    GT-531

    GT-531 is an intelligent Modbus SMS/GSM Gateway for industry M2M applications. It is convenient for users to apply to M2M applications with the host like PC, PLC, HMI and PAC. It supports UNICODE format for users to send SMS messages to the specific mobile phones by Modbus protocol with various language. That can make the current system to M2M applications. Moreover, the GT-531 also supports the sound alarm application with the pre-defined voice files. It can be used to inform operator the urgent event immediately. For managing more GT-53x series remotely, ICP DAS provides SMS DBS software for users to apply in the system.
