The RMV-511 is an intelligent multiport serial to GPRS gateway with I/O for industry M2M applications. It is designed for linking RS-485 devices to a GPRS network and remote I/O monitor. The user-friendly Axiom Driver/Utility and VxServer allow users to easily turn the built-in COM ports of the RMV-511 into standard COM ports on a PC. By virtue of its protocol independence, a small-core OS and high flexibility, the RMV-511 is able to meet the demands of every network-enabled application. In addition, the RMV-511 also supports GPRS network automatic re-connection function when the RMV-511 is broke the GPRS network by something happened. It also supports remote I/O monitor via virtual COM by Modbus RTU protocol. M2M solution will improve the service quality and reduce operating costs. Many application areas can be improved by using RMV-511.
