BasicFunctions
·The2N®MobileAudio Gateway
(hereinafterMAG)isdesignedto
automaticallyansweracallfromthe
GSMmobilenetworkandtransferthe
caller’svoicetoaudiooutput.Itis
designed to be connected to theinputof
aPAexchangeorsimilardevice
intended forvoice reproduction.
·Thedeviceisequippedwithaswitching

exchange during an ongoing call.
2N® MobileAudioGatewayInstallationandConnection
·Properlocation
Install MAG withrespectto agoodmobile
networksignalstrength.
PlaceMAG outofrangeofsensitive
devicesandhuman bodiesfor
electromagneticinterferencereasons.
MAG isdesignedfor indoor use.Donot
placeit nearheatsourcesandondirect
solarradiation.Itmaynot beexposedto
rain,flowingwaterandmoisture,
aggressivegas,solventsetc.
·ExternalAntennaConnection
Screwthe antenna cord into the SMA
antenna connector.Tightenthe
antenna connectorgently withyour
hand,neveruse awrench!
·SIMcardInstallation
Slot forSIMcardisplacedonthe
connectorpanel.MakesureyourSIM
cardisnotPINprotected.Insertthe
SIMcardto theslot accordingto the
picture.IfyouwishtousePIN
protection,enterthePINcodeinto
MAG beforetheSIMisinserted.Use
the configurationtool.
·ConnectionofaudioinputtoMAG

Use ofthedevice
·Whenthereisan incomingcall, MAG
automaticallypicksupthecalland
connectstheaudiooutputwiththe
incoming GSMvoice channel.
·Italsoclosesrelaycontactsconnectedto
therelayconnector.Thisenables
activationoftheconnectedaudio device
and reproductionof the caller’svoice.
·Thestateoftheongoingcall issignalled
by the LEDAudio connection.
·Attheendofthecall by thecaller,the
MAG goesinto standby mode.
ConfigurationviaUSB
·Thedeviceisfullyfunctionalinthe
default configuration.Ifyoudon’tneeda
specialsetting,it isnot necessaryto
configure the device.
·Forconfigurationby PC, youmustinstall
thePCManagerUNIprogram.Connect
the MAG byUSB cable to the PC.
·Afterconnection,avirtualseriesportis
created(USB serialport, FTDI)through
whichthePCManagerconnectsto the
gateway.
·WhensettingupPCManager,it is
necessaryto selectthenumberofthe
virtualseriesport.
·Using PCManager,youcan:
-EnterthePINoftheSIMcardused
(protection)
-Permit callsfromselectednumbersonly
(GSMrouting table)
-Configure outputvolume (telephone line)
-ConfigureparametersofGSMconnection,
especially roaming (GSM&SIM)
-Upgradefirmware-onlywithspecialFW
