The wire ends of the detection antenna are connected to the connection box.

Because the detection antenna is sensitive to interference, which can for example be radiated
from any nearby electrical cables, it is necessary ( if possible ) to keep away 5m - 15 ft the
antenna from these cables. Also try to keep away as far as possible the coax cable from other
electrical cables.

It is also advisable to minimal 5m – 15ft keep away other parts of the track from the detection
antenna, to prevent false transponder readings.

2.3  Timing and identification decoder

On the moment the timing transponder is above the detection antenna, the number will be
read. The timing and identification decoder will link the passing time and sends this
information in a record to a connected time management computer, by way of a RS232 serial
link.

2.5  Operating the timing and identification decoder

After the metal plug from the mains powered adapter is connected to the DC power supply
input of the decoder, the timing and identification decoder will start-up. First a self-test is
performed to check the main functions of the timing and identification decoder. The decoder
display shows all performed tests. If the self-test passes, the unit is ready.

From this moment on, the decoder will register all timing transponders passing the detection
antenna. From every detected transponder, the display shows :
