1.6 Radio Series I or II
System-engineered installations use one of two
complements of ParagonPD radio modules. To
identify the radio series model, check the part
number on the manufacturer’s label at the back
of the Receiver and Exciter:
- T8nn-nn identifies a Series I model.
- T8nn-nn-nnnn identifies a Series II model.
where “n” denotes a number.
Examples:
- T881-10 is a Series I Exciter (850–870 MHz)
- T881-10-0000 is a Series II Exciter (850–870
MHz)
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Series I models are no longer available, superseded
by Series II.
Series II models:
- VHF, UHF and 800MHz frequency range
radios.
- 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 to
power ParagonPD (<6A) and ancillary equip-
ment.

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 at 13.8VDC. It supplies all the radio
modules other than the Power Amplifier.
• A T808 using convection and fan cooling is
rated up to 25A at 13.8VDC. 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
grounding 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
distribution to the Radio assembly.
The power supply front panel LEDs indications
are:

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 Windows Radio Installation
Software (WinRIS) program for testing or trou-
ble-shooting.
Any change(s) to the settings must be done via
files saved on diskette and loaded into the unit
using the WinRIS program.

3.1.1.5 Dual Power Supply module
The Dual Power Supply module is made up of
two separate power supply units coupled in a
single chassis.
Refer to Table 1 on page 7 for tabular listing of
power supply LEDs indicators.
Refer to Figure 1 for the front panel LED lay-
out.
This module has:
• Two “Power” red-colored pushbutton
switches - Push in for ON and release out
for OFF. Control complete power distribu-
tion to the Radio assembly
• Two “ON” LEDs - light green when push
button(s) is (are) ON; DC power is distrib-
uted to radio modules. Flash green in con-
junction with the “OL” LED (flashing red)
when an over voltage condition 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 over-
load, light steady red when supply exceeds
current limit set; nominally 25Amps (T808
model). Flashes red in conjunction with the
ON LED (flashing green) when an over
voltage condition is present.

to both backplanes). Used for programming
the Radio Assembly whenever the speaker
panel has been removed.
This feature is exclusive to the Series II
model. Series I model’s programming is
done externally via EPROMs.
• DB-25M plug at PL1 (one side of the “Y”
cable on each PCB) – used to supply the re-
ceive signal to the BDLCPD’s single
“EXT.RADIO/TEST” DB-25F plug.
• Two channel-select DIP switches (SW1 and
SW2)
This feature is exclusive to the Series II
model.
• Cooling fan driver – CN2 located on back-
plane connects to the horizontally-mounted
fan on top of the Radio assembly and acti-
vated by BDLC’s PTT signal.
• Coaxial relay driver – not used.
3.2 BDLCPD
The rack-mounted BDLCPD is housed in a steel
case. It has no user serviceable parts. Unit’s
configuration 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 val-
ues 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 20170-204a ParagonPD Technical Manual
13
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.

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).

Notes:
- For DGFSK models, a dotting pattern consists of an
alternating series of bits.
For the SRRC4FSK models, only the lowest-level
symbol’s modulation is used.
- The square wave is used to check transmitter low
frequency balance.
- The 1000 Hz sine can be used for transmitter distor-
tion measurements.
- Pattern 6 produces a transmission of approximately
55 seconds followed by about 55 seconds of silence.
Initial transmission in a sequence may be shorter than
55 seconds. TX LED stays steadily red for duration of
the test. 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 un-
til 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
function 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
being 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 trans-
mitted.
• 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.

Figure 13 - RS-232 Port LED indicators
CM Command Mode - LED lights and re-
mains lit while the selected port is ac-
cessing the Command Processor. It
lights ON and OFF while being config-
ured.
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 re-
ceive 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 being held off.
RD Receive Data - when lit, it shows that
the Receive Data pin 3 on the RS-232
interface 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 in-
terface. 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.

LF Link Failure - when lit, indi-
cates that the base station fails to re-
ceive an ACK for a packet sent and for
all subsequent retries. 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 WinRIS program (DMP/Setup
19200). Can also be used with special
user’s application such as telephone
modem. Note: connection to a tele-
phone requires the use of a DCE Cross-
over cable.
– 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
b) MSCP 19200 for multi-site installa-
tions
• One DA-15M connector:
- DEV6 Digital I/O - not used
• One DB-25M connector:
- EXT RADIO/TEST - connects to the
Radio assembly (see Figure 15)

Figure 15 - BDLCPD Y cable and pinout
Important note:
The aggregate total baud rate for all active ports on a BDLCPD must not exceed 30,000 for Para-
gonPD. Sustained simultaneous operation on devices 1 and 3, using the factory settings for these
ports, may result in lost characters.
Using the factory settings, device 3 is intended only for use during configuration and should not be
used simultaneously with data traffic on device 1. For special user application done while the
BDLCPD is active, use either device 2, or set device 3 to 2400 bauds.

