Not sure. I'm not a hardware expert so I don't know the significance of that.
From the WE manual, Jumper J100 must have pins 3-4 connected; from the A3000 jumper table on BBoAH, J100 should have pins 1-2 jumpered.
Similarly, J102 has pins 1-2 jumpered for the WE, whereas the A3000 manual requires pins 2-3 jumpered.
Note: I am assuming the A3000 jumper settings are the same as the A3000T. I DON'T KNOW if this is the case. Maybe someone can confirm this.
I went through this a couple of weeks ago when I temporarily removed the WE from my A3000D so it is still fresh in my mind. You should confirm the above settings yourself in the WE manual & BBoAH in case I have made some typos.
