120 20170-200 ParagonPD Technical Manual72.3.1 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 powersupply units joined in a single chassis:• A T807 using convection cooling is rated upto 15A. It supplies all the radio modulesother than the Power Amplifier.• A T808 using convection and fan cooling israted up to 25A. It supplies only the PowerAmplifier module.Normally used at room ambient temperatures,they can operate within specifications over arange of –10 to +60 °C.Note: Internal over-temperature protectionshuts down the main transformer above105 degrees 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 separatesecure 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 courtesysmall-parts kit or with one end fastened to theequipment.A- For each of the power supply modules:1. Fit one end of the grounding lead’spush-on connector onto the ground-ing tab.B- For the Radio Assembly chassis:1. Install the grounding lead’s lug overthe binding post and firmly hand-tighten the binding-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 se-cure electrical and mechanical connec-tion is achieved.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 powersupply case and rack frame may resultin harmful voltage potentials and/ormiscellaneous power supply switchingnoise 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 3.2.1.2The 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) 30A
120 20170-200 ParagonPD Technical Manual82.3.2 BDLCPD assembly PowerThe BDLCPD assembly uses a standard 120VAC power cord. Plug this cord to the rearpower outlet shown in Figure 6.To check or install a fuse:1. Open the slide-out fuse drawer located be-low the power connector.2. Use a fine bladed screwdriver or a knifeblade and gently pry open.3. Hold the fuse support in one hand and withthe other, lift the center plastic retainer untilit releases the fuse sliding base.4. Replace or install a 250V, 2A fuse.5. To complete the procedure, push the slidingfuse base until it snaps under the retainer.6.

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’internal 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 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-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 LED1 Off Off On2 Off On Off3 Off On On4 On Off Off5 On Off On6 On On Off7OnOnOnOnce 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.The TX LED in the RF group of indicators lightsin red 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 TransmissionsParagonPD# timesPF1 ispressed 16000 b/s 25600 b/s1 2400 Hz Dotting* 3200 Hz Dotting*2 Do not use Do not use3 100 Hz Square wave 100 Hz Square wave4 Random data Random data5 Unmod Unmod61000 Hz sinebeacon mode 1000 Hz sinebeacon mode71000 Hz sine waveAdjustment tone 1000 Hz sine waveAdjustment tone* Dotting with reduced amplitudeNotes:- A dotting pattern consists of alternating sequence of1’s and 0’s- The square wave is used for balancing transmitterlow frequency response- The 1000 Hz sine can be used for transmitter distor-tion measurements.- Pattern 6 produces a transmission of 55 secondsfollowed by 55 seconds of silence. Initial transmis-sion in a sequence may be shorter than 55 seconds.TX LED stays steadily red for duration of the test.Press PF1 to terminate beacon mode.3.2.1.1.2.3 RS-232 LED FunctionSelectionThe PF 1 button is used to select the RS-232display 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 theRS-232 numbered LEDs (see Figure 13)will light. 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 until
120 20170-200 ParagonPD Technical Manual14manually 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 any andall 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 optionsin 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 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.3.2.1.2 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 is be-ing 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 transmitted.• 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.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.

120 20170-200 ParagonPD Technical Manual15FR Flow Control on Receive - the BDLCPDhas received a flow control signal fromthe device connected to it. When itlights, BDLCPD has stopped sending datato the DTE. When LED goes out, theport terminal is again ready to receivedata.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, itmeans that the DTE is receiving datafrom the BDLCPD.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.3.2.1.2.3 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 UF
120 20170-200 ParagonPD Technical Manual16LF Link Failure - when lit, indicates that thebase station fails to receive an ACK fora packet sent and for all subsequent re-tries. Some data has possibly been lost.LF is not functional if all active ports areset to NAR 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 normallycause for 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:• Four DE-9F connectors:– DEV2 - usually connected to Datara-dio’s RIS program (DMP/Setup 19200).Can also be used with special user’s ap-plication such as telephone modemNote: connection to a telephone re-quires the use of a DCE Crossover ca-ble.– DEV3 - Dedicated (9600)– DEV4 and DEV5 - not used• One DB-25F connector- DEV1 - Connects to user’s application.a) DMP 19200 for single-site installa-tionsb) MSCP 19200 for multi-site installa-tions• One DA-15M connector:- DEV6 Digital I/O - not used• One DB-25M connector:- EXT RADIO/TEST - connects to theRadio assembly (see Figure 15)3.2.2.1 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 or 25-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.

