2. Installation
2.1 Overview
The cabinet and rack-mount housing the Paragon-III’s radio-modem and Power Amplifier 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 mo-
dem, and host PC or portable computer. Details of these are outside the scope of this manual. This
manual covers the radio-modem assembly and the power amplifier.
2.2 Location
Be sure to place the Paragon-III 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.

2.5 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 Assembly.
This configuration is described in paragraph 2.5.1.1 below.
•Paragon-III Base Station Assy. with 3rd party DC supply.
This configuration illustrates typical wiring variation required when using both a third-party
power supply and an optional DC-powered BSC setup. Refer to Dataradio System Engineering
for further details.
2.5.1.1 Standard Power Supply Configuration
The Radio assembly unit receives 13.8 VDC power inputs from two “T809 ” power supply modules
powered at 120 VAC. Normally used at room ambient temperatures, it can operate within its specifi-
cations 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. 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.
•For the Radio Assembly chassis, install the grounding lead’s lug over the binding post and firmly
hand-tighten the binding-nut.
•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 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 commission-
ing 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 .43 inch (11mm) 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.

120 20191-100a Paragon-III User Manual
9
Torque Settings:
The manufacturer recommends torque setting all power supply terminal screws to a minimum of:
•1.5 Nm (or 13.28 In/lb or to 1.107 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
Both red-colored translucent power switches located on the front of the power supply modules illu-
minate when AC power is available. Toggle both to ON to distribute power to the Radio Assembly
and to the Power Amplifier. The LED immediately below the switches light green indicating normal
DC power operation.
2.5.1.2 Backplane Fuses
Blade fuses (Maxi-Fuse) are used on the Radio assembly backplane (see Figure 7):
Dimensions – Inch (mm)
Fuse Type A B C
Maxi-Fuse 1.15 (29.21) 1.35 (34.29) .35 (8.89)
Fuse # F1 F2 F3
Values 10A 15A* 15A*
* Always replace the two 15A fuses as a pair.
Figure 7 - Maxi-Fuse
2.6 Power Amplifier
Although the T809-10 is a high efficiency switched mode power supply, a considerable amount
of heat is generated during normal operation. While in use, ensure that an adequate flow of
cooling air is able to circulate around the power supply, and that the air intake vents on the rear
and sides of the unit are not inadvertently covered.
Caution:
Do not operate this unit in a completely enclosed cabinet.
Refer to Figure 4 on page 6 for the location of DC power and RF in and out connectors.
Connect the T881 Tx module output to the power amplifier’s input using the Dataradio (p/n 727
03468-001) RG223 provided cable.
For the power amplifier output, Dataradio recommends a 50-ohm, low-loss, double-shielded
grade RF cable such as RG214 or 1/4" Heliax.
Power adjustments can be made using the front panel trim potentiometer. Dataradio does not
recommend setting an output lower than 35 watts.

2.7 Antenna
2.7.1 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.
2.7.2 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 (top) and RX-2 (bottom) cable-ends at the SDR module rear position with N-
type connectors.
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.
2.8 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-modem assemblies (antennas, PC, power
cords etc.)
•Check that fuses are inserted.
•Turn power supplies ON.
You are now ready to check for normal operation (as per paragraph 2.9) 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.
2.9 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 BSCs 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 5.3.1)
If user application and mobiles are available, test the installation by going through a normal sequence
of transmitting and receiving messages.
