External connections
GSM antenna connector
An SMA antenna input is used to connect an external GSM antenna. To establish a
connection with a GSM network, an external antenna must be used. Type of antenna
depends on the GSM coverage. In good circumstances (level of received signal is high)
use the antenna supplied in the package. If the range of GSM is low or none, an outdoor
or indoor (for instance in a place where GSM range is sufficient) antenna should be used.
Note: If there is no antenna connected to the SMA connector, connection with a GSM
network is impossible.

Checking the communication with the modem
Once the modem is connected you can check RS232 or USB communication between
the RB900-Pro and the PC using any Terminal program. Configuration of the DTE (port
COM) could be as follows:
• Bits per second: 115200 bps,
• Data bits: 8,
• Parity: None,
• Stop bits: 1,
• Flow control: hardware.
Using a communication software such as Hyperterminal, enter the AT and push 'enter'
button. The response of the terminal should be 'OK' displayed in the Hyperterminal
window.
If the connection with the modem cannot be established do the following:
• Check if modem is connected with PC via RS-232 or USB.
• Check the configuration of the COM port.
Examples of AT commands:
• ATE1 enables modem echo function,
• AT+CPIN? shows current status of SIM card
• AT+CPIN=xxxx to enter PIN, where 'xxxx' are digitals
• AT+CSQ to verify received signal strength
• ATD<phone_number>; to initiate a voice call
• ATH to hang up a voice call
For further information about AT commands and their usage, refer to [1].
Disabling and enabling echo function
If echo is not displayed when entering AT command, that means:
• The local echo function in software (such as Hyperterminal) is disabled
• The echo function of the modem is disabled
To enable echo function of the modem enter the ATE1 command.
In Machine to Machine communication it is recommended to disable echo function (type
ATE0) in order to avoid unnecessary CPU usage.
For further information about AT commands and their usage, refer to [1].
Page 19

Verifying the strength of received signal
RB900-Pro terminal can establish a connection with network if the received signal
strength is sufficiently strong. To verify the signal strength and bit error rate, do the
following:
using software such as Hyperterminal enter AT+CSQ. This command displays the
received signal strength indication <rssi> and channel bit error rate <ber>. The modem
answers as follows:
+CSQ: <rssi>,<ber>
OK
<parameter>