4. WinRIS program1
The Windows Radio Installation Software
(WinRIS) 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).
To run the program, you will need:
- A PC or portable computer running a 32-bit
MS-Windows application:
(Each program copyright © Microsoft Corpora-
tion. All rights reserved.)
Win ME
Win2000
Win NT
Win 9x
(For Win 95, if COMCTL32.DLL has been
updated to the most recent version and
copied to the \windows\system\ directory).
Note:
WinRIS does not operate under:
- Win CE (embedded in PocketPC)
- 16-bit Windows 3.x
- A hard disk.
- An available COM port.
A serial mouse, with its own driver installed is
strongly recommend however most actions can
also be done using keyboard command
4.1 Operation
This support program can be run in MS-
Windows mode.
DO NOT have more than one copy of this pro-
gram loaded at any given time in separate win-
dows. Doing so creates COM port sharing con-
flicts and failure to run the program alone re-
sults in unexpected transmissions.
1 For descriptions of features revised or added to
WinRIS versions later than 3.xx, please refer to the
program’s context-sensitive help or type FI
Only left mouse button operation is supported.
Any command or selection shown in gray is ei-
ther unavailable or is awaiting another action
before activating.
Help in the program is available at all points by
pressing the F1 key. If a subject is highlighted,
the help displayed will be context sensitive.
4.2 To connect and start
WinRIS
All families of MobilPacs, Paragons, Gem-
iniPD’s and ParagonPD’s share a common Win-
RIS program available on diskette, Dataradio
p/n 980 03392-00n.
Refer to the WinRIS Readme.txt
file for details on how to set the
MS-Windows environment, and
how to connect, install and run
this program.
In summary, before starting the WinRIS when
running MS-Windows, click on “Start”, then on
"Run". Type the relevant path and variables on
the command line (or select by browsing) lead-
ing to:
WinRIS.EXE COM[x], [speed],8,n,1
(where x is the PC COM port to be used) Of
course, the executable command may be used
alone without any variable added.
Click on “OK”.
It is also possible to create a PC desktop short-
cut icon for WinRIS:
In MS-Windows 98
• Start by right clicking anywhere on the
desktop,
• Select New,
• Select Shortcut and type the path as detailed
above directly on the command line (with or
without variables).
• Click Next,
• Type in an applicable name for the shortcut
icon,
• Click Next
• Select an icon (your choice) and
• Click on Finish.

Command line settings override the environment
variable, if any.
4.3 WinRIS Window
Refer to your version of WinRIS for its main
screen appearance. WinRIS detects the product
it is used with and the screen’s design adjusts to
the product’s particular structure. Future ver-
sions will also introduce new features. The pro-
gram’s context-sensitive help (or accessible via
the FI function key) is the best source of infor-
mation on items not covered in this section.
Generally, this program uses only one main dis-
play screen. Placing the cursor over a Toolbar or
Button generates a ScreenTip. Starting at the
top, the screen display is made up of:
• A Menu bar, containing the menu names
listed below. They give access to command
options. Unavailable commands are shown
in light gray color. Shortcut keys are listed
whenever available.

