o Data rate
2. Configurable averaging interval
Event signaling and counting1. The application software can be notified of the occurrence of various events:

o A large set of custom events
2. Custom events sources:
o I/O Toolbox events
o Camera and Illumination control events
o CoaXPress data stream events
o CoaXPress host interface events
3. Each custom event is associated with a 32-bit counter that counts the number of occurrences

o Event-specific data
o State of all System I/O lines sampled at the event occurrence time
o Value of any event counter

• Selected pairs of I/O input lines can be used by any QDC tool of the I/O toolbox to decode A/B signals of a motion encoder

I/O Toolbox toolsThe I/O Toolbox is a configurable interconnection of tools that generates events (usually triggers):
1. Line Input tool (LIN): edge detector delivering events on rising or falling edges of any selected input line.
2. Quadrature Decoder tool (QDC): a composite tool including:
o A quadrature edge detector delivering events on selected transitions of selected pairs of input lines.
o An optional backward motion compensator for clean line-scan image acquisition when the motion is unstable.
o A 32-bit up/down counter for delivering a position value.
3. Device Link Trigger tool (DLT): delivers an event on reception of a valid high-speed CoaXPress 2.0 connection trigger packet message from the remote device.
4. User Actions Scheduler tool (UAS): to delegate the execution of 'User Actions' at a scheduled time or encoder position. Possible user actions include setting low/high/toggle any bit of the User Output Register or generation of any User Events.
5. Delay tool (DEL): to delay up to 16 events from one or two I/O toolbox event sources, by a programmable time or number of motion encoder ticks (any QDC events).
6. Divider tool (DIV): to generate an event every nth input events from any I/O toolbox event source.
7. Multiplier/divider tool (MDV): to generate m events every d input events from any I/O toolbox event source.
8. The 'Input Tools' (LIN, QDC, DLT and UAS) can be further processed by the 'Event Tools' (DEL, DIV and MDV) to generate any of the following "trigger" events:
o The "cycle trigger" of the Camera and Illumination controller
o The "cycle sequence trigger" of the Camera and Illumination controller
o The "start-of-scan trigger" of the Acquisition Controller (line-scan only)
o The "end-of-scan trigger" of the Acquisition Controller (line-scan only)
