ME-1 no signal audio

I have 3 me-1 connected through D snake. I can only get signal to one of them. All inputs are assigned on all 3 but can not get signal on 2 of them. Im using QU 32. Help

Elaborate a bit more, how do you have them connected to the Dsnake port. In series or using a switch.

Have you moved them around for testing, putting a non working one in the location of the working one?

When you say that all 3 are configured, tells me that they each have their own independent power pack for power, yes?

POE power does not work when you daisy chain devices. (This is true of any POE device including regular networking gear). This means that while the console or ME-U can provide POE power, it will only power the first device plugged into the network port. If you are daisy chaining the ME devices to each other, the second, third, and following devices will need to be powered through another method. The easiest method is to connect an appropriate power supply (voltage and amperage) plugged directly into the "daisy chained ME units.
