For a right TRDS4001 codifier working, its important to observe with attention as
follows:
1)
The TRDS4001 coder has to be installed immediately before the transmitter,
either for stereo transmissions or the mono ones.
2)
The connections has to be realized with most possible short screened cables.
We recommend cables not longer than 3 meters.
3)
Realize with care the input and output connections in order to reduce drones
and background noises.
4)
Place the codifier far from heat sources and in not directely sun radiations facing
areas.
5)
Check that the range voltage which will supply the system is as desired.
6)
Make a backup copy of the CD supplied with the equipment before use it.
7)
Do not open the rack containing the system.
8)
Clean the system only with a dry and soft cloth in order to avoid finishings
damages.
9)
In case of damages, switch off the system and contact directely the
firm R.V.R. ELETTRONICA s.p.a.
6.4 Hardware Installation
The TRDS4001 RDS encoder can be connected to an exciter basically in two ways:
it can add the RDS signal to a MPX input signal and then supply the resulting
baseband signal to an exciter accepting MPX input or,
it can just generate the RDS signal synchronized with an external 19 kHz pilot
tone
The following figure gives a schematic example of the two ways of installing the
encoder.
