<DataStream>
16 ASCII coded hexadecimal characters (blocks A to D of the
RDS groups)
TRANS=0 deletes all transparent data and switches back to nor-
mal RDS data transmission.
Note:
16 characters must be specified for each data sequence.
Leading zeros, if any, must also be specified. The data will be
transmitted even if it constitutes no meaningful RDS data.
Example:
STEReo:DIRect "TRANS1=0123456789ABCDEF"
The data "0123456789ABCDEF" is sent instead of the RDS
data.
Example:
STEReo:DIRect? "TRANS1"
Reads the transparent data.
Response:
"0123456789ABCDEF"

Alternative Frequency Lists
Alternative frequency lists can be transmitted in two ways:
●
Method A:
The frequencies of an AF list are entered one after the other; the frequency cur-
rently transmitted has to be specified as the first frequency.
●
Method B:
The frequencies of an AF list are entered in pairs, each pair containing the fre-
quency currently transmitted and an alternative frequency. The frequency pairs
should normally be entered in ascending order. Descending order should be
chosen only if the alternative frequencies belong to different regions or are used to
broadcast different programs at different times.
Do not combine methods A and B!
Method A:
1. Generate a new alternative frequency list with
STEReo:DIRect "AF=N,87.6,87.7,87.8"
.
2. Set the group sequence, e.g.
STEReo:DIRect "GS=0A,14A"
.
The group sequence must contain group 0A.
The alternative frequencies are now transmitted in group 0A.
3. Add another alternative frequency list with
STEReo:DIRect "AF=+,88.6,88.7,88.8"
