However, we suggest the usage of the following model - Sierra Wireless AirLink. This is the modem that is provided from DEVA Broadcast if the feature has been ordered along with the DEVA Unit. The GSM modem model is directly PIN to PIN compatible with the DEVA Unit GSM Modem's connector, and by simply using a direct cable, you will have not any troubles with the data communication and audio insertion. Before connecting the GSM Modem to the DEVA Unit, it is necessary to set up the parameters for normal operation. Please bear in mind that: · GSM modem does not have an automatic detection of the baud rate (AUTOBAUD function). The most important thing is to set up the GSM Modem communication settings. The Communication speed must be 9600 bps, Data Bits: 8; Parity: None; Stop Bits:1. · The SIM Card PIN code must be disabled in order to avoid a configuration problem of the modem. We suggest you to do this procedure using a GSM phone device of choice. This will save you a lot of time for reading the GSM Modem documentation. In case you decide to do that using the GSM Modem please refer to its User Manual for details. IMPORTANT: Once the GSM modem is properly installed, the DEVA Unit must be preconfigured to receive messages from up to 5 authorized numbers. This can be made via the WEB interface of the DEVA Unit. Upon successful installation, a notification message will appear on the unit's LCD/OLED screen (if such is available). Using this screen you can find the best place with good GSM Network coverage for the installation of the GSM modem. NOTE: For information, how the DEVA Unit can be accessed via the WEB Interface, please refer to the respective quick user guide for the device in question.

Then DEVA Unit will send you a message like the one depicted on the screen. · The ALARM Dispatch - This is a notification that the DEVA Unit will send to you in the cases when a parameters drops below or exceeds the pre-defined threshold. In case of ALARM, the unit will send SMS to all authorized GSM numbers. Bellow you will find examples how to use the DEVA Unit with GSM Modem features: REMOTE AUDIO LISTENING Type the following text and send it as SMS to the DEVA Unit's GSM number: Listen FFF.FF FFF.FF is the frequency to listen to. Upon receiving your `Listen' request via SMS, the DEVA Unit will call you back and when you take the call will hear the audio on the frequency FFF.FF IMPORTANT: Do not include leading zeroes such as "Listen 089.90" Fill with trailing zeroes up to two digits after decimal symbol. Decimal symbol must be `.' (not comma `,'). For example: "Listen 104.50" or "Listen 91.55". - 3 - 65 Aleksandar Stamboliyski Str., 8000 Bourgas, Bulgaria Tel: +359 56 820027, Fax: +359 56 836700 E-mail: office@devabroadcast.com ,Web: www.devabroadcast.com REMOTE STATUS REQUEST The DEVA Unit can send you a report with the values of the most important FM Parameters like RF level, MPX Level, Pilot Level, RDS Level, L&R Audio Level, Stereo/Mono Status and RDS PI Code at any time. Upon receiving your request via SMS, the unit's tuner will be adjusted on the requested frequency and will make measurement of all the parameters listed above. Once the procedure is completed, an SMS message will be generated and sent to the requestor's GSM. Command Example: Status FFF.FF FFF.FF is frequency to Tune. IMPORTANT: Do not include leading zeroes such as "Status 089.90" Fill with trailing zeroes up to two digits after decimal symbol. Decimal symbol must be `.' (not comma `,') For example: "Status 102.55" or "Status 88.80". The DEVA Units will shortly respond back with SMS with the following content (example): STATUS: 11.07.09 09:08:34 FREQ:102.50MHz RF Level: 55.1dBuV MPX Level: 74.1kHz Left: -11.7dB Right: -12.3dB Pilot: 7.5kHz Stereo RDS Level: 4.1kHz PI:824D - 4 - 65 Aleksandar Stamboliyski Str., 8000 Bourgas, Bulgaria Tel: +359 56 820027, Fax: +359 56 836700 E-mail: office@devabroadcast.com ,Web: www.devabroadcast.com INITIALIZATION PROCEDURE FOR SIERRA WIRELESS AIR- LINK FXT009 GSM MODEM in regards with the following DEVA Units: - DB44 Compact FM Radio Monitoring Receiver - DB45 DSP-Based FM Radio Receiver and Modulation Analyzer - DB4004 DSP-based FM Radio Monitoring Receiver - DB4005 SDR-Based FM Radio Modulation Analyzer and Monitoring Receiver - DB7000 FM Radio Re-Broadcast Receiver with Built-in IP Audio & MP3 Backup Players - DB7001 DSP-based FM Radio Re-Broadcast Receiver with TCP/IP Connectivity - DB7007 Advanced FM Radio Re-Broadcast Receiver with IP Audio & MP3 Backup Players - DB4402-V2 High-Performance Dual FM Monitoring Receiver & Radio Streamer 1. Setting up the modem Prior to connecting/using the GSM modem for the first time, kindly read the manufacturer's user manual. The document can be found on https://source.sierrawireless.com/resources/airlink/ hardware_reference_docs/airlink_fxt_series_user_guide/ The appropriate values should be assigned via the RS232 interface of the GSM modem. A custom made cable and a terminal program of any kind should be used. The cable specifications should be as follows: To PC DB 9 female pin GSM modem Note DB 15 male pin 1 > 1 Data Carrier Detect 2 > 6 com TX 3 > 2 com RX 4 > 8 DTR 5 > 9 GND 6 > 7 DSR 7 > 12 RTS 8 > 11 CTS 9 > 13 RI Next, the following settings should be applied to the terminal program: Speed 115200 bps. Flow control hardware (CTS/RTS) Parity none Data bits 8 Stop bits 1 To check the communication type the command "AT" in the terminal program and press Enter.
