RDS:
select Enabled or Disabled. If Enabled, enter:
– Data Source: select Internal, Ext. ASCII, Ext. UECP, ASCII Over IP, or UECP Over IP
– Injection Level: enter value between 0 and 10%; typically 5%; this level is added to the
composite baseband
– Phase: enter value in degrees between 0 and 360
– Baud Rate: select 75, 150, 300, 600, 1200, 2400, 4800, 9600, 19200, 38400 or 57600 bps;
displayed for Ext. UECP and Ext. ASCII sources only. Does not apply to internal data
sources.
– PI Code (hex) (Program Identification code): enter four hex digits that represent the
station call sign (e.g., PI=1AE5); this unique code is used to identify a broadcast station.
Every station gets assigned a specific code with a country identifying prefix. In the USA
this code is determined by applying a formula to the station's call sign. Additional
information can be found at www.nrscstandards.org. This selection applies to internal
data sources only.
– PS Code (programme service code): this is simply an eight-character “tagline” static
display that represents the call letters or station identity name. Most RDS capable
receivers display this information and, if the station is stored in the receiver's presets, will
cache this information with the frequency and other details associated with that preset.
This selection applies to internal data sources only.
– PTY: this coding of up to 31 pre-defined programme types allows users to find similar
programming by genre. This selection applies to internal data sources only.
Note:
For RDS operation, an external unit or software can send data to the exciter. The exciter
generates the RBDS carrier and injects the data. Nautel supports the strings listed below. The
data format is XX=yyyy.
Note:
For ASCII over IP data, for ASCII Over IP data, send RDS information to the IP address of
the VS1, port 7005
