  • Page 3: Introduction

    Polifemo-Radio is a highly innovative instrument in the field of radio transmission of timing impulses. Thanks to technical innovation, the old impulse transmission systems have been replaced by data transmission which ensures maximum precision and reliability thanks to transmission redundancy and the use of error correction codes.

    Doc: POL_R_200_006_E POLIFEMO-RADIO Version: 2.0 User manual Page 4. OPERATING MODES The Polifemo-Radio photocell works by reflection: the maximum operating distance between the photocell and the reflector is 30 metres. Max 30 m Fig. 3 4.1. CENTERING Centering takes place in the following way: when switched on, the photocell emits a continuous BEEP, pointing the photocell on the reflector, the BEEP stops, thus indicating correct centering.

  • Page 6: Selecting The Channel

    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.

    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 •...

DISABLING RADIO TRANSMISSION To disable wireless event transmission, set the 4 dip switches of CHANNEL SELECTION (Switches 4-7) to the position ON (see Figure 5).

  • Page 9: The Outputs

    Page 6. THE OUTPUTS The Polifemo photocell emits a signal on the output, normally open, and is brought to the reference level (COM socket – BLACK banana jack) if the infrared beam is interrupted The signal is presented on the green banana jack (OUT2) and is compatible with every type of timing device.

  • Page 10: Recharge Management

    7.1. RECHARGE MANAGEMENT Recharging the Polifemo batteries can only take place with the photocell off and is managed 'smartly' by the microprocessor in the photocell itself. The standard procedure is to discharge the batteries and then to fully recharge them. Recharging starts after insertion of the power supply jack with sufficient voltage (Vch>8V) and the photocell off.
