1.6 Radio Series I or II
System-engineered installations use one of two
complements of ParagonPD radio modules. They
are assembled on a common chassis:
Series I models:
- 800 MHz frequency range radios
- Frequency programming is done via
EPROM. (This model does not use the pro-
gramming port of Series II models).
Series II models:
- VHF and UHF frequency range radios (800
MHz models will be available as Series II at
a later date)
- Frequency programming is done using soft-
ware via a programming port located on the
speaker front panel.
1.7 Packaging
Each ParagonPD product normally leaves the
factory packaged as follows:
• A Series I or II Dataradio base station “Ra-
dio assembly”
• A dual power supply assembly
• A Dataradio BDLCPD model
• A Radio Interface Cable to link the Radio
assembly to the BDLCPD:
18-inch long “Y” cable; DB-25 female to
dual DB-25 female (p/n 730 03374-102)
for connection between backplane PCBs
and BDLCPD.
• One standard seven-foot 120VAC power
cord
• Two DC power cables to connect the radio
assembly to the dual power supply assem-
bly.
• Courtesy small parts kit
Frequently, ParagonPD product components are
field-assembled prior to customer delivery.
The cabinetry may then be supplied in one of
several custom rack-mount configurations that
may also include fan, backhaul modems,
duplexer/filters/combiners, and ancillary
equipment.
If damage has occurred to the equipment during
shipment, file a claim with the carrier immedi-
ately.
2. Installation
2.1 Overview
The cabinet and rack-mount housing the Para-
gonPD’s Radio assembly and the BDLCPD is gen-
erally installed in a sheltered facility. Occasion-
ally located adjacent to the nerve center of the
user’s network, it is often located near tower
sites or at remote locations where it operates
unattended.
Furnishings needed include power, cabling and
installation of antenna, landline or microwave
modem and host PC or portable computer. De-
tails of these are outside the scope of this man-
ual. This manual covers the radio assembly and
the BDLCPD that includes the modem.
2.2 Location
Be sure to place the ParagonPD in such a way
that:
• The LEDs can be seen (as an aid in trouble-
shooting)
• Access to the antenna connector and to the
back connectors is possible without remov-
ing the unit
• Sufficient air may flow around the unit to
provide adequate cooling.
2.3 Electrical
Standard 120 VAC electrical power is required.
It should be capable of providing at least 10A.

2.3.1 Radio Assembly Power
Referring to Figure 3, the Radio assembly unit
receives two separate 13.8 VDC power inputs
from a “T800 Slimline” dual power supply typi-
cally rack-mounted right below the main assem-
bly radio chassis.
The T800 is made up of two separate power
supply units joined in a single chassis:
• A T807 using convection cooling is rated up
to 15A. It supplies all the radio modules
other than the Power Amplifier.
• A T808 using convection and fan cooling is
rated up to 25A. It supplies only the Power
Amplifier module.
Normally used at room ambient temperatures,
they can operate within specifications over a
range of –10 to +60 °C.
Note: Internal over-temperature protection
shuts down the main transformer above
105 degrees Celsius.
Both power supply modules are internally con-
nected to ground via their individual, rear-
connected, seven-foot standard 120 VAC power
cords. Nevertheless, each requires a separate
secure electrical ground connection. Individual
grounding tabs are provided next to the power
connectors.
Similarly, the Radio Assembly chassis requires a
secure ground connection. A threaded grounding
binding post fitted with a knurled binding-nut is
provided on the chassis next to DC input 2.
Separate grounding leads with appropriate con-
nectors are supplied (either in the courtesy
small-parts kit or with one end fastened to the
equipment.
A- For each of the power supply modules:
1. Fit one end of the grounding lead’s
push-on connector onto the ground-
ing tab.
B- For the Radio Assembly chassis:
1. Install the grounding lead’s lug over
the binding post and firmly hand-
tighten the binding-nut.
For both A and B
2. Fit the slotted connector (on the other
end of each of the grounding connector)
under a conveniently located screw on
the rack frame or other support surface.
Scrape away paint if needed to ensure
clean contact.
3. Apply anti-corrosion compound where
paint scraping was done.
4. Ensure by testing continuity that a se-
cure electrical and mechanical connec-
tion is achieved.
If a –DC rail (0V) is installed as part of the sys-
tem, the grounding leads may alternatively be
fitted to the rail terminal.
Caution:
Improper grounding between power
supply case and rack frame may result
in harmful voltage potentials and/or
miscellaneous power supply switching
noise problems in both receivers and
transmitter.
Press both red power buttons located on the front
of the module to have complete power distribu-
tion to the Radio assembly.
The power supply front panel LEDs indications
are:

The Radio assembly is fused at the rear of the
chassis:
• Fuse 1 is a 32-volt MDL (slow-blow) 10A
• Fuse 2 is a 32-volt MDL (slow-blow) 30A
120 20170-200 ParagonPD Technical Manual8
2.3.2 BDLCPD assembly Power
The BDLCPD assembly uses a standard 120
VAC power cord. Plug this cord to the rear
power outlet shown in Figure 6.
To check or install a fuse:
1. Open the slide-out fuse drawer located be-
low the power connector.
2. Use a fine bladed screwdriver or a knife
blade and gently pry open.
3. Hold the fuse support in one hand and with
the other, lift the center plastic retainer until
it releases the fuse sliding base.
4. Replace or install a 250V, 2A fuse.
5. To complete the procedure, push the sliding
fuse base until it snaps under the retainer.
6. Re-insert the fuse drawer in its housing and
push until it is fully seated and closed.
When ready to apply power, use the ON-OFF
toggle power switch adjacent to the power con-
nector.

