GPRS modem router simplifies M2M connections

Radio Data Technology has released the RM6000 GPRS modem routers to simplify M2M data connectivity following successful field trials in the water and traffic management industries.

Available in Din rail, IP67 and bare board versions, it is claimed to be simple to deploy as it shifts intelligence and interfacing into the modem router. This inbuilt interfacing and control system means that even legacy equipment and simple stand alone sensors can be provided with full two-way remote communications and alarm capability either to the internet, or point to point.

In addition to the modem functionality, it can generate email or SMS alerts and manage the upload of data via FTP.

The series was designed to let users stock a single modem router for all applications. It features RS232, Ethernet and USB interfaces as standard. The USB port allows live configuration and real time monitoring of data without interrupting the link.

Digital and analogue IO is expandable for direct interfacing to sensors and alarm functions. Quad band (850, 900, 1800 and 1900MHz) GSM and GPRS class B and class 10 connectivity is available for multi-region capability.

It supports UDP, TCP, IP, PPP, ARP and Ping, enabling point-to-point, transparent tunnelling, FTP, HTTP, SMTP and Pop 3.

An onboard controller allows the use of a gui for configuration of the modem via USB. The gui simplifies programming and setup, and provides monitoring functions and error logging. By using a series of pull down menus and entering basic data, the system can be configured in minutes with no knowledge of AT modem commands.

Via the gui, engineers can set all basic modem parameters such as baud rate and parity. In addition, extended features can be rapidly configured. These include building email and SMS alert lists, triggered by the changes on the IO interface, establishing automatic connection on power up, setting the real time clock, network re-registration and keep-alive functions.

“The RM6000 frees system designers to simply connect devices instantly rather than work through the time consuming process of integrating and coding that is required to support a board level GPRS module,” said Alan Hall, managing director of RDT.

“Our design philosophy at RDT is to make radio communications transparent to the system and its users. Via GPRS, the RM6000 can provide a drop in replacement for our existing UHF modem units, but it also offers new capabilities beyond raw data transmission such as SMS, email and FTP, which make interfacing with conventional computing and communications technology trivial.”
