1.5.2 Model Designation
To correctly identify your ParagonPD unit, check its catalog number label located on the rear of the
BDLCPD adjacent to the power connector.
The first four digits designate the model:
BDDD = ParagonPD (DGFSK)
BDD4 = ParagonPD (SRRC4FSK)
The next digit designates the transmitter power:
- 005 = 5 watt transmitter
- 070 = 70 watt transmitter (850-870 MHz
only)
- 100 = 100 watt transmitter
The next and last digit designates the Power
Source:
- 0 = Power supply deleted on order
- 2 = heavy-duty 120 VAC dual supplies
The next three digits designate the Band used:
- 83X = VHF, 100W
- 85X = UHF, 100W
- 88X = 800 MHz, 70W
The next digit designates the RF band of operation:
For the 83X band:
- 1 = 136 – 156 MHz
- 2 = 148 – 174 MHz
For the 85X band:
- 1 = 400 – 440 MHz
- 2 = 440 – 480 MHz

Overview
The cabinet and rack-mount housing the ParagonPD’s Radio assembly and the BDLCPD is
generally installed in a sheltered facility. Occasionally 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. Details of these are outside the scope of this manual. This manual covers the radio assembly and
the BDLCPD that includes the modem.
2.2
• 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 immediately.
Location
Be sure to place the ParagonPD in such a way
that:
•
The LEDs can be seen (as an aid in troubleshooting)
•
Access to the antenna connector and to the
back connectors is possible without removing 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 equipment.

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 typically rack-mounted right below the main assembly 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 connected to ground via their individual, rearconnected, 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 connectors 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 handtighten the binding-nut.
120 20170-201
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.

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.

Flow Control on Transmit - the BDLC
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.
LM
- Out of buffers. No memory available
to accept data from a local terminal device. Usually denotes a flow control
problem.
- Flash memory error. At power-up or
reset, the unit detected a change in nonvolatile memory.
Transmit Data - shows the status of
Transmit Data pin 2 of the RS-232 interface. When lit, the DTE is sending
data to the BDLCPD.
RM
Check and Power
Check:
Normally flashing rapidly (about 6 cps),
indicates microprocessors are working
correctly and power is applied.
Remote Minor Alarm - when lit, indicates any of the Local Minor Alarm
listed above have taken place at the remote end of the link (i.e. the mobile the
local base station is currently communicating with). It will also light when a
protocol error has been detected on the
network.
In a network using the “Host Link Active” (MSC) feature, the RM LED,
flashing in-sync with the CK LED, indicates that the link is down.
Not flashing indicates unit is not functioning.
Blinking slowly (1 cps), indicates the
parameters contents of the flash memory
have been corrupted. The unit automati120 20170-201
Local Minor Alarm - when lit, indicates
the presence of any of the following minor faults:
- Parity, framing or overrun error at any
RS-232 port.
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.

LF
Link Failure - when lit, indicates that the base station fails to receive 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.

Important note:
The aggregate total baud rate for all active ports on a BDLCPD must not exceed 30,000 for ParagonPD. 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 program
The Windows Radio Installation Software
(WinRIS) program is used to:
•
Check and troubleshoot ParagonPD.
•
Save an existing configuration.
4.2
GeminiPD’s and ParagonPD’s share a common
WinRIS 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) leading 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.
•
Upload files for field configuring of units
(Requires intervention with technical support).
To run the program, you will need:
- A PC or portable computer running a 32-bit
MS-Windows application:
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
Click on “OK”.
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
To connect and start
WinRIS
It is also possible to create a PC desktop shortcut icon for WinRIS:
•
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.
Operation
This support program can be run in MSWindows © mode.
DO NOT have more than one copy of this program loaded at any given time in separate windows. Doing so creates COM port sharing conflicts and failure to run the program alone results in unexpected transmissions.
Only left mouse button operation is supported.
Any command or selection shown in gray is either unavailable or is awaiting another action
before activating.

