2.5 Electrical
Standard 120 VAC electrical power is required. It should be capable of providing at least 10A to power
Paragon-III (<6A) and ancillary equipment.
2.5.1 Paragon-III Assembly Power
Two distinct power configurations (rear views) are shown in the preceding pages. They are:
• Paragon-III Base Station Standard Assy (Figure 3).
This configuration is described in paragraph 2.5.1.1 below.
• Paragon-III Base Station Assy. with 3rd party DC supply (Figure 4).
This configuration illustrates typical wiring variation required when using both a third-party
power supply and an optional DC-powered BDLC-III setup. Refer to Dataradio System
Engineering for further details.
2.5.1.1 Standard Power Supply Configuration
The Radio assembly unit receives 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 (the second one is
used as a spare):
• A T807 using convection cooling is rated to 15A nominal at 13.8VDC. It supplies all the radio
modules other than the Power Amplifier.
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, 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 connectors are supplied (either in the courtesy small-parts kit or
with one end fastened to the equipment.
• For each of the power supply modules, fit one end of the grounding lead’s push-on connector
onto the grounding tab.
• For the Radio Assembly chassis, install the grounding lead’s lug over the binding post and firmly
hand-tighten the binding-nut.
• For each power supply modules
1. 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.
2. Apply anti-corrosion compound where paint scraping was done.
3. 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 fit-
ted 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.

2.5.1.1.1 T808/807 DC Power Supply Connection & Torque Settings
Warning: Securing the DC Power Supply cable into the DC connector to provide a good electrical
connection is essential. Over time, the wires tend to compress in the DC connector re-
sulting in an increasingly poorer connection. Consequently, as high current is drawn,
the connector heats up increasing the resistance thereby causing still more heat until the
connector eventually burns up.
Although screws securing DC cables to the Power Supply terminals are tightened to the torque set-
tings given below prior to new system delivery, they must be re-tightened as part of the commis-
sioning process and re-tightening is also part of the regular maintenance schedule.
Prior to replacing a Power Supply module into an existing system, inspect the cable and re-terminate
the DC wires if the strands have previously been twisted together or show any sign of damage.
Cut the wire at the end of the insulation and then strip approximately .4 inch (10mm) of insula-
tion off the cable. DO NOT TWIST THE WIRE STRANDS. Insert the DC cable into the screw
terminal and tighten the screw to secure the cable as per the torque settings given below.
Torque Settings:
The manufacturer recommends torque setting all power supply terminal screws to:
• 0.5 to 0.6 Nm (or 4.5 to 5.3 In/lb or to .37 to .44 ft/lb)
Note: Dataradio uses a Sturtuvan Richmond 29-pieces adjustable torque screwdriver model
CAL36/4K.
After tightening, pull on the cable to check the cable is secured tightly into the screw terminal.
2.5.1.1.2 Power Indications
• Press both red power buttons located on the front of the module to have complete power distri-
bution to the Radio assembly. The power supply front panel LEDs indications are:
Table 2 - Power Supply, LEDs indications

2.6 Antenna
2.6.1 Overview
Paragon-III 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.
2.6.2 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 Paragon-III 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 acceptable.
2.7 Completing the physical Installation.
Paragon-III 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 the radio-BDLC assemblies (antennas, PC, power
cords etc.)
• Check that fuses are inserted.
• Turn both BDLC-III and radio power ON.
You are now ready to check for normal operation (as per paragraph 2.8) and to run the Dataradio
CDip program for testing or trouble-shooting.
Any change(s) to the settings must be done via files saved on diskette and loaded into the unit using
the CDip program.
2.8 Checking out Normal Operation
1- Check that power is applied.
2- Check Radio assembly lights for proper operation as per section 3.1.1
3- Check for proper operation of the BDLC-III’s LEDs.
4- Using the CDip program and an in-line wattmeter, check forward & reverse power to confirm
main antenna installation
5- Using CDip, check the RF Data Link with a mobile that can be heard (as per section 4.3.1)
If user application and mobiles are available, test the installation by going through a normal sequence
of transmitting and receiving messages.

