120 20170-302 ParagonPD Technical Manual82.3.1 Radio Assembly PowerReferring to Figure 3, the Radio assembly unitreceives two separate 13.8 VDC power inputsfrom a “T800 Slimline” dual power supply typi-cally rack-mounted right below the main assem-bly radio chassis.The T800 is made up of two separate power sup-ply units joined in a single chassis:• A T807 using convection cooling is rated upto 15A at 13.8VDC. It supplies all the radiomodules other than the Power Amplifier.• A T808 using convection and fan cooling israted up to 25A at 13.8VDC. It supplies onlythe Power Amplifier module.Normally used at room ambient temperatures,they can operate within their specifications over arange of –10 to +60 °C.Note: Internal over-temperature protection shutsdown the main transformer above 105degrees Celsius.Both power supply modules are internally con-nected to ground via their individual, rear-connected, seven-foot standard 120 VAC powercords. Nevertheless, each requires a separate se-cure electrical ground connection. Individualgrounding tabs are provided next to the powerconnectors.Similarly, the Radio Assembly chassis requires asecure ground connection. A threaded groundingbinding post fitted with a knurled binding-nut isprovided on the chassis next to DC input 2.Separate grounding leads with appropriate con-nectors are supplied (either in the courtesy small-parts kit or with one end fastened to the equip-ment.For each of the power supply modules:1. Fit one end of the grounding lead’s push-on connector onto the grounding tab.For the Radio Assembly chassis:1. Install the grounding lead’s lug over thebinding post and firmly hand-tighten thebinding-nut.For both A and B2. Fit the slotted connector (on the otherend of each of the grounding connector)under a conveniently located screw onthe rack frame or other support surface.Scrape away paint if needed to ensureclean contact.3. Apply anti-corrosion compound wherepaint scraping was done.4. Ensure by testing continuity that a secureelectrical and mechanical connection isachieved.If a –DC rail (0V) is installed as part of the sys-tem, the grounding leads may alternatively befitted to the rail terminal.Caution:Improper grounding between power supply caseand rack frame may result in harmful voltagepotentials and/or miscellaneous power supplyswitching noise problems in both receivers andtransmitter.Press both red power buttons located on the frontof the module to have complete power distribu-tion to the Radio assembly.The power supply front panel LEDs indicationsare:Table 1 - Power Supply LEDs IndicationsLED Color IndicationOn Green Power enabled *Stby Red Power disabled *OL Steady Red Current OverloadOn & OL Flashing green andred respectively Over voltage* To remove voltage from the power supply PCB, disconnectthe main power cords.For LEDs descriptions, see section 3.2.1.5The Radio assembly is fused at the rear of thechassis:• Fuse 1 is a 32-volt MDL (slow-blow) 10A• Fuse 2 is a 32-volt MDL (slow-blow) 30ANote: the fuses form factor and their locationsmay differ from Figure 3.
120 20170-302 ParagonPD Technical Manual92.3.2 BDLCPD assembly PowerThe BDLCPD assembly uses a standard 120 VACpower cord. Plug this cord to the rear power out-let shown in Figure 4 and Figure 5.To check or install a fuse:1. Open the slide-out fuse drawer located belowthe power connector by using a fine bladedscrewdriver or a knife blade and gently pryopen.2. Hold the fuse support in one hand and withthe other, lift the center plastic retainer untilit releases the fuse sliding base.3. Replace or install a 250V, 2A fuse.4. To complete the procedure, push the slidingfuse base until it snaps under the retainer.5. Re-insert the fuse drawer in its housing andpush until it is fully seated and closed.When ready to apply power, use the