I'm finding standard 12V wall warts work fine on the ISY99, but not the Polisy. The Polisy jack's center pin appears to be a bit larger than on most 12V connector plugs. Is it a different specification? 

Strangely, a lightning strike took out the Polisy brick and I subbed an old one from the ISY, no issues.

Thx!

ISY is 5.5 mm X 2.1 mm and Polisy is 2.5mm. Some cables will work for both, like this one I used https://www.amazon.com/gp/product/B016BJGZ2U/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

Details, including mini UPS is in 

 

Thx @TexMike, that's perfect. I'm running the ISY and Polisy off UPS-backed PoE with the rest of the core network, and didn't want to jam a plug over the pin. I'll make a cable for it, and this time 5.5 x 2.5. Thanks! ?
