Posted February 17, 20196 yr My friend gave me a ISY994i with Smartlink Controller #2412N, but i doesn't work, the RX light is on, and i see safe mode on APP. question is: is it compatible? Thanks! i'm new user and i want to learning .
February 17, 20196 yr The ISY 994i requires the 2413s PLM. https://www.smarthome.com/powerlinc-modem-insteon-2413s-serial-interface-dual-band.html When the ISY boots up in the safe mode it's because it can't communicate with the PLM
February 18, 20196 yr If it was a 2412S. It would have worked. The 2412S was the older hardware power line only PLM. The 2412N is a network connected module. Not the RS232 Serial Port needed for the ISY994i to work. It also had a reputation for the Network Board to fail.