4. Trouble-Shooting and Testing
The checks described below should be done at time of installation, annual intervals, or whenever de-
terioration in performance is noted.
4.1 Equipment Required
• In-line watt meter (10 W range)
• Radio service monitor (IFR-120B with option 03: 30KHz IF filter or equivalent).
• RG-214 or RG-223 cable with N-Type male connector to connect Paragon-III to the service
monitor.
• CDip 1.0 or later1
Important note: Before proceeding make sure that the service monitor has been calibrated re-
cently and has warmed up for at least the time specified by its manufacturer.
Some reported frequency and deviation problems have actually been erroneous indications from
service monitors that have not adequately warmed up. This is particularly likely when field service is
done during winter months.
4.2 Recommended Checks
A) After an installation
1. LED Indications
2. Using CDip, Save “unit config” to a file
3. Transmitter Output Power
4. Transmitter Reflected Power
5. RF Link test between Paragon-III and mobile unit(s)
B) For annual maintenance & trouble-shooting
Same checks as A) plus:
6. Carrier Frequency Error
7. TX Deviation
8. Low Frequency Balance
9. 12 dB SINAD
10. Receiver distortion
11. RSSI check
12. Verify power supply connections & terminals torque settings (see paragraph 2.5.1.1.1)

4.3 Additional test details
4.3.1 RF Data Link Test
A link test between a mobile and a known base station can be done using the CDip "Address" and
"Send" functions. The “Address” and “Device” fields, the “Send” button and the “Chat” message
screen are used to send messages to specific mobile or base or to carry out RF test. Start by entering
the address of the mobile (or base station) you wish to send a test message to or test:
1- Specify the address:
Addresses may be entered by typing directly in the “Address” field in two ways:
- Numerically, the valid address range is 1-126.
- As an “Alpha-Mapped-Nibble” (AMN) address, consisting of upper case letters in the range
A-P.
The valid address range is A to GN.
- The base address is usually: 1.
- The program may display one of the following messages on the status bar:
- For Paragon-III products:
“address is not in AMN or number format”
- For mobile products:
“address is not in the range A – GN”
In either case, check that the address entered is within the acceptable range, is of a valid format
and correctly typed.
2- Enter the Device number for mobile (or base station).
3- Press the Send button.
The Chat window reports “Sent to xx mobile” (where xx is mobile name).
If test is successful:
Status line reports “Delivery confirmed.
If test unsuccessful:
Chat window reports “Waiting”,
Then the Status line reports “Delivery Failed”.

5. Radio Programming and Adjustments
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 Paragon-III radio base station 700 MHz.
5.1.1 Recommended Items
- 486 PC or better, MS-Windows 98 © or later
- T800win programming kit for Series II:
- PGM800Win programming software user's manual
- PGM800Win Windows based programming software version 3.0 or later
- T800-01-0002 programming cable (DB-25 to RJ-45 cable)
- Standard 25-pin parallel cable (terminated Male/Female)
5.1.2 Module Programming
Before starting programming, have a PC running MS-Windows © and the Tait PGM800Win soft-
ware 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 pro-
grammed outside the radio tuning range:
792-794 MHz = ± 3.0 MHz from previous center frequency
797-803 MHz = ± 3.0 MHz from previous center frequency
• Exciter 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.
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 11, Figure 12, Figure 13 and Figure 14 for screen program examples.
4. Save the base station programming info to a file for further reference.

