Electromagnetic Interference/ Compatibility

NOTE: Nearly every electronic device is susceptible to

electromagnetic interference (EMI) if inadequately shielded, designed or otherwise conﬁgured for electromagnetic compatibility.

FACILITIES

To avoid electromagnetic interference and/or compatibility conﬂicts, turn off your radio in any facility where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy.

FIXED SITE

Transportable Repeater equipment is transported to and then set up at a ﬁxed location and operated as a ﬁxed control station or repeater. The antenna installation must comply with the following requirements in order to assure optimal performance and make sure human exposure to radio frequency electromagnetic energy is within the guidelines set forth in the above standards:

The antenna must be mounted outside the building.

ANTENNAS

Mount the antenna on a tower if at all possible. The lowest point of the antenna must be elevated a minimum of 10 meters above the ground. This may require the use of a coaxial cable extension for the antenna.

If the antenna is to be mounted on a building, then it must be mounted on the roof. If the antenna supplied with the repeater is used and the repeater cannot be located within the 12 ft. cable length, then a coaxial cable extension should be used.

As with all ﬁxed site antenna installations, it is the responsibility of the licensee to manage the site in accordance with applicable regulatory requirements and may require additional compliance actions such as site survey measurements, signage, and site access restrictions in order to insure that exposure limits are not exceeded.

Introduction

General

Compact Mechanical Design

State-of-the-Art Electrical Design

The Motorola PDR 3500 provides conventional analog, ASTRO™ ,

ASTRO CAI™ , and SECURENET™ capabilities in a compact,

software-controlled design. The station architecture and microprocessor-controlled Station Control Module allow for fast and reliable upgrading. FLASH memory in the Station Control Module allows software updates to be performed locally (using serial port), or remotely via modem.

The entire unit is housed in a lockable rugged, black aluminum extruded case weighing approximately 46 lbs. Internal components are mounted in a custom, removable chassis, designed to ﬁt a 19" rack.

Transmitter Circuitry

Receiver Circuitry

Station Control Module

The station transmitter circuitry is designed for 50% duty cycle operation at full rated power. Output power is continuously monitored by an internal calibrated wattmeter. The wattmeter output feeds a power control loop, continually adjusting and maintaining the desired output power. All adjustments are electronic, including deviation and output power.

The station receive circuitry features multiple bandwidth capability (12.5, 25, or 30 kHz, depending on band), as well as ASTRO digital operation. Injection signals for the 1st and 2nd local mixers are generated by frequency synthesizer circuitry and are electronically controlled by the Station Control Module. All receive signals (analog, SECURENET , ASTRO , and ASTRO CAI ) are detected and digitized before being sent to the Station Control Module; this provides improved audio quality, consistent throughout the coverage area.

The Station Control Module is microprocessor-based and features extensive use of ASIC and digital signal processing technology. The module serves as the main controller for the station, providing signal processing and operational control for the station modules.

System Applications

Local Control

The PDR 3500 is an APCO 25 digital repeater. The station is identical in operation to the Quantar station, hence there is no local control capability. There is no digital-to-audio translation within the station. Local control style operation can be accomplished in several ways:

a. A portable radio may be used as an RF control station talking to

the repeater.

b. The station may be equipped with the wireline and the modem

options and routed through a DIU to a tone remote console. The Tone remote console controls the station via wireline through the DIU. The wireline in this case is a local 4-wire cable.

External Duplexer Operation

Repeater RA or Cross Band Repeater Operation

The PDR 3500 must be used with an external duplexer when frequency spacing is less than 3 MHz. The duplexer isolation required for proper operation is approximately 60 dB. Doubleshielded coaxial cables must be used from the repeater to the duplexer.

The PDR 3500 can be conﬁgured for Repeater RA or cross band repeater operation by adding the wireline card and the Astro modem to the each repeater. The repeaters are connected together using the wireline port on each repeater. The cables are terminated in RJ-45 connectors.

Setup and Connections

Programming with RSS

Introduction

Connecting PC to PDR 3500 RSS Port

The PDR 3500 uses the same RSS (Radio Service Software) as the Quantar/Quantro family. Some values shown in RSS screens may not be valid due to hardware differences between the Quantar Station and the PDR 3500. A thorough explanation of the differences will be given in the following sections.

Once the RSS Program has been loaded onto the PC (refer to

Quantar RSS User’s Guide , 68P81085E35), the PC must be

electrically connected to the PDR 3500 via the RSS port located on the top panel. For this connection, a 9-pin female to 9-pin male EIA232 cable is available (Motorola part number 30-80369E31) from the Accessories and Aftermarket Product Division (AAD, formerly known as Motorola National Parts). A cable can also be made using the wiring diagram in Figure 1.

Connect one end of the cable to COM1 on the PC and the other end to the 9-pin connector labeled “RSS” on the top panel of the PDR 3500.

Using the RSS

Status Panel

For information on starting the RSS, conﬁguring screen colors, setting up the PC serial port, and general RSS use, refer to the

Quantar RSS User’s Guide (68P81085E35).

The “Status Panel” screen in the RSS can be used to change the channel of the PDR 3500, view parameters for the current channel, and view the status of several station functions.

From the Main Menu, press “F2-Service.” Next, press “F6-Status Panel…” and then F2 again to arrive at the Status Panel display.

The Status Panel shows the current channel number and the Transmit and Receive frequencies for the current channel. In the middle of the screen, the states of several station components are shown, mirroring LED indicators on the front of the station modules. For the PDR 3500, the “AC” ﬁeld indicates whether the station’s internal DC voltage is above the threshold required for full transmit power. Near the bottom of the screen, the most recent status message is displayed.

NOTE: The date and time of the status message will be

incorrect if the station has lost power since the internal clock was last set.

Hardware Conﬁguration

The current channel can be changed by pressing F2 to increment the channel number and Shift+F2 to decrement the channel number. Other available commands are listed in the soft menu at the bottom of the screen and include resetting, access-disabling, and keying/ dekeying the station.

For a complete description of the Status Panel ﬁelds and commands, please refer to the Quantar RSS User’s Guide (68P81085E35).

From the Main Menu, press “F2-Service.” Press F2 again to arrive at the Hardware Conﬁguration screen.

1. The ﬁrst ﬁeld to verify is the Hardware Platform ﬁeld. The PDR 3500 is designed using the Quantar proﬁle and will not operate properly in any other mode.

2. The next ﬁeld to verify is the System Type ﬁeld. This ﬁeld should be set to “Conventional.” The PDR 3500 does not operate as an ASTRO-TAC Receiver or DBS Base Station.

7-2 68P81093C75-A

3. Next verify that the Rx Freq Band 1 and Tx Freq Band ﬁelds list the correct ranges for receiver and transmitter.

NOTE: Rx Freq Band 2 should be set to “NONE.”

4. The PA Power Rating ﬁeld should be set based on Table 5. All PDR 3500 transmitter ranges except UHF R3 and R4 use the Quantar low-power station proﬁle. However, there is no lowpower UHF R3 or R4 Quantar, so the high-power proﬁles are used for those ranges.

Table 5. RSS Settings for PA Power Rating

Transmitter Band RSS PA Power Rating

VHF R1 (5-30 W) VHF R2 (5-30 W) UHF R1 (5-30 W) UHF R2 (5-30 W)

UHF R3 (5-30 W) 110 Watts

UHF R4 (5-25 W) 100 Watts

800 MHz (5-22 W) 20 Watts

25 Watts

NOTE: Since high-power Quantar proﬁles are used for UHF

R3 and UHF R4 PDR 3500’s, which put out 30 and 25 watts respectively, Table 6 must be used to translate from actual power output to the power levels speciﬁed in RSS. In particular, the table must be used for Power Out alignment and conﬁguration of Channel Information . The table is located in the

Alignment section of this manual.

5. Check that the Power Supply ﬁeld shows “AC HIGH.” This setting remains the same regardless of whether the PDR 3500 is running off of AC or DC power.

NOTE: Older units may require the Power Supply ﬁeld to be

set to “AC LOW.” If this is the case, the station will report a mismatch when validating the hardware conﬁguration as described below. If such an error is reported, change the Power Supply ﬁeld to “AC LOW” and repeat the validation.

6. If the unit is equipped with a Wireline Card, verify that the

Wireline ﬁeld is set to “4-WIRE” or “8-WIRE” as appropriate.

Once the Hardware Conﬁguration screen matches the installed station hardware, press F8 to validate the conﬁguration. A popup message will notify the user of any errors in the conﬁguration. For a complete description of the Hardware Conﬁguration ﬁelds, please refer to the Quantar RSS User’s Guide (68P81085E35).

