I/O Indicators
The I/O indicators show the status of the counter inputs and digital I/O.
Inputs A and B from the rotary encoder share one indicator. Input Z from the
rotary encoder and the digital input (IN) also share one indicator. The shared
indicators are controlled via an exclusive-OR of the two inputs, e.g., the indi-
cator is OFF when both inputs are ON or both inputs are OFF.
The two digital outputs each have a separate indicator. The I/O Indicators are
described in the following table.
