RDS300/RDS500/RDS1000 User Manual 3.10
6. USING THE UECP PROTOCOL
6.1. ABOUT UECP
As RDS progressed and grew in Europe, a need was seen to have some form of standardization
amongst different RDS encoders from various manufacturers. The output protocol of the encoders to
the receivers in the listening area was already defined, but what was needed was a standard for
communication and control of a network of disparate encoders with a single protocol. UECP, the
Universal Encoder Communication Protocol, was created for this purpose, and finalized by the
European Broadcasting Union (EBU), as document SPB490. The protocol was accepted by CENELEC.
6.2. UECP AND THE RDS1000
The RDS1000 is fully UECP capable, and conforms to all of the recommendations of the EBU-UER
SBP490 document and all of the CENELEC standards regarding UECP. The UECP protocol establishes a
way to address encoders in groups or individually, and sets standard methods for unidirectional and
bidirectional communication, software models within the encoders, mechanical specifications, data
formats, message structure, message codes, handling of RDS data, including ODA, and remotely
configuring encoders. There is a great deal of information to be understood to implement use of
UECP on your encoders, and there are other, better documents that contain the information specific
to UECP. That being said, there follows a list of some of the more common UECP commands that are
accepted by the RDS1000.
NOTE:
The manufacturer’s specific command, 2D, followed by the manufacturer designation KV
will allow you to send any valid command to the RDS1000 via UECP.
Example : send of a valid character chain (PS_Text=…… in UECP).
