I/O Toolbox Tools

The I/O Toolbox is a configurable interconnection of tools that generates events (usually triggers):

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.

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.

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).

Divider tool (DIV): to generate an event every nth input events from any I/O toolbox event source.

Multiplier/divider tool (MDV): to generate m events every d input events from any I/O toolbox event source.

The 'Input Tools' (LIN, QDC and UAS) can be further processed by the 'Event Tools' (DEL, DIV and MDV) 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)
