    RMV-531 is an intelligent multiport serial to 2G/3G gateway for industry M2M applications. It is designed for linking RS-232/485 devices to a GPRS/WCDMA network. The user-friendly VxComm Driver/Utility and VxServer allow users to easily turn the built-in COM ports of the RMV-531 into standard COM ports on a PC. By virtue of its protocol independence, a small-core OS and high flexibility, the RMV-531 is able to meet the demands of every network-enabled application. In addition, the RMV-531 also supports GPRS/WCDMA network automatic re-connection function when the RMV-531 is broke the GPRS/WCDMA network by something happened. M2M solution will improve the service quality and reduce operating costs. Many application areas can be improved by using RMV-531.
