External GSM Modem Settings
To fulfill the Remote Monitoring Functions via GMS it is necessarily to connect an external
GSM modem to DB4402. To do this, connect the GSM Modem to the rear panel DB-15 male
connector through the cable provided together with GSM Modem. A GSM Antenna must be
supplied and connected to the connector of the GSM Modem.
IMPORTANT:
Position the GSM Antenna as far as possible from the DB4402’s FM Antenna.
WARNING:
Please check SIM Card PIN request to be disabled. Otherwise DB4402 can not
operate the modem.
The GSM Modem must be configured with the following settings:
Baud rate: equal to DB4402 setting (see “Main Settings Screen” on page 49 )
Data bits: 8
Stop bit: 1
Parity: None
Hardware Flow Control: None
NOTE:
The GSM Modems provided by DEVA Broadcast Ltd. are pre-configured. In case of
using different modems, please comply with the settings above.
To ensure proper installation of the GSM Modem, please observe the following sequence:
1. Install and connect the GSM Antenna according to the above recommendations.
2. Insert the SIM card into the holder. Card must be with deactivated PIN request.
3. Connect the GSM Modem and DB4402 with the communication cable.
4. Power-up the GSM Modem.
5. Power-up DB4402.
If the installation is proper, the GSM Modem will immediately startup. This will be noticed by
the fast blinking of the ‘GSM’ Led on the DB4402’s front panel. The status of the GSM Modem
will also be exposed on “Status Screen” . Few seconds are usually necessary for the GSM Modem
to initialize and to register into the GSM Network. When the GSM Modem is Ready the ‘GSM’
Led will start blinking slowly. The GSM Opeartor’s Logo and the Field Strength will be also
shown on the “Status Screen” .
It is important to notice the call duration, which is 1 minute, otherwise the GSM connection
may turn overused. ‘Call Duration’ defines the maximum outgoing call duration, which will be
hanged-up by DB4402 when it reaches the defined value (1 minute).
Only authorized GSM numbers can request remote notifications and remote listening. To
register up to four GSM numbers use Main Settings Screen.
It is important to enter the GSM numbers properly, using the correct prefix for the country. For
example: +359898123456
NOTE:
The GSM Modem may be connected to DB4402 without shutting down the device - so
called ‘Hot Plug’. When disconnected or powered down, the GSM Modem can be reconnected after
the ‘GSM’ Led stops blinking (about 5 seconds). To prevent possible problems, we recommend,
when possible, not to use ‘Hot Plug’.
