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).