2.4 Antenna
2.4.1 Overview
ParagonPD commonly uses three antennas (one
transmit and two receive) unless a duplexer is
used with one of the receive antennas; then only
two antennas would be needed. They should be
mounted according to any guidelines supplied
with the antennas. For antennas placement and
spacing, consult System Engineering.
2.4.2 Cabling and Connection
1- Route good quality 50-ohm double-shielded
coaxial cable(s) (e.g. RG-214 or Heliax)
from the selected antenna position(s) to the
ParagonPD Radio assembly.
2- Terminate the RX-1 and RX-2 cable ends at
the Receiver modules rear position with an
N-type connector.
3- Similarly, terminate the TX cable end at the
Power Amp’s module rear position with an
N-type connector.
Caution:
When terminating RF cables
use brand-name crimping tools
(such as AMP, Jensen, Crimp-
Master, etc…) of the correct
size for the cable and type of
connector used.
Common pliers are NOT ac-
ceptable.
2.5 Completing the physical
Installation.
ParagonPD products are factory-configured to
user’s requirements and are shipped ready to
run.
After new installations:
• Re-check that all connections are secure on
radio and BDLCPD assemblies (antennas,
PC, power cords etc.)
• Check that fuses are inserted.
• Turn both BDLCPD and radio power ON.
You are now ready to check for normal opera-
tion and to run the Radio Installation Software
(RIS) program for testing or trouble-shooting.
Any change(s) to the settings must be done via
files saved on diskette and loaded into the unit
using the RIS program.

2- Check Radio assembly lights for proper op-
eration as per section 3.1.1
3- Check for proper operation of the BDLCPD’s
LEDs as per section 3.2.1.2.
4- Using the RIS program (described in section
4), and an in-line wattmeter, check forward
& reflected power to confirm antenna in-
stallations.
5- Using the RIS, check the RF link with a mo-
bile station that can be heard, by using the
RIS “Ping” feature. See section 4.4.4.3
If user application and a mobile station are
available, test the installation by going through a
normal sequence of transmitting and receiving
messages.

tion to the Radio assembly
• Two “ON” LEDs - light green when push
button is ON; DC power is distributed to ra-
dio modules. Flash green in conjunction with
the “OL” LED when an over voltage condi-
tion is present.
• Two “Stby”- Standby voltage LED, lights
red when push button is off; AC power is
applied but DC is not distributed to radio
modules. To remove presence of voltage,
disconnect both power cords.
• Two “OL” LEDs - Monitor current overload,
light red when supply exceeds current limit
set; nominally 25Amps (T808 model).
Flashes red in conjunction with the ON LED
when an over current condition is present.

3.2 BDLCPD
The rack-mounted BDLCPD is housed in a steel
case. It has no user serviceable parts. Unit’s con-
figuration is stored in flash memory (EEPROM).
3.2.1 BDLCPD Front panel
Referring to Figure 2, the front panel of the
BDLCPD has two cutouts across its length.
A- The left cutout groups the unit’s type label
and ten LED indicators:
• The S3 label designates the BDLCPD as a
“three Serial-port” model
(Ports 4 and 5 are reserved for future use)
• The RF group of 3 LEDs
• The RS-232 group of 5 LEDs
• A single CK LED
• The ALARMS group of 4 LEDs
B- The right cutout groups two tactile (mem-
brane) switches (PF1 and RESET).
3.2.1.1 Front Switches
Referring to Figure 11, the BDLCPD uses two
membrane-type switches labeled:
• RESET
• PF 1
These switches indicate contact by emitting a
short BEEP tone when pressed.
Figure 11 - BDLCPD membrane switches
3.2.1.1.1 Reset
Pressing Reset produces the same result as pow-
ering OFF and ON again. It restarts the micro-
processor, the peripherals and invokes the on-
board diagnostics. BDLCPD’s radio modules’
internal flash-memories are read and their values
are loaded in system SRAM CPU flash-memory.
Normally, pressing Reset results in one short
BEEP tone followed by all LEDs coming ON for
about four seconds. Then, the LEDs flash in a
“ripple” pattern for close to two seconds indi-
cating diagnostics are in progress. At the end of
this period, all LEDs should be OFF except CK
that should flash about six to eight times per
second.
Expect an additional two seconds delay for CK
to start flashing and the UF indicator to come
ON if the radio assembly is not connected or not
powered (see section 3.2.1.2.4 for Alarm de-
tails).
3.2.1.1.2 PF 1
PF 1 is a multi-function switch:
• It clears LED error indications
• It initiates test transmissions
• It sets the function of the RS-232 LEDs
PF1 RESET
120 20170-200 ParagonPD Technical Manual13
3.2.1.1.2.1 Clearing Errors
Major and minor error LED indications remain lit
on the front panel until:
• The unit is RESET
• The unit is powered OFF and ON again
• PF 1 is pressed
The PF 1 switch can be pressed at any time to
clear an error display without affecting normal
operations.
3.2.1.1.2.2 Test Transmissions
To select a pattern and begin transmission, start
by pressing and holding PF1. It beeps once, all
five RS232 LEDs light; listen for a second beep
followed by a third beep. After two seconds, the
unit beeps and goes in “TX Select” mode with
only the three rightmost RS-232 LEDs now used
as selection indicators. Only release PF1 after
the third beep.
Following release:
• Start of selection must be made within two
seconds. If not, the unit will default to pat-
tern one and start test transmitting.
• PF1 may be pressed more than once. The
number of times it is pressed determines the
type of pattern that will be transmitted ac-
cording to Table 3
• Each pressing of PF1 extends the two-second
timer.
• The three rightmost RS-232 LEDs display
are used to indicate TX mode selection as
shown in Table 2.
Table 2- TX mode selection LEDs indications

