3431.901 : OST4 start transducer (second transducer for backup signal)Typical Wiring Configuration
- These sturdy starting blocks, made of aluminium and stainless steel, feature an extra large 120 x 263 mm non-slip adjustable footrest for optimal stability, fully assisting the athletes’ performance.
- The loudspeaker transmits the starter’s instructions, the gunshot, and the possible false start signal.
- The rest pressure is adjustable from 20 to 40 kg. The distance between the feet, as well as the foot's start angle can be freely adjusted.
- Another handy feature is the control LED, providing indications during thrust sensor adjustments.

Built around a dedicated hardware, CHRONOS performs all the time-critical functions. The data is processed by an internal computer running under Windows CE®. An antiglare color LCD (backlit, 640 x 480 pixels, 65536 colours) provides enhanced contrast, even under direct sunlight conditions. The fast built-in printer provides live printouts.
ASC2 (Automatic Start Control) is suitable for all levels of athletics, and is compatible with timing installations manufactured by Swiss Timing. It enables up to 10 lanes to be monitored simultaneously.
The starting block sensors take account of the physiological response time, i.e. the time elapsed between the starting signal and the thrust of the athlete’s heel against the starting block. The system memorizes and prints all the reactions times occurring in the interval of one second before and one second after the starting gunshot. In the event of a false start, an acoustic signal is transmitted by the central station to the starter’s headphones and to the starting block loudspeakers.
Online data transfer is made possible via a RS422 serial line to a data handling unit and SCAN'O'VISION units.
An OST4 transducer for start pistol is included in the set. A second OST4 transducer can be connected simultaneously to the system as an option, in order to provide a backup signal, thus improving the total reliability.
The orders of the starter are amplified and easily understandable by the athletes in their individual loudspeaker. The volume of the voice calls and the volume of the false start warning sound can be individually adjusted.
