Has anyone tried to use the Atlas DCC Commander as a booster to a Digitrax system ?

Just wondering if it was possible, I have a friend with the Atlas DCC system and he

borrowed my Zephyr to try out on his home layout. He already has a DT400 to use at the

club but bought the commander at Xmas time (sigh).

I was hoping tht he could merge the two systems for a 5 amp capacity, double gapped of

course, and also have his DT400 to run it with. WHEW

No answers at either company site for this combination.

Don't think so myself, but here I am asking.....

I can not visualise a functional mix of Atlas 'Slave' and Digitrax 'Master'.

The first issue that comes to mind is how is the DCC signal going to be

transferred from the Digitrax 'Master' system to the Atlas 'Slave' system?

The Digitrax system uses the Loconet to transfer the DCC data from the

'Master' command station through the 'Slave' booster to the trackage of the

'Slave' district. If Atlas DCC is Loconet compatible this is news to me. I

would be surprised if the DT400 will work on the Atlas system since the

DT400 also uses the Loconet protocol to communicate with the Digitrax

command station.

Bob Young,

There is a page on the Digitrax site:

---Links-Are-Forbidden--- gives directions on doing what i propose with a certain lentz system, my problem is in

not knowing if the Atlas DCC system (made by Lentz) will also be compatible.

I also found a note about reducing the Atlas's 18 volt output to a lower value.

No, this particular combination will not work. While you can use a

Lenz booster on a Digitrax system (and vice versa), it's not possible

to use the booster sections of either device without the throttle

being active.

It's not possilbe to feed the booster section of the Commander without

having the command station portion of the Commander active. You can

actually shut the booster off by setting it to slave mode. In slave

mode, the throttle and programming outputs are available.

On the Zephyr, you can turn off the command station portion. But you

can't turn off any of the rest of the system.

It MAY be possible to connect only pins 1 and 6 (the railsync lines)

of the loconet connector and have the booster supply power to the

track. This is how other Digitrax Command Station/Boosters can be

used as a booster with Lenz (and other) systems (as described by the

following application note on the Digitrax website: ---Links-Are-Forbidden--- I know you would have to set OpSwitch 2 to

'c'.

I would ask Digitrax before trying this. Depending on how the DCS50

is wired internally, it might work, but I can't say for certain.

Bob

The Lenz LV100 is a separate booster (or "Power Station" as Lenz describes it), so the track signal can be sent to it via Loconet to in turn provide the track power and that signal to another district. I plan to use this in my new setup, having migrated from a Lenz system.

I'd say the question would hinge on whether the Atlas Commander has some kind of switching allowing it to operate purely as a booster where another command station is present - and if it has the inputs the same as the LV100 to allow loconet pins 1 and 6 to be connected. If the website doesn't mention this functionality it could be a limitation of an entry-level "all-in-1" unit.

Isn't there a group similar to Digitrax for the Atlas Commander? Someone there should have encountered this question before.

The same DCC signal that's present colloquially on the Loconet cable are

also available on the DCC rails themselves and both are at the same voltage

levels. It's typically 'legal' to hook up a downstream non-Digitrax

booster, using the track signal as the DCC input to the booster, depending

on the booster's input requirements. It is not necessarily as nice a

solution as using the loconet carried version of the DCC signal, as there's

more opportunity for small variations in the signal, but typically the

booster will clean that up and there won't be any impact. As Mark Gurries

explained well in another series of posts, the DCC booster is reading then

recreating the DCC signal, rather than simply amplifying it, so minor

distortions on the input don't simply get amplified through to the output.

Another option is to expose the two wires in the loconet cable that carry

the DCC signal (being careful of the other wires) and use that as the input,

albeit without the convenience of a plug.

Again this depends on what signal level the booster is looking to use, but

most can take the levels present on the track.

Cheers, Peter

Wow, Thanks for all the replys.

I've down loaded the Lentz Compact manual.

But after considering the problems I might cause,

the best solution is for the friend to sell the Atlas

and get a Chief.

Thanks for all your thoughts.

This group is great.

Bob
