Available in DIN rail, IP67 and bare board versions the RM6000 is considered to be the simplest GPRS modem router 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 readily be provided with full two way remote communication and alarm capability either to the Internet, or point to point. In addition to the modem functionality the RM6000 can generate email or SMS alerts and manage the upload of data via FTP.

The RM6000 series was designed to allow customers to 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 I/O (expandable) for direct interfacing to sensors and alarm functions.
  • Quad band (850/900/1800/1900MHz) GSM/GPRS class B, class 10 connectivity for multi-region capability.
  • Supports UDP, TCP, IP, PPP, ARP, PING enabling Point-to-point, Transparent Tunnelling, FTP, HTTP, SMTP and POP3. Enabling file uploads, email and web page updates.
  • NAT Routing and DHCP to support multiple hosts.
  • GPRS ‘Always On’, stay alive connection and Dynamic DNS (DDNS) functions for reliable connectivity.
  • IP67, DIN rail mounting bare board versions.
  • DC power input of 9 to 36.
  • SMA connector for a choice of external antennas.
  • GUI set up — no more AT commands.

The RM6000 has an onboard controller, which allows the use of a GUI for simple configuration of the modem via USB The GUI simplifies programming and setup, offers 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 I/O 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.” Alan Hall, managing director of RDT explained. He continued, “Our design philosophy at RDT is to make radio communication 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 communication technology trivial.”
