P232U RDS Encoder

The P232U RDS Encoder is well suited for the vast majority of radio stations which use serial data channel (PC serial port, satellite link, serial over Ethernet) for the RDS content distribution. An independent USB communication port provides a simple way for local connection and configuration. The RDS encoder supports both dynamic and static operation. The device is equipped with standard analogue interface for seamless integration into the broadcast chain and interchangeability with other brand products.

Some features are unique: output data monitoring down to the bit level, direct conversion of XML tagging data to Radiotext Plus, port multiplication thru Windows control software and several others. Due to support of additional RDS2 data-stream, the P232U is future-proof equipment, ready for possible enhancements of the FM broadcasting.

This RDS encoder is characterized by proven concept, easy installation, great price and unsurpassed text processing capabilities. It maintains support for all RDS services and data formats that are commonly used. The device is compatible with P132, P164 and backward compatible with PIRA32.
