I/O Control Blocks

Every I/O line is controlled through one I/O control block.

Block Diagrams

There a 3 variations of the control block depending on the input/output capabilities of the I/O line:

I/O control block for bidirectional I/O lines

I/O control block for input-only I/O lines

I/O control block for output-only I/O lines

In the above drawings:

●

A thin blue line represents one individual electrical signal path

●

A thick blue line represents a collection of electrical signal paths

●

The blue arrowhead shows the propagation direction of the electrical signal(s)

●

A blue shape represents a functional element of the I/O control block

●

An orange (oval) shape represents a GenICam feature; the text inside being the feature name

●

An [x] appended to the feature name indicates that the feature is associated with a selector feature (in this case: LineSelector)

●

The orange arrowhead indicates the access-mode of the feature: read-only features having incoming arrows, writable features having an outgoing arrow.

Input Path

Input-only and bidirectional I/O lines share a common input path structure including:

●

The I/O port block representing the I/O pins on the I/O connector(s)

●

The Rx block representing the line receiver circuit

●

The Input Inverter block representing the user-configurable logic inverter

●

The Input Filter block representing the user-configurable glitch-removal filter

Output Path

Output-only and bidirectional I/O lines share a common output path structure including:

●

The I/O port block representing the I/O pins on the I/O connector(s)

●

The Tx block representing the line driver circuit

●

The Output Inverter block representing the user-configurable logic inverter

●

The Line Output Mux block representing the user-configurable source multiplexer
