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 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 smallparts kit or with one end fastened to the equipment. For each of the power supply modules: 1. Fit one end of the grounding lead’s pushon connector onto the grounding tab. For the Radio Assembly chassis: 1. Install the grounding lead’s lug over the binding post and firmly hand-tighten the binding-nut. 120 20170-302 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. Press both red power buttons located on the front of the module to have complete power distribution to the Radio assembly. The power supply front panel LEDs indications are: Table 1 - Power Supply LEDs Indications LED On Stby OL On & OL Color Green Red Steady Red Flashing green and red respectively Indication Power enabled * Power disabled * Current Overload Over voltage * To remove voltage from the power supply PCB, disconnect the main power cords. For LEDs descriptions, see section 3.2.1.5 The Radio assembly is fused at the rear of the chassis: • Fuse 1 is a 32-volt MDL (slow-blow) 10A • Fuse 2 is a 32-volt MDL (slow-blow) 30A Note: the fuses form factor and their locations may differ from Figure 3. ParagonPD Technical Manual 2.3.2 BDLCPD assembly Power 2.4.2 Cabling and Connection PD The BDLC assembly uses a standard 120 VAC power cord. Plug this cord to the rear power outlet shown in Figure 4 and Figure 5. 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 ParagonPD 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. To check or install a fuse: 1. Open the slide-out fuse drawer located below the power connector by using a fine bladed screwdriver or a knife blade and gently pry open. 2. Hold the fuse support in one hand and with the other, lift the center plastic retainer until it releases the fuse sliding base. 3. Replace or install a 250V, 2A fuse. 4. To complete the procedure, push the sliding fuse base until it snaps under the retainer. 5. Re-insert the fuse drawer in its housing and push until it is fully seated and closed. When ready to apply power, use the ON-OFF toggle power switch adjacent to the power connector. Caution: When terminating RF cables use brand-name crimping tools (such as AMP, Jensen, CrimpMaster, etc…) of the correct size for the cable and type of connector used. Common pliers are NOT acceptable. 2.5 Completing the physical Installation. PD Paragon products are factory-configured to user’s requirements and are shipped ready to run. ON-OFF Switch After new installations: 120VAC Connector Fuse Slide-out Drawer Use only with a 250 V fuse Employer u niquement av ec un fusible de 250 V Figure 5 - BDLC ’s rear connection, switch, and fuse Antenna • Check that fuses are inserted. • Turn both BDLCPD and radio power ON. Any change(s) to the settings must be done via files saved on diskette and loaded into the unit using the WinRIS program. 2.4.1 Overview PD Paragon 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.

ParagonPD Technical Manual 3.2.1.4 3.2.1.5 LEDs and Indications RS-232 LED Function Selection 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 green • RS-232 Group, displays serial port status in green except the TX LED that also uses red • ALARM Group, displays fault status in red 3.2.1.5.1 Radio Network Indicators The Radio Network LEDs are useful when troubleshooting as an indication of network activity. It can help isolate transmission problems.

Test transmission display is done in red. Once the desired RS-232 LED function is selected, stop pressing PF1, allow the two-seconds timer to run down. The BDLCPD returns to normal operation using the newly selected display. 120 20170-302 15 ParagonPD Technical Manual 3.2.1.5.2 RS-232 Port Indicators Blinking slowly (1 cps), indicates the parameters contents of the flash memory have been corrupted. The unit automatically loads its set of factory default parameters and starts beeping at 20 seconds intervals. The RS-232 LEDs normally indicate port activity on the port selected. See section 3.2.1.4 above for instructions for selecting display mode.

