FAQ & Support
How do I run AT commands on the display?
Connect the Monitoring Display to a computer via a USB cable (using a CH340 driver if required). Open any serial terminal software (such as PuTTY or Serial Monitor) at **9600 bps, 8N1**. Type AT+HELP? to retrieve the full list of available diagnostic and configuration commands.
What parameters do the operating modes control?
Operating modes 1 through 8 enable or disable specific sensor inputs (Door, Water leak detection, and PIR motion sensors) in various combinations to prevent false alarms or customize event alerts. See the Operating Modes grid above for specific active combinations.
