Step 2: Configuring the Decoder
The next CV you may want to customize is CV 29 (Configuration Register 1).
Customizing CV 29 requires setting its individual bit variables, as we briefly
addressed in the “Bits and Bytes” section of this manual. CV 29 is used in
conjunction with other CVs to set a multitude of decoder characteristics, such
as direction and alternate power source enable.
Table. B.
CV 29 – Configuration Register 1
Bit 7 Bit 0
MD 0 EAM 0 ACK APS F0 DIR
Primary or Extended Address (EAM) – Bit 5 (EAM) of CV 29 determines
whether the decoder will respond to the primary address in CV 1 or the
extended address in CVs 17 and 18 (see “Configuring the Address” for more
information).
Alternate (Analog) Power Source (APS) – Bit 2 (APS) of CV 29 allows the
decoder to work with an alternate power source (such as DC) when a DCC
signal is not present as set by CV 12 (Alternate Power Source).
Note: The SoundCar is shipped from the factory with analog mode disabled.
Table C, on the following page, lists the correct decimal value to program
into CV 29 for a variety of operating modes. To use the table, locate the row
with the operating characteristics you desire and program CV 29 with the
associated value.
Note: Table C values are in decimal format. If your command station requires
hex inputs, you will need to convert using Appendix A.
Refer to the Tsunami SoundCar Technical Reference for more CV 29
details.