(mini-mum requirement to reach is 12 dB SINAD for –110 dBm)5) Perform the SINAD linearity tests described in the next paragraphs below. If it fails to pass therequirement, contact your Dataradio technical support.
120 20170-200 ParagonPD Technical Manual34WARNING: Do not attempt to re-tune the IF stages (i.e. L312 to L318).These adjustments do not need to be re-adjusted after frequency re-programming.Touching these coils will have a direct impact on the DSP modem coefficient settingsand may significantly reduce the radio performances over data.6.2.2.4 SINAD and Linearity Check1. Apply the following settings to the IFR:- Generator mode, Output T/R- IFR 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, except for “wide-band”.- Set deviation to ±3.0KHz for full channel or ±1.5KHz for half channel radios.2. Lower the RF level to get a 12dB SINAD reading. Level must be better than -110dBm (includingcable loss).3. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) above the main radio RXfrequency, record the SINAD reading. It should remain within 1.5dB from the on frequencySINAD reading.4. Offset the IFR TX frequency 2KHz (full channel) or 1kHz (half channel) below the main radio RXfrequency, record the SINAD reading. It should remain within 1.5dB from the on-frequencySINAD reading.Note: If one of the above requirements is not met, try to re-tune the front-end. If it is still “failed”, contact your Dataradio technical support.6.2.2.5 RSSI AdjustmentNote: This check is only recommended for ParagonPD model running DBA protocol 3.06.009 series orlater.1. Apply an on-channel signal from the RF generator at a level of -110dBm with deviation of ±3kHz(full channel) or ±1.5kHz (half channel) at 1kHz tone.2. Adjust RV301 (RSSI level) to give 2.0V RSSI output when measured with a multimeter at SK301pin 2 or on the relevant backplane board at SK1 pin 5 (see Figure 30 for test point location).3. Vary the RF level in 10dB steps and check that the RSSI output voltage changes at a rate of a10dB/V (±0.20VDC) over the range of –120dBm to –80dBm. If the requirement cannot bereached, contact your Dataradio technical support.

120 20170-200 ParagonPD Technical Manual446.3.3 Channel Selection via DIP SwitchesThe backplane-mounted DIP switch settings override the default channel programmed byPGM800Win.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 inac-tive.The various DIP switch combinations of ON or OFF make up a binary total, which identifies thechannel number. To select a channel, set the appropriate DIP switch or switches to “OFF” to makethe binary count total the channel number you want. Set all other switches to “ON”.It is recommended to set both SW1 (RX) and SW2 (TX) to the same settings.Example: To select channel 5, set the DIP switches as shown in below:Figure 27 - Backplane DIP switches example - Channel 5 selectedBinary Value1248163264Always ON except whendefault channel is requiredCHANNEL SWITCH TXCHANNEL SWITCH RX12345678OFF12345678OFF

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 supplycurrent, 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 cur-rent is reduced too far, maximum power output will drop and 2f rejection may degrade.

Using Windows Notepad, Edit the .bp2 file named with the corresponding BDLCPD serialnumber (e.g. abcd.bp1). “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 RIS again and do a “Put From”. From the opened window, select the file that you justmade the change to and then press “OK”7. Again, check deviation level while pressing TX ON (Modulated). If fine-tuning of Par90 valueis still required, Edit the file again and re-do step 5 by changing directly the Par85 value by 1or 2 up or down.8. Re-check deviation level. If the level is now correct, press Stationreset to make the changepermanent.
