Programming Soundtraxx Tsunami with Digitrax Zephyr

[Herc Driver]

I re-read some posts about programming the Soundtraxx Tsunami sound decoders "in the blind" with Digitrax equipment and took the plunge. Since the loco took off like a shot at about .5 on the speed dial, I decided to reprogram CV02, 06, and 05 to the values Digitrax suggests. No real change was noticed in the engine. Since there was absolutely no creep speed or slow speed, I adjusted CV02 to a value of 10 (from 28 as Digitrax suggests) and that made a great impact on the slow speed. Now, the engine creeps and has a great slow speed crawl. Plus, the sound better matches the actual engine movement.

I did the reprogramming in the Page mode, following the directions in the Digitrax book. The only thing you can't do is "read" back the CV value after you modify it.

I'm just glad it actually "took" and wrote correctly to the speed values. Now, the engine moves much more realistically. Whew...
