The 1216L is not initialized = no A/D readings. The Rotator page says "Rotator not initialized!" and the System Info says "1216L HW >= 5, disconnected" + "Rotator status Error, code=9". Do you have a 1216L-5 or one of the older versions? Too me it seems that either the wiring between the 1216 and the 1216L is faulty or some other hardware error.
