FAQ
Use the AWT100 configuration software on a PC connected via RS485. Open the correct COM port with matching baud rate, then read/write parameters. The device status LED indicates proper operation.
Yes, AWT100-4G/WiFi/CE models have built-in data storage. When the connection to the cloud is lost, data is saved locally and automatically retransmitted once the network is restored.
Up to 30 MODBUS RTU devices can be connected via the RS485 bus.
AWT100 can be powered by DC 24V directly, or by AC/DC 220V using the optional AWT100-POW power module.
Overseas versions (model suffix “HW”) use MQTT protocol with JSON data format, while domestic versions use Acrel’s proprietary protocol.
