avittech Posted June 28, 2011 Share Posted June 28, 2011 How long is the run? What type of wire? 2.1 and Jandy pool controlJune 9, 2011Product: Composer Jandy Pool Control DriverTopic:.Jandy Pool Control Will Stop WorkingAffects: We have found that there is a common factor in systems running 2.1 that have a Jandy pool controller installed in the project that will stop communicating with the control 4 system within a few weeks operation. Detail: Jandy has supplied us with some information regarding the RS232 communication requirements for the controller to work properly. In every one of the cases we have seen this issue; the dealer has used a cat 5 cable for the serial cable communication. This is not a supported method by Jandy. Action: Replace the cat 5 cable with the required 18 AWG bus wire that Jandy requires. In every case we have seen this cat 5 issue , replacing the cabel with 18 AWG bus wire has fixed the communication issue and control was reestablished.

henniae Posted June 28, 2011 Share Posted June 28, 2011 Interesting. I think the install manual for the Jandy even states that 18 ga. wire be used. Link to comment Share on other sites More sharing options...
Vegas Posted June 29, 2011 Author Share Posted June 29, 2011 Thanx, we will try this cat5 was used and we doubled up the wires overall 18 g will provide less resistance... I will post the change .. Thanx again Link to comment Share on other sites More sharing options...
Bud Posted May 21, 2012 Share Posted May 21, 2012 I am about to hook up Jandy RS pool controller. I have read throught the instructions and the threads. I am just trying to make sure I have the best way to do it. I have a Jandy RS 8 controller. It looks like this Jandy 7620 serial adapter is required:http://www.polytecpools.com/jandy-7620-generic-serial-adapter-vantage-lite-touch-lutron-cestron-and-elan-p-284.htmlMy pool controller is 100+ feet wire distance away from my rack with HC-800 and IO extender. I plan to run 18Ga wire to from the Jandy RS controller to my inside rack and place the Jandy 7620 serial adapter inside in the rack. Then I will have a short serial cable to connect it to the C4 controller or IO. I know the Jandy manual says 30 ft but that is not going to be practical and I'm pretty sure I've read about others with similar distances. I figure that the 485 communication on the Jandy side will handle the distance better than the RS232 on the C4 side. Thanks. Link to comment Share on other sites More sharing options...
Godzilla Posted May 21, 2012 Share Posted May 21, 2012 i would run 18/5 in case you need to double up some..........its the voltage that needs to be correct at the adapter....i used cat5 and had to double up to get the right voltage.....was awhile ago so dont remember the voltage needed.

Bud Posted May 21, 2012 Share Posted May 21, 2012 Thanks for the reply. I think they pulled 18/7 not knowing what we would need. From the Jandy manual it looks like there are 4 wires for that run (485). Seems to say to double up power (10V) and ground. Link to comment Share on other sites More sharing options...
roddymcg Posted October 13, 2012 Share Posted October 13, 2012 Something to note when using Catx, use one pair for Data + and Data -. Then double or triple up the pairs for power. Link to comment Share on other sites More sharing options...
