The DEVA FM Monitoring receivers supports a very wide range of GSM Modems. 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 pre-
configured 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. All the documents are available