Banner Field
This field displays a string made up of the serial
number of the connected unit followed by the
firmwares used and their version number.
1- Type your password directly in the “Password” field. It is a string of 32 hexadecimal
characters (exactly).
Format is:
[serial number]:firmware 1 name, its version #,
firmware 2 name, its version #.
2- Press the button “Put Password” to make the
entry permanent. This field may be left
blank.
The serial number portion uniquely identifies
the unit. It is a variable length, maximum eightcharacter alphabetic string assigned at the time
of manufacture. It is identical to the serial number printed on the label of the unit. This number
cannot be changed and is used as part of the onair protocol.
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.
ParagonPD's firmwares reside in flash EPROM
and are designed to allow field upgrades.
Clearing a Password is done by entering 32 zeros.
When contacting your supplier, give the full
banner string and the version of the WinRIS
used. You will find the version number by selecting the “Help” menu option, then “About
WinRIS” command or pressing the “About”
button on the Toolbar.
The Dataradio supplied password algorithm is
designed to thwart the casual observer only. It
provides a limited form of data privacy. Therefore, if your security requirements are high,
Dataradio urges you to use external encryption

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 reprogramming. 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
“wideband”.
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

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 connector.
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.

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:

2. T835 (VHF) Adjust the VCO loop to 9V using the middle frequency channel.
3. All channels should lie within the upper and lower limits of respectively
All channels should lie within the upper and lower limits of 16V and 3V respectively for the
T855 and 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 TP314 (T855) or at the receiver IC350 pin 7 (T835).
2. Adjust the helical resonators for best SINAD: #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.
(minimum 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
requirement, contact your Dataradio technical support.
WARNING: Do NOT attempt to re-tune the IF stages
(i.e. L310 to L390 for T855, CV318 or L330 to L360 for T835).
These adjustments do not need to be re-adjusted after frequency reprogramming. Touching these coils will have a direct impact on the modem DSP coefficient settings 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 20170-201

ParagonPD Technical Manual
b) IFR TX frequency to match the main radio RX frequency
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 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 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 frontend. It still failed, contact your Dataradio technical support.
6.4.2.5
RSSI Adjustment (UHF: 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).
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 for test point location).
Vary the RF level and check the RSSI output voltage ( Figure 28):

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
channel 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 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 outlined 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. 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.
5. If transmission has not ended by itself, press BDLCPD PF1 to stop it. For single-channel
unit, 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 section
3.2.1.1.2.2. 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:
- 1000 Hz sine wave adjust tone and
- Random data
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.
Make sure that deviation level read on the IFR correspond to model and bit rate in use
(see Table 8 – Carrier deviations for Tone or Data Modulation). Re-adjust deviation as
necessary referring to the related Checklist (B for ParagonPD - page 27

6.4.4.1
6.4.4.2
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.
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.
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.

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 current
is reduced 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.

only)
- 100 = 100 watt transmitter
The next and last digit designates the Power
Source:
- 0 = Power supply deleted on order
- 2 = heavy-duty 120 VAC dual supplies
The next three digits designate the Band used:
- 83X = VHF, 100W
- 85X = UHF, 100W
- 88X = 800 MHz, 70W
The next digit designates the RF band of operation:
For the 83X band:
- 1 = 136 – 156 MHz
- 2 = 148 – 174 MHz
For the 85X band:
- 1 = 400 – 440 MHz
- 2 = 440 – 480 MHz
- 3 = 480 – 520 MHz
For the 88X band:
- 1 = 800 – 880 MHz (RX
850 – 870 MHz (TX)
- 2 = 870 – 960 MHz (RX)
(TX, 5W only)

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. Details of these are outside the scope of this manual. This manual covers the radio assembly and
the BDLCPD that includes the modem.
2.2
• 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 immediately.
Location
Be sure to place the ParagonPD in such a way
that:
•
The LEDs can be seen (as an aid in troubleshooting)
•
Access to the antenna connector and to the
back connectors is possible without removing 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 equipment.

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 typically rack-mounted right below the main assembly 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 connected to ground via their individual, rearconnected, 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 connectors 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 handtighten the binding-nut.
120 20170-201
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.

LEDs and Indications
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 manually changed or until RESET is
pressed or until power up.

