Overview
The RB900SG Terminal is the complete modem solution for wireless IoT applications. It
offers high level LTE features, 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
Teleorigin Manager application, thus making it the complete SMT platform for IoT 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-L5 modem variant.
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.
NOTE: To configure the modem with SIM card inside, please plug also the power adaptor.

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.

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 RS232 serial interface. If there is
a need to change the interface to RS422 please connect the modem to Teleorigin
Manager and choose „422” in „Serial” -> „Serial type” in „Basic” menu tab, save the
configuration and reboot the modem. To change the interface to RS485 open the
device housing and plug the jumper on the appropriate connector of the internal
board, close the housing and set „485” in „Serial” -> „Serial type” in „Basic” menu
tab, save the configuration and reboot the modem..
