  • Computer with Windows operating system
  • Service cable kit
  • Flat head screwdriver
  • Terminal block
  • Service cable driver
  • Terminal program with a command line interface (CLI), such as PuTTY or TeraTerm
These instructions and examples use and refer to PuTTY. Another program with a command line interface can also be used, but the user interface looks different.
The AQT530 address is different in Beacon Station and Connected Compact Station than in Beam Weather Station. Change the address before connecting the sensor to Beam.
  1. Disconnect the cable from AQT530.
  2. Download the service cable driver from www.aten.com/global/en/products/usb-solutions/converters/uc232a/.
  3. Connect your computer to AQT530 with the service cable kit.

    Connect the open-ended cables of the power source to the adapter and attach the adapter to the DC power connector (10–25 V DC).

    Alternatively, connect your own power source directly to the DC power connector.
