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 sup-
ply 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 result-
ing 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 .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 distribu-
tion to the Radio assembly. The power supply front panel LEDs indications are:
Table 2 - Power Supply, LEDs indications
LED Color Indication

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 se-
lected 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.

3.1.7 Radio Backplane Assembly
A single PCB backplane is used. The main components are:
•RJ11 connectors (J11, J12) – connects to the Speaker panel front RJ11. Used for program-
ming the Radio modules.
•DB-25F port to ancillary equipement
•One channel-select DIP switch (SW1)
•Cooling fan driver – TB 3 located on backplane connects to the horizontally-mounted fan on
top of the Radio assembly and activated by BDLC’s PTT signal (setting JP1 2-3 will power
the fan continuously).
•30 A Fuse (F2 & F3) – two blade fuses (15ADC) in parallel are used for future Power ampli-
fier
•10 A Fuse (F1) – one blade fuse to power the other base station components (receivers, ex-
citer and optionally the BDLC).