5.1.3 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”.
Example: To select channel 1, set the DIP switches as shown below:

5.2.2 Receiver module
Note 1: Refer to Figure 17 (T885)
Note 2: When the synthesizer is unlocked, the front panel green LED called "Supply" will flash
indicating that it needs re-tuning.
Warning,
The LED will also flash when the unit is in setup mode while connected to the
PGM800win program.
5.2.2.1 Initial Setup
This initial setup will be used during all receiver alignment procedures described below:
1. Remove the receiver (T885) module from the Paragon-III rack frame
2. Remove the receiver top cover (nearest the handle).
3. Connect the Paragon-III Extender Rail Kit for Series II to the empty chassis receiver slot.
4. Prepare the Multimeter to DC Volts.
5. Apply power to the Paragon-III.
5.2.2.2 Synthesizer Alignment
Single channel: Connect the Multimeter to either side of L504 (T885) in the VCO (this measures
the synthesizer loop voltage).
120 20191-001 Paragon-III Technical Manual

- T885 (800/900 MHz) Tune VCO trimmer CV500 for a synthesizer loop voltage of 10VDC.
Multiple channels (adjusting as shown for single channel above):
1. T885 Adjust the VCO loop to 10V using the middle frequency channel.
2. 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 for the T885.
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 turn-on 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 back-
plane at SK1 pin 6 (RX-audio1). Alternately, it is also possible to monitor at the receiver I/O Pad
P207 (T885).
2. Adjust the helical resonators for best SINAD: #H400, #H401 and #H900 (T885).
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)
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 signifi-
cantly the radio performances over data.
5.2.2.4 SINAD and Linearity Check
1. Apply the following settings to the IFR COM-120:
a) Generator mode, Output T/R, TX frequency to match the main radio RX frequency
b) Filter set to wide band (no audio filter)
c) Select Gen2 (Modulating tone fixed to 1KHz). All other Gen must be off.
d) Set deviation to ±3.0KHz for full channel or ±1.5KHz for half channel radios.
e) 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).
2. Lower the RF level to get a 12dB SINAD reading. Level should be better than -108dBm (including ca-
ble loss).
3. Offset the IFR TX frequency 2kHz above the main radio RX frequency, record the SINAD reading. It
should remain within 1.5 dB from the on frequency SINAD reading.
4. Offset the IFR TX frequency 2KHz below the main radio RX frequency, record the SINAD reading. It
should remain within 1.5 dB from the on-frequency SINAD reading.
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.

Single channel: Connect the Multimeter to either side of L309 (T881).
- T881 (700 MHz) Tune VCO trimmer CV300 for a synthesizer loop voltage of 10V DC.
Multiple channels (adjusting as shown for single channel above):
- T881 (700 MHz) Adjust the VCO loop to 10V using the middle frequency channel.
All channels should lie within the upper and lower limits of 16V and 3V respectively for the
T881.
Note: Normally, the fast TX key option is installed and the synthesizer is always ener-
gized. In the case where that option was not fitted, key the transmitter by pressing
the front panel Carrier button to make the above adjustment possible.
5.2.3.3 TX Frequency Error Adjustment
1. Apply the following settings to the IFR:
- Receiver mode
- IFR RX frequency to match the main radio TX frequency
- IF Filter set to 30KHz
- Zoom the RF Error window: select 10Khz range
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 (IC700) to trim to meet the
requirement, preferably within 100Hz.
120 20191-001 Paragon-III Technical Manual
28
5.2.3.4 Low-Frequency Balance Adjustment
Note:
• PGM800Win version 3.00 or later must be used. 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, refer to Figure 14)
3. Transmit a square wave by using CDip (using a second serial port).
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.
5. For single-channel unit, proceed to step 8.
6. For multi-channel unit, select the highest frequency channel. Transmit a square wave via CDip.
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 de-
viation 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 less than 1.9 kHz for
xRC16FSK modulation set
For multi-channel unit, repeat this step on the highest frequency channel.
9. Select the active channel. Transmit a TX ON (Modulated) adjustment tone via CDip. Make sure
that deviation level read on the IFR correspond to bit rate in use (see Table 4 at step 6). Re-adjust
deviation as necessary.
5.2.3.5 Exciter Power Output
1. Apply the following settings to the IFR:
- Receiver mode, Output T/R
- IFR RX frequency to match the main radio TX frequency
- IF Filter set to 30KHz
- Select auto range in the Power reading window
- Connect the coaxial cable from the IFR T/R to the Exciter output connector
2. Key the Exciter by pressing the module PTT button. The output power at the coaxial cable end
connecting to the power amplifier should be:
