Series I model’s programming isdone externally via EPROMs.• DB-25M plug at PL1 (one side of the “Y”cable on each PCB) – used to supply the re-ceive signal to the BDLCPD’s single“EXT.RADIO/TEST” DB-25F plug.• Two channel-select DIP switches (SW1 andSW2)This feature is exclusive to the Series IImodel.• Cooling fan driver – CN2 located on back-plane connects to the horizontally-mountedfan on top of the Radio assembly and acti-vated 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’sconfiguration 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’internal flash-memories are read and their val-ues are loaded in system SRAM CPU flash-memory.Normally, pressing Reset results in one shortBEEP tone followed by all LEDs coming ONfor about four seconds. Then, the LEDs flash ina “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 persecond.Expect an additional two seconds delay for CKto start flashing and the UF indicator to comeON if the radio assembly is not connected or notpowered (see section 3.2.1.2.4 for Alarm de-tails).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

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 afterthe third beep.Following release:• Start of selection must be made within twoseconds. If not, the unit will default to pat-tern one 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-second timer.• 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 On4OnOffOff5OnOffOn6 OnOnOff7OnOnOnOnce the type of transmission is selected, stoppressing PF1, allow the two-seconds timer torun down. Automatically, the BDLCPD turns itstransmitter ON, sends the selected “test pattern”for 55 seconds and turns its transmitter OFF.The TX LED in the RF group of indicatorslights in red while test transmitting. PressingPF1 while the 55 seconds test is in progressstops 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 TransmissionsDGFSK ParagonPD# timesPF1 ispressed 9600 b/s 16000 b/s 19200 b/s12400 HzDotting 4000 HzDotting 4800 HzDotting2 4800 Hz 8000 Hz 9600 Hz3 100 Hz Square wave4 Random data5 Unmod61000 Hz sinebeacon mode71000 Hz sine waveAdjustment toneSRRC4FSK ParagonPD# timesPF1 ispressed 14400b/s 16000b/s 19200b/s 25600b/s11800 HzDotting* 2000 HzDotting* 2400 HzDotting* 3200 HzDotting*2 Do not use3 100 Hz Square wave4 Random data5 Unmod61000 Hz sinebeacon mode71000 Hz sine waveAdjustment tone* Dotting with reduced amplitudeNotes:- For DGFSK models, a dotting pattern consists of analternating series of bits.For the SRRC4FSK models, only the lowest-levelsymbol’s modulation is used.- The square wave is used to check transmitter lowfrequency balance.- The 1000 Hz sine can be used for transmitter distor-tion measurements.- Pattern 6 produces a transmission of approximately55 seconds followed by about 55 seconds of silence.

If one LED lights, it denotesthe port to which the subsequent displayapplies. If all numbered LEDs light, itdenotes that the normal 3-port displaymode is active.The selected display remains active un-til manually 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 isnot flashing, PF 1 is pressed a second time,the LED functions will advance one stepfrom top to bottom through the availableoptions in the order shown in Table 4.• PF 1 may be pressed repeatedly during the 2second period (extended with each press) toadvance to the desired numbered LEDfunction 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.3.2.1.2 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 red3.2.1.2.1 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 indicatesthat an incoming radio data signal isbeing detected by the DSP modem. CSsignal is not user-adjustable.RX Receive Data – Flashing light indicatesunit is internally receiving data from theradio network.TX Transmitter ON – blinks green indicates(depending on display mode selected):• That a data packet or ACK (packetacknowledgment) is being trans-mitted.• That an idle packet, data packet orACK is being sent. Test transmis-sion display is done in red.3.2.1.2.2 RS-232 Port IndicatorsThe RS-232 LEDs normally indicate port activ-ity on the port selected. See section 3.2.1.1.2.3above for instructions for selecting displaymode.CS RX TXRF

Itlights ON and OFF while being config-ured.FR Flow Control on Receive - the BDLCPDhas received a flow control signal fromthe device connected to it. When itlights, BDLCPD has stopped sendingdata to the DTE. When LED goes out,the port terminal is again ready to re-ceive data.FT Flow Control on Transmit - the BDLCPDhas sent a flow control signal to theDTE asking it to stop sending data. TheLED remains lit as long as the terminalis being held off.RD Receive Data - when lit, it shows thatthe Receive Data pin 3 on the RS-232interface connector is active. Since allBDLCPD are configured as DCE, itmeans that the DTE is receiving datafrom the BDLCPD.TD Transmit Data - shows the status ofTransmit Data pin 2 of the RS-232 in-terface. When lit, the DTE is sendingdata to the BDLCPD.3.2.1.2.3 Check and PowerCK Check:Normally flashing rapidly (about 6 cps),indicates microprocessors are workingcorrectly and power is applied.Not flashing indicates unit is not func-tioning.Blinking slowly (1 cps), indicates theparameters contents of the flash memoryhave been corrupted. The unit automati-cally loads its set of factory default pa-rameters and starts beeping at 20 sec-onds intervals.May also indicate DSP-modem re-initialization has occurred3.2.1.2.4 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 availableto accept data from a local terminal de-vice. Usually denotes a flow controlproblem.- 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.ALARMSLM RM LF UF321RS-232C M FR FT RD TD

Adjust CV1 for maximum output.6. Adjust CV8 for maximum output.7. Adjust CV32 for maximum output.8. Adjust CV51 and CV57 for maximum output.9. Adjust CV34 and CV35 for maximum output.10. Recheck all settings. The power output should exceed 110W.11. 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 to reduce the power output to the required level (normally100W).6.4.4.5 Tait T859 Tuning for Best Efficiency1. Insert a Shunt current device (HP 34330A Shunt 30A ) between the power supply redwire 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.3. Retune CV32, CV51 and CV57 towards maximum capacitance to obtain minimum sup-ply 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 currentis reduced too far, maximum power output will drop and 2f rejection may degrade.

120 20170-201 ParagonPD Technical Manual57Appendix 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.
