5.3. SELECTING SIGNAL TYPE
Switches 1 to 3 make it possible to set the type of impulse you wish to transmit . The following
table summarises the types of impulse available.
SWITCH 1 SWITCH 2 SWITCH 3 Signal type
ON ON ON START
OFF ON ON LAP 6
ON OFF ON LAP 5
OFF OFF ON LAP 4
ON ON OFF LAP 3
OFF ON OFF LAP 2
ON OFF OFF LAP 1
OFF OFF OFF STOP
5.4. IMPULSE TRASMISSION
By using a switch (switch n°8 next to the words TRASMISSION TIME) you can set transmission
duration (approximately 2.3 seconds for long transmission and 0.6 seconds for short). By selecting
long transmission, you will obtain greater redundancy of information as the same data will be
transmitted 16 times. If you select short transmission the set of data will only be transmitted 4 times
so you will have lower redundancy but with a substantial reduction of transmission time.
For normal use, we advise you always to use long transmission (switch n°8 OFF) ) in order to
maximise the redundancy of transmitted data. However, for special applications such as the taking
of several intermediate times very close together, using short transmission is the only practical
solution if transmissions are not to overlap.
5.5. THE RECEIVING DEVICE
The DecRadio_SF modules are powered directly from the Microgate chronometers using the special
connecting cable. It is very simple to use:
• connect the Nucletron connector (see Fig. 4 N° 2) to the corresponding connector on the
chronometer
• screw in the antenna (see Fig. 4 N° 1)
• check that the channel set on the photocell corresponds to the channel set on the chronometer
(consult the relative manual for the chronometer).
