It was developed at a time when TCP/IP connectivity did not exists on most transmitter sites and sometimes only one serial data channel was available for entire site. Today, most of the addressing job is usually done either at the TCP/IP layer (by specifying IP address of the RDS encoder) or by taking the data from satellite channel which is usually particular for each station.
Thus most stations require no encoder address (use the "0" wildcard) or a single encoder address is sufficient. The same applies to the site address. Two or more site/encoder addresses may be useful in some special cases, for example if only a part of the network carries TMC data and all encoders are connected to one serial channel, while need to retain a possibility of individual configuration for each encoder.
Limit for the number of addresses is not specified anywhere. Our encoders support up to two addresses for the Encoder address and up to two addresses for the Site address.
