theedudenator Posted February 20, 2015 Posted February 20, 2015 Had a power failure at the house. I guess this knocked the PDM out. The green light on the PDM would not turn on. Have the new one plugged in, it shows the green light. ISY 99 will not connect. When I start ADMIN it states "safe mode" When I "restore PDM" I get Error -20000----30
LeeG Posted February 20, 2015 Posted February 20, 2015 The ISY needs to be powered down when connecting the new PLM. Power up the new PLM, then power up the ISY. Be sure to follow Wiki instructions for replacing PLM.
theedudenator Posted February 20, 2015 Author Posted February 20, 2015 I followed the wiki I tried it again. When I go to admin screen Your System is in Safe Mode Restore PLM Modem Insteon_errors--30 -2000000/-30
Brian H Posted February 20, 2015 Posted February 20, 2015 Have you tried a different cable between the PLM and the ISY99i? You may want to open a support ticket with UDI. If you followed the wiki and still get the safe mode. There is a small chance the power surge that took out the PLM. Also damaged the serial port in the ISY99i.
theedudenator Posted February 21, 2015 Author Posted February 21, 2015 The fifth time I tried it it worked...