abled for ParagonPD.
4.4 Port Configuration
Window
At program’s launch, WinRIS opens the “Port
Configuration window”.
Enter the COM port and speed that should be
used. The program defaults to 8 bits, no parity
and one stop bit. Make necessary modifica-
tion(s) to entries if needed and click on Save to
go to main screen (a delay of several seconds
may occur). If COM port and speed are already
saved, the program automatically goes to the
main screen.
1. In the COM Port list box, select the COM
port (1,2,3 or 4) to use for connection.
Note: the COM Ports selections numbered 5
to 32 are used (at factory) to upgrade sev-
eral units from the same computer USB
port.
2. In the Baud rate list box, select the baud rate
to use that matches your unit. The available
choices are 4800, 9600, 14400, 19200 or
38400.
3. Bits options are 7 or 8 (default)
4. Parity options are N (default), odd or even
5. Stop bits options are 0, 1 (default) or 2
Make the relevant entry in the “Connection
Type --- Base Only” box as follows:
1. In the first drop-down list-box, select either
“Direct connected” or “Connected via an
MSC”.
• If the selection was Direct connected,
The second drop-down list box is avail-
able, select either “Using DMP” or
“Using MSCP”.
The Logical Tower ID single-line entry
box is not available.
• If the selection was Connected via a
MSC,
The second drop-down list box is not
available.
The Logical Tower ID single-line entry
box is available. Enter the relevant
Logical ID.
The Logical ID is a unique number as-
signed to the MSC-tower-base link when
the MSC is configured. Logical ID
numbers for MSC-tower-base links are
usually assigned numbers 1 to 100,
leaving numbers 101-126 for use with
Hosts.
2. Click the Save button to validate your
choice(s) and start the connecting process.
To exit the window without making any change,
click on Cancel.
Notes:
Enable the “Always ask port configuration
when WinRIS start” box to have the Port Con-
figuration window always opening at start up.
Two instances of WinRIS may be run. One ap-
plication runs on one COM port and the second
on another port. This feature allows testing a
mobile and a base station on one computer that
has two COM ports.
Ensure that mobile unit is in DMP mode.
4.5 Functions
The WinRIS program is used to:
• Save an existing configuration from a unit to
a file.
• Take a configuration from a file and upload
it to a unit
• Check ParagonPD’s transmit functions
• Test and/or trouble-shoot installations
4.5.1 “Station Reset” button
On the menu bar, select “Test”, then the “Sta-
tionreset” command or press the “Stationreset”
button on the Toolbar to issue a stationreset
command to the modem.
The Stationreset button is pressed as a last step
after doing a “Put From”. It causes downloaded
parameters from a file or diskette to take effect
in the connected unit.
Pressing Stationreset is not required after doing
any Comments or Password configuration
120 20170-204a ParagonPD Technical Manual
21
change as these have their own Put Comments
and Put Password buttons.
StationReset does not break the connection.
4.5.2 Configuration to a file
Saving the unit’s configuration to a file allows
the user to:
• Subsequently restore the configuration.
• Safeguard a copy as documentation of the
configuration.
Note: The configuration and status files are
ASCII files and may be e-mailed or faxed to
technical support when requested to do so.
Warning:
Do not make any changes to these files. Any
changes made to the configurations MUST be
done at factory or by Dataradio system engi-
neering.

