The USR-G780s is a new high-reliability 4G positioning DTU for the IoT. As the second-generation Smart DTU, while maintaining the first-generation hardware interface and form factor, it continues the industrial quality design, improves the protection level for harsh environments, and expands the applicability in more fields. The product has the characteristics of high speed and low latency, and supports 4G Cat-1 network access of the three major operators. The product has a built-in independent hardware watchdog, which reaches the high protection level of EMC4; Wide voltage power supply, RS232 and RS485 two standard interfaces, stronger applicability; 8 years of traffic will be delivered immediately after leaving the factory, 100M/month, and the application can be networked after powering on. With GNSS global positioning system, it can be connected to manned cloud, Qianxun cloud and private cloud platform; For the first time, it is equipped with a power-off alarm function, which can be combined with the manned cloud to achieve remote and efficient operation and maintenance, and there is no longer an ineffective business trip to the site.
