Data stream statistics• Measurement of:
– Frame rate (Area-scan only) – Line rate
– Data rate
• Configurable averaging interval
Event signaling and counting• The application software can be notified of the occurrence of various events:
– Standard event: the EVENT_NEW_BUFFER event notifies the application of newly
filled buffers
– A large set of custom events
• Custom events sources:
– I/O Toolbox events
– Camera and Illumination control events – CoaXPress data stream events
– CoaXPress host interface events
• Each custom event is associated with a 32-bit counter that counts the number of occurrences
• The last three 32-bit context data words of the event context data can be configured with event-specific context data:
– Event-specific data
– State of all System I/O lines sampled at the event occurrence time – Value of any event counter
Number of lines20 I/O lines:
• 4 differential inputs (DIN)
• 4 singled-ended TTL inputs/outputs (TTLIO)
• 8 isolated inputs (IIN)
• 4 isolated outputs (IOUT)
Usage• Any I/O input lines can be used by any LIN tool of the I/O Toolbox
• 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
• The LIN and QDC tools outputs can be further processed by the other tools (DIV, MDV, DEL) of the I/O toolbox to generate any of the following "trigger" events:
– The "cycle trigger" of the Camera and Illumination controller
– The "cycle sequence trigger" of the Camera and Illumination controller – The "start-of-scan trigger" of the Acquisition Controller (line-scan only) – The "end-of-scan trigger" of the Acquisition Controller (line-scan only)

Power outputNon-isolated, +12V, 1A, with electronic fuse protection
I/O Toolbox toolsThe I/O Toolbox is a configurable interconnection of tools that generates events (usually triggers) from input lines. The composition of the toolset is product- and firmware- dependent.
• Line Input tool (LIN): Edge detector delivering events on rising or falling edges of any selected input line.
• Quadrature Decoder tool (QDC): A composite tool including:
– A quadrature edge detector delivering events on selected transitions of selected pairs
of input lines.
– An optional backward motion compensator for clean line-scan image acquisition when the motion is unstable.
– A 32-bit up/down counter for delivering a position value.
• Divider tool (DIV): to generate an event every nth input events from any I/O toolbox event
• Multiplier/divider tool (MDV): to generate m events every d input events from any I/O toolbox event source.
• 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).
• 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.