On the menu bar, select “File”, then the “Get”
command or press the “Get” button on the
Toolbar to:
• Establish linking
• Download and automatically save the con-
nected unit’s configuration setting to a file
named with the unit' serial number: The
WinRIS status bar will then report “All pa-
rameters are successfully retrieved and
saved in file [unit' s/n].BP2. Any previous
configuration in the program is overwritten.
If you do not wish to overwrite an existing con-
figuration or prefer to name the file yourself,
use the “Get As” button.
4.5.2.2 “Get As” button
After communication is established using the
Connect button, press the Get As button to:
• Open the “File, Save As” window with the
ASCII file *.bp2 (already selected). Save the
connected BDLCPD’s operating characteris-
tics (configuration setting) to a file, direc-
tory or drive of your choice.
The program will ask before overwriting an
existing file.
• Status bar reports “All parameters are suc-
cessfully retrieved and saved in [file-
name]”.
4.5.3 Configuration from a File
Loading a configuration from a file to a unit is
useful to:
• Restore the operating characteristics of a
unit (Requires intervention with technical
support.)
• Carry out field updates using Dataradio
system engineering supplied diskette(s).
Warning:
Do not make any changes to these files. Any
changes made to the configurations MUST be
done at factory or by Dataradio system engi-
neering.
4.5.3.1 “Put From” button
1- On the menu bar, select “File”, then the “Put
From” command or press the “Put From”
button on the Toolbar.
2- In the “Open” window, locate the drive, di-
rectory and file name of the relevant file.
• This may be a configuration saved ear-
lier from a unit.
• It can also be from a Dataradio (factory
or system engineering) diskette.
4- Select the appropriate file
5- Press the “OK” button.
The status bar reports: “[filename] is
downloading into unit” and up to 30
seconds later displays: “All parameters are
saved. Apply Station Reset to take effect!”
6- Press the “Station Reset” button. See section
4.5.1 for details.
4.5.4 Special Functions
The following WinRIS fields and buttons are
used to gather specific information concerning
the connected unit:
120 20170-204a ParagonPD Technical Manual
22
• Banner field
• Comments field and Put Comments button
• Password and Put Password button
4.5.4.1 Banner Field
On the menu bar, select “View”, then the
“Product ID” command to retrieve the “Banner”.
Useful for product and firmware identification,
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 is:
[serial number]:firmware 1 name, its version #,
firmware 2 name, its version #.
The serial number portion uniquely identifies
the unit. It is a variable length, maximum eight-
character alphabetic string assigned at the time
of manufacture. It is identical to the serial num-
ber printed on the label of the unit. This number
cannot be changed and is used as part of the on-
air protocol.
ParagonPD's firmwares reside in flash EPROM
and are designed to allow field upgrades.
When contacting your supplier, give the full
banner string and the version of the WinRIS
used. You will find the version number by se-
lecting the “Help” menu option, then “About
WinRIS” command or pressing the “About”
button on the Toolbar.
The “Banner” field is blank prior to doing a
"Get", "Get As" or "Put From".
4.5.4.2 Comments
1- Type comments directly in the “Comments”
field. These can be text up to 24 characters.
Use this field to enter user-convenient de-
scription(s) (customer name, location,
etc…).
2- Press the button “Put Comments” to make
the entry permanent. This field may be left
blank.
On subsequent “Get”, “Get As” or “Put From”,
this field displays entered comments. If no
comment was entered, the field will remain
blank.
4.5.4.3 Password
The password feature is useful where two (or
more) fleets share the same radio channel. Mo-
biles without the proper password would still
receive the message but the contents would not
be intelligible.
1- Type your password directly in the “Pass-
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 “Get”, “Get As” or “Put From”,
this field displays entered comments. If no
comment 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,
Dataradio urges you to use external encryption
technology such as Data Encryption Standard
(DES) in the Host and Mobiles computers.
4.5.5 Test Functions
The following WinRIS functions and buttons
are used to carry out testing or trouble-shooting
on a connected unit:
• DSR signal is High indicator
• CTS signal is High indicator
• TXON (Modulated)
• TXON (Unmodulated)
• Square Wave
• Random Data
• Addressing and Device fields
120 20170-204a ParagonPD Technical Manual
23
4.5.5.1 DSR signal is High indicator
The “Data Set Ready” (DSR) indicator light,
located on the button bar (leftmost), is an RS-
232 protocol port indication. When lit, it indi-
cates proper connection and that the value is
High. The DMP protocol used requires that
DSR be normally asserted.
4.5.5.2 CTS signal is High indicator
The “Clear-to-Send” (CTS) indicator light, lo-
cated on the button bar (second indicator from
the left), is an RS-232 protocol port indication.
When lit, it indicates proper connection and that
the value is High. The DMP protocol used re-
quires that CTS be normally asserted.
4.5.5.3 Channel Selection
ParagonPD uses its default radio channel. No
channel selection being available, all channels
are grayed-out and the “Show All Channel Fre-
quencies” button is disabled.
4.5.5.4 TXON Tests
TXON test functions are selected by choosing
“Test” from the file menu, then “Modulated”,
“Unmodulated”, “Random” or “Square Wave”
command or by pressing the relevant button on
the Toolbar. All other commands and buttons
are inactive during test transmissions.
4.5.5.4.1 Unmodulated Carrier
Unmodulated carrier gives a clear carrier and is
frequently used for checking:
• Frequency error
• Forward and reverse power
Press the TXON (Unmodulated) button to
transmit an unmodulated 20-seconds test signal
on the channel selected or until the button is
pressed again.
Power check:
1- Connect an in-line power meter between the
radio and the antenna.
Measure the forward and the reflected power
levels by powering TX ON. Reflected power
should be <5% of forward power (or as speci-
fied by System Eng.). See Table 9 for further
details.
4.5.5.4.2 Modulated Carrier
Test transmission generates a carrier modulated
with 1kHz sinewave, at deviation level that de-
pends on model and network speed as shown in
Table 8.
This function is frequently used for checking
frequency deviation.
Press the TXON (Modulated) button to begin
transmitting a 20-seconds modulated test signal
on the channel or until the button is pressed
again.
4.5.5.5 Random Data
Generates a 20-seconds random data signal.
Pressing the ‘’Stop’’’ button halts the ongoing
test.
This test function is used for checking low-
frequency balance and maximum deviation over
data.
• Low-frequency balance check:
Helps to determine if the radio transmitter is
well balanced for data transmission.
Refer to Table 10 - Checklist B (General)
for values indicated in adjustment tables
under “Low Frequency Balance” step.
• Maximum deviation check:
Helps to verify if the unit is within FCC
regulation emission masks.
Refer to Table 8 - Carrier deviations for Tone or
Data Modulation for maximum data deviation

5. Testing and Trouble-
Shooting
The checks described below should be done at
time of installation, annual intervals or when-
ever 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
service 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 prob-
lems 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.

