Starting with ChronOS version 184.108.40.206, you can use a USB keyboard/keypad to type in bib numbers. This will record a read for that bib number when you press Enter on the keypad.
Typing in reads is an excellent back-up in case there is an issue with antennas or tags during the race. Entering keyed reads as a backup doesn't require a rocket scientist, so you can easily have an untrained volunteer enter keyed reads as finishers cross the line, freeing you to take care of more important matters.
Collecting Keyed Reads
No matter what screen you're on in ChronOS, you can type in Keyed reads. If you want to see the last 5 keyed reads and antenna reads, you can go to the Race Ops > Tags and Markers > Keyed Bibs screen.
Simply type in the bib number of an athlete, and press Enter. The controller will record this entry as a read.
As you type a number, you'll see it appear in the area highlighted below. This is useful for verifying you typed the right thing before you press Enter.
Streaming Keyed Reads
Keyed reads are classified differently in data files than reads collected with an antenna. When streaming tags through Fusion, StreamManager, or SimpleClient, you must select 'Keyed' or 'Keypad Mode' as the tag mode. Usually, it's best to stream Keyed reads separately from antenna read types. This is an excellent way to ensure that Keyed reads can be easily applied to a Priority 2+ Timing Device in CT Live.
If you are processing data through Fusion or SimpleClient, you can process Normal and Keyed reads simultaneously.