ON-OFFtoggle power switch adjacent to the power con-nector.Figure 5 - BDLCPD’s rear connection, switch, and fuse2.4 Antenna2.4.1 OverviewParagonPD commonly uses three antennas (onetransmit and two receive) unless a duplexer isused with one of the receive antennas; then onlytwo antennas would be needed. They should bemounted according to any guidelines suppliedwith the antennas. For antennas placement andspacing, consult System Engineering.2.4.2 Cabling and Connection1- Route good quality 50-ohm double-shieldedcoaxial cable(s) (e.g. RG-214 or Heliax) fromthe selected antenna position(s) to the Para-gonPD Radio assembly.2- Terminate the RX-1 and RX-2 cable ends atthe Receiver modules rear position with anN-type connector.3- Similarly, terminate the TX cable end at thePower Amp’s module rear position with anN-type connector.Caution:When terminating RF cables use brand-namecrimping tools (such as AMP, Jensen,CrimpMaster, etc…) of the correct size forthe cable and type of connector used.Common pliers are NOT acceptable.2.5 Completing the physicalInstallation.ParagonPD products are factory-configured touser’s requirements and are shipped ready to run.After new installations:• Re-check that all connections are secure onradio and BDLCPD assemblies (antennas, PC,power cords etc.)• Check that fuses are inserted.• Turn both BDLCPD and radio power ON.You are now ready to check for normal operation(as per paragraph 2.6) and to run the DataradioWindows Radio Installation Software (WinRIS)program for testing or trouble-shooting.Any change(s) to the settings must be done viafiles saved on diskette and loaded into the unitusing the WinRIS program.E mp l oye r u ni qu em ent av ecun fu sible de 25 0 VUse only with a 250 V fu seON-OFFSwitch120VACConnectorFuseSlide-outDrawer

Thisconnector is used to allow programming the radiofrom the front of the unit via a programminglead. This feature is exclusive to the Series IImodules.If the speaker panel needs to be removed, a mir-ror programming port connector is provided onboth backplanes.Figure 9 - Speaker panel3.1.1.5 Dual Power Supply moduleThe Dual Power Supply module is made up oftwo separate power supply units coupled in a sin-gle chassis.Refer to Table 1 on page 8 for tabular listing ofpower supply LEDs indicators.Refer to Figure 1 for the front panel LED layout.This module has:• Two “Power” red-colored pushbuttonswitches - Push in for ON and release out forOFF. Control complete power distribution tothe Radio assembly• Two “ON” LEDs - light green when pushbutton(s) is (are) ON; DC power is distrib-uted to radio modules. Flash green in con-junction with the “OL” LED (flashing red)when an over voltage condition is present.• Two “Stby”- Standby voltage LED, lights redwhen push button is off; AC power is appliedbut DC is not distributed to radio modules.To remove presence of voltage, disconnectboth power cords.• Two “OL” LEDs - Monitor current overload,light steady red when supply exceeds currentlimit set; nominally 25Amps (T808 model).Flashes red in conjunction with the ON LED(flashing green) when an over voltage condi-tion is present.3.1.1.5.1 Rear ConnectionsReferring to Figure 10, (convection-cooled modelshown; fan-cooled model not illustrated), the rearconnections for each of the power supply are:Fail Alarm –Off: Power supply OK; approx. +Vout (via 1kresistor - typ. 13.8V).ON: Power supply failure; approx. -Vout (via11k resistors - typ. 0V)+ Remote – Not used for Paragon- Sense – Not used for Paragon-VE – main ground (0V)+13.8V – Mains DC output supplyFigure 10 - Dual Power Supply rear connectionsNote: more power supply installation details arecovered in section 2.3.1®S peaker Panelprogramm ingportRX2RX1OFFSP EAK ERSELE CT SWI TCHNotUsed with800 MHzSeries Imodel15A+-OutputSense+-RemoteFail Alarm13.8VMax.