6. Radio Programming and Adjustments
All receiver procedures detailed in this section should be done twice: once for the “Main” (or RX1) re-
ceiver module and a second time for the “Auxiliary” (or RX2) 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 ParagonPD 800 MHz versions. Series I is now superseded by Series II. This proce-
dure applies to Series I only and is a supplement to the Tait programming 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)
- EPROM Programmer software BP MicroSystems’s (Version 3.08 or later)
- 27C64 EPROM (150 nanoseconds or faster)
- 486 PC or better, Ms-Windows 3.1 © or later
- Standard 25-pin parallel cable (terminated Male/Female)
6.1.2 Introduction
Before starting programming, have a PC running MS-Windows and the Tait PGM800Win software for
Series I Base station. It will be needed to generate a binary file required in programming the EPROM.
This program supports the use of a mouse but may be used without one if required. Keyboard access
follows the conventional MS-Windows © method as briefly described below:
- Press and hold the “Alt” key while pressing the relevant hotkey (indicated by an underlined letter on
the menu command).
- On a drop-down menu, press only the hotkey letter 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 directory service box.
For full description of the programming procedure, refer to the T800 Programming Software User’s
Manual.
• Receiver VCO and front-end alignment will be required when new receiver frequency is programmed
outside the radio tuning range: ± 3 MHz from previous center frequency.
• Exciter alignment will be required when new transmitter frequency is programmed outside the radio
tuning range: ± 4 MHz from previous center frequency.

Note 1: Refer to Figure 19, page 40 for locating tuning controls
Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will be flashing
showing that it needs to be re-tuned.
6.2.2.1 Initial Setup
This initial setup will be used during each receiver alignment procedures that follow:
1. Remove the receiver (T885) module from the ParagonPD rack frame
2. Remove the receiver top cover (nearest the handle).
3. Connect the ParagonPD Extender Rail kit between the RX module and the empty chassis re-
ceiver slot.
4. Set the multimeter to read DC Volts.
5. Apply power to the ParagonPD.
6.2.2.2 Synthesizer Alignment
Single channel: Connect the multimeter to the long lead of L1 in the VCO (this measures the
synthesizer loop voltage). Tune VCO trimmer C6 for a synthesizer loop voltage of 7V (working
range is between 3V to 10V).
Multiple channels: Select the middle channel via the EPROM PCB DIP switch.
Adjust the VCO loop to 7V.
All channels should lie within the upper and lower limits of 10V and 3V respectively.
6.2.2.3 Front-End Alignment
1) IFR COM120B settings:
a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output
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 28 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.
(minimum 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 20170-204a ParagonPD Technical Manual

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).

6.3 Series II Radio Programming
This procedure describes the steps needed to program the UHF, VHF & 800MHz model that use the
ParagonPD base station radios (half & full channels).
6.3.1 Recommended Items
- 486 PC or better, MS-Windows 3.1 © or later
- T800win programming kit for Series II:
- PGM800Win programming software user's manual
- PGM800Win Windows based programming software
- T800-01-0002 programming cable (DB-25 to RJ-45 cable)
- Standard 25-pin parallel cable (terminated Male/Female)
6.3.2 Module Programming
Before starting programming, have a PC running MS-Windows © and the Tait PGM800Win software for
Series II Base station.
This program supports the use of a mouse but may be used without one if required. Keyboard access
follows the conventional MS-Windows © method as briefly described below:
- Press and hold the “Alt” key while pressing at the same time the relevant hotkey as indicated 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 directory service box.
Receiver VCO and front-end alignment will be required when new receiver frequency is programmed
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 con-
nector.
2. Run Tait PGM800Win program and follow instructions found in the T800 Programming Software
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 21, Figure 22, Figure 23 and Figure 24 for screen program examples.
4. Save the base station programming info to a file for further reference.

