QUOTE: Digitrax, NCE, and Lenz all have a true two-way multiple access network. Each command station communicates with the throttles. This is evident with the DT400 (Digitrax) and the ProCab (NCE) in which information from the command station is displayed.
QUOTE: As far as adding boosters to an NCE system, nothing is easier than daisy-chaining them with RJ11 phone cable available from Radio Shack.
QUOTE: Address 00 is used to broadcast command to ALL devices/decoders on the layout. Every NMRA compliant decoder will respond to instructions sent on address 00 - that is the NMRA spec. For example, the command for emergency stop.
QUOTE: stretches the pulse negatively or positively to make the non-decoder equipped locomotive move. For simplicity's sake, we'll say the voltage applied to the rails is AC (though it is truly not AC but that is way beyond the scope of this forum). When the non-decoder equipped loco is sitting still, you will hear a noticable hum coming from the motor. This is the AC going back and forth equally in each direction. The motor is going back and forth so fast that it doesn't move (plus you are burning out the motor as DC motors aren't meant to be exposed to such signals). When you use the throttle to move the loco forward, the command station changes the pulse from being equally back and forth to being slightly more forward than backward. You will notice that the faster you go, the more the hum dimenishes. The same thing happens when you go in reverse but the pulse is stretched more negatively (or backward) than positively (forward).
QUOTE: The ability to do this with a non-decoder equipped loco makes it non NMRA compliant.
QUOTE: Originally posted by milesdf What you said is all true, except the part about no one going from NCE to Digitrax, as I know some people that did just that. NCE is easier to use, but the Digitrax's LocoNet is much more powerful, reliable, and expandable, due to a true two-way Multiple Access network, which none of the other systems have. In my opinion Digitrax is a much better choice for large layouts due to the ease in adding additional boosters. Also, your "irrefutable" fact: QUOTE: - Digitrax is not NMRA compliant because they modified their system to allow a non-decoder equipped locomotive to run on address 00 which is spec'd out to be a broadcast address. is refutable because there is no address 00 brodcast over the rails, only inside loconet, which does not violate NMRA guidelines. The address 00 on your remote only communicates to the command station, which then raises power on the rails but does not send a DCC command (causing an analog train to move), leaving 00 open for brodcast on the rails.

QUOTE: Originally posted by AntonioFP45 Wow! Good input guys. Helpful too! So far, it "Seems" like the two top contenders here have been Digitrax and NCE! Not to say that the other systems don't offer advantages but this matchup here "sort of" resembles Toyota vs. Honda or Chevy vs. Ford. [C):-)][C):-)] It would be good if some of you could offer specifics such as: [;)][blue] What does this brand offer thats edges out this other "brand". Thanks, guys!
QUOTE: Originally posted by rororo I was wondering which non- tethered system would be considered to be a "good buy " . Is anything in wireless cab available at an decent price ? Thanks.
