Witty·TAB
LED DISPLAYBOARD WITTY·TAB
WITTY·TAB is the ideal choice for anyone seeking a multi-capable, lightweight, easily transportable and user-friendly display board.
Measuring 13x41.5x6 cm, the board is equipped with a Led dot matrix displaying 6 numeric digits of 7 segments each (10 x 5 Leds), and a sensor allowing automatic adjustment of the brightness level to suit the ambient light conditions.
Brightness can also be controlled manually.
The 2 lead storage batteries guarantee stand-alone operation for at least 10 hours without the need for a connection to the a.c. mains supply.
The WITTY·TAB display board has an internal timer and comes complete with a radio transceiver able to communicate with Witty photocells: as the athlete passes, the photocell transmits the pertinent signal (start/lap/stop) to the board by radio. The transmission range is 150 metres under standard conditions.
The WITTY•TAB display board can be used in 2 different modes:
• on its own, in combination with Witty photocells only; in this mode, times are simply displayed, without being saved for subsequent computer analysis
• in combination with the Witty timer; pulses transmitted by the photocells are received by the board and by the timer independently, but in this case, with the timer function, data can be saved and stored for analysis subsequently on a computer using the WittyManager software package
