SO the Zephr Xtra is programmable? F0-F28? I mean, what can it do exactly? Im really close to ordering one cause for $175 it looks like a lot of DCC for starting out.
I agree, it really is a lot of DCC for the money.
Many questions above, really requiring some "background" first:
- The base/command station (doesn't matter which version) isn't "programmable" per-se, but rather allows you to program decoders - eg, you can set "start voltage" on a loco by loco basis. "Top speed" is also programmable - from - the base station. You can even do a complete speed curve (think exponential) and much more magic that need not concern us for now.....
To me, and I've already said some may disagree, the ability to *read* what you've got in, eg, CV02 ("Start voltage") is helpful - I like *knowing* what I'm changing! Both the Zephyr & Super Chief support this, the SEB doesn't.
Furthermore, and IMO more significantly, the Zephyr & SC have a separate, low powered, output to feed a "programming track" - This can be an isolated section of your pike with a switch controlling which output reaches it - ie, it can be an integral part of your layout for general use and switched to make it the programming track - You drive your loco onto it, flip the switch to "program output" and can now read and write any CV's without disturbing anything else on the layout.
The SEB only supports what they call "broadcast write" which sends programming commands to the entire layout - Which should therefore have everything else either removed and/or disconnected - That way you know you're only "hitting" the target decoder. Did the change take? You really have no way of knowing as you can't ask the base station to "display the value of CV02".
Furthermore, I believe the SEB programs at "full power", which never seemed like a good idea to me - You've got to really mess up to smoke a decoder on the programming track......
As for F0-F28 - Their web site certainly claims the new Zephyr will do it, but I don't have one so can't test it..... My original version says it will address F0-F8, but I do know that coupled with the DT400 I can access at least thru F12, which is as far as I've needed. I guess there's some kind of "shift" function on the Zephyr that allows you to access these high F#'s.
Incidentally, the detailed description of the Zephyr on their site has not been updated with details of the new version, only the comparison chart.....
HTH, cheers,