68P81093C75-A 7-3

Channel Information

From the Main Menu, press F4. Press F4 again to arrive at the Channel Information Screen. From this screen, the user may conﬁgure the TX and RX frequencies, RF power out, modulation type, and the various channel traits for up to 16 channels.

1. In this screen, ﬁrst set the Rx1 and Tx frequencies to the proper values.

NOTE: The Rx2 frequency is set to 0.00000 MHz and cannot

be edited. This is because the PDR 3500 does not support 2 receivers.

The station will automatically calculate the Tx Idle Frequency based on the TX-RX spacing for the channel. In most applications, the TX Idle Frequency will be the same as the Tx Frequency. However, in case of portable or mobile radios unsquelching near the PDR 3500, adjust the Tx Idle Frequency to the Tx Frequency -6.25kHz.

2. Set the modulation type to either Analog, ASTRO, ASTRO CAI, Analog/ASTRO CAI, or CAI RX WIDE DEV.

3. Move to page 2 of the Channel Information Screen by pressing the Page Down key. Set the Normal Tx Power Out to the desired power level, unless the station being programmed is UHF R3 or UHF R4. If the station transmitter is UHF R3 or UHF R4, the power output must be translated using Table 6 due to a difference between the power range in RSS and the actual power range of the station.

All bands except UHF R3 and UHF R4 use the low power Quantar station proﬁle, meaning the station is RSS programmed as a low power station, and the actual output power of the station matches what is programmed in RSS. For UHF R3 and UHF R4, however, there is no low power Quantar proﬁle, so the high power proﬁle is used. Thus, all power settings in RSS for those bands are based on a range of 20-120W for R3 and 20-110W for R4. Since the actual output power of the PDR 3500 is 5-30W for R3 and 5-25W for R4, Table 6 must be used to translate actual power into RSS power. The “Actual Power” column corresponds to the power out of the PDR 3500 while the “RSS Power” column corresponds to power levels to be entered in RSS during the alignment process.

For example, to set a UHF R3 station to transmit at 15 watts, “60” should be entered in the Normal Tx Power Out ﬁeld of RSS, as speciﬁed in Table 6.

4. The Battery Backup ﬁeld speciﬁes the output power of the station when a low DC supply voltage is detected by the station. This ﬁeld is intended primarily for use in DC-powered applications such as running off a car battery.

The Battery Backup setting should be 10 watts or less and should typically be lower than the Normal setting. The station will switch from the Normal to the Battery Backup power setting when A+ on the backplane drops below approximately 12 volts for UHF R4 or approximately 11 volts for all other ranges.

NOTE: Because the PDR 3500 can draw up to 10 amps

during high-power transmission, there can be a signiﬁcant drop in voltage through a DC power cable. If the station reverts to low-power mode while operating off of DC, a shorter DC cable may help.

5. In DC-powered applications, the Over Air and Over Wireline

Alarm Tone ﬁelds specify whether the station will transmit an

alert tone when a low-voltage condition is detected. Setting either of these ﬁelds to “ENABLED” will cause the station to periodically transmit a beep via that path (air or wireline) while operating at the Battery Backup power setting. See the

Interpreting Alarm Tones heading of the Troubleshooting

section of this manual for more information.

Alignment

For a more complete description of the Channel Information ﬁelds, please refer to the Quantar RSS User’s Guide (68P81085E35).

From the Main Menu, press “F2-Service.” Now press “F3” to arrive at the Alignment Menu. From this menu, the user may align the RF Power Out, RSSI, Station Squelch, and BER. Before performing any alignments, at least one channel must be programmed as described under the Channel Information heading.

For instructions on performing Rx or Tx Wireline Alignment, please refer to the Quantar RSS User’s Guide (68P81085E35).

NOTE: Before performing any alignment procedures, ﬁrst

dekey the station and “Access Disable” the repeater as shown in Step 1 below.

1. Access Disable :

1. From the main menu, press “F2-Service.”

2. Press “F6-Status Panel/Software Ver/Set Date and Time.”

3. Press F2 to arrive at the Status Panel Display Screen.

4. From this screen, press F6 to activate the Access Disable function. In this mode, the station will not keyup in response

7-6 68P81093C75-A

to a received signal. To deactivate the Access Disable function, press shift+F6.

2. RSSI Calibrate :

1. In the Alignment Menu Screen, tab over to the RSSI

Calibrate ﬁeld, and press F2 to perform the alignment.

2. Using an R2670 or equivalent Communications System Analyzer, connect the RF out from the Analyzer to the Rx UHF-type connector on the station top panel.

