Wireless Systems – EncRadio Multi Frequency 500mW

The EncRadio transmitter is now available with a more powerful radio transmitter.

The function features are the same as for the EncRadio MF (multifrequency) system with a power of 10mW, but the greater power of the embedded radio transmitter makes it possible to cover longer distances (about 9 km in good conditions) and so guarantee better reception in those zones in which it is difficult to receive the signal sent by a standard transmitter (10 mW).

LinkGate EncRadio allows to:

to transmit start and finish impulses and also 14 individually identified intermediate impulses
to acquire up to 16 passing speeds via radio from the same number of acquisition zones
to manage consecutive events with a single transmitter, for example the double start or finish of parallel slalom
to guarantee maximum reliability and accuracy (higher than +- 0.4 thousandths of a second) even when transmission disturbance is particularly severe, thanks to its exclusive high redundancy transmission code with error correction
to retransmit an unreceived signal repeatedly even after a long time lapse, simply by pressing the repeat key.
to automatically store all the start, intermediate and finish times, which can later be transferred and assigned to the Racetime2 and REI2 stopwatches.
to command MicroTab and MicroGraph displayboards without using cables.
to set (with the two large buttons on EncRadio) the competitor number to which the event taken should be assigned and to transmit it automatically via radio to the stopwatch
to reach a transmission distance of about 2 km in good conditions
to select 32 different radio frequencies on which to operate
to select 128 different transmission channels
