Indicators:
Real-time incoming (IN) and outgoing (OUT) signal activity can be observed via LEDs on the
card bracket. Sampled every millisecond, color change occurs with a corresponding change
of signal state.
Unused, non-connected inputs and outputs will have an indeterminate state and assume a
value of 1 or 0.