120 20170-302 ParagonPD Technical Manual133.1.2 Radio Assembly, rear panel3.1.2.1 Backplane PCBReferring to Figure 3, two main backplanes areused. Their main components are:• RJ11 connector – Mirrors the one on thefront of the Speaker panel (series con-nected to both backplanes). Used forprogramming the Radio Assembly when-ever the speaker panel has been removed.• DB-25M plug at PL1 (one side of the“Y” cable on each PCB) – used to supplythe receive signal to the BDLCPD’s single“EXT.RADIO/TEST” DB-25F plug.• Two channel-select DIP switches (SW1and SW2)This feature is exclusive to the Series II model.• Cooling fan driver – CN2 located onbackplane connects to the horizontally-mounted fan on top of the Radio assem-bly and activated by BDLC’s PTT signal.• Coaxial relay driver – not used.3.2 BDLCPDThe rack-mounted BDLCPD is housed in a steelcase. It has no user serviceable parts. Unit’s con-figuration is stored in flash memory (EEPROM).3.2.1 BDLCPD Front panelReferring to Figure 2, the front panel of theBDLCPD has two cutouts across its length.A- The left cutout groups the unit’s type labeland ten LED indicators:• The S3 label designates the BDLCPD as a“three Serial-port” model(Ports 4 and 5 are reserved for future use)• The RF group of 3 LEDs• The RS-232 group of 5 LEDs• A single CK LED• The ALARMS group of 4 LEDsB- The right cutout groups two tactile (mem-brane) switches (PF1 and RESET).3.2.1.1 Front SwitchesReferring to Figure 11, the BDLCPD uses twomembrane-type switches labeled:• RESET• PF 1These switches indicate contact by emitting ashort BEEP tone when pressed.Figure 11 - BDLCPD membrane switches3.2.1.1.1 ResetPressing Reset produces the same result as pow-ering OFF and ON again. It restarts the micro-processor, the peripherals and invokes the on-board diagnostics. BDLCPD’s radio modules’ in-ternal flash-memories are read and their valuesare loaded in system SRAM CPU flash-memory.Normally, pressing Reset results in one shortBEEP tone followed by all LEDs coming ON forabout four seconds. Then, the LEDs flash in a“ripple” pattern for close to two seconds indi-cating diagnostics are in progress. At the end ofthis period, all LEDs should be OFF except CKthat should flash about six to eight times per sec-ond.Expect an additional two seconds delay for CK tostart flashing and the UF indicator to come ON ifthe radio assembly is not connected or not pow-ered (see section 3.2.1.5.4 for Alarm details).3.2.1.1.2 PF 1PF 1 is a multi-function switch:• It clears LED error indications• It initiates test transmissions• It sets the function of the RS-232 LEDsPF1 RESET
120 20170-302 ParagonPD Technical Manual143.2.1.2 Clearing ErrorsMajor and minor error LED indications remain liton the front panel until:• The unit is RESET• The unit is powered OFF and ON again• PF 1 is pressedThe PF 1 switch can be pressed at any time toclear an error display without affecting normaloperations.3.2.1.3 Test TransmissionsTo select a pattern and begin transmission, startby pressing and holding PF1. It beeps once, allfive RS232 LEDs light; listen for a second beepfollowed by a third beep. After two seconds, theunit beeps and goes in “TX Select” mode withonly the three rightmost RS-232 LEDs now usedas selection indicators. Only release PF1 after thethird beep.Following release:• Start of selection must be made within twoseconds. If not, the unit will default to patternone and start test transmitting.• PF1 may be pressed more than once. Thenumber of times it is pressed determines thetype of pattern that will be transmitted ac-cording to Table 3.• Each pressing of PF1 extends the two-secondtimer.• The three rightmost RS-232 LEDs displayare used to indicate TX mode selection asshown in Table 2.Table 2 - TX mode selection LEDs indicationsBinary TX mode LED indicationsTX patternselected FT LED RD LED TD LED1OffOffOn2 Off On Off3 Off On On4OnOffOff5OnOffOn6OnOnOff7OnOnOnOnce the type of transmission is selected, stoppressing PF1, allow the two-seconds timer to rundown. Automatically, the BDLCPD turns itstransmitter ON, sends the selected “test pattern”for 55 seconds and turns its transmitter OFF. TheTX LED in the RF group of indicators lights inred while test transmitting. Pressing PF1 whilethe 55 seconds test is in progress stops the test.At the end of test transmission, BDLCPD opera-tion returns to normal and the RX LED lights ingreen (monitoring normal transmitter activity).Table 3 - Test TransmissionsDGMSK ParagonPD# timesPF1 ispressed 8000 b/s 9600 b/s 19200 b/s1 2000 Hz Dotting2400 Hz Dotting4800 Hz