bolingerbe, i'm not sure whats going on with your problem. It seems although your receiving a couple of bytes, i think that may just be noise or something (0x7,0x7E are 0b01111111 & 0b01111110). Double,triple check your baud rate, your wiring and VDF register settings. You need to get it working so that it displays the correct values for PD001 & PD002 in the setup dialog.
