KAM Processor lockup problem.
According to the Kantronics experts I talked to, a lockup of the
processor which I experienced sporadically can be caused by using a power
supply which has a large capacity in the output circuit or one with a slow
collapse time to 0V when power supply is turned off or during a mains power
failure or interuption.
(Mine had a large cap in the output and no regulator)
This caused the KAM or KAM-Plus to lockup and it needed a hard reset and
new parameter setup to restore operation.
Cure: Use a separate small power supply for the KAM-Plus with a fast collapse
time to 0V when the AC input it is removed. It works!
Have fun and keep on KAMing