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 inactive.
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 on both back plane boards.
Example: To select channel 5, set the DIP switches as shown below:

All channels should lie within the upper and lower limits of 16V and 3V respectively for the T885
and T855 or within 13V and 5V for the T835.
6.4.2.3 Front-End Alignment
1. IFR COM120B settings:
a) Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output
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 1KHz sine
e) Select SINAD meter
f) Use a X1 scope probe connected to 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
I/O Pad P207 (T885), the receiver TP314 (T855) or at the receiver IC350 pin 7 (T835).
2. Adjust the helical resonators for best SINAD: #H400, #H401 and #H900 (T885); #FL410 and
#FL420 (T855) or L410, L420, L460 and L470 (T835).
3. Continually decrease the RF level to reach 12dB SINAD, then re-do step 2) & 3) again. (mini-
mum requirement to reach is 12dB SINAD for -110dBm)
4. Perform the SINAD linearity tests described in paragraph 6.4.2.4. If it fails to pass the require-
ment, contact your Dataradio technical support.
WARNING: Do NOT attempt to re-tune the IF stages
(I.e. L300 and L301 for T885, L310 to L390 for T855 or L330 to L360 and
CV318 for T835).
These adjustments do not need to be re-adjusted after frequency re-programming.
Touching these coils will have a direct impact on the modem DSP coefficient set-
tings and may reduce significantly the radio performances over data.
6.4.2.4 SINAD and Linearity Check
1. Apply the following settings to the IFR:
a) Generator mode, Output T/R
120 20170-204a ParagonPD Technical Manual

c) Filter set to wide band (no audio filter)
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
I/O Pad P207 (T885), 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 (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 1dB from the on frequency
SINAD reading. For T885 and 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 T885 and 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. If still
failed, contact your Dataradio technical support.
6.4.2.5 RSSI Adjustment (T885 and T855)
- Apply an on-channel signal from the RF generator at a level of -110dBm modulated by a one kHz
tone at a deviation of ±3kHz (full channel) or ±1.5kHz (half channel).

frequency. It should be within ±300 Hz. If it is not, adjust the TCXO (IC700) to trim to meet the
requirement, preferably within 100Hz.
6.4.3.4 Low-Frequency Balance Adjustment
Note:
• PGM800Win version 3.00 or later must be used for T881 adjustments and can also
be used to adjust T857 and T837 units. Electronic potentiometer (256 step) is used
to allow channel adjustment of two-point modulation (Low freq. balance).
• PGM800Win version 3.00 or later must be used, if the unit serial number is longer
than 6 digits.
1. Apply the following settings to the IFR:
– Receiver mode and Oscilloscope display (Source Demod out connector, DC coupled).
– 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 procedure out-
lined in section 3.2.1.1.2.2. You can also run both programs on the same computer if two serial
COM ports are available.
4. Press EPOTs button. 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). Record the deviation read.

proceed to step 8.
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 section3.2.1.1.2.2. Record de-
viation 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 de-
viation produced between:
- 1000 Hz sine wave adjust tone and

section 6.4.5
- 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, Tait T839
service manual for T839 model or Tait T889 service manual for T889. Cable loss should be in-
cluded in the reading.
6.4.4.2 Forward Power Alarm Level
1. Power up the PA and adjust front panel power control (T889 or T839: RV109 and T859: RV63)
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 (T889 or T839: RV101and T859: RV48) so that the forward
power alarm LED lights.
3. Adjust front panel power control (T889 or T839: RV109 and T859: RV63) for the normal oper-
ating power level
120 20170-204a ParagonPD Technical Manual

6.4.4.3 Reverse Power Alarm Level (Optional)
1. Power up the PA and adjust the front panel power control (T889 or T839: RV109 and T859:
RV63) for the normal operating power level.
2. Connect an unterminated 3dB 150 W pad to the PA output (e.g. 3:1 VSWR) and adjust the re-
verse power alarm set (T889 or T839: RV105 and T859: RV52) so that the reverse power alarm
LED lights.
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 29
Figure 29 - 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 (front panel power control) 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 cur-
rent, 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 current is re-
duced too far, maximum power output will drop and 2f rejection may degrade.

Appendix 1 - ParagonPD Deviation adjust
1. Using the WinRIS, 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.bp2). “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 WinRIS 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 the level is now correct, press StationReset to make the change permanent.
• Otherwise do step 5 again, changing the value entered in the file by 1 or 2 digit(s) up
or down, fine-tuning directly the Par85 (DSP deviation) parameter. Do steps 6 and 7
again to confirm acceptance.
This last step may have to be repeated once or twice while varying the entered value
up or down. If unable to obtain the correct level after editing up and/or down by no
more than 2, contact System Engineering.
