Programming and Reading CVs
Certain command stations also allow you to read a CV during Service Mode
Programming, which is useful to verify its current setting. If you have trouble
reading or verifying CVs, the problem may be due to the design of your
command station and not the sound decoder itself. Tsunami and all other
decoders communicate back to the command station using what’s called an
acknowledgment pulse, which is defined in NMRA RP-9.2.3 as “an increased
load on the programming track of at least 60mA for at least 5ms.” Like most
decoders, Tsunami generates the acknowledgment pulse by momentarily
applying power to the motor.
If your sound decoder is otherwise working properly (i.e., responds properly
on the mainline to speed and direction commands) but your command
station is having troubles reading CV data from the decoder, it may be due to
incompatibilities between the electrical requirements of the Tsunami (which
are different from conventional decoders due to the added audio circuitry) and
the electrical characteristics of your programming track. In such an event, you
will need to use a Programming Track Booster, such as SoundTraxx PTB-100
(P.N. 829002). The PTB-100 amplifies the programming track signals to levels
that work best with Tsunami. It is easy to install (see below) and inexpensive.
An advantage to using the PTB-100 is that it also provides short circuit
detection and some helpful diagnostics. It works well for all other SoundTraxx
decoders, too.