3. Set the RF output level from the Analyzer to –90 dBm with no modulation, and set the frequency to PDR 3500 receive frequency.

4. With the Analyzer RF turned on, make sure the value shown in the RSS screen is –90 dBm. If it is not, type in “–90 dBm.”

5. Press F8 to save the calibration.

3. Power Out: The output power of the PDR 3500 is aligned to a predetermined

reference level near the upper limit of the station. This level is the same irrespective of the desired output power of the station, and is speciﬁed for each frequency band based on Table 7.

Table 7. Alignment Power by Frequency Band

Frequency Band Rated Power Alignment Power

VHF R1, VHF R2 30 W 25 W

UHF R1, UHF R2 30 W 25 W

UHF R3 30 W 27.5 W (110 W in RSS)

UHF R4 25 W 22.8 W (100 W in RSS)

800 MHz 22 W 20 W

The power output alignment process is basically a feedback loop: The station attempts to transmit at the alignment power level from Table 7. The user checks the power on a wattmeter and tells the station what power it is actually putting out. The station then adjusts its output power to get closer to the alignment power. This process is repeated for the desired level of accuracy.

1. In the Alignment Menu Screen, tab over to the TX Power ﬁeld and press F2 to perform the alignment.

2. For this procedure, connect the TX UHF-type connector on the station top panel to the RF input of either a Motorola

68P81093C75-A 7-7

R-2670 Communications Analyzer, or to the input of an RF power meter. The duplexer is bypassed for this

alignment.

3. Press F6 to keyup the station.

4. Check the output power level shown on the R2670 or RF power meter.

5. Press F9 to dekey the station.

6. Enter the power from the meter in the ﬁeld shown in RSS, or for a UHF R3 or UHF R4 station, enter the translated RSS Power from Table 6. See the Channel Information heading and Table 6 for more information on power translation.

7. Press F7 for the PDR 3500 to adjust the PA power output level.

8. Once the unit adjusts the power (about 2 seconds), again keyup the station and read the RF power from the meter, then dekey the station.

9. Repeat steps 3 through 8 until the power output is as close to the alignment power from Table 7 as possible. If the power output will not adjust properly, press F4 to initialize the PA and restart the alignment procedure.

10. Press F8 to save the settings to the station codeplug.

11. Exit the Power Alignment screen by pressing F10, then key the station using the top-panel PTT switch. Verify that the power being put out is what is programmed in the station codeplug.

NOTE: It is not necessary to dekey the station after each

power reading, however if the station is keyed continuously it must periodically be given time to cool to ensure proper alignment. If at any point the station has remained keyed for over 1 minute, it is recommended to dekey it and allow it to cool for approximately 30 seconds before continuing with the alignment procedure.

4. Squelch :

1. From the Alignment Menu, tab over to the Squelch Adjust ﬁeld and press F2 to perform the alignment. The Squelch control bar is shown in the center of the screen.

2. To open the squelch completely, press F2. To close the squelch completely, press F4. To adjust the squelch between fully open and fully closed, use the Pg Up/Pg Dn keys on the PC.

Introduction

Separate RX and TX Connectors

Duplexer

The transmit and receive antenna RF connections may be made in one of two fashions depending on the system application.

Separate TX and RX antennas. The PDR 3500 top panel has two UHF-type connectors: one for

RX, and one for TX. In this conﬁguration there is a separate antenna for each connector.

Duplexer Using this conﬁguration, only one antenna is required for both

transmit and receive. The duplexer is mounted to the station top panel and has a single N-type connector for the antenna. An N-to-UHF adapter is provided.

In order to use two antennas, ﬁrst disconnect the duplexer cables (if equipped). Connect the Rx antenna to the UHF connector labeled “RX” on the top panel, and the Tx antenna to the UHF connector labeled “TX” (Figure 2).

The duplexer allows the PDR 3500 to use a single antenna for both transmit and receive.

1. Connect the UHF connector labeled “RX” on the station top panel, to the N-type connector labeled “RX” on the duplexer.

2. Connect the top panel UHF connector, labeled “TX,” to the N-type connector labeled “TX” on the duplexer.

3. Connect the antenna UHF-type connector to the connector labeled “ANT” on the duplexer.

NOTE: To assure optimal performance and that human

exposure to radio frequency electromagnetic energy is within guidelines, the antenna should be mounted as described in Section 2, Safety and General Information, under Fixed Site Antennas.