selected FT LED RD LED TD LED
1 Off Off On
2 Off On Off
3 Off On On
4 On Off Off
5 On Off On
6 On On Off

Once the type of transmission is selected, stop
pressing PF1, allow the two-seconds timer to run
down. Automatically, the BDLCPD turns its
transmitter ON, sends the selected “test pattern”
for 55 seconds and turns its transmitter OFF.
The TX LED in the RF group of indicators lights
in red while test transmitting. Pressing PF1 while
the 55 seconds test is in progress stops the test.
At the end of test transmission, BDLCPD opera-
tion returns to normal and the RX LED lights in
green (monitoring normal transmitter activity).

Press PF1 to terminate beacon mode.
3.2.1.1.2.3 RS-232 LED Function
Selection
The PF 1 button is used to select the RS-232
display mode as follows:
• If pressed ONCE (do not hold pressed):
- Clears Alarm indications
- CK LED stops flashing for 2 seconds
- During this time, one or all of the
RS-232 numbered LEDs (see Figure 13)
will light. If one LED lights, it denotes
the port to which the subsequent display
applies. If all numbered LEDs light, it
denotes that the normal 3-port display
mode is active.
The selected display remains active until
120 20170-200 ParagonPD Technical Manual14
manually changed or until RESET is
pressed or until power up.

• If, during the 2 seconds period that CK is not
flashing, PF 1 is pressed a second time, the
LED functions will advance one step from
top to bottom through the available options
in the order shown in Table 4.
• PF 1 may be pressed repeatedly during the 2
second period (extended with each press) to
advance to the desired numbered LED func-
tion option.
Once the desired RS-232 LED function is se-
lected, stop pressing PF1, allow the two-seconds
timer to run down. The BDLCPD returns to nor-
mal operation using the newly selected display.
3.2.1.2 LEDs and Indications
LEDs are used to indicate the operation status of
the BDLCPD. Although capable of displaying
three colors, only the green and red colors are
used for the BDLCPD. They are grouped by their
function:
• RF Group, displays radio channel status in
green
• RS-232 Group, displays serial port status in
green except the TX LED that also uses red
• ALARM Group, displays fault status in red
3.2.1.2.1 Radio Network Indicators
The Radio Network LEDs are useful when trou-
bleshooting as an indication of network activity.
It can help isolate transmission problems.
Figure 12 - RF indicators
CS Carrier Sense - Steady light indicates
that an incoming radio data signal is be-
ing detected by the DSP modem. CS
signal is not user-adjustable.
RX Receive Data – Flashing light indicates
unit is internally receiving data from the
radio network.
TX Transmitter ON – blinks green indicates
(depending on display mode selected):
• That a data packet or ACK (packet
acknowledgment) is being
transmitted.
• That an idle packet, data packet or
ACK is being sent. Test transmis-
sion display is done in red.
3.2.1.2.2 RS-232 Port Indicators
The RS-232 LEDs normally indicate port activ-
ity on the port selected. See section 3.2.1.1.2.3
above for instructions for selecting display
mode.

