Thisdocumentisintendedtoprovideguidancewhenaddingamodemfromthe
ZETA-NLPseriestoyoursystem.
TheZETA-NLPseriesofLTECatM1/NBIoT/GSMM2Mmodemsarean
advancedrangeofhighperformancemodemsdevelopedforeasyintegrationinto
existingsystemsandforembeddedapplicationdevelopment.
TheZETA-NLPmodemrangeisbasedontheTelitxE910GPRS/UMTS/LTE
moduleseriesandisdesignedtobeultralowpowerforuseinpowersensitive
applications.Themodemmanagesthemodulepowerupsequenceandcanbe
programmedtoperformadditionalcustomtasks.Inadditiontooffering2G/GSM
fallbackthemodemalsoprovidesaccesstothenewCatM1andNBIoTnetworks
forfullfuturecompatibility.
Thisdocumentdiscussesthemodemsstatesandmodesofoperationinaddition
totheelectricalcharacteristicsofthemodemsinterfaces.

AT Commands
TheZETA-NLPrangeofwirelessmodemshasacellularengineatitsheartwhichcan
becontrolledviatheserialinterfaceusingstandardATcommands.
TheATcommandisanATTENTIONcommandandisusedasaprextoother
parametersinaformattedstring.TheATcommandcombinedwithotherparameters
canbesenttothemodemwithyourpreferredterminalemulatorpackage(TMSTerm/
TeraTerm/HyperTerminal)andtypedinmanuallyasacommandlineinstruction.
ThewirelessmoduleiscompliantwiththefollowingATcommandformats:
1) HayesstandardATcommandset,inordertomaintainthecompatibilitywith
existingSWprograms.
2) 3GPP27.007specicATcommandandGPRSspeciccommands.
3) 3GPP27.005specicATcommandsforSMS(ShortMessageService)andCBS
(CellBroadcastService)
4) FAXClass1compatiblecommands
5) Proprietarycommandset,themodulefamilyalsosupportsaproprietarysetofAT
commandsforspecialpurposesoutsideofthestandardATspecication.

ZETA-NLP Series
LTE Cat M1/NB IoT/GSM Ultra Low Power Modem
TheZETA-NLPseriesmodemssupportastandardUSB2.0deviceinterface
compatiblewithUSB2.0specicationsandsupportingtheUSBlow-speed[1.5
Mb/s]andfull-Speed(12Mb/s)modes.TheUSBportcanbeusedtosendAT-
commands,reprogramthemodemsandviewdebugoutput.Themaximumbaudrate
availabletocommunicatewiththeZETA-NLPseriesmodemsisupto12Mbit/s.
DriversarerequiredtousetheUSBportandareavailableforseveraloperating
systemsincludingWindows/Linux.PleasecontactSirettaformoreinformation.
InhighspeedLTEmodesofoperation,thedownlinkdataspeedratescanbehigher
thanthemaximumRS232serialdatarate.Toachievethisnetworkdatarateusingthe
ZETA-NLP,integratorsneedtointerfacetheZETA-NLPtotheirapplicationsinfull-
speed(12Mb/s)mode.
Thedevicedrivercreatesupto6virtualCOMportsonthesystemforaccesstothe
module.4oftheseportscanbeconguredforuseasgeneralpurposeATcommand
communicationports.

TheZETA-NLPseriesmodemsdonotsupportautobauding.Integratorshavetoset
thecorrectspeedforserialcommunicationbeforedeviceinitialization.Iftheright
speedisset,thedevicerespondswithOKtoanyvalidATcommand.
Thedefaultbaudrateis115200.
Tochangethebaudrate:
»SendcommandAT+IPR=<rate><cr>
»Waitfor‘OK’response
