Okay, I just receive by SV-1000 and SV-700 screens and set them temporally in my panel. My EMS220 was install perhaps six months ago along with the ADAHRS. I hooked the network cable from the ADAHRS and EMS220 and powered up the SV-1000 screen. Neither the ADAHRS or the EMS is recognized by the SV-1000. The EMS200 is receiving power. Didn't confirm same with ADAHRS but have no reason to doubt that it is. What am I missing?
