Overview
The RB900-Pro terminal is the complete modem solution for wireless m2m applications.
Based on the high quality module, RB900-Pro offers high level GSM/UMTS/LTE Cat. 1,
GPIO and optional Dual SIM, MIMO, OneWire, GNSS receiver and internal battery
features in compact aluminum housing with all the standardized interfaces. Its small size
and wide supply voltage range, make it easy to integrate into all kinds of machines.
The RB900-Pro modem series, offering e-mail, TCP/UDP data transmission, SMS and
SMTP communication is a universal solution for all low-volume M2M and mobile data
applications including metering, traffic systems, transportation and logistics, security,
vending machines, and facility management.
The device can be controlled by standard AT commands or by customer's own
application, thus making it the smallest, most complete SMT platform for m2m solutions.
This document contains a full description of the RB900-Pro modem and gives
information about installation and use.

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.

D-Sub 15-pin connector
The RB900-Pro terminal is equipped with a D-Sub DE15F 15-pin connector to control
the RS232 interface, RS232 AUX/Debug/MCU/Modem (option) or RS485 Modem/MCU
(option).

is accessible externally. To insert a SIM card into the holder, press the yellow button,
eject the little drawer, place the SIM card inside and reinsert the drawer into the modem
(you will hear a “click”). To operate the module in a GSM network, it is necessary to insert
a SIM card obtained from the network operator.

Using the modem
Setting up the modem
To set the modem up, follow these steps:
•Eject SIM card holder using the yellow button and pull out the drawer.
•Insert your SIM card into the drawer.
•Verify if the SIM card fits in the drawer properly.
•Insert the drawer into the modem. Connect the antenna to the SMA connector
•Optionally, the modem can be connected using RS232 or USB interface
•Plug the power supply cable into the power supply input
•Now the modem is ready to work.
Installing USB drivers
Before you connect the device to the USB interface, you need to install the drivers.
They can be downloaded using the links below:
Windows: setup.exe
Linux: README

18
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 enteringAT 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].

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>
Description
<rssi>
0 through 31 - covers the range of -113 dbm (or less) to -51dbm (or greater)
<ber>
Channel bit error rate (in percent)
0–7 RXQUAL values in the GSM 05.08 table
99 Unknown or not detectable
For further information about AT commands and their usage, refer to [1].
PIN code status
To check the PIN code status enter AT+CPIN? Command.
The table below shows the relevant main responses of the modem:
Answer
Description
+CPIN: SIM PIN
PIN code has not been entered
+CPIN: READY
PIN code has been entered correctly
For further information about AT commands and their usage, refer to [1].

20
Network registration
GSM network registration
To check GSM network registration status enter AT+CREG? into the software (for
instance Hyperterminal). The modem will answer in following format:
+CREG: <n>,<stat>[,<lac>,<ci>]
OK
The following table shows the +CREG parameters:
<parameter>
Description
<n>
0Disables the network registration unsolicited result code.
1Enables the network registration unsolicited result code +CREG: <stat>.
2Enables the network registration and location information in unsolicited
reports and Read command +CREG:<stat>[,<lac>,<ci>].
The default is 0.
<stat>
0Not registered, and the ME is not currently searching for a new operator to which to
register.
1Registered, home network.
2Not registered, but the ME is currently searching for a new operator to which to register.
3Registration denied.*
4Unknown.
5Registered, roaming.
<lac>
Two-byte location area code in hexadecimal format
<ci>
Two-byte cell ID in hexadecimal format.
*To manage connecting to a network, the SIM card inserted into the modem must be valid.
For further information about AT commands and their usage, refer to [1].
