I purchased an ISY99i controller from Smarthome before the holidays and received it the day before Christmas. I mechanically and electrically hooked up on January 1 but to date I have been unsuccessful in linking a single Insteon device. The ISY seems to be working as I can access the menus and have set time, location and am able to sync with my computer but there is no response when I try to link a Switchlinc V2 Dimmer (2476D). Diagnostics show the PLM is not connected so I suspect that is the immediate cause of not linking. I cannot find any details on the LED for the PLM (2413S version 1.0) but I believe it is off, red and green as I have seen the red and very infrequently the green but mostly no light. I have done the reset several times but have failed to get no other LED light but a brief red light after the 3 second hold when plugged in. The light extinguishes and then nothing. Should it turn green and hold after plugging in? Is this an indication that the PLM is not working properly? I referenced the forums for Insteon and Universal Devices for some hints and did not find much help yet other than more than 6 months ago Universal Devices was advising not to use the 2413S but rather a previous (non-dual band) model 2412S. My ISY firmware version is 2.7.15 which I understand is not the latest but I am reluctant to update before I discern the possible problem with the PLM. I have both reset and reinstalled the PLM and the ISY several times without much luck and have spent several hours researching and tinkering. I have switched the Cat 5 cords carefully assuring connecting the right ports to the router (Linksys WRT160N V3.0) and PLM. I am leaning towards a malfunctioning PLM but am not so familiar with the hardware as to rule out installation error or something that can be remedied by a procedure.
