Performing a remote antenna SD reset
Connect the transmitter to the service to be identified, place the antenna on the red cable as previously described with the label
pointing away from the transmitter.
Press the “i” button. The screen will change to something similar to the below.
0
SD
Press the “M” button as indicated by the “SD” icon. The screen will then revert to the one below with arrow pointing forward. This
indicates that the reset was successful.
SD-EUR95dB
The system is now ready to identify the cable at the location of the interest.
Identifying a cable
Having confirmed the antenna is synchronized with the receiver, proceed to the location the cable is to be identified. Place the
antenna on each of the suspected cable in turn ensuring the correct orientation, ie the arrow on the antenna pointing away from
the transmitter.
Note the signal strength on each cable and also which arrow is illuminated. The target cable will have the strongest signal and
will have the green forward arrow illuminated.
Enhancing the loopback method of cable identification with the aid of the SD signal
As described before, a more reliable method of loop backing the signal on the cable is possible if the cable is out of service. This
method can be further enhanced with the aid of the SD signal.
Method:
Set up the transmitter as below, with the far end connected together and with the transmitter connected across a twisted pair of
cable. Set the transmitter to SD EUR or SD USA and perform an SD reset as described above.
At the location of interest, hold the antenna on each of the cables in turn. Run the antenna along the cable keeping the arrow
on the antenna pointing forwards. On the incorrect cable the signal level will be small and steady. On the correct target cable
the signal will rise and fall in sympathy with the twist in the cable. Also, if on the target cable, at alternate peaks the arrows will
switch from forward to backward pointing.
