2. Installation 2.1 Overview The cabinet and rack-mount housing the Paragon-III’s radio assembly and the BDLC-III 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.

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).
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 resulting 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.
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.
3. Operating Description 3.1 Radio Assembly The Radio assembly component of each Paragon product is made up of high performance synthesized radio base station designed for single operation. The Radio Assembly’s modules are commonly installed in a standard, 19-inch wide rack frame.
The Exciter’s front panel controls and indicators are: Carrier Switch Exciter • Carrier Switch - momentarily keys the transmitter ON while pressed (used for test purposes only). • On LED - is lit when transmitting • Line Sensitivity – not used. • Supply LED - is lit when DC power is applied. Fast Flashes when linked with PGM800Win. Slow Flashes indicates VCO (synthesizer) out of lock. Unequal Flashes indicates internal communication error. • ® 3.1.
The speaker panel is fitted with a four-Ω speaker. Both series of radio assemblies share the same front panel fitted with an RJ11 connector. This connector is used to allow programming the radio from the front of the unit via a programming lead. This feature is exclusive to the Series II modules. If the speaker panel needs to be removed, a mirror programming port connector is provided on the backplane. ® 3.1.
3.1.5.1 Power Supply Rear Connections The rear connections (convection-cooled model shown; fan-cooled model not illustrated) for each of the power supply are: Fail Alarm – Off: Power supply OK; approx. +Vout (via 1k resistor - typ. 13.8V). ON: Power supply failure; approx. -Vout (via 11k resistors - typ. 0V) Fail Alarm Remote Sense Output 13.8V 15A Max. + Remote – Not used for Paragon - Sense – Not used for Paragon -VE – main ground (0V) +13.
4. Trouble-Shooting and Testing The checks described below should be done at time of installation, annual intervals, or whenever deterioration 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.
Table 3 - Checklist A (After installation) CHECKLIST A (Paragon-III) Recommended Check out after Installation Step ACTION 1 Normal Power-up Sequence 2 Connect and save unit config EXPECTED RESULTS at 25°°C MEASURE WITH IF NOT? BDLC-III beeps once, all LEDs come ON for about four seconds, the green LEDs then flash in a “ripple” pattern for close to two seconds. All LEDs go OFF except the CK that should flash 6 to 8 times per second.
Table 4 - Checklist B (General) CHECKLIST B (Paragon-III) General Check out (part1 of 2) Paragon-III units are set and characterized at the factory to optimize performances. It is not recommended to try readjusting units unless it is really required. Misadjusting a unit may result in significant performance losses. The proposed adjustments in the "IF NOT?" column below, should be tried ONLY if system data performance degradation is noticed combined with out-of-tolerance items.
CHECKLIST B (Paragon-III) General Check out (part2 of 2) Paragon-III units are set and characterized at the factory to optimize performances. It is not recommended to try readjusting units unless it is really required. Misadjusting unit may result in significant performance losses. The proposed adjustments in the "IF NOT?" column below, should be tried ONLY if system data performance degradation is noticed combined with out of tolerance items.
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.
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.

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.
5.2 Series II Radio Tuning - This section covers the basic Series II base station 700MHz radio modules radio tuning and verification. Note: Usually, this section is never done unless called for in section 5.1 “Series II - Radio Programming” or in Table 4 - Checklist B (General)“Checklist B” (General). 5.2.1 Test Equipment - Digital Multimeter & probes (e.g.
- 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.
5.2.2.5 RSSI Adjustment - Caution: mis-adjusting RSSI may reduce the Paragon-III's Parallel Decode (PD) performance. - BDLC-III must be connected to the radio chassis assembly during this process. 1. T885-xx-0200 (700MHz) receivers: - Refer to Figure 17 - T885-0200 Receiver Tuning Controls location - 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 ±6kHz. - Adjust RV 345 (RSSI level) for T885 to give 2.
5. Connect a 3 feet long double shielded cable (N-M to BNC-M) between the IFR T/R output and the exciter antenna connector. 6. Connect the Paragon-III Extender Rail Kit to the empty chassis exciter slot. 7. Apply power to the base station. 5.2.3.2 Synthesizer Alignment 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.
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.
