Raw Start Chip Data / Raw Finish Chip Data / Bib# to Chip ID Data / Participant to Bib#
Multiple chip reads occur for each tag as it enters the energized field. For those starting in the second start wave, gun time deducts approx. 3 minutes 43 seconds (length of time between starts). Below is an explanation of how to under stand the raw chip data. “Participant to Bib#” file includes bib number, name, gender, age.
Example: Tag with an ID = 580011223344 is read at 14:05:20.39 on 2006-12-30 the date packet received from the reader would be:
aa00580011223344090006123014052027xx\r\n
where xx is the calculated LRC.
| Byte | Description | Info |
| 0 | Header character 1 | Frame header, ‘a’ |
| 1 | Header character 2 | Frame header, ‘a’ |
| 2-3 | Reader ID | 0-255 in ASCII hex |
| 4-15 | Tag ID | MS digit first, excluding CRC |
| 16-19 | I and Q channel counter | Binary counters 0-255 in ASCII hex |
| 20-33 | Date/Time | Date and time with 10ms resolution. 390ms/10=39-”27″ (27= 0×32 + 0×37) and the month 12 is 0×31 + 0×32. |
| 34-35 | LRC | Checksum on bytes 2 to 33 |
| 36-37 | End of packet (CR,LF) | 0x0d, 0x0a |
