59059Re: [Z_Scale] Re:TCS announces 2 new DCC decoders for AZL and MTL
- Dec 10, 2008Jeff:
Thank you for an absolutely excellent write up concerning these DCC decoders. It was very well written. When you state that the Z2 is a 2 function decoder, what does that mean, exactly? For instance, I have the Digitrax drop ins in my MTL engines. How would one describe these Digitrax 123?? decoders?
Oh, I was also in contact with Norm's and his TCS decoders are "on the way to him."
Thanks for the information.

The MZ4A's won't ship until January and there will be plenty
available so no one should be "out of stock" as they will be promptly
While these are unproven or tested mainstream in Z, they are an
existing design from the N and HO series that are simply relaid to
fit in the Z locos. So I have faith. Plus 4 function versus 2 on the
MTL loco version (we like to put in addtional lights rather than the
common 2 function Forward and Reverse lights) I'm switching.
The TCS's will fit more easily. The Digitrax DZ123MO mounting
notches are slightly off location so you have to file the 'rear' ones
about 1/32 of an inch farther back so they will propertly start in
the 4 mounting posts.
Both will work. Both (actaully all decoders) have Back Elecro Motive
Force (BEMF) that tries to compensate for speed changes with loads,
up/down grades or slow speed runnign. You can EASILY turn it off on
the TCS decoders by hitting F6 on your DCC Cab (hand held throttle)
or by changing CV61 to 'permanently' turn it off (or on). Digitrax
and others do not have the convenience of Cab Function controlling it
and require CV changes to turn it off/on. Some Z locos may not run as
well with it on, some run better. Normally, it is not a good idea in
Consists (or MU for Multiple Units e.g. 2 or 3 locos lashed together)
as one will try and compensate and then the other tries to compensate
so you sometimes see this surging difference between the 2 or 3
locos. There are normally several variables that can be changed to
tweak it but the loco performance or position in a consist or even
the direction can screw it all up. Turn it off in these cases.
You can order the Digitrax DZ123M0 (that's a zero at the end) from a
number of places where as existing TCS resellers will have to stock
up on the TCS Z products. Norm's Trainworld
(http://www.normstra inworld.com/ dccz.htm) back in New England WILL
have them in stock ! Guaranteed.
