7 Configuration

The configuration procedure makes it possible to set up the unit for optimum performance and should
only be carried out by skilled, authorised personnel.
When configuring the TWT1A and TWRB1A models take particular care to prevent accidental contact
between the tool being used for regulation and the live parts (230V~), since the device must be powered when
carrying out the adjustments.
TRANSMITTERS
Active transmitter setup:
Set the dip switches to ON according to the distance of the cable in order to achieve the best video signal on
the monitor, (bear in mind that dip1 inserts the lowest equalisation and dip 3 the greatest; it is also possible to
set combinations of the 3 dip switches). Then, after adjusting the receiver, it may be necessary to change
slightly the settings made on the transmitter.