It lights ON and OFF while being configured. FR Flow Control on Receive - the BDLCPD has received a flow control signal from the device connected to it. When it lights, BDLCPD has stopped sending data to the DTE. When LED goes out, the port terminal is again ready to receive data. FT RD TD CK LM RM LF UF ALARMS Figure 14 - ALARMS LED indicators LM PD Flow Control on Transmit - the BDLC has sent a flow control signal to the DTE asking it to stop sending data. The LED remains lit as long as the terminal is being held off. - Out of buffers. No memory available to accept data from a local terminal device. Usually denotes a flow control problem. - Flash memory error. At power-up or reset, the unit detected a change in nonvolatile memory. RM Transmit Data - shows the status of Transmit Data pin 2 of the RS-232 interface. When lit, the DTE is sending data to the BDLCPD. Check and Power LEDs Check: Normally flashing rapidly (about 6 cps), indicates microprocessors are working correctly and power is applied. Remote Minor Alarm - when lit, indicates any of the Local Minor Alarm listed above have taken place at the remote end of the link (i.e. the mobile the local base station is currently communicating with). It will also light when a protocol error has been detected on the network. In a network using the “Host Link Active” (MSC) feature, the RM LED, flashing in-sync with the CK LED, indicates that the link is down. Not flashing indicates unit is not functioning. 120 20170-302 Local Minor Alarm - when lit, indicates the presence of any of the following minor faults: - Parity, framing or overrun error at any RS-232 port. Receive Data - when lit, it shows that the Receive Data pin 3 on the RS-232 interface connector is active. Since all BDLCPD are configured as DCE, it means that the DTE is receiving data from the BDLCPD. 3.2.1.5.3 Alarm Indicators All alarm conditions will cause the BDLCPD to light one or more of the LED indicators. LEDs remain ON when lit until cleared by either pressing PF 1 (without affecting operation of the unit) or RESET (cycling unit OFF and ON). Figure 13 - RS-232 Port LED indicators CM re- LF 16 Link Failure - when lit, indicates that the base station fails to receive an ACK for a ParagonPD Technical Manual packet sent and for all subsequent retries. Some data has possibly been lost. LF is not functional if all active ports are set to NAR mode. • Link fails are inevitable during normal operation (mobiles temporarily out of range, in a tunnel, parked in a dead spot, etc.). A lit LF LED is not normally cause for concern. 3.2.2.1 RS-232 Signal Levels In the description of data signals in Table 7, the following conventions are used: Table 5 - RS-232 Signal levels UF Unit Failure - when lit, the unit requires attention: - The BDLCPD is not operable; It may indicate detection of a system software error trap. - The BDLCPD is operable; Indicates that on power-up, invalid data was detected in the serial EEPROM chip (located in the radio modules). It may also indicate that connection to the radio modules is incorrect or that radio power is not applied. The LM, RM and UF alarms also sound a beep when a fault occurs. The LF alarm is silent.

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 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 UHF = ± 2.5 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 T800-01-0002 programming cable (DB-25 to RJ-45 cable) Standard 25-pin parallel cable (terminated Male/Female) 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 frontmounted 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: - 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. 120 20170-302 3. Program required channel's frequencies. – Do not program any CTCSS tones on channels. – Do not change any other parameters. – Refer to Figure 17, Figure 18, Figure 19 and Figure 20 for screen program examples. 4.

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: 16 32 64 Always ON except when default channel is required CHANNEL SWITCH RX CHANNEL SWITCH TX Binary Value Figure 21 - Backplane DIP switches example - Channel 5 selected 120 20170-302 27 ParagonPD Technical Manual 5.2 Series II Radio Tuning This section covers some basic Series II base station modules radio tuning and verification for: - VHF (T83x-xx-0200), - UHF (T85x-xx-0250) and - 800 MHz/900 MHz (T88x-xx-0200).

Apply power to the Paragon . 5.2.2.2 Synthesizer Alignment Single channel: Connect the Multimeter to either side of L504 (T885) or the long lead of L1 (T855 and T835) in the VCO (this measures the synthesizer loop voltage). 1. T885 (800/900 MHz) Tune VCO trimmer CV500 for a synthesizer loop voltage of 10VDC. 2. T855 (UHF) Tune VCO trimmer C6 for a synthesizer loop voltage of 10V DC. 3. T835 (VHF). Tune VCO trimmer CV1 for a synthesizer loop voltage of 9VDC. Multiple channels (adjusting as shown for single channel above): 1. 2. 3. 4. 120 20170-302 T885 (800/900 MHz) Adjust the VCO loop to 10V using the middle frequency channel. T855 (UHF) Adjust the VCO loop to 10V using the middle frequency channel. T835 (VHF) Adjust the VCO loop to 9V using the middle frequency channel. 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 respectively for the T885 and T855 or within 13V and 5V for the T835. 29 ParagonPD Technical Manual 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. 120 20170-302 30 ParagonPD Technical Manual 5.2.2.5 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.