Dotting24000 Hz 4800 Hz 9600 Hz3100 Hz Square wave4 Random data Random data Random data5 Unmod Unmod Unmod61000 Hz sinebeacon mode 1000 Hz sinebeacon mode 1000 Hz sinebeacon mode71000 Hz sine waveAdjustment tonexRC4FSK ParagonPD# timesPF1 ispressed 32000b/s 25600b/s 19200b/s 16000b/s 14400b/s14000 HzDotting* 3200 HzDotting* 2400 HzDotting* 2000 HzDotting* 1800 HzDotting*2Do notuse Do notuse Do notuse Do notuse Do notuse3100 HzSquarewave100 HzSquarewave100 HzSquarewave100 HzSquarewave100 HzSquarewave4Randomdata Randomdata Randomdata Randomdata Randomdata5 Unmod Unmod Unmod Unmod Unmod61000 Hzsinebeaconmode1000 Hzsinebeaconmode1000 Hzsinebeaconmode1000 Hzsinebeaconmode1000 Hzsinebeaconmode71000 Hzsinewave Adj. tone1000 Hzsinewave Adj. tone1000 HzsinewaveAdj, tone1000 HzsinewaveAdj, tone1000 HzsinewaveAdj, tone* Dotting with reduced amplitudeNotes:- For DGMSK models, a dotting pattern consists of analternating series of bits.- For the xRC4FSK models, a dotting pattern consists ofan alternating series of bits where only the lowest-levelsymbol’s modulation is used.- The square wave is used to check transmitter low fre-quency balance..- Pattern 6 produces a transmission of approximately 55seconds followed by about 55 seconds of silence.Initial transmission in a sequence may be shorter than55 seconds.

120 20170-302 ParagonPD Technical Manual153.2.1.4 RS-232 LED Function SelectionThe PF 1 button is used to select the RS-232 dis-play 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-232numbered LEDs (see Figure 13) willlight. If one LED lights, it denotes theport to which the subsequent display ap-plies. If all numbered LEDs light, it de-notes that the normal 3-port display modeis active.The selected display remains active untilmanually changed or until RESET ispressed or until power up.Table 4 - RS-232 LED Function Selection SequenceRS-232 LED Function Selection SequenceALL1234 (reserved)5 (reserved)TX LED in RF group lights with anyand all transmissionALL1234 (reserved)5 (reserved)TX LED in RF group only lights withan ACK or DATA transmission• If, during the 2 seconds period that CK is notflashing, PF 1 is pressed a second time, theLED functions will advance one step fromtop to bottom through the available options inthe order shown in Table 4.• PF 1 may be pressed repeatedly during the 2second period (extended with each press) toadvance to the desired numbered LED func-tion option.Once the desired RS-232 LED function is se-lected, stop pressing PF1, allow the two-secondstimer to run down. The BDLCPD returns to nor-mal operation using the newly selected display.3.2.1.5 LEDs and IndicationsLEDs are used to indicate the operation status ofthe BDLCPD. Although capable of displayingthree colors, only the green and red colors areused for the BDLCPD. They are grouped by theirfunction:• RF Group, displays radio channel status ingreen• RS-232 Group, displays serial port status ingreen except the TX LED that also uses red• ALARM Group, displays fault status in red3.2.1.5.1 Radio Network IndicatorsThe Radio Network LEDs are useful when trou-bleshooting as an indication of network activity.It can help isolate transmission problems.Figure 12 - RF indicatorsCS Carrier Sense - Steady light indicates that anincoming radio data signal is being detected bythe DSP modem. CS signal is not user-adjustable.RX Receive Data – Flashing light indicates unit isinternally receiving data from the radio network.TX Transmitter ON – blinks green indicates(depending on display mode selected):• That a data packet or ACK (packet acknowl-edgment) is being transmitted.• That an idle packet, data packet or ACK isbeing sent. Test transmission display is donein red.CS RX TXRF
120 20170-302 ParagonPD Technical Manual163.2.1.5.2 RS-232 Port IndicatorsThe RS-232 LEDs normally indicate port activityon the port selected. See section 3.2.1.4 above forinstructions for selecting display mode.Figure 13 - RS-232 Port LED indicatorsCM Command Mode - LED lights and re-mains lit while the selected port is ac-cessing the Command Processor. It lightsON and OFF while being configured.FR Flow Control on Receive - the BDLCPDhas received a flow control signal fromthe device connected to it. When it lights,BDLCPD has stopped sending data to theDTE. When LED goes out, the port ter-minal is again ready to receive data.FT Flow Control on Transmit - the BDLCPDhas sent a flow control signal to the DTEasking it to stop sending data. The LEDremains lit as long as the terminal is be-ing held off.RD Receive Data - when lit, it shows that