3. STARTING UP
3.1. Setting jumpers for ‘Loop Through’ or ‘Side Chain’ mode
Before installing the RDS Encoder Silver in an equipment rack, you should determine how it will interface with
your other equipment, particularly the exciter or pilot transmitter.
There are two ways to connect the encoder to your exciter, ‘Loop Through’ and ‘Side Chain’.
In ‘Loop Through’ mode, the multiplex/composite signal passes through the encoder on its way to the exciter,
with the encoder adding the RDS modulation to the signal.

In ‘Side Chain’ mode, the encoder output is separate from the multiplex/composite signal, and connects to the
exciter at a designated RDS/57 kHz subcarrier input.