For sets with serial numbers following 217262, set RV69 (driver power level) fully clockwise. 2. For all units, preset the tuning controls as shown in Figure 25 Figure 25 - T859 Tuning Settings 3. 4. 5. 6. 7. 8. 9. 10. 11. Set RV63 (front panel power control) fully clockwise. Key on the exciter (press PTT button). Adjust CV1 for maximum output. Adjust CV8 for maximum output. Adjust CV32 for maximum output. Adjust CV51 and CV57 for maximum output. Adjust CV34 and CV35 for maximum output. Recheck all settings. The power output should exceed 110W. For sets with serial numbers following 217262, adjust RV69 (driver power level) until the output power drops to 110W. 12. For all units, adjust RV63 (front panel power control) to reduce the power output to the required level (normally 100W). 5.2.4.5 Tait T859 Tuning for Best Efficiency 1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply red wire and its 13.8Vdc output, then connect the shunt to the multimeter (VDC scale) 2. While transmitting, monitor the current. It should remain under 22A. 120 20170-302 35 ParagonPD Technical Manual 3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply current, but do not exceed a maximum drop of 0.5A per control. 4. Check that the supply current is <22A for 100W output power. Note: These control settings are normally very close to minimum supply current. If the current is reduced too far, maximum power output will drop and 2f rejection may degrade. 5.2.5 (TPL) LMS series Power amplifier (PA8-2BF-LMS) (890-960 MHz) Note: Refer to Figure 26 for parts location. 5.2.5.1 Do not re-install the Exciter module back in the ParagonPD rack frame.

Warning: Do not drop the power to less than 65 Watts. Setting a lower value may create spurious emissions that can create interference with adjacent channels. 5.2.5.2 a) b) c) d) 5.2.5.3 Forward Power Alarm Level Key the transmitter using the Exciter Carrier button Adjust T881's RV502 Exciter output power to drop the RF power amplifier output to 65 Watts. Adjust TPL's VR5 until the front panel LED begins to flash. Adjust T881's RV502 (Exciter) output level to the normal operating power level. Amplifier Activation a) Key the transmitter using the Exciter Carrier button b) Set T881's RV502 Exciter output power to a level 6 dB below the normal drive level. (e.g. divide by 4 the Exciter nominal output power) Refer to 5.2.3.5 Exciter Power Output. c) Adjust TPL's VR4 to activate the amplifier and its fans at this threshold. d) Adjust T881's RV502 Exciter output level for the normal operating power level. 5.2.5.4 RF Input (Relative Reading) a) Toggle the front panel switch until the top line of the display reads RF INPUT. b) Key the transmitter from the T881's Exciter Carrier button c) Adjust TPL's VR8 to a nominal 10 units at nominal input drive 5.2.5.5 Forward Power meter calibration a) Toggle the front panel switch until the top line of the display reads FWD PWR. b) Key the transmitter from the T881's Exciter Carrier button. c) Adjust TPL's VR6 so that the front panel meter is in agreement with the calibrated power meter. 5.2.5.6 Reverse Power meter calibration a) Connect an unterminated 3dB pad to the PA output (e.g. 3:1 VSWR). 120 20170-302 ParagonPD Technical Manual 36 b) Toggle the front panel switch until the top line of the display reads RFL PWR. c) Key the transmitter T881's Exciter Carrier button. d) Adjust TPL's VR7 so that the front panel meter is in agreement with the calibrated power meter. 5.2.5.7 Reverse Power Alarm Level a) Connect an unterminated 3dB pad to the PA output (e.g. 3:1 VSWR). e) Key the transmitter T881's Exciter Carrier button. b) Adjust TPL's VR3 until the front panel SWR LED begins to flash Note: The LED should extinguish when the normal load is connected (connected to IFR).

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. 120 20170-302 44 ParagonPD Technical Manual 6.
