The ATEW series wireless communication module is a cost-effective CAT14G DTU that supports 2GGPRS mode. It can realize RS232/485 to 4G, which is very suitable for communication and data monitoring of various serial PLCs and serial devices, while achieving high-speed transmission, low latency, and support for new technologies.
The ATEW series wireless communication module can configure devices, upgrade firmware, and configure advanced settings such as MQTT/JSON through the serial port. At the same time, it supports remote centralized management of a large number of distributed devices through the server, and can remotely configure, remotely view status, and remotely upgrade programs. It can realize device management on the Web side and data viewing and remote control on the Web side.
