3: The lowest QC tone has to be the microprocessor; extra Tone 1, Tone 2 and Tone 3 boards
(QC tones #2 to 34) must be in ascending QC order to match programming to prevent
"cross-coding“.
CROSS-CODING: SEPARATE QC ENCODE/DECODE SETUP
For systems with mobile and/or portable radios that can be QC encoded, sometimes it is
desirable to operate the RRX Repeater with separate encode and decode codes. Mobiles and/or
portables operating in close proximity to the antenna system can mix LO. and the Repeater
transmitter to create an on—chennel product. In this case, the transmitter having the correct tone
causes the Repeater to “see" itself and to lock up in transmit mode, and to "howl“.
Radios with different I.F. can help alleviate this problem, or the problem can be eliminated by
operating with different encode and decode tones. Perform the tollowing:
1, Select a mobile encode tone and a dillerent decode tone (except 67.0Hz).
Set HTS-GP DIP switches to decode the mobile or portable gmdetone.
Install an HTS-SP into the external 'Tone 1" header, J407.
Set the internal RRX code (Tone $1) to any QC code lower than the tone to be set in
Step 5, below.
Program the RRX Tone #2 location to the portable or mobile awe tone.
Place PJ403 in position 'B" to prevent the on—board circuit trom decoding the code set
in step 4, unless it also is to be used as a valid user tone.
RESULTS: The HTS-GP decodes the proper code, the RRX encodes what is programmed
to match the tone board slot, and on-board decode circuitry is defeated.

PROGRAMMING THE REPEATER
WHAT CAN BE PHOGRAMMED
The RRX-450 Repeater may be programmed with a transmit frequency. receive frequency, 00,
DOC and special features. In addition, the internal microcontroller of the Repeater must be
programmed for use with certain accessories. For example, the micro-controller must be
programmed with QC/DQC tone(s) in order to access RP-ZOO paging interconnect.
Other programmable parameters include:
Batten pggkug cutover beep — When AC power fails and the Repeater has switched to DC backup,
a beep will sound at the beginning of the first transmission and
every 8 seconds thereafter as long as the transmitter remains
keyed.
Transmit time guttime — This feature determines how long the Repeater can broadcast
continuously before the transmitter automatically shuts off.
Tone signaling turn off t'rne— This is the time (in addition to ‘hang-time" with tone) that no tone is
transmitted after the Repeater ceases to detect an incoming carrier
Call sign:Morse code identifier — The Repeater may be programmed to transmit a Morse code
identifier at a specified time interval after activity.
TWO WAYS TO PROGRAM THE REPEATER
The two ways to program the RRX-450 Repeater are:
PCISOFI’WARE: The preferred method, using a PC-compatible computer and the RlTFlON
programming software kit RPTvPCPK, provides on-screen programming instructions. This kit also
includes a cable to connect the computer serial port to the front panel of the Repeater.
See the description and further information on the PCISoftware programming kit on page 11.
PTT: An optional method is to plug a (model RSM-3X) remote speaker/microphone into the
Repeater front panel and program data by pressing and releasing the Push»To-Talk switch (P‘I‘l’).
Refer to the following setup instructions.
PROGRAMMING SETUP: PC/SOFI'WARE 81 PTT
1. Remove AC and DC power from the Repeater.
2. Insert (a.) the programming cable plug, OR; (b.) the RSM-3X plug into the two 'TEST MlC'
jacks on the front panel of the Repeater.
3. Remove a small black plastic plug, located on the right side of the iacks. to uncoveran
access hole in the front panel.
4. Use a pointed tool to press and hold the programming button located in this hole. Hold the
button until power is applied, then release it.
5. a. If you are using PC/software programming, no tone is sounded (as noted below).
Enter "1“ to begin programming; follow on-screen programming instructions. If you
experience software failure, repeat steps 4 and 5.
b. if you are using remote speaker/microphone programming, the Repeater sounds a
1-second tone to confirm it is in programming mode.
