The Ear

The Ear deserves its name, because it does a lot of listening:

• It listens to other timing systems and synchronises wireless when needed
• Multiple Ears can listen and synchronise their times wirelessly to one master ear before the event
• It listens to the gunshot. This allows all ChampionChip equipment to use the same start time as the official time.
• It can be used as a DeskReader, and listens to the 7digit character-code transmitted by the transponders.

The Ear is responsible for:

• Switching on and off the antennas on the road
• Keeping accurate time
• Data storage (chip codes and times)
• Passing on data to the central computer

• The Ear device connects to the Controllers and to a central computer.

The connection between the Ear and central computer can be made with a direct serial line or regular modem (wire), or by means of a cellular modem (wireless). The Ear holds a heavy-duty battery which has a capacity of 24 hours.

The DigiCase combines a digital controller and an Ear in one Pelican case. This means that the DigiCase can be used in combination on its own or as an Ear.
