Jandy Serial interfaces
Do they really need to suck so bad?
My 2nd one just died at my house. This will be the 3rd in 3 years.

Lightning strikes could be the reason. You may be lucky, and it is sacrificing itself instead of a processor.

They are not great but they also contain IC with tiny wires that are susceptible to small surges. How are you protecting the unit from surges? Both RS-485 and RS-232 should be surge protected to ensure the life of the interface but also the equipment connected to it. Even then, they'll fail. Outdoor wiring will cause all manor of havoc with a low voltage device.

My age it means less
The country I come from
Is called the Midwest
I's taught and brought up there
The laws to abide
And that land that I live in
Has God on its side.

As luck would have it, I need to order one of these this week.
Any idea where to pick it up at a decent price?
Our local Jandy folks are dumb as a post, even with the part number they are having a hard time finding it in the price book.

I've seen them last a long ass time in many houses. You need to make sure you have an opto-isolator between the pool side of things and the RS-232 device. If you don't, then any lightning hit near your property can easily cook it and anything connected to it. It isn't that the device sucks...it's more that you have an electronic device that is pretty much out in the open for electrical storms to destroy.

0There's a difference between surge protection and lightning protection. A standard RS-232/485 "surge protector" won't do squat for protecting that interface during a nearby strike. You need an optical isolator for protection on the interface box and lightning protection at the pool end.

Surge is definitely needed on these, I use optical isolators when I have any say in the matter..

The part that comes with the Jandy marked isolator is just three wires connecting one side to the other, I use the 9SP0P2 from here. My rule has always been to optically isolate if it leaves the rack.
