Miscellaneous Features
Transponding
If you are using Tsunami on a layout equipped with Digitrax transponding
block detection, you will need to configure Tsunami for transponding-friendly
operation. Be aware that the Tsunami itself does not transpond - you will
need to install an external transponding decoder in your locomotive to
achieve this functionality.
Simply program CV 62 to 1 to configure Tsunami for compatibility with
external transponding devices. To disable transponding compatibility (default
mode), program CV 62 to 0.
Note: Power to the decoder must be cycled before any changes to this CV
will take effect.
