You will need a wired serial RS485 connection to the Jandy Power Center (Control Panel).
  • If you have an inside controller/keypad mounted on your wall this is usually the best place.
  • If not, the outside control panel is the next best place.
    • Note. The AqualinkD Radxa Kit is not waterproof or suitable for extreme climates. However, it can be mounted outside in a waterproof box in mild climates.


If your installer followed the Jandy wiring, below are the colors, and where to connect them to on a USB2RS485 adapter, or AqualinkD RS485 HAT.
Note the pinouts are different between RS Power Center and RS485 HAT