6. See Instructions on page 11 to return to operating mode.
PTT PROGRAMMING: NEW CHANNEL CONTENTS
Channel contents are radio frequencies, tones and special features stored in the Repeater
EEPROM. No power is used in retaiing these settings.
To PROGRAM CHANNEL CONTENTS one digit at a time, press, then release the PTT button of
the remote speaker/microphone the number of times equal to the digit value. The unit will emit a
“ready” tone prompt for the next digit.
To STORE CHANNEL CONTENTS after programming all valid content data, press then release
the programming sztch behind the front panel—same as 5.3.4, above. The unit will emit a single
confirming tone indicating the data has been "Iatched' in.
NOTE: A series of beeps indicates an error or an invalid data entry: re-enter the data from the last
valid data latched in.
5.5.1
5.6
PROGRAMMABLE UHF FM FtEPEATER_Programming
PTI' PROGRAMMING: GUIDELINES
' Follow PROGRAMMING SETUP (page B) and RETURNING T0 OPERATING MODE (page 11)
instructions. Be sure to "Iatch»in" the data by pressing the programming button.
- Press the FIT ten times to enter zero (the digit '0").
- While programming a digit, do not pause for more than about one second between presses; an
extended pause tells the mlcrocontroller that you are finished entering the digit.
- EnterALL radio frequencies as six DIGITS: do not skip zero (“0“), or include the seventh digit.
EXAMPLES: - Enter a zero for each of the last two digits in “464500“ (464.500MHz).
- Enter only the first six digits for (12.5 KHz ofiset channel) 7-digit frequency
"461862' (461.8625KH2).
- Although the unit will allow you to program invalid frequencies outside the 450-470 MHZ band,
the FtEPEATER WlLL NOT OPERATE on frequencies outside the 450-470 MHz band.
PTT PROGRAMMINQ; EN E! MIETAKES
if you make a mistake or lose count of your presses, correct your programming entry as follows.
EXAMPLE: If you press the P'I'I’ seven times when intending six times, do not then press the
programming button to store data. Rather, continue pressing the PTT until three beeps sound, then
start over lrom the most recent valid entry. To start over from the beginning, power cycle the
Repeater.
P77 PROGRAMMING: INVALID ENTRIES
When you are in programming mode, an invalid entry is indicated by the Repeater emitting three
tones then a long tone after you press the programming button to store the entry; No
PROGRAMMlNG CHANGE is made for an invalid entry.
EXAMPLE: Attempting to save seven digits as a radio frequency will not work, because all radio
frequencies are entered as six digits. See VALID PROGRAMMING ENTRIES on page 10.
PTT PROGRAMMING: NOTES
1. For modifying tones in a multiple tone application, RITRON strongly recommends you
begin programming using “delete all codes" (P1'I‘"84" code). You can then “ADD“
("51XX') apprOpriate codes one at atima. For CTCSS, make sure the HTS-SP tones are
set higher than the lowest tone. in a multiple~tone configuration, the lowest tone is
decoded by the FlFtX on-hoard microcontroller.
NOTE: Ensure that any added tones are installed in ascending order starting with J407.
(external Tone #1) and the portables are programmed for tone dropout (QC decode).
2. When changing the code in a single CTCSS system, use the 2-digit F'TI' code. Using 81XX
will "ADD“ a code to the existing tone data. Changing code data DOES NOT CHANGE the
P‘I'I’ tone (encoded for the hand-mic). You must also use 91XX to sel the P'l'l' tone.
3. To read out the programmed frequency, press and hold the programming button and tum
ON the Repeater. Press and release the programming button one more time without
entering data to read out TX, then RX codes, than tone data. Count the number of beeps
per group. Ten beeps indicate zero.
4. Where “TX/RX Frequency" appears in the interpretation column, the receive frequency is
5 MHz above the TX frequency.
5. Adding a “9" to the end of a QC or DOC entry tums OFF Quiet Call during transmit. Quiet
Call then operates in receive mode ("decode") only.
