Once you have set up a Stream to collect reads on, whether it's a File Type Stream, or a Direct Type Stream, you'll need to assign it to a Timing Location in order to begin collecting reads.
To get started, click the "Timing Locations" menu item on the left hand sidebar:
Next, click "Settings" on the Timing Location that you'd like to assign a Stream to:
Next, click the field under "Main Streams" to assign a Stream to be considered for your reads. You can assign multiple Main Streams to a single Timing Location to consider reads from them equally.
You can additionally assign Backup Streams. Any times that come into Streams that are assigned as a Backup Stream on a Timing Location will only be considered if there is not an instance of that bib or chip passing on a Main Stream assigned to the same Location.
Once you have your Streams set here, click "Save" to continue on in your Race Setup.