theReceive Data pin 3 on the RS-232 inter-face connector is active. Since allBDLCPD are configured as DCE, it meansthat the DTE is receiving data from theBDLCPD.TD Transmit Data - shows the status ofTransmit Data pin 2 of the RS-232 inter-face. When lit, the DTE is sending datato the BDLCPD.3.2.1.5.3 Check and Power LEDsCK Check:Normally flashing rapidly (about 6 cps),indicates microprocessors are workingcorrectly and power is applied.Not flashing indicates unit is notfunctioning.Blinking slowly (1 cps), indicates the pa-rameters contents of the flash memory havebeen corrupted. The unit automatically loadsits set of factory default parameters andstarts beeping at 20 seconds intervals.May also indicate DSP-modem re-initialization has occurred3.2.1.5.4 Alarm IndicatorsAll alarm conditions will cause the BDLCPD tolight one or more of the LED indicators. LEDsremain ON when lit until cleared by eitherpressing PF 1 (without affecting operation of theunit) or RESET (cycling unit OFF and ON).Figure 14 - ALARMS LED indicatorsLM Local Minor Alarm - when lit, indicatesthe presence of any of the following mi-nor faults:- Parity, framing or overrun error at anyRS-232 port.- Out of buffers. No memory available toaccept data from a local terminal device.Usually denotes a flow control problem.- Flash memory error. At power-up orreset, the unit detected a change in non-volatile memory.RM Remote Minor Alarm - when lit, indi-cates any of the Local Minor Alarmlisted above have taken place at the re-mote end of the link (i.e. the mobile thelocal base station is currently communi-cating with). It will also light when aprotocol error has been detected on thenetwork.In a network using the “Host Link Ac-tive” (MSC) feature, the RM LED,flashing in-sync with the CK LED, indi-cates that the link is down.LF Link Failure - when lit, indicates that thebase station fails to receive an ACK for a321RS-232CM FR FT RD TDALARMSLM RM LF UF
120 20170-302 ParagonPD Technical Manual17packet sent and for all subsequent retries.Some data has possibly been lost. LF isnot functional if all active ports are set toNAR mode.Link fails are inevitable during normaloperation (mobiles temporarily out ofrange, in a tunnel, parked in a dead spot,etc.). A lit LF LED is not normally causefor concern.UF Unit Failure - when lit, the unit requiresattention: - The BDLCPD is not operable;It may indicate detection of a systemsoftware error trap.- The BDLCPD is operable;Indicates that on power-up, invalid datawas detected in the serial EEPROM chip(located in the radio modules). It mayalso indicate that connection to the radiomodules is incorrect or that radio poweris not applied.The LM, RM and UF alarms also sound a beepwhen a fault occurs. The LF alarm is silent.3.2.2 BDLCPD Rear panelReferring to Figure 4, the rear panel of theBDLCPD has the following set of chassis con-nectors:• One DB-25F connector– DEV1 - Connects to user’s application.a) DMP 19200 or 38400 baud for single-site installationsb) MSCP 19200 or 38400 baud for multi-site installations• Four DE-9F connectors:– DEV2 - usually connected to Dataradio’sWinRIS program (Dedicated or DMP at19200 baud).– DEV3 - Dedicated (up-to 9600 baud)– DEV4 and DEV5 - not used• One DA-15M connector:– DEV6 Digital I/O - not used• One DB-25M connector:– EXT RADIO/TEST - connects to the Ra-dio assembly through the radio interfacecable (see Figure 15)3.2.2.1 RS-232 Signal LevelsIn the description of data signals in Table 7, thefollowing conventions are used:Table 5 - RS-232 Signal levelsTerm Alternates Signal levelON Asserted, spacing +3 to +15 VOFF Dropped, marking -3 to -15 V3.2.2.2 Pin FunctionsTable 6 - DTE Port 9-pin funtionsDE-9 Fpin # Function (RS-232 signal levels)1 DCD – from ParagonPD, normally asserted2 RXD – data from ParagonPD3 TXD – data to ParagonPD4 DTR – to ParagonPD, handshaking5 Ground6 DSR – from ParagonPD, tied to VCC throughcurrent limiting resistor7 RTS - to ParagonPD, handshaking8 CTS – from ParagonPD, handshaking9 ReservedTable 7 - DTE Port 25-pin functionsDB-25Fpin # Function (RS-232 signal levels)1 and 7 Ground2TXD – data to BDLCPD3RXD – data from BDLCPD4RTS – to BDLCPD, must be asserted5CTS – from BDLCPD, handshaking6DSR – from BDLCPD, always +8V8DCD – from BDLCPD, always asserted9RI - from BDLCPD, always –8V20 DTR – to BDLCPD, handshakingWe recommend the use of shielded 9-wire or25-wire cables with all pins connected.Dataradio recommends the use of secure (i.e.password protected and/or dial-back) modems inany installation where dialup access is provided..

