Serial CHOP
- Invalid title: ""
Summary[edit]
The Serial CHOP is used for serial communication through an external port, using the RS-232 protocol. These ports are usually a 9 pin connector, or a USB port on new machines. (Using a USB port requires a USB-to-serial adaptor and driver.) All of a computer's available serial ports can be found in the Device Manager under the Windows operating system. Their names begin with 'COM'. Example: COM1, COM2, COM3, etc.
This CHOP monitors changes in its input channels, and sends the corresponding script through the serial connection. Any ASCII numeric digits '0'..'9' that are received, are stored and reflected in the output channel named 'return'.
When you need to receive more complex data, other than simple ASCII numbers use the Serial DAT.

Parameters - Common Page
Time Slice timeslice - Turning this on forces the channels to be "Time Sliced". A Time Slice is the time between the last cook frame and the current cook frame.
Scope scope - To determine which channels get affected, some CHOPs use a Scope string on the Common page.
Sample Rate Match srselect - ⊞ - Handle cases where multiple input CHOPs' sample rates are different. When Resampling occurs, the curves are interpolated according to the Interpolation Method Option, or "Linear" if the Interpolate Options are not available.
- Resample At First Input's Rate
first- Use rate of first input to resample others.
- Resample At Maximum Rate
max- Resample to the highest sample rate.
- Resample At Minimum Rate
min- Resample to the lowest sample rate.
- Error If Rates Differ
err- Doesn't accept conflicting sample rates.
Export Method exportmethod - ⊞ - This will determine how to connect the CHOP channel to the parameter. Refer to the Export article for more information.
- DAT Table by Index
datindex- Uses the docked DAT table and references the channel via the index of the channel in the CHOP.
- DAT Table by Name
datname- Uses the docked DAT table and references the channel via the name of the channel in the CHOP.
- Channel Name is Path:Parameter
autoname- The channel is the full destination of where to export to, such hasgeo1/transform1:tx.
Export Root autoexportroot - This path points to the root node where all of the paths that exporting by Channel Name is Path:Parameter are relative to.
Export Table exporttable - The DAT used to hold the export information when using the DAT Table Export Methods (See above).