FR Flow Control on Receive - the BDLCPD
has received a flow control signal from
the device connected to it. When it
lights, BDLCPD has stopped sending data
to the DTE. When LED goes out, the
port terminal is again ready to receive
data.
FT Flow Control on Transmit - the BDLCPD
has sent a flow control signal to the DTE
asking it to stop sending data. The LED
remains lit as long as the terminal is be-
ing held off.
RD Receive Data - when lit, it shows that the
Receive Data pin 3 on the RS-232 inter-
face connector is active. Since all
BDLCPD are configured as DCE, it
means that the DTE is receiving data
from the BDLCPD.
TD Transmit Data - shows the status of
Transmit Data pin 2 of the RS-232 inter-
face. When lit, the DTE is sending data
to the BDLCPD.
3.2.1.2.3 Check and Power
CK Check:
Normally flashing rapidly (about 6 cps),
indicates microprocessors are working
correctly and power is applied.
Not flashing indicates unit is not func-
tioning.
Blinking slowly (1 cps), indicates the
parameters contents of the flash memory
have been corrupted. The unit automati-
cally loads its set of factory default pa-
rameters and starts beeping at 20 sec-
onds intervals.
May also indicate DSP-modem re-
initialization has occurred
3.2.1.2.4 Alarm Indicators
All alarm conditions will cause the BDLCPD to
light one or more of the LED indicators. LEDs
remain ON when lit until cleared by either
pressing PF 1 (without affecting operation of the
unit) or RESET (cycling unit OFF and ON).
Figure 14 - ALARMS LED indicators
LM Local Minor Alarm - when lit, indicates
the presence of any of the following mi-
nor faults:
- Parity, framing or overrun error at any
RS-232 port.
- Out of buffers. No memory available
to accept data from a local terminal de-
vice. Usually denotes a flow control
problem.
- Flash memory error. At power-up or
reset, the unit detected a change in non-
volatile memory.
RM Remote Minor Alarm - when lit, indi-
cates any of the Local Minor Alarm
listed above have taken place at the re-
mote end of the link (i.e. the mobile the
local base station is currently communi-
cating with). It will also light when a
protocol error has been detected on the
network.
In a network using the “Host Link Ac-
tive” (MSC) feature, the RM LED,
flashing in-sync with the CK LED, indi-
cates that the link is down.
ALARMS
LM RM LF UF
120 20170-200 ParagonPD Technical Manual16
LF Link Failure - when lit, indicates that the
base station fails to receive an ACK for
a packet sent and for all subsequent re-
tries. Some data has possibly been lost.
LF is not functional if all active ports are
set to NAR mode.
Link fails are inevitable during normal
operation (mobiles temporarily out of
range, in a tunnel, parked in a dead spot,
etc.). A lit LF LED is not normally
cause for concern.
UF Unit Failure - when lit, the unit requires
attention:
- the BDLCPD is not operable;
It may indicate detection of a system
software error trap.
- the BDLCPD is operable;
Indicates that on power-up, invalid data
was detected in the serial EEPROM chip
(located in the radio modules). It may
also indicate that connection to the radio
modules is incorrect or that radio power
is not applied.
The LM, RM and UF alarms also sound a beep
when a fault occurs. The LF alarm is silent.
3.2.2 BDLCPD Rear panel
Referring to Figure 4, the rear panel of the
BDLCPD has the following set of chassis con-
nectors:
• Four DE-9F connectors:
– DEV2 - usually connected to Datara-
dio’s RIS program (DMP/Setup 19200).
Can also be used with special user’s ap-
plication such as telephone modem
Note: connection to a telephone re-
quires the use of a DCE Crossover ca-
ble.
– DEV3 - Dedicated (9600)
– DEV4 and DEV5 - not used
• One DB-25F connector
- DEV1 - Connects to user’s application.
a) DMP 19200 for single-site installa-
tions

4. RIS program
The Radio Installation Software (RIS) program is
used to:
• Check and troubleshoot ParagonPD.
• Save an existing configuration.
• Upload files for field configuring of units
(Requires intervention with technical sup-
port).
Important note:
The aggregate total baud rate for all active
ports on a BDLCPD must not exceed 30,000
for ParagonPD. Sustained simultaneous op-
eration on devices 1 and 3, using the fac-
tory settings for these ports, may result in
lost characters.
Using the factory settings, device 3 is in-
tended only for use during configuration and
should not be used simultaneously with data
traffic on device 1. For special user applica-
tion done while the BDLCPD is active, use
either device 2, or set device 3 to 2400
bauds.

4.4.3 Special Functions
The following RIS fields and buttons are used to
gather specific information concerning the con-
nected BDLCPD:
• Banner field
• “i” button
• Comments field and Put Comments button
• Password and Put Password button
4.4.3.1 Banner Field and “i” button
This field displays a string made up of the serial
number of the connected unit followed by the
firmware(s) used and their version number.
Format For ParagonPD model is:
[on-air address]:firmware 1 name, its version #,
firmware 2 name, its version # (where name 1 is
for DSP and name 2 is for the main cpu).
ParagonPD's firmware(s) resides in flash
EPROM and are designed to allow field up-
grades.
When contacting your supplier, give the full ban-
ner string and the version of the RIS used. You
will find the version number in the “About” win-
dow. To open it, click the lower left square but-
ton (with a lowercase letter “i” in it).
The Banner field is blank prior to establishing a
link with the equipment using the Connect button.
4.4.3.2 Comments

word” field. It is a string of 32 hexadecimal
characters (exactly).
2- Press the button “Put Password” to make the
entry permanent. This field may be left
blank.
On subsequent Connect, this field will require
that the correct password be entered. If none was
entered, the field will remain blank.
Password information is NOT retrieved and
saved to a file, along with the configuration.
Clearing a Password is done by entering 32 zeros.
The Dataradio supplied password algorithm is
designed to thwart the casual observer only. It
provides a limited form of data privacy. There-
fore, if your security requirements are high, Da-
taradio urges you to use external encryption
technology such as Data Encryption Standard
(DES) in the Host and Mobiles computers.

address selected, the status bar displays:
• “Ping Successful” and pinging stops.
• If no ping signal is received after 60 sec-
onds, ping testing stops and the status bar
displays “Ping Failed”.
4.4.4.4 Ping addresses
Addresses may be entered by typing directly in
the “Ping Address” field as an “Alpha-Mapped-
Nibble” (AMN) address for mobiles, consisting
of upper case letters in the range A-P. The valid
address range is A to GN (8 characters max.).
The program may display one of the following
messages on the status bar:
“Ping address is not in AMN or number format”
or
“Ping address is not in the range A – GN”
In either case, check that the address entered is
within the acceptable range, is of a valid format
and correctly typed.
4.4.4.5 Flatness test button
This complimentary feature has been added to
support the ParagonPD radio’s low-frequency
balance adjustment.

