Guest Posted March 5, 2008 Share Posted March 5, 2008 I was moving ISY to its permanent location. After plugging in PLM, RX light stays constantly on. Instructions say either PLM or cable is bad. I tried two different cables, same result. I tried factory reset on PLM and ISY. No change. ISY retained all Scenes, but all programs are gone from memory. I tried to import my programs back, but after saving them, summary page says "not saved" for all of them. Maybe it is an ISY issue and not a PLM? Does this mean I need to contact SH for replacement PLM? Mark Link to comment Share on other sites More sharing options...
Michel Kohanim Posted March 5, 2008 Share Posted March 5, 2008 Hello Mike, Yes! If RX light is solid on it means that ISY cannot communicate with the PLM and thus in SAFE mode in which case you will not see any of your programs (don't worry, they are still there). If you have used different wires with the same outcome, then it has to be the PLM. With kind regards, Michel I was moving ISY to its permanent location.

Sub-Routine Posted March 5, 2008 Share Posted March 5, 2008 You might check the pins where the cable connects to the PLM. I have read that these can sometimes be bent down and prevent good contact. Rand Link to comment Share on other sites More sharing options...

Rand The PLMs are indeed prone to stuck pins. One guy who had the same symptom fixed it with a sewing needle and took a picture of how the "unstuck" connector should look: http://arachnoid.com/home_automation/system_controller.html. -Jim Link to comment Share on other sites More sharing options...
Guest Posted March 6, 2008 Share Posted March 6, 2008 Thanks Rand and Jim. There are no stuck pins in my case. I have another PLM on order. If indeed this is a PLM fault, I will exchange the defective unit with SH. It seems like reliability of the setup might be enhanced by having spares always at hand .

Sub-Routine Posted March 6, 2008 Share Posted March 6, 2008 It was worth a shot since you moved it. Have you tried a factory reset? Is the LED on? Link to comment Share on other sites More sharing options...
