6. Linkgate EncRadio SF: safety features
for radio transmission
To overcome unreliability and the various problems associated with the old system of radio
transmission of impulses, LINKGATE Encoder SF offers a number of innovative solutions:
6.1. Digital transmission of impulses
Linkgate EncRadio SF transmits sets of data (no longer a single impulse) that contain a vast
amount of information. In particular, the following are transmitted:
• The transmitter’s Code (software selection from 127 channels and redundancy length data)
• Bib number (selectable with software)
• How long ago the event took place
• Battery Status (Low Battery)
In addition, the kit contains numerous control codes and error auto-correction codes which prevent
a signal from being incorrectly interpreted during reception.
All the data (information + control codes) is transmitted 16 times, in order to reduce the possibility
of reception failure.
Even with very disturbed signal transmission, this system ensures maximum reliability and
precision (+/- 0.4 thousandths of a second); in short, you only need the complete reception of a
single set of data to be able to reconstruct the original time of the event.