6. Adding a "1" to the end of a DOC entry inverts the code for RX and TX.
Adding a “2" inverts the code for RX.
Adding a ‘3‘ invens the code for TX.
7. It the Repeater is to be configured for multiple QC tone operation (HTS-GP modules are
used), the internal, on-board tone programmed into the Repeater must be the lowest tone:
tone(s) programmed for the HTS-GP module(s) must be higher than the “intemal' tone.
8. In an RFtX system containing an RP-200, the fleece controls the Repeater time-out.

28. SIX-CAVITY DUPLEXER INSTALLATION
SIX-CAVITY DUPLEXER INSTALLA’flQN |u§||3ug [IQN5 FQB Bax-450:
A six—cavity, notch—type duplexer (Sinclair M2356 or Cel-Wave PD633-6A) can be
retrofitted inside the RRX~450. Installation kit RIKD—GC—l, described below, provides
the necessary hardware.
NOTCH-TYPE DUPLEXER§= 6-CAVITY 15, MA!" 1:
A six-cavity duplexer offers performance improvement over the standard RITRON (or
any) four-cavity model (RD-451):
- It provides deeper TX and RX notches; an extra cavity per side cream higher Q,
which equates to a deeper notch.
° A six-cavity duplexer may be necessary, or more desirable than a four—cavity, to
block broadband noise, high transmit powers, or co—located transmitters.
' Six-cavity duplexers generally have notches greater than 75 dB, equating to
about 12 dB more rejection (over RD-451), of the TX broadband synthesizer noise
at the RX frequency (Normal Split : TX low, RX high) NOTE: The RD-451 high
frequency notch depth is comparable to the Sinclair or Cel—wave.
NOTE: DO NOT confuse poor duplexer performance with adjacent channel
interference; adjacent channel rejection is purely a function of the receiver.
A ”notch-type" duplexer DOES NOT affect adjacent channel performance
(+/- 25 KHz) of the Repeater. Model RRX-450 adjacent channel specification
is as gmd as or begr M any other synthesized product in its price range.
mum
Align the duplexer 173m installing it, because the tuning screws are not accessible after
it is installed. Alignment accuracy is critical to reduce any de—sense naturally present in
the system. Proper tuning achieves mam'mum notch depth and low SWR simultaneously
° Use a signal generator and spectrum analyzer to perform the alignment.
Terminate the unused port into 50 Ohms.
0 The vertical range on most spectrum analyzers is about 70 dB. When you have
”notch ” the carrier down into the noise floor, increase the generator level 20 to
30 dB to bring the carrier back out of the noise floor. This allows you to tune for
maximum notch depth.
MALLADQN;
If the Repeater includes RTS6P tone boards, remove and discard the left-side (with the
RRX front panel facing you) nylon PC board guides hem you install the duplexer. The
remaining guide and 8-pin header are sufficient to secure the RTS—6P.

RITRON PROGRAMMABLE REPEATER_Six-Cavity Duplexer Installation
SEM INST CNS:
1. Construct two (2) RF patch cables from the furnished partsl
NOTE: Each cable assembly is to include a BNC connector on one end and a
phono plug on the other. Make cables to required length. Bear in mind whether
the RRX—450 is an inverted unit—TX high / RX low‘ Be aware that Sinclair and
Gel-Wave duplexes are not identical in that their high and low sides are reversed.
2. Attach a BNC connector to one end of the remaining coax cable. Attach a
connector of your choice to the other end—this connector is to be either panel-
mounted or inserted through the antenna connector opening located at the center
of the back panel,
3. Mount the hex spacers to the Repeater bottom panel as shown in Figure 1, then
mount the duplexer on the spacers.
4. Attach the RF patch cables to the appropriate pot-Is.
5. Check Repeater performance.
NOTE: Be sure to perform ale—sense hefmg you install the Repeater at the selected
site. With the six-cavity duplexer installed, RRX—450 30 Watt Repeaters are
to have less than 2 dB of de—sense, more than 20 Watts of RF power and
more than 32 “V of RX sensitivity.