5. Testing and Trouble-
Shooting
The checks described below should be done at
time of installation, annual intervals or whenever
deterioration in performance is noted.
5.1 Equipment Required
• In-line watt meter (150W & 10 W ranges)
• Radio service monitor (IFR-120B with op-
tion 03: 30KHz IF filter or equivalent).
• RG-214 or RG-223 cable with N-Type male
connector to connect ParagonPD to the serv-
ice monitor.
Important note: Before proceeding make sure
that the service monitor has been calibrated
recently and has warmed up for at least the
time specified by its manufacturer.
Some reported frequency and deviation problems
have actually been erroneous indications from
service monitors that have not adequately
warmed up. This is particularly likely when field
service is done during winter months.
5.2 Recommended Checks
A) After an installation
1. LED Indications
2. Save “unit config” to a file

6. Radio Programming and Adjustments
All receiver procedures detailed in this section should be done twice: once for the main receiver module
and a second time for the second receiver module. Connect to the relevant module and its corresponding
backplane PCB as required.
Both Series of ParagonPD radio module assemblies share the same backplane PCBs. Refer to section
3.1.2.1 for details. Programming for Series I is done via EPROMs while Series II uses of the RJ11 con-
nector present on the front of the Speaker panel and mirrored on both backplane boards (see section 6.3
below).
6.1 Series I 800MHz Radio Programming
This procedure describes the steps needed to program the ParagonPD’s Tait T800 Series I radio (half &
full channel) used in all ParagonPD 800 MHz versions. This procedure is a supplement to the Tait pro-
gramming procedure.
6.1.1 Recommended Items
T800win programming kit for Series I:
- PGM800Win programming software user's manual
- PGM800Win Windows based programming software
- EPROM Programmer BP MicroSystems’s model CP-1128 (suggested model)

and the receiver antenna connector.
b) Select the generator mode (GEN button) and set to the main receiver channel frequency
c) Select and turnon GEN2
d) Set the FM Deviation to ±3kHz (full channel) or ±1.5kHz (half channel) using 1 kHz sine
e) Select SINAD meter
2) Monitor the SINAD by connecting an X1 scope probe to the Demod O/P test point (close to
PL103 in the first section from the module front panel) or on the relevant backplane board at SK1
pin 6 (see Figure 30 for test point location).
3) Adjust the helical resonators #H1 to #H3 for best SINAD.
4) Continually decrease the RF level to reach 12dB SINAD, then re-do steps 3) and 4) again. (mini-
mum requirement to reach is 12 dB SINAD for –110 dBm)
5) Perform the SINAD linearity tests described in the next paragraphs below. If it fails to pass the
requirement, contact your Dataradio technical support.
120 20170-200 ParagonPD Technical Manual34
WARNING: Do not attempt to re-tune the IF stages (i.e. L312 to L318).
These adjustments do not need to be re-adjusted after frequency re-programming.
Touching these coils will have a direct impact on the DSP modem coefficient settings
and may significantly reduce the radio performances over data.
6.2.2.4 SINAD and Linearity Check
1. Apply the following settings to the IFR:
- Generator mode, Output T/R
- IFR TX frequency to match the main radio RX frequency
- Filter set to wide band (no audio filter)
- Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off, except for “wide-
band”.
- Set deviation to ±3.0KHz for full channel or ±1.5KHz for half channel radios.
2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm (including
cable loss).
3. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) above the main radio RX
frequency, record the SINAD reading. It should remain within 1.5dB from the on frequency
SINAD reading.
4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main radio RX
frequency, record the SINAD reading. It should remain within 1.5dB from the on-frequency
SINAD reading.
Note:
If one of the above requirements is not met, try to re-tune the front-end. If it is still “failed”,
contact your Dataradio technical support.
6.2.2.5 RSSI Adjustment
Note: This check is only recommended for ParagonPD model running DBA protocol 3.06.009 series or
later.
1. Apply an on-channel signal from the RF generator at a level of -110dBm with deviation of ±3kHz
(full channel) or ±1.5kHz (half channel) at 1kHz tone.
2. Adjust RV301 (RSSI level) to give 2.0V RSSI output when measured with a multimeter at SK301
pin 2 or on the relevant backplane board at SK1 pin 5 (see Figure 30 for test point location).
3. Vary the RF level in 10dB steps and check that the RSSI output voltage changes at a rate of a
10dB/V (±0.20VDC) over the range of –120dBm to –80dBm. If the requirement cannot be
reached, contact your Dataradio technical support.
120 20170-200 ParagonPD Technical Manual35

switch)
3. Transmit a square wave by pressing the BDLCPD’s PF1 button and following the procedure out-
lined in section 3.2.1.1.2.2 or run on another computer the RIS program and press the Flatness test
button. Adjust RV-105 (REF MOD) close to the microphone connector, for best wave shape; no
damping, no overshoot. Record the deviation read.
4. If transmission has not ended by itself, press PF1 or RIS’ Flatness test button again to stop it. For
single-channel unit, proceed to step 7.
5. For multi-channel unit, select the highest frequency channel. Transmit a square wave by pressing
the BDLCPD’s PF1 button and following the procedure outlined in section 3.2.1.1.2.2 or run on
another computer the RIS program and press the Flatness test button. Record deviation again.
6. The difference in deviation between the two channels should be less than ±300 Hz. If not, re-
adjust RV105 to "average" the square wave shape on both channels until the spec is met.
7. To confirm the adjustment, select the active, or the lowest frequency channel. Compare the devia-
tion produced between:
- TX ON (Modulated) and
- Random data tests,
The difference should be lower than 300 Hz. For multi-channel unit, repeat this step on the highest
frequency channel.
8. Select the active channel. Transmit a TX ON (Modulated) adjustment tone by pressing the
BDLCPD’s PF1 button and following the procedure outlined in section 3.2.1.1.2.2 or run on an-
other computer the RIS program and press the TX ON (Modulated) button. Make sure that devia-
tion level read on the IFR correspond to model and bit rate in use (see Table 8 - Typical Carrier
Modulation). Re-adjust deviation as necessary referring to Checklist B - page 26.

