T A 

T raffic Announcement:  

This is a 

temporary

 flag added to the RDS 

data stream 

only

 as a traffic bulletin is being aired.  Some RDS car 

radios can be set to search for traffic bulletins among various TP 

stations (see 

T P

 below) while tuned to a listener’s preferred 

program, or even while playing a tape or CD.  As soon as any TP 

station broadcasts a traffic bulletin, the receiver 

temporarily

 

switches-over to receive it.  When the bulletin is finished, the 

receiver switches back to the original program, tape or CD.

 

T DC 

T ransparent Data Channel:  

Conceived prior to common use of the 

Internet, the TDC would have allowed a continuous stream of 

broadcast data to be routed to a personal computer or to a printer.  

The listener could print merchants’ money-saving coupons or 

even an abbreviated newspaper.  It has been suggested that the 

TDC could be used for MP3 music downloads, though the low 

throughput of RDS would make this really quite tedious.

 

T MC 

T raffic Management Channel:  

This is a data channel for advanced 

automobile traffic information and traffic management.  The 

European CENELEC group has defined the coding for this 

service, though the group keeps this information close to its 

collective vest.  TMC is not used in the US.

 

T P 

T raffic Program Identification:

  The TP flag identifies the station as 

one that routinely broadcasts traffic bulletins for motorists as part 

of its normal, everyday programming.  The TP flag is displayed on 

the receiver faceplate, indicating that the radio is searching for 

traffic announcements.  The radio keeps track of TP stations 

offering this service to speed up the search-and-switch process. 

R DS  

Injection 

L evel 

‘Page’ 9 of the LCD screen gives both a digital readout and an 

analog bargraph display of the RDS subcarrier injection level.  For 

this measurement to be accurate, the Model 510 must be 

calibrated with reference to 100% carrier modulation, as described 

on Pages 7 and 8 of this Manual.

 

Groups 

Displayed 

L ist 

‘Page’ 10 of the LCD screen lists the RDS groups being 

transmitted.  Because some groups are sent infrequently, this 

listing is 

cumulative

.  If more groups are seen than are 

anticipated, reset the Model 510 by cycling the power off and back 

on.  This will clear the register.

 

RUNNING T HE OPT IONAL S OFT WARE 

The Model 510 Decoder/Reader can send raw RDS data to a PC.  

Output data contains everything encoded into the RDS data stream, 

including groups or special-purpose functions that are not decoded 

by the Model 510. 
The software diskette that is included with the Model 510 provides 

only elementary decoding of the basic data groups, essentially 

duplicating the Model 510 front-panel LCD display.  If further
