Overview
The RB900SG Terminal is the complete modem solution for wireless m2m applications.
It offers high level LPWA/2G/3G/4G features and RS232/485/422 communication interfaces
and USB interface for configuration. Together with its small size and wide power supply
range, it is easy to integrate it with energy meters.
The RB900SG terminal enabling high speed data transmission, SMS and TCP/IP
communication. The device can be controlled by standard AT commands and configured by
RB-Setup application, thus making it the complete SMT platform for m2m solutions.
This document contains full RB900SG modem description and gives information about
installation and using it.

External connections
GSM antenna connector
An SMA “ANT” input is used to connect external GSM/UMTS/LTE antenna. To establish
a connection with a GSM/UMTS/LTE network, an external antenna must be used. Type of
antenna depends of GSM/UMTS/LTE coverage. In good circumstances (level of received
signal is high) use antenna contained in the package. If the range of GSM/UMTS/LTE is low
or none, an outdoor or indoor (for instance in place where GSM/UMTS/LTE range is
sufficient) antenna should be used.
Note: If there is no antenna connected to SMA connector, the connection with
GSM/UMTS/LTE network is impossible.
GNSS antenna connector
An SMA “GNSS” input is used to connect an external GPS/Glonass antenna. To establish
connection with GPS/Glonass sattelites and check the coordinates of the device, an external
antenna must be used and should be located outdoors. GNSS is optionally available in
RB900SG-L2 and RB900SG-L5 modem variants.

10
USB interface
RB900SG terminal is equipped with a USB interface (as shown below). Type of
connector is miniUSB. It is used for device configuration.

11
RS232/RS485/RS422 interfaces
The RB900SG terminal is equipped with RS232/RS485/RS422 interfaces on RJ45
socket. Use the jumper to switch between interfaces. All available jumper positions are
presented in 7.1. Setting up the modem. The connector also carries the power supply from
the ITRON SL7000 or ACE6000 meter, therefore it is not necessary to use an external
power supply when connected to a meter.

SIM card holder
A SIM card holder is placed at the front of the RB900SG terminal (as shown below), and
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 insert drawer into the modem (you will
hear „click”). To operate the module in a GSM/UMTS/LTE/LPWA network, it is necessary to
insert a SIM card obtained from the network operator.

Using the modem
Setting up the modem
To set up the modem, follow these steps:
•At the production stage, the device is set up with a serial interface selected by the
customer. If there is a need to change the serial interface, open the device housing
and plug the jumper/jumpers on the appropriate connector of the internal board.
Possible jumper/jumpers positions are shown in the pictures below
RS422
RS232
RS485

18
•Connect the USB cable to the computer
•Configure the modem using the Teleorigin Manager program. It is recommended to
configure the modem without the SIM card inserted. Using the application, you can
save the PIN code of the SIM card to the internal memory and set the APN, APN
user name/password, change the antenna configuration (internal / external) and
TCP/IP listening port. The "Data" tab contains standard information about the
modem, such as signal strength, name of the network to which the modem is
logged in, modem firmware, IMEI serial number, GSM / LTE module model and
local IP address. If you cannot connect to the modem, follow these steps:
- check if the modem is connected to the computer via the USB interface
- check if the COM port number is correct
The detailed configuration procedure is described in the "Teleorigin Manager User Manual"
document.
•Disconnect the USB cable after setting up the device.
•Screw the GSM / LTE antenna on if an external antenna is to be used.
•Remove the SIM card tray by pressing the yellow button as shown in the picture
below.
•Insert your SIM card into drawer.
•Verify if SIM card fits in the drawer properly (as shown below).