2. Key the Exciter by pressing the module PTT button. The output power must be:
- 800 MHz (T881) = 5W ±300mW.
3. If 5Watts is not reached, adjust helical #L300 for maximum power output (which should be at
least 7W); adjust RV356 down to 5W.
120 20170-200 ParagonPD Technical Manual37
6.2.4 Power Amplifier Module (T889)
1. Re-install the exciter module into the Paragon rack frame
2. Connect the Exciter module to the Power Amplifier
3. Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD style power
meter, terminated with a 150W dummy load.
6.2.4.1 Power Amplifier Power Out
1. Set RV63 (Power adjustment, access on the front panel) fully clockwise.
2. Key the transmitter from the exciter Carrier button. The power output should exceed 90W.
3. Adjust RV69 (Driver power, access from the left end side) until the output power drops to 90W.
4. Adjust RV63 (Power) to reduce power output to its nominal value (70W) or lower as required.
5. Cable loss should be included in the reading.
6.2.4.2 Forward Power Alarm Level
1. Power up the T889 and adjust RV63 (Power) so that the output power is at the alarm level re-
quired, usually 20% lower than nominal value (e.g. 40W if the PA normally operates at 50W).
2. Adjust RV48 (Forward power Alarm set) so that the forward power alarm LED lights.
3. Adjust RV63 (Power) for the normal operating power level.
6.2.4.3 Reverse Power Alarm Level (Optional)
1. Power up the T889 and adjust RV63 (Power) for the normal operating power level.
2. Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust RV52 (reverse power
alarm set) so that the reverse power alarm LED lights.
Example: A VSWR of 3:1 can be simulated by connecting an undetermined 3 dB pad to the PA output.
This will result in a loss of 6 dB.

by an underlined letter on the menu command.
- On a drop-down menu, press only the hotkey without pressing the “Alt” key.
- Use the “Tab” key to cycle available fields and the “Enter” key to validate entries. E.g.
Pressing “Alt”+F opens the File drop-down menu and pressing “A” opens the Save As di-
rectory service box.
Receiver VCO and front-end alignment will be required when new receiver frequency is pro-
grammed outside the radio tuning range:
UHF = ± 2.5 MHz from previous center frequency.
VHF = ± 1.5 MHz from previous center frequency.
Exciter and PA alignment will be required when new transmitter frequency is programmed outside
the radio tuning range:
VHF & UHF= ± 4 MHz from previous center frequency.
1. Connect the PC, via the supplied programming lead, to the speaker panel’s front-mounted
RJ11 connector.
2. Run Tait PGM800Win program and follow instructions found in the T800 Programming Soft-
ware User’s Manual to select the proper module to be programmed.
3. Program required channel's frequencies.
– Do not program any CTCSS tones on channels.
– Do not change any other parameters.
– Refer to Figure 23, Figure 24, Figure 25 and Figure 26 for screen program examples.

6.3.3 Channel Selection via DIP Switches
The backplane-mounted DIP switch settings override the default channel programmed by
PGM800Win.
To set a default channel via the software, all DIP switches must be set to “OFF” (i.e. 00000000).
When a switch is “Off”, its binary count is active; when a switch is “ON” its binary count is inac-
tive.
The various DIP switch combinations of ON or OFF make up a binary total, which identifies the
channel number. To select a channel, set the appropriate DIP switch or switches to “OFF” to make
the binary count total the channel number you want. Set all other switches to “ON”.
It is recommended to set both SW1 (RX) and SW2 (TX) to the same settings.
Example: To select channel 5, set the DIP switches as shown in below:

6.4.2.4 SINAD and Linearity Check
1. Apply the following settings to the IFR:
a) Generator mode, Output T/R
b) IFR TX frequency to match the main radio RX frequency
c) Filter set to wide band (no audio filter)
120 20170-200 ParagonPD Technical Manual47
d) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off.
e) Set deviation to ±3.0KHz for full channel or ±1.5KHz for half channel radios.
f) Use a X1 scope probe connected to IFR SINAD input and monitor the Discriminator O/P
on the backplane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at
the receiver TP314 (T855) or at the receiver IC350 pin 7 (T835)
2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm (in-
cluding cable loss).
3. Offset the IFR TX frequency 2kHz (full channel) or 1kHz (half channel) above the main radio
RX frequency, record the SINAD reading. It should remain within 1dB from the on frequency
SINAD reading. For T855, use above values, for T835 use 1.5kHz (full channel) or 0.8kHz
(half channel).
4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main radio
RX frequency, record the SINAD reading. It should remain within 1dB from the on-frequency
SINAD reading. For T855, use above values, for T835 use 1.5kHz (full channel) or 0.8kHz
(half channel).
Note: If one of the above requirements is not met, try to re-tune the front-end. It
still failed, contact your Dataradio technical support.
6.4.2.5 RSSI Adjustment (UHF: T855)
Note: This check is only recommended for Paragon/R model running DBA protocol 3.06.009
series or later.
- Apply an on-channel signal from the RF generator at a level of -110dBm with deviation of
±3kHz (full channel) or ±1.5kHz (half channel) at 1kHz tone.
- Adjust RV320 (RSSI level) to give 2.0V RSSI output at SK330 pin 2 or on backplane SK1 pin
5 when measured with a voltmeter (See Figure 30).
- Vary the RF level in 10dB steps and check that the RSSI output voltage (SK1 pin5) changes at
a rate of a 10dB/V (±0.20VDC) over the range of –120 dBm to -80dBm (see Figure 28). If the
requirement cannot be reached, contact your Dataradio technical support.