120 20170-302 ParagonPD Technical Manual275.1.3 Channel Selection via DIPSwitchesThe backplane-mounted DIP switch settingsoverride the default channel programmed byPGM800Win.To set a default channel via the software, allDIP switches must be set to “OFF” (i.e.00000000).When a switch is “Off”, its binary count is ac-tive; when a switch is “ON” its binary count isinactive. The various DIP switch combinationsof ON or OFF make up a binary total, whichidentifies the channel number.To select a channel, set the appropriate DIPswitch or switches to “OFF” to make the binarycount total the channel number you want. Set allother switches to “ON”.It is recommended to set both SW1 (RX) andSW2 (TX) to the same settings on both backplane boards.Example: To select channel 5, set the DIPswitches as shown below:Figure 21 - Backplane DIP switches example - Channel 5 selectedBinary Value1248163264Always ON except whendefault channel is requiredCHANNEL SWITCH TXCHANNEL SWITCH RX12345678OFF12345678OFF

120 20170-302 ParagonPD Technical Manual363. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum supply cur-rent, 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 re-duced 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.- Do not re-install the Exciter module back in the ParagonPD rack frame.- Connect the Exciter module to the Power Amplifier using the 18" coax cable N-M to BNC-M(727-03353-101)- Connect the Power Amplifier output to the IFR T/R connector or to a stand-alone BIRD stylepower meter, terminated with a 150W dummy load.5.2.5.1 Power Output alignment (from TPL Communications)a) Key the transmitter using the Exciter Carrier button.b) Adjust VR 1 (LMS rear panel) and reduce power output to its nominal value (100W, max 125W)or lower as required. Warning:Do not drop the power to less than 65 Watts. Setting a lower value may create spuriousemissions that can create interference with adjacent channels.5.2.5.2 Forward Power Alarm Levela) Key the transmitter using the Exciter Carrier buttonb) Adjust T881's RV502 Exciter output power to drop the RF power amplifier output to 65 Watts.c) Adjust TPL's VR5 until the front panel LED begins to flash.d) Adjust T881's RV502 (Exciter) output level to the normal operating power level.5.2.5.3 Amplifier Activationa) Key the transmitter using the Exciter Carrier buttonb) Set T881's RV502 Exciter output power to a level 6 dB below the normal drive level. (e.g. divideby 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 buttonc) Adjust TPL's VR8 to a nominal 10 units at nominal input drive5.2.5.5 Forward Power meter calibrationa) 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 calibrationa) Connect an unterminated 3dB pad to the PA output (e.g. 3:1 VSWR).

120 20170-302 ParagonPD Technical Manual44Appendix 1 - ParagonPD Deviation adjust1. 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 serialnumber (e.g. abcd.bp2). “Save as” to another file name and keep it in case something goeswrong while changing a parameter.3. Locate the line labeled “Dev0 Par85=” and record the value beside the “=” sign. This is thecorresponding 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)] + 25. 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 thatyou 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) upor down, fine-tuning directly the Par85 (DSP deviation) parameter. Do steps 6 and 7again to confirm acceptance.This last step may have to be repeated once or twice while varying the entered valueup or down. If unable to obtain the correct level after editing up and/or down by nomore than 2, contact System Engineering.