Normally flashing rapidly (about 6 cps),
indicates microprocessors are working
correctly and power is applied.
Remote Minor Alarm - when lit, indicates any of the Local Minor Alarm
listed above have taken place at the remote end of the link (i.e. the mobile the
local base station is currently communicating with). It will also light when a
protocol error has been detected on the
network.
In a network using the “Host Link Active” (MSC) feature, the RM LED,
flashing in-sync with the CK LED, indicates that the link is down.
Not flashing indicates unit is not functioning.
Blinking slowly (1 cps), indicates the
parameters contents of the flash memory
have been corrupted. The unit automati120 20170-201
Local Minor Alarm - when lit, indicates
the presence of any of the following minor faults:
- Parity, framing or overrun error at any
RS-232 port.
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.

Important note:
The aggregate total baud rate for all active ports on a BDLCPD must not exceed 30,000 for ParagonPD. 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 program
The Windows Radio Installation Software
(WinRIS) program is used to:
•
Check and troubleshoot ParagonPD.
•
Save an existing configuration.
4.2
GeminiPD’s and ParagonPD’s share a common
WinRIS 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) leading 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.
•
Upload files for field configuring of units
(Requires intervention with technical support).
To run the program, you will need:
- A PC or portable computer running a 32-bit
MS-Windows application:
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
Click on “OK”.
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
To connect and start
WinRIS
It is also possible to create a PC desktop shortcut icon for WinRIS:
•
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.
Operation
This support program can be run in MSWindows © mode.
DO NOT have more than one copy of this program loaded at any given time in separate windows. Doing so creates COM port sharing conflicts and failure to run the program alone results in unexpected transmissions.
Only left mouse button operation is supported.
Any command or selection shown in gray is either unavailable or is awaiting another action
before activating.

Banner Field
This field displays a string made up of the serial
number of the connected unit followed by the
firmwares used and their version number.
1- Type your password directly in the “Password” field. It is a string of 32 hexadecimal
characters (exactly).
Format is:
[serial number]:firmware 1 name, its version #,
firmware 2 name, its version #.
2- Press the button “Put Password” to make the
entry permanent. This field may be left
blank.
The serial number portion uniquely identifies
the unit. It is a variable length, maximum eightcharacter alphabetic string assigned at the time
of manufacture. It is identical to the serial number printed on the label of the unit. This number
cannot be changed and is used as part of the onair protocol.
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.
ParagonPD's firmwares reside in flash EPROM
and are designed to allow field upgrades.
Clearing a Password is done by entering 32 zeros.
When contacting your supplier, give the full
banner string and the version of the WinRIS
used. You will find the version number by selecting the “Help” menu option, then “About
WinRIS” command or pressing the “About”
button on the Toolbar.

pass the requirement, contact your Dataradio technical support.
120 20170-201
34
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 reprogramming. 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
“wideband”.
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
1. Apply an on-channel signal from the RF generator at a level of -110dBm modulated by a
1 kHz tone at a deviation of ±3kHz (full channel) or ±1.5kHz (half channel).
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 and check the RSSI output voltage (Figure 28):
1) At –120 dBm: 1.2 VDC (+0.20 –0.45VDC)
2) At –90 dBm: 4.0 VDC (+0.20 –0.20 VDC)
3) At –80dBm: 5.0 VDC (+0.20 – 0.35VDC)

pressing the BDLCPD’s PF1 button and following the procedure outlined in section
3.2.1.1.2.2. 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 deviation produced between:
- 1000 Hz sine wave adjust tone and
- Random data
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.

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 connector.
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.

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:

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 TP314 (T855) or at the receiver IC350 pin 7 (T835).
2. Adjust the helical resonators for best SINAD: #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.
(minimum 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
requirement, contact your Dataradio technical support.
WARNING: Do NOT attempt to re-tune the IF stages
(i.e. L310 to L390 for T855, CV318 or L330 to L360 for T835).
These adjustments do not need to be re-adjusted after frequency reprogramming. Touching these coils will have a direct impact on the modem DSP coefficient settings 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

b) IFR TX frequency to match the main radio RX frequency
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 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 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 frontend. It still failed, contact your Dataradio technical support.
6.4.2.5

3. Transmit a square wave by pressing the BDLCPD’s PF1 button and following the procedure outlined 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. 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.
5. If transmission has not ended by itself, press BDLCPD PF1 to stop it. For single-channel
unit, 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 section
3.2.1.1.2.2. 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:
- 1000 Hz sine wave adjust tone and
- Random data
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.

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 current
is reduced 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.