6.4.2.6 RSSI Adjustment (VHF: T835)
Note: This check is only recommended for Paragon/R model running DBA protocol 3.06.009
series or later.
- Apply an on-channel signal from the RF generator at a level of -100dBm with deviation of
±3kHz (full channel) or ±1.5kHz (half channel) at 1kHz tone.
- Adjust RV320 (RSSI level) to give 4.5V RSSI output at RSSI test point (near of quad. Coil
L360) or on backplane SK1 pin 5 when measured with a voltmeter
- Vary the RF level in 15dB steps and check that the RSSI output voltage (SK1 pin5) changes at
a rate of a 15dB/V (+/- 0.30VDC) over the range of -120 dBm to -80dBm (see Figure 29). If
the requirement cannot be reached, contact your Dataradio technical support.

6.4.3 Exciter Module (T857 or T837)
Note 1: Refer to Figure 33 (T857) and to Figure 35 (T837) for locating tuning controls and com-
ponents.
Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will flash
indicating that it needs re-tuning.
Warning: The LED will also flash when the unit is in setup mode while connected to the
PGM800win program.
6.4.3.1 Initial Setup
1. Shut down power to the base station
2. Prepare the multimeter to DC Volts.
3. Remove the exciter (T857 or T837) module from the base station rack frame
4. Remove the exciter top cover (nearest the handle).
5. Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R out-
put and the exciter antenna connector.
6. Connect the ParagonPD Extender Rail Kit to the empty chassis exciter slot.
7. Apply power to the base station
6.4.3.2 Synthesizer Alignment
Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the syn-
thesizer loop voltage).
1. T857 (UHF) Tune VCO trimmer C6 for a synthesizer loop voltage of 10V DC.
2. T837 (VHF). Tune VCO trimmer CV1 for a synthesizer loop voltage of 9VDC.
Multiple channels:
1. T857 (UHF) Adjust the VCO loop to 10V using the middle channel.
2. T837 (VHF) Adjust the VCO loop to 9V using the middle frequency channel.
All channels should lie within the upper and lower limits of 16V and 3V respectively for
the T857 and within 13V and 5V for the T837.
Note:
Normally, the fast TX key option is installed and the synthesizer is always ener-
gized. In the case where that option was not fitted, we must key the transmitter by
pressing the front panel Carrier button to make the above adjustment possible.
6.4.3.3 TX Frequency Error Adjustment
1. Apply the following settings to the IFR:
- Receiver mode
- IFR RX frequency to match the main radio TX frequency
- IF Filter set to 30KHz
- Zoom the RF Error window: select 10Khz range
120 20170-200 ParagonPD Technical Manual50
2. Key the transmitter by pressing the front panel TX-Key button and measure the carrier
output frequency. It should be within ±300 Hz. If it is not, adjust the TCXO to trim to
meet the requirement, preferably within 100Hz.
6.4.3.4 Low-Frequency Balance Adjustment
PGM800Win controls this adjustment. Electronic potentiometer (256 step) is used to allow chan-
nel adjustment of two-point modulation (Low freq. balance).
1. Apply the following settings to the IFR:
– Receiver mode and Oscilloscope display (Source Demod out connector, DC cou-
pled).
– IFR RX frequency to match the radio transmit frequency
– IF Filter set to 30KHz
– Zoom the Deviation window: select 10kHz Range and DC coupling.
2. Select the active or, the lowest (in the case of multi-channel base) frequency channel (via
dip switch)
3. Transmit a square wave by pressing the BDLCPD’s PF1 button and following the proce-
dure outlined in section 3.2.1.1.2.2 or run on another computer the RIS program and press
the Flatness test button. You can also run both programs on the same computer if two se-
rial COM ports are available.
4. Adjust IC220 via PGM800Win “reference modulation” to obtain the best square wave, no
damping, no overshoot. (You can use either the mouse or up and down arrow keys). Rec-
ord the deviation read.
5. If transmission has not ended by itself, press BDLCPD PF1 or press RIS’ Flatness test
button to stop it. For single-channel unit, proceed to step 7.
6. For multi-channel unit, select the highest frequency channel. Transmit a square wave by
pressing the BDLCPD’s PF1 button and following the procedure outlined in section
3.2.1.1.2.2 or run on another computer the RIS program and press the Flatness test button.
Record deviation again.
7. The difference in deviation between the two channels should be less than ±300Hz. If not,
re-adjust IC220 to "average" the square wave shape on both channels until the spec is
met.
8. To confirm the adjustment, select the active, or the lowest frequency channel. Compare
the deviation produced between:
- TX ON (Modulated) and
- Random data tests,
The difference should be lower than 300 Hz. For multi-channel unit, repeat this step on
the highest frequency channel.
8. Select the active channel. Transmit a TX ON (Modulated) adjustment tone by pressing
the BDLCPD’s PF1 button and following the procedure outlined in section 3.2.1.1.2.2 or
