Pentair Screenlogic Screenlogic2 Protocol Adapter 520500 520489 *From 522104 kit

We also REPAIR ScreenLogic adapters. If you are looking to replace a bad adapter, please consider our REPAIR SERVICE instead. SEE OUR OTHER LISTINGS. Otherwise... This adapter has been reconditioned with our special process no one else performs. The onboard flash drive has been wiped clean and tested before reflashing with Pentair’s most recent firmware. We open every one, inspect and flash directly to the internal Logic Circuit board just like at the factory. Includes the 4 terminal connector as shown.
