Packaging
2. Installation
Each ParagonPD product normally leaves the
factory packaged as follows:
•
A Series II Dataradio base station “Radio
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 assembly.
2.1
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. 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 secure
electrical and mechanical connection is
achieved.
If a –DC rail (0V) is installed as part of the system, the grounding leads may alternatively be
fitted to the rail terminal.
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 their 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

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

All receiver procedures detailed in this section should be done twice: once for the “Main” (or RX1) receiver module and a second time for the “Auxiliary” (or RX2) receiver module. Connect to the relevant
module and its corresponding backplane PCB as required.
5.1
Series II Radio Programming
This procedure describes the steps needed to program the ParagonPD base station UHF, VHF &
800MHz radios (half & full channels).
Receiver VCO and front-end alignment will be
required when new receiver frequency is programmed outside the radio tuning range:
5.1.1 Recommended Items
800/900 = ± 3.0 MHz from previous center
frequency
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

RJ-45 cable)
Standard 25-pin parallel cable (terminated
Male/Female)
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: ± 4 MHz from previous
center frequency.
1. Connect the PC, via the supplied programming
lead, to the speaker panel’s front-mounted
RJ11 connector.
5.1.2 Module Programming
Before starting programming, have a PC running
MS-Windows © and the Tait PGM800Win software for Series II Base station.
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.
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:

5.1.3 Channel Selection via DIP
Switches
The backplane-mounted DIP switch settings
override the default channel programmed by
PGM800Win.
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”.
To set a default channel via the software, all DIP
switches must be set to “OFF” (i.e. 00000000).
It is recommended to set both SW1 (RX) and
SW2 (TX) to the same settings on both back
plane boards.
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.
Example: To select channel 5, set the DIP
switches as shown below:

5.2.2.3 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 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. The absolute
minimum requirement level to reach is -108dBm (typical level is -109 to -110 dBm)
4. Perform the SINAD linearity tests described in paragraph 5.2.2.4. If it fails to pass the requirement,
contact your Dataradio technical support.
WARNING: Do NOT attempt to re-tune the IF stages
(I.e. 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 ISI coefficient settings and may reduce significantly the radio performances over data.
5.2.2.4 SINAD and Linearity Check
1. Apply the following settings to the IFR COM-120:
a)
b)
c)
d)
e)
Generator mode, Output T/R, 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.
Set deviation to ±3.0KHz for full channel or ±1.5KHz for half channel radios.
Use a X1 scope probe connected to the IFR SINAD input and monitor the Discriminator O/P on the
radio 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 should be better than -108dBm (including cable loss).
3. Offset the IFR TX frequency 2kHz (full channel) or 1kHz (half / NPSPAC channel) above the main
radio RX frequency, record the SINAD reading. It should remain within 1.5 dB 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 / NPSPAC channel) below the main
radio RX frequency, record the SINAD reading. It should remain within 1.5 dB 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.

RSSI Adjustment
- Caution: mis-adjusting RSSI may reduce the ParagonPD's Parallel Decode (PD) performance.
- BDLCPD must be connected to the radio backplane during this process.
1. T885-xx-0200 (800/900 MHz) and T855-xx-0250 (UHF) receivers:
- Apply an on-channel signal from the RF generator at a level of -110 dBm modulated by a 1 kHz tone at
a deviation of ±3kHz (full channel) or ±1.5kHz (half / NPSPAC channel).
- Adjust RV 345 (RSSI level) for T885, RV320 (RSSI level) for T855 to give 2.0V RSSI output at
SK330 pin 2 (T855) or on backplane SK1 pin 5 when measured with a voltmeter (See Figure 24 for test
point location).
2.
T835-xx-0200 (VHF) receivers:
Apply an on-channel signal from the RF generator at a level of -100 dBm with deviation of ±3kHz
(full channel) or ±1.5kHz (half channel) at 1kHz tone.
Adjust RV320 (RSSI level) to give 4.5V RSSI output at RSSI test point (near quad. Coil L360) or on
backplane SK1 pin 5 when measured with a voltmeter (Figure 24 - T800-50-0001) for test point location).

the BDLCPD’s PF1 button and following the procedure outlined in section3.2.1.3. Record deviation again.
7. The difference in deviation between the two channels should be less than ±300Hz. If not, readjust 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 test tone and Random data test pattern
The difference between the test tone and the test pattern should be:
< 600 Hz (DGMSK)
< 1.5 kHz (xSR4FSK, HC)
< 2.0 kHz (xSR4FSK, FC/NPSPAC).
For multi-channel unit, repeat this step on the highest frequency channel.
9. 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 3.2.1.3. Make sure that
deviation level read on the IFR correspond to model and bit rate in use (see Figure 16). Re-adjust

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.