run on another computer the RIS program and press the TX ON (Modulated) button.
Make sure that deviation level read on the IFR correspond to model and bit rate in use
(see Table 8 - Typical Carrier Modulation). Re-adjust deviation as necessary referring to
the related Checklist (B for ParagonPD - page 26
120 20170-200 ParagonPD Technical Manual51
6.4.3.5 Exciter Power Output
1. Apply the following settings to the IFR:
- Receiver mode, Output T/R
- IFR RX frequency to match the main radio TX frequency
- IF Filter set to 30KHz
- Select auto range in the Power reading window
- Connect the coaxial cable from the IFR T/R to the Exciter output connector
2. Key the Exciter by pressing the module PTT button. The output power must be:
- VHF (T837) = 800 mW ±200mW
- UHF (T857) = 1W ±300mW
6.4.4 Power Amplifier Module (T859 or T839)
- Re-install the exciter module into the ParagonPD rack frame
- Connect the Exciter module to the Power Amplifier.
- Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD
style power meter, terminated with a 150W dummy load.
- Forward and reverse power alarm set (control) are identified on the PA cover.
6.4.4.1 Power Amplifier Power Output
- Key the transmitter on the exciter and adjust the PA output for 100W using front panel
power control. If power cannot be reached, refer to section 6.4.4.4 for T859 UHF model
or to Tait T839 service manual for T839 model. Cable loss should be included in the
reading.
6.4.4.2 Forward Power Alarm Level
1. Power up the PA and adjust front panel power control so that the output power is at the
alarm level required, usually 20% lower than nominal value (e.g. 40W if the PA normally
operates at 50W).
2. Adjust the forward power alarm set (T859: RV48 or T839: RV101) so that the forward
power alarm LED lights.
3. Adjust front panel power control (T859: RV63 or T839: RV109) for the normal operating
power level
6.4.4.3 Reverse Power Alarm Level (Optional)
1. Power up the PA and adjust the front panel power control for the normal operating power
level.
2. Place a known mismatch of the required value (e.g. 3:1 VSWR) and adjust the reverse
power alarm set (T859: RV52 or T839: RV105) so that the reverse power alarm LED
lights.
Example:
A VSWR of 3:1 can be simulated by connecting an unterminated 3dB pad to the
PA output. This will result in a return loss of 6dB.
120 20170-200 ParagonPD Technical Manual52
6.4.4.4 Tait T859 (UHF) Standard Tuning Procedure
1. For sets with serial numbers following 217262, set RV69 (driver power level) fully
clockwise.
2. For all units, preset the tuning controls as shown in Figure 31
Figure 31 - T859 Tuning Settings
3. Set RV63 (front panel power control) fully clockwise.
4. Key on the exciter (press PTT button).
5. Adjust CV1 for maximum output.
6. Adjust CV8 for maximum output.
7. Adjust CV32 for maximum output.
8. Adjust CV51 and CV57 for maximum output.
9. Adjust CV34 and CV35 for maximum output.
10. Recheck all settings. The power output should exceed 110W.
11. For sets with serial numbers following 217262, adjust RV69 (driver power level)
until the output power drops to 110W.
12. For all units, adjust RV63 to reduce the power output to the required level (normally
100W).
6.4.4.5 Tait T859 Tuning for Best Efficiency
1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red
wire and its 13.8Vdc output, then connect the shunt to the multimeter (VDC scale)
2. While transmitting, monitor the current. It should remain under 22A.
3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply
current, but do not exceed a maximum drop of 0.5A per control.
4. Check that the supply current is <22A for 100W output power.
Note:
These control settings are normally very close to minimum supply current. If the cur-
rent is reduced too far, maximum power output will drop and 2f rejection may degrade.

Appendix 1 - ParagonPD Deviation adjust
1. Using the RIS, press TX ON (Modulated) and record deviation level as read on the IFR.
2. Using Windows Notepad, Edit the .bp2 file named with the corresponding BDLCPD serial
number (e.g. abcd.bp1). “Save as” to another file name and keep it in case something goes
wrong while changing a parameter.
3. Locate the line labeled “Dev0 Par85=” and record the value beside the “=” sign. This is the
corresponding parameter value to the deviation read in step 1.
4. Apply the following formula to determine the new parameter value to be set:
(New Par85 value) = [(initial Par85 value) X (target deviation) / (deviation read)] + 2
5. Change the value in the file, “Save as” using the BDLCPD serial number file name.
6. Run the RIS again and do a “Put From”. From the opened window, select the file that you just
made the change to and then press “OK”
7. Again, check deviation level while pressing TX ON (Modulated). If fine-tuning of Par90 value
is still required, Edit the file again and re-do step 5 by changing directly the Par85 value by 1
or 2 up or down.
8. Re-check deviation level. If the level is now correct, press Stationreset to make the change
permanent.
