Fixes the relative phase shift between the pilot tone and the RDS signal.
Changing the value by one results in 9.5 degrees phase shift change.
The value serves only as a scale, it may not provide real phase shift value.
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
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 ]
This command is no longer supported.
Indicates if pilot tone is present (1) or not (0).
Disables (0) or enables (1) the RDS subcarrier generator. Does not affect any other functions.
Provokes a hardware reset of the RDS encoder and is equivalent to an "off-on" cycle of the RDS encoder.
Selects unit(s) with specified address. Unit addresses 0 and 255 are equivalent. Only selected units accept other
commands. For address range 1-254 the unit is selected for 20 minutes (selection timeout). For address 0 and
255 the unit is selected for unlimited time after power-up. If a unit is selected, other units are unselected
immediately.
This command has no effect on UECP reception which uses individual method of addressing.
Note: If only one unit is connected to the port and has address 0 or 255 (default), there is no need to use
SEL command and the addressing feature needn’t to be taken into consideration.
SEL=0
Selects unit(s) with address 0 and 255.
SEL=3
Selects unit(s) with address 3.
SEL=ALL
Selects all units on the port (or also a unit with unknown address).
