2GETTINGSTARTED



PluganEthernetcableintoanEthernetswitch,routeroradaptorcapableofprovidingPower‐over‐

Ethernet(PoE)toIEEE802.3af,andconnecttheotherendtothe625instrument.



TheEthernetinterfaceisprovidedbyaLantronixxPICO110device.Undernocircumstancesshouldthis

devicebere‐configured.



IntheeventthatthelabelshowingtheinstrumentMACaddressisaccidentallyremovedfromthe

instrument,itispossibletorunautilitythatwillreadtheinstrument’sMACaddress.This‘DeviceInstaller’

programcanbedownloadedfrom:

https://www.lantronix.com/products/deviceinstaller/



Whensuppliedfromthefactory,thedeviceisconfiguredtoconnectautomaticallytoanetworkusingthe

DHCPprotocolwithdynamicIPaddress.



2.1ETHERNETCONTROL



ThefollowingareexamplesofestablishingcommunicationwiththeattenuatorusingTelnetorRAW:



TELNET

TocontroltheinstrumentusingaTelnetconnection,withaTelnetclient(controlprogram)suchasPuTTY:

Entertheinstrument’sIPaddress,e.g.128.0.0.59,andtheportnumberof10001;

Totesttheconnectiontype‘identity?’andpressreturn.Theinstrumentwillreturnitsidentity

string,e.g.FLANNMICROWAVE,625PRVA,123456,V1.1.



TheWindowsOperatingSystemincludesaTelnetfunctionwhichcanbeusedfromaCommandLine

window.ThisfeaturemayhavetobeturnedoninWindowsfirst.



Someclientsdonotechothetypedinformation,oratleastnotwithoutchangingdefaultsettingsto

allowthis.The\nterminatorisnotrequiredinTelnet.



RAW

TocontroltheinstrumentusingaRAWconnection,withasuitableclientprogramsuchasPuTTY:

EntertheIPaddress,eg128.0.0.59anduseport10001;

Youarenowconnectedtotheinstrument;

Totesttheconnection,enter‘identity?\n’andpressreturn.Theinstrumentwillreturnitsidentity

string,egFLANNMICROWAVE,625PRVA,123456,V1.1.



Notethatthe\nterminatorisrequiredforRAWcommandsunlessusingaprogram,suchasPuTTY,that

terminateseverycommandstring.

3ENVIRONMENTALCONSIDERATIONS



TheModel625SystemAttenuatorisdesignedtooperatein‘non‐hazardous’indoorindustrialor

laboratoryareas,orinaprotectedoutdoorenvironment.



TheoperatingenvironmentmustconformtotheconditionsshowninTable1.Operationoutsidethese

rangescannotbeguaranteedandmayposedangerstotheoperatororcausemechanicalorelectrical

failureoftheequipment.Theinstrumentcanbecomewarmduringoperation,anditisimportantto

maintainadequateventilationatalltimes.

4SYSTEMFUNCTIONSANDFEATURES

4.1POWER‐UPPROCEDURE

WhentheinstrumentisconnectedtoaPoE‐compatiblenetwork,itresetstothe60dBreferenceposition.

Thisactionmaybedisabledifrequired,buttheinstrumentmustberesetassoonaspossibletoestablish

thecorrectreferencealignment.Refertothe‘PWR_ON_RST’and‘RESET_INST’commandsinsection5.2.

Theinstrumentissuppliedwith‘PWR_ON_RST’settoON.



Theinstrumentcanbeprogrammedtoreturntothelastsettingpriortopowerbeingremoved.Referto

the‘HOLD_SET’command.



4.2SETTINGATTENUATION



Theinstrumentcanbesettoattenuationvaluesintherange0.0dBto60.0dBusingtheVALUE_SET

command.Thesmallestincrementalvaluedependsontheabsoluteattenuation:0.01dB(upto20dB

attenuation),0.02dB(20to30dBattenuation),0.05dB(30to50dBattenuation)and0.1dB(50to60dB

attenuation).Itispossibletopositiontheinstrumentusingmotorstepsintherange0to9799,giving

increasedresolutionatlowerattenuationsettings.Refertothe‘STEPS_SET’commandinsection5.2,and

Table2below.Notethatthestepsarefrom0dB,andthecharacteristicisnon‐linear.

Whenthehighattenuationsettingisactive,thisenablesacoarseattenuationsettingofupto90dB.

Refertothe‘HIGH_ATTEN’command.Theattenuationaccuracybeyond60dBisnotguaranteed.The

4.3INSTRUMENTERRORS



InstrumenterrorscanbeidentifiedbyinterrogatingtheStatusByte(seeinformationforthe‘INST_STAT?’

insection5.2,andrefertoTable3).

4.4FIRMWAREUPGRADES

5ETHERNETCOMMANDSTRUCTURE



Thissectiondetailsthecommandsavailableandthevalidoperandsthatmaybeusedwiththem.



5.1NOTATION



Uppercaseboldcharactersrepresentthe(programcode)commands,whichmustappearexactlyaslisted.

Programcodecommandsarenotcasesensitive,i.e.upperandlowercasecharactersareaccepted.The

inputbufferis50bytesmaximum.



Charactersenclosedinthe{}bracketsarequalifiersattachedtothebasiccommand.Aspacemaybe

insertedbetweenitandbasiccommand,e.g.{ON|OFF}showsthateitherONorOFFcanbeattachedto

therootmnemonic.



Forexample,the‘PWR_ON_RST’commandhasthreepossibleapplications:



1.PWR_ON_RSTON‐ SwitchonthePower‐onReset

2.PWR_ON_RSTOFF ‐ SwitchoffthePower‐onReset

3.PWR_ON_RST?‐QuerythepresentstateofthePower‐onReset



Eachprogramcommandmustbeterminatedwith\n(Hex0x0a),unlessusingTelnet

Forexample:‘VALUE_SET45.3\n’



Forinstrumentstatecommands(identifiedwith‘Query:Valid’),appendthequestionmarkcharacter(?)

tothebasiccommandwithoutqualifierstointerrogatethestateofthefunctions.Theinstrument

respondstothequeryasdescribedforeachcommand.ForanON/OFFcommand,theresponseisa‘1’or

a‘0’toindicateOnorOff.Forasettablefunction,suchasVALUE_SETvalue,usingVALUE_SET?returns

thefunction’scurrentvalue.



5.2COMMANDSET



VALUE_SET[value]

Setstheattenuationofthemicrowaveinstrument,indB,tovalue

Query: Valid,returnssetting

Value 0to60.0(dB)



STEPS_SET[value]

Setstheattenuationofthemicrowaveinstrument,insteps,tovalue

Query:  Valid,returnsnumberofstepsfromreference

Value  0to9799



INCR_SETvalue

Setsthestoredincrementtovalue

Query:  Valid,returnsstoredincrement

Value 0to60.0(dB)



INCREMENT

Increasethemicrowaveinstrumentsettingbythestoredincrement(dBonly)

Query: Invalid



DECREMENT

Decreasemicrowaveinstrumentsettingbythestoredincrement(dBonly)
