Ahhh...so you aren't directly connected to the ISY...you are using an ethernet bridge...I was hoping to try the Hexin directly connected to the ISY... PoolController--->RS485--->HXSP-485A (link below)--->ISY http://www.hexin-technology.com/RS-232_ ... t-242.html should I rethink?

Thanks...are you using an isolator/surge suppression device on your system wired between the ISY and the Pentair? My controller is wired directly to the equipment pad via 200ft of 485 that runs underground...so just a concern... Thanks again!!!

This is really interesting information...I just installed a Jandy pool controller that has serial inteface capability...did you have to use any additional isolators with the Hexin converter? The Jandy serial converter is $400, but I don't see it doing anything special beyond converting the 232 to 485 protocall.. http://www.jandy-downloads.com/pdfs/Aqu ... manual.pdf Thanks again for the helpfull information
