GTP-230 is an intelligent 3G Multi-Function Controller. Within the high performance 32 bit CPU, GTP-230 is suit for the hard industrial environment. It features 3G module, 2 RS-232, 1 RS-485. It can be used in M2M application fields to transfer GPS and data of Modbus device via WCDMA/GPRS. GTP-230 has two functions for different requirement, RMV function and SMS function. Therefore, GTP-230 is an ideal solution for environmental monitoring and remote device management for M2M applications.
