GTP-541M-UDR is a smart 4-G remote control device with inertial navigation. It is compatible with downward 2G/3G band and can be used with different software interfaces to meet user needs.. 4G remote control device transmits I/O signals to remote management platform through LTE/WCDMA/GPRS. Shunge also provides related software support to help customers quickly build monitoring terminal programs, including M2M RTU Center, VxServer, VxComm and other software.. In addition, users can switch GTP-541M-UDR functions such as ModBusSMS, DIOSMS and RMV by replacing the firmware with SD card to meet different application requirements. The powerful function of GTP-541M can reduce the development cost and time of users, especially suitable for the application of Internet of Things
