I have installed 2 systems recently, and was thinking to use X10 IR remotes (Marmitek EasyTouch35) setted to sed the X10 commands thru IR instead of RF.
I tried to make a test with X10 receive code A1 OnResponse, doing Keypad Announce, Word TEST.
I obtained no Announcemente on the keypad and went to the IO Monitor, to see if the IR command was passing thru the Rs485 Bus.
I took a look at the Comfort manuals again... LOL, and saw that i needed to do a thing that hadn't done by mistake, that was to join the ground of the Comfort pannel, to the ground of a secondary power supply, feeding the SEMs and KPs.
I thought it would work after that, because it was even logical that it wouldn't work without the GNDs linked.
After this, I went to another of my clients, and once I was there, and he had a previous firmware, I tried to test the same thing on that system and was well succeeded! IO Monitor Shower XFxxx....
Did anyone had this experience?
Do you think that it is due to powering the SEM and the KP from another power supply?
