I am in the process of upgrading my D100/D120 to Dual HDX. I think we are almost there. There is a problem with the A/P setup. The network configuration shows the 2 servos ready; in fact, all devices are being seen and ready. However the A/P setup section is greyed out. Servos have good power and ground and the A/P disconnect circuit is open. Any ideas on why I can't get into the A/P setup sectioin? Thanks in advance.
