RDS P332 Technical Manual

Following information is provided for better understanding to the RDS principles and the user defined group coding. The largest element in the RDS coding structure is called a "group" of 104 bits each. Each group comprises 4 blocks of 26 bits each. Each block comprises an information word and a checkword. Each information word comprises 16 bits. Each checkword comprises 10 bits. All information words, checkwords, binary numbers or binary address values have their most significant bit (MSB) transmitted first. The data transmission is fully synchronous and there are no g ...

COMSPD Port 1 Speed (0-4) Specifies the port 1 speed (baudrate). 0 - 1200 bps 1 - 2400 bps (default) 2 - 4800 bps 3 - 9600 bps 4 - 19200 bps This command has the same effect as SPEED but the format of input is different. COMSPD=1 CT Clock Time and Date (0, 1) Enables (1) or disables (0) time and date transmission in CT format. CT=1 DATE Date Specifies the actual date in DD.MM.YY format. DATE=30.11.05 30th of November 2005 ECHO Terminal Echo (0, 1) Determines if the RDS encoder sends an echo (1) of each character or not (0), that it receives via the port. ECHO=1 EXTSYNC ...

H (000000-FFFFFF) Day, Month and Year coded as Modified Julian Day. To find D, M and Y from MJD: Y' = int [ (MJD - 15 078,2) / 365,25 ] M' = int { [ MJD - 14 956,1 - int (Y' × 365,25) ] / 30,6001 } D = MJD - 14 956 - int ( Y' × 365,25 ) - int ( M' × 30,6001 ) If M' = 14 or M' = 15, then K = 1; else K = 0 Y = Y' + K M = M' - 1 - K × 12 To find MJD from D, M and Y: If M = 1 or M = 2, then L = 1; else L = 0 MJD = 14 956 + D + int [ (Y - L) × 365,25] + int [ (M + 1 + L × 12) × 30,6001 ] Y', M', K, L - intermediate variables.

This additional information provides all details required for implementation of the P332 protocol into your application (broadcast automation system, messaging system, TMC data source etc.). Please see also the Annex 1 - Communication Protocol Implementation Flowcharts. Some source code examples are provided on the website. 11.4.1 Unidirectional or bidirectional – What is the difference? The P332 supports both unidirectional and bidirectional communication modes. Nothing is required to be set, the mode of operation results only from the method of communication. ...
