Even with very disturbed signal transmission, this system ensures maximum reliability and
precision (+/- 0.4 thousandths of a second); the complete reception of a single set of data is all that
is required to reconstruct the original time of the event.
5.2. SELECTING THE CHANNEL
With the 4 CHANNEL SELECTION switches it is possible to set the transmission channel used by
the LinkGate EncRadio-SF (Encoder) module built into the photocell. The transmission channel is
used in such a way that only REI2, Racetime2 chronometers or displayboards
(µGRAPH or µTAB) set to the same reception channel can receive the transmitted signal as valid.
Consult the relative user manuals to identify or select the channel on the various devices. Selecting
the same channel number on the Polifemo-Radio you wish to use will ensure that only signals from
your own timing system are received. This type of filtering of received signals is particularly useful
as the selection of different channels allows the use of a number of systems (chronometer +
Polifemo-Radio) in the same zone without the risk of timing data causing interference.
The following table shows the different channels which can be selected:
